This Linux tool is my new best friend. We get thousands of XML files from our clients for loading user, class, and enrollment information. Some of these clients customize our software or write their own software for generating the XML. This means we frequently get oddities in the files which cause problems. Thankfully I am…
I missed the story about brothers convicted of harvesting emails the first time. Well, I noticed a followup. Back around 2001, the CIO received complaints about performance for the web server. So, I went log trolling to see what the web server was doing. A single IP dominated the HTTP requests. This one IP passed…

The truth of history means very little to those who are dead set against learning anything from it.

Let’s nevermind why I am working on this in the first place. Namely… the Blackboard Learning Environment Connector introduced using the hostname and port for applet URLs in Vista 8 Blackboard, Blackboard dropped WebCT’s support for using a different port for an application when behind a load balancer. So we found out we could use…
One of the reasons my photos sets are more full of flowers than buildings is people don’t call the FBI over pictures of flowers. While it is perfectly legal to take pictures of buildings from public spaces, it makes “victims” nervous. No one cares about flowers. I can take all the pictures I want without…
