Disable Geo Tagging on the HTC Evo

I recently learned that most common smart phones do something called geotagging. As people who regularly follow this site will know I have recently been doing a lot of work with a new HTC Evo so I was really interested in this. Geotagging, also called geocoding, is the process of assigning geographic location metadata to a photo. The geographic information can include details such as the latitude and longitude coordinates or city and state details for the geographic location of the photo. I may write a later article on how to actually extract the metadata from a picture however for this post I will just show how to turn it off.

Use JavaScript To Require Data To Be Entered Into A Form Field Before It Can Be Submitted

I needed a simple way to require data in a form field before it could be submitted. There are chunks of JavaScript code all of the Internet that allow you to do this easily so I selected one and added it to my form with ease. One small issue I had was it required that the name attribute be modified for it to work which caused an issue with the application I was adding it to. The issue was the name attribute was modified thus it would not save the data to the proper database table column. Below I explain how to add this bit of JavaScript to your form and modify your form for it to function properly.
