Comment Re:Are two hashes better than one? (Score 1) 143

Finding collisions in MD5 and SHA-1 simultaneously is only marginally harder. Using Joux's multicollisions, you can finding a collision in both by running the SHA-1 attack 64 times: this defines 2^64 messages colliding for SHA-1, and you can locate a collision by evaluating all those hashes (wich costs less than finding the SHA-1 collisions with the current attack).

Would Linus Torvalds Please Collect His Bitcoin Tips? 231

jfruh writes "Tip4Commit is a new service that allows anyone to link a tip for a developer to GitHub commits for open source projects. The tips are denominated in Bitcoin — and it appears that some developers aren't interested, with almost 40% of the total value tipped going uncollected. One dev who hasn't collected his $136 in tips is Linux inventor Linus Torvalds. It's not clear if the devs who aren't collecting their tips are opposed to the concept of tipping on open source projects or just don't want to deal with Bitcoin."

Comment Security concerns (Score 1) 327

This all networked car thing is a disaster waiting to happen. The basic idea that your car will make important decisions based on information sent by random strangers can only lead to a catastrophic failure.

What happens when someone sends a signal saying that there is a car stopped just in front of you in the highway? Your own car will stop suddenly, and you might get hurt in the process!

Of course, there will be some kind of authentication of the messages, but everycar has to be trusted by default for the system to be usefull. And we all know how easy it will be to extract the signing key from a given car and to spoof messages...

You and the other poster seem to be forgetting ONE thing, which is nobody gives a shit how low the power draw is if it can't do what they want and what people WANT is MOAR, MOAR HD, MOAR games with MOAR graphics, MOAR MOAR MOAR.

As far as I'm concerned, I don't give a shit about how much I can do with my phone if it draws too much power. If the battery can not last at least ten hours on idle, a phone is just useless.

Comment Re:Forget computers, they're extraditing the perps (Score 1) 105

So after they do their time in the US they're going to be judged in each country where a machine was infected? That's fucking scary!

And if I have a website explaining people how to use TOR, and it turns out that explaining this is illegal in China or in North Korea, will I be extradited to those countries?

Comment Linux Falsh support has allways been shitty (Score 1) 404

Flash support for Linux has always been pretty bad. Most people switched to a 64-bit distro years ago, but Adobe has only supported flash on 64-bits Linux for 6 months... Sure there was a beta version available some time before, but security holes where not fixed in a very timely manner for the beta, so it was mostly useless. In fact things are just going back to normal.

Can NASA Warm Cold Fusion? 556

TomOfAmalfi writes "Andrea Rossi says he can provide domestic energy sources (about 10 kW) based on his E-Cat system (a Low Energy Nuclear Reaction or Cold Fusion energy source) for between 100 and 150 US$/kW and begin shipping this year. Many people are skeptical about Rossi's claims because he has not explained how his 'reactors' work (apparently the reactors contain ingenious security devices to prevent reverse engineering), there is no theoretical basis to support his process, and no one has supplied independent measurements to support the specs on his black boxes. However, buried at the bottom of a NASA web page there is a comment about progress in 'cold fusion' research and a link to the slides used in a September 2011 presentation (PDF) which talks about LENR research. NASA has also released a video describing the great benefits we will get from NASA LENR research. Could Rossi be on to something?"

Moreover, the virus does not seem like a very good weapon to me as it is simply impossible to control or contain its propagation once released. This is the reason why modern armies do not use gas for instance.

The threat we are currently worried about is not a modern army, it's a bunch of crazy terrorists. They don't need to control the propagation.

Note: I'm not saying that we should be worried about terrorists plots, I'm just saying that, as a society, we are.
