GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

1. Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
2. Create or import a key -- see below for https://keybase.io
3. Run gpg --list-secret-keys and look for sec, use the key ID for the next step
4. Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

// A: is this pure function?
function sum(a, b) { return a + b }
// B: is this a pure function?
const k = 2
function addK(a) { return a + k }
// C: is this a pure function?
function sub(a, b) { return sum(a, -b) }
// D: is this a pure function?
function sub(a, b, summer) { return summer(a, b) }
// E: is this a pure function?

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !

Tuple

myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

The future is here: Classless object-oriented programming in JavaScript.

Douglas Crockford, author of JavaScript: The Good parts, recently gave a talk called The Better Parts, where he demonstrates how he creates objects in JavaScript nowadays. He doesn't call his approach anything, but I will refer to it as Crockford Classless.

Crockford Classless is completely free of class, new, this, prototype and even Crockfords own invention Object.create.

I think it's really, really sleek, and this is what it looks like:
