Having created a shell of our app in step 2, porting the image cleaner code in step 3, we’re now at the stage where we can to port our command line XML cleaner code to Qt. At the end of this post we’ll have a fully functioning C++ Qt app.
Porting to the Qt C++ Framework :: Part 3

In this part of our series we’ll dive in and start implementing our logic from the command line application to the GUI version.
The goal during this step is to make exclusive use of the Qt frameworks built-in functions and methods for handling these tasks, as the end result must be a cross-platform compatible app.
We’re already getting a valid directory entry from part 2, so the first step in this part is to figure out how we iterate and query files from our base folder.

In this post I want to introduce the Qt code I’ve written so far. One of the strengths of the Qt framework is its well supported in NetBeans, but more importantly, by Nokia via the Qt Creator IDE. In fact, Nokia supplies a host of tools, from the IDE and language tools, an Interface Designer, and loads of examples.
At the end of this post we’ll have a shell ready for the actual porting process to being. In other words, a GUI that loads, reacts to button presses, and updates status text.

In this post we’ll start the process of porting a simple command line C++ application to the Nokia Qt framework. Well take a quick look at the code in question, then talk about how we’ll port it.
The application in question is a simple tool for cleaning up the export of a Print Publishing CMS system for eventual use in a Web-based CMS. By simple I mean we open a folder and loop through it, diving into sub-folders as needed to:
- Remove all images tagged with a _bw_
- Open XML ‘story’ files and remove extra line breaks from headline elements, and clean up content HTML.
The application started as an Apple Xcode project, and has now moved into NetBeans 6.8 on Linux. In the end I hope to learn a good deal about the Qt framework, as well as proper C++ application development.

The strange thing about this post is that this isn’t exactly news–ever since FireFox 3.5 came out in June of ’09, and along with Safari 4 and Google Chrome using a slightly different mechanism, these browsers all support OS Level multi-threading.
The question is, should you care?
Posix Threads In C++

It’s sometimes hard to find a good example of working with threads in C++. Thus, in the course of implementing a very simple working example I decided it wouldn’t hurt to post what I came up with.
HipHop PHP Benchmark

Update: Looking to try HPHP? Take a peek at my open-source HPHP UI.
What are we looking at?
The chart above shows Ubuntu in a 2 and 8 core configuration (the x2 and x8), along with a Server 2008 instance running a benchmark program to stress a PHP based webserver.
What does it mean? The good folks over at FaceBook recently released a custom tool called HopHop that rewrites PHP into native C++ code. The upshot to this, as you can see, is bare-bones PHP code, that is, code which relies on math and loops and such, is much, much faster. Of course other code should be faster as well, though I have yet to benchmark more complex scripts.
JW Player Playlist Editor GUI

Here’s a simple script for managing/editing playlists in the popular JW Player.
It’s called [ Media Manager For JW Player ], and is GNU General Public License software which means it’s free and anyone can edit it.
That means I hope that this little manager will be of use to someone, but more importantly, may grow into something larger if others want it pick it up and run with it.

* Benchmarks current as as of 2.17.10
Who’s the fastest: Apache on Windows or Apache on Linux?. In the course of deploying a new web server I thought I’d find out. I play around with APC, Database tuning, and so on. Among other things, in the end we see how with a few simple settings we can increase our servers capacity 2 times over.
b2Evo to WordPress Export Script

We recentlly had to convert a few b2Evolution blogs to WordPress 2.8, something that is apparentlly common but not very standardized. Thus, after some digging I found a script, but it did not work with the newest versions of each component.
After a few tweaks I was able to get it working again, and now I would like to share the result with this slightly modified b2Evo to WordPress Import Script:
