 Swift Programming Language Guide
 "A Swift Tour" Solutions
 https://developer.apple.com/library/prerelease/ios/documentation/Swift/Conceptual/Swift_Programming_Language/GuidedTour.html#//apple_ref/doc/uid/TP40014097-CH2-XID_1
 
 These are the solutions to all the "experiments" in the pre-release Swift Programming Guide 
 (released on the same day Apple announced Swift). A couple of things worth noting:
 
 1. Swift syntax, e.g. array declarations, has changed since I releasd these. So this code will 
    probably cause some errors when you paste it into a playground. Should be easy enough to fix

Spurred by recent events (https://news.ycombinator.com/item?id=8244700), this is a quick set of jotted-down thoughts about the state of "Semantic" Versioning, and why we should be fighting the good fight against it.

For a long time in the history of software, version numbers indicated the relative progress and change in a given piece of software. A major release (1.x.x) was major, a minor release (x.1.x) was minor, and a patch release was just a small patch. You could evaluate a given piece of software by name + version, and get a feeling for how far away version 2.0.1 was from version 2.8.0.

But Semantic Versioning (henceforth, SemVer), as specified at http://semver.org/, changes this to prioritize a mechanistic understanding of a codebase over a human one. Any "breaking" change to the software must be accompanied with a new major version number. It's alright for robots, but bad for us.

SemVer tries to compress a huge amount of information — the nature of the change, the percentage of users that wil

ndb.Model - migrating properties like a boss

The problem

Consider following model:

class X(ndb.Model):
    prop1 = ndb.StringProperty()
    prop2 = ndb.StringProperty()

MoOx

// go on you labels pages
// eg https://github.com/cssnext/cssnext/labels
// paste this script in your console
// copy the output and now you can import it using https://github.com/popomore/github-labels !

var labels = [];
[].slice.call(document.querySelectorAll(".label-link"))
.forEach(function(element) {
  labels.push({
    name: element.textContent.trim(),

How to show migration guides in GitHub Markdown

Use the diff code highlighting tag.

  ```diff
  - foo
  + bar

Example:

Isaddo

/*
  Go on your labels page (https://github.com/user/repo/labels)

  Edit the following label array
  or
  Use this snippet to export github labels (https://gist.github.com/MoOx/93c2853fee760f42d97f)
  and replace it

  Paste this script in your console
