Things I believe

This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.

Agree? Disagree? Feel free to let me know at @JanStette.

Fundamentals

Keep it simple, stupid. You ain't gonna need it.

Get started with [Mocha] testing

Make a package.json file if you don't have one yet:

npm init
# just keep pressing enter.
# this will create the file `package.json`

Ruby on Rails coding standard

Code style

Use UTF-8. It’s 21 century, 8bit encodings dead now.
Use 2 space indent, not tabs
Use Unix-style line endings
Keep lines not longer than 80 chars

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

I have moved the regular expression example repository to the regular GitHub site to encourage contributions.

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"
