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

I had a similar idea, as alternatives were.. eh.

I also had an idea to get a ~12MP camera and set it up on an active game of MTG, just because standing up and having to read other people's deck was bothersome. My eyes are bad, and I end up not reading other people's cards because I feel weird hovering over them when reading.

I would then cast whatever is at the person's deck onto an app so I can manually read the cards. Since my phone is of a similar ratio as a playing card, I figured this might be a nice way to play.

I'm working on a full blown terminal emulator called "terminal-use", or "tu" in short, for coding agents. It allows agents to operate fully fledged TUI applications including multiple windows, mouse control, etc. It can even self drive a NetHack session via Claude, if you want lol.

It's basically tmux for your coding agent, great for developing and debugging TUI applications as well, because now your agent has a closed feedback loop of applying changes and trying them out itself via tu.

I'm working on Coderbase (https://coderba.se/), a platform for running technical interviews. It started with live interviews cuz that's what I know best, having run over 3,000 interviews in my career, but I made it easy af to run this yourself too. I initially pictured it as a tech-heavy product (and it is), but my second client is a large recruitment agency that's using it both for internal interviews (for recruiters) and external ones (for candidates they're presenting to clients).

I didn't set out to do this. After I got laid off in December, a client quickly fell in my lap: a small startup in the middle of a massive investment round that needed to hire 25 people immediately, with only a CTO available for interviews. I created their content and ran their interviews while building the software at the same time. It started as Google Meet + CoderPad + Calendly and gradually became an in-house system. Unlike Proton (lol), I'm not pretending I built my own video call solution from scratch, it's just an off-the-shelf 100ms integration.

The content is all versioned and structured, which makes it fast to iterate on and easy to reason about. We use major.minor versions and only bump the major for backwards-incompatible changes, or changes big enough that comparing interviews stops making sense. Otherwise, any combination of question versions inside an interview format is considered comparable if the major versions are identical.

The interview itself is highly structured: once you define a format from the content library and the various knobs you can adjust, you can schedule interviews and run them using our integrated "room" (video call + multiplayer code editor, both recorded, with transcripts and playback) and "rubric" (the tool the interviewer uses for content, scoring, and notes during the interview). Once you submit/publish the interview, a report is generated immediately. Example: https://coderba.se/sample

Two interesting AI bits:

- "AI linting": a way to benchmark interview questions by running a candidate model and an interviewer model against each other. The candidate closely follows a defined skills profile, then we compare actual vs expected performance. More here: https://coderba.se/blog/product-update-unit-testing-the-inte...

- "AI draft": once an interview ends, it takes ~30s for the video and transcript to become available. Then we use basically every relevant artifact from the interview, with a PII redaction pass first: questions, scoring, incomplete rubric, transcript, code editor history. We send that through our LLM gateway, currently mostly using DeepSeek because the quality/value is insane, though I may switch to Mistral to stay on the better side of privacy. It sends back recommended scoring + writeup, which we present as Cursor-like suggestions you can accept/reject/edit.

Fantastic, the scrabble lover in me will enjoy this.
