Hacker News with Generative AI: Real-time Systems

Julia: C codegen considered unnecessary: go directly to binary, do not pass C (arxiv.org)
Since time immemorial an old adage has always seemed to ring true: you cannot use a high-level productive programming language like Python or R for real-time control and embedded-systems programming, you must rewrite your program in C.

Back to basics: Why we chose long-polling over websockets (inferable.ai)
Like many teams building real-time systems with Node.js and TypeScript, we've been exploring ways to handle real-time updates at scale. Our system handles hundreds of worker nodes constantly polling our PostgreSQL-backed control plane for new jobs (tool calls issued by agents), while agents themselves continuously pull for execution and chat state updates. What started as an exploration into WebSockets led us to a surprisingly effective "old-school" solution: HTTP long polling with Postgres.

Real-time Linux leads kernel v6.12's list of new features (zdnet.com)
It took its own sweet time -- over 20 years! -- but real-time Linux finally made it into the mainline Linux kernel.  It's baked inside Linux kernel version 6.12. This is a major new release.
