2020-09-26 17:00:42 → mu_ joins (~mu@unaffiliated/mu)
2020-09-26 17:00:49 <ski> fluturel : hm, perhaps i should also mention that normally it's not a good idea to use `!!' on lists, unless they're fairly short. the point is that random-access in (singly) linked lists is not instant, it has to traverse the list from the start to the place in question
2020-09-26 17:01:17 <ski> so, generally, one'd work with lists in other ways .. or switching to another data-structure, if one wants more efficient random-access
2020-09-26 17:01:37 <ski> but since you're just learning the basics, it's okay to use `!!', for now
2020-09-26 17:01:40 → oisdk joins (~oisdk@2001:bb6:3329:d100:4c4c:f42f:20c9:6844)
2020-09-26 17:02:12 × TooDifficult quits (~TooDiffic@106.206.110.145) (Ping timeout: 272 seconds)
2020-09-26 17:02:43 <c_wraith> I can think of approximately one idiom where !! stays relevant, and even it is sketchy
2020-09-26 17:02:47 <fluturel> yeah, i heard that haskell uses linked lists and figured that !! is bad for obvious reasons, but as of now, i have no other clue how to do this little exercise i challenged myself with
2020-09-26 17:03:05 <c_wraith> but when you're starting out, as ski says. don't worry about it.
2020-09-26 17:04:15 → jedws joins (~jedws@121.209.139.222)
2020-09-26 17:04:15 × mu_ quits (~mu@unaffiliated/mu) (Read error: Connection reset by peer)
2020-09-26 17:04:33 → mu_ joins (~mu@unaffiliated/mu)
2020-09-26 17:05:39 <ski> (hm, for `Maybe' values, `fromMaybe' could possibly also be nice to use. depending on how you structure your code)
2020-09-26 17:06:12 → v_m_v joins (~vm_v@2a02:aa12:3200:6480:f507:71a:9334:3099)
2020-09-26 17:06:20 × mmohammadi9812 quits (~mmohammad@188.210.108.97) (Ping timeout: 256 seconds)
2020-09-26 17:06:24 × Saten-san quits (~Saten-san@ip-213-49-124-100.dsl.scarlet.be) (Quit: WeeChat 2.8)
2020-09-26 17:08:22 <c_wraith> ski: did you see the person asking for style advice last night who ended up refactoring a big Maybe value into being generated by a do block? I suggested it, and was happy it ended up working out so cleanly.
2020-09-26 17:09:10 × jedws quits (~jedws@121.209.139.222) (Ping timeout: 272 seconds)
2020-09-26 17:10:44 × keteskyl quits (~kelsey@2600:6c64:7b7f:fa42:2cda:1ff8:55be:a617) (Quit: WeeChat 2.8)

2020-09-26 17:11:23 <Boarders> does anyone know how with hakyll what delimiters I use for inline latex?
2020-09-26 17:11:25 <svipal> yo
2020-09-26 17:11:37 <Boarders> for display mode I use $$ [equations] $$
2020-09-26 17:12:02 → cole-h joins (~cole-h@c-73-48-197-220.hsd1.ca.comcast.net)
2020-09-26 17:13:02 → Jeanne-Kamikaze joins (~Jeanne-Ka@static-198-54-131-92.cust.tzulo.com)

