Compressing Video File Size

These two sites have been recommended to me to reduce file size media-convert.com and zamzar.com. Sometimes that's necessary to upload video to some web sites.

Valid HTML Code is Better Than Invalid Code

Valid HTML code will look better more places, function as designed more often and be well liked by things like search engines. The W3C Markup Validation Service is a good one since they are the organization that maintains the specifications.

Conditional Comments in Internet Explorer

Conditional comments allow you to have one block of code for some versions of IE and a different block of code for everything else. I've found that IE 5.2 for mac, for instance, does not support conditional comments, but IE 5 through IE 7 on windows seem to support conditional comments.

This code loaded in a browser will tell you whether or not it supports conditional comments:

<!--[if IE]><p>You are using an Internet Explorer that supports conditional comments.</p><![endif]-->
<![if !IE]><p>You are not using an Internet Explorer that supports conditional comments.</p><![endif]>

I recommend using it on live sites sparingly.

Redirecting Web Pages Using PHP

You can redirect the root level of your site http://www.example.com/ to a lower level webpage like http://www.example.com/directory1/directory2/filename.html ) in many ways.

One way to make such a redirection, if you have a Linux hosting plan with GoDaddy, is to make a text file named "index.php" and have the file contain:

 <?php
//Redirect browser
header("Location: http://www.example.com/directory1/directory2/filename.html");
?>
 

Place it in the root of the "web/" directory in your hosting space and, barring a lot of complex configuration changes that may have been made previously, it should gentle redirect web visitors from http://www.example.com/ to http://www.example.com/directory1/directory2/filename.html .

Get Twitter Direct Messages as txts

You can have twitter send DMs to your cell phone as text messages (SMS). Go to http://twitter.com/devices and set-up your phone. Remember to set up the times you do not want texts (or else it may wake you, interrupt work, etc.).

You can also have people's tweets come to your phone as texts (their public tweets, in addition to DMs). After your phone is set up, go to their twitter page (http://twitter.com/[their twitter name]) when logged in, and below their name on the left, change the "Device updates" next to where it says "following".
