Edit Picture Metadata With exiv2

Have you ever uploaded your pictures from a camera only to find out that the your cameras dates and times had reset to the wrong date? Then, have you ever wanted to change images metadata to the correct dates and times? This is a problem that I encounter every once in a while and it usually becomes a chore to find a utility to change this data. I've discovered a great command line program to fix all your metadata problems, exiv2.

Hyndman Tree Farm Website

Over the weekend I created a custom theme for the Hyndman Tree Farm website. I used a similar approach as I did on my site. I used Colour Lovers again to find a pallet that fit the site nicely. Still has some minor issues to work on but, for the most part, I am happy with it.

Hustle For Your Health 5K

This morning my fiancée, Monica, and I ran in our first 5K, St. Louis University's Hustle For Your Health. Since moving to St. Louis in May, we have been trying to live a healthier lifestyle. Along with dieting, we have been exercising 3-5 times a week. Usually we run about 1.5 miles and occasionally 3 miles.

Being a little on the heavier side, I didn't expect anything amazing. My goal was to run the entire 5K without walking. I completed my goal and got a time of 26:23. I can't wait to run another.

Fixing Audio in Ubuntu

A major problem that I have had for a while in Ubuntu has been the audio, especially when flash is involved. If I go to a web page that plays flash (e.g. youtube.com) Firefox takes control over all the audio on my computer. All other audio on the computer stops working. This is extremely annoying. One way to fix this is to close Firefox, but it sometimes takes a few minuets or it doesn't fix the problem at all.

Using the command "ps -aux | grep audio" showed me that a program pulseaudio is running. For a while I though pulseaudio was the problem because running "killall pulseaudio" would fix the problem. After doing some research I realized that pulesaudio is actually a powerful tool that I have just scratched the surface. By changed the "Audio output module" in VLC to "Pulseaudio audio output" I no longer have this problem between flash in Firefox and audio in VLC. Unfortunately I couldn't fix this problem with Amarok or Songbird, but this is at least a start. I will continue to investigate into this problem.
