| 07:07:11 | Prestige | didn't the element team absorb gitter? |
| 07:07:17 | FromDiscord | <ElegantBeef> Yep |
| 07:08:37 | FromDiscord | <JSGRANT> They really NEED to stop rebranding; Element is what... their third attempt? |
| 07:08:40 | Prestige | Hopefully element's client will get a lot better |
| 07:08:54 | Prestige | All I know is Riot -> Element |
| 07:08:59 | FromDiscord | <ElegantBeef> Isnt it only their second |
| 07:09:26 | FromDiscord | <Rika> second |
| 07:09:29 | FromDiscord | <Rika> second? |
| 07:09:30 | FromDiscord | <Rika> first |
| 07:09:33 | FromDiscord | <Rika> first rename |
| 07:09:34 | FromDiscord | <ElegantBeef> I meant second name |
| 07:09:37 | FromDiscord | <Rika> yes |
| 07:09:54 | Prestige | I dislike how generic the names are |
| 07:10:39 | FromDiscord | <JSGRANT> The reason for the rename is stupid; But legally I get it (Think riot games were waving their trademark at them) but I swear there was a name before riot |
| 07:10:46 | FromDiscord | <Rika> its the in thing apparently, prolly a boomer thing i feel; younger people would likely use more interesting names than "element" |
| 07:10:55 | FromDiscord | <JSGRANT> could be wrong; but thought it was like generic 'matrix client' or something? |
| 07:11:04 | FromDiscord | <Rika> thats worse than "element" is it not |
| 07:11:09 | Prestige | I just dislike it because it's difficult to find |
| 07:11:33 | Prestige | and not very memorable |
| 07:11:49 | FromDiscord | <ElegantBeef> I still need to continue my channelled voip implementation but havent got further than getting voip to work in there |
| 07:12:27 | FromDiscord | <JSGRANT> _tries for bed._ |
| 07:16:27 | saem | welp... looks like I can make the IC (rod query, I think) crash with an assertion error in nimsuggest... will have to debug that at some point. |
| 07:18:15 | FromGitter | <Araq> with the current default where IC is turned off? |
| 07:18:24 | saem | Yeah, that's the weird thing |
| 07:18:50 | saem | the repro is to run nimsuggest on `compiler/nim.nim` as the project, then `sug compiler/semstmts.nim:1324:34` |
| 07:19:46 | saem | now it works... wtf, what did I change. |
| 07:21:26 | FromDiscord | <carpal> yo araq |
| 07:21:30 | saem | crap, i lost my old log too. 🤦 |
| 07:23:14 | saem | whoops, I'm tired and making mistakes, the second repro step is not `sug`, it's `def` |
| 07:36:40 | saem | araq: I need to still check if it's an issue with my specific nimsuggest build (unlikely, but who knows) but I've made some notes for myself here. https://gist.github.com/saem/91b487da989bb5f47a43a9af08b08dd1 |
| 07:38:18 | saem | I'll see if I can do that tomorrow but weekdays are a gong show for me. |

| 08:55:30 | FromDiscord | <carpal> guys there's a problem |
| 08:55:40 | PMunch | Probably since no-one has to plan travel and accommodations |
| 08:55:49 | PMunch | @ElegantBeef, what do you mean? |
| 08:55:55 | FromDiscord | <carpal> in these two days I was using nim I wanted to write an object type for multi variable typing |
| 08:56:11 | FromDiscord | <ElegantBeef> The internal game window was drawn slightly closer to the left side of the frame than the right |
| 08:56:24 | FromDiscord | <carpal> but today I discovered that nim already supports object type ... 😐 |
| 08:56:24 | PMunch | Ooh :P |
| 08:56:44 | PMunch | In the browser the whole game is also a bit taller than the box it is put in.. |
| 08:56:46 | FromDiscord | <carpal> and someone merged my package request on github |
| 08:56:53 | FromDiscord | <carpal> should I delete it? |
| 08:56:58 | FromDiscord | <ElegantBeef> support object type? |
| 08:57:01 | PMunch | I can't see the bottom part of the border, and I have a black bar on the top |
| 08:57:08 | FromDiscord | <ElegantBeef> yea i fullscreen it though |
| 08:57:21 | FromDiscord | <carpal> in this moment my proj is useless |
| 08:57:23 | FromDiscord | <carpal> lol |
| 08:57:34 | FromDiscord | <ElegantBeef> What do you mean by "supports object type"? |
| 08:57:47 | FromDiscord | <carpal> var x: object = "dd" |
| 08:57:51 | FromDiscord | <carpal> (edit) ""dd"" => ""dd"↵x = 9" |
| 08:58:15 | FromDiscord | <carpal> (edit) "var x: object = "dd"↵x = 9" => "sent a code paste, see https://play.nim-lang.org/#ix=2Ngc" |
| 08:58:36 | FromDiscord | <carpal> these tests work but now the object is useless https://media.discordapp.net/attachments/371759389889003532/803187052116049930/unknown.png |
| 08:59:12 | FromDiscord | <ElegantBeef> You really should use assert or doAssert in tests 😄 |
| 08:59:13 | FromDiscord | <carpal> ah okay, but I cannot use object in structs |
| 08:59:20 | FromDiscord | <carpal> yea lol |
| 09:01:03 | FromDiscord | <carpal> ok I replaced all echos with assert expression thank you |
| 09:01:41 | FromDiscord | <ElegantBeef> Sometimes i'm incapable of reading a sentence as anything but sarcastic 😄 |

