[2021-12-01T04:08:09Z] <midfavila-laptop> no, I still have the getac [2021-12-01T04:08:13Z] <midfavila-laptop> i just don't use it as my main machine [2021-12-01T04:08:18Z] <acheam> also this lora thing looks pretty cool [2021-12-01T04:08:20Z] <acheam> oh I misread [2021-12-01T04:08:21Z] <midfavila-laptop> it's gonna be going into the kitchen soon as a terminal [2021-12-01T04:08:26Z] <midfavila-laptop> and yes, lora is very nifty [2021-12-01T04:08:27Z] <acheam> "I used to use" as "I used to have" [2021-12-01T04:08:41Z] <midfavila-laptop> i helped the civil engineering corps deploy a LoRa network a few years ago [2021-12-01T04:09:00Z] <midfavila-laptop> for monitoring the tide of the river and distributing information about flooding and shit [2021-12-01T04:09:09Z] <midfavila-laptop> that was fun [2021-12-01T04:09:19Z] <hyrc> what's a supercheap low power lora board [2021-12-01T04:09:32Z] <midfavila-laptop> raspi zero with a lora module slapped on top [2021-12-01T04:09:52Z] <noocsharp> doesn't pine have some [2021-12-01T04:09:57Z] <midfavila-laptop> maybe? [2021-12-01T04:10:00Z] <midfavila-laptop> also hi noocsharp [2021-12-01T04:10:05Z] <midfavila-laptop> you're a math nerd right [2021-12-01T04:10:11Z] <noocsharp> hello, perhaps [2021-12-01T04:10:18Z] <midfavila-laptop> have you ever read any of serge lang's books [2021-12-01T04:10:28Z] <acheam> ha nerd! [2021-12-01T04:10:38Z] <midfavila-laptop> thank you acheam [2021-12-01T04:10:58Z] <noocsharp> i think i briefly wanted to read his number theory book a few years ago, downloaded it an never did [2021-12-01T04:11:04Z] <hyrc> i wouldn't need that much computer tho [2021-12-01T04:11:11Z] <hyrc> stm32 or something would be fine [2021-12-01T04:11:16Z] <midfavila-laptop> aw, unfortunate. i wanted to ask a mathy person what they thought of his work [2021-12-01T04:11:22Z] <hyrc> just relay some sensor data [2021-12-01T04:11:24Z] <midfavila-laptop> i've been reading his "Basic Mathematics" lately [2021-12-01T04:11:37Z] <noocsharp> what does it cover? [2021-12-01T04:11:39Z] <midfavila-laptop> hyrc can't you just program a microcontroller then? [2021-12-01T04:12:02Z] <midfavila-laptop> noocsharp everything in a K-12 mathematics program as well as first-year college maths, complete with proofs [2021-12-01T04:12:02Z] <hyrc> yeah is there like a lora radio card with microcontroller and solar panel or somethin [2021-12-01T04:12:20Z] <hyrc> that can send a few bytes per minute [2021-12-01T04:12:23Z] <midfavila-laptop> so arithmetic, algebra, euclidean geometry, basic calculus, trigonometry, etc [2021-12-01T04:12:30Z] <midfavila-laptop> hyrc you'll probably have to make that [2021-12-01T04:12:33Z] <midfavila-laptop> i can't see it being hard though [2021-12-01T04:12:47Z] <midfavila-laptop> if you want it to be Extra Reliable:tm: use an RCA CDP1802A [2021-12-01T04:13:03Z] <midfavila-laptop> it's eight-bit but it's also shielded against electrostatic discharge and radiation [2021-12-01T04:13:09Z] <midfavila-laptop> and it's fairly cheap [2021-12-01T04:13:23Z] <midfavila-laptop> gonna make myself a microcomputer based on it [2021-12-01T04:13:50Z] <midfavila-laptop> although I'd really rather modify it to be thirty-two bit so that it can have a flat address space... [2021-12-01T04:14:01Z] <noocsharp> what was the last math book that you worked through? [2021-12-01T04:14:14Z] <midfavila-laptop> well, I'm working through Basic Mathematics right now [2021-12-01T04:14:22Z] <noocsharp> before that [2021-12-01T04:14:30Z] <midfavila-laptop> as well as George Simmons' "Precalculus in a Nutshell" [2021-12-01T04:14:30Z] <midfavila-laptop> and before that? elements of algebra [2021-12-01T04:14:38Z] <midfavila-laptop> although I didn't finish elements of algebra [2021-12-01T04:14:45Z] <midfavila-laptop> because the translation isn't modern english [2021-12-01T04:14:59Z] <midfavila-laptop> it's hard enough to self-teach mathematics without having to also interpret archaic grammar [2021-12-01T04:16:43Z] <midfavila-laptop> but yeah, I'm gonna be working through those while also making regular tests for myself referencing James Stewart's precalc text, as well as Spivak's [2021-12-01T04:17:38Z] <noocsharp> i worked through spivak, i think stewart was used in the precalc class at my high school [2021-12-01T04:17:47Z] <midfavila-laptop> there's a book on proofs I want to get, as well, since I'm having some trouble grasping how proofs work [2021-12-01T04:17:47Z] <midfavila-laptop> what do you think of them? [2021-12-01T04:17:52Z] <midfavila-laptop> the books, not proofs [2021-12-01T04:18:24Z] <noocsharp> what are you having trouble grasping about proofs? [2021-12-01T04:18:37Z] <noocsharp> i liked spivak [2021-12-01T04:18:45Z] <noocsharp> no opinion on stewart [2021-12-01T04:18:50Z] <midfavila-laptop> well, for some stuff, I just don't get how it... proves things [2021-12-01T04:19:07Z] <noocsharp> logs pls [2021-12-01T04:19:21Z] <noocsharp> (like what?) [2021-12-01T04:19:25Z] <midfavila-laptop> there was a geometric proof for the pytagorean theorem for example that tiled right triangles such that they were arranged in a square [2021-12-01T04:19:29Z] <midfavila-laptop> and then the book was like [2021-12-01T04:19:36Z] <midfavila-laptop> "this proves the pythagorean theorem" [2021-12-01T04:19:40Z] <midfavila-laptop> and I was just like [2021-12-01T04:19:44Z] <midfavila-laptop> "wtf" [2021-12-01T04:20:02Z] <noocsharp> think about what the pythagorean theorem says [2021-12-01T04:20:51Z] <midfavila-laptop> the proof itself makes sense, but... idk I'm having a hard time articulating it exactly [2021-12-01T04:21:11Z] <noocsharp> the a square with the length of the hypotenuse has the same area as the sum of the areas of squares with side lengths as the legs of the triangle [2021-12-01T04:21:20Z] <noocsharp> s/the a/a/ [2021-12-01T04:21:41Z] * midfavila-laptop shrugs [2021-12-01T04:21:53Z] <midfavila-laptop> i'm just gonna work through a dedicated book of proofs [2021-12-01T04:22:12Z] <midfavila-laptop> because the whole thing is just kind of vaguely defined and touched-on in my current books [2021-12-01T04:22:16Z] <noocsharp> it's very cool because it turns the concept of a square of a number into a concrete geometric thing [2021-12-01T04:22:31Z] <midfavila-laptop> yeah, i've learned to appreciate geometry as a way of connecting statements to algebra [2021-12-01T04:22:56Z] <noocsharp> a proof is simply a rigorous argument [2021-12-01T04:23:45Z] <midfavila-laptop> mmh. i think the two main types of proof used are proofs from absurdity and proofs from axioms... can't recall the actual term for the latter atm [2021-12-01T04:23:49Z] <midfavila-laptop> it's been a long day [2021-12-01T04:23:57Z] <midfavila-laptop> deductive reasoning or whatever [2021-12-01T04:24:32Z] <noocsharp> a proof is a proof, reductio ad absurdum is still deduction [2021-12-01T04:24:45Z] <midfavila-laptop> no, I'm thinking of *inductive*. deductive is the other way around, durr [2021-12-01T04:24:56Z] <noocsharp> an inductive proof is still deductive [2021-12-01T04:25:11Z] <midfavila-laptop> well, fair enough, I guess [2021-12-01T04:25:14Z] <noocsharp> induction