00:04:59FromDiscord<Chronos [She/Her]> Huh?
00:05:10FromDiscord<Chronos [She/Her]> That is the first thing I see lol
00:05:40FromDiscord<Elegantbeef> Huh?
00:08:29FromDiscord<Chronos [She/Her]> Simd accelerated string finding
00:09:01FromDiscord<Chronos [She/Her]> What usecases is SIMD useful for anyway?
00:09:17FromDiscord<Elegantbeef> Speeding up any operation that you're doing that simd can do 😄
00:09:30FromDiscord<Elegantbeef> It's a collection of hardware extensions so there is no 1 answer
00:10:14FromDiscord<Elegantbeef> Many of them are aimed at speeding up floating point calculations
00:11:42FromDiscord<Chronos [She/Her]> Ah so specifically working with floats as a whole?
00:11:52FromDiscord<Elegantbeef> I mean that's not the whole purpose
00:12:02FromDiscord<Elegantbeef> There are simd extensions for a variety of operations
00:12:22FromDiscord<Elegantbeef> Using simd for string find isnt actually daft and is a mild way of speeding up finding on a string
00:13:44termersimd means Single Instruction Multiple Data
00:13:58FromDiscord<Elegantbeef> https://www.officedaytime.com/simd512e/
00:13:58termerIf there's a SIMD instruction that works with the data you want to process to do what you want, use it
00:14:31FromDiscord<Chronos [She/Her]> Oh huh
00:14:54FromDiscord<Chronos [She/Her]> So then an example of one way it could be used is game dev for handling physics for example?
00:15:20FromDiscord<Elegantbeef> If you can find a way to use simd there, sure
00:15:31termerI have no examples
00:15:36FromDiscord<Chronos [She/Her]> Neat
00:15:38termerbut you can probably find them
00:15:43FromDiscord<Chronos [She/Her]> Fair
00:15:45FromDiscord<Elegantbeef> The thing with simd operations is they're very very specific with a purposeful use case
00:15:53FromDiscord<Chronos [She/Her]> Makes sense
00:17:16FromDiscord<Elegantbeef> The premise is that the operation on the large list that you load/unload from is faster than doing it independantly
00:17:29FromDiscord<Elegantbeef> So it's not like you can just wildly throw simd at problems and it turns out faster
00:26:00FromDiscord<Chronos [She/Her]> Ah
00:26:01FromDiscord<Andreas> In reply to @Elegantbeef "So it's not like": exactly, and thats why esp. this talk demonstrates the applied-usage of SIMD - in contrast to the more theoretic-lectures i've found earlier. String-finds and such, that you can find in SIMDJson. My guy sorts things in registers 🙂
00:26:15FromDiscord<Chronos [She/Her]> SIMDJson-
00:29:27FromDiscord<that_dude.> Can someone please help me with concepts? https://play.nim-lang.org/#ix=4E7R Is there anything wrong with this code, as in why it wouldn't compile? I'm getting a type mismatch for `C.ready()`, but not for `C.other()` Is this another naming issue where for whatever reason I can't use the proc name ready?
00:30:09FromDiscord<Elegantbeef> https://play.nim-lang.org/#ix=4E7T
00:30:12FromDiscord<Elegantbeef> As always a mixin issue
00:30:31FromDiscord<Elegantbeef> https://www.jasonbeetham.com/writeups/codereuse.html I didnt link this now I realise
00:31:32FromDiscord<that_dude.> I thought those are already know though?
00:31:52FromDiscord<Elegantbeef> `mixin` forces the compiler to look at both declaration and instantiation
00:31:53FromDiscord<heysokam> how do you define an array of 4 elements, where 3 of them are empty?↵not seq, fixed sized array 🤔
00:32:06FromDiscord<Elegantbeef> also do not do `Type[T: Bleh] = seq[T]` that makes no sense
00:32:25FromDiscord<that_dude.> Because we know that `EventContainer` must hold a `ValidEvent` which because it's concepts says so
00:32:27FromDiscord<Elegantbeef> `[default T, default T, default T, bleh]`
00:32:40FromDiscord<Elegantbeef> Sure but `seq[T]` is an alias not a distinct type
00:32:43FromDiscord<that_dude.> That was probably a remnant of me trying to figure out what I was having issues with
00:32:46FromDiscord<heysokam> In reply to @Elegantbeef "`[default T, default T,": isnt' `default cstring` the same as saying `""`?
00:32:57FromDiscord<heysokam> i need them to be truly empty, not ""
00:33:11FromDiscord<Elegantbeef> So i can just pass an `seq[int]` in
00:33:11FromDiscord<Elegantbeef> Yes you didnt say it was a cstring
00:33:11FromDiscord<Elegantbeef> nil if it's a cstring
00:33:24FromDiscord<Elegantbeef> default cstring is actually `nil`
00:33:27FromDiscord<heysokam> oh
00:36:27termercstring is a pointer
00:36:32FromDiscord<Elegantbeef> Ah actually it seems that a alias does not lose it's constraint
00:36:39FromDiscord<Elegantbeef> So I guess that's fine
00:37:07FromDiscord<Elegantbeef> Look at this guy writes a string library then thinks he's an authority on the matter! 😛
00:38:31FromDiscord<heysokam> sent a code paste, see https://play.nim-lang.org/#ix=4E7U
00:38:42FromDiscord<Elegantbeef> `cstring(nil), nil, nil, nil]`
00:38:53FromDiscord<Elegantbeef> As long as the first one is typed the others will fall in place
00:39:25FromDiscord<Elegantbeef> also not using `cstring"..."` shame on you
00:39:54FromDiscord<heysokam> i can't, because vulkan crashes
00:39:57termerI know everything about strings now, that's simply the case
00:39:59FromDiscord<Elegantbeef> What
00:40:06termerI've become an authority
00:40:07termersimple as
00:40:26termerPointers? Buffers? Null-termination? I've got it all
00:40:43FromDiscord<heysokam> In reply to @Elegantbeef "What": empty array, failed if not typed. string array? needed to be cstring. array with `[""]`... validation error and crashed

00:41:20FromDiscord<heysokam> well an error i got that didn't understand
00:41:31FromDiscord<heysokam> i just had to hardcode the size like that and then it worked
00:41:41FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4E7W
00:41:45FromDiscord<heysokam> k
00:41:49FromDiscord<Elegantbeef> The first parameter of the array has to be typed
00:41:55FromDiscord<Elegantbeef> Thats how Nim's array literals work
00:42:02FromDiscord<Elegantbeef> If the first is typed the rest are inferred

00:42:21FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4E7X
00:44:00FromDiscord<heysokam> how do `array[0..Limit, Type]` arrays work?
00:44:23FromDiscord<Elegantbeef> The same as `array[Limit, T]` cause that's what they compile to
00:44:50FromDiscord<Elegantbeef> Arrays allow a range type as the first parameter, Nim implicitly converts arrays to range indexed
00:45:05FromDiscord<Elegantbeef> So `array[0..3, cstring] is array[4, cstring]`
00:45:20FromDiscord<Elegantbeef> but `array[-1..2, cstring] isnot array[4, cstring]`
00:52:28FromDiscord<heysokam> ic
00:52:57FromDiscord<heysokam> can you do `var arr :array[4, cstring] = []`?
00:53:15FromDiscord<heysokam> basically, that's what i would ideally need 🤔
00:54:12FromDiscord<that_dude.> Thanks for both the link and the help Beef, but I'm still wondering why `other` worked but `ready` didn't. Is this a compiler bug that I should report?
00:54:39FromDiscord<that_dude.> I'll use the mixin like you recomended anyways
00:54:55FromDiscord<that_dude.> This is more of a follow up thing now
00:55:00FromDiscord<that_dude.> (edit) "This is more of a follow up thing now ... " added "for me"
00:55:14FromDiscord<Elegantbeef> `arr = default(array[4, cstring])`
00:55:44FromDiscord<heysokam> In reply to @Elegantbeef "`arr = default(array[4, cstring])`": yeah, but sometimes I need to pass `["AnActualValue"]` to the `=`
00:55:56FromDiscord<Elegantbeef> Nim doesnt have shortcuts for array literals
00:56:05FromDiscord<Elegantbeef> Make a macro or find the one I posted eons ago
00:56:33FromDiscord<heysokam> what could i search for? i don't remember seeing that
00:56:44FromDiscord<Elegantbeef> https://forum.nim-lang.org/t/10037#66190
00:57:42FromDiscord<Elegantbeef> In your case it'd be `makeArr(4, "Bleh", ...nil)`
00:57:46FromDiscord<heysokam> leyendary. that's exactly what I was trying to make with a generic function 🙈
00:58:19FromDiscord<Elegantbeef> Hmmmm you might be able to do this with a generic
00:58:29*azimut joined #nim
00:59:34FromDiscord<heysokam> yeah but im failing rn, so was searching for the easier alternative
00:59:49FromDiscord<Elegantbeef> I more meant that inquistiively
01:00:28FromDiscord<heysokam> i understood that last sentence the least 🙈
01:01:24FromDiscord<heysokam> sent a code paste, see https://play.nim-lang.org/#ix=4E82
01:01:27FromDiscord<heysokam> but have 3 versions, and some don't really work
01:02:22FromDiscord<Elegantbeef> Nothing there should not work really
01:03:55FromDiscord<heysokam> sent a code paste, see https://play.nim-lang.org/#ix=4E83
01:04:05FromDiscord<heysokam> i had this one hardcoded... but... yeah
01:11:29FromDiscord<Elegantbeef> So odd, apparently a `cstring(nil)` at compile time gets emitted to a string that points to `"\0"`
01:13:26FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4E84
01:13:28FromDiscord<Elegantbeef> Using procedures is simple enough
01:13:41FromDiscord<Elegantbeef> And when you want custom spread you can use `spread = bleh`

03:54:28FromDiscord<terrygillis> I'm feeling like I'm being trolled by the Nim compiler again because now suddenly I cannot find the output exe file with `nim c file.nim` and `nim c -r file.nim` just output hints and `....................` and then immediately exits
03:55:09FromDiscord<terrygillis> but this time it's not resolving itself after a few attempts and computer restarts like previous hiccups
03:55:18FromDiscord<Elegantbeef> Any user configs being loaded?

03:57:24FromDiscord<Elegantbeef> If those are the only two it makes no sense for this behaviour
03:57:37FromDiscord<Elegantbeef> does `nim --outDir:./ file.nim` work?
03:59:27FromDiscord<terrygillis> nope
03:59:51FromDiscord<Elegantbeef> throw a `-f` in there
04:01:44FromDiscord<terrygillis> the peculiar thing is that it still outputs the exe files for other nim files in the same folder except for this particular one (which doesn't even appear in the nimcache folder)
04:02:09FromDiscord<terrygillis> In reply to @Elegantbeef "throw a `-f` in": it doesn't work 😭
04:02:21FromDiscord<Elegantbeef> This doesnt make any sense `--listcmd` then
04:02:39FromDiscord<Elegantbeef> It might be a compiler crash
04:02:59FromDiscord<Elegantbeef> Actually yea it's a compiler crash
04:03:05FromDiscord<Elegantbeef> so build a debug compiler and use that to compile it
04:06:02FromDiscord<terrygillis> I tried changing that file's name and still nothing shows up in the nimcache folder. I guess it has something to do with code in that file but I can't find out why.
04:06:28FromDiscord<Elegantbeef> Use a debug compiler to hunt the bug
04:06:33FromDiscord<terrygillis> In reply to @Elegantbeef "so build a debug": How do I do that?
04:06:46FromDiscord<terrygillis> compile from source?
04:07:11FromDiscord<Elegantbeef> Yea
04:08:14FromDiscord<Elegantbeef> Or thereabouts

04:48:00FromDiscord<terrygillis> thanks I found out the problematic from the souce compiled compiler
04:48:29FromDiscord<Elegantbeef> Nice now min repro and make an issue 😛
04:49:18FromDiscord<terrygillis> It's my fault and not the compiler's really, but an error message instead of shutting itself down would have been useful
04:49:28FromDiscord<Elegantbeef> What'd you do?

04:50:32*cm quit (Ping timeout: 240 seconds)
04:50:32*cm_ is now known as cm
04:50:44FromDiscord<terrygillis> It turns out I used a template instead of proc when there's recursion. Just changing one word `template` to `proc` solved everything.
04:51:37FromDiscord<terrygillis> But still, an error message instead of quietly die would have saved tons of time debugging it
04:51:46FromDiscord<terrygillis> (edit) "die" => "dying"
04:53:51FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4E8I
04:55:17FromDiscord<terrygillis> somehow the compiler doesn't show anything at all and the debug compiler says some thing like `too nested call` without mentioning it's from a template, but that's enough to guide me to the right solution
04:59:01FromDiscord<Elegantbeef> You likely somehow bypass the check

07:46:48FromDiscord<yaarb> How do i convert a `string` to a `seq[byte]` ? ( like []byte(string) in go
07:48:17FromDiscord<Elegantbeef> There is not much reason to
07:48:55FromDiscord<Elegantbeef> you can do `str.toOpenArrayByte(0, str.high)` for any proc that takes a `openArray[byte]`, or put a `@` in front to copy to a new sequence
07:49:11FromDiscord<Elegantbeef> You also can technically cast to a `seq[byte]` but that's unsafe so do not do that

09:52:34PMunchYou're question was a bit strange though, why does using a modulo go slower than using a modulo?
09:53:12FromDiscord<odexine> the question is why does manually doing if ...: smth -= smth (manually wrapping) go slower than using modulo
09:53:33PMunchIs it?
09:53:40PMunchThe question I mean
09:53:44FromDiscord<odexine> yes

14:10:20FromDiscord<System64 ~ Flandre Scarlet> Even absolute paths don't seems to work
14:13:20FromDiscord<jviega> You're "requiring" the github URL of the common code?

14:14:33FromDiscord<System64 ~ Flandre Scarlet> and the nimble in server requires common
14:16:06FromDiscord<System64 ~ Flandre Scarlet> Oh, it has to be a git repo
14:22:15FromDiscord<jviega> That's the way that definitely works
14:22:32FromDiscord<jviega> There's also "nim develp" but I've never gotten that to work very well
14:47:36FromDiscord<heysokam> In reply to @sys64 "Oh, it has to": it can also take `requires "file://../common"`
14:48:13FromDiscord<heysokam> or a `config.nims` file that says `--path:"../common"`
14:48:47FromDiscord<odexine> In reply to @heysokam "it can also take": I’ve never heard of that, huh
14:49:01FromDiscord<heysokam> In reply to @odexine "I’ve never heard of": atlas does it, thought it should be compatible
14:49:11FromDiscord<heysokam> never heard of it either, just saw it testing atlas
14:49:17FromDiscord<odexine> It might not be compatible for nimble
14:49:24FromDiscord<heysokam> oh

15:13:06FromDiscord<heysokam> In reply to @sys64 "And in the config.nims,": I would personally take a good look at `heysokam/confy` if you need to configure the buildsystem to do system admin↵I tried already with nimscript, and it gets messy and limiting super fast. With confy you have a proper (self auto-built) executable running the show
15:13:28FromDiscord<heysokam> I had similar requirements in a project, and I never got rid of them until I ported it to confy
15:13:48FromDiscord<heysokam> to answer the question, a `config.nims` file is just nimscript, so yeah I figure it can

15:33:14FromDiscord<heysokam> In reply to @griffith1deadly "https://github.com/assimp/assimp/issues/2096 vrm ba": if its -really- based on gltf truly, then you should be able to access the common parts of the file without issues

