AI-assisted coding feels a lot like a mix of management and coaching junior engineers, except you are coaching the LLM instead of a person.

Rust database developer starter pack:
- Arc<Mutex>, RwLock, Ouroboros, ArcSwap
- "Is atomic::Ordering::Relaxed enough here?"
- Iterator borrowing from itself
- "Polonius is not really ready for widespread use"
- Tokio async disk IO is just blocking IO in a thread pool
- tokio-uring: "Dead or dying?"

JetBrains IDEs have gone downhill in recent years. IntelliJ went from working almost flawlessly for Rust and Go to often having issues to the point where the IDE becomes unusable. I'm not sure how they are going to survive with free alternatives getting pretty good.

Out of curiosity I attempted a "100% AI generated PR" with Claude Code. It was very tedious. You either have to do a lot of handholding, which makes the whole process net negative, or you have to lower the quality bar, which can be fine in some cases.

This piece of code in RocksDB caught my eye. The exact same snippet exists in Snappy and many other projects if you search GitHub for the magic constant. I was curious what "problematic" means exactly. After some digging TIL CRC(A + CRC(A)) is always the same constant, regardless of A.

What a shame, BBC Radio 1 Essential Mixes are no longer available outside the UK. I've been listening it since around 2010. The show had a huge impact on me. Discovered so much great music thanks to it and met great people as a result.

What is the 2025 equivalent of raw, intense and politicly charged "Jahba - The Part Time Revolutionary" that dropped 20 years ago? krissrecords.bandcamp.com/track/bush-i...

Building software compatible with popular system's APIs and formats is a blessing and a curse. You can easily bootstrap integration tests - run side by side correctness checks and reuse benchmarks. But it also means reimplementing decades of legacy code, carrying choices that no longer make sense.

Ok, I have to say this. Claude Cloud is the first tool in the AI space since the release of ChatGPT that is both impressive and somehow useful.

Going back to my old key-value store[1] to add a long-requested feature after a very long break reminded me that concurrency in Go can become a minefield the moment you stop "sharing memory by communicating."
