Isolate integration with Pubnub (from the Slottd.com codebase)
View message_pusher.rb
# Isolating integration with Pubnub allowed me to swap origin in a central location.
# This seems like a trivial wrapping, almost not worth it at all.
# However, doing this allowed me to quickly fix a production issue associated with out-of-date gem's hard-coding of
# origin for request URL.
# Always worth abiding by the Eliminate Duplication (of knowledge) rule of simple design. In this case, knowledge of how
# to integrate with Pubnub.

How Does The Internet Work (abstract)

How Does The Internet Work
The internet (and the world-wide web) is a wonderful tool for both personal and business use. The details of how it works, though, are often considered a mystery known only to a select few. For example, what's the difference between the "internet" and the "world-wide web"?
The truth is, nobody really knows how it works (just like "how do airplanes actually fly"). Since the early days, when it was given to us by benevolent space aliens, though, research has been able to discern some basic "facts" about its internal operations. In this lunch-and-learn, we'll spend some time going over what we have been able learn.
We'll start with a bit of history of the internet and the related world-wide web. Next, we'll go over some of the inner-workings, striving to answer such questions as:
- What is the difference between the internet and the world-wide web?
- What are web servers and web browsers?
- What is a URL and by what magic does that correspond to a picture of a kitten in our web brow

Lambda Madness Talk Abstract
View abstract.txt
Title:
To create the world, you must first define True
(fun with lambdas)
Abstract:
Perhaps you've seen lambdas in Ruby. Ever wondered what would happen if you went crazy with them? What if they were all you had? What if you only allowed them to take a single parameter?
In this fun talk, we'll start with nothing but the lowly single-parameter lambda and slowly build the world. Of course, to do that, we'll need a testing library, so we'll build that (and explore what True means if we only have lambdas). Then, we'll move onto lists and build the basics of the Enumerable functions (map, select, etc). Can we do this with just the lowly lambda? (spoiler: Yes)
This talk will cover things that are very clearly in the "Do try this at home" zone. So, come along with me and take a deep dive into what can be done when you start with nothing.
(this is based on some fun playing that @joshcheek and I did earlier this year)

# abstract for my talk at Craft Conf 2015 (http://craft-conf.com/2015)
You've probably heard about the lambda calculus, building up our computing structures from just the treasured lambda. But how much have you played with it?
In this talk, armed only with Vim and the CLI, we'll explore some interesting topics in building up our world with just the lambda and the thought process while doing it. While you probably don't want to program day-to-day at this level, it definitely can help with how you think about your regular programming.
This talk consists almost entirely of live coding. FUN TIMES!

View Super Awesome Fun Coding Workshop, Great Job
Idea based on this tweet exchange:
coreyhaines: Architecture where ever class is its own gem, communicating via drb. #thoughtleadering #thoughtlendering
coreyhaines: better yet, every method is its won gem, classes are built up by requiring gems that monkey-patch. #truth
josh_cheek: @coreyhaines As each method is a gem, it needs its a namespace, so it's defined in a module… Compose classes by including method's modules.
coreyhaines: @josh_cheek I do like the idea of composing via module inclusions, as well. Interesting.
coreyhaines: Seriously, though, the idea of defining classes via including single-method modules appeals to me.
So, here's my thought for the workshop. It is based a bit on some of the value that I saw doing coderetreats.

You can’t perform that action at this time.
