Building throwdown.top: a free web app for making leaderboards for club crossfit competitions. The main goal was to build a tool for a friend who owns a crossfit box. The app is kinda simple (a few forms and tables) and not overloaded with features, but I was trying my best to make the UX comfortable, because I was the first user, and my friend - the second one :) It is battle-tested at real club events, so the early kinks have already been worked out, but feedback is always welcome! https://throwdown.top

I been diving into Neurosymbolic for the past 8 months, been working on a database that combines the best probalistic and deterministic reasoning into a single source of truth for AI agents and larger systems. http://www.oxid-db.com

Working out some details before dropping it opensource.

Nucleus programming language: https://github.com/zakwilson/nucleus/

It's still pretty early, possibly buggy, and almost certain to get breaking changes without warning.

My original thought was to combine Lisp syntax and structural macros with C semantics and see how much extra abstraction that would provide, but variants of that idea have been tried before. They may have been compelling at a certain point in time, but I think a new systems programming language in 2026 should offer more, so it does.

Some features include: strong typing, protocols (similar to Clojure or Rust traits), non-nullable references, error values, bound error handlers (a bit like Common Lisp), optional lexical lifetimes, namespaces, and no mandatory runtime overhead relative to C.

It's self-hosted, which I've noticed several new systems programming languages announced recently are not.

I had claude faithfully rewrite SimTower so I could play it in the browser: https://kvetch.io/conciliatower I wanted to re-play SimTower but found it too difficult to get running through emulation. Instead, I worked for 6 months with Claude Code on a complete rewrite, replicating all the functionality from a Ghidra decompilation of the binary, an AI-generated summary of the original source code and my memory of the g…

While looking for the game files I found this web player : https://www.abandonware-france.org/online/play/simtower/

I am working on a cyberpunk multiplayer, shared, persistent world which runs completely in a terminal, and you can access just by typing "vibeworld" in the terminal(https://github.com/SorBalda/vibeworld).

The idea is that developers and scientists can meet each other in the terminal in a funny way at 3 am while working.

There is a place in the moon where you can "scream" against your last LLM session and everybody can see your scream from the space.

You can create your avatar, share your github if u want too.

It is full of continents (the "physics" continent, the "computer science" one, etc.) and in each continent there are cyberpunk cities. You can create corners and expand the city, and enter. A 3D supercyberpunk animation brings you in the corner and you can chat with people who enters in the corner (corner=chatrooms). Also voice chat works if u active it. In your terminal.

In the moon there is a place where you can see the stars and everything happening on the virtual pixelated sky, water a plant (if nobody put water it dies), with a soft low quality chill music. If someone is in a room with you, you can see him and you can chat, even vocal chat exists.

It is perfect to let it open in the second monitor while working so that you can watch the stars while dying of tasks to do, and sometimes have some conversation with someone who is in your same situation.

It works in Linux,MacOs and windows:) _____

I am working on a Django-based JS-free forum[1] that I can self-host. Still need to work on some essential things, but the basic forum functionality is already there. [1]: https://codeberg.org/ZelphirKaltstahl/xiaolong-forum

Haha, along the same lines [1] [2] but trying to target and stay inside Cloudflare's free plan (workers, D1, R2 etc.) for hosting small simple forums of a couple hundred users. Along with AI-powered moderation. JS-ful in some parts - but mostly Rust cloudflare workers WASM. It can self-host as well in a single binary + sqlite. MIT. Trying to figure out a good defense to the bot-infestation problem next. [1]: Test sit…

I am planning to host my forum invite-only, so no randoms or bots will be able to post stuff. Additionally, if it picks up activity, I hope some of my friends would also help with moderation.

https://humansmap.com/?lb_tab=orgs 7M+ people and 3M+ organizations mapped, you can visualize entities associated with an organizations up to 1k nodes, or visualize someones graph visualization(relatives, partners, phd advisors, org connected to entity. Wikidata based. There is also a feed section: https://humansmap.com/?feed=1 Better for mobile use, here you can explore family dynasties, org memberships, interesting…

I think the concept is cool, but I tried clicking on stuff I'm familiar with, and I don't get the circles thing. For example, the French communist party (PCF) has Jacques Chirac in its first circle. He has briefly been in this party, but he mostly remembered as right-wing. Also the Fiorentina football club, should have its hall of fame striker Gabriel Batistuta in its first circle -he has a statue- while he appears i…

It uses Wikidata statements count, it is a metric of general notability.

It is not possible to have for 300k+ orgs the entities circles ordered by importance for the specific organization.

The feature is you can double click on Jacques Chirac and observe its connections to orgs like "the republicans", " rally for republic" and so on. The fun is in exploring graphs. You can also click investigate for a brief bio synthesis,

I started a 501c3 nonprofit last year to showcase / highlight relatively unknown but talented artists in other countries in Atlanta, Georgia and we finally completed a visa application to bring one of them to the US.

As an engineer it's been difficult but really fun learning to help promote visual arts, but AI helped speed up a ton of stuff I wouldn't have really know about (like setting up a kanboard to work alongside artists).

Extreme vibe coding!!!

* better squares-in-circle packing for n = 31 and n = 34: https://github.com/dllu/packing and https://erich-friedman.github.io/packing/squincir/

* vibe coded CAD application (paused due to lack of quota on my $200/mo plan). Rather doubtful if GPT-6 Astra can one shot a correct B-rep kernel but whatever: https://github.com/dllu/viboceros

* ray traced chess demo: https://github.com/dllu/chess-rtx
