Hi All,

I was checking the PRWeb site and here is what I found

http://www.prweb.com/releases/2009/04/prweb2372284.htm

Yes it really works!!! I learned a lot from this press release.

This test press release has only one goal to inform us that PRWeb testing has been successful.

Have you seen this error message:

root@ubuntu:/media/cdrom# ./VBoxLinuxAdditions-x86.run
Verifying archive integrity... All good.
Uncompressing VirtualBox 2.1.4 Guest Additions for Linux installation...........................................................................................................................................................................................................

Please install the build and header files for your current Linux kernel.
The current kernel version is 2.6.27-11-server
Problems were found which would prevent the Guest Additions from installing.
Please correct these problems and try again.

Solution:

or

Have you seen this message lately ?

csvn: Commit failed (details follow):
svn: Could not use external editor to fetch log message; consider setting the $SVN_EDITOR environment variable or using the --message (-m) or --file (-F) options
svn: None of the environment variables SVN_EDITOR, VISUAL or EDITOR is set, and no 'editor-cmd' run-time configuration option was found

Here is how to export SVN_EDITOR variable.

Feel free to change the editor to pico, nano etc.

echo export SVN_EDITOR=vi >> ~/.bash_profile

Logout and then Login again to *see* the change.
By *see* I mean that you have to do execute the following command and the editor of your choice should be run for you:

svn ci

I was checking a post about 8 Most Creative Wallets.

The cool thing is that the site gives you interesting information AND also links with their affiliate link.

That's a genial idea.

I was constantly refreshing to see who is going to win the competition by receiving 1 million twitter followers.

It's between Ashton Kutcher and CNN Network

I am supporting Ashton. By the way his film with Cameron Diaz was pretty cool.

When I refreshed I saw Ashton's followers jumped to almost 2m and then went back to ~990 000.

Twitter definitely is having hard time calculating the real number of the followers.

Sometimes you don't need users to select some of the options in the HTML drop down menu.

For example you have a dropdown menu with these options.

==========================
Please select a province/state for US/Canada

Canada
--------------
Prov1
...
Prov10

United States
--------------
State1
...
State50
==========================

What we need is a province/state but what if the user selects the separators '----' ? or the country name ?

To solve this challenge we use negative values for values that should not be selected. Then using jQuery we disable them.

<script type="text/javascript">
jQuery(document).ready(function() {
jQuery("#acc_info select option").each(function (index, obj) {
// Disable items that have a value less then 0 OR an empty string
// We want those elementes to be disabled only.
if (jQuery(obj).val() == '' || jQuery(obj).val() <= 0) {
jQuery(obj).attr("disabled", "disabled");
}
});
});
</script>

I just checked what headphones are available at bose.ca

Look at the quality of the pictures. Click the following link and then Photos

Having so high quality pictures gives the user a great experience.