16:12:59FromDiscord<fabricio> how many spaces do yall use to indent nim code? I use 2 spaces but the code becomes hard to read when a file grows into hundreds of lines of code so I'm thinking of switching to 4
16:14:19FromDiscord<odexine> most people do 2
16:14:26FromDiscord<odexine> if it is hard for you, then go with 4
16:15:40FromDiscord<Phil> I tend to just split stuff up when a file goes into the hundreds of jubes
16:15:48FromDiscord<Phil> (edit) "jubes" => "lines"
16:16:19FromDiscord<Phil> 200 lines tends to be around the time where that thought starts tickling me for a given module
16:17:56FromDiscord<heysokam> In reply to @fabricio "how many spaces do": if the file grows into hundreds, you have a bigger architectural problem than 2 spaces, imo
16:18:09FromDiscord<heysokam> nim has proper modules, its not C/C++
16:32:13FromDiscord<jviega> Yeah I still use 2, but do end up making indentation mistakes that would be easier to avoid w/ 4 spaces (or braces which I do not care about 🙂
16:36:25FromDiscord<nervecenter> In reply to @fabricio "how many spaces do": I write it just like Python, 4 spaces and camel_case
16:36:58FromDiscord<nervecenter> (edit) "camel_case" => "snake_case"
16:37:07FromDiscord<nervecenter> I've never liked less than 4 spaces in any language, and I haven't liked camelCase in a loooooong time
16:37:25FromDiscord<nervecenter> Totally fine with kebab-case though, I like lisps
16:37:49FromDiscord<jviega> Yeah, the problem is I try to stick to 80 columns because I'm old and 4 spaces with nim seems to leave me with too much weird wrapping
16:38:23FromDiscord<nervecenter> Careful but liberal use of Nim's punctuation-newline rule is good
16:40:53FromDiscord<jviega> I do that too, but it's not always the most readable thing either, depends on the circumstances.
16:42:59FromDiscord<jviega> For instance, if I've got a block of sequential lets, I want the names lined up, the types lined up if I feel it's important for clarity, and the assignments lined up. Wrapping in that world sucks, and it uses 80 cols pretty past if you name things well.

17:38:22FromDiscord<duskhorn> In reply to @duskhorn "I don't know where": someone help me think here↵it seems like I need to "ship" a certificate file with my app. ↵Can I somehow "mbed" a .pem file into mi executable?↵If not, do I need to make an installer?
17:40:23FromDiscord<jviega> Why do you need to ship a cert?? That is not true in the slightest.
17:41:04FromDiscord<duskhorn> then I don't understand how to solve my problem XD
17:41:13FromDiscord<jviega> The link I gave you the question was about using the windows-native cert store. They could just install OpenSSL on Windows would do the same thing. Or, you could carry around a whole cert store, but seems daft.
17:41:50FromDiscord<arathanis> In reply to @duskhorn "then I don't understand": is the issue that his machine does not have an SSL cert set up?
17:42:08FromDiscord<arathanis> Lots of http clients by default won't allow non-secure requests unless you specifically enable it.
17:42:16FromDiscord<duskhorn> In reply to @arathanis "is the issue that": probably? I'm gonna ask him
17:42:33FromDiscord<arathanis> if he has not done something like let's encrypt i imagine a request to have that kind of error

