Title: Julia Language on WebAssembly: Our Wish List and Experience So Far Speaker: Jeff Bezanson—Julia Computing Summary: Last year a proof-of-concept WASM port of the Julia run-time was…

In this presentation we will review, generators which lead into the last major topic of the course (coroutines). Once again, this will involve a lot of visualization.We also start off this…

While generators are coroutines, the communication only goes one way: from the child to the calling parent. In this video we show how to reverse this communication, passing down information from the…

Generators take iterators as input, but they also produce one as output. In this video we show how to chain iterators together, doing complex operations on our data.

In this video we talk about two very famous generators: map and filter. We show how to use these to replace writing code with a for-loop.

Now that we know how generators work, it is time to write our own. In this video we show how easy it is. We just take out experience with the accumulator pattern and replace the accumulator with a…

Making iterator classes is hard. In this video, we show an alternative, allowing us to write the iterator as a ‘function”. This requires the addition of a new python statement, the yield…

In this video, we show how to make our own iterable and iterator classes. These are actually tightly linked, and you need one to create the other.

We are familiar with iterables, types that we can use in a for-loop. In this video we introduce the iterator. This is a type that can be used in a for-loop, but we can also manually step through the…

Game applications (and graphical applications in general) can get pretty complicated. In this video we talk about how to break up your code to make it more readable and more manageable. In some…

The big difference between a game and a movie is the ability to respond to player input, be it from a mouse or a keyboard. In this video we show how to us the tools provided by the GameApp class to…

In this video we introduce the GameApp class, which is a class written by your instructor. In the last assignment you will be creating a subclass of the class to run your game. This video highlights…

The while-loop that drives the game is hidden. This is going to create some interest challenges, particularly when you need variables that carry over from animation frame to animation frame. In this…

Our last presentation on classes reviews the issue of typing, and why this has become much trickier with the introduction of subclasses. This is the last material covered in the second exam.The…

in this presentation we review the Python data model, showing off the various operators we can define in Python. This is an area where Python is much more advanced than older object-oriented…

When we were recording the video on custom error types, it ran quite long. So we decided to break it up into a second video. In this video we look at a slightly more complicated error type. We also…
