03:29:38def-pri-pubI'm having an issue with trying to create a new Table for a custom `object` I've defined.
03:30:46def-pri-pubI've git this object here: https://github.com/define-private-public/toybox/blob/master/nim_js/3d_canvas_cube/cube.nim#L14
03:31:06def-pri-pubBut when I try to run this line:

05:28:46subsetpark> cube.nim(117, 53) template/generic instantiation from here
05:28:46subsetparkIn general, what does this error message mean? I seem to only see it when there's some other, more concrete message about something obviously wrong
05:29:23*yglukhov quit (Ping timeout: 245 seconds)
05:35:19ftsfsubsetpark, it means problem happened in template generated code, and the thing that generated it was on that line.
05:37:34subsetparkAh... I see. So, not that 'template/generic instantiation' itself is bad, but just 'if you're looking for the template/generic that let to <problem>, look here'
05:37:51subsetparkSo does that mean we can always expect *some* other more specific error message?
05:39:34ftsfyep i think so
05:39:57ftsfit's not an error message, but it tells you where the related error message happened
05:42:58subsetparkthat makes a lot of sense
05:43:24subsetparkthe wording is not very clear, but now i understand
05:45:19subsetparknext question... what's the difference between nake and the task functionality in nimble? they seem to overlap a lot.
05:47:15Araqnake works by compiling a builder app, nimble runs the tasks via an interpreter.
05:47:32Araqboth approaches have their cons and pros.
05:47:58Araqnake supports Android builds out of the box afaik, Nimble doesn't
05:48:53Araqthe Nimble task API was inspired by nake ;-)
05:49:09subsetparkah, very interesting
05:49:20def-pri-pubAlright, the `html5_canvas` package is ready for the prime time: https://gitlab.com/define-private-public/HTML5-Canvas-Nim
05:49:24subsetparkI never thought about compiling builder apps
05:49:31def-pri-pubI'll make a post about it on my blog tomorrow. Night guys.

10:00:58FromGitter<andreaferretti> I have a couple of questions on the new foreignDep feature of nimble
10:01:15FromGitter<andreaferretti> Does it support alternatives? (install this *or* that)
10:02:17FromGitter<andreaferretti> Does it work with transitive dependencies? (package A needs a foreignDep; do I get a suggestion when installing package B that depends on A)?
10:03:10AraqGustavoLapasta: unlikely, but what does this field do
10:03:32Araqandrea: transitivity should work out of the box.
10:04:09Araqno support for alternatives, I'm afraid. you can have an 'if' in your nimscript and try to make the choice for the user

17:16:46FromGitter<martinium> I have a stupid question. Does Nim have good parallelization support or does it only support concurrency?
17:18:03kulelu881 comment stood out from the recent submission: "A casual skim through the top of the commit history indicates that Araq (Andreas Rumpf) is still doing almost all of the development. That's a red flag — being responsible for a complex language, compiler, standard library and documentation is a lot of work. (And it's of course a dangerous bus factor.)"
17:18:35dom96martinium: it supports parallelization fairly well
17:18:53dom96Calinou: Think you'll be able to use some of that time to work on the site?

17:24:03Calinouapparently, Linux is still pretty bad with hiDPI displays :(
17:24:16Calinouwhile the latest Windows 10 builds are good for the most part with it
17:24:38Calinouon a clean install, nearly everything worked out of the box, including automatic display rotatio, touch screen, keyboard disabling in tablet mode...
17:25:14FromGitter<martinium> @calinou recent linux builds have excellent hidpi support
17:25:19FromGitter<martinium> At least ubuntu and arch
17:25:32Calinouwell, the core OS might (with KDE or Unity) but the applications will hate it

