Is that what this article is about? I read this article as being about a quantum phenomenon where the photon beam absorbed the momentum from an electron beam in a manner quite different from how they would interact at lower intensities.

That sort of works, in the http://blog.sigfpe.com/2008/12/mother-of-all-monads.html sense. Promises are an awkward encoding of continuations, and so they can encode all monadic structures. It sort of misses the po

You don't like the part where compiler authors are free to make efforts to improve the language that are clearly delineated as not part of the standard and easy to not enable if they prove to not be a good idea in practice? What are th

Any idea why the AI in your minesweeper sometimes doesn't declare it to be a local consideration that the one uncleared square adjacent to a 1 marker must be a mine? It's a funny hole in the final version of the game. I can't

To add even more detail, as there still appears to be a lot of confusion: The radar systems in these vehicles send out a radio pulse in a broad approximate-cone forward. They get bounces back from everything that reflects radio in front of

That's usually called an "online" algorithm, in my experience. It does seem to agree with the way it's used in this context.

So, you have no disagreement with my actual point?

You're asking for "an actual calculation" to back up a Fermi estimate of the true value of an irrationally-priced good? Of course there isn't one. It's a Fermi estimate. The main points were that the value is greate

My point was solely that there are ways to preserve x86-64 as an ISA, and listed the single most obvious way to go about it. I never suggested that it was the best solution, or that those changes would be made any time soon, or that Intel&#

Huh? It's a trustless timestamping service. That's a thing that some protocols benefit from. Digital notaries, for instance. That surely justifies a valuation around a few cents per bitcoin.

That's not exactly true. You could build an x86-64 chip without these flaws, but it would require a new internal architecture with a lot more silicon. One obvious approach would be to have two caches per core. Speculative execution

And just yesterday, I was thinking no one here would need to explain who Mike Judge is to the general audience. "It's got what plants crave" is a line from his movie Idiocracy. It is directly relevant the discussion at hand,

An official company party is not the private lives of anyone. That's the whole point of the article. It was an official company party. Edit: for what it's worth, there's also no consent possible when there's an external

The trailer makes it clear they're altering foundational details about the environment, including who the Envoy Corps even is. It still could be quite good, and I'm allowing my hopes to be high. But it will definitely be its own t

In order to be vulnerable, a system needs to run malicious code. This is an especially big deal in the context of virtual machines in shared hosting, because you have no idea what code is running in other virtual machines on the same host.

I have to admit you're moving past my level of knowledge on the topic. Both of your suppositions seem likely correct, but my understanding of the calculation technique involved is superficial at best.

Without the diffuser, the only information you have is roughly "a light ray hit the sensor at location (x, y)". You can't derive from that information what direction the photon hit the sensor from. This technique gives you &q

Were you using it to hash data for integrity? Or even worse, were you abusing it as a MAC [1]? That's the only way I can see it being so slow. PBKDF2 is a password-based key derivation function (it says so, right in the name), not a

It cannot possibly be anti-net-neutrality, because it is an action being taken by the user agent, not a transport.

Is your claim that capitalism is so magical that it justifies all abuses of the poor and weak done in its name?

Double leap-seconds are allowed, though I can't find any evidence one has ever happened. In such an occurrence, POSIX time would actually go backwards afterwards.

You're right, but phrasing things in terms of addition and zero is possibly taking some liberties with the definition of group. Even if additive groups and general groups are isomorphic, I agree it's a bit misleading to use additi

Also consider Dante https://github.com/jyp/dante instead of Intero. Similar (not identical, see the README for a quick overview) feature set, doesn't require stack.

Quickselect has an O(n^2) worst case, unless you use a variant like Tarjan's median-of-medians algorithm for selecting the pivot. And that does have awful constant factors.

You can respond with "that's because a good workman doesn't use poor tools." It nicely suggests that maybe it's the programmer's responsibility to advocate for something better.

Eh. Haskell is a general purpose Turing-complete language. Smart contracts need something far safer.

The easiest way to use JSON as dynamically typed data in Haskell is with the lens[1] and lens-aeson[2] packages. The type signatures those use are astounding, and not trivial to understand. But the code that results is very simple while rem
