A collection of Forum Posts I Don't Want to Sink into Oblivion

Sometimes I get a creative kick when writing a reply on some forum, and then I feel a little sorry to think that this "gem" will soon be forgotten and unfindable. So I decided to copy-paste some of these outbursts to a dedicated page. It's a little narcissistic. Intel video drivers and configuration.....

Setting up a ThinkPad x250 with Linux

Device encryption, performance considerations W.....

I have no use for this watchdog on a desktop computer. This link already contains all the information required to disable it, but here's the m.....

Record system audio output with ALSA

This was written & tested on an Archlinux system, but I believe it applies to most Linux/ALSA systems. ALSA loopback device We assume a single run-of-the-mill Intel sound card, mapped as card 0. We will create a virtual loopback card 1. #> modprobe snd-aloop aplay -l The loopback device works.....
