A short demonstration of the Australian COVIDSafe app and how its Bluetooth connectivity is affected by putting the app in the background.
A fun quirk of TCP/IP is that you can create a connection without a listening socket. In this video we briefly review how that works, then write a Rust program to trigger the unusual behaviour on real Linux hosts. Code: [https://github.com/thom...
A gentle exploration of building a identd for Linux using async/await and tokio 0.2. This part demonstrates halting an await after a configurable time limit, both using tokio's timeout() helper and with the select! macro from the futures crate.
Rust libraries come in a variety of API styles and futures are just one option. In this video we compare and contrast four styles from three crates: 1. Synchronous blocking functions (websocket) 2. Single thread reactor (ws-rs) 3. Non-blockin...
A discussion of how futures are given to an async executor and later dropped. Examples of cancelling an Interval stream by erroring out of for_each, and by selecting against another future.

Experiments with tokio’s lines() function, fold(), and a custom multi-stage future with inner futures and the try_ready macro. With this episode, we are now up to four sub-optimal ways to count the number of lines in a file.
