Elixir and LiveView Pro (Pragmatic Studio Course)?

[nelsonic]

Hadn't looked at Pragmatic Studio Elixir in a while ... #41 (but have many books from https://pragprog.com ...)
Today @MikeRund mentioned the LiveView course: https://pragmaticstudio.com/courses/phoenix-liveview

Reading through the course description, we've covered 80% of it in our free/open tutorials
& ultra-documented projects and in several cases vastly exceeded them!
e.g:

1. https://github.com/dwyl/phoenix-liveview-counter-tutorial
2. https://github.com/dwyl/phoenix-liveview-stopwatch
3. https://github.com/dwyl/phoenix-liveview-todo-list-tutorial
4. https://github.com/dwyl/phoenix-liveview-realtime-cursor-tracking-tutorial
5. https://github.com/dwyl/phoenix-liveview-chat-example
6. https://github.com/dwyl/imgup > Build It! (File Uploads to S3)
7. https://github.com/dwyl/mvp > BUILDIT.md

With that said, there are areas where the course goes into more depth in explaining key concepts
and also covers others we would like to cover but haven't had time to yet.
e.g:
5. Dashboard - we would like to build one with LiveView so keen to see how they're doing it. 💭

When we viewed the page, we were presented with the discount code friendsinportugal:

@MikeRund if once you're done with our basic LiveView tutorials, please LMK if you're still keen on this course. 👌

I think what makes it appealing isn't just topics themselves which are of course very thoroughly covered in the text-based tutorials on here, but the combination of animations, concept discussions, code and discuss tutorials and exercises. I feel like the medium of an online course offers more opportunity to solidify understanding. For those reasons I am super interested in completing the courses, but am still very happy to continue on with the current plan!

I should use a VPN...😥

I was tempted by this one: https://phoenixliveview.com/#plans

Cheaper.

@ndrean also looks good and more in-depth on the inner-workings of LiveView. 👌

@nelsonic I can only say that I follow the creator on Twitter, https://x.com/ThatArrowsmith and he seems good and interesting.

Then, @MikeRund , I would just start https://adopt-liveview.lubien.dev/ . This is free and very good. Then you can come back later, for things like Ecto, Streams, async...

The Education and Uptake Working Group has developed and evaluated custom GPTs to facilitate the introduction of Erlang, Elixir, and OTP to individuals with limited or no prior experience in these technologies. These GPTs are not intended for collaborative programming or assisting professional coders.

Tested:

• "can you explain how to setup a dynamic supervisor?"
• "can you explain assign_async"

Saša Jurić's 2019 talk "The Soul of Erlang and Elixir" is available on YouTube and he released the repo:

I believe its worth watching again(?) with this companion repo

Supervisor strategy:

You can start children using:

• the :one_for_one strategy, which means that the Supervisor will restart only the crashed GenServer process and won't touch the remaining ones.

• the :one_for_all strategy, which would instruct the Supervisor to terminate all remaining processes and then to restart all processes, including the terminated one.

• the :rest_for_one strategy, which means that the Supervisor terminates all process that come after the crashed process in the list of children and then restarts the terminated processes, including the crashed one.