2020-09-26 17:13:25 <ski> c_wraith : hm, i didn't see it. any paste link which might still be valid ?
2020-09-26 17:14:09 <c_wraith> it's just out of my scrollback on this computer. I'd have to go to the other one and check my browser history :)
2020-09-26 17:14:10 × mu_ quits (~mu@unaffiliated/mu) (Read error: Connection reset by peer)
2020-09-26 17:14:10 <ski> (or approx. how many hours ago was it ?)
2020-09-26 17:14:12 → dhil joins (~dhil@11.29.39.217.dyn.plus.net)
2020-09-26 17:14:29 <c_wraith> so it was a bit over 10 hours ago
2020-09-26 17:14:33 → mu_ joins (~mu@unaffiliated/mu)
2020-09-26 17:15:54 <svipal> for some reason rtmidi ignores me changing the flags
2020-09-26 17:16:01 <svipal> in my stack.yaml
2020-09-26 17:16:07 <svipal> is it because it has external c bits
2020-09-26 17:17:17 → merijn joins (~merijn@83-160-49-249.ip.xs4all.nl)
2020-09-26 17:17:33 → kelsey joins (~kelsey@2600:6c64:7b7f:fa42:2cda:1ff8:55be:a617)
2020-09-26 17:17:37 <ski> c_wraith : hm, seems to be <https://paste.tomsmeding.com/7AifjNEN>,<https://paste.tomsmeding.com/dfCZuFjh>,<https://paste.tomsmeding.com/MO0geafX> ?
2020-09-26 17:17:57 kelsey is now known as Guest19180
2020-09-26 17:18:09 <c_wraith> yeah, those. The function in the third one is the rewrite
2020-09-26 17:18:13 × turion quits (~turion@ip5f5af77e.dynamic.kabel-deutschland.de) (Quit: Leaving.)
2020-09-26 17:18:41 × adam_wespiser quits (~adam_wesp@209.6.42.110) (Remote host closed the connection)
2020-09-26 17:19:18 → adam_wespiser joins (~adam_wesp@209.6.42.110)
2020-09-26 17:19:56 × Guest19180 quits (~kelsey@2600:6c64:7b7f:fa42:2cda:1ff8:55be:a617) (Client Quit)
2020-09-26 17:20:20 → kelsey1 joins (~kelsey@2600:6c64:7b7f:fa42:2cda:1ff8:55be:a617)
2020-09-26 17:21:48 kelsey1 is now known as keteskyl
2020-09-26 17:22:06 <ski> c_wraith : ah, yes. that does look quite nice :)
2020-09-26 17:22:22 <c_wraith> It's not often you get to do that, but I really enjoy when it works out.
2020-09-26 17:22:36 × merijn quits (~merijn@83-160-49-249.ip.xs4all.nl) (Ping timeout: 256 seconds)
2020-09-26 17:23:01 <ski> and the OP hopefully understood the use of `do' for `Maybe' here, and was pleased
2020-09-26 17:23:15 × keteskyl quits (~kelsey@2600:6c64:7b7f:fa42:2cda:1ff8:55be:a617) (Client Quit)
2020-09-26 17:23:30 <c_wraith> I mean, I suggested using a do block, but they did the rewrite themselves. Seemed plenty comfortable doing so.
2020-09-26 17:23:34 → kelsey1 joins (~kelsey@2600:6c64:7b7f:fa42:2cda:1ff8:55be:a617)

2020-09-26 17:26:09 → adam_wespiser joins (~adam_wesp@209.6.42.110)
2020-09-26 17:31:28 <ski> hm, i wonder what type of board game this is, whether there can be more than one empty position
2020-09-26 17:31:41 <ski> .. perhaps it's the "fifteen game"
2020-09-26 17:31:47 × chaosmasttter quits (~chaosmast@p200300c4a7105f0120adba39e14d4586.dip0.t-ipconnect.de) (Ping timeout: 240 seconds)

2020-09-26 17:32:23 <ski> (`applyOffset' could possibly also have use of having the result in a `Maybe')

2020-09-26 17:53:52 <nineonine> hey everyone
2020-09-26 17:54:04 <nineonine> I have a function for calculating binomial coefficient
2020-09-26 17:54:04 × mu_ quits (~mu@unaffiliated/mu) (Read error: Connection reset by peer)
2020-09-26 17:54:15 <nineonine> binomCoef :: Double -> Double -> Double
2020-09-26 17:54:15 <nineonine> binomCoef n k
2020-09-26 17:54:15 <nineonine> | n < 2 = 0
2020-09-26 17:54:17 <nineonine> | otherwise = fact n / ((fact (n-k)) * (fact k))
2020-09-26 17:54:19 <nineonine> where fact m = product [1..m]
2020-09-26 17:54:31 <nineonine> so when I play with it in ghci it works fine
2020-09-26 17:54:39 → Achylles joins (~Achylles@200-161-190-140.dsl.telesp.net.br)
2020-09-26 17:54:41 → mu_ joins (~mu@unaffiliated/mu)
2020-09-26 17:54:52 <nineonine> so binomCoef 21 2 => 210.0
2020-09-26 17:55:11 <nineonine> but when it is used deep in my program it returns different result
2020-09-26 17:55:29 <nineonine> it returns -17.46593177669282 for exact same arguments
2020-09-26 17:55:32 <nineonine> I am puzzled
2020-09-26 17:55:46 × vicfred quits (~vicfred@unaffiliated/vicfred) (Quit: Leaving)
2020-09-26 17:55:46 <nineonine> so the question is
2020-09-26 17:55:49 <nineonine> why?
2020-09-26 17:56:58 <nineonine> note, that the first guard in the function is specific to the problem which I am trying to solve so please ignore it
2020-09-26 17:57:26 <nineonine> the actual calculation is in second GRHS
