Simple but yet powerful Memory Leakage Detection System GALD

By ⋅ July 18, 2006 ⋅ 5 comments

I have just released a simple tool, called GALD, which will make our life as developers easier since it allows you to detect the line where the memory problem is. The good thing is you don’t need to replace the standard malloc(), calloc(), realloc() or free() functions since a macro subsystem will address link these [...]

By ⋅ July 9, 2006 ⋅ Post a comment

1. Thou shalt not trust user inputs. 2. Thou shalt not trust other applications usage of your APIs. 3. Thou shalt not trust any files, network incoming data yourapp may process. 4. Thou shalt not overstimate the size of the destinations buffers. 5. Thou shalt close all the strings (with the NULL character). 6. Thou [...]

JSR-184 (J2ME3D)

By ⋅ March 21, 2006 ⋅ Post a comment

Some useful links to explore the world of 3D inside J2ME. It looks to be pretty good since it does not overload the hardware too much (you do not get hardware acceleration obviously) and still you get pretty good results in handled hardware. I will post more on this. Getting started with mobile 3D API [...]

SSE & Scalar to SIMD

This post will be growing up in few days: Vector normalization done fast SSE @ ars tecnica The point looks to be in doing as much operations as possible shuffling the four components you have loaded in xmmN registers:

Multi-core Processors and untrustworthy papers

By ⋅ March 4, 2006 ⋅ Post a comment

I was reading a paper about Multi-core (several processors in the same package) vs single packed processors and I rembered why I didn’t enjoyed very much IT papers. They tried to proof a multi-core architecure perform better than its older brother. They assume that a second processor in other package perform 80% and one in [...]
