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?

Using Swift libraries in Python

So... this is obviously totally, 100%, like for. real. not. supported. by. Apple. …yet?

But still... I thought it was pretty badass. And, seeing how there's already a Swift buildpack for Heroku you could move some slow code into Swift can call it as a library function. But, you know, not in production or anything. That would be silly, right?

Now, having said that, the actual Python/Swift interop may have bugs. I'll leave that as an exercise to the reader.

How to get Python code calling Swift functions:

yum install -y wget
wget http://rpms.adiscon.com/v8-stable/rsyslog.repo
mv rsyslog.repo /etc/yum.repos.d/rsyslog.repo
yum info rsyslog --skip-broken
yum install -y rsyslog
rsyslogd -version

#!/bin/bash

# An set of disks to ignore from partitioning and formatting
BLACKLIST="/dev/sda|/dev/sdb"
# Base directory to hold the data* files
DATA_BASE="/media"

usage() {
    echo "Usage: $(basename $0) <new disk>"
}

The problem

If a function calls itself recursively then the JavaScript engine has to create a new 'stack' (i.e. allocate a chunk of memory) to keep track of the function's arguments.

Let's look at an example of this happening:

function sum(x, y) {
    if (y > 0) {
      return sum(x + 1, y - 1);
