Small program to get the current bing "today in bing" image and set it as wallpaper on mate-desktop. Badly written because I reused my first GTK-3 program as a base (that's why you can see some browser references), if you see any problem with licensing, leaks (there are many) or bugs just make a PR or issue.
# zypper install make gtk3-devel libcurl-devel libjson-c-devel
# apt install build-essential libgtk-3-dev libcurl-dev libjson-c-dev
make run
