jonas’ohhh
jonas’intriguing
Link MauveI probably missed some elements, and the examples are too bright in order to not have to modify the other CSS, but it’s a starting point.

jonas’even though fennec itself is dark
jonas’oh wait
Link MauveI only tested with my laptop’s Firefox, not my phone’s.
jonas’my laptop firefox doesn’t know about dark mode at all -.-
jonas’only via about:config methinks

jonas’works on my laptop’s firefox if I force it to dark
Link MauveOh, do you build it with Qt support?
jonas’Link Mauve, no, but I don’t have any gtk tooling
Link MauveI didn’t know it still supported that.
jonas’I use whatever debian does
Link MauveDebian most likely builds Firefox with GTK.
jonas’sooo... on the platform which most natively supports dark mode (android), firefox (fennec) fails to respect it for websites, while it does for its own ui?
jonas’hm, I find the syntax highlighting hard to read
jonas’not sure this is an improvement
Link MauveI could make it fully white if you prefer.
jonas’yes, that or fixing the stylesheet of the syntax highlighter
Link MauveOr figure out XML colours which go better on a dark background.
Link MauveWut, did I forget to commit the prettify.css?
jonas’oh
jonas’sorry
Link MauveNo I didn’t.
jonas’I was under the impression you only changed xmpp.css
jonas’I didn’t update prettify.css on my webserver
jonas’much better
jonas’this is great, thanks!
Link Mauve:)
jonas’pushed
jonas’need to poke the docker stuff once it’s done, but lunch first
adiaholichas joined
Link MauveI should have done that years ago…
adiaholichas left
jonas’no, that would’ve been with the old CSS ;)
jonas’huh
jonas’the change didn’t make it into the docker image
jonas’not sure why, need to look at it later, lunch first

larmajonas’, I am not a big fan of Blurhash. I think it's not really well documented. https://github.com/woltapp/blurhash/blob/master/Algorithm.md is all you get. It uses custom, digit-based base 83 encoding, doesn't support alpha channel. And as far as I can see, it's not even heavily popular. Mastodon and Signal use it, and that's basically it. It just happen to be circulated within XMPP people for some reason and the word Blurhash is even used here as a synonym for "very small image scaled up in a blurry way" by some.
pasdesushihas left
jonas’larma, no, I specifically talk about blurhash
jonas’by that I mean the entire package, because I looked at it and I consider it a reasonable and smart solution to the problem
jonas’in contrast to taking an 8x8 JPEG/PNG and scaling that up with a bilinear filter
jonas’I’m not sure how alpha channels would even work with such a technology, that needs more thought
amuza@riseup.nethas left
larmawhy do you think it's smart comparing to a simple bitmap? I wouldn't take jpeg or png because they have huge overhead for small size images
larmaclassic pc bitmap, you now this old .bmp, is much better for very small images
pasdesushihas joined
adiaholichas joined
larma4x3 = 12 32-bit colors are just 48 byte, encode them using base64 and you get 64 ascii chars. Yes a 4x3 blurhash is "just" 28 ascii chars. But given the overall overhead we have in XMPP that's not a huge thing. Also as quality of blurhash isn't exactly comparable with 32-bit color, we can easily reduce this by half (using 16-bit colors) and reach a size that is pretty close.
jonas’Link Mauve, there, it’s live (cc @ Zash)
ZashShiny, thanks Link Mauve
Link MauveWoohoo!
larmajonas’,
test image: http://larma.de/blur_sample_base.jpg
4x3 blurhash: http://larma.de/blur_sample_blurhash_4x3.jpg
image scaled to 4x3, reduced color depth to 12-bit (no alpha) and then scaled up again, both scaling used cubic interpolation: http://larma.de/blur_sample_cubic_scaled_4x3.jpg
Link MauveTbh I don’t recognise any feature of the original image in either of the 4×3.
moparisthebesthas left
jonas’larma, can you use cubic in browsers?
larmawell, you can see a rough estimate of the color
pasdesushihas left
Link Mauvejonas’, you can use any algorithm with the <canvas> API.
ZashPoint is to have something to show until you download the actual image
jonas’Link Mauve, sure
chronosx88has left
larmaThe problem is that if you don't have alpha in the preview you can't correctly display it if the final image has alpha and you want to display it on background of varying color (which we need to consider in a heterogenous environment like public XMPP network). You certainly could add an alpha component to blurhash, but then you couldn't reuse existing implementations, making it probably harder to use (and not smaller in size) than just using bitmap data.
jonas’larma, not wrong, but I wonder how that cubic interpolation of yours would look like with alpha
Calvinhas joined
chronosx88has joined
moparisthebesthas joined
larmaI guess cubic interpolation isn't that good for images that typically have alpha. It works good for photos, not necessarily for graphics
larmabut blurhash also doesn't work well for anything that is not photos, so that's a general issue for these kinds of things
jonas’exactly
eevvoorhas joined
lorddavidiiihas joined
jonas’but I guess one could pick a blurhash-y thing for JPEG input and a simple downscaled bitmap for non-JPEG input
pasdesushihas left
larmawith alpha: http://larma.de/blur_cat_base.png
image scaled to 4x4 (32-bit with alpha) and scaled up to original: http://larma.de/blur_cat_cubic_scaled_4x4.png
jonas’hm, probably OK on a uniform coloured background✎
jonas’hm, probably OK on a uniformly coloured background ✏
larmawould probably have more effect on images where more than just a few pixels on the edges have transparency
larmain any case scaling down to very small images and reducing color depth and then scaling up again gives decent enough results, at least on the same level of blurhash, if you use some more advanced interpolation. If for some reason your platform does not allow you to do this, but you can do gaussian blur, an alternative would be to use no interpolation when scaling up and then apply gaussian blur (with radius set to scaling factor) on the few "very large pixels". Results should be similar.
larmaespecially implementation work for everyone who can't use any of the existing encoder and decoders is going to be much less when being based on simple rgb bitmaps instead of complex encodings.

