What is up with file extensions ending in ar. In a daily and weekly basis I have to deal with tar, jar, rar, war, and ear files. I think we still need a car extension for Nascar fans, and var for the JavaScript web devheads, mar for the Spanish speakers, par for all the golf fans, oh wait EJB 3.0 makes use of a new par extension for its persistence entity beans.. To put everything into perspective I think we still need a far file extension. If I would to come up with a new compression algorithm I would use an extension that denotes my favorite hang out; bar.
