Many nginx setups use php-cgi, so it is critical to patch PHP to the latest version or apply the recommended fixes through Apache Rewrite.
Mod_php and php-fpm systems are not vulnerable to this attack. Most Apache web server setups use the mod_php method for PHP.

If you are running an older version of PHP and cannot update to 5.3, you can try using Apache rewrite rules.

Here are a few alternatives to the GitHub hosting service. There are two types of software: locally installed software and hosted. These are decent for smaller companies that don't have the budget for licensing a hosted service.

Free Local Install

gitlabhq.com - this project looks really good, with new releases every month.
gitorious - solid, free alternative to GitHub.

Free Hosted

gitorious.org - open source projects are free, like github.
bitbucket - unlimited free private repositories for up to 5 users. The pricing model is similar to the other Atlassian products.

To remove Gnome from Scientific Linux, run the following command (while running outside of the GUI). This will remove all related applications related to the Gnome including Mozilla/etc. yum groupremove "GNOME Desktop Environment"

Next, you will need to make sure your runlevel is set to 3. Otherwise, you won't be able to boot up into text mode. The run level in RedHat/CentOS/Fedora/Scientific Linux is set to 5 for Gnome/KDE.

As a Content Management System developer, having a good tree plugin is key to organizing files in directories. With a small number of folders, any jQuery tree plugin will suffice. But, I've encountered some limitations with 1000+ folders and Internet Explorer compatibility. Dynatree is my current favorite jQuery plugin. The code is maintained with very good browser compatibility (IE 8 works without any problems), excellent documentation, and lots of features. Supports checkboxes, drag and drop, persistence, and HTML/JSON/or Javascript data loads. If you have a large number of folders, it is best to use JSON as the data object since you can use AJAX to dynamically load the lists. Even without the "lazy load" option, the script runs fast with a single load of the JSON data.]]> http://albertech.net/2012/03/review-top-jquery-tree-plugins/feed/ 1 Amazon AWS Free Usage Tier http://albertech.net/2012/03/amazon-aws-free-usage-tier/ http://albertech.net/2012/03/amazon-aws-free-usage-tier/#comments Mon, 12 Mar 2012 17:40:21 +0000 admin http://albertech.net/?p=892 Amazon offers new AWS users one year of free usage to their cloud platform.

VMWARE Tools install on Fedora http://albertech.net/2012/02/vmware-tools-install-on-fedora-1/ http://albertech.net/2012/02/vmware-tools-install-on-fedora-1/#comments Tue, 21 Feb 2012 23:49:46 +0000 admin http://albertech.net/?p=881
If you encounter the following error while installing vmware-tools in Fedora:
Searching for a valid kernel header path... The path "" is not valid.
You will need the following packages installed: gcc make kernel-headers kernel-devel The trick is that you will need to perform at least two reboots before the vmware installer will actually find the kernel header package. You can verify the kernel install using "rpm -qa kernel*"
1. yum install gcc make kernel-headers kernel-devel
2. yum update
3. Reboot (shutdown -r now)
4. Run vmware-install.pl (Ex. /tmp/vmware-tools-distrib)
5. It will probably not find the kernel header path this time around. Cancel the installer if its unable to find it again.
6. Reboot (shutdown -r now)
7. Run ... ]]> http://albertech.net/2012/02/vmware-tools-install-on-fedora-1/feed/ 0
