You're probably right, that's probably what was meant. I guess I'm so used to thinking geometrically about quaternions, I don't see much advantage to geometric algebra for 3D rotations (but geometric algebra does have ot

I don't understand the phrase "rotors operate fully in 3D". What does operating in 3D mean? If it means rotors can be used to give a simple formula for rotations in 3D space, then it also applies to quaternions. If it means t

> Most undergraduates take a compiler course in which they implement C, Java or Scheme. Is that true? I thought those compiler courses typically implemented some toy language. Maybe "in" is misplaced and the following was meant

This is off-topic in a discussion of silver bullets, but what advantages do you see in ido-style completion over icomplete? They feel very similar to me and icomplete is built-in, so I went with that.

I gauge projects based on recentness: recent for me suggests it's likely buggy, unoptimized and with an unstable interface. Is that what you meant?

I don't think tldr is a small CLI program unless you already have Node.js installed. :) And I also don't see why installing that is easier than installing man pages, if appropriately packaged. (I'm not claiming they are cur

I don't understand why this needs a client. Why not just install these as man pages in their own section and read them with man? EDIT: My idea is of course not new, see https://github.com/joelekstrom/tldr-man for

I think I agree with you if you change "dev only" to "prior Linux-user only" (I am a non-dev Linux-user and know plenty of others). Flatpak sounds worth exploring, although many of the cheaper Chromebook have pretty limi

I think I like the current Linux (Debian 9) in a VM approach: it's off by default, easy to turn on for people who want Linux, runs fast enough (for me at least), and is simultaneously fairly well integrated but isolated so you can&#x27

I think you meant to ask who would want to memorize the docs and never ever need confirmation they are remembering correctly?

Ooh! I don't think I've ever seen someone claim Chez Scheme produced faster code than SBCL before. That's interesting.

Maybe they are one of those people that can't help but comment that things should be rewritten in rust, but is also aware that doing so is annoying. Someone like that might want software to be already written in rust so they don't

Fixing the number of panes at 2 seems a little arbitrary. I used dired in emacs and open precisely the number of panes I want: most of the time 1, fairly often 2, once in a blue moon 3, and I've never needed 4.

I'm confused: how is dividing by zero an example of a leaky abstraction in mathematics?

My impression as a web user is that if any devs actually use the performance inspector it's just to learn their site is slow and then not do anything about it.

Julia is most comfortably used in the manner of a traditional Lisp: with a REPL open the entire time, sending snippets of code from your editor to the REPL for compilation, and then testing things out at the REPL. Sometimes people don'

I didn't know SBCL had an interpreter! (For those who didn't know either, see [1].) When would you use it? [1] http://www.sbcl.org/manual/#Interpreter

For future reference, code blocks here on HN use Markdown syntax (that is you indent them four spaces), not GitHub-Flavored Markdown syntax (triple backquotes).

Thanks for correcting me, I actually wasn't aware of nil coalescing in Swift and guessed it meant the same thing as optional chaining. The nil coalescing operator seems to correspond to Haskell maybe function, that is, a ?? b is comput

That's right, of course. I was just trying to convey the idea. But details matter of course. I was thinking of variables that either contained nil or contained an object with the appropriate field. If that precondition isn't meant

Something like a.?b.?c which is syntactic sugar for: a && a.b && a.b.c (with a short-circuiting &&.)

I know you probably mean it as a compliment to K&R, but you shouldn't compare K&R with S&W: while both are opinionated, the advice in K&R is coherent and sensible! S&W is a bizarre book: it's a pleasure to read
