Hey,

Didn't have much time over the last few weeks, but I finally got time to finish at least a first draft of this.

I think the slides provide a good introduction into programming and for the next lecture, although it may still be a bit daunting. It may be a good idea to supply some more external materials, but it might just be an idea to have an additional document supply this to the lecturer.

As for the exercises, I feel like the tweedegolf GH organization should create the gists of them and provide links to the play.rust-lang.org with that gists. This way they don't need the development environment just yet. Please let me know what you think and which things can be improved.

I will just add some of the planning I did for the reworking of this module based on the meeting we had.

Essentially, we will divide the A0 (which we might want to give a different name now) into 9 topics. Starting from absolute zero to the point where they can build a simple calculator and know most basic programming concepts. I have also listed exercises that might be used for the topic.

Some notes:

• It might be interesting to add a small integration project where people do a bit of file manipulation. For example, a small HTML page generator would probably be very cool for the graphically inclined people. This would not require too, too much extra explanations.
• On some parts (e.g. Vec, Box, String, modules and CLI), I would want a minimal explanation to pragmatically use those concepts rather than actually fully describing those topics. For that, there are either already topics or it is not relevant.
• The reddit thread came up with the idea of just using modules to simulate multifile projects. I did not go with that approach here. Instead, I try to explain very basic concepts for CLI. This needs to be independent of target platform.
