Google executive Dan Fredinburg was among 18 people killed on Mount Everest after a 7.8 magnitude earthquake ravaged Nepal on Saturday.

A woman who identified herself as Fredinburg's younger sister, Megan, said on his Instagram page that he had a major head injury after the avalanche triggered by the quake. He didn't survive.

The catastrophic earthquake Saturday killed more than 1,300 people and leveled ancient buildings in the Nepali capital of Kathmandu. The quake was so strong that it also killed people in nearby India, Bangladesh, and Tibet.

Fredinburg â" who was head of privacy for Google X â" survived last year's deadly avalanche on Mount Everest, according to media reports and his Instagram account.

PDF is an output format all the structure that went into the document has been removed pretty much.

While you can get to the elements of a pdf document its very difficult to reformat them. for example say there is text in 2 columns selecting them you get a single column with the left side from column 1 and the right side from column 2 scrambling the sentences to make nonsense. The structure has been left in the word processing document. which is where you must return in order to use a smaller page size for example.

There are a number of formats where you can classify the file as output for example jpeg loses the raw data even an mp3 or audio file which may have had 24 tracks you can't just remove the drums...

The physical world is full of non editable things.
So no you don't need a pdf editor you need the word processor document which the pdf was generated from.

The headline was bad, as it doesn't include the qualification.

It is a limited qualified version of free.
Free to learn on, is about it.
If you get good at it and show some talent you might be suitable for hiring by pixar.
I don't think there is anything of interest for programmers there either.

It is kinda cool that they have released this cross platform, but you can see how its a little self serving for pixar. Clearly they seem to want a cut of any profits that might be made from a small independent film maker using this software.

This release basically targets potential recruits that should need less training if pixar finds them talented.
maybe i'm too cynical

Comment: change password before going to NewZealand (Score 1) 200

People are stupid on average and would be daft enough to leave incriminating files on laptops and smart phones that's why customs needs an over-reaching power like this.

The problem is really is revealing a password that you use elsewhere. So change it before you go make it 1234 or password or some other trivial thing. Maybe put a fresh copy of windows on before you travel, or would that be suspicious in itself. Customs can give you a hard time already even your butt isn't secure.

New Zealand wouldn't be the first country to make failing to hand over encryption keys illegal, just make sure your laptop is clean and it isn't a problem. It's not like you can't download a file once you are past customs.

I think its fair to say that it takes a user to install it first, linux has pretty much always had trustworthy repositories, Google not so much.

I love some of the things you can add to chrome but there seems to be little to no security checking of what an app or extension does. That does worry me.

Actually it does make sense small cracks do concentrate stresses at the head of the V which break through the crystal structure a layer at a time.

As a simple demo get a piece of paper and pull on it, you will find it pretty hard to tear it , now just nick the edge of the paper and try again, you should find it yields quite easily.

The tensile strength of steel would be a lot higher if it wasn't full of imperfections. incidentally there are two crystal structures you get with steel face centered cubic and body centered cubic

now the interesting thing about this is that when you cool down steel rapidly you get one form and slowly you get the other form so if your quenching something more than a foot thick you get both types of crystals since heat just isn't removed fast enough from the centre. the larger crystal structure is in the centre and the smaller crystal structure is on the outside. This means the inside is trying to be bigger than the outside. so the outer surfaces are massively stressed. like a bomb stressed seriously. You can't cut through steel stressed like this with a saw as the cutting would unbalance the stresses and it would blow apart, so you have to do something called plunge grinding which is done in a massive lathe with a grinding wheel taking it down equally on all sides.

This is what happens when you produce a roll for a cold rolling mill the outside is very hard with a softer core. Usually the forces are lower than the uts of the steel but sometimes it isn't and you get catastrophic failures. generally this happens in the quenching tank where its safe you normally hear a few bangs as lumps of steel spawl off from the outside followed by a boom as the roll breaks apart and goes crashing down to the bottom of the tank.

Rarely they fail after the heat treatment, joe the hardness tester where i used to work was nearly killed by one. he'd hardness tested it around 12pm (the hardness was abnormally high around 890 vickers) an hour later it blew apart a ton and a half of journal end was launched across the factory floor missing his legs by inches. he was off work for a week after with the shock. We also had a used roll blow up in a storage warehouse one weekend and it took a wall out, this had been in service and had been worn down to below a serviceable size. Even after all that time it was still stressed ...

back on topic , it seems reasonable that by removing the sites for cracks to occur the uts of the steel will be much higher, normally the way round the problem is to make the thing bigger that way the forces applied will not break the cross section of course that makes it heavier and harder to work with which is why its a specialized area like drilling where this has been applied, with the plating thicknesses used the cost will be way higher than for the regular steel pipes, i'd expect probably more than 10x the cost but the rig would be able to drill deeper and that's what matters, and the return on that makes the drilling costs look like peanuts.
