2020-09-26 06:56:56 <Guest26> this is all because i couldnt get sdl-diagrams to work...
2020-09-26 06:56:58 <fraktor> dsal: Is this project open-source? I can maybe take a look
2020-09-26 06:57:06 vicfred joins (~vicfred@unaffiliated/vicfred)
2020-09-26 06:58:02 <Guest26> dsal: the data it could send could be interpreted by the haskell program, so it could be eg a command such as "restart simulation" or "convert boundaries to reflective/periodic"
2020-09-26 06:58:30 <dsal> fraktor: Alright, but I don't use standard elm layout because I wrote all this code before anyone told me about it and I thought it was ugly. heh github.com/dustin/gopro -- static is the, uh, static content. ui is the elm source.

2020-09-26 06:59:01 <dsal> socketHandler handlers sockets.
2020-09-26 06:59:52 <Guest26> this is some serious code
2020-09-26 06:59:58 hackage tasty-wai 0.1.1.1 - Test 'wai' endpoints via Test.Tasty https://hackage.haskell.org/package/tasty-wai-0.1.1.1 (GeorgeWilson)
2020-09-26 06:59:58 <fraktor> Oh wait, you didn't use the Elm architecture?

2020-09-26 07:00:55 <Guest26> dsal: i dont see where it does the visualisation
2020-09-26 07:00:59 MarcelineVQ plays a violin for the readme.md
2020-09-26 07:01:24 <fraktor> Guest26: It's not for the same kind of thing; I'm just curious about what dsal wrote lol.

