How to update the Go version

System: Debian/Ubuntu/Fedora. Might work for others as well.

1. Uninstall the exisiting version

As mentioned here, to update a go version you will first need to uninstall the original version.

To uninstall, delete the /usr/local/go directory by:

# Basic commands

    :Git [args]              # does what you'd expect

all of your `~/.gitconfig` aliases are available.

    :Git! [args]             # same as before, dumping output to a tmp file

Moving inside a repo.

Array Iteration

While attempting to explain JavaScript's reduce method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.

Intro

JavaScript Arrays have lots of built in methods on their prototype. Some of them mutate - ie, they change the underlying array in-place. Luckily, most of them do not - they instead return an entirely distinct array. Since arrays are conceptually a contiguous list of items, it helps code clarity and maintainability a lot to be able to operate on them in a "functional" way. (I'll also insist on referring to an array as a "list" - although in some languages, List is a native data type, in JS and this post, I'm referring to the concept. Everywhere I use the word "list" you can assume I'm talking about a JS Array) This means, to perform a single operation on the list as a whole ("atomically"), and to return a new list - thus making it mu

Recently when refactoring a Vue 1.0 application, I utilized ES6 arrow functions to clean up the code and make things a bit more consistent before updating to Vue 2.0. Along the way I made a few mistakes and wanted to share the lessons I learned as well as offer a few conventions that I will be using in my Vue applications moving forward.

The best way to explain this is with an example so lets start there. I'm going to throw a rather large block of code at you here, but stick with me and we will move through it a piece at a time.

// require vue-resource...
