@joshgad Hi and thanks from Maryland! Ever read The Book with No Pictures?

[John Gallagher @nerdyjkg]

@steveklabnik @Carols10cents CppCon bookstore had several piles of the Rust book on Sunday - now sold out. 👍

@tqbf I'm sure I've seen that first picture before... where was it... oh yeah

@kulkarniankita9 @bignerdranch @matthewDmathias Sorry, our days are packed! There have been some good WWDC videos covering it, though.

[John Gallagher @nerdyjkg]

@bignerdranch @kulkarniankita9 @matthewDmathias We use Travis, Circle, and Xcode server on various projects. Pros and cons to each

[John Gallagher @nerdyjkg]

@cocoaphony @borkware You can keep embedded Error if you make the protocol Swift.Error explicitly.

[John Gallagher @nerdyjkg]

@Argorak rustup didn't exist when I wrote that. 😀 Would definitely use it now instead of building the toolchain.

The word “just” is one of the worst words that a developer can hear on a project.

“Can you just … ?”
“You just need to … .”

@imsachinraut @matthewDmathias Yes, with no ! necessary - `documentDirectoryURLs[0]` gives the same result as `documentDirectoryURLs.first!`

I <3 this regex helper, because it draws the pretty pictures I see in my head when writing a regex: https://t.co/r6rZ7l2hHy

[John Gallagher @nerdyjkg]

@msaleem @matthewDmathias For articles about this concept in other languages, try searching "error vs exception" or "assert vs exception"

[John Gallagher @nerdyjkg]

@msaleem @matthewDmathias precondition is for catching programmer errors (bugs). emptyGas should never be called with a value outside (0, 1]

[John Gallagher @nerdyjkg]

@msaleem @matthewDmathias Right, different inits have to differ in their arguments somehow (names/number of args/types of args).
