00:17:24FromDiscord<smallgram> Welp. Suddenly it's working--so nevermind.
00:27:16FromDiscord<brainproxy> Is there an easy way to raise a key press event?↵↵It doesn't matter which one, I'm just trying to have ncurse's `getch()` to read as a result of some code of mine "pressing a key" instead of waiting for the next physical key press.
00:28:03FromDiscord<ElegantBeef> @brainproxy what do you mean "raise a key press event"
00:28:21FromDiscord<brainproxy> have the nim code I'm raising press the letter "a" or whatever
00:28:35FromDiscord<brainproxy> (edit) "raising" => "writing"

00:30:33FromDiscord<brainproxy> (edit) "https://play.nim-lang.org/#ix=3meq" => "https://play.nim-lang.org/#ix=3mer"
00:31:07FromDiscord<ElegantBeef> i still dont quite follow, you want to exit the current branch if a condition is met and go to the next loop?
00:31:19FromDiscord<ElegantBeef> if you just want to go to the next iteration you can `continue`
00:31:34FromDiscord<brainproxy> nah, just that `getch()` returns and then it will go back to the top of the loop
00:31:51FromDiscord<brainproxy> which will then end because on the other thread the Atomic[bool] `running` has already been set to `false`
00:32:00FromDiscord<brainproxy> (edit) "other" => "main"
00:33:36FromDiscord<ElegantBeef> Ah rereading it seems you're attempting to prevent the blocking behaviour?
00:33:57FromDiscord<ElegantBeef> where `getCh()` blocks until it gets a key
00:34:02FromDiscord<brainproxy> yes
00:34:17FromDiscord<brainproxy> it's fine that it blocks, just want to unblock it by simulating a keypress
00:34:22FromDiscord<brainproxy> from the main thread
00:34:59FromDiscord<ElegantBeef> It probably reads from the `stdin` so you might be able to do just do `stdin.write('\0')` to get it to tick
00:35:12FromDiscord<brainproxy> I tried writing to stdin but no joy
00:35:45FromDiscord<ElegantBeef> Ah it uses what it refers to as a `stdscr` so it might have the file handle

03:45:33FromDiscord<reilly> I can't make heads or tails of this error. https://hatebin.com/ylasqwqyhn Any ideas?
03:45:57FromDiscord<ElegantBeef> somewhere you're passing 13 in `0..6`
03:46:18FromDiscord<reilly> But the thing is, I'm not.
03:46:39FromDiscord<ElegantBeef> might be the library you're using or just an odd async bug
03:47:30FromDiscord<reilly> The bizarre thing is that I've made no significant changes between today and yesterday, yet it worked fine then.
03:49:20FromDiscord<reilly> Everything I'm doing happens in one file, and the only reference to that file in the error is just `waitFor bot.startSession()`, so it must be something outside of my direct control.
03:55:12FromDiscord<reilly> sent a code paste, see https://play.nim-lang.org/#ix=3mgf
03:55:27FromDiscord<ElegantBeef> Did you update dimscord today?
03:55:44FromDiscord<ElegantBeef> Did you change your nim version, did you change your monitor's brightness? 😛
03:56:07FromDiscord<reilly> Nothing has changed.
03:56:24FromDiscord<reilly> It might be worth mentioning that it manages to get out the "Ready to rumble!" before kicking the bucket.
03:57:00voltistWoah I haven't been on IRC for a while
03:57:08FromDiscord<ElegantBeef> Woah it's a voltist
03:57:11FromDiscord<ElegantBeef> I remember them
03:58:00voltistWhat's new?
03:58:40FromDiscord<ElegantBeef> Wonder if there is any chance this is an issue with discord somehow reilly
03:58:46FromDiscord<ElegantBeef> If that braindead example fails
03:59:07FromDiscord<ElegantBeef> I'm going to give it a whirl what version are you on?
03:59:23FromDiscord<reilly> Nim 1.4.6, Dimscord v1.2.5
03:59:35FromDiscord<reilly> I'm just glad it's not my Hypixel api that's the issue 😛

