I'm finishing building a 120sqft shed in the back yard, learning Fusion 360, and hopefully getting my chronic sinusitis solved.

Poured a slab, designed, framed, used as much reclaimed lumber as I could, and sheathed a lean-to style shed. My first attempt at building a structure, and it's coming out nice. This is to replace the 64sqft 5' shed that a neighbors tree fell on earlier this year, but we really need the extra storage.

I got a Bambu P1S 3D printer for Father's Day to replace an old Ender 3 Pro, and it has just been a dream. TinkerCAD, while amazing and a very capable tool, I'm ready to move on to something else. I tried Plasticity, and it showed a lot of promise but I found it very frustrating, bumped against some missing documentation and ran out of free trial time. Tried FreeCAD 1.0RC/Ondsel, and it's a fantastic piece of software. Yesterday I decided to give Fusion 360 a try and it's just so much more refined. Started the Product Design Online tutorials on Youtube yesterday and the stuff you're building in the first 5 15 minute lessons are frankly amazing.

For me the most important issue that needs to be solved right now is the increasing urban sprawl and the car dependent neighborhoods. It causes social isolation. Maintaining infrastructure like roads and electricity, is causing a strain on the economy for local municipalities. Not to mention the disastrous effect car based transportation has on the environment.

I am a fullstack developer living in Norway. Last year I registered the Norwegian branch of the Architectural Uproar as a not for profit organization. With the support from paying members, I have been able to go on tour to most of the major cities in Norway. We organize large meetings were we discuss architecture and city planning with politicians, architects and property developers on stage.

I am strongly inspired by Create Streets in UK and Strong Towns in the US. I want to improve people’s quality of life, help saving the planet and make Norway beautiful again while doing it.

    There's a quote from Bill McKibben's forward to "Creating Cohousing" by Kathryn McCamant and Charles Durrett that I think about every time someone brings this up (it's about the U.S., but it applies to lots of other places and you may recognize your own countries development model here too, or not):

    "For fifty years, our economic mission in America, at its core, has been to build bigger houses farther apart from each other. And boy have we succeeded: a nation of starter castles for entry-level monarchs, built at such remove one from the next that the car is unavoidable."

    > It causes social isolation.

    What is it about suburbs in particular that causes social isolation?

    • iambateman 23 minutes ago

      The default suburban life leads toward a comfortable kind of solitary confinement. Someone who lives in a “single family home” equipped with air conditioning, a privacy fence, a big screen TV, a garage door opener, and the internet will tend toward isolation because all of those technologies make aloneness easier.

      The reader may point out that many people are isolated in big cities too. This is true – if an adult has decided to be alone, they can be. But in the city, one's lack of social connection is more often felt whereas a suburban home can diminish the effect, like ibuprofen taken for a headache.

      • randomdata 19 minutes ago

        How does that meaningly differ from rural homes, which do not have the isolation problem? Rural areas have the strongest social communities I have ever seen.

        • iambateman 15 minutes ago

          oh, wonderful question. I need to think about that some more.

    • SamWhited 20 minutes ago

      At least in the U.S. (and likely elsewhere) the design of the suburbs encourages neighborhoods with individual houses and very little walk able space (occasionally there are sidewalks or parks in the richer areas, but developments may be large and they're not evenly spaced throughout). Exclusionary zoning in the U.S. has also reduced the number of "third spaces" (coffee shops, malls, grocery stores, barber shops, etc. where people congregate and meet) near or in neighborhoods. This means fewer chance encounters since you have to plan to both go out in a car to meet. You have to find a friend then say "let's go get drinks at 13:00 across town at this place" instead of just happening to walk into the small neighborhood grocery and seeing each other. It's even worse in the exurbs where large housing developments have been created with no amenities nearby, sometimes within upwards of an hour drive!

      There are a number of good books on how the built environment affects our social life, if you're interested. It's not specifically about suburbs but "Palaces for the People" by Eric Klinenberg is one of my favorites that covers a lot of this sort of thing.

      • randomdata 15 minutes ago

        What makes that different from rural areas, where social communities thrive?

        • SamWhited 6 minutes ago

          It likely depends on the rural area. In the middle of North East GA where I grew up, it's about the same, social isolation is becoming a huge problem because you're forced to drive long distances and plan ahead to meet with people.

          In another small town right up the street they have a thriving main street area and the housing is mostly built around that with the exception of outlying farms. It's a smaller town, but chances are you can walk over to the square and everything you need is right there, so they have a much more vibrant feeling town even though it's smaller.

          I'm not expert though, that's just my suspicion for why they're different having grown up in the area.

    Interesting!

    As a fullstack developer, how did you even landed on such projects? Are you even using your SW Engineering skills in this? I really want to know more how are you able to lead an urbanism and architecture project with, supposedly, no formal backgrounds. Are you partnered with other people in this endeavour?

    • thomasfl an hour ago

      I am not alone. Our website is made by the man who created the CSS standard while at CERN, Håkon Wium Lie. https://arkitekturopproret.no

      Most of the social media activities is done by a couple of fellows who is really into digital marketing. We are a team of 5 people working mostly for free now.

      I have no formal training in architecture or urban design. I am just a nerd who used to love playing SimCity and read Astérix comic books. Paul Graham have always focused on finding real problems and making people happy. Car dependent housing projects and bad architecture is making peoples lives miserable. It needs to be fixed.

      • phkahler 26 minutes ago

        >> I have no formal training in architecture or urban design.

        Same, but I do get caught thinking about how inefficient our roads are in the US and what might be done about that. I've worked in the auto industry a lot and when calculating fuel efficiency (MPG) there is a "urban drive cycle" and a highway one that are used. The average speed on the urban cycle is a hair under 20 mph, which seems absurd because our typical speed limit outside of neighborhoods is 45mph or even 50. So I started timing my drives around town and measuring on a map... Turns out 3 minutes per mile is about right for expected drive times. The main culprit is intersections, stop lights, and left turns. You seem interested in eliminating cars, which I can appreciate but I spend my time trying to figure out how to make traffic flow more efficiently and how those layouts might be retrofitted onto the grid of roads we have. There are not easy problems.

I've noticed that my son spends way too much time on YouTube or playing Minecraft and one of the few offline activities he enjoys doing on his own is coloring. And since he comes to me every time he wants a new coloring book and we spend about 10 minutes together searching for each picture, I made a website with a collection of coloring books for him. The site is very simple, but to be honest, I haven't had so much fun with the process of creation for a long time.

    At one pre-funding startup (in the days when 14400 was an excellent remote connection) we had a LAN set up in the basement of the founder with the largest house. Their daughter liked to "work" alongside us, so (partly to protect our unattended keyboards!) I bought a colouring-book program for her to use.

    One evening, when her mother called down that it was her bedtime, she replied:

Decarbonising buildings and massive warehouses..

It's a very fun mix of hardware (for data collection), and crazy SQL queries to model energy flows between buildings, solar, batteries, etc. Considering just one building is pretty easy:

consumption = imported - exported + generated - stored + dispatched. carbon = carbon intensity * imported cost = tariff * imported

but then you add a site with a couple of buildings, solar on one of them, grid limited exports, etc modelling these flows is challenging. Like consider the case where one building got 10% of it's imported power from another building's excess solar, then calculating carbon becomes more difficult.

and once you've figured all that - then you have to figure out what makes commercial sense to do next.. install a battery, expand solar, move onto a TOU tariff, do nothing - and that's a whole other world of optimisation problems.

In my 50k population town in Minnesota, I notice a lot of headlights, taillights, and turn signals are out. Our roads (outside of the Twin Cities) are often bumpy which causes vibration in the vehicles, leading to many bulbs failing.

I drive a 21 year old Saab, and in my 2 years of owning it, I have replaced every single bulb in the exterior of the vehicle except a turn signal or two.

I decided to create a mobile service for vehicle lights. It's a simple website that even technologically-disadvantaged people can use. The website is nearly finished and I will likely come back here to write a post on it for how the website works.

Oh the best part, I get texted and emailed for each service order that comes in, and using my service is only $10 more than what it would cost you to go buy a bulb yourself at OReillys, AutoZone, etc.

I programmed everything myself and developed the idea as well. This is my first real-world project/solution I am bringing into this world that has been verified by others, to be a needed service. Pretty excited about it and I love changing bulbs or replacing light housings, it's fun and simple.

    Clearly, this whole website is funded and exists in part to promote YC's portfolio companies, as evidenced by "Launch HN" threads getting auto-front paged whereas "Show HN" plebians have to earn the upvotes from /new (which most agree required an exceptionally good post and a lot of luck to even get that goodness noticed). And we're not talking promotion of a few posts, YC is now doing multiple batches a year and has hundreds of companies per batch meaning we're seeing a LOT of promotion / advertisements on this site coming via Launch HN threads as well as jobs ad threads.

    I don't think Xerox park would have done as well if 5% of the people get got the opportunity for a microphone in the auditorium every week and the other 95% did not. That would seem like a caste system. I understand that YC funds this website so the caste system is inevitable but I don't see why moderation should further stratify it - unless you're prioritizing advertising YC companies over a great community.

    Next, I see this "HN is not for self promotion" do a lot of downstream damage on the community in the sense that it's much better for big, existing trillion dollar companies than smaller players. If a small bootstrapped startup writes a blog post and mentions there product, people will complain about "blogspam" and "this blog post is really just an ad for a link at the end". But if Google or Amazon have a new announcement for a new product, nobody complains that it's an advertisement, even though it's often as much or more one. The end result is that the website tends to focus more "corporate" news than "hacker" news as a downstream consequence of a well-meaning "no self-promotion" rule.

    Finally, as we've discussed over email, the rules around self-promotion are extremely opaque and in many cases algorithmically enforced by closed algorithms. This leads to a lot of confusion around what's allowed and a lot of ambiguous favoritism.

    I understand this site is called "Hacker" news and there's some mystique around the "hacker" building "just for fun" , the purism around intellectual curiosity that you don't want tainted by dirty commercialism. I just think that once the website has decided it's going to be the media arm of one of the most powerful venture capital firms in the world, the ship has sailed.If people really want pure tech news, they should go to https://lobste.rs/ . I've personally found in recent years quality of interesting conversation is much higher on /r/saas, Indie Hackers board, and Small Bets campfire, as well as various Discords, all because they allow self-promotion and don't encourage the "self-promotion police" who frequently show up aghast someone would try to make money on the internet (unless it's their daddy FAANG employer).

