Can you use the oxygen trick to practically extend snorkelling dives?

I used to do a little scuba, but overall didn't like the reliance on often poorly maintained kit. But I do love snorkelling - the lightness and simplicity of it.

Can I breathe pure oxygen for half an hour on the boat and be able to repeatedly snorkel longer?

Even though you can do it with pure oxygen, it won't be fun. This is because our breathing reflex activated from the rising carbon dioxide levels - meaning that for a significant portion of the attempt the person was fighting their urge to breathe.

I'm not even sure why we are still stuck in this debate. Isn't there quite a big consensus that the best way to handle errors is to have everything return an `Either<T, Error>` and having first-class support for monadic types?

Any design that doesn't actually force you to handle the error case cannot be called good in my opinion.

> Java is a great language because it's boring [...] Types are assertions we make about the world

This is less of a mind-was-changed case and more just controversial, but... Checked Exceptions were a fundamentally good idea. They just needed some syntactic sugar to help redirect certain developers into less self-destructive ways of procrastinating on proper error handling.

In brief for non-Java folks: Checked Exceptions are a subset of all Exceptions. To throw them, they must be part of the function's type signature. To call that function, the caller code must make some kind of decision about what to do when that Checked Exception arrives. [0] It's basically another return type for the method, married with the conventions and flow-control features of Exceptions.

[0] Ex: Let it bubble up unimpeded, adding it to your own function signature; catch it and wrap it in your own exception with a type more appropriate to the layer of abstraction; catch it and log it; catch it and ignore it... Alas, many caught it and wrapped it in a generic RuntimeException.

Nah, I think having a monadic Maybe/Option type and first-class support for it is the correct solution. Exceptions are fundamentally flawed.

Should be noted that any ensemble that consists only of continuous-pitch instruments (eg. strings, trombone, human voice, fretless guitar) is free from the shackles of 12TET and its harmonies naturally tune to as close to "pure" intervals as the performers’ skills allow.

The guitar doesn't event need to be fretless; there is a lot of leeway (even towards flat) even with frets if you know the technique!
kaapipo commented on A wonderful coincidence or an expected connection: why π² ≈ g   roitman.io/blog/91... · Posted by u/signa11

If the length of a meter were defined as the length of a seconds pendulum [1], then g would equal exactly π². From the pendulum equation:

`T = 2π√(L/g)`

substitute T = 2 s and L = 1 m:

`2 s = 2π√(1 m / g)`

solve for g:

`g = π² m/s²`.

This holds up in any strength of gravity, but the length of a meter would be different depending on it.

[1]. This actually was proposed by Talleyrand in 1790. Imagine the world if this were true!
