XSF Discussion - 2019-06-12

lovetox, I cannot join jdev@ because jabber.org has DH keys which are too small to be accepted by my server

white is 255,255,255, so inverting gives 0

Dumb question about the whitespace thread on standard@, I've read this: "it's more efficient for battery usage to use push notifications", but Google also has to maintain a TCP connection to push these notifications right? So they are eventually running into the same issues as us? How is that more efficient ✏

pep.: I think this story of push notifications saving traffic originated from them being used as an alternative to crappy (HTTP) polling. The remaining point I see is that with push notifications, the OS can freely kill the app on resource shortage.

Plus maybe a little traffic optimization after all, if you take into account that TCP keepalives or thelike (I think theirs weird stuff done on mobile) are per connection.

But in general you're right, I think.

I would /assume/ (very possibly wrongly) that they're smart enough to not go spinning the radio all the way up for push notifs.

Kev: I'm not sure this is how baseband modules work.

So yes, it's a matter of keeping a single TCP connection vs one per app or even long polling / periodic polling by each app

Also google has done significant work on making that connection stable, even under adverse conditions like very short NAT timeouts

(they are measuring them and maintaining per network keep alive intervals)

Ge0rG: Well, whether you can control the baseband or not (Apple presumably can, at least), you can make your push notifs small enough to avoid significant wakeups, no?

But I'm working entirely on intuition here, no clue what I'm talking about.

Kev: well, yes

Being smart about scheduling could help, in theory

I don't think there are significant delays in delivering push to Android. Except for the trash calendar app on my Samsung phone, where all notifications come a day late

iirc Samsung have their own push thing, or used to

So you have to go through Google and then Google goes through Samsung? :p

Or you skip Google and have to support two APIs ?

Haha

I have no idea why it doesn't work properly. It was perfectly on time on LineageOS on my previous phone

pep., batching the push notifications and takign the devices sleep cycle into account is the only minor argument I am able to come up with, but besides that, an XMPP connection could be as efficient as an google push connection

but google does obviously neither for high priority FCM pushes, only probably for normal priority messages

why jingle has only global tie-break error but not per content? What if we have multiple <content> elements in a request and only one of them is <tie-break>. Basically the same for <reason> which may be different

rion, potentially no particular reason and just something the authors did not consider. From how I understand jingle, having per content tie-breaks sounds sensible

I'm implementing transport-replace in Psi right now. It's mostly finished. But these problems with tie-break and necessity to send transport offer twice make me frustrated.

Can there be fulljids in the roster? (that is, a fulljid I'd be subscribed to)

pep., iirc yes, you can (in 6121, possibly not 3921), but don't expect it to work how you want, you can't subscribe to a full JID

Are you sure? I thought it was bare JIDs only

Zash, I can find no such restriction

I also remember a discussion on that topic, but none of the conclusions.

To go back to this morning, the argument for push notifications over a TCP session comes down to that if all the pushes go through the same channel, this can be optimized in terms of combining radio activity. But I think it's a sketchy argument, given you'd have to introduce latency and things in order to combine them anyway.

guys, what do you use to edit XEPs? To preview them quickly

rion: sam build a inotify based make target that would build the html every time the xml changed

I use something similar like that

rion, I use a texteditor and my typical arrow-up-enter workflow

with `make build/xep-1234.html`

`:make`

ok. got it. thanks.

lol jabber.ru sends russian text on the IBR form

no idea what they want me to put into the field

lovetox, I’m not in jdev@ because I can’t join due to Server-to-server connection failed: Connecting failed: ssl handshake error: dh key too small ✏

yeah i read your message

ah ok

you’ll have to live with that until jabber.org is fixed

lovetox: try to type some russian =)

thanks for the hint with background, i though for some reason 0,0,0 is white :D

:)

yeah, the jclib implementation is historically grown and a bit of a mess

works good now for me, gajim has now also default avatar generation

\o/

awesome

Пользователь = username Электронная почта = email Телефон = phone

I need to get the text on semianon vs. nonanon in 392 and then it can be advanced IMO

thanks rion i found my old account just now and rememberd the password

(specifically, in a semianon room, you SHOULD use the nickname, even if you have privileges and can see the real JID; in a nonanon room you SHOULD use the real JID)

yeah although this is bothersome to implement

lovetox: so russian FSB won't follow you since phone number wasn't required previously

my contact object does not have the information about the room settings the contact is in

:D

rion, yeah because anyone puts in the real number there :D

lovetox, yeah, transferring that information will be a tad annoying

but it might be good to do that anyways, considering that you don’t want to accidentally leak a real JID you only know because you are a privileged member of a room

so carrying that information around might be good to present that bit ("you only see this because you are a moderator, tread carefully") in the UI

lovetox: speaking of old accounts. There was a bunch of spam bots on Gajim.org recently. Do you have IBR enabled? Is it even meant to be a public server?

> Accounts not used for more than 1 month are destroyed. > To register an account, go to this URL : <a href="https://gajim.org:5281/register_web" style="color:#000080">https://gajim.org:5281/register_web</a>

please just send them to me, i will forward it to asterix to delete them

mm now I have an account on gajim.org

and yeah register on gajim.org is enabled, but i will question if this is necessary

as the server is not maintained for users really

So maybe somebody broke the captcha? But it was only two bots, that's not the typical pattern. They come in hundreds normally

there is no captcha, just a "what is 7 + 9"

probably very hard for bots

I don't have the JIDs here right now, you just weren't online for a long time

yeah i dared to go on holiday 2 weeks

lovetox: you need a mobile xmpp client! 😜

hm im still evaluating what the real price of having a smartphone is, could take a while

I’m interested in your calculations

$ expr $(wget -qO- https://gajim.org:5281/register_web | grep -oP '(?<=What is )[^?]+') 7 $ expr $(wget -qO- https://gajim.org:5281/register_web | grep -oP '(?<=What is )[^?]+') 5 $ expr $(wget -qO- https://gajim.org:5281/register_web | grep -oP '(?<=What is )[^?]+') 3 $ expr $(wget -qO- https://gajim.org:5281/register_web | grep -oP '(?<=What is )[^?]+') 3 $ expr $(wget -qO- https://gajim.org:5281/register_web | grep -oP '(?<=What is )[^?]+') 7 $ expr $(wget -qO- https://gajim.org:5281/register_web | grep -oP '(?<=What is )[^?]+') 15

but I love this captcha anyway :)

thanks, forwarded

Gajim makes XMPP great again

user registrations just in May

https://lagaule.org/munin/static/dynazoom.html?cgiurl_graph=/munin-cgi/munin-cgi-graph&plugin_name=localdomain/localhost.localdomain/prosody_users&size_x=800&size_y=400&start_epoch=1525803610&stop_epoch=1560363610

=)

Why have open registration?

I use the simple match question plugin in Psi for a while for subscriptions. Bots are smart enough to answer the match question for a while now

does jabber.ru have some fork of ejabberd

they report version 3.2.x

or is it that old

they suffer from an older bug i reported to ejabberd

not respecting the stream xml:lang

That's an old version of the Business Edition.

Which is based on even older code of the Community Edition.
