Updating the firmware of the PSLab v6 the way it is decribed on https://github.com/fossasia/pslab-firmware did not work for me. I used mcbootflash instead, which is installed as a dependency of the pslab Python library:
./mcbootflash --port /dev/serial/by-id/usb-Silicon_Labs_CP2102N_USB_to_UART_Bridge_Controller_5ecc207eeba8eb11828e98374232452f-if00-port0 -b 460800 ~/Downloads/pslab-firmware_v6.hex
The ID is individual for each board.

Running "Giana Sisters Twisted Dreams" on a Windows 10 System with Integrated Graphics
January 24, 2023 - Reading time: 2 minutes
Several years ago I bought "Giana Sisters Twisted Dreams". It ran fine on Windows 8.1, but it crashed after I upgraded to Windows 10. I contacted the support of Black Forest Games. The person answering my email told me that the game does not run very well with the integrated graphics of my system (Intel 4600). He advised me to try some different graphics settings which fixed the issue. I basically switched from DX10 to DX9 and turned down the graphics quality.
Restarting I2C when touchpad is not working
January 11, 2022 - Reading time: ~1 minute
After I replaced the Clickpad of my Lenovo L440 with a touchpad (see https://mastodon.xyz/@nause_marc/107111989617471186) the Touchpad would not work occasionally under Debian when returning from suspend. I created a small script called restarti2c.sh with the following content:
sudo /sbin/rmmod i2c_i801 && sudo /sbin/modprobe i2c_i801
This restarts the I2C bus kernel module, which makes the touchpad work again. I run it whenever necessary.
