Configurancy, written by Electric, emphasized what we should do when writing code is cheap.
What I find interesting is the concept of oracle testing, where the oracle (Postgres in their example) is the spec that the codebase needs to satisfy. The moral of the story is that we need specs and conformance suites, not just simple unit test cases.
Something Big Is Happening
Something Big Is Happening, written by Matt Shumer, is fascinating and long, but a must read.
The era of manual coding is over, and perhaps soon, “vibe coding” will become “vibe research” in general, where not only programming, but also research, will be produced with almost 100% assistance by AI agents. This will allow us to try out new ideas, and to find out which works and which doesn’t, with unprecedented velocity.
I like one piece of advice from this article:
“Spend one hour a day experimenting with AI. Not passively reading about it. Using it.”
243-Line MicroGPT by Karpathy
In sharp contrast with his NanoChat project and its DeepWiki documentation, the 243 lines of pure, dependency-free Python, MicroGPT, reminds me of his online videos on building an autograd engine. Surely someone will post a detailed tutorial soon, explaining these 243 lines line-by-line.
On a side note, the DeepWiki MCP definitely sounds very interesting and may be better than Context7. I have added it to my codex MCP setup with the command:
codex mcp add deepwiki --url https://mcp.deepwiki.com/mcp
