Some juicy details here: http://en.wikipedia.org/wiki/Duck_and_Cover The short versions is this: in most of the area where a nuclear blast can kill you, there are simple things you can do to reduce its effects and su

How to become a regular expression wizard: 1. Write a bunch of regular expressions. 2. Fix them when they break. Anybody can do this, however junior they may be. (And yes, it does grant you a superpower.)

What WSGI is for Python, and what Rack is for Ruby, Ring is for Clojure.

The phrase "Christian right" identifies a subset of Christians; it does not imply anything more.

That's often insufficient. For MurmurHash{2,3}, for example, you can generate arbitrarily many keys that collide regardless of the random seed. Code is on the SipHash page: https://131002.net/siphash/

I'm not an expert, so take this speculation with a grain of salt, but I'd guess this is how it encrypts something in such a way as to require two people: 1. Generate a key, and use it to encrypt and sign your payload. Nothing fanc

True enough, but I'm not sure I see the relevance to the point of the article?

In doing that, you throw off the calibration and put people who aren't your friends at a relative disadvantage. Is this what you want?

Also sadly missing the Tengwar of Fëanor, though they're in the Unicode roadmap. http://www.unicode.org/roadmaps/smp/ There are not enough elves in the Unicode committee.

I was about to mention An Incremental Approach to Compiler Construction , but you've just saved me the trouble of digging up the link. It's a mere 11 pages, but it covers a lot of ground, in small, easy-to-digest pieces, and invi

They've also released code to generate an arbitrarily large number of colliding keys for MurmurHash2 and CityHash64, and one to recover the secret key of Python's randomized hash function. At some point here you're doing cryp

Not many people understand and trust the system we use now . Would futarchy actually be more confusing, or just different?

n +1 conspiracies are strictly less likely than n conspiracies, for obvious reasons. There's got to be some length of the conspiracy chain beyond which you're forced to assume that either (a) you've postulated too many c

Its main effect would be to filter out people who aren't desperate.

What the comment you're replying to is saying that glyphs may be represented by more than one code point. So sure, UTF32 has a fixed width for each code point, but it's not quite so clear how useful that is.

If you can roughly measure someone's effectiveness, then none of this matters; if you can't, then you've got bigger problems.

In one clock cycle, light would be able to travel about 780 micrometers. The real propagation speed of signals on a chip will be substantially less than the speed of light, and it gets slower at smaller feature sizes. This could be tricky.

I don't want it to happen, and it sucks. Call it a bug, or call it a feature, but remember that what you call it doesn't make it any more desirable.

Why aren't you suggesting voluntary euthenasia once the horrible dying process has begun? You've said that death isn't horrible at all, but the process of dying is, so if you truly believe those things, why wouldn't yo

It's weird how people get very philosophical and accepting about death form old age, but are horrified by murder, suicide, deadly airplane crashes, gas explosions, and so on. You get just as dead either way, but somehow death from old

That's fine, as long as you choose it rather than having it thrust upon you. Currently, we lose this choice after less than a century.

That doesn't imply anything about the most effective way to increase longevity.

Modern SMT solvers are astonishingly fast for most real-world inputs. Not bad, considering that the problem they solve is NP-complete!

Since Rob Pike and Ken Thompson are the guys who came up with UTF-8, you'd expect them to write decent Unicode encoding for Go. It would be surprising if they didn't.

Have you ever been in the news? I'd bet that most or all of the crazy hyperbole was added by Wired. The Docker guys take a much humbler tone on their web site. Please don't criticize them for over-the-top claims that they had no h