17:26:05FromGitter<martinium> Linux rocks
17:26:24FromGitter<martinium> @cheatfate what about on linux?
17:26:54kulelu88people run servers on MacOS? wut?
17:27:13def-pri-pubCalinou: when Linux comes anything that visually related it always seems to be a shitshow for the end users. The only place where I've seen Linux excel in graphics is Ray Tracers (or at least running tem)
17:27:17def-pri-pubthem*
17:27:18FromGitter<martinium> Back in the day
17:27:27FromGitter<martinium> Some people did @kulelu88
17:27:36FromGitter<martinium> Back in the xserve days
17:27:44FromGitter<martinium> But i think for basic sites and file servers
17:27:50def-pri-pubI still get a crap ton of screen tearing when writing OpenGL apps or watching YouTube videos.
17:27:59cheatfatemartinium: linux/windows supported by threads.nim, there only problem with macos, because it don't support to set thread affinity to cpu.
17:28:04FromGitter<martinium> MacOS is not a good os for performance. Linux and windows obliterate it
17:28:37FromGitter<martinium> All HPC set ups use either linux or windows
17:28:40FromGitter<martinium> 99% use linux
17:29:42FromGitter<martinium> @cheatfate so threads.nim is for both multithreading/concurrency and for parallelism?
17:31:06def-pri-pubmartinium: I'm not sure what's really happended with OS X as of late in the terms of performance :/
17:31:07cheatfatemartinum: threads.nim is a tool using which you can implemenent parallelization and concurrency
17:31:16*PMunch quit (Quit: leaving)
17:31:36def-pri-pubI had a late 2014 Mac Mini that I updated to Sierra in Mid 2015 and it completely drained all of the speed from the system.
17:32:03cheatfatemartinum: BSD is faster then linux by design, and macos is using bsd's kqueue, but you are right nobody wants to use macos (maybe because it expensive?)
17:32:03def-pri-pubWhat also sucks too is that I can't put any more RAM into the thing. It's soldered onto the mainboard (unlike previous models).
17:32:37FromGitter<martinium> @def-pri-pub it is bloated. Apple cares about normal non-geeks and having a pretty UI with usability over performance
17:33:41FromGitter<martinium> MacOS even hides the real unix file system from users by default
17:33:52FromGitter<martinium> Something devs need to see and use
17:33:53def-pri-pubmarinium: I've also heard from a few of my Art friends that they're starting to jump ship back to Windows because they haven't like Apple as of the past few years.
17:34:17Calinouthese days, Microsoft is becoming a much stronger player vs macOS
17:34:17FromGitter<martinium> Yeah, that myth has taken a long time to dispel
17:34:34Calinouthey make nice hardware (Surface Pro, Surface Book), and they show what they're capableof
17:34:36def-pri-pubwhat myth?
17:34:39FromGitter<martinium> Windows is much better for artists of all genres be it music movies artwork
17:34:48kulelu88much stronger player ? they own 80+% of the desktop market
17:34:48CalinouVisual Studio Code is also a pretty nice editor (with good Nim support by the way)
17:34:49FromGitter<martinium> The myth that macs are better for graphics work
17:35:00Calinoukulelu88: I mean, innovation and coolness-wise
17:35:04def-pri-pubCalinou: Microsoft has really stepped up their game since they got rid of Balmer
17:35:06FromGitter<martinium> Windows outperforms them in all art software
17:35:07CalinouMicrosoft used to be "lol, boring, crashes all the time"
17:35:15Calinounow it's closer to being the trendy thing
17:35:26def-pri-pubWindows is going to be the new Hipster OS
17:35:29Xemartinium: OSX used to be the top of the kek
17:35:30FromGitter<martinium> Windows 7 ushered the era of rock solid stability
17:35:51FromGitter<martinium> Used to be a long time ago since they were the first to work with color graphics
17:35:51cheatfatemartinum: try to use wacom tablet with windows (restart services and drivers all the time)
17:36:05FromGitter<martinium> I have one and it works well
17:36:10FromGitter<martinium> Using win 10
17:36:35cheatfatemartinum: mine is always not working after sleep
17:36:51FromGitter<martinium> I uninstalled windows completely for ubuntu since rarely game anymore but win 10 is rock solid
17:37:23FromGitter<martinium> Lots of backdoors and spying but still better than mac and more performant lol
17:38:06FromGitter<martinium> If linux had more professional grade software available it would take over
17:38:14cheatfatemore performant where? network? graphics? storage?
17:38:43FromGitter<martinium> As compared to mac
17:38:52FromGitter<martinium> More performant in cpu speed
17:38:57def-pri-pubI really just want the graphics stack to get better. The only way I feel that's going to happen is when it has more Market Share.
17:39:02FromGitter<martinium> Ui also more responsive
17:40:01FromGitter<martinium> Windows and mac are responsible for entire generation of people being computer illiterate
17:40:09FromGitter<martinium> Dumbing down tasks and interfaces
17:40:18FromGitter<martinium> Linux didnt coddle anyone
17:40:52FromGitter<martinium> Most people can only open a browser and go on web in addition to maybe using an office suite
17:41:09FromGitter<martinium> Thankfully most colleges use linux in their cs programs
17:41:34FromGitter<martinium> Windows 8 was a big loss for MS
17:41:35def-pri-pubmartinium: I beg to differ on the "computer illterate part," It's moreso that most of the application that people now run are in a browser, and they are mainly sites like "Facebook," "YouTbue," "Twitter," etc.
17:41:51FromGitter<martinium> Thats just web though
17:42:03def-pri-pubIt's the web & smartphones that have made people dumber
17:42:04FromGitter<martinium> They dont know how to move through their filesystem
17:42:16FromGitter<martinium> Dunno what anything means
17:42:42FromGitter<martinium> Web more information than ever yet people have gotten dumber because they seek pleasure and fun over knowledge
