What does $0=$2 in awk do?
The trick to understanding awk in all its terse glory is to understand its defaults. Most solutions you see in the wild are a clever symphony of awk defaults stacked on top of each other.

How to build an absurdly backwards-compatible website

TLDR: Neon separates storage and compute, substituting the PostgreSQL persistency layer with a custom-made distributed storage written in Rust. Due to this separation, some nodes don’t have persistent disks. The original Raft paper works only with uniform nodes, but Paxos variants support proposers without storage and…

I'm keeping a job search diary on my blog

Social engineering dos and don'ts
Another day, another success at sneaking into a building and pretending to be staff. I do so love drinking other people’s expensive office coffee. No fruit bowls though. Close, but no banana.
