I am trying to build a simulation that lets a simulated organism come up with its own small language, purely learned from sensory input: https://github.com/JoergStrebel/VirtualZoo/blob/main/compute... I would like to implement the ideas put forward by Stevan Harnad in his symbol grounding problem paper (Harnad, 1990).

With AI IDEs, Personally I had to generate a tons of md files for planning a task, analysis on the code for something or other, a task doc for a feature - a summary to paste into the clickup ... and I saw many devs keeps on generating them, and all tucked away into folders. Good, okay.

For the company I'm currently working I had made a VSCode extension where I can sync the task doc with clickup via frontmatter.

I decided to take it to next level as a side project. I built a CI integrated, git-native, agent template transformable syncing pipeline with git MD files to any project management tools. That means, either you can save your md files vanilla in your wiki (thus using the clickup AI search to dig up later, get insights etc) or you can use a AI agent template transformer to turn it into a task template (Background, acceptance criteria, functional requirements etc.) and update or create a task on a board.

I've been working on it now. I don't know how it will fare, but I feel like product is coming up nice.

Great idea!

I was actually working on last weekend with something that has similarities. I am working on USM.tools, which allows specifying your services in structured way.

There is a need to specify some of the data in semi-structured way, and I am using markdown for that.

So there is this interesting relationship between unstructured, semi-structured and structured data, and markdown hits that middle ground.

Can I suggest you make some Jira etc. templates on your landing page clickable, so a visitor can grasp your idea more easily? For me it was not clear whether the specs are just plain markdown, or do you have some additional tagging there.

Great idea you got, what would be a classic use case? We have a data source and we can define the API structure to get them?

Sure! thanks! thats good idea, to have it clickable and true that needs needs to be easily understandable.

Service management is business oriented, what is the service we are providing and how do we deliver it, and how do we agree with the customer what we deliver. And when the data is structured, other interesting oppurtinities become possible.

This particular use case is people working together to collect data in a workshop. 10 people don’t want to see somebody searching for the right place in a form, it interrupts the flow of the meeting. You need to capture the ideas raw, and then structure later. That is where question anout how unstructured data is captured in strucured format pops up.

It is a workflow I directly support in my tool, not a generic tool like yours.

I'm continuing work on my daily procedural logic puzzle, Ruly.

https://playruly.com.

You play by setting rules onto a small grid of numbers to maximise your score.

My focus the past few weeks has been on refining the difficulty by experimenting with different rule types, and improving the UI.

I'm pretty happy with the look and feel now but feedback is always welcome, and I'm especially keen to hear what you think of the level of difficulty of the puzzles. It's a tricky balance to introduce variety without adding complexity.

There's a (very) small contingent of daily players now which is really motivating.

Your comments very welcome.

CaseDaemon: automated intake handling for immigration lawyers. Given a USCIS form to fill out and a set of documents and information, CaseDaemon automatically fills out the form with what it has and prompts the client (directly or via the user) for additional documentation or information needed to finish the application. Takes out a bunch of the back-and-forth between lawyer and client, and the busy-work of the lawyer mapping data to form and tracking requirements.

The product will be ready to use in a few weeks, but take a look at our homepage in the meanwhile, curious what people think!

I made sdf2stl.saej.in

You can use it design 3D objects with mathematics and bring them into the real world with 3D printing.

You can use it to create 3D models that are impossible to create with CAD, CSG, sculpting, or mesh-based tools.

You can build on a decade of community SDF development on Shadertoy because sdf2stl uses the same language.

A few days ago I may have become the first person to 3D print the equation x^4+y^4+z^4-x^2-y^-z^2+.4=0 (Goursat's surface) https://www.printables.com/model/1713835-goursats-surface

Please try it out and tell me what you think.

I wanted a faster, easier mapping app to plan motorcycle rides for myself and with groups, so I finally bit the bullet and started building my own at the beginning of this year.

I got to the MVP state which was useful for my personal use case in about a month. I took it further than that as a learning exercise and as a means to share it with others. Some features that came later are live cursors (like Figma), elevation chart and grade overlay, and QR-code enabled collaboration links to make in-person sharing simple.

Check it out! https://plotalong.app

Figuring out the exact UI/UX I wanted was the hardest part. I did the branding myself, handdrawn on paper, traced in Procreate, and vectored in Sketch. Fast iterations and a good test suite made it possible to try lots of different approaches and refine the one I liked the most. There are roughly 4000 unit tests and over 300 e2e tests that run on multiple environments with fully automated CI/CD.

I’m using Mapbox for the frontend and the whole app is basically just a monolithic Cloudflare Worker. Claude pretty much implemented the entire thing. I got a lot of mileage out of self hosting a Gitea project and recording all my planning sessions as Milestones and Issues. Claude has his own account without admin privileges. The process of managing a team of agents to build this practically autonomously was a bit jaw dropping and eye opening to be honest.

