I bought a WiPy 2.0 from pycom and noticed, that the documentation assumes you also bought the expansion board (which I didn’t). The board has some components but most of them are for the SD card support or the LiPo charger. An (older?) version of the board is documented here.
What you really need is only some sort of power supply and a USB serial (3.3V). The pinout of the WiPy board is here
I connected a spare ESP8266 programmer to the RX and TX ports and used another USB port for the 5V supply. You can also power the board with 3.3V via the 3.3V pin, but you need at least 500mA (more info).
After the last archlinux update, my cursor was about 3 to 4 times bigger than normal. First it only occurred in skype, but after a reboot it affected the cursor everywhere.
After searching a bit I found this post in the Arch Linux forum. The most practical answer is to comment out the Inherits=Adwaita, which is set through new dependencies:
Then restart X and your cursor should be normal again. The problem only occurs, when no other theme is set, so it’s likely that only users with basic/uncommon display environments are affected (like in my case xmonad).
