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..."

Da würde ich gerne mal die Frage in die Runde stellen:

Hat sich schon mal jemand Gedanken gemacht, wie man ein soziales Netzwerk gestalten könnte, dass:
• Kommentare erlaubt, die dem VErfasser gehören,
• das Beschreiben fremder Social Feeds erlaubt und
• mit #ActivityPub UND #PubSub interoperabel ist?

Ich habe die Befürchtung, dass das auf eine Quadratur des Kreises hinausläuft.

@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`.

🌖 Kafka 效能驚人——我將選用 PostgreSQL
➤ PostgreSQL 在訊息傳輸場景下的實力驗證
✤ https://topicpartition.io/blog/postgres-pubsub-queue-benchmarks
本文探討在現代硬體日益強大的趨勢下，PostgreSQL 作為訊息佇列（queue）和發布/訂閱（pub/sub）系統的潛力。作者透過效能測試，展示 PostgreSQL 在處理不同規模的訊息傳輸時的表現，並與 Kafka 等傳統訊息系統進行比較。結論指出，許多時候 PostgreSQL 即可滿足需求，無需過度設計，避免導入不必要的複雜技術。
+ 作者的觀點很有啟發性，特別是關於「縮小資料」運動和 PostgreSQL 的復興。我一直覺得 Kafka 對於我們公司的小規模應用來說有點殺雞用牛刀。
+ 測試結果很有趣，尤其是單節點 96 vCPU 的部分。不過，End-to-end 延遲 853 ms 對於一些要求極低的即時應用來說可能還是太高了。
