Redis Pub/Sub drops messages when consumers disconnect. Swap it for Streams + Consumer Groups: append-only radix tree, offsets, ACKs, PEL per group. https://www.valtersit.com/vault/migrating-ephemeral-pubsub-to-durable-streams-with-consumer--646030/ #redis #streams #pubsub

Codex написал рабочий код, но не закрыл задачу: как меняется мой процесс разработки
Я всё меньше пишу первую версию кода сам. Раньше backend-задача чаще начиналась для меня с реализации. Сейчас я могу описать её Codex, получить diff и уже от него идти дальше: разбираться в коде, проверять поведение системы, находить недостающий контекст и отдавать задачу на следующую итерацию. Недавно этот процесс хорошо проявился на интеграции между несколькими сервисами. Codex написал рабочий код, но end-to-end задача осталась незакрытой.

Publish-Subscribe (pub/sub) is a messaging pattern that decouples publishers from subscribers through a broker. Publishers send messages without knowing who receives them; subscribers get only messages matching their interests.

New progress note available (after 3 years during which I posted here on ActivityPub instead of on the blog):
https://www.goffi.org/id/libervia-progress-note-2026-w16-ooph
I'm talking about current work on installation/configuration simplification and the new forge, focus on web frontend and redesign and work done with current metadata reduction and serverless XMPP (Tor, contacts e2ee, new pubsub implementation).

I've just pushed a new pubsub implementation (basically a reimplementation of SàT/Libervia Pubsub on top of Libervia Backend).
May not sound exciting like that, but it's a major thing for many reasons, I hope that I can find time to blog about that tomorrow.
Also it implements XEP-0496 (Pubsub Node Relationships) and XEP-0499 (Pubsub Extended Discovery) which means node hierarchy, useful for things like forums.

Kafka: Queue & Pub-Sub Together 📨
Queue (1-to-1):
1 consumer group, consumers = partitions
Each message → 1 consumer onlyPub-Sub (1-to-many):
Multiple consumer groups
Each group → all messagesTraditional systems need separate tools.
Kafka does both natively! -
Server-Sent Events Beat WebSockets for 95% of Real-Time Apps (Here's Why) - DEV Community
"Everyone defaults to WebSockets for real-time features. Most shouldn't.
The reality: 95% of "real-time" applications only need server → client updates. Chat notifications. Live dashboards. Stock tickers. Log streams. AI responses.
WebSockets give you bidirectional communication. But bidirectional comes with a tax: complexity, resource overhead, scaling challenges, debugging nightmares.
Server-Sent Events (SSE) do one thing: stream data from server to client. They do it brilliantly. And for..."

Broadcast Channel API - Web APIs | MDN
"The Broadcast Channel API allows basic communication between browsing contexts (that is, windows, tabs, frames, or iframes) and workers on the same origin.
By creating a BroadcastChannel object, you can receive any messages that are posted to it. You don't have to maintain a reference to the frames or workers you wish to communicate with: they can "subscribe" to a particular channel by constructing their own BroadcastChannel with the same name, and have bi-directional communication between a..."

@visionaire genau heute las ich xkcd mal wieder.
Da macht sich also wieder jemand Gedanken wie man Social Media neu erfinden kann.
Immerhin wurde #pubsub und #mastodon als Nische erwähnt.
Schade das nicht erwähnt wurde WARUM man was neues braucht und nicht das #fediverse besser promoten kann

Libervia CLI Tip 16:
You need to modify many pubsub items? `li pubsub transform` is there to help.
It uses an executable (e.g., shell or Python script), gives it each item as input, and replaces it with the returned item. Use `DELETE` to retract the item, and `SKIP` to ignore it.
Very handy if you, e.g., moved an URL and need to update all your blog posts, change a tag, or do any kind of massive modification.

Libervia CLI Tip 15:
When publishing a blog or other pubsub based feature, the item ID is often used in the URL when it is rendered for the web (e.g.; Libervia or Movim use something like `https://…/blog/<user>/<item_id>`).
It is then important to have a user-friendly item ID (e.g.; `title-of-my-publication-abc123`), which is usually done by the software from the title.
If you want to change it, you can use `li pubsub rename`.

ActiveMQ Artemis vs Apache Kafka
Добрый день. Сегодня мы поговорим о двух мощных технологиях для асинхронного обмена данными — ActiveMQ Artemis и Apache Kafka. Мы разберемся, что они из себя представляют, как устроены под капотом, и главное — в каких ситуациях стоит выбрать одну, а в каких другую. Наш план на сегодня довольно насыщенный. Мы начнем с того, почему вообще все пришли к асинхронному общению сервисов. Затем подробно разберем ActiveMQ Artemis — что это и какие задачи решает. Заглянем в его техническую архитектуру, чтобы понять источник его производительности. После этого мы кратко вспомним основы Apache Kafka, чтобы затем перейти к самому интересному — детальному сравнению. Мы составим четкие рекомендации, поговорим о нагрузочных характеристиках и подведем итоги.
