KDE 4.0

So today is the great release of KDE 4.0. And by the way, KDE 4.0 is meant to run on almost every platform including windows.

So what I did was to download the installer for windows and play a little with it. Below is Dolphin on Windows (the screenshot could be more exciting, but I’m kinda late for work).

Guy Fawkes

V for Vendetta

Remember, remember the Fifth of November,
The Gunpowder Treason and Plot,

Why Gunpowder Treason
Should ever be forgot.

I want a Guy Fawkes mask!

So, just got home and, as usual, I was checking e-mail and RSS before hitting the bed… And then i faced this news: an open source 3D printer.

So much pain in the world today

Shelley MarshSo much pain in the world today.
Too many turds are headin’ my way.
But we can press our turds together.
Passing by turds whenever.

Don’t you know? Isn’t…

Life so full of happiness?
Feel free to mark my words.
But me and you, will my love do
in a world that’s full of turds? TURDS!
llama judgin finger-lovin’ turds. TURDS!

fglrx and AIGLX

There’s been a great progress on the fglrx ATI driver. However, it needs more development. Not only 3D OpenGL accelerated applications but also video playback (which, I guess, uses OpenGL) needs to be rendered correctly. Video playback, for example, doesn’t play in window mode. While in fullscreen, it flicks a lot =/ It was under Ubuntu 7.10.

Multi-Massive Parallel Computing

And here is the first step of my Master’s thesis: studying CUDA. In shortly, CUDA (Compute Unified Device Architecture) is an GPGPU language and runtime for the new GeForce 8 Series and so on. It’s a complete new paradigm, where programs written for such devices must have a parallel nature. So it isn’t so general purpose as it claims to be ;)

However, this whole paradigm will soon give me some headaches. Just look the figure below:

CUDA Computing Paradigm

(Figure taken from Nvidia CUDA: preview)

As you can “clearly” see, host is the CPU side and device is GPU side. A kernel is a program designed to run in parallel. The execution occur on a grid, which is divided into blocks, whose are composed by threads. Blocks and threads run logically in parallel, while a set of threads, called warp, run physically in parallel.

More will come, by the time I learn things ;)

Why did they left beta?

Why Google Reader left the beta status? To me, they need to test Google Reader under many scenarios. Just see the picture below (it is worth a thousand words). To reproduce it, just press ‘r’ a lot of times.

Google Reader out of beta?