04:01:27FromDiscord<reilly> I was dreading that...
04:01:42FromDiscord<ElegantBeef> Nothing here voltist, you?
04:02:08FromDiscord<ElegantBeef> Change your nim version, maybe something got corrupted
04:02:34FromDiscord<reilly> Well I also tried running this on a raspberry pi and digitalocean droplet, both give the same problem
04:02:40FromDiscord<reilly> and both I freshly updated
04:02:50FromDiscord<ElegantBeef> Hmm
04:02:52FromDiscord<reilly> As in, I compiled Nim from source on my pi not even 30 minutes ago
04:03:18FromDiscord<ElegantBeef> All on the same network?
04:03:34FromDiscord<reilly> Not the droplet, that's off in some digitalocean datacenter somewhere
04:03:57FromDiscord<reilly> Although granted, I've only tried the braindead example on my machine
04:04:06FromDiscord<ElegantBeef> Winblows or linsux?
04:04:36FromDiscord<reilly> My machine is Windows, the droplet and pi are linux based
04:04:39voltistEh not much
04:05:40FromDiscord<reilly> git push/pulled the braindead bot onto the droplet, exactly the same thing
04:05:52FromDiscord<reilly> I'm not superstitious, but I think I may be cursed.
04:06:30FromDiscord<reilly> were you using a cacert.pem?
04:06:48FromDiscord<ElegantBeef> Well i'm on linux so probably, i did just get that error with the windows build
04:07:17FromDiscord<ElegantBeef> the pem error not the range error
04:08:33FromDiscord<ElegantBeef> Yea no crash here in wine
04:08:59FromDiscord<reilly> Tried after deleting cacert.pem on my pi, no dice
04:09:06FromDiscord<reilly> I think I might actually be going a little bit crazy
04:09:40FromDiscord<reilly> If you're willing, the repo is knaque/gexp-spy
04:09:59FromDiscord<reilly> ah, no, you probably don't have a hypixel api key 🙃
04:10:42FromDiscord<ElegantBeef> You were getting a range error in that dummy example aswell?
04:11:39FromDiscord<reilly> Yep
04:11:46FromDiscord<ElegantBeef> same 0..13?
04:12:00FromDiscord<reilly> Always `Exception message: value out of range: 13 notin 0 .. 6`
04:12:12FromDiscord<ElegantBeef> ah yea that's what i meant
04:13:04FromDiscord<reilly> https://media.discordapp.net/attachments/371759389889003532/840803529395798016/unknown.png
04:13:47FromDiscord<reilly> I just remembered that the number 13 is associated with bad luck in certain cultures, so that's ironic
04:14:30FromDiscord<ElegantBeef> those were all compiled on their hardware?
04:14:35FromDiscord<reilly> Yep
04:14:37FromDiscord<reilly> just `nimble run`
04:15:00FromDiscord<ElegantBeef> That's not the dummy though
04:15:13FromDiscord<reilly> the dummy I run with `nim c -f -r testbot.nim`
04:15:41FromDiscord<ElegantBeef> Well time to try just a normal async function to see if you get the same error
04:18:14FromDiscord<reilly> so it must be a dimscord thing
04:18:15FromDiscord<reilly> sent a code paste, see https://play.nim-lang.org/#ix=3mgm
04:18:31FromDiscord<reilly> but a dimscord thing that only seems to affect me 🙃

