I’ll admit, I’m a bit of a JavaScript n00b when it comes to doing UI development. One of the outside consulting projects that I’m working on is asking me to push the limits of my JavaScript knowledge, and I can definitely say the past couple of days have given me a sad realization that there are some strange oddities to JavaScript development. Once you understand that Prototyping is much like Extension Methods in .Net, that part’s pretty easy. What’s not easy is trying to figure out how to do event handing with Object Oriented classes.

One of the side projects I’m working on involves having users listen to audio files and fill out information in response to the audio files they listen to. Some audio files will be short (e.g. 5 seconds or less), but others may be long, say a few minutes to an hour or longer. These audio files are typically voicemails or ditcations, so people can have a tendency to leave long breaks between words, will talk slowly, etc., thus slowing down the listening process. The goal: figure out a way to allow the users to speed up (or slow down) the audio files as much as they would like without having to process the audio files on the server ahead of time. The possible solution? HTML5

I am setting up monitoring for my PostgreSQL database server, and ran across a cool way to get around specifying the username/password via the command-line every time the checks are run: pg_service.conf. Unfortunately, there is very little documentation on the config file. As best as I can figure out, if you are connecting to a remote host, your definitions should look as follows:
[service.name.here]
dbname=db.name.here
user=user.name.here
host=host.name.here
password=password.here
On a Gentoo Linux server with PostgreSQL 8.4 installed, this file will need to be placed at /etc/postgresql-8.4/pg_service.conf. Then, to reference it, simply export the PGSERVICE environment variable with the value of the name of the service in brackets.

So, I haven’t posted anything really talking about the details of my life in 2009. This is likely attributed to my extremely busy schedule for the majority of the year, amongst being overwhelmed at times with the changes going on that directly and indirectly affect me and my family. I hope to cover the highlights of the year, and then wrap up with great news that has changed Melissa’s and my life forever.

If you were a luck systems administrator who followed the instructions for a Tomcat container installation using the EAR-WAR install when setting up Atlassian JIRA, then you may have been privileged to see the following error message in your log files:

I recently upgraded my student worker workstations up to Snow Leopard (Mac OS X.6) to take advantage of the better integration with Active Directory and Exchange. The primary reason: getting network home drives working correctly. We have a set schedule for them, but they may come in early or late depending on their school schedule. This introduces problems if someone is on a workstation that another typically uses. If all of their data were on a network server, there would be no cause for concern because they could use any workstation and still have access to all of their data. This blog represents my trials and failures with getting mobility synchronization to work properly.

I cannot believe i’ve never seen the first Star Trek: The Next Generation episode. Then again, it first aired in 1987, which would have made me about 3. I have to say, the later years were so much better!! the camera angles, acting, and music were quite campy in the first episodes. Oh, and Riker is really boy-ish. It’s weird.

Many airlines have lowered their maximum weight restrictions, such as Frontier, to just 50 lbs. We found this out this morning when going to Yellowstone when Melissa and I expected to save $15 by using 1 checked bag (because each bag checked after 0 costs). However, this put us only 11 lbs. overweight resulting in a whopping $75 overweight “penalty”. What ever happened to the good ole days where airlines didn’t charge for checked baggage?

After several updates of various systems software packages on my Gentoo Linux servers, I began to notice a problem where I was being denied sudo access. The solution was amazingly simple, once I actually Googled to figure out what was going on.
