Overview about Kinect Frameworks

admin — Wed, 21 Mar 2012 21:12:32 +0000

After searching through the internet, I haven’t found any overview about SDKs for Kinect hacking. Below I’v listed a couple of links (grouped by driver).

Based on the PrimeSense driver:

Microsoft SDK (Microsoft official SDK)
OpenNI (open natural interaction framework)

Based on the open source driver:

VRUI SDK (Virtual Reality User Interface SDK)
libfreenect/Openkinect (origin open source SDK)
CL NUI Platform (Code laboratories Platform)

Interesting stuff to read

admin — Sat, 03 Mar 2012 16:57:11 +0000

Hey folks, at the moment I’m refreshing myself from the testing phase (at the university). After that I will hack ahead with some cool projects I’m currently working on. This projects cover some artificial intelligence aspects and so one. I will write some articles about that on cip-labs. I will also continue my web-performance series. But, let’s switch to another topic. Books! Below you can find a list of remarkable books, that I’d read during the last years. Maybe you find something interesting:

roadmap for 2k11

admin — Wed, 10 Aug 2011 12:05:16 +0000

A few articles (written by me) about LAMP-Performance.

Articles about Linux and hardware performance will follow in fall 2011.

My roadmap for 2011 contains the following thinks:

get inside of the MySQL core
passing the Zend Certificate Engineer Program
writing a couple of extensions for PHP
release a WordPress+Performance alternative called Speedpress
continue the development of the PHP-search engine, Theta8 and a few more

If you have any questions or suggestions, don’t hesitate to contact me. I’d like to stay in touch with ambitious people, to talk about innovative ideas and visions.

Stay tuned.

Note on Benford’s Law

admin — Tue, 22 Feb 2011 09:03:43 +0000

While dealing with Benford’s Law i noticed, that the algorithm, which used the product formula, works more than 2 times faster, then the algorithm with the summation formula. Below you can see my two implementations of Benford’s Law in C. Thanks to Prof. Dr. Klaus Neumann for any suggestions.

Params

int n := position of the numeral in the number

int d := numeral

return := p(d) at position n

Example

1337 -> 1. benford(1,1) -> 2. benford(2,3) -> benford(3,3) -> benford(4,7)

Benford’s Law with summation formula

float benford10(int n, int d){

float j = pow(10, n – 1), s = 0, i;

for(i = floor(pow(10, (n – 2))); i <= j – 1; i++)

s += log10(1 + (1 / ((i * 10) + d)));

return s;

}

Benford’s Law with product formula

float benford10(int n, int d){

float j = pow(10, n – 1) – 1, p = 1, i;

for(i = floor(pow(10, (n – 2))); i <= j; i++)

p *= (1 + (1/((10 * i) + d)));

return log10(p);

}

Hello World

Hello world – or to say it with PHP

echo “Hello World”;

?>

Stay tuned, Alex.
