#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?

I am in the process of introducing single page applications to where I work. For development, using node based build tools is much easier for the single page applications. However, the build process for our organization is based upon maven. Our solution started with the maven plugin frontend-maven-plugin. It worked great at first, but then we ran into a situation that I couldn't make work with it.

As stated before, at our organization, we have the older ecosystem which is maven and the newer ecosystem which is node. Our goal was to keep the hacking to a minimum. We did this by putting all of the hacks into a single super node based build file. This is what maven calls and the reason frontend-maven-plugin wasn't sufficient. The super node based build script calls all of the other build scripts by spawning npm run. Try as I might, I could not figure out how to make the spawn work. front-end-maven-plugin downloads npm

How to download streaming video

Streaming just means a download that they don't want you to keep. But Chrome's developer tools make it easy to access what's really going on under the hood.

Open Developer Tools

From the page where you want to download some things, go into your chrome menu to open the developer tools. You can either:

1.  (On a mac): Command-option-J
2. (On a PC): Control-alt-J