| 09:18:38 | FromDiscord | <carpal> (edit) "concrete" => "nonconcrete" |

| 09:18:48 | FromDiscord | <carpal> (edit) "non concrete" => "non-concrete" |
| 09:19:41 | FromDiscord | <carpal> this happens only with vars |
| 09:21:50 | FromDiscord | <lqdev> you can't |
| 09:21:55 | FromDiscord | <lqdev> `object` is a type class, not a type |
| 09:22:01 | FromDiscord | <Clyybber> object is a type class. it doesnt exist at runtime |

| 11:14:13 | FromDiscord | <konsumlamm> "yeah, cannot be bothered to install irc clients on my newer machines" |
| 11:14:55 | FromDiscord | <mratsim> For over a year, gitter gave me a black screen on Linux so I stopped using it. |
| 11:15:20 | FromDiscord | <mratsim> also they were bought (?) by Matrix so I assume it will see no updates in the foreseeable future |
| 11:15:42 | narimiran | @konsumlamm merged |
| 11:28:51 | FromDiscord | <Rika> I think he means to check the nim vm to learn from it for your vm |
| 11:29:20 | FromDiscord | <carpal> ah |

| 11:30:03 | FromDiscord | <Rika> It does? It’s what processes macros |

| 11:35:34 | FromDiscord | <carpal> better graphics, functionalities, replies |
| 11:35:50 | FromDiscord | <Rika> Having a small core is nice for a language but I feel like it doesn’t work too well for a package manager |
| 11:36:53 | FromDiscord | <Rika> If someone already has a gitter account why would they move to discord, same for each combination of account driven websites in the same category |
| 11:38:30 | FromDiscord | <Rika> Maybe I should actually finally try nimph |

| 11:49:59 | FromDiscord | <Rika> The moving of services? |
| 11:50:11 | krux02 | Discord has many other channels as well. If you use gitter only for things that you also can you discord for, you might drop gitter |
| 11:50:19 | FromDiscord | <Rika> Yeah |
| 11:50:22 | FromDiscord | <Rika> Makes sense |

