00:26:18shodan45I assume nobody has tried to improve nim's results in that
00:27:33shodan45but even still, nim/jester does surprisingly poorly
00:29:31shodan45I don't understand how interpreted languages are out performing nim by such a large margin

01:35:34FromGitter<sclee15> @shodan45 yes i think so too. Crystal made huge jump for this round.

02:55:04FromGitter<honewatson> @shodan45 the set up means Jester only uses 20% of available CPUs. Neither db_postgres.nim json.nim are particularly optimised. I did find that asyncpg was generally 4x faster for me than db_postgress https://github.com/cheatfate/asyncpg

06:55:33FromGitter<honewatson> On Ubuntu it goes from around 57000 req/s to 180000 req/s with threads on
06:55:41FromGitter<honewatson> Same code
07:04:57*SenasOzys quit (Ping timeout: 240 seconds)
07:09:11Araqnow you only need a user base that performs 180K req/s

07:53:45PMunchYou figured that out now?
07:54:29FromGitter<honewatson> No Ive known it for years. Its a work computer.
07:54:47Araqhave they fixed that USB issue?
07:55:27Araqdelete files on a USB stick, it gets put into the wastebin
07:55:36Araqwhich is on the same device :-)
07:56:07Araqyou can then empty your wastebin which is for all devices
07:56:15Araqstupid.
07:56:23PMunchHaha
07:56:28*endragor joined #nim
07:56:34PMunchWell I guess that's a filesystem thing more than anything
07:57:04Araqhardly, the filesystem is unixy, it has no notion of a "wastebin"
07:57:04PMunchOn Linux I get a message saying something like "This filesystem doesn't support wastebin, do you want to permanently delete these files?"
07:57:23Araqthat's ok.
07:58:18PMunchAre there any filesystems that have a built-in support for a wastebin?
07:58:51Araqmaybe, but I've only seen it in some UI layer

11:10:54FromGitter<dom96> Don't you guys worry about those techempower benchmarks. It's just a case of putting in the work to win these benchmarks, which makes these almost entirely pointless (hence the lack of motivation to improve them from me, it's currently using Nim 0.8 or something old like that. )
11:21:31FromGitter<ChristianWitts> v0.11.2 https://github.com/TechEmpower/FrameworkBenchmarks/blob/master/toolset/setup/linux/languages/nim.sh#L5 ⏎ At least fixing that is a simple PR away

11:26:40r3d9u11Hi. I'm a novice in Nim, is there exist IDE with syntax highlighting, autocompletion and step-by-step debugging? :)
11:31:02*vlad1777d joined #nim
11:40:36sendellVScode + pluggin has highlighting and autocompletion
11:41:00sendellI think none has a visual step-by-step debugger
11:44:36r3d9u11thanks for help, here (https://github.com/nim-lang/Nim/wiki/editor-support#visual-studio-code-aka-vscode) was noted that plugin "webfreak.debug" can be used for debugging. think it's for JS target only, right?
11:46:27r3d9u11did somebody used this?

12:29:38PMunchr3d9u11, haven't tried it but the common way to debug Nim applications is to use GDB. So maybe something like this would work: https://github.com/WebFreak001/code-debug
12:30:03PMunchClarification, have tried to debug with GDB. Haven't tried using vscode for Nim or the GDB integration into vscode

13:17:23AraqPMunch, I really don't :-/

13:17:55FromGitter<andreaferretti> agreed
13:18:06*Snircle joined #nim
13:18:20Araqalehander42: er ... that is not expected
13:22:12PMunchIt's more often that I look for where a variable was set though
13:22:21*endragor joined #nim
13:22:33PMunchSo scanning lines (manually) it's easier to check the start of the lines
13:23:41PMunchI feel "if y == 5: x = 10" kinda hides what the actual side effect is

13:53:09radagast_04Is there a way to make output flush only in chunks of defined page size? For example, if a stream of characters add upto 4096 bytes, only then write() will flush?

14:05:30PMunchDon't think so

14:16:00Araqradagast_04, open takes a bufsize argument for this
14:16:27Araqbut if the streams are redirected they change to "line buffering" iirc

14:53:29FromGitter<alehander42> @Araq yeah it doesn't work
14:53:36FromGitter<alehander42> it looked like it does, oh well :D
14:54:46FromGitter<alehander42> but it works in var a = @[string "x"]
14:55:07*HoloIRCUser joined #nim
14:55:11FromGitter<alehander42> var a: seq[string] = @[]
14:55:29*endragor joined #nim
14:55:35FromGitter<alehander42> so wouldn't it be a good idea to make it work for empty arrays? otherwise now sometimes you need ^
14:55:50*miran joined #nim
14:56:47FromGitter<alehander42> you need cast or manual declaration
14:58:24*floppydh quit (Quit: WeeChat 2.0.1)
15:01:55Araqalehander42: newSeq[T](0) is the better syntax IMO, @[] is a special syntax
15:06:35FromGitter<alehander42> but then why @[string "x"] works
15:07:25Araqwhy wouldn't it?
15:07:42Araqstring "x" is just string("x"), a type conversion
15:07:49Araqin this case, a useless one
15:07:53FromGitter<alehander42> ahaa
15:08:28FromGitter<alehander42> I thought @[string "a", "b"] etc worked with a different meaning
15:08:46FromGitter<alehander42> not an accidental conversion, ok

16:05:41Araqdepends on what you mean by "compile to JS"
16:06:37FromGitter<Bennyelg> want to create bunch of functions and instead writing them on pure js I want to write them using nim
