Install HandBrake CLI v0.9.9 on CentOS 6.4

This is a quick guide to help you get HandBrakeCLI installed on CentOS 6.x. This was specifically tested with HandBrake v0.9.9 and CentOS v6.4, but it should also work for the future versions as long as nothing major changes.

First, make sure you have the prerequisites installed:

yum groupinstall 'Development Tools' 
yum groupinstall 'Development Libraries' # Ignore for CentOS 6.5
yum install fribidi-devel gtk+ yasm webkitgtk-devel gstreamer-devel gstreamer-plugins-base-devel bzip2-devel
yum install libgudev1-devel libnotify-devel libass-devel libsamplerate-devel libogg-devel libtheora-devel libvorbis-devel

Update Rackspace Cloud Load Balancer Timeout

Here is a simple script to update the Cloud Load Balancer configuration options using the Rackspace API for it. It’s been tested with Python 2.7 and Python 3.3.

I made this primarily to make changing the timeout a little easier(you can’t currently change it from the Cloud Panel), but you can update any of these fields too:

  • name
  • algorithm
  • protocol
  • halfClosed
  • port
  • timeout

Once you have it installed you can run it with the -h flag to get the list of arguments and an example usage:

Compiling php-python on Fedora Linux

So, I haven’t posted in a while, and I felt it was about time to get some fresh content up here so what follows is the result of some research and testing I did as a result of re-visiting a question on SuperUser that I responded to over a year ago that was never fully resolved.

So, you want to run python code in PHP, eh? Why you might ask? Well, I’m not quite sure. I haven’t run in to a use case for it myself, but I can see where you might need to do some heavy-duty maths or maybe there is a python library that you require for some custom algorithm or something.

Good news! There is a PECL library you can use for this task: http://pecl.php.net/package/python
Unfortunately, it hasn’t been updated in over 4 years at the time of this writing and was in alpha at the time of the last release.
However! The maintainer appears to still be working on the package, but over a GitHub: https://github.com/jparise/php-python
Unfortunately, it still doesn’t compile on PHP 5.4 (in Fedora at least)
However! I got it to work with some minor tweaks.

Displaying the version number in Adobe AIR

In the Adobe AIR application descriptor file there are many options you can set. One of which is the tag(or in Flex SDK v4.1 and below), which lets you differentiate your release as well as utilize the Adobe AIR updater library.

It can be useful to display your version number inside of your app to inform the user as well as help with bug reports among other reasons. In order to prevent you from having to update the version number in multiple places you can use AS3 to grab it from the application descriptor and update your text for your app on the fly, as it loads.
