		<title>MySQL Replication Slave Control shell script</title>
		<description><![CDATA[I set up a replication slave at our office to a MySQL server running at our colo and the master server is pretty busy. So busy that even with the compressed protocol option turned on the stream was taking a good 60-70 kbps out of the available bandwidth of our T1. Since it isn&#8217;t critical [...]]]></description>

		<title>Converting PowerMac G4 to 2U Server</title>
		<description><![CDATA[Many years ago, before there were Xserves, in an attempt to save rack space in our cabinets, we experimented with ripping the guts out of a PowerMac G4 and stuffing them into a 2U server case. Here is a photo of one of those attempts:

It worked out fairly well and we had a couple of [...]]]></description>

		<title>YouTube briefly offline due to Pakistani ISP</title>
		<description><![CDATA[So apparently YouTube, according to a Pakistani telecommunications authority, carries content that is &#8220;deemed offensive to Islam.
So the ISP either purposefully or accidentally, added custom routing configurations to it&#8217;s routers to block YouTube. The unfortuate side-effect was that these BGP announcements were propagated to a large part of the world&#8217;s routers, taking YouTube offline for [...]]]></description>

		<title>Converting disks from Apple Software RAID version 1 to version 2</title>
		<description><![CDATA[We have a few servers that are still running from being upgraded from the 10.2 and 10.3 days. Most all are running Tiger server, with one or two running Leopard.
Since all our XServe G4s run with dual mirrored pairs, we have quite a few of these software RAID sets.
The trick is that if a mirror [...]]]></description>

		<title>Ubuntu/Debian on an Intel MacMini</title>
		<description><![CDATA[In our previous adventures with Mac Minis as &#8220;blade&#8221; servers, I thought we might try installing Ubuntu/Debian on an Intel MacMini and seeing how the system performed against an OS X client based system.
Well, we did that and about a week later we wiped the machine and imaged off one of the other Minis and [...]]]></description>

		<title>OS X - Server Monitor crazy tech note</title>
		<description><![CDATA[Server Monitor is an application that allows you to monitor the health of several Xserves over the network:

Sometimes the application gets a bit cranky about the connections it makes to the servers and reports that it can&#8217;t communicate or as you see here in the picture &#8220;reply not understood&#8221;. So we don&#8217;t really use it [...]]]></description>

		<description><![CDATA[ I forgot that I had my 2GB MicroCenter USB flash drive in the pocket of my sweat pants and they got put into the wash by my wife.
I was searching and searching the whole house trying to find it.
Finally, my wife pulled it out of the dryer, I plugged it into our Philips DVP5982 [...]]]></description>

I had connected in with Remote Desktop Admin with an admin level account and wanted to tighten up some of the controls for who was authorized to connect. Using this screen [...]]]></description>

		<title>Failing 180GB Xserve hard drives</title>
		<description><![CDATA[In the past couple of months, we&#8217;ve started to see the IBM/Hitachi 180 GB drives that came with the Apple Hard drive modules for the Xserve G4 and ATA Xraids fail.
We always have these in a software mirror RAID, so we don&#8217;t have any data loss, but we are proactively starting to replace these drives [...]]]></description>