17:42:50FromDiscord<arathanis> (edit) "to" => "would"
17:43:10FromDiscord<jviega> Not if it works from another machine to the same server
17:43:23FromDiscord<duskhorn> In reply to @arathanis "Lots of http clients": I mean. I used this↵https://nim-lang.org/docs/httpclient.html
17:43:28FromDiscord<jviega> That error indicates it's not finding the local cert store
17:43:43FromDiscord<jviega> That it GOT a cert but can't validate it
17:43:47FromDiscord<arathanis> In reply to @jviega "Not if it works": If the URL is hard coded as an external URL it will still go over the internet and fail even if its technically on localhost
17:44:30FromDiscord<jviega> It's not going to give an error about no cert when you don't make a TLS connection
17:44:31FromDiscord<duskhorn> I had the same error at first, I did this and it got fixed↵https://github.com/nim-lang/nimble/issues/904#issuecomment-808376364
17:44:49FromDiscord<arathanis> @duskhorn look at this section: https://nim-lang.org/docs/httpclient.html#sslslashtls-support
17:45:36FromDiscord<arathanis> you might only need `var client = newHttpClient(sslContext=newContext(verifyMode=CVerifyNone)))`
17:45:39FromDiscord<jviega> Yes, that is saying the same thing, you need to make sure OpenSSL (which nim is using) has root CA information so it can validate.
17:45:57FromDiscord<arathanis> i don't recommend it but if that fixes it its beacuse your friend's server is not SSL secured.
17:45:58FromDiscord<jviega> You can copy them in yourself, hook up to the windows one, or whatever
17:46:01FromDiscord<arathanis> pretty common issue.
17:48:37FromDiscord<arathanis> if that does not fix it, jtv's suggestion to bundle a cert is probably the right way.
17:49:06FromDiscord<jviega> That wasn't my suggestion at all.
17:49:22FromDiscord<jviega> Nor should you do CVerifyNone, that's a horrible idea
17:49:44FromDiscord<arathanis> oh you meant root certs
17:50:05FromDiscord<arathanis> In reply to @jviega "Nor should you do": im not saying its the right thing to do, im saying try it and if it fixes it then you know whats happening and can now approach the situation.
17:50:08FromDiscord<arathanis> (edit) "situation." => "situation correctly."
17:50:12FromDiscord<jviega> I said do it right, either use the Windows cert store or install a root CA store if it's too hard
17:50:27FromDiscord<jviega> I'd pin a cert before I'd turn off TLS
17:50:38FromDiscord<jviega> Tho that's much easier to do in OpenSSL3 than in 2
17:51:10FromDiscord<arathanis> if their friends server has no SSL certs for the endpoint hes pinging you can get these kinds of errors. im merely suggesting using that very small change to see if that is the cause or not
17:51:20FromDiscord<arathanis> narrowing down the issue is classic troubleshooting
17:51:38FromDiscord<arathanis> actually turning SSL off as a solution is big no
17:51:40FromDiscord<arathanis> (edit) "actually turning SSL off as a solution is ... big" added "a"
17:51:56FromDiscord<duskhorn> I'm disabling the verify so far, tho I don't think this is the issue
17:52:21FromDiscord<arathanis> then it probably needs the root cert of your friends server so it can verify
