Just saw this now. The two aren't remotely in conflict. The _rewrite_ (from zig to rust) almost certainly didn't result in the performance improvements they're claiming, because rust and Zig are roughly equivalent in that r

At this point, I find myself hoping for a AI triggered mass casualty event that's not at a civilization destroying level, because that seems like the only thing that might actually stop these people from driving our entire species off

The announcement also makes it very clear that 1.4 isn't just a rust port of 1.3. Rust is my favorite language and it can be a bit faster than other systems languages in the right circumstances (because the compiler can make optimiz

I think that the bun rewrite actually supports the oppposite conclusion in a lot of ways: 1. The resulting code was of pretty low quality. Others that bothered to put it through Miri and the like found many soundness issues, but my perso

Do you think the LLM reads every page on the internet before generating your answer? Of course not. What happens is that it use some sort of ranking algorithm to pick the pages that are most likely to answer your query and reads *them* (a

Google (as it originally) existed wasn't a source of information, it was an *index* of it. You were trusting google as a source for {search_query}, you were trusting the links it gave as a source (based on your own evaluation). LLMs

Sensible companies don't do a lot of stuff Meta has already been caught doing - sometimes with real consequences (but never enough to actually deter them, of course) - in the pursuit of more data.

In that case, you'd branch into a separate function/block that runs the calculation. Sure, it's slower than a simple array index to find a coefficient, but you're only incurring that cost when you actually need it and i

It won't do that for free, companies (and open source maintainers) will have to pay for the tokens used finding vulnerabilities in their own software. That increases the cost of releasing the same product/feature/amount of c

Wouldn't that explanation predict that lower ranking employees would be more impressed with AI than higher ranking ones? Because what we actually observe [0] tends to be the opposite. Executives are the most bullish on AI, followed b

LLMs are very impressive. Five years ago, the idea that we'd have software that you could ask - in English, mind you! - to rewrite an entire server side JS runtime and you'd get something which even kind of worked was squarely in

I think 2 is a reasonable concern (and one which has solutions in rust async/await tokio, as FridgeSeal points out). I'm not sure about 1 though. I think having a rough idea what part of your programs are computationally expensi

I didn't say they made a good, safe port. I literally said the opposite ("especially if you're flexible about actually upholding rust's rules"). You can get a line by line port to compile by just wrapping the part

To be fair, you can throw an Arc<Mutex<_>> or Rc<RefCell<_>> at it if you're starting from something that has multiple "mutable borrows", but that adds runtime cost and complexity.

You can also do one by using `unsafe` liberally, especially if you're flexible about actually upholding rust's rules (as the bun team just did). But either way, you're still stuck with a code base that's going to need e

Except that writing safe rust often requires designing the architecture around rust's ownership model, meaning a file by file, line by line translation doesn't necessarily leave you much closer to safe rust than you were at the st

First, we're talking about a massive rewrite of complex software project which no one has fully reviewed and which the people most familiar with the code base (the bun maintainers) aren't even qualified to do so. As such, the iss

It's funny, because editor choice is also an analogy I use, to argue for the exact opposite conclusion. Your hypothetical developer wouldn't be using notepad because they're unaware of other editors, they'd be using it b

You can set the lints to `forbid` instead of `deny`, which means they can't be `allowed` like that.
