Submission + - Announcing the first SHA1 collision (

matafagafo writes: Google Security Blog just published

Cryptographic hash functions like SHA-1 are a cryptographer’s swiss army knife. You’ll find that hashes play a role in browser security, managing code repositories, or even just detecting duplicate files in storage. Hash functions compress large amounts of data into a small message digest. As a cryptographic requirement for wide-spread use, finding two messages that lead to the same digest should be computationally infeasible. Over time however, this requirement can fail due to attacks on the mathematical underpinnings of hash functions or to increases in computational power. Today, 10 years after of SHA-1 was first introduced, we are announcing the first practical technique for generating a collision.

Comment Interesting to mull over effect of shapes. (Score 2) 90

I was also mulling this over in relation to the movie World War Z where (spoiler) zombies piled up against a wall until they got over the top...

Even against an angled wall that would work after a while I imagine, as you packed in enough tipped over zombies. But against curved and angled wall it seems like it would take much longer to work as most of the mindlessly piling on zombies would slide to the sides, or possibly even the force of new incoming zombies pushing the zombies up against the surface of the curve to either side. It would be really interesting to simulate.

I think you are right hat against Walking Dead zombies, it would tip them over and they wouldn't be able to exert any significant force on the wall. Indeed a pack of them would be helping to hold up a wall canted outward!

A new innovation for Zombie movies could be some kind of "stiction" zombie, that could attach to a surface, chemically bond, then pull instead of mindlessly ramming...

Comment All you Apple Haters can bite my shiny metal SD (Score 1) 46

Sony has also introduced a new memory card reader, the MRW-S1, due for release in April. It features an in-built SuperSpeed USB port for cable-free PC connection, so that your files can be copied faster than by using the slower SD slot on a PC

I seem to recall an awful lot of Apple Haters whining about a certain new MacBook Pro that had dropped the built in SD reader...

You just keep on using your slow vestigial reader while us MacBook Pro owners stay at the forefront of technological advance.

Comment Apple once again late with a product (Score 3, Insightful) 90

I have said it before: the ring is a massive Reality Distortion Field Generator.

As per usual Apple is late to market with an inferior product.

Apple Haters have been carrying around a small portable reality distortion generators with them for years that allows them to see Apple's growth as retraction. They appear to have a boundless power source and are so strong no reality is able to break through no matter how discordant the internal view becomes!

Comment Think on your actions and what they lead to (Score 3, Informative) 121

I haven't even spent a dime on Pokemon Go and I play it daily.

So since you are so fond of it, would you like to see MORE of it, or LESS?

Would you like to see it improved at all?

By not spending any money, you are in effect saying "This game I really love, I sure hope they never improve it or keep up with system updates! Maybe someday it will be so behind I'll have to stop playing!".

I also really liked PokemonGo. I was fine not paying for anything myself, I never felt the need to - but I still spent $5 or so on Pokecoins just to support the company, to say "Thanks for the enjoyment I've had playing this game".

My Philosophy is simple, if I see something I really like I try to support the creators by any means possible.

Comment Not silly at all, consider context (Score 1) 121

You aren't taking into consideration that Android OS covers the most cheap bare bones phones/tables/etc to the comparable galaxy/etc devices.

That is irrelevant - they are not the Android devices Slashdot readers would be using. What I am saying is a sampling of high-end Android users here shows DELIGHT in not paying for apps. And that plainly shows in continued low purchase rates for apps on Android compared to iOS.

Comment App subscriptions easier to cancel (Score 1) 121

You probably bought it through the web so they do not get any of that. But users can purchase a lot of sports app subscriptions through apps, which Apple does get part of.

I bought my HBO subscription through the app, since that way HBO never gets any payment info form me, and I have to deal with zero humans or terrible billing interfaces to cancel - I just stop the app subscription.

Comment Witness the Wastelandroid (Score 4, Insightful) 121

I thought $40 on average seemed about right, given the explosion of in-app purchases for not just games, but apps like HBO... (don't forget the AppleTV is an IOS device). I myself probably spent more like $200 last year on iOS app store purchase (which include subscription to HBO for a few months).

However look at the other responses here, proclaiming how proud they are to have spent $0! Is there any wonder why Android continues to be a second tier when it comes to app development? It makes you question if there is any use at all in ever developing an app for Android if what you get out of it is to be anything but breadth of exposure.

I myself am proud to spend money on apps and help support a sustainable app ecosystem where I will see real improvements to apps because people are willing to spend money...
