FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

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?

Issues with latex math in markdown files, for display on Github Pages (using jekyll)

Our solution: use kramdown parser, with GFM option (Github flavored Markdown). In the .Rmd, use $$ for display math and $ for inline math. then have a script which turns the inline math demarkation in the .md file from $ into $$ when appropriate (avoiding data frame usage), before uploading the .md to Github. This way, RStudio preview looks the same as the Github Pages version.

redcarpet math

• doesn't respect $ or $$ (will parse characters within these, such as _), but has workarounds:
• has a useful option, no_intra_emphasis, so underscores between ascii characters are not converted to <em> tags, so $x_1$ is fine
• need to escape underscores after non-ascii characters, for example $\mathbf{x}\_1$
• need to double escape curly bracket: \\{

Step 1: Server Credentials

This assumes you are now connected to the server via SSH.

• sudo -s Enter root mode for admin access
• groupadd devgroup Create new group to be later granted access to /var/www/html

Creating a new Root User

• useradd -G root,devgroup masterdev Create new root user. Also add to the devgroup
• passwd masterdev Change password for the new root user
• At this point, you'll need to input your new root user's new password
