Installing security cameras

I had the pleasure of installing video cameras over the last couple of weekends. Overall it was challenging work but a welcomed break from sitting in front of a computer screen. Most of the job wasn't too difficult and wasn't too time consuming.

Fixing a stalling HP USB printer in Ubuntu 10.04

I had struggled with a very frustrating problem when printing to my USB HP Deskjet printer using Ubuntu. The printer would sometimes print an entire job then refuse to print any more after that. The documents would show in the queue but you could not cancel or release them. 
 
Another symptom of the problem would be tasks on the machine, owned by a user lp, that you could not kill. These were USB print jobs that also caused a high load average although the machine performance was not affected. These conditions would sometimes persist between reboots.

Working hard on my goals

In being so busy and wanting to achieve so much, I have managed to find more time to work towards my goals without sacrificing time with my family who are the most important to me. 

Time management is an art and a habit. Rarely can I take time to type up a blog or watch TV, but I have never been so productive and so filled with purpose.

SQL Server connection problems

I ran into a problem whereby my SQL Server jobs wouldn't run. I received this warning in the log:

The program sqlservr.exe, with the assigned process ID 4724, could not authenticate locally by using the target name MSSQLSvc/dev2.[DOMAIN]:[PORT]. The target name used is not valid. A target name should refer to one of the local computer names, for example, the DNS host name. Try a different target name.

I also saw this message:

The login is from an untrusted domain and cannot be used with Windows authentication.

Display templates (partial views) in MVC 3 using Razor

http://stackoverflow.com/questions/6365633/what-is-the-html-displayfor-s...

This is an excellent, easy way to have a consistent user interface. You can use display templates to default values, or give all the values of a specific type the same look and feel (or do both). For example, creating the view String.cshtml inside Views -> Shared -> DisplayTemplates will affect all strings that are rendered using:


@Html.DisplayFor()
