⚙️ Want total control over your OS? Build your own Linux distro from scratch. 🐧🛠️

This guide from Linux Journal lays out:
🧱 Core tools — Linux From Scratch (LFS), Yocto, Archiso, Debian Live Build
🔧 Full control of the kernel, init system, and package manager
🎯 Tailor builds for embedded devices, hardened servers, or lean desktop use
💡 Ideal for learning, optimization, and branding

Custom Linux isn’t just for pros — it’s for anyone who wants to know what’s under the hood.

In 2003, an attacker breached a public-facing server and attempted to slip a subtle backdoor into the Linux kernel’s source code. The exploit was deviously simple, a small modification that would grant root access under specific conditions, making it nearly invisible to casual review. However, the Linux development process requires cryptographic signatures and meticulous code auditing. When a routine integrity check flagged an unexpected change, developers quickly investigated and discovered the malicious code before it could ever make it into an official release. This incident became a defining moment in Linux security, proving that while open source code is accessible, its real strength lies in the transparency and scrutiny of its community.

It's never too late for an ambitious goal and to learn something new. I'm reading "Linux Kernel Programming - Second Edition" by Kaiwan N. Billimoria [1]. Chapter two brought back a lot of memories. Glad that "make menuconfig" and the like are still around even after so many years I didn't touch them. Wish me luck on my journey to contribute to the Linux Kernel one day.

tfw when you are happy to see your thing do the exact same thing it did a month ago but ✨️in a different more special way✨️

The last maintainer of the #OpenPsion project is looking for someone to take over the maintenance of this #Linux distro for #Psion Series 5mx.

If anyone is able to help Adrian out, please get in touch.

Is here anyone in the #Fediverse who can act as a delegate/reviewer for the #Linuxkernel? It would be great if this tiny #kernel patch could still make it into the 5.14 kernel: https://patchwork.kernel.org/project/linux-input/list/?series=523049

Without the patch, the #Elantech #trackpoint in the #Thinkpad X13, T14s, etc. keeps jumping to an edge/corner. This drives me crazy. Thanks in advance!
