Besides, symmetric schemes tend to perform better. Hence the idea of using a public-key scheme like DH for key exchange and then switch to symmetric crypto like AES. Always avoiding public-key isn't really possible unless you have some

> factoring sufficiently large prime numbers You probably didn't mean it that way but I feel like fixing that. Prime numbers have no factors except for 1 and themselves. That's the definition of a prime number. What you're

bcrypt is not bad and you're definitely better off with that than with MD5, but scrypt performs better for these sort of things. There was an article on HN a week or so ago about this.

I tried that with QEMU once. It sort of works but I didn't really go too far into it. I did it more to see whether it could be done or not. That's actually the only time I've used OS X by the way, so I might have missed some

Isn't there some sort of OwnCloud client for Android? You could use that as your storage solution, hosted on your own machine which should be completely under your control.

I always put it the other way. The problem with other text editors is that they are not vim.

Almost certainly the latter. Which reminds me to think about ways to ensure the persistence of sensitive data that is important to the general public. Either way, I'm pretty sure there's a backup somewhere.

Good to know that. I was trying that code in GHCi, which explains a few things now.

Haskell foldl' (+) 0 [1..1000000000] You could use sum, but that will eat up a lot of RAM because of the laziness. EDIT: For the fun of it, I decided to do the same in a slightly more esoteric language, so here's a Pr

I don't quite believe that the NSA can reliably perform a ciphertext-only attack on RSA or even AES. As far as we know, integer factorization is still hard, so RSA is still secure, given large enough keys. There's Shors Algorithm

Yes, but not in a technical sense. People think encryption is hard. They believe that they have to jump huge hurdles and will be confronted with an incredible learning curve in order to protect their privacy via encryption. The fact of the

At least using PGP or GPG for your emails isn't much effort. These tools are very easy to integrate into all of the common mail clients and some web services. The only "hard" part is to get your communication partners to use

More Encryption is not the final solution to the problem. I fully agree here. However, encryption should be the default for all communication. It provides a certain degree of privacy after all. Yes, there are weaknesses in some of the too

More or less, yes. What he is saying is that there is a constant hidden in the big O. Say, we have two algorithms A and B with a runtime that can be bounded by the functions a(n) = 1000n^2 and b(n) = 0.001n^3 respectively. Hence a ∈ O(n^2)

Doesn't bash already do something vaguely similar though? I noticed it can complete flags and options now. zsh has been capable of this for a long time too. It doesn't convert between long and short options or sort arguments but i

Then again, Apple was (and still is) huge on the mobile sector. As far as surveillance goes, I'd expect mobiles to be of high priority.

A take on being international perhaps? As far as I know the US is the only country that uses M/D/Y format. PRISM does not only concern US citizens.

What sorts of websites are we talking about here? I understand that some websites have to transfer a couple of megabytes to be displayed (though most of that is media content anyway) but how does that end up occupying 100MB of RAM? That&#x2

It is not transported over HTTP, although it does make use of HTTP at the Application Layer. It is transported over TCP, which is a Transport Layer protocol. Yes, I'm being pedantic and annyoing.

Weren't there cases of the government forcing people to give them their passphrase in the US already? Somehow I seem to remember something like this very vaguely.

I agree with you disagreeing. The article really blurs the line between mere code formatting, which can be completely automated to adhere to some guidelines, coding paradigms and software design/architecture. I'd argue that, for a product t

As someone who made best progress following the ideas described in Starting Strength after trying numerous approaches that didn't really work, I'd say you can safely assume N=2 now. Really, this book teaches a very "old-school" approach to

I never really understood why C gets such a bad rep for readability. It's a very compact language, just having a couple of keywords and a few very fundamental concepts. There's no "guessing" what a line does, no "obfuscation by design", etc

In fact, I'd like it more if it was a compiled executable. A couple of weeks back I did something vaguely similar out of boredom on a sunday afternoon in C. It's quite simple, technologically speaking, but a lot of fun to play around with.