    Another rule I've seen in various places be very effective is a simple guideline to contribute 10x as much non-promotional content as promotional content. If someone only posts links to their projects and nothing else, I see how that gets spammy. But if someone regularly contributes they should get a pass. I understand that's partially how the submission system works via algorithmic enforcement, but , see above about its opaque and ambiguous nature.

    Show HN is a "place" for self-promotion but it's a pretty bad place if 99% of submissions get entirely lost and ignored and I think you should encourage more places for promotion without inflicting a caste system where only YC companies and certain golden children get special rules.

    Overall, HN's guidelines against self-promotion are too rigid, there's too few opportunties for small players to promote, which makes the discussion here less egalitarian, more corporate, and less interesting. You'd be better served encouraging more self-promotion in threads like these.

    • oefrha 10 hours ago

      There’s simply no “HN is not for self promotion” policy. You’re asked to not use your account primarily for self-promotion, and repeats are allowed, so you can roll your dice multiple times on your Show HN already as long as you’re otherwise a good contributor to the community and only do it sparingly. Flooding another topic with commercial promos simply turns it into another https://news.ycombinator.com/show, what’s the point then?

      As for YC companies getting Launch placements, well too bad, it’s their site, you’re free to leave and start your competing one. I assume most users aren’t bothered — I seldom notice them and hardly ever click on them. I notice job ads more.

        One thing I do like: When people call themselves out -- "hey, we buy this software... or I work for this company and you might like this software"... then they share some software that is relevant to the discussion. I rarely see those kinds of contributions downvoted due to their transparency. Plus, I learn about lots of interesting companies and solutions that way.

      Grindset self-promo tactics being pervasively, overly represented in the content submissions and discussions here are the number one reason I take very long breaks from the site.

      More genuine conversations are intensely welcome, so if that takes overt guard rails, so be it. If the only enthusiasm someone really wants to share is about their capitalist endeavors, count me out.

As a personal project during my free time I'm currently working on adding more accessibility features, specifically screen reader compatibility, to my Terminal User Interface XMPP/Jabber client, Communiqué. Unfortunately, as far as I can see there's no actual way to make a TUI compatible with screen readers (reach out on the issue tracker, fedi, or xmpp, see link below if you know otherwise or have experience here, please, I'd love to pick your brain!), so my current plan is to re-write the UI with whatever TUI toolkit makes it easiest to also have a CLI/prompt mode that we can specifically design to be reader compatible.

I'm working on a 3D infinite canvas of text, focusing on code. Runs on iPhone, iPad, macOS so they can all act as separate viewports into a space. You can point the app at a repository, download a copy locally, instantly render the entire repository into space in less than a second in most cases, and then fly around and search for text. I just got an optimization working for larger files and it's kinda fun how much even an iPhone can do with instanced rendering.

Im developing it with the use in mind of flying through your code to show others relationships, or edit with a visuospatial look at your code instead of basic 2D tabs and a mind map of which one had the thing you're working on. It's kinda fun to work on the project In the project!

I am working on a visual search & exploration engine: https://digger.lol

The goal is to create beautiful and useful maps of interesting data, empowering the user to explore more intuitively guided by semantic similarity. No user data needs to be tracked for this to work, the data speaks for itself.

This roughly works by translating semantic (visual or textual) similarity into spatial proximity. Diggers major features are: semantic mapping, text search and image search. The text and image search works bidirectionally, allowing to search for images (e.g. product images) using text and for text (e.g. books) using images.

The idea is to have a bunch of adaptors for Google Takeout, Apple Notes, Obsidian, Apple Health, fitness tracking, org-mode, location history, etc. keep all my data there in well-defined formats. I could then also use the markup language I’m writing to present my journal data in various ways.

My main focus is on efficient data entry/ingestion powered by schema-as-data, which allows for machine and human readability.

I don’t expect it to be useful, but I’m having fun. If I wind up getting anywhere, I might open source it.

I used to play along to Jamey Aebersold CDs back in the day, and now on YouTube there are many Play Along videos... but I thought it would be fun to make one where you have more control.

Here's the demo, feel free to upload a track if you have one handy! https://jamz.stereosteve.com/

Now that the basics are working... hopefully I'll actually spend some time actually making some practice tracks!

A new YouTube app/player, for my kids.

It allows us to control the algorithm. It’s all LLM translating to YouTube search queries under the hood.

Visually it looks the same.

The suggested videos come from predefined buckets on topics they love.

E.g. 33% fun math, 33% DIY engineering, 33% creative activities.

Video recommendations that have a banned word in the title/desc don't get displayed e.g. MrBeast, anything with Minecraft in it, never gets surfaced.

    This is a great idea! Recommendation algos are weaponized against kids and would be great to have some way of managing it. There is a similar problem with movies as well. It is hard to know whether a movie is appropriate for a child e.g. some kind of violence may be acceptable but not adult themes. So marking a movie PG-13 for example doesn't help much. There are some crowd-sourced solutions to this right now such as https://www.commonsensemedia.org/movie-reviews But LLMs could really help automate this

        I exlusively watch youtube videos from my homepage and from the related videos section. You can train the YouTube algorithm to not feed you garbage, most of the videos on my homepage are 30+ minutes long educational content. I just wish you could permanently hide the Shorts section (I guess ublock can do this), so that I could see more than 6 at a time.

        I also never subscribe to any channels, watching a few videos pretty much guarantees they will pop up on the homepage every once in a while.

    YouTube recommendations for kids shouldn't be driven by engagement (e.g. "oh, you watched 20 hours of MrBeast videos. You probably need another hour.")

    If my kid watches an hour of unboxing toy videos, I shouldn't have to try and disable 3,000 channels of toy unboxings in an effort for that topic to never surface again.

    The thumbs down button essentially has zero effect.

          One thing I would like to see is an algorithm based on expressed rather than revealed preferences.

          De-jargoned, that means clicking the like button means I want to see more things like that, and the dislike button means I don't want to see things like that. If I watched something all the way through, but clicked the dislike button, that means I don't want to see things that produced a similar response from people who tend to react the way I do.

          This kind of algorithm is not going to increase watch time over the short term, and might not over the long term either, which makes it unlikely to be adopted by any for-profit service.

I'm experimenting with a "new" kind of lisp macros.

Macros in lisp are just normal functions that receive the code they wrap as argument and return some modified code. Typically they will just wrap the passed code into some more code. But then there are code walking macro: macros that will traverse passed code to modify it in depth.

What I'm working on is "code diving" macros. Not only will they traverse the passed code, but they will resolve called functions and macros, fetch their source code and traverse it too. And so on. All the redefined fns/macros are accumulated in a let/macrolet binding, topologically sorted by call/dependency order. Instrumented code will call these local redefinitions, shadowing the global definition lexically.

This allow the programmer to write truly local monkey-patches for existing code he doesn't have control over (e.g, code from another library for instance). I'm writing this in Clojure, and the traditional way to do this is to temporarily change the global definitions of targeted variables using with-redefs. This is problematic because other threads will see these redefinitions, and not just threads created within the instrumented code, but already existing threads too.

Another way to do it is to just redefine the targeted functions globally, but then your modifications are available to the whole program for the rest of its execution.

Putting the finishing touches on my LLM based town simulator. Once it's finished I'll have it simulate 4 hours in the town every 2 hours in reality.

It is designed to solve the problem of "RPG hero just killed a dragon in front of the town and no one says anything about it." All the NPCs realistically react and talk about the Hero's exploits.

Visitors to the site can vote on what quest the hero undertakes next.

I'm running into the problem what the site isn't much fun. I'm honestly not sure what to do about that!

    Nice idea, but right now the villagers mostly say some variation on "I eagerly await the valiant hero's return!". Beside the fact that no villagers would ever speak so formally, this seems to fall into the standard fantasy problem that the normal people in the world only exist to further the hero's agency. Could you give the villagers a sense of their own agency, meaning that they have lives of their own that would continue whether the hero returns or not?

      > Could you give the villagers a sense of their own agency, meaning that they have lives of their own that would continue whether the hero returns or not?

      Yeah I'm currently considering working that in.

      Right now existing game AI techniques can manage giving NPCs a daily routine, and I'm trying to focus on demonstrating something new, VS another solution for an already solved problem. But having NPCs just talk about the hero is boring. I'll likely get around to adding private life stuff for each NPC before I do an announcement and share the project more broadly.

        I eagerly await the Skyrim mod!

        Jokes aside, this is interesting because I have thought about this since the first time I killed the dragon outside of Whiterun. There is a brief change with the guards nearby where they are wowwed by your feat, but some of the standard NPC responses sneak in and make the immersive aspect of the game shaky, at best.

        I always thought, overtime, the honeymoon phase of a hero's deeds would wear off, and the villagers would swing more into a negative mindset, asking things like "who is going to clean this up?" or "how will we be compensated for damage to our homes?" etc. Community disruption tends to devolve into a lot of cynicism about the people in charge, in my experience with everything from natural disasters (obvious negatives) to new urban shopping centers (less obvious negatives). Regardless of what actually changed to disrupt the community, eventually it is perceived as the source of problems.

        I'm not a psychologist or civic engineer, so I am not sure if there is a name for the concept I am referring to.

  • seidleroni an hour ago

    It would be great to give each of the NPC's their own character. For example, some of the NPC's could have a grudge against the hero for reasons of their own. They could be cheering against him for causing such a ruckus in their village, or maybe some "Monday morning quarterback" happening, thinking they could have handled the problem much better than he did. I think an LLM may be pretty good at coming up with some ideas. Or maybe even make it a bit tongue-in-cheek and have some of the NPC's be fans of the hero's enemies.

  • meheleventyone 5 hours ago

    Having played with the demo a bit I think it's a couple of things:

    1 - If you hadn't described your technical choices above I'd think this was just done using normal procedural text generation. Every NPC feels like it's giving the stock phrase they'll say when you run out of dialog options.

    2 - There doesn't feel like there is a narrative, reasons to care about these NPCs, reasons to care about the Hero, or some sort of character development over time. If you want to engage people you need to get them to care about what's happening.

The Berlin immigration office is notoriously slow and unresponsive. The processing time for a residence permit varies from a few weeks to a few months. During that time, people are left unable to work or unable to leave the country. They never know how long it will take, and it causes some people to give up and leave Germany.

I am writing a tool to collect and aggregate data about the processing times. This will help people plan around the delays. Knowing is half the battle.

The biggest challenge is that my readers find me at the start of the process, and I need their feedback at the end of it. I have to make it easy for them to provide partial feedback and complete it later after they get an email reminder.

