https://pond.sh I have been working on a one week side-project that ended up taking over a year… Working on it periodically with friends to add new features and patch bugs, at the moment I'm trying to expand the file sharing capabilities. It's been a journey and I have learnt quite a lot. The aim of this is to be a simple platform to share content with others. Appreciate any feedback, this is my first time building a…

Are you looking for contributors to your project?

Thanks for the interest, but we are not looking for anyone at the moment.

I'm working on two graph optimization libraries for quantum computers. The first one was released a few months ago and the next version will make it much more powerful. The second one is currently being tested. Both of them work on actual quantum computers, which makes them exciting :)

In parallel, I'm trying to figure out how to train a LLM for SAST.

I'm currently building my own coding agent, VT Code. VT Code is a Rust-based terminal coding agent with semantic code intelligence via Tree-sitter (parsers for Rust, Python, JavaScript/TypeScript, Go, Java) and ast-grep (structural pattern matching and refactoring). It supports multiple LLM providers: OpenAI, Anthropic, xAI, DeepSeek, Gemini, OpenRouter, Z.AI, Moonshot AI, all with automatic failover, prompt caching,…

You’ve done an incredible amount of work — I’m definitely going to try out the Zed integration.

I’m curious though, how significant do you think it is for the agent to have semantic access through Tree-sitter?

Also what model have you had the most success with ?

A few months ago, I built a simple athlete profile page for my son (Track sprinting) to log his performance and progress over time.

He liked what I built for him and I got jealous, so I expanded it with my own profile (Trail running).

Then, I got curious… Could I build a full web platform for people to track their sporting life? I mean we have LinkedIn and CVs for our job career, why not celebrate all our sports/training efforts as well.

After a couple of months on the side, I'm pretty happy with Flexbase. If you're into sports, give it a try and let me know what's missing for you.

Note: it's mobile-only past the front page.

https://flexbase.co/ My profile: https://flexbase.co/athletes/96735493

You can list the sports you're doing or did in your entire life, you can add your PRs, training routines, gear, competition results, photos. You can also list your clubs, and invite/follow your training buddies.

Honestly, I'm not sure where (or if) to expand it... Turn it into a Club-centric tool, make it more into a social network for sporty people.

Lots of ideas, but I'd love to find someone to work on it with me. I find that building alone is less fun.

Thanks for your sporty feedback.

I'm working on a tool for creating custom color palettes for web designs that pass WCAG contrast requirements: https://www.inclusivecolors.com/ - You can precisely tweak every shade/tint so you can incorporate your own brand colors. No AI or auto generation! - It helps you build palettes that have simple to follow color contrast guarantees by design e.g. all grade 600 colors have 4.5:1 WCAG contrast (for body text) a…

wow! can you please include the example for Okabe-Ito (Masataka Okabe, Kei Ito): https://jfly.uni-koeln.de/color/#pallet

  COLOR='#000000' # Okabe-Ito: 1 black
  COLOR='#e69f00' # Okabe-Ito: 2 orange
  COLOR='#56b4e9' # Okabe-Ito: 3 skyblue
  COLOR='#009e73' # Okabe-Ito: 4 bluish-green
  COLOR='#f0e442' # Okabe-Ito: 5 yellow
  COLOR='#0072b2' # Okabe-Ito: 6 blue/darkerblue
  COLOR='#d55e00' # Okabe-Ito: 7 vermilion/red
  COLOR='#cc79a7' # Okabe-Ito: 8 reddish-purple

Here on Croatian islands maritime traffic disruptions and power outages happen often. Constantly checking websites or searching paper notifications stuck on random street lamp posts is a no-go and timely information is important. I'm working on a mini-project which monitors official resources on the web and sends email notifications on time. Currently covering around 15000 inhabitants. https://skoljarev.com/bodulica/

Awesome! What are you using to send emails?

I am working on the little book of algorithms: https://github.com/little-book-of/algorithms A project to implement 1000 algorithms. I have finished around 400 so far and I am now focusing on adding test cases, writing implementations in Python and C, and creating formal proofs in Lean. It has been a fun way to dive deeper into how algorithms work and to see the differences between practical coding and formal reasonin…

That's a cool project! I feel like the presentation of Lomuto's algorithm on p.110 would be improved by moving the i++ after the swap and making the corresponding adjustments to the accesses to i outside the loop. Also mentioning that it's Lomuto's algorithm. These comments are probably too broad in scope to be useful this late in the project, so consider them a note to myself. C as the language for presenting the al…

Sedgewick's Algorithms book is great for practical learning but too tied to Java and implementation details. It is a bit shallow on theory, though the community and resources for other languages help.

That said, I personally prefer Introduction to Algorithms (CLRS) for its formal rigor and clear proofs, and Grokking Algorithms for building intuition.

The broader goal of this project is to build a well tested, reference quality set of implementations in C, Python, and Go. That is the next milestone.

My biggest inspiration for this project, though, is The Art of Computer Programming (TAOCP), that level of depth and precision is the ultimate goal. I'm also planning to include formal proofs of all algorithms in Lean, though that could easily turn into a 10-year project.