04:20:48FromDiscord<reilly> slightly more complicated test w/ hypixel api requests still works just fine
04:22:11*mindhunter0x quit (Ping timeout: 240 seconds)
04:22:34FromDiscord<reilly> Hey @krisppurg, you made the thing, any idea what's going on here?
04:24:06FromDiscord<reilly> tl;dr even a bot as simple as `on_ready: echo "Ready to rumble!"` crashes with this message: https://hatebin.com/ylasqwqyhn
04:24:37FromDiscord<reilly> crashes on my machine, crashes on my raspberry pi, crashes on a node in a datacenter, but doesn't crash for elegantbeef for some reason 🤔
04:24:49FromDiscord<reilly> running nim 1.4.6 and dimscord 1.2.5
04:37:23FromDiscord<Rika> Maybe discord just really doesn’t like you
04:37:45FromDiscord<ElegantBeef> Yea if it's the same token it could be related to something there not working properly
04:40:14FromDiscord<reilly> Huh, go figure, it's something to do with this particular bot.
04:40:42FromDiscord<Rika> lol probably a permission thing
04:41:11FromDiscord<reilly> If so, that's a very unhelpful crash.
04:43:09FromDiscord<reilly> Now I just have to wait for the person that actually owns the server to make sure it has the right permissions. Who knows how long that could take.
04:44:06FromDiscord<ElegantBeef> Well you can make your own bot to test and make a possible PR to dimscord to more reasonably handle the crash
04:44:30FromDiscord<reilly> Wait, it might not be a permissions thing, because compiling it with my debug flag (changes what channels it sends messages in and stuff), it still crashes
04:44:41FromDiscord<reilly> So it can't be that it doesn't have permission to send messages
04:46:07FromDiscord<Rika> There are a lot more permissions than just that though heh
04:47:11FromDiscord<reilly> When in debug mode, it should only operate in a server that I own, in which it definitely has permission to send messages.
04:47:32FromDiscord<reilly> It sends 3 messages on startup, then updates those messages every hour.
04:48:34FromDiscord<reilly> There should be no reason for it to crash - you can see for yourself, the repo is knaque/gexp-spy
04:49:40FromDiscord<reilly> So, it's definitely a problem isolated to this one particular bot...
04:50:28FromDiscord<reilly> The only real difference between this and my other main bot is that the second server it's in is actually fairly large (~3000) members
04:51:01FromDiscord<reilly> Both are also in my testing server, but for the second bot, the only other server its in only has 11 members
04:51:03FromDiscord<Rika> Does it not stack trace where it does?
04:51:04FromDiscord<Rika> Does
04:51:07FromDiscord<Rika> Dies
04:52:50FromDiscord<reilly> You can see for yourself (https://hatebin.com/ylasqwqyhn) but I don't see anything in there that makes sense in the context of `Exception message: value out of range: 13 notin 0 .. 6`
04:53:02FromDiscord<reilly> (edit) "`Exception message: value" => "'value" | "6`" => "6'"
04:53:47FromDiscord<reilly> There is some internal dimscord stuff going on in there, but again, the line it points to has nothing to do with that exact error
04:54:26FromDiscord<reilly> Since the async macro does some codegen, it could be that the line in the stack trace isn't actually right, but either way it's not very helpful
04:58:19FromDiscord<reilly> sent a code paste, see https://play.nim-lang.org/#ix=3mgp
04:59:06FromDiscord<Rika> Might be the API changed and the library isn’t updated to handle that properly
04:59:33FromDiscord<reilly> Did Discord update its api sometime between yesterday and now?
04:59:47FromDiscord<reilly> That's not sarcastic, I'm serious.
05:00:30FromDiscord<reilly> last update was April 28, 2021 according to https://discord.com/developers/docs/change-log
05:00:37FromDiscord<Rika> I don’t know, did the library get updated yesterday
05:01:23FromDiscord<reilly> The version of Dimscord I'm using (latest release) is from december 2020
05:01:37FromDiscord<reilly> So it is old, but that doesn't change that it worked yesterday
05:02:08FromDiscord<reilly> should I try #head? I don't know if that's stable.
05:02:37FromDiscord<reilly> I guess worst it could do is crash..
05:03:52FromDiscord<reilly> braindead bot now works fine
05:03:57FromDiscord<reilly> testing the big boy
05:05:45FromDiscord<reilly> So #head works, it's just bizarre that 1.2.5 worked yesterday and not now...

05:55:44FromDiscord<Rika> You aren’t awaiting the threads
05:55:58FromDiscord<Rika> So they aren’t given time to run
05:56:22FromDiscord<Rika> Remember that there is no actual parallelism here, it’s all concurrent
05:56:47FromDiscord<Rika> And it’s cooperative so you have to explicitly give time to the other threads to run
05:58:05FromDiscord<Rika> Calling a proc that returns a future means you’re scheduling that to be run, awaiting something means you’re giving the scheduler time to run everything else as well as waiting for whichever future you’re awaiting to complete

08:19:30FromDiscord<Varriount> Especially this:↵↵> This is a classic logical fallacy: it’s an appeal to authority. It doesn’t say why the syntax is better, just asserts that somebody else (C) thinks it’s better. A slight variant on the argument says that making mnemonic assembler syntax reminiscent of the syntax of higher-level languages will make the language easier to learn for people who already know higher-level languages.

13:49:16FromDiscord<dom96> I want to analyse the address that sent it
13:49:17FromDiscord<Rika> you're not gonna easily trace where it came from
13:50:03FromDiscord<dom96> It seems most of the transcations into the wallet that sent it came from Binance
13:50:12FromDiscord<dom96> so yeah, not gonna find much more about it I guess
13:50:19FromDiscord<dom96> Unless I can send a warrant to Binance 😛
13:51:43FromDiscord<mischa_u> Lol that sounds like a great way to alienate anyone who would ever want to donate to Nim
13:53:49FromDiscord<Rika> why do you want to know anyway

13:56:40FromDiscord<dom96> There is your answer

14:00:26FromDiscord<Rika> i think adding a gcsafe pragma on the proc will tell why its not gcsafe

14:31:29FromGitter<bung87> hmm doesn't like python's
14:36:06FromGitter<bung87> oh, I can do `except A,B: getCurrentException()`
14:39:26FromDiscord<retkid> Can you compile nim yo java via C
14:39:53FromDiscord<Rika> nim to java? if you have a C->java then sure
14:41:01FromDiscord<retkid> (edit) "nim" => "to"
14:41:12FromDiscord<retkid> Nim really is magic
14:42:08FromDiscord<Rika> well it might not work if the C to java translator is bad so
14:42:16FromDiscord<Rika> but that's not nim's responsibility any more

14:48:18FromDiscord<hamidb80> what happens when i compile with `-d:release` that cause 6x speed?
14:53:27FromDiscord<hamidb80> i think it removes debug information
14:53:53FromDiscord<hamidb80> but what are those "debug information"?
14:54:14FromDiscord<hamidb80> i know it contains line number
14:54:21FromDiscord<hamidb80> (edit) "i know it contains line number ... " added "for eg"
14:54:24FromDiscord<hamidb80> (edit) "eg" => "e.g."
14:54:32FromDiscord<hamidb80> (edit) "number" => "numbers"
14:55:11FromDiscord<haxscramper> it also disables some runtime checks
14:55:32FromDiscord<haxscramper> with `-d:release` you can assign to `.kind` fields for example
14:55:39FromDiscord<haxscramper> some array bound checks
14:55:58FromDiscord<zidsal> I thought array bound checks needs the danger flag?
14:56:06FromDiscord<haxscramper> IIRC `assert` also behaves differently, though I don't remenber exact details

20:22:14ForumUpdaterBotNew post on r/nim by Pcarbonn: how to modify a package, see https://reddit.com/r/nim/comments/n8mmib/how_to_modify_a_package/
20:53:31FromDiscord<ElegantBeef> @treeform dont know if you saw in the RFC, but with a bit of a modification to streams binny isnt as nearly fast by comparison https://media.discordapp.net/attachments/371759389889003532/841055301725585438/unknown.png
20:54:15FromDiscord<ElegantBeef> Still vastly slower in `--newRuntime` but that's an issue with the `of` operation, so with arc/orc it's like 4ms per tick
20:54:53FromDiscord<ElegantBeef> Yea new runtime not nearly as nice https://media.discordapp.net/attachments/371759389889003532/841055647164661770/unknown.png
20:55:16FromDiscord<treeform> I saw the RFC, i StringStream would still be slower.
20:55:25FromDiscord<treeform> But yeah that bench shows they are nearly identical.
20:55:36FromDiscord<treeform> (edit) "I saw the RFC, i ... StringStream" added "thought"
20:55:55FromDiscord<ElegantBeef> Yea, it was just spending a lot of time in the string growth, which is weird since your library does the same thing
20:56:05FromDiscord<treeform> well it was growing it not by 2
20:56:13FromDiscord<treeform> which does not amortize as well.
20:56:24FromDiscord<ElegantBeef> Did your override the setlen?
20:56:28FromDiscord<treeform> no
20:56:50FromDiscord<ElegantBeef> So then i dont see the difference in both cases a `setLen(len + size(t))` was being done
20:57:12FromDiscord<treeform> what was the fix then?
20:57:39FromDiscord<ElegantBeef> I changed the growth rate, but i could've sworn i seen the same setlen call
20:58:18FromDiscord<treeform> I think setLen grows stuff by 2
20:58:35FromDiscord<treeform> I do use nearly identical code: https://github.com/treeform/flatty/blob/master/src/flatty/binny.nim#L41
20:59:03FromDiscord<ElegantBeef> Yea it's odd, but i'll take it as a win 😄
20:59:17FromDiscord<treeform> what change did you make to StringStream?
20:59:46FromDiscord<ElegantBeef> I implemented a custom growth rate which lets you grow the string by a multiplier instead of whatever it was doing before
21:00:08FromDiscord<ElegantBeef> Here's the diff https://github.com/nim-lang/Nim/pull/17977/files
21:00:44*kenran quit (Remote host closed the connection)
21:03:07FromDiscord<ElegantBeef> It allocates roughly 30 thousand more characters with a growth rate of 2
21:03:24FromDiscord<ElegantBeef> So yea not a memory efficient optimization, just odd
21:04:41FromDiscord<ElegantBeef> You might be able to use similar logic to make a fast binny serializer, but no clue
21:09:11FromDiscord<treeform> looks complex I would just 2 and not allow chaining that
21:09:24FromDiscord<treeform> but its great that this was discovered, thank you for making the changes
21:10:41FromDiscord<ElegantBeef> Lol i just seen planetis' comment about the stream implementation and had to dig in, kinda makes me want to make a nimconf talk about benchmarking, profiling and preconceived notions of code
21:12:46FromDiscord<ElegantBeef> As much as i like benchy, it does not tell you why it's slow just if it's slow, so using it as evidence as planetis did that streams implementation is slow was just the wrong conclusion, since in 3 seconds i seen the reason it was slow was not actually a limitation of the string implementation 😄
21:12:58FromDiscord<ElegantBeef> (edit) "string" => "stream"
21:13:25FromDiscord<ElegantBeef> Plus there is the whole `lto` compilation which without just causes all external modules to look slow
21:13:30FromDiscord<treeform> Well I use vtune to look at streams
21:13:38FromDiscord<treeform> and it was saying the dynamic dispatch was slow
21:13:47FromDiscord<treeform> So I made the wrong conclusion too
21:13:51FromDiscord<treeform> but I did use more tools
21:14:03FromDiscord<ElegantBeef> Hmm
21:15:40FromDiscord<ElegantBeef> I mean if there was a cpu graph next to the claim i wouldnt have looked into it, so more just a case of the amount of evidence, seeing a post linking to a benchmark just made me ask too many questions 😛
21:18:02FromDiscord<ElegantBeef> It's a bit odd that the cause changed, now i'm curious if there is a reason for that
21:18:11FromDiscord<ElegantBeef> Though if you tested on arc/orc that'd explain it
21:18:54FromDiscord<ElegantBeef> The `of` operation on `newRuntime` is apparently very very slow

21:29:14FromDiscord<treeform> I am stuck on this perf puzzle a little bit, it appears using arrays in nim is slower then using objects.
21:30:23FromDiscord<treeform> If you want bench perf puzzles here is a big one: https://gist.github.com/treeform/326b96e48743424c1d5e4dcb17402715
21:31:13FromDiscord<treeform> Why is `a[i] = v` slower then `a.arr[i] = v` ?
21:31:33FromDiscord<treeform> Why is `a[i] = v` slower then `cast[ptr float32](cast[uint64](a.addr) + i.uint64 sizeof(float32).uint64)[] = v` ?
21:31:42FromDiscord<treeform> Makes no sense! My hair is falling out.

23:31:10FromDiscord<ElegantBeef> Ok now to ram my head into the wall of treeforms problem
23:44:05FromDiscord<ElegantBeef> @treeform found a solution to your slow problem, do less maths 😛
23:44:17FromDiscord<ElegantBeef> https://media.discordapp.net/attachments/371759389889003532/841098273112064031/unknown.png
23:44:48FromDiscord<ElegantBeef> Only actually need a single cast
23:44:59FromDiscord<treeform> Why is the vec3array slower?
23:45:08FromDiscord<ElegantBeef> It's all the same with`lto`
23:45:26FromDiscord<ElegantBeef> with the old runtime atleast
23:46:38FromDiscord<ElegantBeef> Benchmarking is hard so i can only say "i think" it's faster and not just completely removed
23:47:24FromDiscord<ElegantBeef> If you're using the assignment from other modules that's why
23:48:06FromDiscord<ElegantBeef> Atleast in my looking into it if you dont have lto and use code from other modules the code just isnt inlined or optimized outside the main module
23:48:31FromDiscord<ElegantBeef> So without `lto` you can write a faster iterator than the system provided ones
23:54:27FromDiscord<ElegantBeef> Atleast with lto and the changes i made it optimizes away the same as the `arr` implementation
23:54:37FromDiscord<ElegantBeef> So take that with a grain of salt 😄
23:57:56FromDiscord<ElegantBeef> Yea it's very bad to say anything here due to this being the output now with the changes i made to `[]=` and `set` https://media.discordapp.net/attachments/371759389889003532/841101709299679252/unknown.png
23:59:01FromDiscord<ElegantBeef> I can say though that `cast[ptr UncheckedArray[float32](a.addr)[i + 1] = v` is just nicer than the other method 😄