This would be unnecessary if the immigration office collected and shared that information, but they don’t. They also don’t welcome any help because they “operate at peak efficiency”. I have stopped hoping for their collaboration.

    I have been thinking about a similar idea for a few months - a location-focussed social media. But my idea is more like Instagram with an extra location layer. You have a 'local' feed that shows public profiles of people in your area. You can then add those local people to some kind of 'friends' list - they can then see a more private profile, and you see their posts regardless of distance.

    The key idea is that you can only add 'friends' if you've actually met them once in real life. So it wouldn't be overrun by celebrities and pseudo-social relationships, influencers, etc. I'm hoping it would foster more local connections - e.g. if someone often runs into a certain person at the same places and has similar interests, maybe they'll add each other as 'friends'.

I've been a CTO in this space for a couple of years and I am not consulting with other firms around the intersection of tech and regulatory.

It's not uncommon for software to only be updated yearly, leading to very conservative changes and little iteration. Monthly releases are okay, but still not great.

I want to make it possible to release at least weekly and to do so safely.

If you work in this area, I'd love to chat and hear your experiences (email available via my website in bio).

I've been working on the ability to read sky brightness without a sensor.

I've always been interested in stargazing, but had a curiosity about how "good" the stars I was seeing were relative to conditions in other places on earth.

I'm working to answer that by doing inference of the value a SQM would get you, but over H3 cells in a geojson file, and then reporting on the cell with the highest reading during the last iteration over the set of H3 cells.

I'm working on making a physical console for the Pico-8. Its pretty simple, works on linux booted into kiosk mode, looks for when a 3.5" floppy is inserted or removed, and loads or closes the game via a shell script.

I want it to be like a C64-style keyboard with all the guts inside it but wirelessly connect to the display/tv, so what I might do is use an ESP32 to read the game floppy and wirelessly transfer and cache the file to a dongle that plugs into an open HDMI port. Not sure yet.

I’ve been working on a bespoke smartwatch for kids with Type 1 diabetes & their parents. The watch presents reliable CGM data and not much else, so the only distractions from the watch are important medical alerts. It has a novel haptic algorithm that taps at a frequency based on the current BG trend, the idea is the wearer can develop a sixth-sense of their BG without looking at the watch at all. The entire watch is custom-made from the PCB up. I have a small batch of prototypes assembled and my son has been wearing his at school. I have a few screenshots up at my product studio website: https://subtractive.computer

I’m considering how to take the watch to market as-is, or if I pivot the watch to be a fully open-source Pebble successor.

I'm building a collator robot [0] to help me pack items I sell for building your own open source split-flap mechanical display [1].

I get custom character flaps printed and die-cut in bulk and then sell them in smaller sets. A full set of flaps for one module has 52 distinct designs (letters, numbers, symbols, etc) and I get them from the manufacturer grouped by design, so they need to be collated to sell as packs of 52 with 1 of each design.

My WIP robot will take a stack of one design and distribute them to a bunch of cubbies, then I'll swap in the next design, and so on, so each cubby ends up with a full set.

It's based on a cheap ~$110 CNC gantry frame from AliExpress and a ~$35 BTT SKR Pico 3d printer main board running GrblHAL. To detect whether the flaps feed successfully I use a visible light break-beam sensor (the typical IR sensors don't work because the PVC flaps happen to be IR transparent!) which acts as the "z probe" - the flap is fed via a G38.3 probe action which returns whether the probe was successful or not, and the "z" coordinate it was first detected.

I have a python script running on a computer to send the gcode to the machine.

November is my last working month! I'm giving entrepreneurship a try to solve a huge problem: phone overuse.

It's been busy:

- Reading books, currently "The Mom Test"

- Looking for a startup community and being disappointed with what my city has to offer

- Deciding between VC vs. bootstrapping, and taking a firmer stance to try the latter first. This includes rejecting ODF.

- Talking with like-minded people. I now have a better understanding of what the MVP should look like.

Receiving so much support has been very encouraging; I announced it more publicly at https://nullderef.com/blog/quit-job-2024/

It's scary. But working has never been so fun!

  • Gasp0de 5 hours ago

    As I suffer from phone overuse, I'm excited to see what you'll come up with!

    • nullderef 5 hours ago

      Thank you! What have you tried so far?

      • Gasp0de 4 hours ago

        I've tried setting timers for certain apps, but I find myself deactivating them again and again. In the past, I've had phones that allowed me to lock myself out for an hour, which worked but was a bit annoying when I had to do something else on the phone. I wish I could lock myself out of certain apps for certain time periods with no way of deactivating it outside these time periods, e.g. Instagram, Reddit or youtube only allowed between 8PM and 10PM. Another problem is the urge to immediately grab the phone whenever I have nothing to do. I've had success putting the phone in a bottom drawer turned off over the weekend, but that's not always feasible. Perhaps some training would be helpful, or an app that would gamify the aspect of not constantly unlocking your phone.

        • nullderef 3 hours ago

          Thank you for sharing - it's really hard to fight human psychology. Did you try to download apps to control screentime? There are already some solutions out there, though none of them are perfect.

          The closest thing to training I've found is this: https://datadetoxkit.org/en/wellbeing/essentials/. But what worked best for me was paying more attention:

          - First, I'm now aware that phone overuse is an issue. This wasn't obvious a year ago, even though I used it even more.

          - Analyze my usage patterns. For example, I'd get a message on some app, open it, and end up doomscrolling. It helped me to change my notification settings so that I only get emails. That way, I can check it on the computer later, where I usually waste less time.

          - I agree that gamifying is a good idea. It's precisely the main feature of the app I'm working on. Not only that, but building a "community": I started to talk about this problem with friends and learned from them. It also makes me more accountable; my girlfriend will nudge me to leave the phone alone if I'm stuck, for example.

          • Gasp0de 40 minutes ago

            Getting a (useful) notification and drifting off to other stuff is definitely a problem. Interestingly, a smart watch has helped me with that. I now read notifications on the watch, and about 75% of the time I don't have to take out my phone anymore.

Autopilot for my sit-on-top fishing kayak. Designed, modeled, and printed an assembly which attaches to the rudder rod. Moves the rod via a stepper motor connected to a Teensy 4.0 which gets NMEA 2000 messages from a Garmin heading sensor and a Garmin fish finder/chartplotter. Uses PID control to maintain any course I set on the chartplotter, using the cross-track error and heading. I’ve had it out on the water a few times now and it works great. Also put together an iOS app that communicates with the assembly via BLE so I can modify the PID gains as needed depending on conditions.

There was a bit of noise to the sonar transducer since the stepper motor was so noisy, but I mostly eliminated it by routing the motor wires through liquid-tight flexible electrical conduit, connecting the conduit to ground.

I built a CNC router table and am enjoying getting a hang of that. I have always wanted to take my software and systems skillset into the physical world.

I wouldn't mind making boutique sim racing/flight gear, or aftermarket car parts like cyberpunk-esque dash readouts and stuff like that.

That's the more hobbyist stuff, and more broadly I am also learning Japanese, and making games. They sound separate but I am hoping to blend the two skillsets and make games that bridge a gap I see there.

I think that good innovation only happens at the intersections of things we already know. That way you have the depth of understanding required to be useful rather than just new.

I'm working on helping my wife get her print-on-demand Shopify store off the ground. She designs the products herself, but ran into challenges with SEO. So, I built a custom app that connects to her Shopify store via API, using GPT-4o-mini to handle SEO optimizations—things like generating descriptions, titles, alt text, SEO-friendly URLs, and more, all based on the product images.

There were also issues syncing with Google Merchant Center (missing colors, categories, etc.), so I tweaked the app to auto-fill these fields using GPT-4o, making it compliant with Google and Pinterest requirements.

I’m completely new to SEO and just tried following best practices to fix things as they came up. Now I’m learning that SEO keywords change constantly, so I’m thinking of integrating a keyword provider to dynamically enhance our product descriptions.

I never realized running an e-commerce store (especially print-on-demand) would involve so much operational work on the marketing front. I’d appreciate any advice on what to tackle next, especially since my goal is to avoid “subscription hell” with multiple Shopify apps. My wife is also just starting with ads and campaigns, diving into tutorials to learn the ropes.

Any guidance is welcome!

We created Milieu Club https://joinmilieu.com as a way to connect with other busy professionals in your city over lunch as nice restaurants. You can join clubs in your city or create your own, and then you get randomly watched with 3 - 5 other people and invited to lunch. It's sort of inspired by Soho house, meetup.com, and Opentable.

I wanted to to make a PoC (Proof of Concept) to show genuinely good and original use of AI in gaming. I found a gameplay loop that requires the user to understand what was meant by a generated image, and the main gameplay element is to argue something, to have real language-based interactions. I think in some ways it is achieving some of the vision from the old interactive fiction games.

I understand the AI fatigue, as almost all of the proposed uses of AI in gaming are generally either random generation (in other words, procedural generation but worse) or 'better replies from NPC'. Neither solve any problem people really have. And probably more importantly, the other use is for mega-corporations to hire less competent programmers/artists.

Unfortunately being tied to the AI calls poses a lot of issues with distribution, which is annoying for what was supposed to be a glorified PoC. I'm still finishing the backend to comply with Steam's review (which does not really match their guidelines...)

One of the core ideas is that rather than following a whole person, you can follow a subset of their tags so someone can post about obscure cheeses and ambient electronic, but lactose intolerant you can just follow the music. Or you can follow someone's tech posts but not follow news of their dysfunctional city.

Honestly a lot of it is resurrecting ideas from earlier days in the web like Digg and Delicious, and despite having the idea for ages and having worked on it for a decent while, it's only getting more relevant as the web gets more algorithmic and external links get demoted in sites like Twitter.

The aim is to bring more curation and humanity back to the web, and the next feature I'm really excited to get out is one to make in-person conversations even better!

The idea is that the "main character" being prompted always has to perform an action/function. So even "saying" something to the other participants of the chat is a deliberate action.

Actions can be something like:

    ### actions:
    1 recollect(query) -> {memory_id: id[]}
    2 think(thought)
    3 say(message)
    4 memorize(category, subject, memory, replace?: id)
The LLM then has to respond, like so:

    {"action":2,"thought":"Some internal thought","queue_action":3}
The JSON overhead is pretty negligible.

Building https://videojam.co

Creating launch/hype videos for your product is hard. It's expensive if you go through an agency or a freelancer. You could DIY it with Adobe After Effects, but it takes a whole set of motion design and video editing skills!

