Plurrrr

For every web app I work on, a database client is always present for exploring data and building complex queries. Recently, I have moved on from my PgAdmin to org-mode for this purpose, because why not.

In order to better understand how the garbage collector works, I decided to trace its low-level behavior on a live application. In this investigation, I'll instrument the Go garbage collector with eBPF uprobes.

The inetd ‘super-server’ is a special application which ties incoming network connections to locally-run commands. Using a single super-server to handle all network requests conserves memory and CPU resources at the expense of increased application latency. Although inetd has largely fallen out of fashion today, it was the most common method for handling network requests in the early days of the Internet.
