Oholoh is a site that keeps code statistics of open-source projetcs. It’s very interesting to browse though the different projects and look at their metrics.

It can also be a nice incentive to get people do commit on a regular basis, as it adds a sort of healthy competition to the development cycle.

Anyhow…. Great idea, and it already keeps track of quite a number of projects.

That’s all I have to say!

A few months ago, I decided to write a “quick” introduction to the LAB color space.
But instead of just writing the “hey! look, I can increase the luminosity of my image without losing color information”-type of post, I decided to get intimate with LAB and make the fuzzier concepts (the A and the B) a bit easier to understand using practical examples.

The reason why I still haven’t written more about LAB is simple. I got hooked! The more I read about LAB the more I am intrigues by the possibilities and the more I read about it. It’s a vicious circle.

I am now working on my 3rd attempt of the first example (yes, the usual-luminosity-suspect 😉 ) and I am still not quite satisfied. My recent discovery is how stupidly easy one can fix a color-cast in an image with LAB. With this technique you can even get rid of light fog or haze.

However, creating, and annotating, the example images is very time-consuming. And until end of summer I am still very busy, so I will have to postpone my posts a few months 😐

Stay tuned!

My preferred way to deploy python applications on Windows is to use py2exe.

py2exe is a Python Distutils extension which converts Python scripts into executable Windows programs, able to run without requiring a Python installation.

If you run in trouble with sip, read on…

I create a small Flickr API interface for PHP5 which takes advantage of the Overloading feature of PHP5.

Using the __call method we can dynamically create an interface to all the Flickr API functions using only a very small script.

The name of the class is purely ironic as it is a very simple and easy-to-use class and far from Overkill.

Writing Qt apps in Python with Qt3 worked. Somewhat. I never found the energy to get it all set up. Finally with Qt4 we have something that “just works”. At least on Ubuntu and Windows (haven’t tested anywhere else).

Yes, since version 4, trolltech finally decided to release Qt as well under the GPL. To most of you it’s all old news. But hey…. just felt like writing it down again 😉

The problems with SIP are finally gone. So you just install python, Qt4 and pyqt4 and off you go.
