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...
The most difficult fields to validate are so called free text fields", as the most frequent stereotype of web application input valiation goes, becomes even more complicated when the free text contains multi-language Unicode. Unicode is indeed com...

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.
I play around with a standalone future to see how the tokio executor’s polling works in practice. I then adapt a callback-based API to work with futures, including a full implementation of a leaf future that transitions from NotReady to Ready.
Two-legged gait developed by a model-based reinforcement learning controller after ~30 min of training.
Undulating gait pattern developed by a model-based reinforcement learning algorithm after 30-50 minutes of training.
Simple PWM system for controlling pressure, here used to 'break in' a silicone baloon. The input pressure is 1 bar. First I set the pressure to 1.8 bar to expand the baloon as much as possible, then I immediately decrease it to 0.5 bar, and ...
