Real story:
Started fixing one file in one repo, build, doesn't build, go into other repo fix just one file there, but first I need to make myself a toolchain, making of toolchain fails because it depends on some dirty fix in the file I was fixing, refactor and clean that to a proper state, fuck yeah toolchain builds, source toolchain run make now, breaks with undefined reference, no time to debug plus fuck this automake, remove it, make a makefile, builds fuck yeah, shit now unittest are failing because why not, refactored that makefile as well, everything compiles, automate the test fully so that they are ran on the target out of make just because I'm a nice guy, fuck yeah everything works, commit this repo, commit other repo, review time, one of the guys gave up, the other one did it properly, found some shit there, fix that, done, merge, triggers CI fucking pass

All of this was done in 3h, Talk about efficiency
