moodle-mod_webconferens - Half a billion people study here. The lesson can be private.

Moodle is where school already happens: lessons, homework, one login. About 150,000 sites, in more than 230 countries. More than 500 million people study and teach there. Millions of them are children. Web Conference is a live lesson on that same page. Faces, voices, a shared screen, a question a child types. That room can be encrypted. It should be. This is what we do: 100% encrypted, 100% private, for the students. What they say and show belongs only to the students in that lesson.

We’ve made a bunch of interesting changes to FastPubSub lately.

The overlay routing is getting smarter, nodes continuously measure path quality between regions, and the network can switch away from slower or degraded routes.

We also added a few simple live demos, so it s now much easier to see what the platform actually does:

Is AI still cheap or just temporarily subsidized?

AI pricing today doesn t fully reflect real cost.

Some reports and industry estimates suggest that real inference cost can be 5 10x higher than what companies currently charge, depending on model size, context length, and infrastructure load.

So the market is not really stable yet.
It s still in a growth phase, supported by subsidized pricing and scale.
And usage is already massive.

Most of you probably saw this report:
