Httptap - Monitor All HTTP and HTTPS Connections of Any Linux Application

by: LHB Community Tue, 11 Feb 2025 15:57:18 +0530 As an alert Linux sysadmin, you may want to monitor web traffic for specific services. Here's why? Telemetry detection: Some tools with sensitive user data go online when they shouldn't. Good examples are offline wallet or note-taking applications. Application debugging when something goes wrong. High traffic usage: 4G or 5G connections are usually limited, so it's better for the wallet to stay within the limits. The situation becomes complicate

Container query units: cqi and cqb

by: Geoff Graham Thu, 06 Feb 2025 15:29:35 +0000 A little gem from Kevin Powell’s “HTML & CSS Tip of the Week” website, reminding us that using container queries opens up container query units for sizing things based on the size of the queried container. So, 1cqi is equivalent to 1% of the container’s inline size, and 1cqb is equal to 1% of the container’s block size. I’d be remiss not to mention the cqmin and cqmax units, which evaluate either the container’s inline or block si

The annoyance is that Linux will still show up in the UEFI boot settings. Although it doesn't hurt to leave it there, it triggers some sort of OCD in me to get a pristine system w
