There should be some way to deref types in pattern matching. I.e. this struct has a vec, and I only want to match on those structs whose vec matches some slice pattern

Not sure what other people’s conclusion has been with all the discourse on consciousness but I’ve decided to become a philosophical zombie just so I can avoid talking to people about it

When I was younger I was kind of upset that nerd media became the domain of insanely hot people, but now that I'm older I'm thankful because nerd media is shit, and now I can call all those hot people nerds.

I had this really clever atomic pointer thing going on that made my Gc lock-free. Turns out, a lock is significantly faster

Somehow this is both more and less than I expected this to cost

At least, this is what I recall. I'm not going to look this up to verify whether or not it's true

Indeed, they are technically beer. This is why they became so popular so quickly - they developed a brewing technique that allows them to be classified as beer, and thus avoid the more expensive tax associated with combining vodka an seltzer

There's a bug here that I spotted after posting (the second clause of the first if should be not) but it doesn't change the result

I normally do not mind it all, but occasionally you do hit a corner case with the Rust borrowchecker and you're best option is just trying random permutations until it accepts it. For example, almost all sensible compactions of this function failed, and this is what I was left with:

The most interesting thing about me, the thing I bring up to literally everyone I meet, is that I have a full size washer and dryer in NYC. Not one of those compact ones. Fully size

I remember hearing the term β€œawesome sauce” in what… high school? I thought it was pretty cringey then. I’m 31 now

Not really the point but how much ketamine must one do to unironically say β€œweak sauce” in the year 2026?

Prompts - scheme-rs scheme-rs: embedded scheme for the Rust ecosystem

Scheme-rs has algebraic effects! We just happen to call them prompt handlers scheme.rs/Standard%20L...

scheme would be so ahead of its time if R7RS large was released ten years ago with prompt handlers

I don’t get why people don’t like this typesystem… don’t they know it’s the farthest vertex on the lambda cube?

The craziest thing about programming in C that I can’t believe we used to do was use types like ”char”, β€œint”, β€œlong” and had no idea how big there were