17:43:19FromGitter<martinium> Thats why languages like Nim with approachable syntax and speed can bring more back over into the knowledge realm
17:43:42FromGitter<martinium> New gen of school kids see C code and think its esoteric
17:44:04FromGitter<martinium> Due to the shift towards dumber easier interfaces etc
17:45:50FromGitter<martinium> Seems like that is changing though hopefully continues and more and more people are adopting nix thanks to web dev roles and scientific computing all being done on linux/unic
17:45:53FromGitter<martinium> Unix*
17:46:12def-pri-pubmartinium: yeah, I'm a little saddened by that. I used to be a tutor (for CS) at my University.
17:46:55def-pri-pubThey would start all of the kids out on Python. It's not a bad langauge, except for the fact that it doesn't enforce type. I swear to god half of the issues I had to solves for students in the first weeks related to type issues.
17:46:57FromGitter<martinium> Call me crazy but C made a lot of sense to me even though I only did the basics in it
17:47:34FromGitter<martinium> Python hides too much. Abstracts how things work that programmers should know about
17:47:38def-pri-pubI did a BASIC syntax first, then another BASIC variant (which compiled to C++). They both enforced Type strictly. Then I moved onto C++.
17:47:45FromGitter<martinium> Breeding an entire gen of mediocre programmers
17:48:38FromGitter<martinium> I am still learning and have dabbled in the low level langs but since I have a day job I wanted modern syntax and speed in a compiled lang. Nim is perfect for it
17:48:39def-pri-pubMy department was more concerned with first teaching them the concepts of CS first (e.g. linked lists and algorithms) and then the hardware implementation next(Assembly and CPU architecture)
17:48:52FromGitter<martinium> Nice
17:49:03FromGitter<martinium> I def need to learn assembly
17:49:09FromGitter<martinium> Sometime in future
17:49:20def-pri-pubEh, I wished they force everyone to take a "Learn Programming" class first before making them take the Intro to CS course.
17:49:51def-pri-pubTry MIPS first. It's kind of the de-facto learning language. It's also fun too.
17:50:18FromGitter<martinium> I'll look into that
17:50:37FromGitter<martinium> Nim lets you embed raw assembly in the code I think as well
17:50:48def-pri-pubhttps://www.amazon.com/Computer-Organization-Design-Fifth-Architecture/dp/0124077269/ref=sr_1_1?ie=UTF8&qid=1484157033&sr=8-1&keywords=computer+architecture+and+organization+hennessy+and+patterson
17:50:53def-pri-pub^^^
17:51:13def-pri-pubThat book. Teaches you MIPs and how the CPU works.
17:51:47def-pri-pubThere' also a follow up book too that goes more into the CPU:
17:51:48def-pri-pubhttps://www.amazon.com/Computer-Architecture-Fifth-Quantitative-Approach/dp/012383872X/ref=sr_1_3?s=books&ie=UTF8&qid=1484157084&sr=1-3
17:52:25def-pri-pubThe two most impactful CS courses I think I ever took back at Uni where Computer Organization & Computer Architecture.
17:53:04FromGitter<martinium> Nice
17:53:15*shodan45 quit (Quit: Konversation terminated!)
17:53:17FromGitter<martinium> I remember when I was curious about how circuits work
17:53:42FromGitter<martinium> Then realized that the circuit instructions are now atomically small
17:53:45FromGitter<martinium> Mind blown
17:53:54FromGitter<martinium> Cpu's seem like magic
17:54:17FromGitter<martinium> When you learn how they really work
17:54:38def-pri-pubGet that first book then. It's a pretty heafty read but really insightful. It's on my TODO list to re-read it.
17:56:24*rupil joined #nim
17:56:27FromGitter<martinium> I will def do that
17:56:40FromGitter<martinium> Will take some time to get through that beast though
17:56:57FromGitter<martinium> Thats as low level as one go before machine code
17:57:16Calinouhere, students are taught PHP as first language, JavaScript as second
17:57:19Calinoubut this is not CS, it's a multimedia course
17:57:50def-pri-pubwhat-chu-talkin' bout martinium. Machine code has a 1-to-1 correspondance with Assembly (unless you're using pseudo instructions)
17:58:33FromGitter<martinium> Oh ok thats good then 
17:58:51FromGitter<martinium> Php for multimedia course makes sense if they are doing web tasks
17:58:58FromGitter<martinium> Php7 is fast
17:59:14FromGitter<martinium> Important thing is being able to study quality code
17:59:28FromGitter<martinium> I hear php suffers from lots of spaghetti code
17:59:35euantorMy first language was Visual Basic .NET, taught in high school. At least it kind of enforces types, more than Python anyway
17:59:41CalinouPHP 8 will be even faster, it'll have a JIT!
17:59:57Calinouyes, tons of PHP code is crap; it doesn't mean you can't write good PHP code
17:59:58FromGitter<martinium> I love this focus on performance
18:00:09FromGitter<martinium> Its all due to mobile/portable smart devices
18:00:23FromGitter<martinium> Gotta get the most performance to save battery
18:00:25Calinouif you use a well-established framework and modern (5.6+, 7.0+) practices, you can end up having quite clean code
18:00:38Calinouwell, PHP runs on the back-end, there's no battery life there
18:00:51Calinouit's just that PHP used to be slow as molasses
18:02:22*yglukhov joined #nim
18:02:46def-pri-pubI feel like people who write PHP should be switching to Hack and HHVM instead.
18:02:51FromGitter<martinium> It was slower than python
18:03:01FromGitter<martinium> But now its much faster
18:03:15FromGitter<martinium> Php 7 faster than hhvm
18:03:26FromGitter<martinium> Its actually pretty good
18:03:41def-pri-pubReally?
18:03:41FromGitter<martinium> As far as dynamic web languages go
18:03:46FromGitter<martinium> Yeah it is
18:04:06FromGitter<martinium> I looked at benchmarks when php7 was released
18:04:10FromGitter<martinium> Its really fast
18:04:11def-pri-pubI remember when Facebook first made HipHop to transpile their PHP codebase over to C and they crazy performance boosts.
18:04:37FromGitter<martinium> Yeah php7 now negates that
18:04:38FromGitter<martinium> Hehe

