2020-10-29 17:20:16 <tomsmeding> then there is a good, working LSP client for vim
2020-10-29 17:20:23 × ubert quits (~Thunderbi@2a02:8109:9880:303c:ca5b:76ff:fe29:f233) (Remote host closed the connection)
2020-10-29 17:20:39 <tomsmeding> modus tollens produces the required conclusion
2020-10-29 17:20:56 → MindlessDrone joins (~MindlessD@unaffiliated/mindlessdrone)
2020-10-29 17:21:04 <monsterchrom> Does fintech simply mean blockchain stuff? It's a new term that suddenly popped up a few days ago and suddenly everyone except me knew it like it has always existed.
2020-10-29 17:21:16 <maerwald> but they have this obsession with hiring over-qualified ppl, which sometimes has interesting side-effects
2020-10-29 17:21:26 <tomsmeding> I understand it as high-frequency trading monsterchrom
2020-10-29 17:21:35 <maerwald> monsterchrom: no, I mean actual fintech, stealing real money
2020-10-29 17:21:54 → Guest84165 joins (~mrc@81.30.75.204)
2020-10-29 17:21:55 <thblt> Sounds way more honest than blockchain.
2020-10-29 17:22:03 × Guest84165 quits (~mrc@81.30.75.204) (Client Quit)
2020-10-29 17:22:05 × FreeBirdLjj quits (~freebirdl@101.228.42.108) (Ping timeout: 240 seconds)
2020-10-29 17:22:07 <tomsmeding> also less power usage probably
2020-10-29 17:22:25 <thblt> Where you steal money too, but after having had to lie to pretend it was money in the first place.
2020-10-29 17:23:06 <maerwald> I dunno. If you apply for a job and get it... didn't you steal it from the other 50 candidates? :)
2020-10-29 17:23:17 → solonarv joins (~solonarv@astrasbourg-653-1-117-122.w90-33.abo.wanadoo.fr)
2020-10-29 17:23:23 <monsterchrom> oh, financial technology
2020-10-29 17:23:35 <geekosaur> if people behave as if it has value, does it?
2020-10-29 17:24:25 <tomsmeding> for most reasonable definitions, yes
2020-10-29 17:24:31 × xff0x_ quits (~fox@port-92-193-232-58.dynamic.as20676.net) (Ping timeout: 265 seconds)
2020-10-29 17:24:59 <maerwald> But I can say it's interesting to have experienced real fraud once (not from employer, but customer)
2020-10-29 17:25:18 <avdb> A-mazing. I got the next three hours to play with Haskell for the first time in a while.
2020-10-29 17:25:41 <tomsmeding> avdb: what will you build?
2020-10-29 17:25:42 → teardown joins (~user@gateway/tor-sasl/mrush)
2020-10-29 17:27:46 × raichoo quits (~raichoo@213.240.178.58) (Quit: Lost terminal)
2020-10-29 17:27:47 × u0_a298 quits (~user@47.206.148.226) (Read error: Connection reset by peer)
2020-10-29 17:27:50 → idhugo joins (~idhugo@eduroam06.au.dk)
2020-10-29 17:28:48 → u0_a298 joins (~user@47.206.148.226)
2020-10-29 17:29:28 × Zetagon quits (~leo@c151-177-52-233.bredband.comhem.se) (Ping timeout: 260 seconds)
2020-10-29 17:29:41 <avdb> tomsmeding: I will be reading Chris' book since I can't even use Haskell properly yet.
2020-10-29 17:29:58 <avdb> I'm currently learning very slowlu due to bad time managment.
2020-10-29 17:30:01 <avdb> Slowly*
2020-10-29 17:30:15 <tomsmeding> as long as you're having fun, learning slowly is not an issue
2020-10-29 17:30:34 <carbolymer> I have: `counter <- newTVarIO 0` and in 2 threads I'm doing: `atomically $ modifyTVar' counter ((+)1) >> readTVar counter` and in both threads I'm getting 1 at the same time - WTF?
2020-10-29 17:30:40 → ensyde joins (~ensyde@99-185-235-117.lightspeed.chrlnc.sbcglobal.net)
2020-10-29 17:30:47 <maerwald> I'm a strong believer in slow learning
2020-10-29 17:31:24 <maerwald> if you learn slow, you forget slow :p
2020-10-29 17:31:27 hackage cassava-streams 0.3.0.5 - io-streams interface for the cassava CSV library. https://hackage.haskell.org/package/cassava-streams-0.3.0.5 (PeterJones)
2020-10-29 17:31:46 <tomsmeding> carbolymer: is the code shareable? https://paste.tomsmeding.com
2020-10-29 17:31:50 × merijn quits (~merijn@83-160-49-249.ip.xs4all.nl) (Ping timeout: 264 seconds)
2020-10-29 17:32:58 → st8less joins (~st8less@2603:a060:11fd:0:11a8:48f2:e89a:10e3)
2020-10-29 17:33:47 → merijn joins (~merijn@83-160-49-249.ip.xs4all.nl)
2020-10-29 17:35:04 × ensyde quits (~ensyde@99-185-235-117.lightspeed.chrlnc.sbcglobal.net) (Ping timeout: 240 seconds)
2020-10-29 17:35:10 <carbolymer> tomsmeding, not really, give a minute to re-create minimal example
2020-10-29 17:35:48 <tomsmeding> because from your description, #worksForMe :p
2020-10-29 17:35:56 <tomsmeding> (i.e. I get 1, 2)
2020-10-29 17:36:49 → xff0x_ joins (~fox@2001:1a81:528e:cb00:4e46:bded:683a:1262)
2020-10-29 17:39:20 <carbolymer> hmm, maybe it's because it's inside hunit test or ghc flags or idk - working on minimal example!