MattJYes
MattJedhelas also expressed an interest in it recently, maybe he'll beat me to it
SamWhitedI think a lot of distros (maybe Debian?) enable Firefox's anti-fingerprinting protections by default (which disables dark mode entirely)

lovetoxthat there is a execute action and an execute attribute and both have defaults if absent
lovetoxis beyond confusin in 0050
Zashyeah
Andrzejhas joined
lovetoxThe action "execute" is equivalent to the action specified in the "execute" attribute. If the "execute" attribute is absent, it defaults to "next".
lovetoxthat sentence is a real treat
lovetoxwhat default to next here
lovetoxthe action or the attribute

lovetoxwait, is the execute action a real action element?
lovetoxah so i can simply never send action=execute
lovetoxexcept for the first command
Zashyou MAY, or not. it's the only option at that point, so redundant
lovetoxok that makes it simpler
lovetoxbecause from a gui standpoint, if i draw buttons next, prev, etc
lovetoxbut when clicking on them i send "execute" suddenly
Dele Olajidehas joined
ZashLink Mauve, p.box (Note: ...) has black text
Lanceyou can send action=execute any time. but it's the "idk what i want, you decide for me" option. so the responder decides what actually happens
Link MauveZash, do you want to fix it, or should I do it?
ZashLink Mauve: Do *you* want to? I can, but not now.
Lancei'd wouldn't send action=execute if a user actually clicked on a prev/next/complete button, just the explicit action the user chose
Link MauveZash, I’m working on Jingle stuff.
Link MauveI can do it at some point too.
lovetoxyeah Lance thats what i also think
Lanceonly time id consider using action=execute would for some automated exchange, where i just want to fast track though the default happy path the responder wants
moparisthebesthas joined
Lancebut even then, ehhh
lskdjfhas left
lskdjfhas joined
lovetoxoh wow just found this
lovetoxIf the <actions/> possesses the "execute" attribute, that value is the default button or option. If the <actions/> does not possess the "execute" attribute, there is no default button or option.
lovetoxthats what i was actually searching
lovetoxso i just pick whatever the execute attr tells me and color my button
lskdjfhas left
lskdjfhas joined
lovetoxand i never have to actually send execute or even care what it "defaults" to if its not htere
lskdjfhas left
lskdjfhas joined
Lanceyeah, the whole execute attribute thing is entirely for UI guidance/hinting on the submitter side. if you're the responder and receive action=execute it just means you get to choose what happens instead of the submitter choosing
goffihas left
lskdjfhas left
Lancethe ambiguity in the model comes from when the responder provides (or doesn't provide any) UI hints that match what it would choose
ZashOught to have been called "default", but oh well

lovetoxi think the problem is that i trys to fill 2 jobs
lovetoxfirst provide a UI hint
lovetox2. for this rare usecase where i just want to send "execute"
lovetoxi wonder how a xmpp lib fullfills both things
lovetoxbecause the xep says, execute defaults to "next"
chronosx88has left
lovetoxbut obviously a xmpp lib should not fill the var with "next" otherwise the UI doesnt know that there was no default action and no UI hint should be given
lovetoxeither way, after working this out now, i treat it only as UI hint client side
Tobiashas left
lovetoxand i dont default it to "next", because not set means no hint should be given
