Summary
Scott Shaw, Director of Services at ThoughtWorks, and Martin Fowler, Chief Scientist at ThoughtWorks, talk about the need for a new relationship between the business department and the IT department.

Designing a web page that is optimized for the iPhone isn't rocket science. It's the same HTML, CSS and JavaScript that you already know. The difference is that browsers and screens do not vary, you know exactly what you are dealing with. You can use that to your advantage and think about that experience when you create your UI. I start out with how to get your page formatted correctly, how to have differnet stylesheets for portrait and horizontal mode, how to create a "Back to Top" button, and then show some iPhone pages I've made.

In this session, we will talk about various options for hosting your Geo data, including Google App Engine. We will outline different design patterns, highlighting the advantages and disadvantages of each, and show code samples. Specifically, we will look at storing Geo data as static files, in databases, and extracting Geo data from Google properties, such as Calendar and Spreadsheets.

This will be a higher level talk, focusing on overall design. However, some knowledge of scripting languages and databases would be helpful, as well as a basic understanding of KML and the Google Maps API.

I’ve noticed that when people try to improve the state of the art of software design, they try to think bigger: big patterns, big principles, discussions about classes and modules and components, layers and tiers. Last year I heard a talk called “Strategic Design”.

But I’ve personally had a lot better luck thinking small.

In this talk, we’ll explore just a few small-scale, tactical design principles, and how they can help you and your team build better systems.

Having worked with RoleModel Software in Raleigh, NC, I’ve since moved to Tanzania, East Africa, where my wife runs a home for street children. I’m continuing to develop software for local organizations and have started pairing with a local guy who just graduated from university.

There are a number of non-profits doing worthwhile work here, but most of them are too understaffed and underskilled to address their computer needs. At the same time, people looking to write software have very little opportunity to learn from skilled developers.

It’s a nice intersection of low-hanging fruit opportunities: we can make big differences both to the organizations we help and to the guys we program with just by putting together a small Rails app with them.

It’s kind of a wild idea, but if you’re free to break away for a few weeks, consider making the trip. Climb Kilimanjaro, visit the Serengeti, relax on Zanzibar, and spend a couple of weeks programming with me and a couple of Tanzanian guys. We’ll have fun.

As a refugee of the cubicle jungle where the project status overlords patrolled the aisles, one of the most exciting aspects running a Ruby consultancy is using all the neat tools keep a virtual development team at cruising speed. This talk provides a quick overview for many of the (often free) tools available to distributed Ruby teams and how you can integrate them to improve communication and efficiency.

Source control
While Subversion has been the standard for many years, there is a groundswell of support for Git. Originally created by Linus Torvalds for managing the Linux kernel, Git has become popular due to its improved branch management and merging support as well as its distributed architecture which enables each developer to have local versioning (for working offline or on larger efforts in parallel to the rest of the team). The launch of Github (think MySpace for developers, Git has exploded in the Ruby community offering free hosting for Open Source projects and even a Gem Server for hosting uby Gems). Lighthouse from the guys at AlternateIdea is another popular Rails-based issue tracker and now the official tracker for Rails core.

Issue Tracking
While there are many issue trackers out there, an upstart Open Source Rails-based project named Redmine offers powerfully extensible issue tracking and source control repository integration. Rubyists can also extend the application with plugins.

Time keeping
SlimTimer and Freshbooks offer powerful tools for team members to log time and clients to see real-time project burn rates.

Tying it all together, real-time communication and workstreaming

For constant, asynchronous communication it’s hard to beat Campfire from 37 signals. Free for up to 4 simultaneous chatters, Campfire provides a quick-and-easy way to communicate with team members and clients without the formality or noise of email. The best part about Campfire is the Tinder gem from the boys at Collective Idea. Tinder is an unofficial api for Campfire that allows you to announce source control commits, builds, and other work events directly into the chat room. GitHub offers Tinder/Campfire support out of the box. Just enter your Campfire room configuration and each SCM commit will be announced in your room. Tinder can be called from Capistrano to do the same thing for each deployment event. GitHub also supports Twitter and Lighthouse integration.
