May Meeting: David Bock, Arild Shiraz and Ruby Metaprogramming

2012-05-02T02:15:00Z

Meeting Details

Date: Tuesday, May 8, 2012

Additional Information: 804 RVA Meetup

Abstract

Ruby Metaprogramming Point - Counterpoint

Arild Shirazi’s last project required state-based permissions. Cancan and similar gems did not provide the power or flexibility I was seeking in a DSL. Writing permissions checks by hand throughout the controllers and views is not a maintainable solution. How hard can it be to write your own domain specific language?

Not that bad once you understand closures, classeval, instanceeval and metaprograming hooks like #included(base). I will go over some of these basics as we build our own authentication DSL. The goal is to demystify the Ruby magic and make it accessible for your needs.

To solidify your newfound understanding of what you just learned, Dave Bock will deliver a counterpoint presentation: There is no such thing as Metaprogramming.

Secrets Of The Asset Pipeline

From Ken’s Meetup Meeting description: Following up from my recent deep code dive into the less-rails and less-rails-bootstrap gems come some of the best hidden features of the rails asset pipeline. My talk will include a behind the scenes look of what makes the asset pipeline possible, best practices, advanced usage followed by a review of some of the top level CSS frameworks being used.

March Meeting: M. Scott Ford and Train to Test

Abstract

Train to Test

Many pundits would have you believe that the switch from a developer to a developer tester is just a bit that you can flip in your head. I claim that this is false.

While testing is something we all know that we should be doing more of, many of us are struggling to figure out how. Chances are you’re somewhere in between a developer that never tests and one that tests every time s/he should. And I bet that you’re unhappy with where you are at, and you’d like to figure out how to get closer to where you want to be.

Using the metaphor of going to the gym, I’ll go over some exercises that you can perform. Some of these exercises you’ll be able to perform on your current projects, while others you may want to try out on a toy or side project first. These should help you feel better about how often you test, and it might be easier than losing a few pounds.

Bio

M. Scott Ford (@mscottford), a Senior Developer at Rails Dog, LLC is passionate about software. It’s what he was born to do and he feels privileged to live his dream every day. Writing in Ruby is so much fun, it’s been his favorite language for the past five years. He likes its flexible type system, how it facilitates meta-programming, and how focused the tools are on best practices. He’s worked on Ruby projects using Spree, Locomotive, Mongoid, Devise, Radiant, Nokogiri, and obviously Rails, Sinatra, cucumber and rspec. He was a testing fanatic before Ruby, so the testing tools are what brought him here. He’s loving every minute being a Ruby developer and is looking forward to more work in this space.

The ﬁrst Start Norfolk was held in November, 2011 at Innovation Research Park on the ODU campus. The weekend long event kicked off with 37 business ideas pitched to the team of judges, eight of the 37 ideas were selected for further development. Teams were selected and work began on building the original concept into an viable business. TutoriALL, a tutorial creating app for mobile phones, was selected as the ﬁrst Start Norfolk winner.

November Meeting: Clean Ruby - Simplify your programs with intention revealing, obvious code.

2011-11-02T16:13:00Z

Please note that this is a non-standard meeting location.

Meeting Details

Date: Tuesday, November 8, 2011
Time: 6:00 PM
Location: Dominion Digital, 4101 Cox Rd, Glen Allen (Google Maps link)

Abstract

Despite our use of frameworks like Ruby on Rails being famous for conventional code, we still find ourselves with complicated and difficult to understand applications. Worse yet, our automated tests often end up just as complicated and slow. We have helpful design patterns to follow, so why does our code become more difficult to understand as our application grows? The cure for our pain is following DCI conventions to separate what our program *is* from what it does and to let our user’s mental model of our programs shine through.

October Meeting: There Are No Tests!

2011-10-04T21:35:00Z

Please note that this is a non-standard meeting location.

Meeting Details

Date: Tuesday, October 11, 2011
Time: 6:00 PM
Location: Dominion Digital, 4101 Cox Rd, Glen Allen (Google Maps link)

Abstract

The Ruby community is obsessed with testing, supposedly. In my experience about four out of five applications have either zero or completely ineffective test coverage.

Have the courage to change it. Whether your own projects or recovering someone else’s mess, let’s talk strategy:

Starting with metrics
Refactoring for understanding
Comment-driven development
The unit testing foundation
Bug reports are your best integration tests
Focusing on value
Rescue projects are popping up everywhere, and a strategic testing approach can save the day.

Recap of Tuesday's Meeting on Chef

2011-05-15T12:45:00Z

Many thanks to Kirk (not Dirk) Richey for coming down and giving an excellent talk on Chef. Kirk did a great job of breaking down the nuances and warning against the pitfalls of learning Chef. I know many of us are exploring the cloud and will make good use of Kirk's introduction to the domain of distributed systems configuration.

Just to mention some upcoming events:

RailsConf starts tomorrow.
Next month we'll be doing a joint meeting with Richmond Java Users Group featuring Hiro Asari on JRuby.
In July Jeff Casmir will be doing a talk on "blowing up your Rails views".
Our August meeting will be a social, details coming soon.
Finally, we're going to do a panel on Ruby entrepreneurs in the central Virginia region. If you run your own consultancy, freelance, or run a startup, or used to and went back to wage slavery, you might belong on our panel. Contact us if you're interested!

May Meeting: Cloud Hopping with Fog and Chef

2011-05-04T13:00:00Z

May features two very special speakers from Charlotte, NC: Jim Van Fleet, the original founder of CVREG, and Kirk Richey. They'll be discussing automated system configuration management strategies with an eye towards cloud architectures.

Meeting Details

Date: Tuesday, May 10, 2011
Time: 5:30 PM, talk starts at 6:00 PM
Location: Weinstein Properties, 3961 D Stillman Parkway, Glen Allen, VA 23060

Abstract

The Cloud has all the mindshare when it comes to hosting and capacity planning, but what does it really get you? Kirk Richey will demonstrate how the combination of an abstracted provisioning API and configuration management with Chef can get your environments ready for action in no time flat, without having to depend on any vendors. That leaves you in control to plan the capacity, performance, and price of your operations.
