3 Switches riddle

This is a riddle that I will never forget about…

“There are three light bulbs in a room, and three light switches outside the room. You are outside, and want to match up which switch goes with which light bulb. You can only travel into the room once, and cannot come back in again. You can do anything you want upon entering the room. How can you set the situation so that you will know which switch goes with which light bulb?”

The answer? Think about it! (or google it )

VideoTrace: Rapid interactive scene modelling from video

I’ve found an interesting project of the Australian Centre for Visual Technologies. It allows to create 3D models from a video.

Select the points in several frames to catch all perspectives, then a 3D model is made using the video images as textures.

You can see the video and read more about this project in this website.

C-Jump - Never to soon to start programming

I was really amazed when I found this game. Sincerely I have never imagined that there was a board game intended to bring children attention to the programming world. Just forget about Monopoly! Being a geek is fun!

In this game rules there are references to If Else and Switch statements and event variables increment. The board is a big block diagram where you move and interpret each instruction in which you fall. Pretty geek, hum?

It is a nice suggestion now that we are so close to Christmas

Eu no Live Search e no Google

Andei a pesquisar pelo meu nome no Live Search e no Google para ver se este novo domínio já aparecia num ranking decente.

Realmente já aparece na 1ª página do Google e do Live. No entanto queria chamar à atenção para outro “pormenor” com o qual me deparei. O meu blog do Blogger (AKA do Google) nem sequer aparece até á página 10 de resultados do Live Search. Artigos do meu blog que no google aparecem facilmente nos resultados de uma pesquisa mais genérica, no Live Search nem sequer aparecem.

Das duas uma, ou o google benificia imenso os conteúdos “da casa” ou o Live Search irradica os resultados referentes ao Blogger…

A nice and useless geek trick

Go into any website with images on it. (Like Flickr).

In the address bar type

javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI= document.images; DIL=DI.length; function A(){for(i=0; i<DIL; i++){DIS=DI[ i ].style; DIS.position=’absolute’; DIS.left=Math.sin(R*x1+i*x2+x3)*x4+x5; DIS.top=Math.cos(R*y1+i*y2+y3)*y4+y5}R++}setInterval(’A()’,5 ); void(0)

Then you get something like this.

Completly uselessI know… But i thought it was funny
