Hello everyone. I built an MQTT diagram editor/simulator.

You draw on a visual canvas by dragging brokers, clients, topic lists, and bridges to the canvas. In simulation, messages actually flow, latency and packet loss are configurable, and the validator flags bridge loops and unreachable topics before you run anything.
The same diagram generates Rust client code, broker configs, and AsyncAPI specs.
All free.

Having built a solution around mosquitto auth plugins, working out how to migrate to something new, I need to reuse the same underlying mongo db that has the credentials stored in it.

Both of the plugins could work with the existing database, but I don't think there is a current plugin that supports the latest mosquitto

Best thought so far is to move to EMQX and make use of the HTTP auth and write a little server to handle the auth look up

#mqtt

hmm, does mosquitto not support bridge mode with MQTTv5?

Trying to bridge from EMQX to mosquitto 2.1.2 with MQTTv5 and bridge mode enabled and it fails with "protocol error"

Turn the protocol down to v3.1.1 and it woks

#mqtt #mosquitto #emqx

Quand la surveillance s’installe sans bruit

La surveillance ne porte plus exclusivement un uniforme ni une caméra apparente.
Elle prend désormais le visage lisse des objets du quotidien.
Des lunettes IA aux babyphones, jusqu’au Wi-Fi capable d’inférer des gestes et des présences, une même bascule silencieuse est à l’œuvre.
Nous n’entrons pas dans un monde plus visible, mais dans un monde où l’on peut savoir sans forcément voir.
Et c’est peut-être là que commence la vraie rupture : quand la captation devient ordinaire, discrète, presque acceptable.
