Star Wars ASCII

I always forget where this is located, so I’m blogging it. Just pop open a shell and type:

telnet towel.blinkenlights.nl

Apparently if you’re using IPv6 it’s in color.

Updating Rubygems

Here’s how I updated my MacBook Pro from Rails 1.2.1 to Rails 1.2.3:

sudo gem update --system
sudo mv /usr/local/lib/ruby/gems/1.8/source_cache ~/tmp
mv ~/.gem/ ~/tmp/
gem sources
sudo gem install rails --include-dependencies

Those five lines of code took about an hour and some serious Googling to figure out. Ah well, back to work.

Update: You may (probably will) get an error after you run “sudo gem install rails—include-dependencies”. I’m not sure exactly why, but running the same command again will finally update your Rails install. Anyone with a better solution should feel free to pop a comment down below.
