Loqi [paulrobertlloyd] #287 RFC: Time zone support
#
aaronpk nice
#
aaronpk i'm a litle confused on the labeling of "ignore" in some of them, but i think you got the options all laid out
#
aaronpk is almost done with his talk for activitypub conf
#
aaronpk explaining oauth and indieauth to the activitypub audience
#
aaronpk it should be available tomorrow :)

[fluffy] Does video.js have instructions on how to do the HLS thing? Every time I go down the rabbit hole of trying to self-host HLS video I always find a bunch of things that just show a single-minded “here’s how to encode Big Buck Bunny” in a weirdly hardcoded way and I lose interest.
#
Ruxton [fluffy]: have a look at owncast if you're looking to do self-hosted live HLS
#
[fluffy] There’s plenty of things for live HLS, but I’m talking about encoding a playlist.
#
[fluffy] taking a fixed video file and converting it to HLS playlists and segments.
#
Ruxton ahh yep, there's some interesting stuff around that was started by some news media dudes called snickers that does that
#
[fluffy] Like that feels like a thing that should have an ffmpeg very-long-one-liner script or something.
#
[fluffy] https://github.com/snickers/snickers ? looks like a good starting point, thanks
#
Ruxton yep
#
Loqi [snickers] snickers: :chocolate_bar: An open source alternative to the video cloud encoding services.
#
Ruxton its not really worked on anymore
#
[fluffy] and it’s also an HTTP API, I just want a heckin’ commandline tool
#
Ruxton oh ok
#
[fluffy] like, insert video file, retrieve a bunch of .m3u8 and .m4v (or whatever) files
#
Ruxton >> ffmpeg -i input.mp4 -profile:v baseline -level 3.0 -s 640x360 -start_number 0 -hls_time 10 -hls_list_size 0 -f hls index.m3u8
#
Ruxton adjust size as you choose
#
Ruxton it wont generate adaptive HLS though
#
[fluffy] adaptive HLS is just a matter of generating a bunch of sizes and then having a master playlist that collates them, right?
#
Ruxton you'd have to write something to generate multiple -s and encoding levels wth ffmpeg and then mash them together
#
Ruxton yeah :)
#
[fluffy] thanks
#
[fluffy] not that I’m having any luck finding any non-RFC-speak documentation of what goes into the master .m3u8
#
[fluffy] seems like everyone just wants to sell expensive software to make this “easy”

#
aaronpk [fluffy]: You just described my evening 😂
#
aaronpk All the blog posts and everything makes it sound like it's going to be so easy but then fail to give actual practical examples
#
aaronpk I'm determined to get this video posted to my site as entirely static files with a tiny bit of JS and I'll document what I did to make that happen
[jeremycherfas] joined the channel
#
[fluffy] yeah I was asking those questions prompted by your post at 5:51 :)
#
aaronpk Has it been that long already 😭
#
aaronpk Even just finding the download link for apples tools was a real challenge
#
aaronpk they break urls and UIs all the time so half the SO answers are wrong now
#
aaronpk we'll I'm going to bed now, but I will have this done and written up by 10am tomorrow

@dailydotdev ↩️ Here is another excellent daily tip by @DailyDevTips1. This time he tells us about Webmentions. A new way to discuss and interact on the web. https://app.daily.dev/posts/1Dga3S5Yx (twitter.com/_/status/1308740961313398787)

