The Crust of Rust episode on Rc/RefCell/Cell and Arc/RwLock/Mutex is now up — get it while it's hot! We covered smart pointers and interior mutability, and even did a quick-dive into UnsafeCell and the Drop Check 😮 youtube.com/watch?v=8O0Nt9qY_v

Several of you have asked me for a Crust of Rust on smart pointers (Arc/Rc/Deref) and interior mutability (RefCell/Mutex/Cell) in , and I think it's about time. Let's do a stream on Wednesday at 8:30p UTC (everytimezone.com/?t=5ee95d00,) as usual. Come one come all! 📺 🦀

Yesterday's Crust of Rust on iterators and trait bounds is now on YouTube, fresh out of the oven (literally; my apartment was ~95°F at the end). We re-implemented Iterator::flatten, including the DoubleEndedIterator parts! 🥧 youtube.com/watch?v=yozQ9C69pN

The second Crust of Rust video is up! We went over how to implement the vec! macro, including how to get it to efficiently pre-allocate memory for the provided elements. Get it while it's hot! 🥧 youtu.be/q6paRBbLgNw

The Crust of Rust mini session on lifetimes seems to have been helpful, so let's do more! I'll cover declarative macros (macro_rules!) on Wed at 8:30p UTC (everytimezone.com/s/2761f055). As before, it'll assume you have some
experience already, but anyone is welcome ❤️ 🥧 Just like always, the stream will be live on youtube.com/c/JonGjengset/live on twitch.tv/jonhoo, and I'll upload it to YouTube after :)

The recording of my first mini session is now up! We covered lifetime annotations through a real code example, and people seemed to follow along and understand why the lifetimes were needed and how they worked 🎉 Watch it at youtube.com/watch?v=rAl-9HwD85.

In about 6 hours, I'll do a shorter and more beginner-friendly stream on multiple lifetimes, strings, and some generics. As usual, the stream will be live on twitch.tv/jonhoo and youtube.com/c/JonGjengset/live, and I'll upload it afterwards. While it'll be *more* beginner-friendly than my usual streams, it won't be *introductory*. I'll assume that you've read the Rust book, and that you have written some Rust code. But as always, anyone is welcome, so stop by even if just to say hi ❤️

Recording of the Noria stream is up! I think it went well — people seemed to follow the system design and the bug we ended up partially fixing, even though it was quite technical! If you're stuck at home and craving some research-y , give it a try: youtube.com/watch?v=kiMUI0y91Y. You can find the project website with code, papers, and other related material at github.com/mit-pdos/noria

It seems like there's a lot of interest in a live-stream where I work on Noria, my research database written in . So, I will do one *tomorrow* at 8:30pm UTC (4:30p Eastern; everytimezone.com/s/c34ddd6c) on YouTube and Twitch as usual. Come do research with me 🤓
