I often run into this issue with people who don’t fully understand the correlation between File Types and File Extensions. Most people just assume that because a file has the extension .doc on the end that that means it is a Word Document file. While this is sort to of true, it is not entirely true. Here is a description of the difference.
I often find that people that are not familiar with virtualization are amazed when I open Windows on my Mac laptop. I figured I would go over virtualization a bit to help get the idea of the technology out there.
Ubuntu packages MySQL with yassl support instead of OpenSSL. These two implementations are incompatible. Recently we found this out at work as Red Hat and OpenSUSE both bundle MySQL with OpenSSL. One of our MySQL servers is running on Red Hat and we were unable to connect using the Ubuntu binary MySQL client. This of course also breaks things like the php-mysql, python-mysql and ruby-mysql libraries as they are compiled against the MySQL client on the distribution.
I decided to start a more professional portion of my website where I can list projects that I work on at home and at work as a portfolio of sorts. I’m using Joomla to run this portion of the site as apposed to WordPress like this blog is run on. This was started when somebody asked me if I knew anything about Joomla, which I did not at the time.

I tend to use my Mac Laptop at work a lot and that has spilled over into using it at home quite often as well. I got tired of having to switch from the keyboard and mouse of my desktop over to the laptop’s keyboard and mouse over and over when I needed to do something on it.
My Coworker at work has a similar setup and told me to try Synergy so I thought I would give it a shot. Essentially Synergy allows you to connect expand screens of any computers onto a single computer.
For example
I put my laptop to the left of my screens at home and want to be able to use the keyboard and mouse from my main computer on my laptop.
Here you can see my dual monitors with my laptop to the left of them
So setting up synergy I can now do this.
While I was super excited to get my new blackberry when I first ordered it(First impressions of it), it slowly started to anger me more and more. The device’s battery is super flaky and would only last about a day and it would periodically lock up completely.
Well since I had a hankering(sorry I just love that word) that the Storm probably just needed some love I tried a few things that seemed to have worked really well and decided to share them
- Apps that continuously pull information down from the Internet kill battery. Make sure you don’t have these running all the time. Here is a list of apps that do this that I use
- Google Talk
- MSN Messenger
- Google Maps
- Gmail
- Google Sync
All of these don’t constantly pull information, but the messenger ones are really the killers. They are in constant communication with a server and will kill your battery the fastest.
- Delete all those crappy blackberry apps. I deleted pretty much every app that I didn’t use.
To delete applications on the Storm I went into Options(icon looks like a wrench)->Advanced Options->Applications
This will list all the apps on your phone. You can highlight an app and then hit the Blackberry button and click Delete to remove it.
You will have to reboot your blackberry after you delete all the apps you want in order to make the deletions take affect. - Delete all old messages. Once I realized that my phone had well over 1000+ stored text messages and other messages I deleted them all. If you use the blackberry mail client as opposed to the Gmail client or whatnot you are storing all your emails on you phone( I think ) which takes up available application memory. Freeing up this memory allows your apps to run without running into memory issues.
Just using these 3 tricks should prevent your blackberry from locking up as much as it was. I suspect there is a memory issue on the phones that creates issues when it doesn’t have enough free memory. I know when I first got my blackberry it was expected that the device would lock up on me at least once a day where I couldn’t even unlock the phone. After doing these three things I have only had 1 lock up.
Haha, XKCD hit this one on the head
If your theme supports the get_header_image or header_image function in wordpress you can modify it so that it uses a Gravatar instead.
Edit the wp-includes/theme.php file and find the function get_header_image and change it so it looks like this
/**
* Retrieve header image for custom header.
*
* @since 2.1.0
* @uses HEADER_IMAGE
*
* @return string
*/
function get_header_image( $gravatar = False ) {
if( !$gravatar )
{
return get_theme_mod(‘header_image’, HEADER_IMAGE);
}
else
{
$email = ”;
$tm = mktime();
return “‘http://www.gravatar.com/avatar.php?gravatar_id=”. md5( strtolower(‘$email” ) ) .”&size=110?antiCache=$tm’” ;
}
}
Then modify the header_image function so it looks like this
/**
* Display header image path.
*
* @since 2.1.0
*/
function header_image( $gravatar = False ) {
echo get_header_image( $gravatar );
}
Now all you have to do is find in your theme where it uses the header_image function or get_header_image and change it so that it just says
header_image( True ) or get_header_image( True ) depending on which one you use(they both do the same, one is just depricated
The image in the upper right is my gravatar
Well I’ve just completed an adventure figuring out sound for Amarok in Gnome under Jaunty and feel it necessary to share the knowledge.
This of course assumes you have Jaunty and Gnome and not Kubuntu(which Amarok will probably work just fine in). Really this might not even matter as I was trying to allow Amarok to play through either my USB headset or my speakers and could not get Amarok to choose the one that I wanted.
Here is how to be able to choose between which one you want
Installation
sudo apt-get install amarok phonon-backend-xine kdebase-workspace
Setup
sudo systemsettings
Then go to Multimedia and you can select whatever audio device you want for KDE to use which in turn is how Amarok decides on how to play its sound.
I had to actually choose gstreamer as the backend device and then switch the hardware preferences in order to switch between my speakers and my USB headset. I see now that it has taken upon itself to switch back to xine, but its working and I don’t care anymore.
