This is often stated but it literally can't be true. It's true for stationary solutions to the relevant equations, but we're very much not living in a stationary world. Here's a simple thought experiment disproving you

XXH3 does not have this property, no more than foldhash does.

That's not what ternary refers to here. In C, '+' is a binary operator because it accepts two inputs. '?:' is a ternary operator because it accepts three inputs. It is usually referred to as the ternary operator b

Why was Rust's hashmap only tested with SipHash? It's known to be pretty bad for performance. I'm biased as the author of course, but try adding a benchmark with the Rust hasher + foldhash as well: https://github.c

I've had good results in the past with sollya: https://www.sollya.org/ . Note: results. The software itself is a bit of a pain to use.

Not a lawyer, not legal advice, but... the legal status quo is that neural network outputs are not copyrightable. They are currently considered not made by humans nor considered a derivative work from the training material / network we

Not the person you replied to, but I use Iosevka Fixed which is default except everything is always fixed-width and there are no ligatures.

People that do believe you need to be innovative are in for a rude awakening when they actually do something innovative successfully only to find out a year later there are now 5 competitors copying you, with decent success.

The title says 300μs typo detection . How? If the query doesn't finish in 300μs, return error :)

I would normally agree, but the author went out of their way to check for error conditions in their binary search. I think a silent infinite loop is antithetical to that.

This binary search is pretty bad in my opinion. Some issues: 1. It doesn't support the empty array, because l and r are both inclusive. 2. It performs way more predicate tests than necessary. 3. An incorrectly implemented Mid trait cau

There is another alternative which may be significantly more efficient as it means the caller always gets back a direct iterator instead of an enum it must branch on: make a dummy empty hashmap with a static lifetime you can refer to. Then

Is it? My compute-bound tight loops on x86-64 are often decode-bound.

It doesn't, but it's typically the simplest (for me). It also means I get exactly the version I want compiled with the best optimizations for that machine.

What I do on every dev machine is build Python from source and install it to ~/.localpython and put it in my path. Then I can pip install away care-free, and quickly run scripts / repls without having to activate an environment.

I'm the author of slotmap. I don't know why slotmap is listed as not having ABA protection, when it absolutely does. EDIT: I've emailed the author.

What are you basing that on?

For what it's worth, I recommended against mentioning `unpredictable` anywhere in the name when we stabilize the intrinsic. IMO the constant-timeness is much more important, e.g. in audio DSP code or for cryptography you really care th

Rather than std::swap_if which is rather niche, I would prefer to see std::select(cond, if_true, if_false), with the guarantee that unlike the ternary operator it eagerly evaluates both arguments and selects between them branchlessly if pos

You don't even need that for JSON. JSON can be expressed using a LR(1) grammar, so you can do it in linear time and space.

Not a lawyer, but the cynic in me assumes that it is legal bait: if someone at the company cashed the $10 gift card one could argue that compensation for damages has been accepted and no further liability applies. At least legally speaking,
