// Should I be ES6+ing this file? Does it matter? Seems like it would feel nicer but running Babel over this file feels like ouroboros.

// I'm using Gulp 3.x. I couldn't for the life of me get Gulp 4.x going, I think because my Gulp CLI was at too high (??) of a version and no amount of uninstalling and reinstalling would bring it back down.

// I thought I needed this until I found out about gulp.series. Can I refactor anything here?
var runSequence = require("run-sequence");

// Would this be a speed boost for anything? As in, only looking at files that have changed instead of all files?

A series of posts on css-in-js

0. styles as objects

First, an exercise. Can we represent all of css with plain data? Let's try.

let redText = { color: 'red' };

TL;DR

Install Postgres 9.6, and then:

sudo pg_dropcluster 9.6 main --stop
sudo pg_upgradecluster 9.5 main
sudo pg_dropcluster 9.5 main

Simple automated GIT Deployment using GIT Hooks

Here are the simple steps needed to create a deployment from your local GIT repository to a server based on this in-depth tutorial.

How it works

You are developing in a working-copy on your local machine, lets say on the master branch. Most of the time, people would push code to a remote server like github.com or gitlab.com and pull or export it to a production server. Or you use a service like deepl.io to act upon a Web-Hook that's triggered that service.

TL;DR

9.4 -> 9.5:

sudo pg_dropcluster 9.5 main --stop
sudo service postgresql stop
sudo pg_upgradecluster -m upgrade -k 9.4 main
sudo su postgres -c "/usr/lib/postgresql/9.5/bin/vacuumdb --all --analyze-in-stages"
sudo pg_dropcluster 9.4 main

/*
A zero-indexed array A consisting of N integers is given. An equilibrium index of this array is any integer P such that 0 ≤ P < N and the sum of elements of lower indices is equal to the sum of elements of higher indices, i.e. 

A[0] + A[1] + ... + A[P−1] = A[P+1] + ... + A[N−2] + A[N−1].

Sum of zero elements is assumed to be equal to 0. This can happen if P = 0 or if P = N−1.
