XSLT is pretty neato. You can do basic operations (looping, comparisions, math, etc) with the intention of translating XML into something else, such as HTML.
I got bored tonight and decided to play with it and the results are kinda neato.
Some links to an awesome tutorial on XSLT (and XPath):

Anyhoo, check it out:

Holy christ... I've never had so much trouble getting something to work in my life. For the past several hours of scouring google and online book resources I was left without any working means by which to use javax.net.ssl usefully - and by usefully I mean without requiring a pregenerated key certificate, etc. After looking at SSLSocket.getSupportedCipherSuites() and seeing DH_ prefixes on some of the supported ciphers but not on the enabled-by-default ciphers, I looked into what the DH stood for. Turns out it stands for Diffie-Hellman which I knew to be a secret key generation method: My salvation was at hand. For those who are still in the dark, Diffie-Hellman key exchange allows both parties (server and client) to negotiate a secret key across the wire, cancelling my need for a stored, pregenerated key certificate.

Anyhoo, so the past few hours have been totally not awesome. Here's the fix to get SSLSockets to play kosher with eachother without the need for a certificate:

socket.setEnabledCipherSuites(socket.getSupportedCipherSuites());

Do this for both sockets (server AND client) and they will eventually negotiate upon the Diffie-Hellman key exchange, and you can go about your merry way on the happy SSLSocket-land.

I'm so tired :( Want a good example? Here

My hatred for other people's indenting habbits has now been calmed by the awesomeness that is vim. The command, =, will let you reindent the current line (or the whole file, or whatever) to the settings you use in vim already.
So, instead of dealing with people being dumb and using spaces for *everything* this magical keystroke series will fix my woes:

1G=G

This will cause reindentation of every line in the file you are editing.

Woot.

I got bored and thought this atleast marginally useful:

my @foo = qw(just another perl monkey);
my $x = 0;
print join("\n",map { $x++ . ": $_" } @foo);

The output is:

0: just
1: another
2: perl
3: monkey

If you don't know how to use map() then learn, it makes doing large operations on hashes or arrays brutally simple.
