@dogjaw hey ya 😊

emacs and vi: Science of Command Efficiency http://ergoemacs.org/emacs/science_of_command_efficiency.html

so, the proper interpretation seems to be, that the topic of differential geometry really is deep, and tied with lots other advanced math. Therefore, even at 5 volumes, and being a comprehensive tome, is, still just a intro.

u wonder

you wonder, why's such book named “introduction”. It's actually graduate text, at 5 thick heavy volumes. Mathematicians not specialized in differential geometry have lots to learn from it, i assume.

but, “introduction” implies, this 5 volumes book only touches the surface. But then, its got the word “comprehensive” in it?

that's 5 volumes heavy expensive book. and, is graduate level.

seems that Jeff Atwood (aka codinghorror) is hit by sjw.

@zacts i think it's rather useless. It's one of the culty thing that hacker types want to glorify, since perl's inline doc pod of late 1990s. But among the few examples when they glorify, usually what they have is in no Knuth's literate programing, rather, just some inline doc of sorts.

@DrChris yes. am getting old ^_^. The real thing seems to be $80.

yet the haskell fuckheads's like, “algebraic” data structure and monoid and suff. Each one sounds like superior mathematicians. Monad ya ass.

there's no lang in practical use that has rigorous math-like doc or spec. #Haskell? #Ocamel? lol, they've the worst “grok it” doc and spec.

programers don't appreciate good docs. n they have this nasty concept of “grok” (from unix fuckheads), n in a flash they'll tell you to dig the source code.

been reading math 2 hours a day in past months. what a joy. In contrast of reading programing doc n lang specs. Programers are such idiots.

@yukiame $80

@yukiame lol. am getting old. the real thing seems to be $70

amazing. amazon is now telling $30 tablet. I suppose, they've calculated it's best to get you on the ship first. you can use it for nothing but photo display. http://amzn.to/2y2Ha1S

@panda_monium at 11:30, the woman broke out and went nuts herself. lol. love that part.