17:52:41FromDiscord<arathanis> like jtv was sasying. either install the root certs of their vendor or pin the proper cert
17:53:39FromDiscord<jviega> OpenSSL and Windows both ship with a trusted store of root certs. Shouldn't have to install anything else unless they've self-signed, which isn't likely, given if they had, they'd presumably know how to install their self-signed cert
17:55:24FromDiscord<duskhorn> It still doesn't work. I don't understand what I need to do right now tbh lol
17:56:18FromDiscord<duskhorn> you said something about root certs, is it something on my app's end, my friend's pc or his sevrer?
17:56:21FromDiscord<duskhorn> (edit) "sevrer?" => "server?"
17:56:34FromDiscord<jviega> If he can hit the URL in a browser w/o error then it's going to be the link I posted you or install the OpenSSL roots
17:57:20FromDiscord<arathanis> when you connect to your friends server, there is an SSL handshake where certificates are exchanged. Your app uses the built-in cert store on the device to verify the cert from the server. Our current assumption is the machine running the application and pinging the server is failing to verify your friend's server's certificate.
17:57:21FromDiscord<jviega> It's a bit of both. If your friends' server has the openssl store installed, then your app will work. Otherwise your app needs to use the windows one (I think that link I gave you) or drop off the OpenSSl store.
17:57:25FromDiscord<duskhorn> we can both hit the url with no errors
17:57:37FromDiscord<arathanis> cert issues are the best
17:58:27FromDiscord<jviega> Your app is not finding the info it needs to validate, as OpenSSL does not look at the Windows store itself.
17:58:38FromDiscord<jviega> But the browsers certainly do.
17:58:58FromDiscord<duskhorn> so my app needs to load the ssl store somehow. is that the issue?
17:59:04FromDiscord<jviega> Yes
17:59:22FromDiscord<jviega> You either need to integrate w/ the windows one or automatically bring the OpenSSL one.
18:00:17FromDiscord<duskhorn> ok but why is this not an issue on linux then? I remember doing something like this with an http server sending POSTs to a different server?↵Is it a Windows quirkiness?
18:01:10FromDiscord<jviega> Because every distro uses the OpenSSL cert store
18:01:17FromDiscord<jviega> And every other crypto library does too
18:02:39FromDiscord<jviega> Even MacOS pre-installs it, even though they also have their own secure enclave for cert storage.
18:03:01FromDiscord<duskhorn> so hold up a second though
18:03:09FromDiscord<duskhorn> hm
18:03:11FromDiscord<duskhorn> ok I got it
18:04:16FromDiscord<duskhorn> Ok but suppose you need to ship an actual application to users, how do you do this? Whats the most convenient thing to do? Trying to use the windows certs or some other thing?
18:04:24FromDiscord<jos7388> is there a binding generator to generate rust bindings for nim code?
18:04:27FromDiscord<jos7388> kind of like the reverse of nbindgen
18:19:23FromDiscord<jviega> I'd probably try to get the Windows cert store working yes
18:23:21FromDiscord<duskhorn> In reply to @jviega "I'd probably try to": ok, thank you both @jviega and @arathanis!

20:11:33FromDiscord<jos7388> the idea in general is good
20:11:40FromDiscord<jos7388> i found genny and i might use that instead of --header
20:41:10FromDiscord<.maverk> is there any difference between using ``float64`` or ``float`` ?
20:42:35Amun-Ranot on 64-bit arch
20:42:37FromDiscord<Andreas> In reply to @.maverk "is there any difference": no difference when your on a 64-bit CPU.
20:43:08FromDiscord<.maverk> In reply to @Andreas "no difference when your": so ``float`` is a c datatype in nim ?
20:45:05Amun-Rano
20:45:33FromDiscord<Andreas> @.maverk not sure, but there is a `cfloat`-type, so no. `float` is 32-bit on 32-bit-arch and 64-bit on 64-bit Cpu
20:45:37FromDiscord<.maverk> In reply to @Amun-Ra "no": then what ? why do we need float when we have float64 ?
20:46:15FromDiscord<.maverk> In reply to @Andreas "<@1021771961040375900> not sure, but": oky now i understand
20:46:20FromDiscord<.maverk> machine dependent
20:46:46FromDiscord<Andreas> In reply to @.maverk "then what ? why": convenience, and when you compile for a 32-bit platform `float` works too
20:46:53Amun-Rafloat has architecture dependent length, if you want a specific length regardless of cpu arch, use either float32 or float64
20:47:08FromDiscord<.maverk> In reply to @Andreas "convenience, and when you": but works on windows ?
20:47:28FromDiscord<Andreas> In reply to @.maverk "but works on windows": not sure, not living there...
20:47:46Amun-Ra.maverk: it does
20:47:48FromDiscord<.maverk> In reply to @Andreas "not sure, not living": i see
20:47:57FromDiscord<.maverk> In reply to @Amun-Ra ".maverk: it does": now i understand it
20:48:04FromDiscord<.maverk> it is a machine dependt type
20:48:14FromDiscord<.maverk> it can be 64 on 64 and 32 on 32
20:48:26FromDiscord<.maverk> float is both float32 / float64
20:48:40Amun-Rawell, it's either 32 or 64
20:48:51FromDiscord<.maverk> In reply to @Amun-Ra "well, it's either 32": thank you brother
20:48:59FromDiscord<.maverk> In reply to @Andreas "not sure, not living": thanks brother
20:48:59Amun-Rano worries mate
21:29:01FromDiscord<konsumlamm> actually, `float` is always `float64`
21:30:57FromDiscord<.maverk> In reply to @konsumlamm "actually, `float` is always": why always ?
21:31:20FromDiscord<.maverk> if it is always 64 what is the benefit of it then ???
21:31:34FromDiscord<konsumlamm> ask Araq
21:43:17*genr8eofl_ quit (Ping timeout: 245 seconds)
21:44:46FromDiscord<djazz> In reply to @konsumlamm "actually, `float` is always": Learned the hard way when coding for embedded. Float was slower than float32, and float32 was silently interpreted as float64 in compiletime.
21:44:46*genr8eofl_ joined #nim
21:48:17FromDiscord<Chronos [She/Her]> float32 treated as float64? Huh?
22:06:29*advesperacit quit ()
22:19:07FromDiscord<Elegantbeef> The VM should mimic the host, so it's likely just that whole `floatVal: BiggestFloat`
