You're right, these posts assume one knows what the Y combinator is for. Wikipedia has a decent explanation: https://en.wikipedia.org/wiki/Fixed-point_combinator Key point: the Y combinator implements simple

That's a good point, thank you for bringing it up. Finding the right examples is really tricky. sort.Search is binary search and hence a bit tricky to benchmark properly because of how ridiculously fast it is. Only a handful of compari

The change mentioned at the top of the post ( https://go-review.googlesource.com/c/exp/+/378134 ) also has a benchmark to compare sorting structs using sort.Slice vs a new generic approach that uses a compariso

Thank you for the thoughtful comment. I'm actually aware of cargo doc - it's really useful, indeed. It's still note quite "greppability" though; I can open `cargo doc`. I can just open the browser and google "r

No kidding :) This post is now #3 on google for "greppability"

Thanks for the comment! I actually forgot to run clippy on these samples because they're so small; I'll fix up the code in the post to be more idiomatic.

A lot of my reading is audiobooks. I love audiobooks - they enabled my reading levels to go way up in the last few years. Some more details about this here: https://eli.thegreenplace.net/2020/my-reading-habits/

Fair question. I spend some time researching books before I read them; very low signal-to-noise books typically will have reviews saying that. I also mostly avoid whole categories of books which are prone to this; I still get bitten once in

Books Seriously. Books are the ultimate long-form content; their authors typically spend years researching and writing them, and you can sample many reviews before committing to read one.

What confuses me about these reports is that the relevant South African districts report ~25% vaccination rates; so it sounds unlikely that the mildness observed is due to previous immunity. Or is the assumption that most of these people ha

You can pay for gmail too, and get phone/chat/email support via https://one.google.com/about/plans (basic plan is less than $2/month) Doesn't this work for folks?

Thanks, you're making a good point. I like how you phrased the problem here, will ponder about updating the wording of the post slightly to reflect that.

`Rc` implies ownership, albeit shared one. So if a heap location is held by `Rc`, all reference to it should be either `Rc` or `Weak`. You can't have an `Rc` and a `Box` for the same data, IIUC. A `Box` is unaware of `Rc` and will drop

Thanks for the pointer! My goal in the post was to avoid "just use this crate" approaches, because clearly there are dozens of crates that could help with this... even crates that implement BSTs :-) The goal was to look at the und

I had this approach in a draft as well! In fact, I tried this before making all links `*mut Node`. But coding the removal methods turned out to be really hard - I couldn't fight through the borrow checker. So I figured if I already hav

What does "reliably measured" mean? Isn't the record 134F, measured in 1913? I wonder what the backstory here is.

Yes, age and life expectancy is a huge part of it. In the book "Rebel Cell: Cancer, Evolution, and the New Science of Life's Oldest Betrayal", Kat Arney touches upon this exact question and reaches the conclusion that cancer

Thank you for the detailed comment! Just want to address (1) quickly. As you've mentioned at the end of the parenthesized note, the reason I did not use `defer` here is to avoid the lock staying across the rest of the handler. I wanted

Could someone ELI5 why proteins fold in a unique way? Why can't there be multiple "valid" ways for them to fold (ignoring mirror symmetries)?
