"Cyber insurance" may reimburse the site operator for the liability they have to you for (say) being infested with malware. And that model seems to work OK for car accidents. But I think that only helps you (the site visitor) if

I have no idea what I'm talking about, but if you have a control flow translation pass that is intended to translate constructs like goto and produces "uglier" code, why not automatically disable it for functions (or whatever

To give an example, in a 2016 interview Sanders referred to open borders as a "right-wing" "Koch brothers proposal". Trump is worse, is that what you want to hear? I'm not trying to draw a moral equivalence. But I

If you want to know if a site is trustworthy , you want a certificate from their insurance company, not their CA. Someone who is promising to pay you real money if the site contains malware or a scam or whatever. Unfortunately this sort o

I'm not going to tell you that there won't be problems caused by increased migration. Anything that changes the world so much will cause problems. I'm not going to tell you that America's material wealth is the result of

I can't prove that there is no limit to how many migrants the first world could absorb without losing the rule of law, but it's pretty obvious that if there is such a limit it's higher than the status quo!

It's not exactly hard to find anecdotal evidence. For example, Haitian households living in the US had a 2015 median income of $47,200. I don't know exactly how to translate this into per capita terms, but Haiti has a per capi

I haven't read his book. But Borjas, who is to be clear a bit of an outlier among economists who have studied the problem, has in the papers I've looked at estimated that immigration is (slightly) a net economic negative for the

If people could migrate freely around the world to seek work, economists crudely estimate that world GDP would roughly double, and that most of this enormous windfall would go to the poorest people on Earth. There is literally a hundred tr

No, "exponentially faster" means exponentially faster with exponentially more hardware . Specifically, N processors can solve a problem of size N in O(log N) wall clock time, where the previous (serial) algorithm used O(N) wall

In this case, as I understand it, they also disabled the emergency braking feature built into the Volvo. Which wouldn't be obviously crazy if they had better, adequately tested emergency braking integrated with the "autonomy"

Deterministic code cannot receive a side channel. It may, as you point out, be able to transmit on a side channel. It might even be able to "reflect" one side channel into another one. But these risks seem both less severe

I'm familiar with this narrative, I'm saying that the evidence in the article, though the article is written by someone sympathetic to this point of view, contradicts it. The PE firms, despite their huge fees, lost a boatload of m

Despite the title and the focus on the form of financing, none of the facts in the article even suggested to me that the company would be in any better shape if it had used equity financing rather than debt. It sounds, rather, like an unpro

That isn't how tax deductions work. Even very tax efficient giving will not save you $1.00 of taxes when you give $1.00!

Determinism is related to purity ("functional programming"), but is a weaker notion. For example, this function var c = 0 function deterministic_not_pure() { return c++ } is not pure, and you can't r

Well, if with your best technology you can pack B bits of information in 1 m^3 of space, and you need to store N bits of information, you are going to need (N/B) m^3 of space to store it. And then the speed of light limits you to arou

The increasing latency [1] of access to larger amounts of storage isn't a constant factor, though, even asymptotically. There was a fun post on HN a while ago arguing that random access latency to N bytes is asymptotically O(N^0.5), fr

I've always wished for this in every communication medium. Charging someone for calling you would also block them permanently, so almost no one is going to do this to their friends just to mess with them. There should be no appeal: if

It looks to me like the original gradient based shading code is just wrong. Maybe there are numerical problems due to its frivolous use of trig functions, or more likely the way it calculates gradients is just broken. But shading based on

Yes, I agree, the article's approach will definitely win for small tables. But readers of this article may want to solve the same problem on big tables, so should be aware that there's an asymptotically faster solution. (Actually,

There is an asymptotic speedup available for this problem, to the extent that there are lots of prefixes in the table: a finite state automaton representing the regular expression ^(prefix1|prefix2|prefix3|...) can be matched against a len

Software prefetch can be a big win when doing a traversal that lets you predict random reads far enough in advance, which is generally not the case for linked list or tree traversals. (Since it's microarchitecture as well as data depen
