Upgraded my computer – Love the NVIDIA GeForce 8800 GT card

I have a couple of computers at home but my primary machine is a DELL desktop running Vista. This is a dual-core machine with 4 GB of RAM but it ran sloooooooooooowwwwww. So I just upgraded the machine with a new 500w power supply and a NVIDIA GeForce 8800 GT video card. The NVIDIA GeForce 8800 GT is an amazing video card that’s SLI ready with 112 stream processors and a 256-bit framebuffer interface running at 900MHz, DirectX 10, PCI Express 2.0 and the second generation NVIDIA PureVideo engine with full acceleration and post processing for HD DVD and Blu-ray movies.

Here are the screenshots of the Performance Information and Tools screen with the before and after Windows Experience Index number. Guess I need to upgrade the processor next.

The power supply I chose was the PC Power and Cooling PPCS500D Silencer.

Holy Bandwidth – Take 3

I just upgraded my existing Road Runner turbo connection to their Business Class service and I now have 15Mbps downstream and 2 Mbps upstream along with QOS to give my packets priority over the rest of the regular Roadrunner customers.

Road Runner Turbo - Business Class bandwidth test

Prior to this upgrade, I was getting 15Mbps downstream and 1 Mbps upstream and so the extra Mbps of upstream is nice but I can really tell the difference in the QOS. I did a speed test to a server in Chicago and then to another server in San Francisco and didn’t notice any drop in speed or overall bandwidth. Prior to business class Road Runner, there was significant drop-off in speed as you traveled further away from my location.

Simple Tags plugin & WordPress 2.5 RC2 breaks your blog

I just upgraded my blog to WordPress 2.5 RC2 and everything stopped working. Instead of getting my blog or the admin screen, I got the following error message:

Fatal error: Call to a member function add_query_var() in taxonomy.php

I discovered the root-cause of the problem and it is the wonderful Simple Tags plugin. Disabling the plugin restores WordPress back to it’s own awesome self. Simple Tags is an awesome plugin that allows you to manage tags within WordPress.

I’ve opened an issue with the Simple Tags issue tracker on Google Code.

Upgraded to WordPress 2.5

I know the latest release of WordPress, v2.5 is not officially out but I have been running WordPress 2.5 from their Subversion repository trunk for about the last week. My initial thoughts on the 2.5 release are very positive and all of my plugins and themes have worked without any major changes. Most plugin and theme authors are already busy upgrading their stuff to the latest code.

Some of the new features include a customizable dashboard, multi-file upload, built-in galleries, one-click plugin upgrades, tag management, built-in Gravatars, full text feeds, and major performance improvements. Apparently, the Automattic crew has been working with the folks at Happy Cog — Jeffrey Zeldman, Jason Santa Maria, and Liz Danzico — to redesign WordPress from the ground-up. The result is a new way of interacting with WordPress that will remain familiar to seasoned users while improving the experience for everyone. It’s more than just a new CSS – it’s a very nice redesign of the user interface that may require a little time to get familiar with, but it’s worth the effort as the new interface is very user-friendly, slick, and powerful.

Do this at your own risk as this is still pre-release software, but if you want to run the latest development trunk of WordPress, use the checkout command (svn co) to get the latest code and then an update once you get the latest code to make sure you are getting the latest code (svn update).
