After buying my iPod Touch and playing a little with it, I realised that battery life was a problem, with the WiFi always on. Thus, I was always bringing up Settins-WiFi and turning on and off. There was no easy and quick way to do it… Until I jailbroke it. I installed SBSettings, and its first use was that. Swipe the upper status bar, and the menu shown above appears.

I am working in my free time in an image processing related program, and this made me remember when I was taking a course in Signal Processing. One of the standard test images was the one above. Where does this historical image processing snippet come from?
Turns out (wikipedia link) it is a standard folklore image, dating back to the seventies, when a bunch of electrical engineers needed an image satisfying certain signal problems (it is, indeed, an image with a lot of significative details, when compressing, denoising or whatever: the hat, the uniform colour distribution except for a few patches of different color…).
Maybe the best coffee time cookies?

Snickerdoodles are probably the best coffee time cookies I have eaten, and also one of the simplest cookie recipes to do. What you’ll need:
125 gr butter
110 gr sugar (+ 1 big spoon later)
1 egg, lightly beaten
1 teaspoon vanilla extract (or change some sugar for vanillated sugar)
250 gr flour
A LISP random triangle generator. Also wrote a C version.
As I said in a previous post, I am looking for some way to detect copied code. I have now a working prototype of a “code juicer”. From a C file it creates a set of PostScript files (well, almost, as they need postprocessing) which are later processed and selected to print. As an example, here is the output applied to a Runge-Kutta-Fehlberg 4-5.
It is something like an execution tree, with function calls squared, and different slopes for if, for, while clauses.
The free iPod stand
Right: middle line, left top line
In this post I will explain how to recycle an old credit card to build a stand for your iPod touch / iPhone. You can choose from 3 designs, depending on your preferred inclination.
Here is what you will need:
