Performance Hints

Excellent resource for keeping an eye on performance issues in your codebase. It's very C++ oriented but most of the insights can be generalised to other ecosystems.

History LLMs: training the largest possible historical LLMs

Interesting research. Can it give insights on the pervasive views of the time?

Things went too far with the cloud monoculture. It's time to remember that it doesn't always makes sense, and in the case of databases maybe it's rarely worth it to go for fully managed options.
