gollark: I mean, I don't like C very much (as a general application programming language) because it is very unsafe, but unlike PHP it actually has... some amount of design.
gollark: * bad
gollark: PHP is the enemy of mankind. PHP must be destroyed at all costs. Unless the costs involve using COBOL or something.
gollark: It's the internet. Roving bot things are automatically scanning probably every publicly routable device and trying exploits constantly (my webserver logs are filled with what looks like exploits on poorly designed PHP/CGI applications). Don't make their job easier.
gollark: <@428037846721626123> How could you possibly think that an internet-exposed anonymous FTP server was a good idea?
