Linus pulls a (refreshing) 180 on his long history of 'flippant email attacks'

I did not see this coming. Linus Torvalds, writing to the Linux Kernel mailing list: I need to change some of my behavior, and I want to apologize to the people that my personal behavior hurt and possibly drove away from kernel development entirely. I am going to take time off and get some assistance on how to understand people’s emotions and respond appropriately. Introspection is hard, especially when you don’t like what you see after staring yourself in the mirror. Cheers to him for owning up to mistreating others and attempting to change. Here’s hoping he follows through. 🤞

Learn OS development using the Linux kernel and a Raspberry Pi

This repository contains a step-by-step guide that teaches how to create a simple operating system (OS) kernel from scratch. I call this OS Raspberry Pi OS or just RPi OS. The RPi OS source code is largely based on Linux kernel, but the OS has very limited functionality and supports only Raspberry PI 3. 6 lessons available with 5 more on the roadmap.

Hackers have turned the Nintendo Switch into a functional Linux tablet

Paul Miller: There are two major reasons I can think of to hack a game console. The first one is obvious: so you can play cracked copies of games. That’s why modern consoles are so difficult to hack, because millions of dollars are on the line. But some people just want to run any software they choose on the hardware they own. And for those people, Linux on the Switch is a huge achievement. This hack boasts touchscreen support, a fully operational death star web browser, and a GPU-powered demo app. Sadly, there are no details out on how you can do it yourself, but Twitter user fail0verlow has a nice video of it in action embedded in a tweet.

How do you spy on a program running in a container?

Julia Evans: Yesterday I added Linux container support to rbspy, so that an instance of rbspy running on the host machine can profile Ruby programs running in containers… I thought it would be fun to explain what adding “container support” involves in practice! (rbspy is her sampling profiler for Ruby.) This bit is interesting, and why this post isn’t tagged with the Docker topic: We didn’t need to care about Docker or anything like that – it’s irrelevant what container runtime our containers are using, and we certainly don’t interact with Docker at all. I guess a few simple syscalls is all it takes!
