↳ In-reply-to » (#6uo24ta) @chronolink Replies are not part of the original twtxt format. They were added later as an extension by Yarn.social: https://dev.twtxt.net/doc/twtsubjectextension.html (only the section “Machine-Parsable Conversation Grouping” is used these days)

Hmm, @prologic@twtxt.net / @lyse@lyse.isobeef.org: Should we remove the section “Traditional Human-Readable Topics” from the spec? Or mark is as deprecated? I haven’t seen this being used in the wild for years. 🤔

@prologic@twtxt.net @ullarah@txt.quisquiliae.com I often see messages longer than what the textbox limit is, isn’t it limited by the maxlenght?, I found a workaround by writing from Goryon on mobile, on PC i can simply change the limit with the inspector but isn’t it there for a reason?

I too would like to express a bit more if possible, especially if i have to refer to users and link URLs and images for example, having a limit that isn’t too much of a limit is kind of pointless i think. 🤔

↳ In-reply-to » For instance I normally use the same RSA key/pair on all my workstations for my ssh client, because that's me, no-matter where I am. The only exception to this rule is I usually create a separate key for any "work" / " company" I am a part of.

@prologic@twtxt.net I have seen single use keys that are signed by a central PKI .. Keybase has one that uses a chatbot to generate the keys on the fly.

It just comes down to your threat model :)

@prologic@twtxt.net Re: Chat system, What if the base specification included a system for per-user arbitrary JSON storage on the server? Kind of like XEP-0049, but expanded upon. Two kinds of objects: public and private. Public objects can be queried by anyone, private objects cannot and must be encrypted with the user’s private key. Public keys could be stored there, as well as anything else defined by extensions. Roster, user block list, avatar, etc.

↳ In-reply-to » Another day, another 5m outage 🤬

@prologic@twtxt.net

Not sure if Starlink satellites are in orbit around/over Australia yet, but I wouldn’t go with that option anyway due to the latency alone.

I believe it is being trialled in some places in Aus already. I will admit, I’ve been signed up for the beta for a while and it’s supposed to be coming to my area sometime in 2022, though that may be delayed due to the chip shortage stuff.

I think the latency is supposed to be 45-60ms on average, which while not as good as fixed line obviously, is leagues better than old fashioned high orbit satellite broadband which is about 600~ms.

@prologic@twtxt.net, who calls me name when I am busy profiting? 😂 In a less serious note—because nothing is more serious than making profit, of course—yes, it seems your avatar issue has been fixed. I am kind of sad, I looked forward each day to see which random one was going to show. LOL.

↳ In-reply-to » @quark Fixed the "Enter" key issue, sorry about that. I'm dumb 🤦‍♂️ Also I hate Javascript! 🤬

@prologic@twtxt.net you be the man! I can’t remember the last time something gave as much troubles as this. The mention and the way to handle images are two things that have stuck in my head. Hopefully this is the last time there is an issue with this one! 🤞🏻
