2021-05-12 18:41:02 <monochrom> Pretty sure it was a joke.
2021-05-12 18:41:31 <deejaytee> The question or the subject? :P

2021-05-12 18:47:06 <tomjaguarpaw> bitonic: Sorry, I missed your message about Opaleye. The best way of getting my attention is to file an issue on Opaleye Github. But no, it doesn't support any binary format. In fact I didn't know there was one! I would be very encouraging of supporting it though. I guess the idea is that it has better performance? Anyway, if you want to discuss more please open an issue.
2021-05-12 18:47:50 <bitonic> tomjaguarpaw: no problem. yes, the idea is that it has better performance. we're dealing with ~10MB jsonb columns and it takes many seconds to roundtrip them
2021-05-12 18:47:54 <bitonic> i will open an issue

2021-05-12 18:50:22 <veverak> I am lost in this
2021-05-12 18:50:37 <veverak> I have `Double`, how to convert it to Scientific?
2021-05-12 18:50:52 <veverak> (I use Double for radians, library I am using expects Scientific)
2021-05-12 18:52:06 <tomjaguarpaw> fromFloatDigits? "Convert a RealFloat (like a Double or Float) into a Scientific number."
2021-05-12 18:52:18 <veverak> ah, yes
2021-05-12 18:52:26 <veverak> thanks, I was blind when reading the doc
2021-05-12 18:52:36 <tomjaguarpaw> Easy to do
2021-05-12 18:52:53 <bitonic> tomjaguarpaw: https://github.com/tomjaguarpaw/haskell-opaleye/issues/506 fairly nondescript issue, feel free to ask for more details (although i'm not an expert myself)
2021-05-12 18:54:13 <tomjaguarpaw> Oh, you are mazzo.li? Nice blog post on backpropagation!

2021-05-12 19:07:10 <grepcake> Is anyone familiar with async-pool? It seems to deadlock on pretty simple things, or maybe I'm misusing it. The example: https://paste.tomsmeding.com/g7D1u8vA. I have -threaded and -N4 specified, launch it as `stack test --ta "-m taskgroup"`

2021-05-12 19:29:36 <dminuoso> grepcake: There's something odd here, the second argument to withTaskGroup ought to be a function, not an IO value.
2021-05-12 19:31:04 <dminuoso> Does this really compile for you?
2021-05-12 19:31:26 × ram19890 quits (~ram@49.205.82.36) (Ping timeout: 240 seconds)
2021-05-12 19:32:20 <dminuoso> Ah, I suck at reading types today.

2021-05-12 19:36:59 <grepcake> dminuoso: you probably've figured it out, but it's an eta-reduced function, tg is implicit
2021-05-12 19:39:57 × xff0x quits (~xff0x@2001:1a81:523e:f300:f7bd:d435:471d:3982) (Ping timeout: 246 seconds)

2021-05-12 19:41:24 <dminuoso> main = print =<< withTaskGroup 4 acting where acting g = sum <$> mapConcurrently g pure [2,3,4,5,6]
2021-05-12 19:41:26 <dminuoso> Works fine for me
2021-05-12 19:43:16 × star_cloud quits (~star_clou@ec2-34-220-44-120.us-west-2.compute.amazonaws.com) (Ping timeout: 265 seconds)
2021-05-12 19:43:26 <grepcake> dminuoso: Yes, it works with mapConcurrently but not with Concurrently
2021-05-12 19:43:59 <grepcake> Moreover, it does work when the number of tasks is lesser than the pool capacity
