I wonder if building this table can be sped up by noticing a recurring pattern? x 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 ... 254 255 f(x) 0 0 1 2 3 3 4 5 6 6 7 8 9 9 10 11 12 12 ... 190 191 So some

I think I actually saw a question on SO way back during the Windows Vista era when some guy asked if Windows supported machines with odd number of cores/processors, and the answer was "well, 1 is an odd number, you know". Ano

Well, no. But I think it wouldn't be that hard to add to e.g. Golang, the code gen for this feature is pretty small: find the closest wrapping loop, put "$unique_name := true" as the first statement of its body, replace the k

Or we can go the OCaml route, admit that we want both applicative and generative functors, and add an explicit marker to the type-returning functions whether those generated types should always have unique identity, or not.

It only has to count if the index doesn't store the amounts of records in the "chunks" it manages, does it? I'm pretty sure B-trees do actually store the sizes of the subtrees.

Well, IIRC using the >>/<< operators for I/O was proposed by McIlroy (who also invented the Unix pipes), and Stroustrup liked it enough to adopt. And, well, I personally don't really mind it. What I do mind is t

You're correct, of course, but back in 1990 people were way more excited about overgeneralizations, class hierarchies and what templates could possibly do. I mean, that was the time when using << and non-stacking stream manipulat

I personally think it's the influence from Pascal, it had the "SET OF" types that were conventionally implemented as bitsets, so you didn't have to muck around with manual shifting/masking yourself.

Seriously, please don't use C0 (except for LF and, I cede grudgingly, HT) and C1 characters in your plain text files. I understand that you may want to store some "ANSI coloring markup" (it's not "VT100 colors"

Or, to re-word it in the words of the parent comment, that's why we don't write write programs in assembler that output even more assembler.

Well, there is also a question of attitude. Most of the Python programmers don't overload << or >> even though they technically can, while in C++ that's literally the way the standard library does I/O ― and I su

And if you underspecify, you force the users to invent their own hacks and workarounds, often very poorly. And no, I don't want to "high performance" lock implementations that regularly completely deadlock the whole process (
