No site da apple ele tem os requisitos para usares o monitor no seu verdadeiro potencial...Podes ver o Macbook Pro, Mac Pro, enfim as linha mais pro da apple, com gráficas dedicadas...

Tavam a falar de monitores e cinema displays?.... Tomem lá disto! :bigsmile:(é patentes a toda hora, não devem ter tempo para outra coisa! LOL :noworry:

Apple patents 3D projection technology


In an unusual turn, Apple has patented a technology for simulated 3D projection, filings from the US Patent and Trademark Office show. Originally submitted in September of 2006, the patent revolves around a screen with an "angularly-responsive" reflective surface, working in tandem with a projector and a secondary device, described as a "3D imager." This component is key, as it is used to gauge the position of observers relative to the screen. As a person shifts their perspective, the system reacts, presenting separate images for left and right eyes.
Such a technique ultimately fools the brain in order to "mimic a hologram," according to the patent. Crucially, viewers need no special glasses or helmets. Images can parallax along multiple axes, and there is no need to remain in a single spot for the full effect.

What Apple would do with the technology is unclear; while Apple does produce branded displays, it has never sold a projector. Likewise, the proposed system would likely be elaborate and expensive, requiring three different elements that must be positioned neatly around a room.

Para ja contento-me com o 15.4... Para alem de resolução, a tecnologia OLED, faz as cores terem outro intensidade, para não falar do preto, verdadeiro dark black. Como se não basta-se gasta menos energia e tem sempre o mesmo aspecto, olhe para ele de frente ou de outro lado qualquer...

Já conhecia a noticia...
Nada é perfeito, enquanto houverem este tipo de noticiais, mais seguros ficam os sistemas, até porque actualizações de segurança não tem faltado... Quando ao resto já se sabe que um sistema baseado em Unix BSD vai ser sempre mais seguro que um windows e não é uma vulnerabilidade do safari que vai provar o contrario

Miguel, so vem deitar por terra o mito q os Mac sao super seguros, etc etc etc.
a medida q a base instalada aumenta, vai aumentar tambem o conhecimento de falhas, pontos vulneraveis, erros and so on.

The supposed hack was on the second day of the challenge which isn't mentioned by MacNN. Not a single attendee entered the contest on day one, when all vulnerabilities had to reside in the machine's operating system, drivers or network stack. On day two, the attack surface was expanded to include browsers, mail applications and other common applications.
He exploited a bug in Safari. Nothing says this guy didn't find the exploit in Safari before going. Does this exploit affect firefox also?

ah, not 2 minutes

What the article does not point out is that on the first 24-hours of the contest, the contestants were suppose to do an attack on the Mac remotely via the network alone.

No one could hack the Mac remotely via the network alone.

The second day, they relaxed the rules and allowed the contestants physical access to the Mac so that they could install an automated user to receive emails or use a browser to go to a malicious website set up by the contestant.

Duh.

It took more than 24-hours to hack the Mac. It takes days to program an automated user or develop and program a malicious website. They had to do the work even before the contest.

And it took physical access to the computer to hack it. They could not hack it over the network at all!

Thus the contest is a crock.

I doubt any user will allow a crook or stranger physical access to their personal computer. Once a person has physical access to a computer then any computer can be hacked. Through the firewire ports, any Windows computer is instantly compromised, for example.

e isso veio de um site dedicado a que? ah sim...mac..pois

Eu pra mim o MAC e Linux não são mais seguros nem menos vulneraveis, apenas acho que o windows é mais fustigado por ter muitos mais utilizadores, e consequentemente mais gente contra.
