There's a fantastic way to collaborate when writing an academic paper in LaTeX - using Google Docs. LaTeX is all text anyway, so collaborating over GDocs is straightforward, but alas there is no colorization to make it like a good LaTeX editor... Fortunately there's AppScript to help us!

I bet creating searchable PDFs has been done many times over, even so I'd like to share the way I did it recently with strictly open source tools. The pipeline is simple: GS to separate the PDF to pages, tesseract OCR to extract text, hocr2pdf to create a merged PDF and GS again to bundle everything back to unified PDF. If you're creating a PDF from scanned books, this project may also be of help: unpaper

Phew. Finally this is working!
I've been confined to OpenGL 2.1 and GLSL 1.2 on the Mac since the Qt OpenGL context will not pick up the core OpenGL profile (a big problem on it's own) and get an OpenGL 3.x and GLSL 1.5... So it's back to old school GL'ing, but anyway some things are working, albeit they have their quirks.
So for all of you battling the OpenGL 2.1 war, here's how I made VAOs work with a very simple shader.

For those of you still interested, I've made the move to using Qt and QGLViewer in the SfM-Toy-Lib project. Getting rid of PCL dependency (I think it's a bloated library), and burying FLTK long in the past, I feel much better about it now.

So QSerialPort only became part of Qt core on Qt5.1, but what should all those Qt4 projects do for an easy serial port access?
There is the excellent QExtSerialPort project, but it only has a QMake build system, and I like CMake!
Not to worry, a CMake build is easy to set up...

Hi Guys,
After a while we are trying to "lighten" things up. Let us know what you think

I haven't found a CMake module to find FFMPEG libraries, so I wrote one (a while back) and I thought to share it.
It will look very hard in order to find it on *nix and Win all the same, and I found it useful.

I wish to report of a number of tweaks and additions to the hand silhouette tracker I posted a while back. First is the ability for it to "snap" to the object using a simple Active Snake method, another is a more advanced resampling technique (the older tracker always resampled after every frame), and of a number of optimizations to increase the speed (tracker now runs at real-time on a single core).

For those of you using OpenCV that are looking to upgrade from OpenNI 1.x to the new OpenNI 2.x, here's a bit of code to make life a tiny bit easier. It simply wraps the OpenNI 2.x APIs to expose a simple frame grabber for OpenCV.