| 11:50:55 | FromDiscord | <Rika> I’m just trying to give an alternate view though if you can tell I’ve likely failed |
| 11:51:07 | krux02 | It is just owned partially by Tencent. |
| 11:52:10 | krux02 | There are companies out there that try to conquer and control the internet for reasons mostly unknown. |
| 11:52:15 | krux02 | Tencent is one of them. |
| 11:52:23 | FromDiscord | <Rika> Basically anything gamer nowadays is partly owned by ten cent |
| 11:52:26 | FromDiscord | <mratsim> Tencent basically owns all game companies of the world |
| 11:52:45 | krux02 | well that is not true. |
| 11:52:58 | krux02 | I mostly buy indie games. |
| 11:53:06 | FromDiscord | <mratsim> all successful game companies of the world |
| 11:53:11 | FromDiscord | <Rika> Of |
| 11:53:13 | FromDiscord | <Rika> Oof |
| 11:53:28 | krux02 | If your game runs on Linux, it is probably not owned by Tencent. |
| 11:53:37 | FromDiscord | <mratsim> I play Path of Exile for example, NZ game company, indie, it grew it grew, and now Tencent owns XX% |
| 11:53:59 | krux02 | I don't play Free to Play, I dislike the business model. |
| 11:54:20 | FromDiscord | <Rika> Wangan midnight runs on Linux (arcade machine is Linux based) and I am guessing Tencent has partial ownership of Bandai Namco |
| 11:54:33 | FromDiscord | <Rika> 😛 |
| 11:54:45 | krux02 | I think the business model of free to play games is mostly to the disadvantage of the customer. Therefore I avoid it. |
| 11:55:14 | krux02 | does it have a Linux release? |
| 11:55:48 | FromDiscord | <mratsim> PoE is free to play and you only pay for skins |
| 11:55:55 | FromDiscord | <mratsim> it's not pay-to-win |
| 11:55:56 | FromDiscord | <Rika> No, I was just making a joke of a response |
| 11:56:06 | krux02 | ok |
| 11:56:25 | krux02 | I also dislike "pay for skins" "pay for dances" "pay for cosmetics" |
| 11:56:41 | krux02 | nothing of that is acceptable for me. |
| 11:57:02 | FromDiscord | <mratsim> Why? |
| 11:57:08 | FromDiscord | <Rika> How do you expect developers to earn money then? |
| 11:57:33 | krux02 | The business model is still to make me invest as much time as possible into the game so that I eventually care about those cosmetics. |
| 11:57:34 | FromDiscord | <Rika> It makes it seem like anything that involves monetisation directly or indirectly is unacceptable to you |
| 11:57:46 | krux02 | Effectively a business model that tries to maximize my time wasted. |
| 11:57:54 | FromDiscord | <Rika> Well, that’s the intent of any game is it not |
| 11:57:54 | krux02 | I don't want to buy into that. |
| 11:58:00 | krux02 | no it's nto |
| 11:58:08 | FromDiscord | <Rika> If you think you’re wasting time playing games then don’t ever play one |
| 11:58:14 | FromDiscord | <mratsim> Game != time wasted. |
| 11:58:25 | krux02 | If you pay for a game, then the game owner doesn't care how long you play the game. |
| 11:59:00 | krux02 | Therefore there is no business that requires to streach the playtime as much as possible. |
| 11:59:04 | FromDiscord | <Rika> That’s the thing, they made the game so you’re engaged in the game aka don’t want to stop, is it not like that for open world games or so? |
| 11:59:35 | FromDiscord | <mratsim> stretching the play time is your own decision |
| 11:59:43 | FromDiscord | <mratsim> Why would i play a game that is not engaging. |
| 12:00:18 | FromDiscord | <mratsim> For example, go is also free-to-play and you can pay for skins (luxury boards). I wouldn't play it if it was not engaging as well. |
| 12:00:24 | FromDiscord | <Rika> The issue in this argument is that the concept of wasted time is subjective, is it not |
| 12:00:48 | FromDiscord | <mratsim> The issue is assuming game dev can control how your spend your time. |
| 12:00:58 | krux02 | all F2P games are essentially endless grinds into absurdity. |
| 12:01:09 | FromDiscord | <Rika> I’m here in the arcade right now, probably have sunk half a grand in this arcade game over two months, I don’t think I wasted time at all |
| 12:01:13 | krux02 | Same btw with MMORPGs that you pay per month |
| 12:01:39 | FromDiscord | <Rika> Only thing game devs can do is influence |
| 12:01:39 | krux02 | no go is not free to play, Go is entirely free |
| 12:01:46 | krux02 | it is public domain. |
| 12:01:54 | krux02 | there is nobody who own go. |
| 12:02:14 | krux02 | and everybody is allowed to modify the game and improve it. |
| 12:02:23 | krux02 | That is by the way how chess and go evolved. |
| 12:02:37 | FromDiscord | <Rika> Changing go would be making a different game |
| 12:02:39 | FromDiscord | <mratsim> it's also an endless grinds |
| 12:02:57 | FromDiscord | <Rika> Unless it becomes universally acceptable |
| 12:03:35 | krux02 | Well I can't change your opinion. I don't consider go an endless grind, because winning the game doesn't give you anything except winning the game. |
| 12:03:44 | FromDiscord | <Rika> You two have fun, I’ll be playing now |
| 12:03:51 | krux02 | Another story is tournament chess with badges and stuff |
| 12:03:56 | krux02 | that is an endless grind again. |
| 12:03:59 | FromDiscord | <Rika> Winning the game can give skill can it not |
| 12:04:15 | FromDiscord | <Rika> The grind can be endlessly grinding to become better at the game |
| 12:04:28 | krux02 | Well I don't play chess either. |
| 12:05:02 | FromDiscord | <mratsim> you don't need to win to get better |
| 12:05:18 | krux02 | Board games also never try to lure you into playing the game with special weekend offers if you actually wanted to quit playing. |
| 12:05:30 | FromDiscord | <mratsim> The most significant thing Go and I assume chess can teach you is patience |
| 12:05:47 | FromDiscord | <mratsim> and also humility, because you lose half your games. |
| 12:05:54 | krux02 | anyway, I don't want to spam this chat again with game related discussions. |
| 12:06:08 | FromGitter | <Araq> mratsim, I'm "about" to add a condition variable to your simple channel implementation |
| 12:06:28 | FromGitter | <Araq> so that `send` blocks when the queue is full |
| 12:06:45 | FromGitter | <Araq> anything I need to watch out for when I attempt to do this? |
| 12:07:41 | FromDiscord | <mratsim> I think having a standard channel interface is best, because they come in all kind of flavors |
| 12:08:20 | FromDiscord | <mratsim> We can have a ChannelConcept that just implements trySend and tryRecv, and a BlockingChannelConcept that "inherits" from is and has `send`, `recv` |
| 12:08:48 | FromDiscord | <mratsim> just make sure you have a while loop around your CV to handle spurious wakeups |
| 12:09:36 | FromDiscord | <mratsim> and if you deadlock on Linux, well you know that glibc CV may list a cv.signal() |
| 12:10:03 | FromGitter | <Araq> "may list", what do you mean? I know about spurious wakeups |
| 12:10:12 | FromDiscord | <mratsim> may lose |
| 12:10:25 | FromDiscord | <mratsim> sorry, somehow my thoughts/writing is all jumbled up today |
| 12:11:08 | FromGitter | <Araq> wait what? it may lose a `signal` call? |
| 12:11:29 | FromGitter | <Araq> what am I supposed to do then... |
| 12:12:55 | FromDiscord | <mratsim> This bug: https://github.com/mratsim/weave/issues/56 |
| 12:12:56 | disbot | ➥ [Glibc] Condition variable lost wakeups |
| 12:13:33 | * | asdflkj joined #nim |
| 12:13:58 | FromDiscord | <mratsim> do it assuming there is no lost `signal`.↵One day I will reimplement, locks, CV, Semaphores on top of raw Futex. |
| 12:14:12 | FromDiscord | <mratsim> (and formally verified) |
| 12:15:14 | FromDiscord | <mratsim> seems like Intel used timedwait to workaround deadlocks: https://community.intel.com/t5/Intel-Fortran-Compiler/OpenMP-deadlocks-for-long-running-jobs/td-p/1117723 |
| 12:15:24 | FromDiscord | <mratsim> due to the condvar bug. |
| 12:16:02 | FromDiscord | <konsumlamm> a very general question, i know, perhaps i should make a thread on the forums: what's the planned future for parallelism in Nim? |
| 12:16:13 | FromGitter | <Araq> weave |
| 12:16:23 | FromDiscord | <mratsim> for compute bound workload there is Weave |
| 12:16:40 | FromDiscord | <konsumlamm> are there any plans to make threadpool stable? |
| 12:16:45 | FromDiscord | <mratsim> for IO bound workload there isnothing yet, though i plan to do weave IO |
| 12:17:20 | FromDiscord | <mratsim> for a basic threadpool I will need to write one anyway for high performance cryptography (Weave is likely too complex to audit). |
| 12:17:35 | FromDiscord | <konsumlamm> (threadpool as in the stdlib module) |
| 12:17:43 | FromDiscord | <mratsim> you can use yglukhov lib for threadpool: https://github.com/yglukhov/threadpools |
| 12:18:12 | FromDiscord | <konsumlamm> weave looks pretty cool though |
| 12:18:25 | FromDiscord | <mratsim> for interop between IO and CPU, CPS (continuation passing style) is the plan |
| 12:18:41 | FromDiscord | <mratsim> why do we need different scheduler for IO and Compute is explained here: https://github.com/weavers-guild/weave-io/blob/master/blog/multithreading_flavors.md |
| 12:18:54 | * | gator joined #nim |
| 12:19:09 | FromDiscord | <konsumlamm> i'm wondering, are there any plans to change the stdlub situation with regards to parallelism? will threadpool (with spawn & parallel) just always stay unstable? |
| 12:19:30 | FromDiscord | <mratsim> It's mostly a time problem. |
| 12:19:45 | FromGitter | <Araq> konsumlamm: I don't know yet. |
| 12:20:23 | FromDiscord | <mratsim> ideally we have a common type or at least concept for tasks and awaitables. |
| 12:21:00 | FromDiscord | <mratsim> and also a way to pack locals into closures that is flexible for memory management. |
| 12:21:25 | FromDiscord | <mratsim> so that Weave, threadpools, async are all interoperable. |
| 12:21:31 | FromGitter | <Araq> konsumlamm: one likely outcome: threadpool's basic `spawn` feature remains and the rest will be thrown away |
| 12:21:32 | FromDiscord | <mratsim> and composable. |
| 12:21:42 | FromDiscord | <konsumlamm> btw, speaking of spawn, is there any particular reason you chose to make it only accept proc calls, instead of just passing a proc? maybe to mimic go? |
| 12:22:01 | FromDiscord | <konsumlamm> (edit) i'm wondering, are there any plans to change the stdlib situation with regards to parallelism? will threadpool (with spawn & parallel) just always stay unstable? |
| 12:22:04 | FromDiscord | <mratsim> you need a proc + parameters anyway |
| 12:22:05 | FromGitter | <Araq> you need the proc call arguments for the marshalling |
| 12:22:31 | gator | where does cps fit into all this plan? sorry new to nim, don't know much. |
| 12:22:38 | FromDiscord | <mratsim> Also this is how parallelism has been done since 1995 (the Cilk paper) |
| 12:22:46 | FromDiscord | <mratsim> fork-join parallelism |
| 12:22:46 | FromGitter | <Araq> konsumlamm: they won't stay "unstable" but most APIs in there are flawed beyond repair |
| 12:22:48 | FromDiscord | <konsumlamm> sounds like a good idea |
| 12:23:40 | FromDiscord | <konsumlamm> @Araq does that mean they'll be deprecated and removed eventually? |
| 12:23:58 | FromGitter | <Araq> yeah |
| 12:24:55 | FromGitter | <Araq> the APIs are bad and the implementation predates Nim's move semantics so there is not much to keep |
| 12:25:19 | FromGitter | <Araq> however, the `spawn` thing is the right idea and remains |
| 12:25:25 | FromDiscord | <mratsim> I prefer spawn/sync to spawn/`^` btw |
| 12:26:02 | FromGitter | <Araq> *shrug* we can rename it to `sync`, I won't lose sleep over that |
| 12:26:11 | FromDiscord | <mratsim> 😉 |
| 12:27:41 | FromDiscord | <mratsim> also @konsumlamm createThread works very well if you just want to run threads as service. |
| 12:28:08 | FromDiscord | <mratsim> it deals nicely with the OS differences. |
| 12:28:19 | * | sagax joined #nim |
| 12:28:27 | FromGitter | <Araq> depending on your needs, threadpool also "works", the problem is who wants to debug it when it doesn't |
| 12:28:43 | FromGitter | <Araq> not me. ;-) |
| 12:29:12 | * | gator quit (Quit: Connection closed) |
| 12:30:34 | FromGitter | <Araq> bbl |
| 12:30:39 | FromDiscord | <konsumlamm> you mean the stdlib createThread proc? that uses OS threads though, right? |
| 12:31:10 | FromDiscord | <mratsim> yes |
| 12:31:31 | FromDiscord | <konsumlamm> also, i dislike that you have to pass a var instead of just returning it, but thats just a nit |
| 12:32:29 | FromDiscord | <mratsim> that's what the OS provides at a low-level. People can write a version with out parameter. |
| 12:34:00 | FromDiscord | <konsumlamm> sure, but wouldnt it be nicer if the stdlib would just provide it? |
| 12:38:20 | FromDiscord | <mratsim> PRs are open. |
| 12:42:27 | FromDiscord | <konsumlamm> i can try xd |
| 12:42:50 | FromDiscord | <konsumlamm> there are also still enough modules to fix documentation for |

| 13:27:20 | FromDiscord | <konsumlamm> @mratsim what's the difference between weave-io and asyncdispatch? |
| 13:32:31 | FromDiscord | <flywind> How can I use `importc` to import c function in MacOSX? |
| 13:32:40 | FromDiscord | <flywind> for example |
| 13:32:43 | FromDiscord | <flywind> sent a code paste, see https://play.nim-lang.org/#ix=2Nhr |
| 13:32:47 | FromDiscord | <flywind> https://git.privacyone.io/useful/macos-sdk/-/blob/a3892fa99785a8327cefa8d3a6b8ff449ab606e9/MacOSX10.13.sdk/usr/include/sys/random.h |
| 13:33:43 | FromDiscord | <haxscramper> I think that is correct `importc` for a given function |
| 13:33:59 | FromDiscord | <haxscramper> Can you show the error? |
| 13:34:19 | FromDiscord | <Clyybber> @konsumlamm Do you know whats the reasoning for wrapping the dump in an if false? |
| 13:34:38 | FromDiscord | <konsumlamm> so that theres no IO |
| 13:34:44 | FromDiscord | <flywind> sent a code paste, see https://play.nim-lang.org/#ix=2Nhu |
| 13:34:47 | FromDiscord | <konsumlamm> when running the tests |
| 13:34:58 | FromDiscord | <flywind> and https://dev.azure.com/nim-lang/255dfe86-e590-40bb-a8a2-3c0295ebdeb1/_apis/build/builds/12454/logs/104 |
| 13:35:11 | FromDiscord | <Clyybber> @konsumlamm But our tests can deal with that just fine |
| 13:35:34 | FromDiscord | <Clyybber> And a example that outputs something is better than a dead example |
| 13:35:52 | FromDiscord | <konsumlamm> ¯\_(ツ)_/¯ |
| 13:36:16 | FromDiscord | <konsumlamm> ask @flywind |
| 13:37:36 | FromDiscord | <flywind> that's noisy in doc tests, you could test them with testament. |
| 13:37:59 | FromDiscord | <Clyybber> then doc tests should be fixed to swallow output |
| 13:38:23 | FromDiscord | <Clyybber> if false is just unneccessary convolution, and doesn't read particularily well |
| 13:38:49 | FromDiscord | <konsumlamm> speaking of, there is no test for `dump`... |
| 13:39:15 | FromDiscord | <flywind> I would prefer code-blocks in this situation. |
| 13:40:04 | FromDiscord | <Clyybber> why? |
| 13:40:04 | FromDiscord | <haxscramper> I'm not entirely sure, but to me it looks like the issue is unrelated to your proc wrapper (at least not directly) |
| 13:40:06 | FromDiscord | <Clyybber> theres no reason |
| 13:40:59 | FromDiscord | <haxscramper> My guess is that it is somehow broke C macro somewhere up translation unit, and not you are getting unrelated errors down the line |
| 13:41:28 | FromDiscord | <Clyybber> @flywind Our runnableExamples should really not be restricted to not doing IO |
| 13:41:40 | FromDiscord | <haxscramper> But for C function declared as `int getentropy(void buffer, size_t size);`, nim wrapper `proc getentropy(p: pointer, size: csize_t): cint {.importc: "getentropy", header: "<sys/random.h>".}` is correct one AFAIC |
| 13:42:02 | FromDiscord | <flywind> I see thanks |
| 13:42:40 | FromDiscord | <Clyybber> of course they shouldn't do actual file IO |
| 13:42:46 | FromDiscord | <Clyybber> but echo and the like is fine |
| 13:44:31 | * | clyybber joined #nim |
| 13:46:52 | FromDiscord | <konsumlamm> @Clyybber now i need to make another PR to fix the examples :p |
| 13:47:01 | * | clyybber quit (Client Quit) |
| 13:47:11 | FromDiscord | <Clyybber> oh why? |
| 13:47:38 | FromDiscord | <konsumlamm> the second example for `capture` should be changed or removed, since it's behaving the same without `capture` |
| 13:47:55 | FromDiscord | <Clyybber> ah, I see. I didn't grok that you wanted to do it in that pr too :D |
| 13:48:37 | FromDiscord | <konsumlamm> though i'm thinking about just dropping that example, since the issue doesn't really occur when using `mapIt` and the like... |
| 13:54:22 | FromDiscord | <konsumlamm> btw, i'd love to see https://github.com/nim-lang/Nim/pull/16634 getting merged |
| 13:54:22 | disbot | ➥ Make small text changes in the docs |

| 14:36:45 | FromDiscord | <mratsim> well fibonacci 30 is 2^30 operations |
| 14:36:49 | FromDiscord | <carpal> I think I'll use a classic pointer, so I've to leave the dynamic typing |

| 14:56:04 | PMunch | Yes |
| 14:56:09 | PMunch | All talks are pre-recorded |
| 14:56:15 | FromGitter | <Araq> (what a question...) |
| 14:56:45 | PMunch | With a live QA session after that, and a "hallway discussion" that's live as well, but will overlap with the next talk |
| 14:57:49 | PMunch | So my talk for example is 27 minutes, the slot is 30 minutes, so there will be a 3 minute QA and then people can join me for a hallway discussion while the next talk starts (well mine is the last for the day, but as an example). |
| 14:58:01 | PMunch | Would be wild if it was not virtual |

| 15:07:43 | PMunch | @Araq, any particular thing you wanted me to mention? |
| 15:08:25 | FromGitter | <Araq> no, I would add my unqualified remarks and questions to make the talk more entertaining |
| 15:08:46 | PMunch | haxscramper, ah here it is: https://github.com/PMunch/libbuilder |
| 15:08:57 | FromGitter | <Araq> not that your talk isn't entertaining, you're a superb speaker |

| 15:09:36 | FromGitter | <Araq> yeah, maybe |
| 15:10:08 | FromGitter | <Araq> mratsim, "consistency is an illusion" |
| 15:11:21 | FromGitter | <Araq> hundreds of natural languages exist, occasionally changing the grammar for more consistency. They evolve for thousands of years. They are all now "consistent" by now... right? no? how come... |
| 15:13:15 | FromDiscord | <lqdev> natural languages ≠ computer languages though |

| 15:55:02 | FromDiscord | <lqdev> and `import nimprof` |
| 15:55:11 | FromDiscord | <lqdev> you need `--stackTrace:on` for this btw |
| 15:55:21 | PMunch | I guess I could have check in the callback which would just make it do nothing.. |
| 15:55:46 | FromDiscord | <carpal> nothing to add in the code? |
| 15:55:51 | FromDiscord | <lqdev> no |

| 16:00:15 | PMunch | Hmm, I can clear the callback.. |
| 16:01:18 | PMunch | So I can have a global "timer" variable which is a Future[void] from sleepAsync. Then I can clearCallback if the variable is set and create a new sleepAsync and set a callback on that |
| 16:02:29 | PMunch | Oh, I can even call `complete` on it |
| 16:06:55 | FromDiscord | <lqdev> @carpal read that file and check which calls were the "hot spots" |
| 16:07:03 | FromDiscord | <lqdev> aka which procs were called the most |
| 16:07:05 | FromDiscord | <lqdev> and took the most time |
| 16:07:28 | FromDiscord | <carpal> ok so it is a proc call trace? |

| 16:08:35 | FromDiscord | <lqdev> yeah, it shows you how much time it spent in each proc |
| 16:08:49 | FromDiscord | <lqdev> seems like there's a lot of `genericAssignAux`es |
| 16:09:00 | FromDiscord | <lqdev> quite a bit of time was spent in `pop` |

| 16:11:43 | FromDiscord | <carpal> btw I can't find the problem in this file |
| 16:17:01 | FromGitter | <Araq> `genericAssignAux` is when you don't use --gc:orc :P |

| 16:41:06 | FromDiscord | <carpal> should better diable them? |
| 16:41:07 | FromDiscord | <mratsim> I have nightmares about genericAssignAux |
| 16:41:09 | FromDiscord | <carpal> (edit) "diable" => "disable" |
| 16:41:29 | FromDiscord | <mratsim> hunting them in Arraymancer was a whack-a-mole in 2017 |
| 16:42:07 | FromDiscord | <lqdev> is it GC-safe to cast a `ref T` to a `ref RootObj`? or will the refcount get desynced |
| 16:42:18 | FromDiscord | <lqdev> talking mostly about ARC here because default GC deems to work |
| 16:43:29 | FromDiscord | <mratsim> ref RootObj is OK I think, ref Something of RootObj is not unless that Something is tagged {.pure.} and so does not have the additional RTTI field |
| 16:43:46 | FromDiscord | <mratsim> here be dragons |
| 16:44:04 | FromDiscord | <mratsim> actually RootObj likely has a RTTI field as well so probably not |
| 16:47:17 | haxscramper | I couldn't find any discussion about this, but why does nim tooling uses colon for key-value pairs? Like `--cc:tcc` instead of `--cc=tcc` |
| 16:47:55 | haxscramper | I think I've seen it mentioned __somewhere__, but can't find it right now |
| 16:48:16 | haxscramper | s/__/_/g |
| 16:49:05 | haxscramper | And almost none other CLI tool (that I know of) has this convention |
| 16:52:08 | FromDiscord | <lqdev> it supports both syntaxes actually |
| 16:52:37 | FromDiscord | <lqdev> my guess is that it's a mix of windows and unix conventions, on windows you'd do `/cc:tcc` |
| 16:53:37 | haxscramper | Nice, I didn't know it supports both. Didn't know about windows conventions though. Just thought there mighe be some other reason |

| 18:42:45 | disruptek | then it's not an array. |
| 18:42:55 | Oddmonger | am i doom to use seq ? |
| 18:43:03 | disruptek | only if you want variable-length arrays. |
| 18:43:22 | Oddmonger | no, it would be a fixed length buffer |
| 18:43:26 | disruptek | use a ref. |

| 18:45:52 | disruptek | no. |
| 18:46:05 | disruptek | suicide humor. |
| 18:47:17 | Oddmonger | it would be annoying to cannot use void as a pointer, anyway |
| 18:47:21 | Oddmonger | pooor void |
| 18:47:28 | FromGitter | <Araq> disruptek: little reminder to watch your words |

| 18:48:37 | disruptek | sorry, i'll be less f-ing toxic. |
| 18:49:48 | disruptek | Oddmonger: why don't you want to use a seq? |
| 18:50:06 | Oddmonger | isn't it slower than a array for accessing ? |
| 18:50:20 | * | disruptek sighs. |
| 18:50:22 | FromGitter | <Araq> it's one memory read either way |
| 18:50:33 | disruptek | you are worried that your application will be too slow if you use a seq? |
| 18:50:36 | Oddmonger | yes, premature optimization, i know i know |
| 18:50:41 | disruptek | why don't you benchmark it? |
| 18:50:53 | Oddmonger | it was curiosity, too |
| 18:51:09 | disruptek | i'm curious why you wouldn't use the tools that were provided to you at great expense. |
| 18:51:35 | disruptek | i'm starting to really be frustrated with this mentality i see in the community. |
| 18:51:36 | Oddmonger | when i know the size of an array at construction, why would i use varying size container ? |
| 18:51:51 | FromGitter | <Araq> because hardware works this way |
| 18:52:27 | disruptek | use whatever you want. but don't sacrifice abstraction in pursuit of performance you don't need. |
| 18:52:32 | disruptek | abstraction is much more valuable. |
| 18:52:58 | Oddmonger | it was kind of self doc too |
| 18:53:03 | ForumUpdaterBot | New thread by Chris_st: Puzzling error (warning?) messages, see https://forum.nim-lang.org/t/7429 |
| 18:53:40 | disruptek | i am fine with arrays. i use them, too. just, y'know, take my point. |
| 18:53:50 | FromGitter | <Araq> "self doc" is a fine argument |
| 18:54:13 | FromGitter | <Araq> but still, learn the implementations, don't "outsmart" them with your ignorance |
| 18:54:34 | Oddmonger | no joke, it's for storing a map : the map cannot grow, so it should be an array |
| 18:54:44 | disruptek | sure. |
| 18:54:45 | Oddmonger | for the moment , i'm using seq anyway |
| 18:55:47 | FromGitter | <Araq> feel free to write a `StaticSeq` container that lacks the `add` operation |
| 18:57:14 | FromGitter | <Araq> but don't expect differences, a read from memory is a read from memory and `seq` has no additional indirection. |
| 18:57:42 | Oddmonger | ok, so i keep the seq in my object |
| 18:58:15 | Oddmonger | thank you for explaining Araq && disruptek |

| 22:12:52 | Prestige | that way is good but you'll want ^1 not ^0 |
| 22:13:39 | Prestige | and if by first index you mean index 1 (which is the second index) |
| 22:14:03 | Prestige | https://play.nim-lang.org/#ix=2Nk1 |
| 22:14:32 | zidsal | ya I meant the second index. I thought 61 gave you the penultimate item not the final item? i.e #[1,2,3,4][1,^1] would return 2,3 |
| 22:14:54 | zidsal | clearly Ia m wrong from the example you linked me :p |
| 22:14:58 | Prestige | ^1 gives you the length of the seq - 1 |