is just a technique used in deduction [2021-12-01T04:25:25Z] <noocsharp> (the mathematical sense of induction) [2021-12-01T04:25:42Z] <midfavila-laptop> yeah [2021-12-01T04:25:51Z] <midfavila-laptop> induction is the specific term for what I was thinking of [2021-12-01T04:26:01Z] <midfavila-laptop> applying axioms to derive more complex axioms [2021-12-01T04:26:44Z] <midfavila-laptop> even if I don't become spectacular with mathematical concepts I'd at least like to be competent [2021-12-01T04:29:07Z] <midfavila-laptop> oh, by the way, acheam, you might or might not find these useful [2021-12-01T04:29:09Z] <midfavila-laptop> http://aduni.org/courses/ [2021-12-01T04:29:13Z] <midfavila-laptop> in particular the unix workshop [2021-12-01T04:30:20Z] <acheam> midfavila-laptop: bookmarked, thanks! [2021-12-01T04:30:24Z] <midfavila-laptop> np [2021-12-01T04:30:28Z] <noocsharp> noble goal, but as you've heard from me before, the best way to learn these things is not textbooks but finding ways to apply things in real life [2021-12-01T04:30:55Z] <midfavila-laptop> oh, definitely. it's unfortunate that I can't come across more organic applications of some of the concepts I've learned [2021-12-01T04:30:57Z] <hyrc> to do some things in real life you need a foundation though [2021-12-01T04:31:01Z] <midfavila-laptop> also that [2021-12-01T04:31:36Z] <midfavila-laptop> i've been using lisp instead of a calculator while working on problems so to test my understanding of functions and concepts I've been working on a homebrew math library, which is at least something [2021-12-01T04:31:37Z] <noocsharp> go write a program to evaluate a riemann sum or something [2021-12-01T04:31:55Z] <midfavila-laptop> i don't even know what a riemann sum is [2021-12-01T04:32:02Z] <midfavila-laptop> reminder that I'm actually a mathlet [2021-12-01T04:32:26Z] <noocsharp> you'll find out soon enough [2021-12-01T04:32:45Z] <midfavila-laptop> looks like it's something to do with calc, so hopefully [2021-12-01T04:33:08Z] <midfavila-laptop> once I've become decent with single-variable calculus I think I'll be able to call myself at least numerate. that's the big goal right now [2021-12-01T04:33:40Z] <midfavila-laptop> arithmetic, then algebra and geometry, then trigonometry and graphing stuff, probability and stats, then calculus and... from there idk [2021-12-01T04:33:46Z] <acheam> its usually taught in calc courses, but you could probably learn it now if you wanted to [2021-12-01T04:33:52Z] <midfavila-laptop> doubtful [2021-12-01T04:34:48Z] <noocsharp> do you know what a derivative is? [2021-12-01T04:34:57Z] <midfavila-laptop> the opposite of an integral [2021-12-01T04:35:08Z] <acheam> do you know what an integral is? [2021-12-01T04:35:11Z] <midfavila-laptop> nope [2021-12-01T04:35:12Z] <midfavila-laptop> no clue [2021-12-01T04:35:26Z] <midfavila-laptop> i only took up to tenth grade geometry before the pandemic happened [2021-12-01T04:35:39Z] <midfavila-laptop> i have a lot of ground to cover [2021-12-01T04:36:09Z] <noocsharp> a derivative of a function at a point is the limit of the approximation of slope at that point [2021-12-01T04:36:38Z] <noocsharp> so its just a function that gives you the slope of the original function at some x value [2021-12-01T04:36:44Z] <midfavila-laptop> i see. [2021-12-01T04:37:04Z] <midfavila-laptop> once I have a deeper understanding of functions and their graphs I'm sure I'll appreciate your explanation more [2021-12-01T04:37:08Z] <noocsharp> the integral is the area between the x-axis and the graph