Lately I've been making a few tutorial videos to address some 
fundamentals and practical code examples in projects that run with repos 
you can explore and hack on.

Network services: Telnet chat server
A two-part example of a multiuser network application in its minimal 
stages to show how such a thing can work first as a broadcast/echo 
service and then with channels, usernames, and a limited permission 
system that is small enough to understand the components of with a 
minimal of code reading.

Here is a blog post with both videos linked and an explanation of each.

GUI coding: Tetris in Erlang
This was a lot of fun, but took a bit of time to explain exhaustively so 
it turned into a 3-video series. I make sure to talk through the commit 
history so you can play with each commit stage locally and understand 
the diffs without too much exploration.

There is some other stuff as well, but you are the target audience for 
these so I figured I'd link them here as some others have found them 
helpful. I really need to do a "wxErlang from the ground up" sort of 
video but haven't decided a good way to structure that just yet. A 
little informal group of other coders and I are considering expanding 
the chat example service with a GUI client with some extra feature 
extensions (like launching multiplayer games, communal whiteboard, image 
chat, etc.) as an example and a plugin playground newcomers can play 
with and study for ideas but we haven't found the time just yet.
