13:45:17 <Zarutian> reepca-laptop: hmm.. right. Then I would use an switch statement to branch on the value from the code field of words
13:45:56 <reepca-laptop> sounds expensive
13:48:10 <Zarutian> why? if the wasm is being jit'ed or compiled then it is just one fetch and an indirect jump through a jump table
13:49:32 <Zarutian> sure it is 'expensive' as any meta morphic multi-exit branch is
13:51:26 <reepca-laptop> Ah, I forgot for a moment there that it's "web assembly", not "web machine code"
13:52:29 <reepca-laptop> I don't have too much experience with machine code, but so far I haven't heard of a switch instruction, only the software construct.
13:56:15 <Zarutian> I do not get why people want to get rid of ecmascript and then use crappy c++ instead so much
13:59:47 <Zarutian> I am squarely on the opinion that c++ is both under specified and over broad
14:00:19 <reepca-laptop> I'm no fan of c++ either, but I don't care for javascript either
14:00:49 <Zarutian> I think it is pretty good, for something that was thrown together in what ten days?
14:01:21 <Zarutian> the DOM can go and die in a fire though. Slow arse shit.
14:02:33 <Zarutian> I would have been rather estatic if he, the guy at netscape at the time whose name I do not recall, had said "fuck it" and gone with Scheme
14:04:28 <reepca-laptop> Zarutian: likewise
14:05:30 <Zarutian> are you like me that find traditional math notation confusing and often arbitrarily chosen?
14:05:54 <reepca-laptop> some of it
14:08:34 <Zarutian> for instance I took me a while to figure out an equation that described series sumnation of ?rotational-vector-endpoint-pathing?
14:09:06 <Zarutian> sorry, I do not know what they are called in English, but in Icelandic they are called vigrur
14:09:55 <Zarutian> basically you have one or more vectors of some lengths and treat them like the pointers of a clock
14:11:11 <Zarutian> as you rotate them around you put your pen a their outward pointy end and draw a path
14:12:51 <Zarutian> visually it isnt hard to grasp but the damn equation was just as obtuse as possible

15:48:45 <pierpa> revolution solids?
15:49:40 <pierpa> those things https://en.wikipedia.org/wiki/Solid_of_revolution ?
15:50:44 <Zarutian> pierpa: nope not quite. This happens on a 2d plane
15:50:58 <pierpa> hmmm
15:53:37 <Zarutian> continuing with the clock analogy, think of the pointers elongating and shortening depending where they happen to point
15:53:51 <pierpa> k
15:54:06 <Zarutian> if one pointer is just of a constant length you get a circle
15:54:47 <pierpa> got it
15:54:58 <Zarutian> well the path of its pointy end is a circle
15:57:02 <Zarutian> now, if we have three of these pointers 120­° apart and turning at the same speed then their pointy ends describe the same circle if the do not vary in length
16:00:17 <Zarutian> the problem this nasty equation came up in was to determine if the areas described (fitting verb no) by these three enclosing paths made by the vectors were of the same size
16:00:37 <pierpa> so, it's some kind of circular integral?
16:00:56 --- quit: X-Scale (Ping timeout: 240 seconds)
16:00:57 <Zarutian> yeah, you might call it that
16:01:44 <pierpa> anyway, yes, mathematical notation generally sucks :)
16:02:15 <Zarutian> basically it was a question on Alternating Current power production and consumption. Mostly to see if the generator would have ?wobble stress?.
16:02:27 <pierpa> ah! ok
16:02:57 <pierpa> understood the problem
16:03:28 <Zarutian> the three vectors are basically the three poles of the three phase AC generator.
16:03:35 <pierpa> yes
16:03:59 <Zarutian> it is bloody obvious if you just plot as described above

18:36:05 <KipIngram> Hey guys, I was just able to do a timing test on a lodsd based next vs. a mov / add based one.
18:36:24 <KipIngram> lodsd is faster by 33 picoseconds (per execution of NEXT).