I would love to hear from other pleasure & sport drivers about the features they use or want the most in a routing app. I have an Android app in Play Store review, if you’d like to be an early access tester shoot me an email at my handle @plotalong.app

Very nice! Does the sharing feature allow live location sharing? That seems like it would help a lot, especially when group members are in separate vehicles.
motoroco 18 hours ago||
No, and while that does sound like a pretty obvious feature I should clarify the app is about planning, not turn-by-turn directions. You can open Plot Along routes in Google Maps, Apple Maps, multiple GPS formats and more

The idea is everyone opens the same route for coordinating and there’s just one source of truth for the group. And then when you’re all about to hit the road, everyone can use the nav app they’re already familiar with (or that’s built into their vehicle)

I will tackle the navigation aspect at some point if I do keep up on feature dev, though!

I understand the need for this and like what youre doing. Ive tried to look before for a good app for this ans always been disappointed. I like the way you've deferred the map direction call so moving a pin around doesnt feel sluggish like other apps Ive used.

Suggestion if youre open to it: emoji or text badges for each stop (e.g., or )

I also think itd be helpful to have route leg times shown directly on the map as popout tooltips. Knowing stop 2 to 3 is five hours is critical, and how we plan.

Suggestion for your pay model: I think it would be lovely to be able to use this with no option to save. Or, maybe a single fee for an administrator that allows up to x users for one month with only one routr? I only do these kinds of trips yearly, so a monthly fee for three collaborators just wouldn't work. Would we all sign up then disable our accounts? Its hard to imagine that model working for me (RV road tripper with 3-4 people) I think Id be willing to pay the $5/pp that allowed me and x friends to all jump in. Having each person set up their own paid account feels like a harder sell.

Thanks for the feedback. As it is right now, only one person needs to subscribe in order to collaborate. I’ll definitely make that clearer in the marketing material!

I like your emoji suggestion. I realized little while ago I need to distinguish between different types of waypoints so this is great validation

I think you’re right about getting people into the actual app faster, before signup. I’ll have to prioritize that sooner than later

I had an idea about explaining ML predictions without direct access to the data or the model: provide basic stats about your data, use them to generate synthetic data, then train a surrogate to predict your model's predictions on the synthetic data.

Could be handy for model risk management and governance, e.g. if you need a challenger model for SR 11-7 without all the hassle of getting access to the original data, getting the black box model set up, and so on. I wrote it because I remember having to create "throwaway" models to show why I needed a better model; it would have been nice to just make a couple of API calls instead.

Still chugging away at my NES rhythm game. Currently, in addition to climbing the content mountain (so, SO much pixel art and music needs to be made) I'm also slowly learning video editing workflows. I was able to put together a brief gameplay trailer this last week:

https://store.steampowered.com/app/4129270/Tactus/

Right this second I'm looking for an alternative to After Effects that runs on Linux systems, as kdenlive has some limitations with its layering implementation. I'll probably give Blender and Godot both a whirl, as I want to get more comfortable with those tools for future projects.

I can't overstate just how much I love seeing a NES game developed in 2026. It looks great. I really like the music too.

Have you considered also releasing it to itch.io? (I don't do business with Steam due to DRM and their inaccessible website.)

I would happily purchase a NES ROM file so I could play it on my pitendo (RPi3 in a case that looks like an NES).

I'm not well versed in video editing. That said, the people I know who are tend to use Da Vinci Resolve.

zeta0134 19 hours ago||
It is indeed also on Itch. I'm planning to release both, along with a physical cartridge at some point. It's a real NES game, so a ROM is included. (No DRM, of course. I'm not even sure how you would achieve DRM on a ROM chip.) I test on an Everdrive N8 Pro. It's a big game, so simpler flashcarts tend to not be able to run it.

Nice job. I'm assuming this was inspired by Crypt of the Necrodancer? It even has a similar looking "bounce" motion when the main player moves.

zeta0134 19 hours ago||
Aye, the inspiration is not subtle. Technically it is the latest entry in the "rhythm-based roguelike" genre... which to my knowledge mostly includes CotN and its sequel, Cadence of Hyrule. Both are excellent, and I recommend them highly. Of course I'm unaffiliated, so this is more of a spiritual successor (... demake?) and is its own thing in terms of IP.

I built on online multiplayer boggle game back in 2008 that somehow drew a lot of users, many of whom still play every day after 17 years. About a year ago I started a rewrite from scratch in more modern technologies but stalled out after getting to about 80% of the way there. A few months ago Claude enabled me to finish the remaining 20% and was able to relaunch mostly successfully! It's been tough though. I'm a dad with three kids and use Claude all day at my day job and my interest in working late isnt always there. But I'm eeking my way to something that hopefully can stay up for another 17 years.
