I’d phrase it as, “It’s not _just_ about floating point artefacts.” Rounding is a source of error inherent to storing arbitrary precision numbers in finite space, floating point numbers are just a very common way to do that. Numerical stabi

Hm, perhaps the answer is a subtle definition of "rounding error". A rounding error is when you have a number, lets say 0.75, and due to rounding it is recorded as 1.00. The "rounding error" is 0.25. An alternative to ro

The implication is that a secret is being revealed, possibly a dark secret to worry about. But FB and others put content in alt tags for people to read when they can’t see the images (for example die to blindness), it is much less dramatic

The implementation in the article still used hard-coded lengths, perhaps this could have been fixed without the extra markup after all.

Yea, that seems like a use-case I’ve felt like I wanted before. TypeScript supports this, as the JS output can be produced even if type checking fails, though in practice I have it turned off so that I don’t accidentally end up with type er

At least for me, that's the most interesting part of it. (0.125 isn't in the range I mentioned above though)

Hm, yes, perhaps "error" is still a good word for it. I'm not sure I understand what you mean by "holes", the idea is that all the real numbers between roughly 0.09999999999999999862 and 0.10000000000000001249 are r

I wonder about the terminology of calling these "errors". That implies that there's a mistake, when really floats are among the most accurate ways to represent arbitrary real numbers in a finite number of bits. Another way to

I wonder how much of this is a scam on the advertisers too, sure the platform might have great detail for targeting ads, but if someone comes along and outbids on generic terms it isn’t going to do you much good as an advertiser either.

In this context, yes, tests shouldn't require external dependencies. By "tests" we're really talking about tests like, "is this particular build consistent with its spec?" There could be other types of test whe

Yes, I avoided the “semantic” question as it seems very slippery, it could easily devolve to “Rust is turing complete so it is just the same as any other language”. Out of interest, do you have any examples that you would consider semantica

by DougBTX 7y ago
The way to answer your two questions is to combine them, the definition of “a while” depends on how good a job the interface does. If the interface is really good, then it can last a really long time (perhaps as long as the language lasts).

Basically yes. If an immediate mode API is much easier to use, and a retained mode underlying implementation has much better performance, then putting a React-style VDOM layer in-between could get the best of both worlds, depending on how w

Even with the hash set solution, it would be nice to not copy the string contents, which unfortunately is needed if the hash set contains lowercased versions of the strings. On the other hand, converting all strings to lowercase then compar

The output form this is a little different form the article, as it additionally requires: * that the uniqueness check is done case-insensitively, * that the casing from the first instance of the string in the input array should be used in t
