Warp is a personal blog at warp.povusers.org about programming. Since 2010, 22 different Hacker News readers have linked it 33 times, most often “A response to Linus Torvalds on C++ (2007)”. No feed was found, so read it on the site itself.
Too few sampled comments (16) to say how often HN recommends it.?
Why HN links it
HN readers link this personal site of programming and science essays, including pages on bubble sort, the airfoil myth and C vs C++, plus a rebuttal to Torvalds. Commenters single out a few as well written or fun.
Summarised by Claude from a sample of 16 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
Paper airplanes fly, and they have flat wings! It turns out that flat wings work just fine, but the airfoil shape we see on airplanes is more efficient: http://warp.povusers.org/grrr/airfoilmyth.html

HN discussionYou're misidentifying the attitude. The problem is that Bubble Sort is a terrible algorithm, there's no reason not to use Insertion Sort or better instead except for some reason CS programs still inflict BS on students so that's what they remember when they just need to sort something. http://warp.povusers.org/grrr/bubblesort_eng.html http://warp.povusers.org/grrr/bubblesort_misconceptions.html (Bubble sort is not g…

HN discussionhttp://warp.povusers.org/grrr/bubblesort_eng.html >Teaching bubble sort as some kind of "basic sorting algorithm" has real-life negative consequences. This is a real-life example: this is a piece of code in the gnu flex program: /* We sort the states in sns so we * can compare it to oldsns quickly. * We use bubble because there probably * aren't very many states. */ bubble (sns, numstates); >There's absolutely no ra…

HN discussionThe best way that I know of to do this is the """ "Manual" export templates """ idea discussed here: http://warp.povusers.org/programming/export_templates.html (It's a great post in general. N.B. that it's also quite old and export templates have been removed from the standard for quite some time after compiler writers refused to implement them.) TL;DR: Declare your templates in a header, implement them in a source…

HN discussionI still prefer Japanese counting since it takes a lot less time to count (at least for me) a full 19x19 board. The only way white loses points (relative to black) by being forced to "play it out" is if black passes -- but the AGA resolves that by requiring you to give up a pass stone as a prisoner when you pass, and if the game has ended and you have to play it out, passes aren't allowed. The next AI challenge is to…

HN discussionHere's your informed person bashing C: http://warp.povusers.org/grrr/HateC.html (Disclaimer: I like C more than C++, though I can't say I love either of them.) I do think there are bad languages. Brainfuck is terrible. Maybe there are no bad serious languages, but you'll have to define what you mean by serious, and you'll have to argue with Dijkstra's ghost when it comes to COBOL et al. (though I think he would have…

It's made more horrible by the fact that a lot of substandard programmers use it, to the point where it's much much easier to generate total and utter crap with it. Quite frankly, even if the choice of C were to do nothing but keep the C++ programmers out, that in itself wo…
