Apple is hyping HMTL5 again, this time with a new website purporting to show open web development in action.

But Mozilla, Opera, and Google support Javascript and parts of HTML5 and CSS3 in newer versions of their browsers. And Apple's demos only work with Safari.

"It's because Apple uses browser sniffing and vendor prefixes, and in addition to that they aren't really testing a lot of HTML5 at all. Most of their demos seem to have got nothing to do with HTML5, as a matter of fact."

Its video demos won't work in Opera or Firefox because its two rivals refuse to use H.264, preferring open and royalty-free coding instead. Apple, along with Microsoft and others, is part of the patent pool that licenses H.264 to the rest of the world.

Namely, they aren't sure whether this will be a permanent block or temporary. But it appears to be linked to the 21st anniversary of the Tiananmen Square massacre, the 1989 incident in which the Chinese military attacked and arrested thousands of pro-democracy protesters.

Last year, around the 20th anniversary of the Tiananmen Square massacre, China cracked down on sites like Flickr, Twitter, Blogger, and WordPress in an attempt to keep word from spreading about it.

The latest evidence suggests that while calorie restriction is indeed beneficial for humans, when it comes to lifespan extension, it may not be the whole story.

"There's a definite possibility that if you balance the diet correctly, a longer lifespan can be achieved without full food restriction," says Matthew Piper, a researcher into ageing at University College London.

While lifespan is reduced if calories are cut too drastically, it can be extended by cutting them moderately.

Needless to say, this lifestyle is not for everyone. Some people report struggling with hunger pangs, and the society warns on its website that side effects can include feeling cold, poor wound-healing and temporary infertility.

Over the next few minutes, this "MakerBot" will do something I can only dream of doing: it will create a spare part of itself as an insurance against future mishaps.

MakerBot is one of a range of desktop manufacturing plants being developed by researchers and hobbyists around the world. Their goal is to create a machine that is able to fix itself and, ultimately, to replicate.

In a word: Persistence. Partly the traditional, inspiring, one man against all odds type of persistence, but more the obsessive, borderline insane persistence. But whatever, this dude's building his own metro, like a CITY, so I should probably shut up.

There's an old man in Russia, digging out about one metre of soil a day, right now, for a personal subway system.

A Utah woman is suing the search engine Google, claiming its maps function gave her walking directions that led her onto a major highway, where she was struck by a car.

Others have pointed out that Rosenberg might have been best served by her own eyes after she reached a T-junction and found herself confronted with a patently unsafe walk.

Ms Browner, talking on NBC's Meet The Press, said: "More oil is leaking in the Gulf of Mexico than at any other time in our history. It means there is more oil than the Exxon Valdez (in Alaska in 1989)."

She said she hoped the latest plan would work but admitted it would be a temporary measure and that a relief well currently being drilled might turn out to be the permanent solution.

Mr Suttles earlier admitted its "top kill" operation to blast waste material and heavy mud into the ruptured well had failed.

After mistakenly saying that it did not collect Wi-Fi payload data, Google had to reverse itself, saying, 'it's now clear that we have been mistakenly collecting samples of payload data from open (i.e. non-password-protected) Wi-Fi networks.' OK, mistakes happen. But, as Seinfeld might ask, then what's the deal with the pending Google patent that describes capturing wireless data packets by operating a device - which 'may be placed in a vehicle' - in a 'sniffer' or 'monitor' mode and analyzing them on a server?

Do you have a PIN code on your iPhone? Well, while that might protect you from someone making a call or fiddling with your apps, it doesn't prevent access to your data... as long as the person doing the snooping around is using Ubuntu "Lucid Lynx" 10.04.

This data protection flaw exposes music, photos, videos, podcasts, voice recordings, Google safe browsing database, game contents... by in my opinion the quickest compromising read/write access discovered so far, without leaving any track record by the attacker.

As the iPad goes on sale in the UK (and eight other countries), I've had my own "magical and revolutionary" Apple tablet for exactly 56 days. And I'm using it less and less each day.

As a fanboi, I'd like to say that the jury is still out, but I'm afraid that the most important evidence - that I'm less frequently using the li'l guy for either business or pleasure - is in.

The iPad's instant-on capability makes it more of an impulse-satisfier than a laptop could ever be.

The iPad's battery life is truly impressive, although charging it is a bit of a pain.