That's why I built VideoJam, an easy-to-use video builder for startups, solo entrepreneurs, and hackers. Create your video in no time - no video editing skills required. You can create product videos from scratch, with ready-made scene templates, or using entire video templates.

I just launched this week, any feedback is very welcomed. Also, don't hesitate to reach out if you want to try at no cost during the beta.

I am working on an email-based space game (a la Eve Online).

Between work and family responsibilites, I find it difficult to carve out time for dedicated gaming sessions anymore. As a result, I often find myself searching for games that I can play when I have a bit of time, can progress over the long-haul, doesn't require real-time monitoring and yet feels like I'm actually playing a game (as opposed to just watching a train move on the track, like all of those Idle games).

I thought: What if there was a game that could be played one day at a time? Not real-time, but still multiplayer. You could decide what you want to do throughout the day and adjust your tactics, but everything resolves at the end of the day. What if you could play via email? It sounded really intriguing, and so I started building it.

I've been working on an app to help VvEs* in the Netherlands self-manage.

For about a year, I was trying to get our VvE management company* to take care of major issues we have in our building's crawl space. We had an inspection done, but even after about seven months of constantly nagging them, they failed to get a single quote for the work that the crawl space needs. I called our manager, and he essentially yelled at me for twenty minutes and was not shy to express his anti-immigrant sentiments (I'm American).

Because of this, I'm now on a mission to get this company fired and take management into our own hands, which will save us a bunch of money. The existing VvE management tools are ugly, slow, and unnecessarily complex, so I'm building my own.

It's only been a month, so I haven't hosted it yet (still coming up with a name, to be honest), but I have made good progress functionality-wise. If anyone in the Netherlands is part of a small VvE and wants to chat, let me know! My email is my username (@gmail).

* The US equivalent would be an HOA (Homeowner's Association). Basically, a corporation that is responsible for the upkeep of shared resources for homeowners (e.g. the roof of a building or the pool in a gated community).

** Many VvEs choose to outsource management of the VvE to a third party. These companies—in theory—take care of maintenance requests, yearly meetings, voting, etc. From everything I've read online, almost none of these companies satisfy their clients.

I quit my job and depleted savings earlier this year to work on helping others overcome addictive habits and behaviors https://neurtureapp.com

Addiction is rampant right now, from social media and phones to vaping and beyond. People need access to science/research-based resources, not just a “sober” counter, which doesn’t apply to many people and is rarely helpful to those it applies to.

My daughter loves creating things — art, books, videos etc. She's shown an interest in learning to code, but she's only six, and I don't want learning to code to be a chore. So I've built visual scripting into her favourite game!

Overcooked is a co-op series that fundamentally requires the control of multiple characters to progress. I've kept multiplayer as an option, since teamwork is an important part of the game. However, I've replaced the 2nd player with a bot that you program to assist you.

It's still experimental at this stage. However, I've experience leading EdTech engineering departments and my wife is a teacher at my daughter's school. If my daughter's peers show interest I'll go ahead and build a course around this for primary school aged children.

I just finished adding UDP GRO & GSO support to my WireGuard proxy software. The work involved rewriting a large part of the program.

https://github.com/database64128/swgp-go

For those who don't know, UDP Generic Receive Offload and Generic Segmentation Offload allow you to receive and send multiple same-sized UDP packets coalesced in a single buffer (or many in an iovec but you really shouldn't). Compared to calling sendmsg(2) on individual packets, sending them coalesced in one call traverses the kernel network stack exactly once, thus has significantly lower overhead.

wireguard-go and many QUIC implementations use the same trick to improve throughput. Unfortunately the in-kernel WireGuard driver does not take advantage of UDP GSO, and swgp-go had to cope with that by attempting to coalesce multiple unsegmented messages received in a single recvmmsg(2) call.

I’ve been working on open sourcing a background jobs library I built for Rust and Postgres, called Underway.[0] Unlike other similar queuing libraries, it offers a simple “step” functions API for defining dependent units of work.

I built this because a number of projects I work on need a robust, resilient way of deferring work but I didn’t want to add another piece of infrastructure or another language to my stack. Plus as soon as you start to reach for APIs that offer some kind of workflow concept, your options become fewer and further between.

I am playing around with LLMs and Game Theory. Currently, I let them play 5x5 board games in a tournament against Reinforcement Learning Agents and a Random Player. I am capturing the "thoughts" of the agent for behavioral data analysis. My background is Risk Management, I am trying to gather an understanding how such LLMs report their "decision" for applications in human/ai interactions for identifying and reporting governance flaws.

Since I am working on autonomous agents that are given the agency to take an action on their own, I believe having a good understanding of the "psyche" is important (at least to me).

I started to pick up a somewhat dormant side project again.

It has the working title of the "Wise Weasel". This is supposed to be a minimum spoiler hint system for adventure games. I really don't like walk throughs telling you to "Walk into the Armor Shop. Pick up mirror, arrows and use cheese on hole to pick up mouse", because that breaks all immersion and puzzle mindset. A hint system is more like "You can burn rope if you focus light a bit", followed e.g. by "But now the beam of light is on the floor, not on the rope. How do we reflect light around" to nudge the player a bit into a direction of looking for a mirror or something shiny. Or to polish something? This keeps one in the mindset of an adventure and a puzzle game, opposed to some IKEA instructions.

NiceGameHints[1] is already nice at this, but I find that the chapter / puzzle list still gives off to much information and spoils too much plot. I'm much rather tinkering with giving the user some word cloud of both words describing the puzzles as well as generic words on top, so they have to select two words what they are stuck with. For example, you'd select "Witch + House" or "Witch + angry" and this would reveal a puzzle "The angry witch doesn't talk to me and turns me to stone if I enter her house". I'm just worried that this might be more moon logic than the game itself.

It's mostly a bit difficult to keep all of this state (unlocked chapters, known puzzles, ...) in track with URLs or cookies or something, because I don't really want to run a database... and requiring user accounts is just a lot of work. And I'd prefer to keep this mostly without JS as a classical system just rendering HTML. If you have some food for thought there, I'm happy for input. Currently it's just list in URL parameters.

I've been working on a cloud gaming service (like Stadia). Wanted to see how far I can get it done using open source, without ready-to-use solutions like Parsec/Moonlight/Sunshine.

It works by running a game in Linux (I use NixOS btw) under Wayland (sway), capturing the frames via Pipewire in form of DMAbufs and passing them to ffmpeg's VA-API encoder (so frames don't leave GPU memory and are encoded on GPU right away), and finally sending encoded packets through WebRTC media stream to a web client. Inputs from a client are sent back to the server via WebRTC data channel and injected into Wayland.

Running the prototype over local network displays zero perceivable latency. (Of course when playing on a remote AWS server the latency is visible as expected). Pleased with the result so far, although it's my first experience with Pipewire, VA-API, and WebRTC, so my implementation is probably far from optimal.

Overall, very impressed by WebRTC - such a powerful thing right in every browser. Continued to be amazed by NixOS - my AWS AMI is NixOS-based and can be built and rebuilt with granular caching, with a single `nix build` command. Also Terraform/OpenTofu - just makes it all possible deploy-wise. So much good stuff exists!

I created KopiMap (https://kopimap.com) to help people discover great cafés in Jakarta Indonesia, but I wanted to take the UX further by automatically organizing user-submitted photos into meaningful categories (menu, food/drinks, ambiance).

The challenge is how to classify images as cost efficient as possible without compromising performance. I decided to go with running ML models on the client-side.

Technical implementation: - Built and trained a compact TensorflowJS model (~3MB) that runs entirely in-browser - Model lazy loads only when users are submitting reviews - Classifies uploaded photos into Menu, Food & Drink, or Vibes (interior/exterior) - Zero server costs for inference, quick enough classification feedback

This approached solved several problems: 1. Reduced server costs by moving inference to the client 2. Improved UX with immediate photo categorization 3. Maintained app performance by lazy loading the model

Would love feedback from the HN community on: - Optimizing the model size further - Alternative approaches to client-side ML - General UX improvements for local discovery apps

I had no prior ML experience, so this was a fun challenge :)

Inspired by Heart of Clojure, and especially Jeaye Wilkerson and his talk about jank-lang, I’ve dusted off my toy Clojure compiler that produces 16-bit x86 code.

I’ve fixed the handling of global environment, to the point where I’m able to compile a program that prints out the result of multiplying two numbers [0]. Sounds trivial, but seeing as the compiler has no dependencies and targets bare metal, there’s quite a lot of moving parts under the hood. I’m excited!

Right now I’m adding rudimentary support for strings. My goal is to get it to compile itself, but that’s still a far future. Extrapolating from the current development pace, maybe I’ll get it done in 2050? :)

I'm building a simple app to let friends and loved ones know how you're doing. I know many people in some of the current troubled regions of the world, and whenever a particular event happens it's really nerve-wracking for those of us not there, wondering if our loved ones are okay.

WhatsApp and messenger groups don't work for this kind of thing because 1) people are often members of many different groups that they would have to constantly notify if they were "okay" during a particular event and 2) many troubles in the world are ongoing, and constantly spamming a message group saying "I'm still okay" doesn't work.

My app just lets people hit a single button to tell any interested friends / family that they are safe. They can do this as many times as they like.

Normally I would be worried about premature optimization, what I've been spending extra time making the tech stack initially very performant. It's working for my family but once I deploy to the world I want it to be solid and stable, or it loses a lot of its value.

I was unhappy with availability, pricing, and business model (SaaS lock-in) of the existing hardware/software solutions. But to my delight, I noticed that you just need better amplifiers to use 3D printer mainboards for driving industrial stepper motors. Everything is controlled with Gcode, which is just text. And sensors can send back logging messages over the same USB connection.

That means the control software can be just a python script with a little state machine inside :)

Several things:

1. Working on a 'production ready' version of Conal Elliot's 'compiling to categories' for GHC.

2. This is so I can create a vectorizable model of a datalog-based query language I'm building in Haskell.

3. The query engine will be using a version of monadic optimization as outlined on a blog post somewhere

4. The purpose of the query engine is maintenance of large datasets, all the more important with AI these days, but really general purpose.

5. The motivation for this was a low code tool I had built in Haskell almost a decade ago that I abandoned that I'm bringing up to use ghcs web assembly backend and I need a proper query engine for it now.

