Confession time: I still hoard mech keyboards It’s been more than a year since I last posted here (things got… complicated). Incidentally, the last post was about getting the Azio Retro Compact Keyboard to work properly under Linux. Well, I still have this thing for mechanical keyboards, only now I have one extra keyboard, another one on the way and yet another one that I’m dead set on buyin...

Confession time: I hoard mech keyboards So I have this thing (call it a slight obsession) for mechanical keyboards. I’m fascinated by them. My daily driver until now was a 60% keyboard (a Filco Minila with MX Browns) but in the past I’ve used a few IBM Model Ms on a daily basis, especially my cherished “little” SSK. I also have a Unicomp with custom Tux keycaps and another Filco Minila with...

Suppose you have two directories old and new containing the same files, but some of them have changed in the new directory. Further suppose that source control is not used :scream: This post explains how to detect the modified files based on their MD5 sums through a simple bash script. For this example, suppose the file types we are interested in are Python scripts (.py files). Note that we de...

Enabling USB and serial devices in a VirtualBox VM is not straightforward. For reference, the host is a Manjaro Linux machine and the guest OS is a Ubuntu VM. Enable USB 2.0 and USB 3.0 controllers In order for VirtualBox to propose USB 2.0 and 3.0 controllers for the VM, install the virtualbox-ext-oracle extension package. Configure serial ports on the VM If the device that the guest VM ne...

AudioPulse has died on me. RIP PulseAudio. I can no longer select the A2DP profile for my bluetooth headset (Sony WH-1000XM4) under Manjaro Linux. I tried everything: switching between kernels (5.15 through 5.17), the ArchLinux wiki and demon worshipping among others, but nothing helped. “No A2DP profile” means that everything sounds as if coming out of a tin can (also known as HSP/HFP, i.e. h...
