Cheap GPUs render strong passwords useless

[notyoueither]

I truly hate this practice. It's like the password recovery options on most sites that only give you a handful of generic questions that could be easily guessed based on publicly known data. I stopped using a bank not long ago because they did this and the hardest question they could come up with was "what was your high school mascot?".

Uhmmm, you use a bull**** answer that nobody could ever guess?

'What was your favourite pet?'

Answer: Gwar rules the universe.

Wonderful. An excellent idea that Joe User will have absolutely no problem with, ever. Why should I have to jump through hoops to make their system secure?

It was quite clear what I meant to anyone with social intelligence.

True.

[Asher]

That's one type of exponential function. What you meant to say is that the growth wasn't exponential at all, it was discontinuous.

What I said was obvious to people with social intelligence (i.e., those who can infer meaning from context). I don't always have time at work to be verbose and mathematically precise when it's not really required. Even Kuci could figure out what I meant by it, he was just being pedantic.

Typical Poly though isn't it. An interesting debate ruined as it turns into an intensive debate of some trivial word in the middle of a sentence somewhere.

The use of GPU power for non GPU tasks in general is a fascinating topic.

I've got a project at work where we use OpenCL to do all kinds of wicked things. We've got an optical touch system (4+ cameras on a very large surface to implement multi-touch with great precision). With a dual-core CPU, we could accomplish 1 touch with accuracy. With an ASIC, we could do 2 touches with accuracy. We've ported the code to OpenCL and run it on Radeon 5850s and we're up to 8 touches, with even more accuracy. The amount of computations they can do is breathtaking, really. It lets us get away from taking shortcuts. It not only recognizes touches, but the surface area covered by the touch and can also infer object types from it (eraser, pen, finger, balls [lots of teachers like students to throw squishy balls or tennis balls at the screen to select things -- don't ask], etc).

We are also using it to implement physics for our science suite. It's a newer version of this:


With the latest OpenCL & GPU architectures, you can run multiple OpenCL kernels at once with multitasking as well. No more context switching penalties.

The technology advancement in GPU accelerated computing is a game-changer for many, many fields.

Porn and Games, driving the internet and computing.

[Asher]

So true.

Thanks for the link, I think my fiancee could find this useful in her school, seems pretty affordable too. How do you rate it?

Password management in large corporations is already retarded as it is. When this is disseminated through those workshops security consultants usually attend, it will finally become unbearable and ridiculous. Our Austrian overlords have already insisted ALL password should be changed on the monthly basis and should contain a capital letter, a digit and a special symbol. NO ONE will come up with a unique password every month, especially when you have to connect to five Oracle DBs that of course do not use AD. I am not going to invent eight passwords every month (1 for AD, 1 for the new system, 1 for the old system and 5 DBs). I use 1qaz!QAZ technique for my AD password and because neither Oracle nor both of our systems allow punctuation, use a simple incremental scheme for all of them. And yes, I keep these passwords in a text file in My Documents.

Are you referring to that software (Algodoo, which we didn't write but we're partners with them), or the boards themselves?

The software, she already has an interactive whiteboard and until it breaks no one would even think of a replacement.

Which company makes her board?

I'm not sure how much the software costs. We're going to be bundling it with an upcoming version of our software (which I think she uses, if she uses our company's board).

Fixed.
