When I install CentOS using the XenServer template, it doesn’t allow make any changes to the disk drive configuration. This has two side effects that typically annoy me. First, it calculates an amount of swap space which could be anywhere from 50% to 200% of the amount of RAM you have (I’m not entirely sure […]

Importing a backed up XenServer snapshot is simple, but you’ll need two things to do it. First, you’ll need the UUID of the storage repository that you’ll be importing the snapshot onto. Second, you’ll need the location of the backed up XVA file. To get the UUID of the storage repository, use the sr-list command. […]

I’ve upgraded most of my XenServer instances to version 6.1, so this isn’t as big of a problem as it used to be. With the older version (5.5-ish) there was a problem reclaiming disk space when a snapshot was deleted. Here are the commands that I use to create and delete snapshots. This will output […]

I can’t believe it’s been over two years since I’ve written a blog post. Simply incredible, particularly because it feels like it’s only been a few months. There have been a lot of Flex related developments in the industry during that time, the least of which was being hung out to dry by Adobe. I […]

In Flex you can embed an audio file into your swf (as opposed to streaming it or loading it remotely via a URLRequest). You do that in the same way you embed other assets using the [Embed] metadata tag. To play the sound, you simply instantiate an instance of it, and call play. Optionally you […]

The ActionScript 3.0 reference describes the effects of pixelHinting settings on curves between lines pretty well, but it also affects line segments. Particularly short line segments. The problem is that trying to draw short, thin line segments (1px thick and 3px shorter, or less) will cause the segments to actually appear to be 2px thick. […]

I got one of the Sprint SERO plans for $30/month a few years ago, and it has met all of my needs except my need for a cooler phone. You see, the “unlimited data” plan packaged with my SERO plan isn’t “unlimited” enough to handle the newer (Android) phones. I would have to upgrade at […]

Sean Murphy (my friend and fellow BYU-AUG member) just did a write up of some training he did last month for our user group. It’s an introduction to P2P with Flash+Stratus. In my opinion, this is some really exciting technology as most communication of this sort (for Flash player) has to be routed through an […]

I’ve been using Daemon Tools for as long as I can remember to mount ISO images on Windows. I think it’s an awesome program, I’m sure many would agree. I have no complaints other than the fact that I haven’t been able to get it to work on Windows 7. I’ve started using SlySoft’s Virtual […]

The versatility of the client-server architecture has always fascinated me. You can write a server once, and plug in whatever protocol you happen to be implementing. The same goes for clients. I’m going to present here a simple server I implemented in C++. I guess if I had to give a name to the protocol […]
