System Design Cheatsheet

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

Basic Steps

1. 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?

Vim, Vundle and ConEmu on Windows

Let's start by getting it out on the table: Sublime Text is great, and version 3 should no longer be considered "abandonware" as of build 3065. Sublime Text served me very, very well over the years. That said, trying out new things is a major part of leveling-up, and in that vein Vim deserves a go. (And have you seen some of those thoughtbot guys flying around in Vim? It's awesome!)

Getting Vim up-and-running on your Windows machine doesn't have to be an all-day project. In this post, we'll walk through:

• Installing gVim, which gives us both the "classic" command line version as well as the graphical version
• Installing Vundle, the best way to handle Vim-enhancing packages
• Installing ConEmu, a supercharged command line emulator for Windows

  flac -s -d --force-aiff-format -o "$aiff" "$flac"
  afconvert -f m4af -d alac "$aiff" "$alac"
