IT manuals (mostly programming)
Yes it takes a lot of time (in my case almost 5 hours) to get into the goog search manuals and goog appengine. But that’s ok goog is doing fine.
#!/usr/bin/ruby host_port = ARGV[0] host = host_port.split(':').first port = host_port.split(':').last puts %x[nmap -p #{port} #{host}]
Or just:
#!/usr/bin/ruby puts %x[nmap -p #{ARGV[0].split(':').reverse.join(' ')}]
Usage (cli and given that the script is named scan_proxy):

All of us (the people that hate vista and apple styled aliased fonts) have seen the ugly fonts in some KDE apps (Firefox for example). But this is not the case with XFCE where evreything works fine.
So here is a fix for KDE (just run the following command):
$ cat ~/.gtkrc-2.0
gtk-font-name = "Arial 10"
#!/usr/bin/env ruby class Hash def search(arg) self.select { |k,v| k =~ /#{arg}/ or v =~ /#{arg}/ } end end search = ARGV[0] search =~ /^[0-9]+/ and search = search.to_i phones = { "me" => "359880101020406", "Hitler" => "+49 666", "Van Gog" => "+31", "devil" => "666", "God" => "1", } phones.search(search).each do |person| print "person:#{person.first}\tnumber:#{person.last}\n" end
Technology, which is prohibited by the Geneva Convention. Unfortunately, there are still countries in the world where such technology is used to torture animals and developers.
According to the FMI study, 23 monkeys may make random chatter on the keypad to write the language compiler for a maximum of 292 hours.

Thank to Opera plugins’ implementaion I had over 100% CPU laod (dual core).
The solution: rm /usr/lib/opera/9.52/operaplugincwrapper