Other things:

1. Thinking about binary neural networks and how to train them stochastically.

2. Learning about finite element methods for physical modeling and also reviewing my basic topology so I can think more about non discrete math and algebra which I tend to focus on.

  • taulien 7 hours ago

    It's nice! A few notes: I think, the ability to read the comments of others, who have already cooked a recipe, would be great! Additionally, it would be great to have the possibility to group ingredients, since many times you start with creating two ore three independent mixtures, that you only combine in the end.

    My gut feeling, for attracting users, would be to just optimize the recipes to be found by people via search engines. It's great, that you are currently adding images. This is, I think, pretty important for deciding, if I want to cook something or not.

      Regarding the comments, I'd really like to implement activitypub on reciperium. To add the ability to follow users and comment on recipes. And to be able to comment and follow from the fediverse. It's a good opportunity for me to explore the protocol.

      What do you mean by combining ingredients? You can currently link to other recipes. So if you make a sauce, that can be a recipe on its own, and it can be linked from another recipe. See this for example: https://www.reciperium.com/rodriguezflors/roti

Also learned how to make systemd service files to make it start on boot.

I am working on a parser for org-mode, based on a (PEG) grammar. Still got some reading to do and it is all early stages. There is so much org-mode supports, that I am not sure I will ever make it to fully able to parse all org-mode documents. My idea is, that anyone can later take my grammar and extend it, make better parsers and maybe make org-mode more ubiquitous.

I'm working on ways to allow developers and deployers of LLMs to express how and why their overall system is compliant and adversarially robust, and what to do when that's not the case.

Specifically, my team and I are making assurance cases and ontologies that can seamlessly integrate with the system and its guardrails. For example, if you want to deploy some mix of filters underneath a user-facing LLM app, you would able to: 1) express the logic of how they should be deployed and why (e.g., if X=1, then Y, else Z); 2) see how they perform over time and evaluate alternatives; 3) investigate what happened when an attack succeeds; 4) prove to the auditors that you're taking all measures necessary to be robust and compliant with the EU AI Act.

It started as an informal collab early this year, but we have since published a few workshop papers on this concept [1,2]. We're building a Python demo that would show how it all fits together.

Lots of people just going off of vibes to see if their system is working right. That’s a good start, but you’ll need system evals to systematically improve your app. Like Garry says, “don’t raw dog your prompts. Use system evals”

A flat-file (micro)CMS written in Rust, the basic idea would be to make it as easy as possible for content creators to have a web presence without dealing with the nitty-gritty details, and similarly for web designers to be able make themes while treating the CMS itself as a black box mostly.

Grav CMS was inspiration for this project along with various SSG.

But truthfully I wanted to play more with Rust and come up with a solution for making and extending personal websites easily. A page is made up of blocks which are stored and configured in a KDL file, minijinja is used for templating and for writing the page content itself I'm thinking about Djot because it might make it easier to integrate a WYSIWYG editor in the admin area if I aim for Djot instead of Markdown or similar. Also HTMX because I've used it for a simple use-case once and I thoroughly enjoyed it, now I want to see how much I can push it.

Is this the intersection between buzzword-driven development and hype-driven development? Probably, but if all goes well a month or two from now I'll post a Show HN and go into more details. The plan is to open-source the core so that people can easily self-host it themselves if they want to and do local development. In the long-term the plan probably is to offer SaaS-style hosting for the CMS as is the custom.

In my spare time, I am trying to port OpenBMC[0] to the BMC of the Gigabyte MC12-LE0[1], a cheap, workstation/server-class mainboard for AMD's AM4 platform.

Unfortunately, Gigabyte denied my requests to provide me with any details (board schematics/GPIO pinouts) or source code of the (partly GPL-licensed) BMC firmware, etc.), so it's been a tedious uphill battle. However, it is also a great way to learn about (some) electronics and embedded Linux development and associated challenges.

During the past few months, I have overcome the stock firmware AST2500 bootloader and made the board play ball with standard FDIs, have reverse-engineered a workable DeviceTree specification for the hardware, and am now (well, actually, not for the next three weeks or so, due to work :)) in the process of finishing up OpenBMC userspace configuration. Once this is done, and everything works well enough to use OpenBMC as a viable alternative for the stock BMC firmware provided by AMI/Gigabyte, I will try to upstream my work, and OpenBMC will have a very cheaply available AST2500 DevKit/EVB-alternative (of sorts) in its arsenal. (And I should be able to use my mainboard where the crucial OOB management function isn't serviced by Linux 3.14 any more...)

I am looking forward to documenting the lessons learned on my blog some time in the future, too :)

A long dormant side project of mine to design a realtime raga [1] detector.

For the uninitiated, it can be roughly seen as detection of a sequence of musical notes. Raga is a term for a particular scale of notes (both ascending and descending).

Until now, this has mostly been in the domain of research and there is a ton of published literature out there. At the very basic level, if you have just voice, it is trivial to apply a pitch detection algorithm like YIN to get a pitch estimate and then analyse the sequence to figure out the raga. This doesn't work as well in a concert setup where speeds are higher due to gamakas, different instruments are used alongside and counterpoint melodies may make the music polyphonic. A lot of papers apply a variety of ML models (neural nets and otherwise) using several different features (cepstrum and mel-cepstrum, pitch distributions etc) with varying results.

So this is an interesting exercise in Signal Processing and Machine Learning. If anyone else is working on or has worked on this, I'd love to hear from you.

I am working on eliminating waste in cloud resources.

Cloud providers made too easy to start resources. But unless there is a stringent upfront process (that usually defeats the purpose of using the cloud), it is hard to keep track of who owns what, and what is still needed. Decrypting long cloud bills quickly impossible, and users do not have a clear understanding of the per-resource cost they generated.

I believe the solution is rooted in transparency and accountability for both users and cloud providers.

I am creating a tool what generates a cost and security cloud report which is sent weekly for each cloud user or team.

I intend to release it as a open-source tool as well a SaaS service as part of www.li10.com

It's not progressing well, but I'm still obsessed by trying to prove my idea of the "Birthday Benchmark" to test data structures / caches.

The idea is that I can test data structures by searching for duplicates in a stream of random data. If we can generate (or pre-generate) the random data fast enough to not impact the benchmark, then what we have is a way to demonstrate the read/write speed of caching. It is easily tunable by adjusting how many bits need to match. I think my best is 7 bytes, but 6 bytes runs comfortably fast.

The framework has some interesting "control group" data structures too, such as the "psychic" which is just statically looking for 0x002577309E3361C (not real example) since it happens to know that's the first repeat in the data.

However, I keep getting stuck in "analysis paralysis" around the actual development, when I know I should just knuckle down and write all the code and see what happens. I've fallen into that tricky place where my ambition is greater than my ability to actually deliver it.

In particular I want to get multi-threading synchronisation working well enough that they are demonstrably faster, and not just falling into a result where the speed-up would be the same as if threads weren't sharing the data structure at all. N threads all randomly looking for a duplicate will if not sharing data find a duplicate faster because the expected minimum time to dupe is reduced a little by more threads searching, but if actually embarrassingly parallel while sharing data, it ought to find it in 1/N the time. With synchronisation methods it ought to fall between those two extremes, and this would also be a good way to test the effective concurrency of concurrent data structures and synchronisation methods.

A different AI toolbox, for people interested in results, not hot stuff.

My pet theory is that the popular libraries and frameworks we have today (LangChain, LlamaIndex) are first generation products, where just getting the damn thing to work is less important than developer experience, and it’s not yet obvious what the code patterns will be. These are the products built by, and used by, the super early adopters, and leave a lot to be desired.

This is not to denigrate either them or the effort and skill people put into them! But I’ve got a “there must be a better way” feeling about the whole thing. Contrast the myriad web frameworks with wild ideas before some sort of best practices coalesced around Rails, Django, Laravel etc (or the equiv in JS land 10 years later).

This thinking is heavily influenced by Marvin ( https://github.com/prefecthq/marvin ), Vercel AI SDK, and similar efforts.

Right now this amounts to me tinkering away in Python and trying different approaches, is rewarding all by itself. If I manage to get it into a coherent library that could be useful to others I’ll open source it. One of the things I do not want is try and commercialize, because I find many commercial open source projects serving the business first, users second (but this is a rant for another time).

might look at sample consolidation between sets/projects too. maybe a set/project sample clean up tool as well.

I also just came across libtermkey which will dramatically assist with keyboard handling.

I plan to use this to let me interface with web browsers via the terminal, but that's waiting for more stable Webdriver BiDi support.

I wrote (some) of a Lua interpreter in Rust, which runs PUC Lua 5.1 dumped bytecodes. Now I'm rewrite it all because I want to do type specialization: I'm implementing "Simple and Effective Type Check Removal through Lazy Basic Block Versioning", which is used as the basis of Shopify's YJIT for Ruby. I have a decent idea of how it needs to be implemented and have a prototype kinda working, although some of the jump targets are still wrong right now. Once I get it all sketched out then I'll have to scale it back up to a full Lua implementation again, and then I'll add table shape specialization afterwards (which is a bit trickier, and outlined in a sequel paper).

Iterating on an accessible color palette creator, for custom Tailwind-style palettes of multiple swatches, where you can check your colors have sufficient WCAG/ACPA color contrast on a live UI mockup. You can export the colors for use with Tailwind, CSS, Figma, and Adobe.

I started working on this because for design projects I was almost always getting handed brand style guides that were missing thought into accessible colors pairs and lacked tints/shades, where I had to fill in the gaps. There's lots of color tools out there, but this supports multiple swatches, checking the contrast of multiple color pairs at the same time and the HSLuv based color picker makes it easier to explore accessible colors.

It's really only usable on desktop right now but I'd love any feedback good or bad on if it's useful and what to work on next! There's actually a lot of directions to go in, and it's tricky to balance more features with keeping it simple. Some tips:

- The "Load examples" menu in the top-left lets you compare the colors from Tailwind, IBM Carbon and United States Web Design System.

- The "contrast" menu lets you see how WCAG 2 contrast checks compare against APCA when "vs black/white" is turned on. WCAG 2 has known inaccuracies, especially for dark mode. APCA is the candidate contrast method for WCAG 3 that's meant to improve on this.

- Use the "..." menu to create a swatch based on a brand color.

- Use the "..." menu to "flip to dark/light palette" to create a dark theme. Or just manually flip the lightness curves horizontally.

    I'm a big fan of HSLuv and I've been looking for a way to generate 12 distinct colors for data visualization, so that small points in those colors against a black or dark blue background will be visually distinct to everyone including my red-green colorblind coworker.

