Show HN: I built a sub-500ms latency voice agent from scratch

https://www.ntik.me/voice-agent-essay/agent-logs.png
The author built a custom voice agent from scratch, achieving a 2x latency improvement over off-the-shelf providers like Vapi, by optimizing model choice, pipelining the agent turn, and carefully managing geography and service placement. The key takeaway is that voice is an orchestration problem, requiring careful coordination of multiple models and services in real-time, and that building a ...

I built an RGB controller with Arduino

https://svana.name/wp-content/uploads/2026/02/20260228_151203-1-768x1024.jpg
Before Christmas, I bought a new computer case. It came with three built-in RGB fans. Unfortunately, the fans use a 3-pin aRGB connection, while my now quite old motherboard has a 4-pin RGB header. I am sure that I could find an adapter that would solve this issue right away. But there is no fun in that. Having experimented with Arduino for some time, now was the time to use my skills to ...

Against Query Based Compilers

https://matklad.github.io/assets/2026-02-25-against-query-based-compilers/1.svg
Query-based compilers use incremental computations to optimize compilation by re-computing only affected parts of the code, but its effectiveness is limited by the dependency structure of the source language. Language designers can leverage language semantics to manually cut compilation tasks into coarse-grained chunks, making incremental compilation more efficient and effective.
