Description:

MySQL today is an entirely different beast than it was two years ago. Recent improvements have increased performance dramatically. I'm not a shill for MySQL, but I often see decisions that are no longer necessary or even wise: sharding prematurely, moving away from MySQL, not buying powerful hardware -- all out of the once-true belief that MySQL could not run with the big dogs. Given the new reality of multicore hardware, solid-state storage, and vast amounts of RAM, what should you be doing today with MySQL to build large-scale apps that perform well? We'll talk about hardware, tuning, what's new in MySQL 5.1 and beyond, and what's specific to Rails apps. And yes, there ARE still parts of MySQL that don't scale well, and we'll discuss how to
sidestep them.

Speaker Bio:

Baron Schwartz is an expert on MySQL and LAMP performance and scalability. He's the Chief Performance Architect at Percona, where he helps customers architect and build some of the largest LAMP applications around. He is the lead author of High Performance MySQL. He has created several popular open-source software projects, including Maatkit. He posts regularly on the MySQL Performance Blog and the Xaprb blog.

June 29: Curing DIV-itis with Semantic HTML, CSS and Presenters by John Athayde

Description:

In the world of web standards, semantic markup is one of those nebulous things that is often blogged about and oft forgotten in the throes of birthing a web application. Semantic markup is using HTML elements for what they are intended (e.g. a ul for a list instead of a div class=”list”). Not only does this make rendered documents easier to read from a hierarchy perspective, but it helps with search engines and reducing code.

In the last year since I’ve joined the staff at InfoEther, we’ve refactored a few sites that have come through, in many cases reducing some Rails partials from 80 lines of code down to 20. That partial was a list with a loop in it for a top-ten list. So, once processed, it rendered out to about 600 lines of code. After cleanup it came out to rendering out less than 100.

We’ve also utilized the Presenter pattern to take elements that occur regularly and remove them to presenters. CSS elements and stylesheets generated from Ruby, Navigation items that are added with one line of code and a few images, easy setup wizards, and more.

All these things can create better sites that run faster and are easier to work with.

Speaker Bio:

John is a interface and experience designer as well as programmer, filmmaker, musician, and occasional troublemaker. Prior to his current role at Northern Virginia’s Ruby on Rails consultancy, InfoEther, he ran the DC based UI/UX shop “Hyphenated People” with Amy Hoy. He also ran a 15 person creative team at a large e-commerce shop for two years. He released a short animated film, “The Sandbox”, with his company Meticulous in 2005. When he’s not emotionally attached to a website, he can be found performing in his band, Juniper Lane, or working on 3d animation and electronic music. He holds a Masters degree in Architecture (the building variety, not the information kind) from Catholic University of America. He takes entirely too many pictures of his cat.

First Talk: An Introduction to ActiveDocument

This talk takes an in-depth look at the new open source Ruby connector to MarkLogic, ActiveDocument. ActiveDocument is an ActiveDocument style object to XML mapping framework for XML databases (currently implemented only for MarkLogic). It allows developers to leverage the power of an XML database to find, create, update and delete XML documents within their XML database without having to write any XQuery code.

During this presentation we will talk briefly about the philosophy behind ActiveDocument and then we will start looking at the important classes and concepts that developers will need to understand in order to create applications with ActiveDocument. From there we will create a Rails application from scratch using ActiveDocument as our connection to our underlying MarkLogic XML server.

About the Speaker: Clark D. Richey, Jr. has spent over ten years architecting and implementing large scale software solutions for the federal government. Currently, Clark is the Principal Technologist, Federal and Community Champion with Mark Logic. Clark is also an adjunct professor with Loyola University where he teaches in their Master's of Computer Science program, where he is currently teaching Ruby on Rails. Clark has a Master's in Computer Science from American University and a Bachelor's in Computer Science from U.M.U.C.

Second Talk: All Your UIs Are Belong to SproutCore!

Gray Herter will introduce SproutCore, an application framework that aims to simplify the building of complex web-based UIs, and demonstrate how to use it in conjunction with Rails to create some fantastic apps.

SproutCore embraces several novel approaches to building web-based UIs. It uses only JavaScript, HTML, and CSS. This results in impressive user experiences without the need for browser plug-ins. To communicate with a server, SproutCore uses only RESTful Ajax calls. While SpourtCore maintains server technology independence, Rails makes a great partner to SproutCore UIs, providing the required access to backend web services.

About the Speaker: Gray Herter is a Senior Software Engineer at Near Infinity Corporation, the founder of DC's annual RubyNation software conference, and has taught and developed using Ruby and Rails since 2007.

Description: Ruby-Processing is an awesome library which wraps Processing with a JRuby interpreter and a simple Ruby syntax. Using ruby-processing your Rails app can programmatically create complex images using static images, 2D shapes, 3D with OpenGL, animation and video.

We can leverage the power of Processing and existing Java libraries from the comfort of Ruby.

In this session we’ll take a quick look at ruby-processing to understand how it works, then add dynamic image creation to a sample Rails app. We’ll discuss the potential of leveraging Processing from Rails and layout directions for further research.

Nov 4: ActiveScaffold and Stop Talking, Start Teaching: 5 Rules for Successful Communication

Gray Herter — Tue, 27 Oct 2009 14:56:00 -0400

Two Topics: ActiveScaffold by David Medinets and Stop Talking, Start Teaching: 5 Rules for Successful Communication by Jeff Casimir

When at Where: Nov 4th from 6:30 PM - 9 PM at FGM, 12021 Sunset Hills Rd, Suite 400, Reston, VA 20175

Pizza and sodas at 6:30. Presentations start at 7 PM

First Presentation: ActiveScaffold by David Medinets

ActiveScaffold is a tool that produces on-the-fly scaffolding that looks much better than the default Rails scaffolding. It uses Ajax to create, update, and delete without page reloads. Also, the scaffold is nearly totally customizable in well-documented ways. In this presentation, David will show how to use ActiveScaffold to produce a custom user interface while still letting the tool do the hard work of generating forms.

BIO: David Medinets has been programming since 1980, starting with a TRS-80 Model 1. He still fondly remembers the days when he could cross-wire the keyboard to create funny-looking characters on the display. Since those days, he has written three books teaching the Perl, PHP, and BASH languages. David is a SCRUM Master and expert application developer specializing in Ruby and Java. He is knowledgeable about the business domains of Insurance, Supply Chain, and Airline Inventory.

Second Presentation: Stop Talking, Start Teaching: 5 Rules for Successful Communication by Jeff Casimir

Some of the most important work we do as programmers involves pitching ideas. Whether it’s inside the team, searching for funders, or running demos for potential clients, we all need to present ideas and cultivate an audience.

The past decade has seen the rise of the presentation as an important communication medium, but few people do it well. There are many resources on how to make good-looking slides, but we need to focus on the method, structure, and content.

We don’t need to be “speakers” – we need to be teachers. In this session we’ll explore the five most essential rules to successful teaching and how they apply to you.

Attendees will, by the end of the session, have a framework for designing and critiquing their work and that of others. This new understanding will make them better teammates and more successful salespeople.

BIO: After majoring in Computer Systems Engineering Jeff joined Teach for America and began a career in education. He taught high school Computer Science for four years before moving into school administration. As a Vice Principal he was responsible for evaluating and hiring new teachers, observing and coaching existing teachers, and defining much of the school’s academic process. As part of that process, he built a “School Information System” (SIS) in Ruby that ran every aspect of the school.

Most of all, Jeff hates boring presentations. He wants everyone to Stop Talking, and Start Teaching.