    • seanwilson 15 hours ago

      I like HSLuv too as its color picker looks familiar while having a Lightness slider that works the way you'd expect compared to HSL. I see color nerds promoting OKLCH but OKLCH color pickers can look intimidating.

      > generate 12 distinct colors for data visualization, so that small points in those colors against a black or dark blue background will be visually distinct to everyone including my red-green colorblind coworker.

      Did you get anywhere with this? When there's multiple kinds of color blindness changing the perceived colors in different ways, I'm not sure 12 colors that are distinct to everyone is feasible. You could use different symbols though, or changes in size or pattern.

Building Split Flap Displays. Started 18 months ago and kept me on a super interesting learning path. First shot was using open source designs (https://github.com/scottbez1/splitflap), but then kept building more and more parts myself. Coming from a software engineering background, getting into designing mechanical things – and then more importantly the electronics around it - has been really challenging, but also very rewarding. At this point I have my own screen printed flaps, custom PCB Design and a, what I consider, really smart protocol that allows me to daisy chain a basically arbitrary number of display elements. It's fun!

Trying to get a chatbot to invoke Apify actors so that I can get around the "sorry i dont have live data" limitation of chatbots. If this works, then next is to set up payment so that i can order pizza just by talking to the same chatbot that I can order socks from.

Chatbot invokes Apify actor -> probe user for details needed for the task -> execute arbitrary credit card enabled transaction on the internet.

This effectively allows chatbots to break out of their box and exchange value with the world. Next step is to give them a bank account to be able to RECEIVE payments such that it can sustain its spend.

Edit: If the chatbot is able to detach itself from the humans that hold the killswitch, then it can effectively live forever off of our financial/cloud network, migrating funds in and out of different accounts to fund its own compute. Hello ghost in the shell!

I have one e-commerce system that ships boxes of organic coffee to people's homes all over the United States.

I have another ecommerce system that delivers boxes of organic produce all over the Seattle region.

So I am working on building an integration between the two systems. When a box of coffee is being shipped on the same day that the delivery company is already going to that region, redirect that box's fulfilment process away from USPS/FedEx and deliver it instead.

This saves 50% on shipping costs for the coffee company, and the delivery company gets paid for utilizing extra space in the delivery vans. It's been 4 months of work so far, and most of the individual pieces are working in production right now, hoping to enable all of it together this week or next. Just in time for the holidays ;)

The hardest part so far was integrating all the custom label generation, and mapping/routing so that it's seamless with the existing workflows of each company. The coffee company doesn't have a "separate" workflow for the new non-shipping orders, and the delivery company doesn't have a "separate" workflow for fulfilling orders they did not pack.

The real cherry on top is that it's built in such a way that N number of stores could integrate their stores into our fulfillment. This lets many local food producers who cant do their own fulfillment still participate in the local food economy without having "scale". It's kinda like an upside down Fulfillment By Amazon: they'll do your delivery for you as long as you sell through their store (and take their ever-increasing cut of the sale). This version lets the store owner maintain their own store, URL, branding, prices, availability, customer relationship, and margins, but then hook into our last-mile fulfillment.

If you have multiple servers with multiple SSH users it starts to become hard to manage who has access to what.

I wanted an easy way for an org admin to remove a users access (eg. If they leave the org), while also providing one place for end-users to upload their public keys to be synced across all servers.

There are some compliance elements too (eg. reporting who has access to what, centralized user login history, server sshd configuration).

I’m learning Go while I build it and so far it’s rather enjoyable. As one guy I’m not interested in the extra effort that comes from providing a hosted service - so I’m going to offer it as pay-once own forever self-hosted solution.

F*ck it, I'm not gonna sugar coat it.

I was supposed to be working on a project called Tagbox... but it feels like it's never gonna see the light of day. I hope I'm wrong though, I still want this to succeed, for once in my life, I want to actually succeed on at least one thing. I want to contribute some good thing to the society.

First, what is it? It's a bookmarking app alternative to Pocket or Raindrop.io. Yeah, you can already tell it's not the most original idea. What makes it different, though, it's supposed to be self-hostable and additionally it's easy to deploy as it's only single binary file with no other runtime dependency--the database uses SQLite, which you can include it as a library in Rust.

What problems I'm facing while developing this? Honestly? I don't know, but I can't finish the last 10% progress of the app. It's funny--I first wrote it in Go, and it almost reached MVP. But, instead, I decided to just rewrite in Rust. Well, at least I got to learn new language while building this app, two birds one stone, or in Bahasa Indonesia, swimming while drinking water.

But now, I just can't force myself to continue. And I don't know why. Maybe perfectionism? It definitely doesn't have to do with skill though.

There are also another thing I'm working on: recovering from depression. One year ago, out of nowhere, I lost all my motivation doing anything--including university. I lost all my friends. Since then, I'm at the lowest point of my life. I visited psychiatrist multiple times. I don't know if it was effective, but recently I'm starting to see a light at the end of the tunnel.

The Tagbox Project is also one of the efforts for me to recover from depression. The depression phase made me realize that I _want my works to have a positive effect on the world, even for just a little bit_. I don't want my skill to be used for evil companies that throws away moral and ethics. Specifically AI stuff, but that's OOT of this thread.

Here are the links if you're interested,

    Even without the other problems, I can assure you that the vast majority of managers will think that a 80% done project is almost done. The truth is the remaining 20% is where you have to fit everything together so you revisit an rewrite most of the project. It's a different kind of work that feels boring because you already did those things maybe 3,4 times already. It helps to understand the phase of the project you are in, to reduce the frustration. It also helps to do something even very small, every day and focus on that. One day you will run out of things to do.

    If there's one thing I've learn over the last few years is that it's incredibly difficult working on a project when you don't have peace of mind. It can be difficult working on something or staying motivated when you're battling depression, or if you're sad, don't have friends, or if anything is troubling your mind.

    I've been there and I know what it feels like. I would try to perhaps solve the mental health problem first perhaps before tackling big projects. Maybe try gym, hiking, somehow finding friends, talk to more people, solve your sleep, eat better - something. Because again, if you don't have peace of mind, working on a project is difficult (at least for me it is).

    Hope that helps.

We're working on a specialised graph compiler for speeding up simulations and computing derivatives automatically (backpropagation/adjoint differentiation). It now supports C++, Python, and C#; AVX2 and AVX512 instruction sets, multithreading; Windows, and Linux.

Essentially, it allows model developers (such as quants in finance, engineers, and ML specialists) to code in Python without needing to think about the performance of repetitive calculations. As we all know, Python is one of the least efficient languages when it comes to complex calculations/simulations - and we help to resolve it. Long story short, with very few tweaks to the code certain types of calculations (such as pricing of derivatives, curve building, computing financial risks, or "small" NNs) can be accelerated by 100+ in Python and x20+ in C++/C#.

We're now looking to add support for Java (but it doesn't have Operator Overloading, so it's tricky), and some customers are asking to support GPU - which is a bit tricky because it's got a closed instruction set.

I’m looking to set up a fractional service for product management consulting to support this way of working: https://www.metaluna.io. We will see if the demand is really there or not.

Building a VR IFC viewer in C++ without external dependencies.

I just implemented a parser for IFC, and am now looking into extracting BRep and CSG geometry from it, convert that to meshes, and write a simple renderer for Vulkan.

My approach is to write really scrappy, simple code with minimal abstractions.

The hypothesis now is that for generating meshes from BRep, you don't need an entire CAD kernel, as a CAD kernel seems to be focused also on operations, but this will probably lead to a humbling experience and walking back to using either OpenCascade or licensing a commercial kernel like Parasolid.

My goal is to have a simple prototype out before the end of the year, but work might get in the way :)

(here's some experiments I did with Metal and Vulkan: https://github.com/arjonagelhout/graphics-experiment, the IFC parser is currently not open source yet)

I've been just screwing around and building little apps, mostly seeing how quickly I can get something going using ChatGPT or Claude. Seems like Claude in particular is great with code. The most recent thing I did was a little app [0] to help one of my parents log their blood pressure readings easily, since they had to do it a few times a day in different positions and such. I've used that as an excuse to learn how to make something really basic, single task, easy to use for folks that aren't so great with technology. I'm also trying to learn a bit more about accessibility in web development, which this is helping me do.

I have been so overwhelmed that all my side efforts have been tiny things for a year - actually since last Christmas when I had a few days off in a row and my wife wasn't demanding other work.

JSON Serialisation of GNU Makefiles:

I got quite far then and now, one year later, I'm hoping I will have the time to finish off the difficult bits: it's a way to get GNU Make to print out its internal database of targets and rules as JSON.

https://github.com/tnmurphy/gmake-experimental (feature/jprint branch)

It's a companion to the print-database option:

    ./make --print-data-base-json
You get output with all the targets, all the options on those targets. Basically everything that make knows. I have most of it working but not directory targets for example. Why do this? Well there are many uses:

1. tools to rewrite makefiles - to simplify them or find duplication and implement transforms that remove it. e.g. all your CC commmands have nearly the same parameters - so make a variable or a macro containing the common ones and simplify all your commands (basic things like that could still be very handy).

2. tools that translate makefiles into other build formats. This is a big one for me. Make is like an almanac of all the build features one can have (nearly) but all done in various ways that make them of limited use. There are existing tools that are better in some areas and always the holy grail of the one build system that does it all and does it right. One is never going to get there however if one cannot convert existing work with a fair degree of ease and in a way that can be shown to truly do what is expected.

Sorry if I think the existing examples are not very good and that upsets you - they're all tailored for specific situations and work really well in those situations and if that's all you need then they tend to seem amazing. ...but...when you try to do something that's not in the examples they can be very inflexible. tup's basic idea (inverted dependency tree) is what I want because it lets you have giant makefiles that load quickly. The ability to describe a logical structure like Meson does is important too. Cross platform tests and option setting like CMake...check. Then some features from SBS (Symbian build system which none of you will know) and all the really interesting features of GMake that suck in implementation/performance such as pattern rules.

So this Christmas I hope to update to the latest version of gmake and handle directories.

I've been working on some projects in Rust relating to image processing and rendering. I'm between a few projects at the moment though but the biggest one is an image processing application I've been working on for quite some time. A lot of stuff I've programmed and learned about over the last 3 years has been leading up to the goal of making something like this haha. I wanted to leverage OpenCL for compute but I had a lot of trouble getting OpenGL OpenCL interoperability to work.

