Gregory's Server

#Smithereen update. I've completely rewritten the way user avatars are stored, both remote and local. I now cache the ones for remote users, and store them in 4 sizes and in jpeg and webp. This was a lot of work, and I now need to do the same for post photos. As an added benefit, "icon" in AP is no longer an array – some software didn't like that. As I found out yesterday, I've also forgotten that I need to send Delete activities when deleting posts. Now I do send them. And also, what kind of activity am I supposed to look for to know when someone's avatar was updated? Choosing the right language is apparently still a problem in 2019. My system language is English, but for some reason the captcha itself is in Russian. Because reasons. Задумался о том, что многие мои знакомые, включая айтишников, не понимают концепцию соцсетей с федерацией. Типичный разговор:— Нашёл работу?— Неа— А чем занимаешься?— Делаю децентрализованную соцсеть по типу ВК— Это как? На блокчейне?— Понимаешь как почта работает? Ну, что ты можешь из гугла отправить письмо в яндекс. Вот это то же самое, только протокол другой и вместо писем посты и лайки. А вы как объясняете?

@grishka @rf пытался объяснить принцип, что любой васян у себя может сервер поднять, но они между собой общаются, что есть альтернатива всем сервисам от ВК и инсты, до музыки и ютуба. Ноль реакции, никакого интереса. Не айтишникам, параноикам это не интересно. Пока Бузова или Ники Минаж не зарегается... I've completed "Secure Container" - Day 4 - Advent of Code 2019 https://adventofcode.com/2019/day/4 Why is JavaScript called that? The only thing it has in common with Java are toString and indexOf functions. Added support for displaying images. Now a question. I currently hotlink everything, including profile pictures. Downloading all media and keeping it eternally like Mastodon does seems to me like a terrible idea. But then hotlinking is also not ideal – Mastodon has images in different sizes internally while only serving the biggest ones through AP. I'm thinking about something in-between. A LRU cache with admin-configurable size maybe? So I just posted a reply to @Gargron's post from my #Smithereen instance. My first reply to someone else's post to contain an LD-signature. Then interesting things started happening! First, I received an onslaught of incoming requests for... something. I don't log GET requests. I knew Jetty is multi-threaded, but I didn't know it's this multi-threaded. Second, someone with a broken SSL configuration tried to follow me. I presume that's how you know you're now a proper part of the fediverse?  @grishka Yes, when you publicly reply to a post, and it has an LD-signature, we forward that reply to the parent's followers, so that people who click on the post get a more complete conversation. After countless hours of debugging, #Smithereen now finally supports linked data signatures! Could someone please help me making sense of LD-signatures? This RDF stuff drives me crazy. https://socialhub.activitypub.rocks/t/making-sense-of-rsasignature2017/347 I made my first unit tests today. I'll have to support the parts of JSON-LD spec I thought I didn't need because, well, I might end up needing them to verify LD-signatures. I did it! The JSON-LD algorithm spec was clearly written with something dynamically typed like JavaScript in mind. Implementing that in Java is pain in the ass and takes extreme amounts of instanceof statements to get right. But at least I now support those "reverse" properties no one's ever gonna use... Replying to something now adds a mention of both the author of the original post and of the reply you're replying to – so both those people get notifications. If you're replying to a reply, that second mention is actually visible. (side note: there are two kinds of mentions in AP, the one you put into the "tag" field which triggers notifications on Mastodon, and the one you put into the post content as a link that users can click on.) Seems like Mastodon only notifies you about a reply if the reply contains a mention. Addressing (to/cc) doesn't matter here AT ALL. So I guess I have to support mentions, no way around that ¯\_(ツ)_/¯ Now, there's a good question whether the mention has to actually be there in the post content or putting one in "tags" is going to be enough.  Verifying JSON-LD signatures doesn't appear to be the easiest thing in the world... #ActivityPub  |
