The easiest solution I’ve found is to simply install Ruby and it’s dependencies and then install RubyGems from source.

I’ve written a small script which installs Ruby and it’s dependencies.  It then grabs the RubyGems source tarball and installs Gems from source.  As I wrote this to get a working Chef install, it also adds an opscode gems source.

You can get the script here.

echo "hi" | mail -s "My Subject" to@someone.com -- -f from@someone.com

One thing that is really cool is you can visit the personas gallery and see a bunch of different personas and when you hover your cursor over a persona, your browser will temporarily use that persona.  If you want to use that persona now, just click on it and it’s your active persona.

Here’s a quick little clip that shows what Personas does.

If anyone else has this problem, just apply the following patch to the configure script:

Wow, I wonder if any of our server have been bitten by this nasty Perl bug.  It’s hard to believe that RedHat has taken so long to provide a fix for this problem.

A user had 2 partitions on different hard drives that he wanted to combine the space on.  Ok, well the interesting part was one persons reply about a new fuse filesystem called mhddfs.  He pointed out an article on debian.net that explained a bit about this new filesystem and how to use it.

Sure, there’s multiple ways to combine the two drives, but this one is pretty intesting.  You can use mhddfs to combine 2 partitions into one virtual partition.  Mhddfs will automatically merge (overlay) the contents of both partitions so it looks like one big partition.

The advantages are:

1. No need to move and backup existing data on the partitions.
2. Easily implemented in fuse.
3. Allows a regular user to mount and unmount the filesystem.

According to the forum thread poster, his tests show there is virtually no speed difference when using mhddfs, which is very surprising.  My experience with using fuse in the past with NTFS, was that it was painfully slow.  I’m sure things have matured greatly since I tried it a few years ago.

So, in doing some googling, I found a website that has a patch for moc support and also mentions that it’s been in Conky since September 28th!  I guess they haven’t updated the documentation yet.

Here’s a list of the new variables you can use in your conkyrc file to add moc support.

• $moc_state: Current state of MOC; playing, stopped etc.
• $moc_file: File name of the current MOC song.
• $moc_title: Title of the current MOC song.
• $moc_artist: Artist of the current MOC song.
• $moc_song: The current song name being played in MOC.
• $moc_album: Album of the current MOC song.
• $moc_totaltime: Total length of the current MOC song.
• $moc_timeleft: Time left in the current MOC song
• $moc_curtime: Current time of the current MOC song.
• $moc_bitrate: Bitrate in the current MOC song.
• $moc_rate: Rate of the current MOC song.

Daniel Robbins Funtoo site now has some articles on it that he recently created.  Right now, he has posted some of the articles that we’ve previously seen on the IBM Developer Works website, but there’s also now a quide for installing Funtoo.