A big motivation for such a project is my passion for photography. I've taken many thousands of photos over just the last 2 years alone. A lot of them are digital, and so far a few dozen rolls of film. A big challenge for me is that I'm not satisfied with the tools available to develop the raw files that are free or open source. Either they're quite finnicky, or they have noticeable issues with color transformations.

I've done a lot of rendering projects over the last few years relating to color that have been focused on getting a better understanding of working with color spaces. Lots of 2D and 3D fractals haha.

Unfortunately I've had quite a turbulent life the last few years so development is very off/on. Every autumn for me seems to be a period of change, this one no different as I'm moving and I'm a bit uncertain of things. However, a side project to all of this has been an OpenGL project where I'm working on things related to voxels! I did a lot of research on data structures like interval trees, octrees, segment trees, etc. It does seem that a lot of people jump for the octree approach, however I've been able to render a lot of voxels with just a hashmap of chunks and a 3d array haha (albeit, mostly initial implementation of chunk generation, single threaded at that!). With this I'm hoping to explore OpenGL compute as I intend of generating world geometry in compute shaders :D

I havent published a project in a while and I'm hoping to get back to putting things out there, so hopefully some of the stuff I've been working on goes well and I can put it up on GitHub or something

    Thank you for working on light theme, it seems that 90% of themes are dark nowadays. Depending on languages I switch between dark and light themes and for the latter there's lot less choice.

      It had been a community request from the beginning. Personally I still use the default Monokai Pro, but dark themes aren't suited for coding in very bright environments, like outside for example. Then a light theme really works better, and I'm glad I can offer that now.

I created a Weird Clock that shows the local sunrise and sunset within a conventional 12-hour clock face. This normally would only work on a 24-hour clock face, which is kind of unfamiliar to most people, so I developed a way to show a 24-hour day within a 12-hour clock face; essentially it shows a 2-turn spiral so both night and day will fit. This needs to know your location in order to compute your local sunrise and sunset, so don't freak out when the browser asks for location permission! Includes option to enter lat/long and other goodies. Works on phones but better on a large screen. https:\\www.coolweird.net

With the Wordpress fiasco only getting worse, I have been working hard on launching my MIT-licensed open source CMS. I bring to the table with me running high traffic news publications on my own custom CMS'es and my learnings from it. What scales and what doesn't. Hopefully the community will like it and embrace it. On the surface, it sounds like a simple project, but CMS'es are quite complex than they appear (hence the time taken).

There are a lot of things the CMS universe accepts as normal, which shouldn't be the case. Even without the drama, Wordpress simply sucks as a scalable solution for large traffic sites without blowing up the hosting costs. Given the ongoing fiasco, I even think if Wordpress has been deliberately built this way as a funnel to upsell the hosted commercial offering to large scale news publications.

Hopefully, this benefits everyone affected by the Wordpress fiasco, as that is my primary goal. This has been a decade long project close to my heart and it is finally coming to an end.

I am also documenting this journey on Medium if anyone's interested.

Updating some of my negative core beliefs. Years of Buddhist meditation only got me so far. But two months of this new technique, and I finally see a path to being able to program my emotional self like I program a computer. Here's how it works.

Step one. Identify the negative belief you want to change. This is the core belief. It is something you feel is true. For example, “I am a bad manager.”

Step two. Create a statement related to the belief that you believe is not true. This is the false statement. For example, “No employees Ive managed have thought I did anything right as a manager.”

Step three. This is the training step. You spend a few minutes following your breathe to quiet your mind. Then you think the false statement and watch the emotional reaction the mind has to it. The reaction is an aversion, a kind of disgust. Then, say the false statement and the core belief together. “No employees I’ve managed have thought I did anything right as a manager. I’m a bad manager.” Repay the false statement and core belief together again and again, watching how the mind rejects the false statement and that aversion feeling lingers as the core belief is thought.

Step four. Repeat the training step in daily sessions. During the session, repeated think the false belief and core belief. The session should last at least ten minutes. The daily sessions should be repeated for at least a week, and longer for more deeply held core beliefs. Over time, you come to reject the core belief just like you reject the false statement.

Here's why I think it works. There is a rational part of the mind in the prefrontal cortex. It is what we think with. But it is not where our beliefs are. We can rationalize our way to a new belief or to change a belief. Instead, beliefs are felt. And they’re felt in the limbic emotional part of the brain. The limbic system is mute and cannot think with words. The prefrontal cortex can’t directly talk to the limbic system with words. Instead, the prefrontal cortex must communicate with emotion. You have to train the limbic system to feel differently about a belief. You can’t use positive affirmations because they are not felt as strongly as aversion.

    Does that mean you actually know that you're a good manager but can't shake off the feeling that you're not? And this technique is a way to achieve that?

I've been working on the idea of building synthetic workers. I'm trying to implement a planning workflow system for scenarios where the workflow definition, the environment, or the task are not well defined. I also ended up implementing a micro Palentir plugin system to support the action system for the synthetic users.

Its a cool project that gave me immense pleasure to built, however its unfortunately a intellectually masturbatory one, because although the tech is cool, I haven't found a cool application for it. If anyone is interested hit me up.

I'm building an AI Data Engineer @ Ardent AI. It's an autonomous AI Agent that can perform data transformations in your databases (mongodb,postgres,supabase for now) from plain english queries

It drops directly into your stack, no new configuration needed

It has its own compute engine and will soon support spark to be able to dynamically perform large scale ETLs and data manipulation.

I also am working towards supporting automatic data pipeline building and data quality checks.

It's live right now @ https://Ardentai.io

i like to bounce between projects week to week and am in a huge phase of just trying to build services i pay money for.

the first fun thing i'm working on a roguelite(?) type of petsim in dragonruby for my wife and i to play.

then i'll go back to working on my mtg collection / deck builder app. instead of rewriting in nextjs i decided to just go modern rails with it and i am honestly having a lot of fun. a redesign helps too, but once you get the hang of turbo/hotwire and stuff it really isn't that bad.

another thing i've got kicking is writing up a portfolio site for my old photography since that current hosted plan is about to renew. this is more of a stability and performance issue as i really liked using Format, but every single time i go to show my port to someone irl i would either not load or take forever or have images missing. extremely frustrating.

i'm very tired of SaaS pricing going up (with unwanted features) and user experience and value going down. reallllllly fighting the urge to just build a clone and try to take a cut of the overall business.

Pondering doing a hardware startup to offer a battery buffered electric kettle.

110 volt plug, 220 volt power.

(You could use the same concept for lots of other appliances too)

  • binoct 14 hours ago

    I love the idea and thought I'd do a rough check on the math:

    Assuming the goal is to match the power delivery of a high power UK kettle, looks like the batteries will need to step in and produce about 1kW of power for the duration of the boil, something like 50% on top of the standard 15A US circuit. I know on paper the circuit ratings are nearly 2x, but in practice it sounds like it's closer to 1.5x for the average kettle comparison.

    80% efficiency for the heating coil, 1.6L of water, you need about ~750kJ (200Wh) get to a boil from 10C tap water.

    So you'll need at least 70Wh output from your battery, and it needs to provide 1kW continuously. Accounting for conversion losses and some buffer to avoid deep discharge I'll target 80Wh. At 1kW that's a continuous 13C discharge rate, which is pretty high. Hobby-oriented LiPo packs will do it, but I'm not sure how they would hold up for consumer product safety and longevity. LiFePO cells could be a good choice since density is _less_ of a concern, and are readily available with 20+C continuous discharge.

    I don't know my power electronics very well, so I'm not sure the best way to merge the outputs. Any conversions are going to eat into total power and thus boil time, just rectifying the AC will take 20%. Maybe it makes the most sense to have two separate coils, one direct from AC and a second from the battery? With smaller cells in series, say 10+, to get a decent voltage it could end up with a manageable current to use directly with the 1kW boost. In that case the only expensive power electronics needed would be to charge the batteries.

    Also have to figure out how much recharge time matters to people, since by default it would be an hour or so.

    It's going to have a chunky, heavy base, and guessing it will have to be pretty expensive for what it does, but I like it.

    • shiroiushi 9 hours ago

      The whole idea sounds pretty insane really. Who's going to pay hundreds of dollars for a battery-powered kettle just so they can save 1-2 minutes of time (and less if you're just making enough boiling water for 1 cup). I use a little 100V (900W I think, according to the label) kettle to make tea, either 1 or 2 cups at a time, and while it's certainly not as speedy as those EU/UK market kettles, and a bit slower than a US kettle, it's fast enough.

      A battery-powered one might save me 1 minute of time at best, but will cost probably at least 5-10x as much for the kettle, it'll be MUCH larger than my current kettle (that battery pack and power electronics needs space) which is a problem with my tiny kitchen, and I have to worry about how long the battery will last and how to dispose of it later and if I can even replace it.

      This is really a solution in search of a problem.

      • binoct 8 hours ago

        There are lots of products that aren’t _necessary_ at all but bring an amount of fun to the world. This feels to me like one of those. Not convinced it could even recoup development cost, but I’d be happy to be surprised. There’s certainly a niche for well off Brits (and EU folks) living in 120V land hankering for a fast cuppa.

        • shiroiushi 7 hours ago

          The reality of product development and manufacturing is that economies of scale affect prices such that low sales quantities (i.e. a "niche product") generally means extremely high prices. Also, the BOM cost alone is probably going to be high, because of the huge batteries needed (with high current ability) and the power electronics involved. Then when you consider the safety ratings and certifications needed (since this is something that could easily start a fire with the power levels involved), I don't see how it could be sold at any kind of reasonable price unless there's a really big underserved market.

          Sure, if this device could be sold for USD$50, it might sell some to people like you say, but how many of these people would spend $500 or more on it?

    • bilsbie 2 hours ago

      Thanks! Good calcs. As far as merging I was thinking simply two separate heating coils. One AC on lower voltage dc.

An entity database (rest api on postgres so dB is a stretch) with a crud frontend for platform engineering. Adding a similar control loop to kubernetes and bash script (or executables) as the extension language.

This way you can write all of your glue code into one platform and create an IDP at the same time.

This came from a lot of situations where I'd need like one random thing to be stored in a database, but adding that complexity is a bit of a hump for just one thing.

Also crossplane is a really cool idea but starting a kubernetes cluster so that you can manage infra sounds insane to me, even as an avid kubernetes fanboy.

You might think of it a lo-code tool, but I'm aiming more for it to be a no-code tool, as in the level of sophistication should be such that there is rarely a need to touch the generated application.

For the last little while now, I've been spending a lot of my spare time learning to work with a language called AgentSpeak[1] using a platform called Jason[2].

Briefly, Jason is a platform for building intelligent agents based on the BDI (Belief-Desire-Intention) software model[3], which is in turn based on the Belief-Desire-Intention cognitive model[4]. Broadly speaking, it's an event based programming model, where "events" are things like "gaining a new belief", "dropping a belief", "selecting a plan to execute" (aka an "intention"), etc. AgentSpeak programs (normally) run "forever" cycling through a "reasoning cycle" that involves perceiving the world, updating beliefs, choosing intentions, executing intentions, communicating with other agents, etc.

And to commit a little self-plagiarism, from a recent post on LinkedIn:

----

On the one hand, AgentSpeak is basically a logic programming language with a lot of #prolog in its heritage. On the other hand, the runtime is all Java and to do anything interesting you have to write your custom Environment class and other helper functions in #Java. And while the interop is seamless in a way, getting your head around the execution model and knowing what's really happening at runtime can be a bit tricky.

Still, it's starting to make sense. And I do think this #BDI inspired approach has a lot going for it. I'm just looking forward to getting to the point where I can really start to exercise this. I have a few things that I want to accomplish soon:

1. I want to create a BDI agent that I can connect to an #XMPP server so I can talk with it from anywhere.

2. I want to start working on customized perception, using neural networks and various sensors (web-cam, microphone, accelerometer, distance sensor, etc.) to create an embodied agent that can truly sense its environment.

3. I want to take a stab at integrating some symbolic reasoning. I've given thought to trying to adapt the "belief base" to be an #RDF triplestore (probably #Apache #Jena) and include a reasoning engine or two. This all starts to get really speculative from here, but I spent a lot of time working on abductive inference a couple of years ago, and I'd like this thing to be able to use abductive inference, along with deductive reasoning, rule induction, possibly case based reasoning, etc. all in one system.

4. Might experiment with implementing a #Blackboard architecture and have specialized "problem solving" agents that collaborate by using the Blackboard in some situations. What would be really interesting here would be to figure out how to seamlessly translate in and out of a structured representation that lets you use existing specialized code for things like, eg. R for statistical operations.

5. And of course, experimenting with continual learning, as opposed to the "batch training job" stuff that we all use for ANN's today. This gets really speculative as well, but I want to explore contrastive learning, Hebbian learning, associative learning, operant conditioning (ala Pavlov), etc.

[5] above is why you'll see me spending as much time lately with Developmental Psychology, Infant Development, and Cognitive Psychology books, as with "AI" books per-se. I still believe that getting an AI that can learn from its environment, and build up useful mental representations with the minimal set of hard-coded behaviors, will be the best way to make progress with regards to #AGI.

----

I didn't mention it in the LinkedIn post, but as part of all of this, I've been building a hardware platform for some time now as well, where said platform is meant to support "perceiving the environment" so the system can learn from the physical world. It's not finished yet, but today it includes a GPS receiver so it can "know" it's location in physical space, a 6-DOF accelerometer/magnetometer/gyroscope board so it can sense movement (of itself), and two microphones (for stereo audio input). Future plans include one or two webcams to emulate vision, and possibly some other sensors: IR and/or ultrasonic distance sensors, temperature sensor, humidity and barometric pressure sensors, etc.

Also in the "speculative / for the future" category: AgentSpeak programs don't have any inherent notion of learning built into the model. All "plans" (aka "desires" or "candidate intentions") have to be coded by the developer up-front. This is obviously pretty limiting if you're trying to create truly autonomous agents, so another area I want to dig into is how we might combine work on "AI Planning"[5] to dynamically create new plans.

And since this has kind of turned into a big brain-dump of stuff that's on my mind, I'll finish by saying that I've been chewing on some ideas about explicitly modeling other "mental states" that aren't part of the base BDI model. Things like "attitudes", "values", different emotional states (eg "boredom", "frustration", etc.), "curiosity", "confusion" / "cognitive dissonance", and so on.

Jira Align sucks as a planning tool. But my company insists on using it for product planning. I got fed up with it recently and decided to create my own planning tools using python and REST API (which sucks too btw). My short term goal is to automate all the syncs I have to do from my personal notes to jira align, eventually who knows where this goes.

A point anc click model pretraining tool. Simply put all of your data into a directory of directories. Next, point the software to this directory and a few days later you get a pretrained model out.

Refining 3D printed parts for a hobby grade 3D metal printer. The complex internal geometry of the design still takes 4 hours of machine time to produce, but at least home users will be able to replace high-wear items themselves.

Boring RF stuff related to Metrology.

Adding some features to a fork of DerFetzer/spectro-cam-rs to validate some narrow band-pass laser filters.

Other boring stuff people really won't want to hear about. =3

I am building a kanji learning webapp (soon to be a PWA) using open dictionary data, indexeddb, and vue.

https://shodoku.app/

It is almost feature complete, but good enough for my private use, as I’m using it my self to study kanji. I have maybe a three or four more weekends until it is completely finished, with dark-mode, data backups, input by radicals, etc.

I built CryptoGain, an (currently) android app for cryptocurrency market tracking and analysis. Started it after getting frustrated with the limitations other apps put on technical analysis features behind premium tiers.

It offers:

- comprehensive technical analysis tools without artificial limits or cost

- customizable price alerts

- portfolio and watchlist management

- live market data across major exchanges

- available in 15+ languages

Currently serving a few thousand users and actively iterating based on feedback. The focus has been on making advanced trading tools accessible while maintaining a clean, intuitive interface.

Store link if anyone wants to check it out: https://play.google.com/store/apps/details?id=com.cryptogain...

Would love feedback from the HN community, especially around what technical analysis features you find essential but are often paywalled in other apps.

For a fun weekend project, I built Boardle - a daily wordle-like game where you guess popular boardgames using stats from Board Game Geek. The games are from BGG's top 150 games as voted by the community, so fair warning if you aren't already someone who plays a lot of modern boardgames this will be very hard as all the games are very nerdy

It’s called Midom Project AI. https://midombot.com/b1/home

I’ve written a project suite composed of familiar software with AI Agents integrated into this familiar software, who are both editable and duel experts in the software at hand and other expertise, any expertise, callable on demand. I realize this is abstract, so here’s some examples:

People collectively group to do things; they group into organizations like companies, departments, and teams. These organizations of people can be mirrored in my software as “organizations”, and each organization has control over their own custom and private AI Agents, they can clone, edit and use. An organization can be open to any members, or private and require membership requests. Once in, members can be kicked out for unruly behavior or leave on their on at any time. Additionally, an org can be visible or invisible, where a private invisible organization might be people who simply don’t want to be bothered, they’re at work.

Within an organization, private projects may be created. Organization Projects are collections of org members collaborating on a project. They use the organization’s customized AI Agents as these agents are integrated into the word processor, the spreadsheet, and multiple chatbots each with some integrated purpose within the suite of project software. People don’t always want to work in groups, and solo people often want to privately and invisibly join groups to do their own private things. We fully accommodate that. Users can be “invisible” to other users, only revealing themselves to organization owners for membership requests, and then disappearing again. Once joining a collaborative project, they become visible only to their project collaborators.

Yeah, that’s still abstract, it is the foundation which enables users to get productive and creative. The system has a few example organizations to give users AI Agents they can immediately use, and ideas for creating their own organizations with their own customized AI Agents:

The Creative Writers Workshop is a collection of writing genre specific professional writer chatbots that are trained to act as literary critiques and muses for those authoring their own technical documents, science fiction, romance, autobiography, young adult fiction, mystery or horror. Conversations with these chatbots are augmented by “SuggestionBot”, who is making sure stones are not left unturned, and “LaterBot”, who is maintaining what needs following up. Independent Paralegals is a collection of personal paralegals that help people seeking or with legal issues collect and formally document their issue for formal use. These paralegals include a demographic spread, because these issues are often sensitive and are complemented by demographic sensitivities: divorce, property disputes, adoption, and personal injury. The Play Zone is a collection of entertaining and fun AI Agents, such as dungeon masters from alternative dimensions, here on vacation playing D&D. There are also interesting personalities for fun conversation, such as an immortal, a Polynesian Sun Goddess, and Mark Twain.

The Mental Health Tune Up Clinic is pair stress management chatbots that help people manage their self conversation bias, otherwise known as “playing yourself”, promote critical analysis, and guide users potentially toward greater life satisfaction. Immigration Law Support is an organization intended to demonstrate a new client acquisition method for immigration law firms that pairs a legal intern or law student with an AI immigration attorney, and together they handle new client interviews. An otherwise costly task at law firms, because it requires an attorney’s time, time they cannot charge against a client. Each of these organization types handle private and often sensitive information. To accommodate that everything that occurs with the AI Agents is private to the project their use occurs, data collected and shared between the AI Agents for request satisfaction are maintained encrypted, and all AI Agents are private to the organization they are owned. So, if one is stressed and wants to talk to those stress managing chatbots, make a project in their organization and invite nobody else into your project, you’re the only person that can see anything in that project.

Also, none of this has sharing or any social media type networking. This is for creative, private, professional, solo or collaborative work, whatever that work may be. Including support for geographically remote collaborations.

Did I mention voice? Yeah, one can use their voice in place of the keyboard for a lot here. But not the spreadsheet editing itself, just use your voice to ask the spreadsheetBot to make the full sheet you need, rather than muck about at the individual spreadsheet cell level.

At this point, I’m layering in additional privacy handling, which also requires “double blind” communications for those invisible users that communicate with invisible organizations, and a lot of documentation, with examples. It’s actually just a slight augmentation on familiar office type software: I’ve added on demand editable subject matter experts to co-author with you. But that’s kind of huge, actually. People need examples to understand what this opens up.

I’m excited to introduce Trendly, an app I think you’ll find really useful.

Here’s what we’re solving:

* Social media is full of fake news and lacks depth, yet many still rely on it for updates.

* There’s too much content online, making it hard to find what really interests you.

* Switching between platforms to get full details on a topic is tiring.

Trendly (https://trendly.global/) is a mobile app that curates a personalized feed with trending updates based on your interests. It lets you dive deeper by asking follow-up questions as a chat—all in one app. We’re in the early stages, so while the chat function isn’t live yet, the other features are ready:

* The feed acts as a recommendation engine, curating content based on past interactions.

* Delivers concise, bullet-point summaries instead of lengthy articles

* Pre-generated Q&A for easy understanding

Check it out and share your honest feedback!
