I had this quite trivial problem: the version of Go I installed on my pc was quite old.

A client of mine had this problem: they had a very, very old CMS, built in quasi-pure PHP, and quasi-abandoned. Also, part of its codebase was encrypted. It was just garbage.

English abstract: Your webcam works with many programs (aMSN, Camorama…), but Skype? Try to load it with “LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype” (no quotes); your webcam shows dark, wrong, “redshifting” colors?
