Bundler - Bundler maintains a consistent environment for ruby applications. It tracks an application's code and the rubygems it needs to run, so that an application will always have the exact gems (and versions) that it needs to run.
rabl - General ruby templating with json, bson, xml, plist and msgpack support
Thin - Very fast and lightweight Ruby web server
Unicorn - Unicorn is an HTTP server for Rack applications designed to only serve fast clients on low-latency, high-bandwidth connections and take advantage of features in Unix/Unix-like kernels.
SimpleCov - SimpleCov is a code coverage analysis tool for Ruby 1.9.
Zeus - Zeus preloads your Rails app so that your normal development tasks such as console, server, generate, and specs/tests take less than one second.

    PSQL

Magic words:
psql -U postgres
Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

    JavaScript function hoisting by example

Below are many examples of function hoisting behavior in JavaScript. Ones marked as works successfuly print 'hi!' without errors.
To play around with these examples (recommended) clone them with git and execute them with e.g. node a.js
Notes on hoisting

    Kubectl output options

Let's look at some basic kubectl output options.
Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).
We can start with:
