		<title>Linux Software RAID10 Benchmarks</title>
		<description><![CDATA[Tests are done across four 7200RPM SATAII drives on a PCI (32-bit, 133MB/sec theoretical max) SATA II card, probably the slowest bus configuration possible. Done on Ubuntu 9.10 AMD64 Server.
Benchmark is a simple &#8216;dd&#8217; sequential read and write.

		<title>Replace an LVM Drive with a Larger One</title>
		<description><![CDATA[LVM allows you to hot add devices to expand volume space. It also allows you to hot remove devices, as long as there are enough free extents in the volume group (vgdisplay) to move data around. Here I&#8217;m going to replace a 400 GB drive (sdg) with a 750 GB one (sdf) from logical volume [...]]]></description>

		<title>Start Folding@Home on Boot with Screen on Ubuntu Linux</title>
		<description><![CDATA[Quick instructions to get Folding@home (or any other program) to run at boot before user login on Ubuntu Linux. This probably works on other distros with an rc.local file too.

		<title>Run a Command on Boot for Ubuntu</title>
		<description><![CDATA[I used this to start fetchmail on an Ubuntu 7.10 server running Request Tracker.
Edit /etc/rc.local,  add your command, make sure it doesn&#8217;t create any output. This is my command:
su rt -c &#8220;fetchmail -d 300&#8243; &#62; /dev/null 2&#62;&#38;1
It starts a background fetchmail process as the &#8220;rt&#8221; user, just as the Request Tracker documentation states.

		<description><![CDATA[Dear Intel,
Thank you for including Windows AHCI drivers on floppy disks with your new DQ35JO motherboard. However, putting a floppy disk drive controller on the motherboard would be useful too.
Thanks,
Nick
