Studying the basics of cryptography using XOR I've decided to to design some XOR graphical representation, as several that we can find in the Web (http://en.wikipedia.org/wiki/Xor). The result can be seen bellow. It is very interesting to see the symmetry of result.
Através da criação do "Identity Protection Technology", IPT, a Intel passa a oferecer em seus processadores i3, i5 e i7 (2a. geração) e posteriormente nos Ultrabooks uma série de recursos de segurança. Tais recursos estão embarcados em uma área do processador chamada de Management Engine (ME). Essa área pode ser acessível através do bus PCI por meio de um Firmware embarcado na BIOS e um driver. Dessa forma diversos algoritimos de gerenciamento de senhas, proteção de identidade e autenticação de transações, que normalmente são feitos via software dependentes do sistema operacional, podem agora ser transferidos para para execução interna no ME dentro do processador e assim garantir a inviolabilidade desses algoritmos. Além disso somente algoritmos assinados por certificados reconhecidos pela Intel poderão rodar nessa área do processador.
Para que os usuários comuns possam se beneficiar dessa tecnologia em acesso a bancos, lojas eletrônicas, redes sociais, etc, essas empressas precisarão que seus sistemas de segurança e autenticação sejam atualizados para funcionar nesse novo padrão. Para isso a Intel estabeleceu parceria com a InfoSERVER S/A para o desenvolvimento de soluções que permitam a integração do mercado.

JAmtConnector is an OpenSource application (written in Java), release under Eclipse Public License, that can connect an collect data from vPro machines over network. It uses web-services for communication and works with machines that has AMT version >= 3.0. The software was built based on Intel® WS-Management Java Client Library.
This software also can be useful for who want to learn how to implement AMT resources through Java and Web-Services.
This application, works in Command-Line Interface (CLI) and also in desktop. See the example bellow:
A Subversion client, implemented as a windows shell extension.
TortoiseSVN is a really easy to use Revision control / version control / source control software for Windows.
Since it's not an integration for a specific IDE you can use it with whatever development tools you like.
TortoiseSVN is free to use. You don't need to get a loan or pay a full years salary to use it.
Today I was driving in a road near Sao Paulo, when I've decided to stop to get some snack. When I was going out to my car, I saw in the parking lot the car from Google Street View. I decided to take some pictures using my tablet, but when I came very near the car, trying to take some pictures through the glass windows, the driver (from Google), already upset, said me:
- Hey guy, take pictures from outside is ok, but you cannot take pictures of things that are inside the car.
Then I said:
- Yes, I can!
Then he said:
- No, You can't. Now you are disrespecting me!
Then I said:
- No, I am just doing the same thing that your car does!
Last month I've wrote with my friend Juliano Marcos Martins, an Installation Tutorial of DB2 under Linux, just using terminal (Command Line Interface). But I've just had time to publish it today.
Depois de algumas conversas com meu pai, sobre suas experiências de infância derretendo chumbo, tentei me aventurar no derretimento do alumínio. Vejam os resultados iniciais.
É realmente impressionante como o fornecimento de oxigênio corretamente direcionado às brasas faz com que ocorra um salto para o ponto de fusão do alumínio.
O próximo passo agora é criar um cadinho. Os meus primeiros testes com porcelana e posteriormente com ferro envolto em areia, falharam.
Um dos momentos mais interessantes dessa experiência, foi manter o alumínio líquido por alguns segundos e com esse tempo poder manipulá-lo.
