I did found a job. And I actually worked... for two days. But, apparently, the shareholders of this company made an abrupt decision and decided to stop some activities. So I was fired, even before doing anything serious. A good example of the kind of communication that occurs sometimes between the shareholders and the executives.
So I'm back at the point where I have to look for a job. Hopefully I'll find a better Unix/Perl job. In the meantime I play golf!
