Ask HN: What are you working on? (June 2026)

A browser extension to export conversations from Teams. I initially needed a readily available tool, I was ready to pay a few bucks for it. Turns out there isn’t an alternative for me because existing ones require instance admin to enable this, Microsoft Graph API permission, or some other requirement which I could not fulfill. Then started vibe coding it. Once it started working, I thought “I’m sure that there are people out there who needs smth like this” and pushed to GitHub and extension stores of popular browsers. Now more than 15000 people use this. https://github.com/gediz/teams-web-chat-exporter

I’m working on a tensor computing language/compiler called i with a simple explicit scheduling model (loop splitting, loop ordering, input “staging”). These mechanisms alone are enough to express complex algorithms like FlashAttention, generating target code with techniques like loop fusion, minimized intermediate allocations, and “online” reductions.

Right now there is a runtime and compiler targeting C, written in dependency-free Rust, and a minimal Python frontend. The project is very much proof-of-concept stage so not yet fast. Working on a CUDA backend now.

The goal is to enable automatic discovery of FlashAttention-style optimizations which is not feasible with current compilers.

Very open to feedback/discussion from anybody interested in or knowledgeable about tensor compilers!

I continue to work on my city builder game Microlandia, launched here in HN ~6 months ago. I originally predicted a few dozen urbanism nerds would play it, but now almost 10,000 copies sold. I'm still a solo developer but now I collaborate with 2D, 3D and music artists. Which is good because the original art that I drew myself for the launch was horrible.

I'm currently working on modeling energy, climate and new policies like universal basic income

This reminds me of what "Hell Mod" did to Diablo I: Basically reinvented the game as it would have been if Blizzard hadn't been constrained by money or time, and knew what worked from their sequels.

Man looks amazing, the detail level of the simulation seems to be in another level compared to sity skylines and co. If you need any help or just chat about this, reach out to contact (At) khorchani (dot)fr

After 1.5 years of development and two exhausting pivots, I’m incredibly happy to finally have our v1 live!

While most of the HR tech is rushing to use black-box AI, I built the exact opposite. It's a transparent, math-driven fitness engine. It extracts objective data from CVs and calculates how well applicants match requirements, letting you see the reasoning behind why someone scored an X%.
