Our shower has two dials: temperature and pressure. The temperature dial has a specific temperature that it will "snap" to. (When increasing temperature, it will stop there unless you hold in a button. It doesn't snap when de

An interesting example is chessable, which is a spaced repetition system for chess. It keeps track of each move in a sequence of moves separately, but every time it asks you to re-learn a specific move, you are asked to play out the whole s

In my experience, you can get it to change its mind by troubleshooting the connectivity issues. E.g. if you use dig to get the ip and then ask curl to use that ip instead of a dns lookup, then it works for me.

Maybe that first value is a bunch of zeroes? Since you mention Rust, here's a neat piece of trivia: `vec![0; N]` compiles down to a `calloc` call. (Well Rust's own version of `calloc`.)

> If you assign a primitive type's value to another variable, the value is copied - not assigned a reference to the first variable (which is what happens for objects). Assigning an object also just copies the value - i.e. the refere

They mean the amount of storage, and they're only counting additional memory allocated by the algorithm, and not the memory containing the input.

They are not the same. "Expected" refers to the running time of a single operation when it uses randomness. "Amortized" talks about what happens when you call the same operation multiple times (it has nothing to do with

I have two monitors of this model and they work great with both my work and personal laptop, both of which run Linux. You can connect the monitors with a display port cable, then use a single USB-C cable to connect both to the laptop in one

In my case I sometimes work from home and sometimes from the office. The laptop is handy since I can bring it with me and use the same computer at both workstations, both of which have external monitors.

Link cut trees. They can be used to query information about paths in a forest, while also allowing you to add and remove edges in the forest. For example, you could use them to store the minimum spanning tree of a graph, while supporting up

It's not possible to have multiple 1.x.y versions of the same crate in your project, so you would need a really old library that depends on Tokio 0.2.x for that to happen. This isn't something that normally comes up in practice.

Why do we need an explicit construct for this as opposed to e.g. having the compiler replace the tail call with a goto back to the beginning of the function?

The difference has to do with ownership, and it has nothing to do with mutability. For both types, you can mutate them given a mutable refence, and you can't given an immutable reference. For an example, an `&mut str` can be modi

The notation means that it must be faster than m^t for any t strictly greater than one. Basically, it means that you can have any number of log factors on the running time, so it could be m*log(m)^1000

You already have to spend the time to go through the list. Just add up the xor as you iterate through the list.

The way those languages implement something that is uncolored is by making everything async. Rust has some other use-cases where that's not acceptable.

It is perfectly reasonable that `from_utf8_unchecked` is unsafe because the sequence of operations `from_utf8_unchecked(array).chars().next()` will call [1] and can trigger memory unsafety with the `unwrap_unchecked` call if the array is no

The Rust Vec type has an unsafe function called `set_len` that changes the length of the vector without checking whether the new length is in bounds, or whether the memory containing any new values is initialized. The body of the function i

They used the real inputs. The example inputs were used to filter out which candidates to submit for the 10 tries.

No, they gave the algorithm 10 tries and tested all of them, and said that it was solved if any one of them worked.