2020-09-26 07:01:35 <Guest26> ok
2020-09-26 07:01:46 <dsal> MarcelineVQ: heh. nobody ever uses my programs no matter how well I document them.
2020-09-26 07:01:47 <Guest26> ah, it was about websockets
2020-09-26 07:02:26 <dsal> This is really good software lots of people should use, though.
2020-09-26 07:02:29 <Guest26> dsal: what is it for this gopro interface?
2020-09-26 07:02:34 <fraktor> I want to go back to 1980 and try to explain this: `addToast toast = Toasty.addToast toastConfig ToastyMsg toast`
2020-09-26 07:02:44 MarcelineVQ plays Agnus Dei for the code commentary :>
2020-09-26 07:03:18 <dsal> Guest26: it's a bunch of tools for managing data in gopro's cloud.
2020-09-26 07:03:31 <jdgr> Okay, was going over Haskell with my girlfriend. She's "bored" so I put studying Haskell on pause and introduced her to Scratch.
2020-09-26 07:03:38 <Guest26> extractGPMDStream filename stream = readCmd "ffmpeg" ["-y", "-i", filename, "-loglevel", "-8", "-codec", "copy", "-map", "0:" <> show stream, "-f", "rawvideo", "-"] id
2020-09-26 07:03:41 <Guest26> horrible
2020-09-26 07:04:11 <jdgr> Probably a better introduction to programming because it's visual and you can immediately do interesting things.
2020-09-26 07:04:23 × Omentiger quits (~Omentiger@cpe-24-25-246-129.hawaii.res.rr.com) (Quit: Leaving)
2020-09-26 07:04:27 <Guest26> sounds like you need a dog
2020-09-26 07:04:56 heatsink joins (~heatsink@107-136-5-69.lightspeed.sntcca.sbcglobal.net)
2020-09-26 07:05:08 <Guest26> https://ocharles.org.uk/img/2013-12-19-websockets.png
2020-09-26 07:05:29 <jdgr> We need a visual IDE for Haskell that makes the language easy and fun for beginners like Scratch is
2020-09-26 07:05:30 <dsal> Guest26: yet I've pushed a TB of video through it. I'll take a patch, but I didn't find an mpeg library that could solve the problem that line did.
2020-09-26 07:05:58 <dsal> It was enough that I had to write a parser for GoPro's metadata stream because all of their tools were unusable even as FFI.
2020-09-26 07:06:35 <Guest26> oh right, its got all those funny arguments because its a command line tool
2020-09-26 07:06:38 × fxg quits (~fxg@unaffiliated/fxg) (Ping timeout: 256 seconds)
2020-09-26 07:06:44 <fraktor> I still need to actually write a real project in Elm. Maybe I'll update my Rust/Vue project to do that
2020-09-26 07:06:57 <Guest26> hmm, maybe thats the best way to do this plotting too... just compile something to exe
2020-09-26 07:07:12 <dsal> This was my "I should try out elm" project. It works. The WS was the worst pain (which was surprising).
2020-09-26 07:07:15 <Guest26> i can easily read the .png in by refreshing the page
2020-09-26 07:07:35 <fraktor> Then again, I'm not really good at Haskell either. I still don't understand how to use Monad Transformers
2020-09-26 07:07:45 <Guest26> each time the simulation produces new data i can get the thing that watches the data dir to overwrite the plot image
2020-09-26 07:07:57 <fraktor> That's probably the easiest way
2020-09-26 07:08:04 <fraktor> I would not recommend websockets if you don't want to dive deep
2020-09-26 07:08:04 <Guest26> ok! that sounds like a plan. so how do i plot the timeseries data?
2020-09-26 07:08:09 <dsal> I just write code to solve my problems.
2020-09-26 07:08:21 <fraktor> Guest26: I don't really know. You'd need to find a Haskell library for that.
2020-09-26 07:08:27 <jdgr> That's the whole point of programming
2020-09-26 07:08:30 <Guest26> ok brb
2020-09-26 07:08:32 <jdgr> Making your life easier
2020-09-26 07:08:37 <fraktor> Not true! Sometimes it's for fun
2020-09-26 07:08:45 <jdgr> That too
2020-09-26 07:08:56 <Guest26> i soon find; https://hackage.haskell.org/package/plots
2020-09-26 07:09:18 × heatsink quits (~heatsink@107-136-5-69.lightspeed.sntcca.sbcglobal.net) (Ping timeout: 260 seconds)
2020-09-26 07:09:19 <fraktor> Great!
2020-09-26 07:09:25 <dsal> This GoPro thing is... unofficial (had to reverse engineer the API and violate all the terms of service), but the service isn't usable without it.
2020-09-26 07:09:40 <dsal> Like, I would be surprised if anyone uses their stuff at all.
2020-09-26 07:09:43 <fraktor> I've definitely used APIs in a creative way before.
2020-09-26 07:10:29 <dsal> They don't have a published API. Their web UI is *impressively* bad, and doesn't even do a lot of the things you'd want done.
2020-09-26 07:11:01 <Guest26> ah but this doesnt seem to write to a .png
2020-09-26 07:11:06 <dsal> But most importantly, when they decide they don't want to store my TB of data for $5/mo anymore, I have a commandline that will ship it all off to S3 just about instantly.
2020-09-26 07:13:01 xsperry joins (~as@unaffiliated/xsperry)
2020-09-26 07:13:33 <dsal> http://dustin.sallings.org/2020/04/29/gopro-plus.html <-- I wrote about it there. I guess I could document things since I think I've got it as stable as I want now, just in case someone somewhere has a gopro.
2020-09-26 07:14:02 <Guest26> horay! human words
2020-09-26 07:14:04 <dsal> I've worked around a crapload of bugs on their side as well. I've got this cool thing where I can do bulk updates of metadata on their end using SQL queries.
2020-09-26 07:15:02 heatsink joins (~heatsink@107-136-5-69.lightspeed.sntcca.sbcglobal.net)
2020-09-26 07:15:36 <dsal> e.g., there's some way I can upload stuff where they just can't figure out what camera it came from, but like, I can read it directly out of the EXIF or GPMD streams, so I write a SQL query that returns the metadata that I know for all of the rows where they don't know and it translates that into mutation API calls on their end. Fun stuff.
2020-09-26 07:15:53 × toorevitimirp quits (~tooreviti@117.182.182.201) (Remote host closed the connection)
2020-09-26 07:16:31 <Guest26> i guess its more of a home use tool than a lib for hackage?
2020-09-26 07:17:00 <dsal> If you just want to use the APIs, they're here: http://hackage.haskell.org/package/gopro-plus
2020-09-26 07:17:06 <dsal> and gpmf and stuff.
2020-09-26 07:17:11 <dsal> (linked in that article)
2020-09-26 07:17:18 <Guest26> oh right, thats far less impressive
2020-09-26 07:17:38 <dsal> Heh, that stuff was hard to reverse engineer and write.
2020-09-26 07:17:43 <Guest26> oh - you wrote those aswell
2020-09-26 07:17:47 × merijn quits (~merijn@83-160-49-249.ip.xs4all.nl) (Ping timeout: 258 seconds)
2020-09-26 07:17:56 <Guest26> completely impressive
2020-09-26 07:18:06 <Guest26> i cant even do a line plot
2020-09-26 07:18:12 <Guest26> :-?
2020-09-26 07:18:12 <dsal> Like, this is the *simple* case of uploading media: https://github.com/dustin/gopro-plus/wiki/Upload
2020-09-26 07:18:32 × jdgr quits (601c428b@gateway/web/cgi-irc/kiwiirc.com/ip.96.28.66.139) (Ping timeout: 256 seconds)
2020-09-26 07:18:53 <Guest26> now i want a go-pro, just to use this library....
2020-09-26 07:19:14 <dsal> But you can do server-side concatenation of multiple files (e.g., when the camera splits, or you just took multiple videos and want them to be a single one) by defining a single multi-part video across a set of files, each of which is split into 6MB chunks and uploaded.

2020-09-26 07:19:48 <dsal> The upload is completely resumable as well (since my connectivity goes out). I was uploading earlier, and then stopped for some reason (^C) and then just told it to keep uploading whatever it was doing before.
2020-09-26 07:19:48 <Guest26> but i think before too long it would become philip k dicks second variety
2020-09-26 07:20:07 <Guest26> do we have an interface to project gutenburg?
2020-09-26 07:20:19 <dsal> What would that do?

2020-09-26 07:22:24 <Guest26> idk, something like search and download? or maybe an interface to have it for use as a text corpus eg. for machine learning
2020-09-26 07:22:31 <Guest26> it has entries like this;
