I stumbled upon this most excellent series of posts by Moritz Lenz of perlgeek.de that describe the differences between Perl 5 and the upcoming Perl 6 (thanks to Andy Lester for the link). The posts are done in the form of tutorials, which helps comprehension. Simply awesome, Moritz.
It seems like Perl 6 is going to be a lot more object oriented, but such orientation is optional and not forced upon programmers, like in, say, Java. It warms my heart that I will be able to do this (you did see the new "say" function in Perl 5.10, right?):

my Num $x = 3.4; say
So the other day I was setting up public key authentication for one of my users, which is usually very straightforward: generate a private/public key pair, stick the private key into user's .ssh dir, set dir permissions to 0700, private key permissions to 0600, stick the public key into the authorized_keys file on the server, and the job's done. However, this time, no matter what I was doing, the public key was being rejected or ignored and the system was moving on to the keyboard-interactive authentication.
Debugging on the client side with -v didn't help much:

1. I want to download and play FLVs on my computer.
2. I don't want to use some crappy FLV player that only plays FLVs and has an interface from either 1995 or 2034 – I want to use my favorite player, like Media Player Classic.
3. Yes, VLC plays FLVs but it can't fast forward or rewind them. Yes, mplayer plays FLVs but I want a GUI. Yes, mplayer supports GUIs but they all pretty much suck. I don't particularly like VLC's or mplayer's interface – want to fight about it?
Enter the latest version of ffdshow. ffdshow is a decoding filter – think of it as a set of codecs for your media players. It supports …

According to Wikipedia, in April 2008, the number of videos on Youtube was 83.4 million (ref: http://en.wikipedia.org/wiki/YouTube#cite_note-5). However, the link in the cite note now displays “*” video results 1 – 20 of millions, without showing the real count.
Here's one way I found to get an estimated, but relatively accurate, number of videos on the popular video sharing site Youtube. The idea is simple. Get this feed: http://gdata.youtube.com/feeds/api/videos/-/* and parse out the number inside the <opensearch:totalresults> tag.
So here it is: the number of videos on Youtube is currently fluctuating between about 141 million and 144 million. The number goes up and down, which points to the fact that these are estimates.
That's a whole boatload …
