If you believe it is possible to become an expert in regular expressions as they exist in modern computer languages in "a couple of hours at best" you are delusional.
Every company I've worked at had a responsible person who was the only one able to push code into production. If you allow anyone to do that you are an idiot.
I worked at a small tech company that was bought by a large company. They sent a patent attorney to talk to us. He said to send his office anything that might be patentable. He said that patents for big companies were kind of mutually assured destruction in the sense that if someone sued us over infringing on one of their patents if we had enough patents they were probably infringing one of ours.
A major problem for the A380 is that it is too large for the gates at most airports and the airports have little incentive to build up for just a few flights.
Python was never intended to replace Perl. Perl was designed to extract stuff from text files. Python was designed as a scripting language for system programming. IM(Seldom Humble)O Python beat Perl for two reasons (a) batteries included (CPAN became a clusterfuck) (b) C API lead to stuff like SciPy, NumPy and Pandas.
FWIW I've used both Perl and Python professionally and Python rules.
Over the years I've written too many awk one liners to count. Most of them look ugly - hell awk makes Perl look elegant - but having awk in your toolkit means that you don't have to drop out of the shell to extract some weird shit out of a text stream. Thanks Aho Weinberger and Kernigan!
I don't find anything in your postings to be reassuring. To say that the regulators will be too busy to mess with my blog won't be of use to me the day they do choose to mess with my blog.
