# Key zram params:
# mem_limit: maximum amount of ram it will ever be allowed to eat.
# disksize: filesytem size, may be larger than mem_limit, because of compression.
# comp_algorithm: lz4 gives about 2x compression for most builds.
# backing_dev: device to dump uncompressable pages to, must be set before size. Must use a script to drop pages, not automatic.
#
# Key mkfs options:
# '-e remount-ro' to go read-only on errors, it stops the build properly
# '-m 0' to skip root-only reserved 5% of space
# '-O ^has_journal' to skip journal. it's disposable FS and we will never run fsck on it

Haskell Cheat Sheets

by Victor Payno

The goal of these Gists is for me to have a place to look up all things Haskell. Hopefully they will be useful to other people as well.

Python Cheat Sheets

by Victor Payno

The goal of these Gists is for me to have a place to look up all things Python so I can stop trying to use Perl or Ruby syntax when writing Python code. Hopefully they will be useful to other people as well.

Objects

To create a new object, use the new keyword followed by a call to a constructor function. Javascript provides the Object() constructor out-of-the-box:

var toilet = new Object();

Properties

Once you have an object, you can set and get properties on it, like this:

Screencasting Framework

The following document is a written account of the Code School screencasting framework. It should be used as a reference of the accompanying screencast on the topic.

Why you should care about screencasting?

You're probably aren't going to take the time to read this document if you're not interested, but there are a lot of nice side effects caused by learning how to create quality screencasts.

1. Communicating more effectively - At Envy Labs we produce screencasts for our clients all the time. Whether it's demoing a new feature or for a presentation for an invester, they're often much more effective and pleasent than a phone call or screen sharing.
