I mean, one way to look at it is that the energy density of this concrete supercapacitor, when fully charged, is about 4 orders of magnitude smaller than the chemical energy density of wood. So depending on the design, electrical shorts mig

An interesting counterpoint to this is the use of telepathy in Ursula K. Le Guin's Hainish cycle, which is generally considered as more "soft" sci-fi. Several of the early books in the series revolve around "mindspeech&q

This reminds me of the fact that Go 1.20 added a clever optimization: If you call `rand.Seed` to seed the global RNG, it's assumed that you want it to produce a single deterministic sequence across all threads/goroutines, which re

BitLocker encrypts the hard drive contents at rest , but while the system is booted, the drive is transparently decrypted. So what Microsoft says is technically true, but doesn't necessarily present any kind of barrier to the database

You can think of a full-text index as being like a vector database that's highly specialized and optimized for the use-case where your documents and queries are both represented as "bags of words", i.e. very high-dimensional

Maybe I'm not understanding the explanation, but how is a policy of "never wake up an idle core if another core is running code" different from "only ever allow one core at a time to be awake"? The latter could be a

Sorry, yeah, they didn't "acquire" the whole team in a business or employment sense, but my understanding is they got access to all the code and art assets they had created over the years.

I think you're confusing Riven with the original Myst. There have been full 3D versions of Myst since way back in 2000, but a real-time 3D remake of Riven has been a long-awaited pipe dream. There was a long-running fan project called

For P vs. NP to apply, you would have to be given a Turing machine (or equivalent program) that could verify a guess in polynomial time, without having to ask somebody. But how do you know that Turing machine couldn't be somehow revers

The most straightforward reason is that if you need a transactional database anyway, then moving the queue into the DB allows you to atomically en/dequeue messages at the same time as making other updates. Which can massively simplif

The details of the paper are way over my head, but here's what I took away from a quick skim. The random sampling technique of Benzur and Karger approximately preserves the total weights of all cuts in the graph, up to certain erro

This article makes two main arguments, both of which are (sorry to be blunt) just plain dumb. The first point is that the claim that "SQLite can support up to 281TB in a single database" is wrong, because in practice you can'

One of the biggest differences is that if you're using password auth, and you are tricked into connecting to a malicious server, that server now has your plaintext password and can impersonate you to other servers. If you use a diff

That's a fair point, but I don't consider that "cheating" any more than Hashlife [1] (which it's based on) is cheating. It's an ingenious trick that guarantees that what's displayed is exactly the same pat

Yes, this is legitimate, and there's no cheating. If you zoom in sufficiently, you can see that the "giant pixels" are really streams of spaceships, arranged in carefully positioned rows and columns that annihilate each other

Yeah, if you compress a tar file with gzip (or bzip2 or zstd or whatever) then the compressor doesn't care about the file boundaries, so it will be able to take advantage of redundancies. However, those compressors generally only have

No, the ZIP format compresses each embedded file separately , so it doesn't matter how much commonality there is between different files in the same archive.

The speed of light pretty much precludes anything happening to an entire star on a nanosecond timescale. In the other direction, it's basically a tautology. A "nova" or "new star" is, by definition , a relatively f

Those specks are almost certainly not distant satellites, but very nearby specks of dust and debris caused by the separation process. One dead giveaway is that they don't appear to be moving in perfectly straight lines. If they were di

Roughly speaking, both lift and drag are proportional to v^2 for a given geometry. Neither lift nor drag has anything to do with mass. They are entirely determined by the surface of the object, and are not affected at all by the interio

I mean, it makes sense. Rocket engines are machines for controlling the release of enormous amounts of stored energy. So, many of the failure modes can be broadly categorized as either "not enough energy" or "too much energy
