good catch, it's naturally `ANTHROPIC_API_KEY`, but I could have been more specific.

Nice, I really like the recent Vulkan support.

my background is mostly Java so I know this happens-before: (https://docs.oracle.com/javase/specs/jls/se8/html/jls-17.htm...).

from the article: > [Note 8: Informally, if A strongly happens before B, then A appears to be evaluated before B in all contexts. — end note]

this is the Java happens-before, right? What's the non-strong happens-berfore in C++ then?

I recently was trying to build an AI assistant to help with various chess things, which took shape of an MCP server: https://github.com/shelajev/mcp-stockfish

it builds as a docker image which has stockfish and maia (maiachess.com) together with different weights so it can simulate lower-level players.

It was a fun exercise, I tried a bunch of local models with this MCP server, which isn't particularly optimized, but also doesn't seem that bad. And the results were quite disappointing, they often would invent chess related reasoning and mess up answering questions, even if you'd expect them to rely on the tools and have true evaluation available.

It was also fun to say things: fetch a random game by username 'X' from lichess, analyze it and find positions which are good puzzles for a player rated N.

and see it figure out the algorithm of tool calls: - fetch the game - feed the moves to stockfish - find moves where evaluation changed sharply - feed it to maia at strength around N and to stockfish - if these disagree, it's probably a good puzzle.

I don't think I got to have a working setup like that even with managed cloud models. Various small issues, like timeouts on the MCP calls, general unreliability, etc. Then lost interest and abandoned the idea.

I should try again after seeing this thread

This is a Voxtral WebGPU demo for audio transcription where everything runs entirely in your browser with Transformers.js and ONNX.

Saying CI is a developer experience thing is completely misunderstanding the point.

AI workflows, vibe coding and such only emphasize the need for proper test suites and for a measured release process, where you don't actually delete your production databases on the whim.
