Those nasty little dot files… When I tried to setup a Gitlab continuous deployment, I encountered a tiny problem: How to remove all files within a Linux directory? Apparently it is quite easy. Just with a simple rm -rf dir/* Wrong! The above command rm -r dir/* only remove all visible files and directories from the directory dir.

Installing new Arch Linux machines are always delightful. Customization, lightweight, and maximum performance. However, in my career of installing 5 Arch Linux servers, there is this one server that always seems fishy. When zsh-autosuggestions tries to suggest past commands, the terminal’s cursor always gets messed up and starts to glitch everywhere.

GPG and pacman errors are annoying So, I was trying ungleich.ch’s IPv6 VPS. It is apparently cheap, and I wanted to host a Matrix server of some sort. It does come preinstalled with Arch Linux, which is good. That means I can get the latest software without relying Docker.

So I was testing some code on my loyal Raspberry Pi 4, ver. 1.2. The Pi is directly connected to my router in another room. Cuz, like, Pi’s ethernet is so much more stable than its wireless. The downside is that every time the Pi had an issue, I had to run over to the other room to recover it.