2020-10-29 17:39:52 <dminuoso> I suspect there's an unsafePerformIO you didn't tell us about.
2020-10-29 17:39:59 <tomsmeding> are you sure you have the same counter TVar both times?
2020-10-29 17:40:45 → thir joins (~thir@p200300f27f0b7e004c18ab60065ea01b.dip0.t-ipconnect.de)
2020-10-29 17:41:53 <carbolymer> tomsmeding, yes, because I'm running 5 threads, over 100 elements (everytime this function I pasted) and I am supposed to get 100 in return - but I get only 95
2020-10-29 17:42:02 <carbolymer> which = 100 - nr_of_threads
2020-10-29 17:42:07 <carbolymer> which is super weird
2020-10-29 17:42:38 × invaser quits (~Thunderbi@31.148.23.125) (Ping timeout: 264 seconds)
2020-10-29 17:42:53 × xwvvvvwx quits (~xwvvvvwx@185.213.155.160) (Ping timeout: 260 seconds)
2020-10-29 17:43:09 → emertens joins (x@freenode/staff/haskell.developer.glguy)
2020-10-29 17:43:10 <carbolymer> dminuoso, could be - might hidden by hunit internals
2020-10-29 17:43:34 <carbolymer> dminuoso, but I'm using pretty straightforward test spec
2020-10-29 17:44:16 <tomsmeding> do all the threads execute your code about the same number of times?
2020-10-29 17:44:40 → mbomba joins (~mbomba@142.114.9.241)
2020-10-29 17:44:58 hackage th-lego 0.2.2 - Template Haskell construction utilities https://hackage.haskell.org/package/th-lego-0.2.2 (NikitaVolkov)
2020-10-29 17:45:04 × thir quits (~thir@p200300f27f0b7e004c18ab60065ea01b.dip0.t-ipconnect.de) (Ping timeout: 240 seconds)
2020-10-29 17:45:17 × emertens quits (x@freenode/staff/haskell.developer.glguy) (Remote host closed the connection)
2020-10-29 17:45:17 × christo quits (~chris@81.96.113.213) (Remote host closed the connection)
2020-10-29 17:45:24 <carbolymer> tomsmeding, yes, I've added print after each invocation, and this function returns the same value two times at the very beginning
2020-10-29 17:45:51 <carbolymer> so, double 1's and numbers from 2-99
2020-10-29 17:45:56 <dminuoso> Im quite confident that stm is fine.
2020-10-29 17:46:16 <dminuoso> carbolymer: Are you creating the counter using unsafePerformIO perhaps?
2020-10-29 17:46:31 <carbolymer> dminuoso, no, newTVarIO
2020-10-29 17:46:38 <dminuoso> carbolymer: No from the outside.
2020-10-29 17:46:38 <carbolymer> inside IO
2020-10-29 17:46:45 <carbolymer> inside test spec
2020-10-29 17:46:49 <dminuoso> I stick to my theory "there's unsafePerformIO somehwere"
2020-10-29 17:47:32 <tomsmeding> carbolymer: can you post the test spec?
2020-10-29 17:47:50 <tomsmeding> despite knowing there's code we don't see
2020-10-29 17:48:33 → Tario joins (~Tario@201.192.165.173)
2020-10-29 17:48:34 <carbolymer> I can't - I would need to retype it from remote desktop; hold on, working on that example
2020-10-29 17:48:53 <tomsmeding> lol ok no worries
2020-10-29 17:49:06 <carbolymer> yeah, perks of remote work in financial company
2020-10-29 17:49:31 <geekosaur> here we go again with the fintech :p
2020-10-29 17:49:33 → xwvvvvwx joins (~xwvvvvwx@185.213.155.160)
2020-10-29 17:50:13 → christo joins (~chris@81.96.113.213)
2020-10-29 17:50:49 <monsterchrom> <backseat-driver>Just use ssh X forwarding</backseat-driver>
2020-10-29 17:50:58 hackage polysemy-methodology 0.1.2.1 - Domain modelling algebra for polysemy https://hackage.haskell.org/package/polysemy-methodology-0.1.2.1 (locallycompact)
2020-10-29 17:51:21 tomsmeding expects at least one of the two platforms involved to run windows
2020-10-29 17:51:57 geekosaur likewise
2020-10-29 17:53:07 <monsterchrom> I like to hedge-bet (haha fin again) the fantastically unlikely. I say OS/2 at the company and macOS at home. >:)
2020-10-29 17:53:17 <monsterchrom> I guess s/say/bet/
2020-10-29 17:54:06 <tomsmeding> does ghc even run on OS/2
2020-10-29 17:54:10 <dminuoso> Hey hey, why do people assume that fintech means financial technologies? What do you call companies specializing in making diver fins?
2020-10-29 17:54:14 <dminuoso> Surely you can use Haskell for that too
2020-10-29 17:54:22 <monsterchrom> Oh oops hehe
2020-10-29 17:54:38 <monsterchrom> I don't assume. I googled.
2020-10-29 17:54:49 × christo quits (~chris@81.96.113.213) (Ping timeout: 264 seconds)
2020-10-29 17:54:57 <carbolymer> ok, my minimal example works fine, I need to wrap it in test spec
2020-10-29 17:55:05 <geekosaur> should port readily
2020-10-29 17:55:09 <monsterchrom> Indeed I couldn't for my life figure out what's "fin" in "fintech", never occurred to me it's "finance"
2020-10-29 17:55:17 → Deide joins (~Deide@217.155.19.23)
2020-10-29 17:55:22 <dminuoso> or maybe its finnish tech!
