When random is not actually random enough

https://ersc.io/og/blog/when-random-isnt-random-enough.png
The author suggests a more general API for random choices, allowing users to specify the probability distribution directly, rather than relying on low-level functions like random_u64(). This approach can help avoid common pitfalls and make code easier to reason about.

LLMs may have helped my RSI

The writer has noticed a significant reduction in repetitive strain injury (RSI) pain after adopting new coding habits, including using voice dictation and focusing on home row typing. This change may be due to reduced keyboard use and increased time spent writing English prose, which is more comfortable for their smaller hands.

The Query Transformation Pipeline

The OpenSSH team has received many security bug reports, including some from AI models or made with AI assistance.

Benchmark in Milliseconds

A micro benchmark should run for about 300ms to provide a human-perceptible range, allowing for easy comparison and iteration. This duration strikes a balance between precision and speed, making it suitable for intuition-based decision-making rather than precise measurement.
