The first day of the Hackathon at #IETF124 in Montreal is coming to an end.
We implemented the relatively niche feature of XEP-0444: Message Reactions that allows channels or group chats to restrict the type and number of emoji reactions users can do.¹This brings us a step closer to advancing and stabilizing the XEP. We didn’t want to do that before, since we aim to have complete implementations before requesting a Last Call.

@daniel Oh cool, did you implement a "restricted emoji picker" in Conversations? I only implemented "1 emoji/message" in @gajim
For groupchats I followed the spec, but for 1:1 chats lovetox did not want to rely on anything resource-related (client disco features/caps). I added the restriction form at the "server" (=gateway component) level, by adding a `scope=domain` field. It may be worth an extra sentence in 2.2 of the spec?

@daniel @nicoco @gajim I'm not sure we need to announce a scope, I would usually expect restrictions to apply to all "sub JIDs" (that is, it applies to full jid if disco'd on bare JIDs and on bare JIDs when disco'd on domains).
That said, the main issue with announcing it on the domain is that many clients don't disco their peer's domain (also typically not the bare JID) and it would be weird to disco all domains of all contacts just for the purpose of reaction restrictions.

> it would be weird to disco all domains of all contacts
I think the reasonable use-cases are MUCs and gateways. If you use a gateway, you probably have its disco cached somewhere. It makes sense to check for restrictions there specifically if one wants a client that integrates nicely with gateways. It should be "almost" free if it is already implemented for MUCs, I think? -

Sure, if a service was disco'd before and I thus have the data available locally, I'd use it. For what I know, most client implementations only ever disco their local server, bare JIDs of MUCs and full JIDs for which they got a caps string in their presence.

If you want to use a gateway, you likely need to disco it to look for registration mechanisms and adhoc commands you can use on it. I can't speak for all clients, but gajim disco JIDs in your roster, and if you have a slidge-based gateway that properly advertise its gateway type, it also uses that to add an icon to the avatar. -

Il rito della Finanziaria
@anarchia
Cambiano i governi ma le finanziarie rimangono. Rimangono uguali a loro stesse: un miscuglio di tagli e incentivi di varia natura, per lo più alla produzione, che servono a rientrare nei parametri dell’austerità europea e a mantenere immutato l’assetto politico...Vedi l'articolo

@ribby qualcosa su proxmox?
-
@demofox anyways on the reversing a linked list challenge, I want to say that I asked them what the requirements would be eg context of its use and the interviewer was like :) no just come up with something impress us :) :) but I might be misremembering as that was ~10 years ago.
-
@demofox tbh it was good to have bombed that one because it helped me realize I should brush up on my c++ before applying for any of the jobs I actually wanted
-
@demofox a long long time ago last time I was unemployed and job hunting I had an interview with apple and they asked me to reverse a linked list. so I said I'd use whatever library function is available. interviewer said no, pretend there isn't one. then I gave them a naive O(N) solution and then the interviewer said it was no good because it used recursion and thus too much stack memory and what if the device didn't have enough memory?!
-
@shanecelis lol I laughed in real life
-
@demofox INTERVIEWER: Can you reverse a string?
ME, pulling a string from my pocket: Of course.
-
@demofox Oh, that's easy. Just perform a complex valued DFT of the byte values twice in a row. It's O(n log n) so it's even *relatively* efficient.
