Find myself having to make an unplanned road trip. Could fly. Don't want to. Could take the interstate. Nah. Could use a map. Nope. Think I'm just going to leave the house and drive backroads across the prairie until I get there some 1000 miles later. Sort of homing pigeon style.

2026-06-26T14:41:19Z

One advantage I've realized as an older student is having a ton of life-experience. So, when asked to write an essay on <literally any topic>, I can just start telling some tangential story about that one time I was out <doing something seemingly unrelated> and then somehow tie it to whatever is actually supposed to be discussed.

Later, when I get the grade back, the professor just writes "I wish I could have a coffee with you!" Ha!

This-/especially the "for fun" part. The last time I released something, I was mostly hoping to have some dialogue around it. "Here's this neat thing, let's play with it, see what happens. Have some fun." Instead, I get a bunch of people complaining about code style things (nothing of substance). Then some other shithead reimplements the whole project from scratch, commits a governance model as the first file, and that was the end of that (for me).

When fed back into buffalo's training, maybe all this writing would eventually drive buffalo into the singularity or some kind of other BS.

Thanks everyone for the kind words! This is by no means guaranteed--I have to take about 24 semester hours of classes, complete "field work" in HS classrooms, and eventually go through 10 weeks of student teaching. Plus there's the challenge of finding a job as a late career switcher. I like my odds (and math is a decently solid place to be as far as teacher demand), but I definitely don't think it's going to be easy.

At the very least, it's unlikely to be boring ;-).

Day 4 is done and I'm up to about 20 hours of effort now. I've made it through local variables and am preparing to start Chapter 23 on control flow. I can't even express how much fun this project is with the crazy tooling--or lack of tooling as the case may be. The "standard editor" indeed.

Okay. Day 3 is done. Made it to the part just before global variables are defined. So, tomorrow will probably be dedicated to all things variables. About 15 hours into the project now.

So, I've decided to do my own GC. Have now reached the hash table chapter. Rust already has its own HashMap. I could use that as a shortcut. Or I could try to roll with the book and make my own.

At the moment, the Hash in the book seems somewhat disconnected from everything else. And I don't recall Lox as having HashMap as a kind of value that you could use in user code. Somewhat inclined to use Rust HashMap<> for this until I run into a reason not to.

The book sets up linked lists of heap-allocated objects (in C). ...

The book sets up linked lists of heap-allocated objects (in C). Could be dicey trying to replicate that. Part of me says the whole problem could be avoided by slapping Rc<> on everything. But, that feels like cheating and not in the spirit of the overall affair. So.... hmmm.

Looks like the next few sections implement features that Rust already has (strings, hashmap, etc.). As instructive as that might be, I'm not going to reimplement all of that from scratch. At least I don't think so.

Ok, let's continue onward with scanning! I already continue this once before in Rust, but the implementation in the second half of Crafting Interpreters takes a different approach with ownership. So, I'll try to stay in the spirit of that as I go.

Well, I'm about 90 minutes into this project so far. It's, uh, freaky. But, I'm making progress. Translating C to Rust is a whole different game than translating Java. I don't really feel like doing all of this low-level byte oriented free/malloc business. No, I'll just use Vec<> and other nice Rust stuff.
