This closely resembles implicit conversion from C++ and in many serious codebases it is considered poor practice because it leads to a lot of hidden control flow. I think Rust stri…

Yes, for most real-world examples JavaScript is significantly slower; JIT isn’t free and can be very sensitive to small code changes, you also have to consider the garbage collecto…

Similar to ruff, uv mostly gathers ideas from other tools (with strong opinions and a handful of thoughtful additions and adjustments) and implements them in Rust for speed improve…

This is an oversimplification. When distributed, the nondeterministic order of additions during reductions can produce nondeterministic results due to floating point error. It’s ni…

Lifetime annotations can be burdensome when trying to avoid extraneous copies and they feel contagious (when you add a lifetime annotation to a frequently used type, it bubbles out…

> Don't waste time on discussions within a level. I disagree with this. YAML has too many footguns (boolean conversions being the first among them) not to mention it is a superset …

Thanks for the quick response, and for the nice write up. I thoroughly enjoy the python-like pseudocode, it was the main reason I was able to pick that out reasonably quickly!

In the pseudocode snippet that introduces a WAL, the semaphores are signaled before the fsync occurs. This seems like a mistake but maybe there’s a good reason to do this that I am…

I did some of the work in the post (though mostly post-setup). Speaking in generalities: the initial failure rates of these units are much higher than those of traditional non-GPU …

You may want to add some moderation features or otherwise increase friction for adding job postings for www.firmwarejobs.com because the very first listing that I see when I load t…

I think it's more subtle than that. Rust has a notion of non-lexical lifetimes ( https://rust-lang.github.io/rfcs/2094-nll.html ) and the compiler often completely avoids the use o…

Usually from GC. Anthony Sottile has a nice explanatory video: https://youtu.be/sdmcCQ7Em04?si=9PObAJixALFiZ9vd

Client means browser in this context.

Unfortunately the generational GC modifies bits all over the heap, so you have to use some tricks to really leverage copy on write (as the commenter alludes to).

I don't think I fully understand the analogy. Typescript has almost identical semantics to Javascript but adds typing syntax to improve developer experience and make it easier to m…

There is an option to circumvent the prerequisites as a non-major: You may also get permission from an advisor if you performed very high on the CS Assessment on Canvas. I took the…

"Principles of Imperative Programming" is a misnomer. The course is really about developing techniques for reasoning about low-level software. You build up abstractions in C by lev…

Especially if modular implicits land, you get the best of both functions and typeclasses. Pretty weird way to start the post.

Doesn't the normal approach in C++ run into similar issues? The workarounds in C++ are more ergonomic than in Rust, but can still require a lot of refactoring. One of the performan…

Rust is an interesting mix. OCaml gets pretty close and type inference offers better ergonomics. The fearless concurrency story is still much better in Rust than OCaml.

I'm not sure that it's that cut and dry. Rust provides good tools for building high level abstractions and the developer tooling is comparable to something like typescript. Dependi…

Fatigue is a common side effect of Zyrtec (and other antihistamines). From purely anecdotal evidence, I think most people have to experiment with allergy medication to find one tha…

I'm a big fan of Julia Evans' zines. They're short and to-the-point and are often excellent jumping off points. This one seems highly relevant: https://wizardzines.com/zines/contai…
