I think that infringement protection can be handled using the following scheme: User uploads file. Mega computes the convergent encryption E(F) using the hash of the file H(F). The hash of E(F) is H(E(F)) and determines the file already exi

Actually, there are encryption schemes that allow deduplication. They leak information (that the file you have already exists), but the encrypted bits themselves are secure. The keyword is "convergent" encryption. We used something like thi

Looking forward to seeing the additional measurements. Can anyone explain why "I can’t leave it partially open or the radiator will fill with water and start spitting it out of the auto-bleed valve."? Why is partially open different from co

Colin explained it, but I wanted to apologize for the dissonance. Essentially, I'm phrasing the abstract "pick an element, then pick again" problem in terms of SHA collisions. Just for fun.

by cmurphycode 14y ago
Yeah, that was a phrasing mistake in my original post. I meant if there are ANY hashes that hash to itself (any fixed point). Thanks for noticing.

At my day job, SHA-1 is the basis for our deduplication. As such, we love talking about frames of reference for the probability of a SHA-1 collision. One of our presentations includes such facts as "the probability of dying in a vending mac

The generally accepted wisdom in the running community (backed up by a couple of studies, but what isn't these days) is that HIIT is great for making big gains in the short term, but that the gains will peak before a program with proper hig

That's just the zsh regex quirk; try quoting *.java.

I do believe the GP's message was that the tutor told him his solution took one "step", which is not equivalent to O(1), because sorted() takes O(nlgn). In other words, he was pointing out the limitations of the tutor program's analysis.

I think one huge benefit is the "instant"-esque nature of a find as you type fuzzy search in a GUI. In Bash, you can do incremental (find as you type) history search with Ctrl+R. Something analogous for grep would be fantastic. Displaying m

I understand. I worded my question poorly- what I was looking for was what they found that invalidated it as a cryptographic hash, so I could figure out whether it would fit my (non-crypto) requirements.
103.
by cmurphycode 15y ago
True. But in the case I'm evaluating, that isn't my worry. All I care about is the expected number of collisions over some extremely large number of hashes.

by cmurphycode 15y ago
The page outright says that it is not a cryptographic hash, but the Hash Quality section doesn't expound on why (except for a minor flaw on short strings for one of the functions). Does anyone know what the expected collision rate for this

I must be reading it wrong, because I see 8.4% unadjusted for high school graduates in Nov 2011. How are you calculating aggregate regardless of higher level education? I don't understand how you can just add the high school, some college,

Can anyone find a source for the unemployment rate of high school graduates? 22.9% is astoundingly high, if true. I couldn't find a source (beyond tons of articles echoing the study), and found several contrarian sources, including http://

Nice and lightweight- I like it! Seems like a really nice addition to this would be to demonstrate a quick integration with git bisect ( http://book.git-scm.com/5_finding_issues_-_git_bisect.html ). That could help you quickly identify trou

Wow. I understood the argument that the speed of the Earth's orbit dominated the Moon's, but I was having a really tough time visualizing it. The wiki article ( http://en.wikipedia.org/wiki/Orbit_of_the_Moon#Path_of_Earth... ) has a diagram

Yes-- sample size, and effect size. He's saying that the results were strong enough that given the sample size, they were statistically significant. Simple example: if I have a study of 20,000 people and I find that 51% of people prefer foo

In general, I agree, but that is the use case for the mute button.

Yup, without question. The only thing I'd warn you is that when you're doing heavy work (video encoding or lots of heavy compilation/running) or heavy play (lots of flash), the battery life will probably be just under 5. Not at all like the

Seconded. And if you're looking for the real in-depth (although slightly older) reference, check out Harold McGee's Science of Food and Cooking.

It's probably not as simple as just the fiber in fruits protecting against fructose/glucose, but it does help. (EDIT: what I mean is, don't replace fruits with a glass of metamucil and sugar :)) Soluble fiber is just that: soluble in wate
