Permutation and Combination…again.

admin — Tue, 31 Jan 2012 18:27:14 +0000

These here are updated versions to my previous attempts at listing permutations and combinations, and these are a lot shorter than those and easier to understand. Even though it is in C++, converting to pure C is not a huge endevour either. Combinations #include <iostream> #include <string> #include <cstdio> #define MAX 100 using namespace std; ...

admin — Sat, 28 Jan 2012 16:49:36 +0000

After a great deal of searching through Android documentation, I’ve made a simple shell script that’ll send SMS! To send, run this script with argument 1 as the phone number(in CCIIXXXXXXX format C is for country code and I is for company code) and argument 2 as the message. Use “” if you have spaces ...

Spectrum

admin — Sun, 08 Jan 2012 12:12:53 +0000

This is a sound spectrum using ALSA & OpenGL, it is not a *proper* spectrum because it does not have any FFT support it just shows data only ordered by time. Download the code and ‘make’ to compile. Following packages are needed, freeglut3, libasound-dev

Dancing cubes

admin — Sun, 01 Jan 2012 16:30:13 +0000

This is true ALSA multi-threaded capturing! This my first, ALSA and POSIX thread application. Happy that it works as intended(well I hope the cubes jumped much higher but hey..they jump!). Drawing is done on one thread and the capturing is done on another. Make sure you set the recording source for ALSA to your system ...

admin — Sat, 31 Dec 2011 13:18:44 +0000

Enter “Balls from heaven”! This is an improvement to the bouncing ball application I posted before, I left it as the way I found the code snippets from multiple sample projects and tutorials, now that I’ve got the hang of it more stuff can be done. The source includes links to some sites that I’ve ...

admin — Thu, 29 Dec 2011 20:30:06 +0000

Download Source You need to install the following(Ubuntu) sudo apt-get install freeglut3-dev sudo apt-get install libode-dev For other OSs ...

All Oneiric users are having an ibus bug that does not let them to use any plug-in for ibus to work properly(unprocessed keys such as spaces get added to the text before the converted text). Seems it was introduced with Unity, but it is not just Unity. I am not using Unity(Kubuntu+gnome-shell), but I was ...

The answer to problem X, in IEEEXtreme 5.0 and I didn’t even read it properly in the competition trying to do other problems, and without a fresh mind to think it through this one slipped out too. Anyways, did it now and C++ really boosts your development time. I don’t care what others say, I’ve ...

Xtreme cable ways

admin — Sun, 18 Dec 2011 12:00:03 +0000

This answer is for the question C in IEEEXtreme 5.0, is based partially on my answer at the actual competition(still don’t feel like giving up on this one, it kept on getting errors back then). It features a timer too, I need you to run it(by compiling the original version by me, ofcause) and get it ...
