# Makes an enum class with instances (class attributes) having uppercase 
# names while the string representations can be in any case. For example, 
# Color = enum_class('Color', 'red', 'amber', 'green') returns class Color
# with members Color.RED, Color.AMBER, and Color.GREEN. The __str__ instance 
# methods produce 'red', 'green', and 'blue', respectively. To get the 
# instance from the string, use, for example, Color.from_string('blue'), 
# which will return Color.BLUE.

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?

# dontforget
#
# A stupid script for short term reminders in bash
#
# Arguments just need to contain a number and a bunch of words.
#
# The number can be anywhere in the arguments, but there shouldn't
# be any other numeric digits.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

        let layout = NSLayoutManager()
        layout.addTextContainer(container)
        storage.addLayoutManager(layout)
        storage.addAttributes(attrs, range: NSMakeRange(0, storage.length))
        container.lineFragmentPadding = 0.0
        let _ = layout.glyphRangeForTextContainer(container)
