Agreed, this wifi stick was mega cheap on AliExpress so I went for it. I may take a look at the PCB in detail if removing it restores order to my PC. Yes, desktop PC (still hanging on to 2012 hardware woohoo!)
I would check for kernel logs from the iwlwifi driver. If there is nothing in dmesg about it failing, maybe see if newer firmware is available for your device?
These LEDs are not shift registers. In fact, if you look closely, there’s no input and output pin, only one data line. That’s because each LED in this strand is pre-addressed from 0 to 100. Whenever it receives the NeoPixel data, it picks out the n’th color data (matching to its pre-address) and displays that. You cannot change the pre-address, its fixed permanently - or at least, we have no idea how to re-address it.
Nothing unsolvable, but it can be a pain when you want to run something not in nixpkgs. My solution is to have Ubuntu on a separate partition, and I was using docker to solve this problem for a while but have moved away from it.
Is my go-to command. For a while I was looking at generations manually, but now I just wait a while (days, a few reboots, or until I need more space) to run this after changing things in case the new stuff is broken.
I think running this as my normal user cleans out old env generations… But I’m not 100% sure.