GWG [James_Gallaghe]: Editing the weather page?
#
[James_Gallaghe] My weather station?
#
[James_Gallaghe] Oh, yeah. I’m thinking about doing some weather things.
jonnybarnes and j605 joined the channel
#
GWG [James_Gallaghe]: I love to chat weather stuff
#
[James_Gallaghe] I have a trick up my sleeve that I am going to build inspired by the weather style sheet example.
#
[James_Gallaghe] I hope to build a weather feature into my site tomorrow and then write about it.
#
[James_Gallaghe] You have a weather sidebar item on your site, right?
#
GWG [James_Gallaghe]: I have a lot more options
[chrisaldrich] joined the channel
#
GWG But I have not hooked up my own data yet, even though I have it... I'm using the US National Weather Service because I have not written the logic to only show my data when I'm at home and show 3rd party when I'm not
#
GWG I post weather as part of the location property of my post
#
GWG I should update my part of that page
#
Loqi yea!
#
[James_Gallaghe] What are you using to collect your own data?
[jgmac1106] joined the channel
#
[tw2113] depends on the type of data and if i have anything auto-recording it
#
[tw2113] for example for awhile I was tracking “checkins” for coffee shops, from the select handful I frequent, but with Covid that kind of stopped and “died”
#
[tw2113] I was just using a form to record those visits
#
[James_Gallaghe] I meant the weather data :)
#
[tw2113] ah, sorry, missed seeing the previous convo

#
[James_Gallaghe] Interesting. I only have my Raspberry Pi for sensing and I decommissioned my weather station (after only a few days in operation) because it was too much to maintain 🙂

@adam_greenough ↩️ Webmentions is a nice middle ground I think! (twitter.com/_/status/1308829763159625728)
#
@remkusdevries ↩️ Webmentions, if we’re honest, is long overdue. And notfications. P.s. what’s your aversion to using headings in post content? :P (twitter.com/_/status/1308831774550757376)
KartikPrabhu and NinjaTrappeur joined the channel
#
GWG [James_Gallaghe]: How so? I just change the batteries every few months. Otherwise it transmits data to a computer on the 433mhz band
#
GWG Used to use a Pi but the database stuff wears it out
#
[James_Gallaghe] You have your Pi run in batteries? Interesting. I only keep my Pi on during the day when I need it so the weather station has been offline a lot.

#
@adam_greenough ↩️ Sorta! Webmentions allows submission of reply URLs (or can automatically pick them up from socials). It is an IndieWeb standard. Lots of integrations out there already for various site generators/CMS. https://indieweb.org/Webmention (twitter.com/_/status/1308843038895210497)
#
GWG [James_Gallaghe]: No, the sensors run on batteries
#
GWG The Pi or the computer just has a SDR attached to pick up the signal
#
[James_Gallaghe] Ah, that makes sense.

#
timotimo that hls is http live streaming?
#
timotimo probably a safe assumption
#
timotimo huh, there's a little hitch at about 00:45 where a loading throbber briefly appears and there is a skip in video and audio
[LewisCowles] joined the channel
#
aaronpk That's it switching to a different resolution
#
aaronpk safari does better with native HLS support
#
timotimo i'm sure there is already a well-known answer for this, but how do you deal with apps that show you an instrumented browser to do your login in? like, it could just show a green lock and the html it got from the page legitimately, but insert some shady javascript?
#
aaronpk It won't act the same as the real browser
#
aaronpk you could make a pretty convincing fake, but there will always be something a little off
#
timotimo i would assume an average user might even be bamboozled into typing their username and password into a browser that looks completely off
#
aaronpk One of the other ways is to stop using passwords and rely on hardware authenticators like WebAuthn which can't be phished at all
#
timotimo i've got an OTP app on my phone already to secure stuff like github or paypal, but that's different, right?
#
aaronpk yeah OTP is phishable
#
aaronpk that’s why there’s always warnings like “dont give this code to anyone”
#
timotimo right, it doesn't encode intent at all
#
timotimo i haven't heard of WebAuthentication before today, though
#
timotimo tangentially, did you make the cat imagery for the stickers yourself, or hired an artist?
#
[snarfed] also if you’re diligent about using a password manager, and only use it to autofill, never type or paste a password manually, you get much of the same anti-phishing benefits as with U2F/security keys
#
[snarfed] (ideally combine both, though!)
#
[snarfed] upshot is, security is hard, it’s an arm race, we’re never done 😭
#
aaronpk I'm super optimistic about WebAuthn because it is the first time we've seen cooperation from everything from the hardware under the CPUs to the operating system to the browser to the websites
#
aaronpk timotimo: the cats are by an illustrator, same one who does the cats for ohmydollar.com and MeowBox
