I thought that too but late last year one of these Bradley Manning articles seemed to suggest that data might be able to persist after a simple zero-fill, so I thought I'd use my prng script before zero-filling, because it's as fa

This might have been more fun but there exists the possibility that someone might ransack the laptop for components, and I actually like the idea that they might be successful.

Right, it's more that those were the LiveCDs which I had on hand to try and I didn't want to research alternatives. What I really should have done at the time is to ask around on Freenode or some other IRC network; someone could p

At best that's a symptom. Cookies are for session management; the central problem with cookies is that people feel that servers will treat certain sessions as ephemeral, but instead those servers track these people for a long-term cr

I had a nightmarish scenario a few months back where I was just trying to wipe an old hard disk on an old laptop that still barely worked, so that I could ship it off to an electronics recycling place. It was I think 512MB of RAM but might

Probably the best KDF you'll get right now is scrypt[1]. NaCl did not see common adoption because until a relatively recent distribution called Sodium[2], it was not portable. And I mean really, not portable. Like, just to give an ex

Fair enough, it's a little simpler but of the same kind; it's the same "yeah I have this space which I'm not using, so what?"

Ah, yes! Sorry, I'd forgotten that those existed as well. I never really saw a deep potential for those -- the problem being that you cannot open the outer drive for writing without providing the password which enables the inner driv

It might, but to be perfectly honest most people don't keep partitions of random-looking data, or large files containing what looks like it. Your plausible deniability would be of the form, "I was getting ready to make a hidden vo

Those are only little WTFs. The fact that object-equality is being tested for, for example, is not a WTF on its own; it's a valid concern in any non-functional language (answering the important question, "will editing X affect Y?&

You could potentially affiliate with social networks in such a way as to leave a clear fingerprint; that is, you could be, both in your 'anonymous' and 'real' life, the only person who connects 20 different social groups

Aside from being insecure it is also not robust (fragile?). So, suppose Paul can lie to Alice and Bob, and they cannot lie to him. He can probably interview them separately, too. We can ask how the system will break, either inadvertentl

There's actually a really sneaky moment in here which is not totally revealed. Feynman says that he first works out 12, then 12.002, then the man with the abacus says "12.01!". He asks for more digits. What is sneaky here is

In my usage of Tor it seemed like the router would choose a small subset of the network to be my set of entrance nodes[1] and the exit nodes chosen were also a small subset of the network[2]. Just clicking "new identity" on Vidali

That hassle can in principle be totally mitigated. When you buy an OV-Chipkaart from a service desk (like an NS desk at a train station), they will not only charge you the 15€ (or whatever) fee, but they will also ask you how much you want

You're right, I should have just stuck with Jordan blocks, and I'll try to remember to do that next time I explain this to someone.

I find that at a high Bachelor's or low Master's level in physics I always have to re-explain determinants. People learn the idea and they take away "it's really complicated and has something to do with whether the matrix is invertible." An

What's very common in the Netherlands is simply to have a medium-sized plastic bowl which can take up a little over half your sink. (It can be square and bucket-ish but it should not be inconveniently large.) The idea is that you let a thin

The story of the fastest enlightenment in Zen has to do with washing: A monk came to Joshu, asking, "Master, I just entered the monastery: may I have my first lesson?" Joshu asked, "Have you eaten your rice?" He replie

If you ignore the fact that the vertical and horizontal aren't scaled the same (which can be part of the last step in the rendering code) then you can define a hexagon as six lines in [x y] space, as defined by their endpoints: [[0 0]

That was the very first thing I said; the production rate is ramping down exponentially. I agree that if you're a consumer, Moore's law has less to do with BitCoin, but the whole point of the comment was stop looking from a consumer's pers

That was in some sense intentional -- I prefer exp(i μ k) exp(-k² σ² / (2 n)) for the clarity of the expression in Fourier space. That issue is not avoided -- it becomes ln(cosh(k)), which still only has a finite radius of convergence due t

Maybe. But the proof also gives a lot of cute ideas for how to go further with this sort of demo. Since adding random variables amounts to doing convolutions with their distribution functions, if you had a Fourier transform package in JS yo

People are down-voting this (presumably for containing the words "central authority") but it's actually pretty realistic. What we need is a log-linear graph of a few things. The BitCoin production rate is ramping down exponentially, and eve

I've already graduated at this point; I had to write a thesis, but when you've got two interesting projects going on at once, it's hard to say which is the "procrastination." My point was more that the programming projects "have not moved f

I liked this but as other commenters have pointed out it's purely binomial at this stage. The great thing about the central limit theorem is that it is more general than just the limiting Binomial case. So, there's this thing called the
