Setting up a Github Pages Project Page with Circle CI

Greetings! This will guide you through a basic setup of a Github pages project with Circle CI. All examples here are meant to be as clear as possible - there may be different and quicker ways to do some of these things, but this tutorial is biased on the side of clarity rather than brevity.

Setting up Github Pages with a project

You need a Github repo with an index.html file in it (for an example, check out My personal website. This tutorial assumes you have merge permissions with the repo.

Now, check out this repository to your workstation and create a new gh-pages branch.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

You got your hands on some data that was leaked from a social network and you want to help the poor people.

Luckily you know a government service to automatically block a list of credit cards.

The service is a little old school though and you have to upload a CSV file in the exact format. The upload fails if the CSV file contains invalid data.

The CSV files should have two columns, Name and Credit Card. Also, it must be named after the following pattern:

YYYYMMDD.csv.

A tweet-sized debugger for visualizing your CSS layouts. Outlines every DOM element on your page a random (valid) CSS hex color.

One-line version to paste in your DevTools

Use $$ if your browser aliases it:

#How I built an audio book reader for my nearly blind grandfather

Last year, when visiting my family back home in Holland, I also stopped by my grand-parents. My grand-father, now 93 years old, had always been a very active man. However, during the presceding couple of months, he'd gone almost completely blind and now spent his days sitting in a chair. Trying to think of something for him to do, I suggested he try out audio books. After finally convincing him -- he said audio books were for sad old people -- that listening to a well performed recording is actually a wonderful experience, I realized the problem of this idea.

####The problem with audio devices and the newly blind. After my first impulse to jump up and go buy him an
