AWS has the Monday morning blues. Half the world is struggling to operate because their SaaS is down. At least I'm back to running a local dev environment now. In my Lambda days I'd be twiddling my thumbs.

So after a two and a half year stint as a full time Node engineer, I'm back coding in C#, but now on Linux with Rider as the IDE. It feels like a warm old familiar place. Rider is a pretty good experience so far. JetBrains certainly know how to build an IDE.

Several years into using z-shell I discover that ctrl-XE opens the current command in nvim (or whatever you've got set as your default editor). I wish I'd known this before.

So I think I get the memory allocation model in Rust: everything goes on the stack, unless it's some kind of smart pointer like Box, or Rc, or also Vec and String. Just been reading Ch 15 of the Rust Book: doc.rust-lang.org/book/ch15-00...

Not a huge fan of the Rust closure syntax. I imagine there's a good reason for using pipe instead of brackets for the argument list. I suppose at least it makes it clear that this is a closure rather than a function.

I grew up in a commune. I had a great time as a kid, but I think it's a fundamentally unstable arrangement. The reason you see so few of them is because they rarely last.
I love this. It's crazy, pretty much everyone I know, everyone I've ever talked to about it, craves some sort of more communal living. *Everyone.* And yet the US offers almost no models -- you have to build it from the ground up.

The Rust debugger in Zed is pretty intuitive for anyone who's used the C# debugger in VS. I've only used it on really simple examples so far though.

It's really interesting how Rust makes you think about memory allocation in cases that would never occur to me in C#. For example, If a function has a function return value it has to be boxed because you can't return stack allocated memory as a return value.

Interesting how Rust provides the `?` syntax as a kind of poor-mans `do` notation. Can one make it work with one's own types I wonder?

Unexpected mini-feature of Rust that I haven't come across in any other language: You can reuse a variable name in a new variable declaration and the compiler is fine with it. If it's in a new inner scope then the outer scope retains the original value too. I'm not sure I like this.

Very interesting blog series from @paullouth.bsky.social on higher kinded types in C#. He's kinda (see what I did there) made an `M a` out of a `K`.
It actually comes out reasonably smooth (but agreed that it should be in the language).

Building greenfield software is certainly fun, but it's actually quite a rare treat for most professional software engineers. The vast majority of work is maintaining and extending large legacy systems. If LLMs are going to help, very large context windows are a essential.