18:05:05def-pri-pubcorrection*
18:05:39CalinouHHVM is a RAM hog compared to PHP 7, too
18:05:46Calinouit's also considerably hard to build
18:06:04def-pri-pubSoon enough, the only way to write highly scalable web apps is going to be in Assembly :P
18:06:06Calinouso, for 99% of users on small VPSes, you want PHP 7, not HHVM

18:06:32CalinouGo can be used to make web apps that scale, too
18:06:38Calinouor Rust, or a JVM language like Scala
18:06:41cheatfateguys this is #nim channel
18:06:44FromGitter<martinium> But people should make efficient use of all that power
18:06:53cheatfatethis is not channel about php
18:06:58cheatfateor any other languages
18:07:00FromGitter<martinium> Otherwise its wasted potential
18:07:12def-pri-pubCalinou: other issues are going to be with memory fetch speed too.
18:07:12FromGitter<martinium> I think Nim can be great for webapps
18:07:32FromGitter<martinium> C is still considered the fastest lang behind asm
18:07:48FromGitter<martinium> So Nim with a few killer apps can make huge inroads
18:08:06dom96cheatfate: true, but I think it's okay to let a little bit of offtopic chatter from time to time
18:08:12dom96Especially when nobody else is chatting about Nim
18:08:20FromGitter<martinium> Development time would be greatly decreased while still being superfast
18:08:33def-pri-pubI was talking about writing an ORM library for Nim yesterday. I think that needs to happen first before Nim will be considered for Web Apps.
18:09:04FromGitter<martinium> @dom96 you actively working on jester?
18:09:19FromGitter<martinium> You have competition with crystal/kemal
18:09:34dom96martinium: not actively
18:09:47dom96I spent my last holidays working on Nimble
18:10:13FromGitter<martinium> I remember
18:10:55FromGitter<martinium> Hopefully I can learn enough to start feeling more comfortable. I am making many small apps a bit at a time
18:11:08FromGitter<martinium> Trying out stdlib features
18:11:13FromGitter<martinium> So I know what they do
18:11:27FromGitter<martinium> To learn how to use them etc
18:11:40FromGitter<martinium> A lot to learn but the syntax is very approachable
18:12:02FromGitter<martinium> Good for people like me who can only code after work
18:14:23FromGitter<martinium> @cheatfate are you a core contributor to Nim? Your name looks familiar

18:50:58Araqdom96: ok, fair enough. Often "syntax" doesn't mean anything though and the question could have been "compare Cython to Nim for me"

18:56:06euantorThe one thing that we're missing from the HTTP libraries (in terms of marketing anyway) is HTTP2 support. That seems to be how you sell HTTP libraries these days
18:58:01GustavoLapastaPorting c code to nim. In my machine size_t is defined as "unsigned int" so I would translate it to Nim's "uint", but c2nim translates it to a plain "int". Why isn't "uint" correct?
18:58:43AraqGustavoLapasta: it's correct, but more cumbersome to use :-)
18:59:04Araqplus unsigned is viral and suddenly you end up with strange modulo arithmetic everywhere
