Where are we going from here? Software engineering needs formal methods
The job of a software engineer is not to produce code, but to solve problems; we just happen to solve most of those problems by producing code. Ultimately, producing code is hard, and we need help. That's why GitHub's Copilot is exciting, but it's far from ideal, and it's the tip of the iceberg of what's been done and…

PipeWire Under the Hood
The PipeWire project is slowly getting popular as it matures. Its documentation is still relatively sparse but is gradually growing.

Whenever its been mentioned, its usually been presented as a new alternative to select, poll and epoll. This led me to believe that it was just the…