of a function [2021-12-01T04:37:16Z] <noocsharp> there, you now know calculus [2021-12-01T04:37:29Z] <midfavila-laptop> declaratively, maybe [2021-12-01T04:39:27Z] <noocsharp> do you know what the slope of a function is? [2021-12-01T04:39:30Z] <noocsharp> at a point? [2021-12-01T04:39:57Z] <midfavila-laptop> i do not. like I said, my formal mathematics education never finished a tenth-grade level [2021-12-01T04:40:06Z] <midfavila-laptop> and even then I was taught poorly [2021-12-01T04:40:17Z] <midfavila-laptop> embarassing to admit, honestly. [2021-12-01T04:40:30Z] <noocsharp> do you know what a tangent line is? [2021-12-01T04:40:40Z] <acheam> the slope is just the rate of change of the function. So if the slope of a line is 2, then for every 1 unit a line moves in the X direction, it increases 2 in the Y direction [2021-12-01T04:40:53Z] <midfavila-laptop> Ah. [2021-12-01T04:40:58Z] <acheam> tangent lines usually come after learning slope, at least they did in my curriculum [2021-12-01T04:41:11Z] <midfavila-laptop> Yeah, slope was the last thing I recall learning... [2021-12-01T04:41:48Z] <noocsharp> well i asked because tangent lines are easy to understand conceptually [2021-12-01T04:42:24Z] <noocsharp> actually nvm, probably makes sense to define in terms of slope [2021-12-01T04:42:34Z] <midfavila-laptop> gonna point out that it's like [2021-12-01T04:42:35Z] <midfavila-laptop> 1am [2021-12-01T04:42:39Z] <midfavila-laptop> and my brain is fried right now [2021-12-01T04:42:47Z] <acheam> stfu its 12:42 [2021-12-01T04:42:57Z] <noocsharp> stfu its 10:42 [2021-12-01T04:43:14Z] <midfavila-laptop> - w- [2021-12-01T04:43:20Z] <acheam> ugh mountain timers [2021-12-01T04:43:25Z] <midfavila-laptop> anyway, I just need to study more [2021-12-01T04:43:28Z] <midfavila-laptop> that's the conclusion I've reached [2021-12-01T04:43:31Z] <acheam> you dont even live near a mountain [2021-12-01T04:43:32Z] <noocsharp> cst [2021-12-01T04:43:55Z] <acheam> oh yeah [2021-12-01T04:44:08Z] <acheam> for some reason I thought 11-10=2 [2021-12-01T04:44:19Z] <midfavila-laptop> big rip [2021-12-01T04:44:25Z] <midfavila-laptop> that makes me feel a little better :P [2021-12-01T04:44:27Z] <acheam> mid, got any good books on preschool level arithmatic? [2021-12-01T04:44:33Z] <midfavila-laptop> i mean [2021-12-01T04:44:38Z] <noocsharp> learn to count with elmo [2021-12-01T04:44:40Z] <midfavila-laptop> serge lang starts out by teaching you how to count [2021-12-01T04:44:46Z] <midfavila-laptop> with proofs [2021-12-01T04:45:02Z] <midfavila-laptop> and then in ten pages he's moved on to talking about factorials and shit [2021-12-01T04:45:05Z] <midfavila-laptop> which is kind of amusing [2021-12-01T04:45:26Z] <acheam> damn how could I forget about elmo [2021-12-01T04:45:29Z] <noocsharp> well factorials are pretty important for counting [2021-12-01T04:45:36Z] <midfavila-laptop> oh, definitely [2021-12-01T04:45:43Z] <Denshi> yeah [2021-12-01T04:45:49Z] <Denshi> so is a fundamental grasp of linear algebra [2021-12-01T04:45:54Z] <midfavila-laptop> it's just amusing how he covers basically an entire k-10 education in as many pages [2021-12-01T04:45:56Z] <Denshi> vector addition is essential for preschool knowledge [2021-12-01T04:46:02Z] <midfavila-laptop> fuck [2021-12-01T04:46:06Z] <midfavila-laptop> i'm going back to preschool i guess [2021-12-01T04:46:14Z] <midfavila-laptop> four year old me is literally a dumbass [2021-12-01T04:47:03Z] <noocsharp> math textbooks often start out with chapters on what is supposed to be prerequisite knowledge [2021-12-01T04:47:10Z] <hyrc> in a sense you're doing it when you catch a ball, yes Denshi :) [2021-12-01T04:47:17Z] <midfavila-laptop> oh, well, yeah, that makes sense [2021-12-01T04:47:41Z] <midfavila-laptop> but this book doesn't make any assumptions about requisite knowledge other than decent reading comprehension, I would say [2021-12-01T04:48:19Z] <noocsharp> well that goes for many math textbooks, but a terse chapter on prerequisites may not be the best learning material [2021-12-01T04:48:23Z] <noocsharp> just review [2021-12-01T04:48:42Z] <midfavila-laptop> the arithmetic/algebra chapter is the longest one in the book last I checked [2021-12-01T04:49:00Z] <midfavila-laptop> most chapters are no larger than maybe twenty pages [2021-12-01T04:49:08Z] <midfavila-laptop> complete with proofs and exercises [2021-12-01T04:49:27Z] <midfavila-laptop> my only complaint with it is that the bastard didn't include a full answer key [2021-12-01T04:49:58Z] <noocsharp> tbh go grind khanacademy for a year [2021-12-01T04:50:04Z] <noocsharp> that should get you up to speed [2021-12-01T04:50:10Z] <midfavila-laptop> i worked on KA for about three months during the summer [2021-12-01T04:50:15Z] <midfavila-laptop> i remember almost none of it [2021-12-01T04:50:46Z] <midfavila-laptop> the material lacks substance. that and it was also like 40C+ in my apartment [2021-12-01T04:51:07Z] <midfavila-laptop> ...and I was sleep deprived, and there was a lot of shit happening, but point is, I didn't benefit as much from it as I have from my texts [2021-12-01T04:51:08Z] <noocsharp> wdym lacks substance [2021-12-01T04:51:51Z] <midfavila-laptop> well, there's not as many exercises as I would like, nor are there step-by-step proofs for things. not that KA is a bad resource because of either of those, especially the latter, but I do appreciate my texts as a primary resource [2021-12-01T04:51:59Z] <midfavila-laptop> KA would shine as a secondary resource, I think [2021-12-01T04:52:07Z] <noocsharp> it's probably the sleep deprivation and 40C+ that caused you to not remember anything [2021-12-01T04:52:11Z] <midfavila-laptop> yeah [2021-12-01T04:52:20Z] <midfavila-laptop> anything about 20C and I just melt [2021-12-01T04:52:23Z] <midfavila-laptop> above* [2021-12-01T04:52:54Z] <testuser[m]> Bruh [2021-12-01T04:52:56Z] <noocsharp> haha 20C [2021-12-01T04:53:07Z] <midfavila-laptop> look I'm canadian [2021-12-01T04:53:11Z] <midfavila-laptop> give me -20 and I'm fine [2021-12-01T04:53:14Z] <midfavila-laptop> give me 20 and I die [2021-12-01T04:53:17Z] <midfavila-laptop> what do you want [2021-12-01T04:53:45Z] <midfavila-laptop> i fucking hate my province so much though. it has an 80-100C temperature gradient [2021-12-01T04:53:55Z] <midfavila-laptop> -40 to 40 on average with extremes

[2021-12-01T06:21:42Z] <natris1979[m]> Windows -> WSL -> Arch -> Kiss chroot might be it :D [2021-12-01T06:21:52Z] <natris1979[m]> oh wait, you said when you'd need it :D [2021-12-01T06:24:57Z] <natris1979[m]> hmmm. on arch if I do `df -h1, I have `/run/shm` instead of `/dev/shm` I wonder if I need to mount kiss's `/dev/shm` to that [2021-12-01T06:25:41Z] <natris1979[m]> oof, messed up the tickmarks there [2021-12-01T06:30:09Z] <hyrc> on my system /run/shm is symlinked to /dev/shm [2021-12-01T06:30:29Z] <hyrc> it's used for some kind of interprocess communication [2021-12-01T06:30:29Z] <natris1979[m]> yup, here too. mounting directly didn't help [2021-12-01T06:30:46Z] * hyrc waves hands in air vaguely [2021-12-01T06:31:03Z] <natris1979[m]> that's currently my level of