Have you actually tried implementing something like A*? The inner loop is very tight, and putting several easily avoided dictionary lookups in there is just silly. Given how simple it is to write a solid abstraction that implements the coor

This shouldn't even be that difficult to rig together: Take a small USB key, combine with a wrist strap, and write a script to listen for USB key disconnects. As a bonus, if you want to get fancy, the encryption key itself (or a part o

You write it down because it's a business and you need some amount of documentation to run any business. The journal thing could have been avoided, but the chat logs? There are bound to be disputes when running a black market, and it&#

In fairness, it's a bit of both. The position of parents on the income scale vs. the position of children on the income scale is (too) highly correlated all across the income scale. The mechanisms for this correlations are different on

Somewhat tangentially related, the for-else-statement of Python is something that I occasionally miss in every other language that I seriously use. And sometimes I really wish that the scope of variables inside a do-while-loop in C-ish lang

You provide some interesting thoughts. As for 1: This is not practically possible, and/or forces the government to artificially fix exchange rates between currencies, which would defeat the whole point. Why? Because huge parts of the l

The article talks a lot about one origin story of money, namely the one revolving around barter: roughly speaking, when there are N types of goods, you don't want to keep track of an NxN matrix of relative values of those goods; instea

The argument is that there are plenty of things that are obviously useful (or even needed) which aren't being done today because too many people incorrectly equate "useful" with "profitable" - and so only the profit

I find the article to be unfortunately meandering, but it contains an important question slightly more than half-way down: Why all the popular support for a Basic Income Guarantee rather than the arguably superior Job Guarantee (though the

Yes, that seems to be where sama is coming from. On the other hand, I suspect that this is again one of those truisms that may not really be true at all. Consider that in Europe (and to a lesser extent also in the US), mainstream academic e

It is not just social acceptance, though. It is also the problem that one's livelihood is closely tied to one's employment. With both these things, the question is how the social acceptance and the detachment of livelihood from

If they all run without containers, if one service gets compromised, and a root exploit is found, that's it game over. To be fair, if a kernel-level root exploit is found, it's probably also game over for containers. It's

RMS has an extreme stance, but it's actually quite refreshing that he just puts it out there in an easily digestable form. Taxis run "non free" software to process credit cards. And I think RMS cares less about that. No dou

You should care because a certain critical mass is needed to have a decent choice of properly supported hardware and software. There's no immediate need for worry on that front today, since we are well above this critical mass. However

Peyton-Jones is not the only person working on Haskell. In fact, if it were only Peyton-Jones working on Haskell, the language wouldn't be where it is today. Yes, the speed of development probably almost always scales sublinearly wit

I often wonder this as well. The speed of light isn't really a physical limit to expansion - generation ships are theoretically possible. It may just be that the Great Filter takes the form of relatively benign[1] economic and/o

The problem with the concept of "utility" as introduced by economists is that it is commonly used in a bait-and-switch. You can either use utility as a technical and unassailable term, taking it as axiomatic that humans are utilit

A really neat observation here is that Binet's formula and the matrix exponentiation trick are arguably the same thing. How so? You can think of the operations of Binet's formula as happening in the field Q(sqrt{5}). Since sqrt{5}

Your attempted defense of the US system is ineffective because it applies to all hidden fees. Any company ever that uses trickery to load additional fees on you could say, "well, you simply have to know the rules."
