Tascam US-4x4HR linux config utility
A while ago I was trying to bring up the sound card Tascam US-4x4HR on a linux server. Linux usb sound module was functional, but the card was mixing the inputs, and I didn't wanted that. After hours of searching through the Internet, I haven't found anything usable, and resorted to "sniffing" the usb control transfers of the official windows utility, and reproducing them with libusb on linux. Surprisingly, it worked well. Here is the link to the potascam github repo. Quick and dirty, as usual.

Qt5 cross-compilation environment for Raspberry Pi
This post is a brief extract of a wonderfully detailed video made by Ulas Dikme. Many thanks to Ulas for sharing his experiences, it saved me several days of work setting up the cross-compilation environment.
Ulas was using an Ubuntu 20 Virtual Box machine for building a sysroot and qt base. While it's not the best solution performance-wise, it's certainly very convenient in terms of being portable across the host machines. My Qt5 build system resides on a USB hard drive.