understanding too :) [2021-12-01T06:45:09Z] <natris1979[m]> Yes! [2021-12-01T06:45:12Z] <natris1979[m]> I did it! [2021-12-01T06:45:38Z] <natris1979[m]> just had to create /mnt/kiss/dev/shm with the right permissions and it worked! [2021-12-01T06:48:34Z] <natris1979[m]> needed to do `mkdir /mnt/kiss/dev/shm` then `chmod +t /mnt/kiss/dev/shm` and `chmod 777 /mnt/kiss/dev/shm`. Mounted it same a the other stuff cribbed from kiss-chroot with ` mmount "$1/dev/shm" -o bind /dev/shm` [2021-12-01T06:50:11Z] <natris1979[m]> for anyone else in IRC logs trying to do this, I also had to similarly mount /mnt/wslg into the chroot (and /mnt/wsl, but I'm unsure if that was needed) [2021-12-01T06:52:06Z] <natris1979[m]> Then I had to set the folllowing ENV variables `DISPLAY=:0`, `XDG_RUNTIME_DIR=/mnt/wslg/runtime-dir` and `export WAYLAND_DISPLAY=wayland-0` [2021-12-01T06:53:33Z] <natris1979[m]> thanks hyrc and testuser for letting me bounce ideas of you. Now I need to try to sleep when I super excited [2021-12-01T06:53:43Z] <natris1979[m]> *off of you [2021-12-01T06:54:10Z] <natris1979[m]> *I'm [2021-12-01T06:54:20Z] <testuser[m]> Np [2021-12-01T06:54:22Z] <hyrc> glad you made progress [2021-12-01T06:54:53Z] <natris1979[m]> "progress" he says. I solved it :D :p [2021-12-01T06:55:50Z] <natris1979[m]> I'm just glad I'll be able to use a half way decent window manager outside of a (traditional) vm or dual booting [2021-12-01T08:14:54Z] <testuser[m]> > [400/49394] [2021-12-01T08:14:59Z] <testuser[m]> adding 5000 new targets every release [2021-12-01T08:15:00Z] <testuser[m]> bruh [2021-12-01T08:15:32Z] <testuser[m]> 100k by 2023 [2021-12-01T08:30:51Z] <phoebos> oof [2021-12-01T08:31:07Z] <phoebos> ah you're right acheam i didn't need the lambda wrapper [2021-12-01T08:31:37Z] <phoebos> initially i had too many parentheses so the function was trying to execute the result of the calculation as a function [2021-12-01T08:32:26Z] <testuser[m]> bruh [2021-12-01T09:48:52Z] <phoebos> maybe i'll try to do some of the advent of code problems in scheme [2021-12-01T09:49:28Z] <phoebos> that way by the end of december i should be almost able to write decent code [2021-12-01T11:09:09Z] <testuser[m]> noocsharp: https://github.com/kiss-community/bin/commit/a3673a652d708b3bb79467cc5aad63d7f8a4dc55 [2021-12-01T11:57:27Z] <bibliocar> sometimes things just confuse me. [2021-12-01T11:57:57Z] <testuser[m]> wat [2021-12-01T11:58:50Z] <bibliocar> I was looking at the musl sin function. Oh, nothing kiss related, really. I just thought I'd share my confusion at "return x - x;" in the musl sinf function. [2021-12-01T11:59:18Z] <bibliocar> I assume it's some weird floating point magic to return the correct error value or something. [2021-12-01T12:01:08Z] <testuser[m]> > sin(Inf or NaN) is NaN [2021-12-01T12:01:19Z] <testuser[m]> if u gonna return nan then why not just return x which is already a nan [2021-12-01T12:01:22Z] <testuser[m]> ask in #musl irc [2021-12-01T12:01:31Z] <testuser[m]> this is taken from freebsd anyways [2021-12-01T12:01:43Z] <testuser[m]> > trig(+-INF) is NaN, with signals; [2021-12-01T12:01:44Z] <testuser[m]> maybe this [2021-12-01T12:01:48Z] <testuser[m]> idk what a "signal" is here [2021-12-01T12:02:02Z] <bibliocar> I'm not smart enough to ask in #musl [2021-12-01T12:02:17Z] <bibliocar> maybe not smart enough to ask here either... I dunno. [2021-12-01T12:02:30Z] <bibliocar> It wasn't important [2021-12-01T12:03:09Z] <bibliocar> I was just observing that even though C is pretty basic, there's still some nuances that still confuse me.
