| # Hosted Developer Tools {#hosted-developer-tools} | [Think Stats](http://greenteapress.com/thinkstats/html/index.html) |
| **Programming** | |
| Programming is valuable skill for manipulating and displaying data. | |
| Basic tutorials for a variety of languages are available for free online or you can learn interactively with websites like [Codecademy for JavaScript](http://www.codecademy.com/#!/exercises/0), [Learn Python](http://www.learnpython.org/) or [Try Ruby](http://tryruby.org/) | |
| For web applications and visualisations, you'll need a basic understanding of JavaScript in order to configure pre made libraries like jQuery. A good source for Javascript information is the [Mozilla Development Network Javascript Page](https://developer.mozilla.org/en/JavaScript) | |
| **Accessibility/User Experience** | |
| Following accessibility guidelines not only make a application accessible but make it a better experience for all users! Even if not making an app, good to consider these things to do and not do when designing for humans: [http://www.w3.org/TR/WCAG/](http://www.w3.org/TR/WCAG/) | |
| # Developer Tools For Your Computer {#developer-tools-for-your-computer} | |
| No matter what kind of application you have for the data, there are many tools you can use to better collaborate and manage your project. | |
| ### Source Control | |
| Using a version control system like Git or Subversion allows you to keep many different versions of what you have been working on so you can collaborate with others or simply back up your files so you don't lose them! | |
| [](http://progit.org/book/) | |
| [http://progit.org/book/](http://progit.org/book/) | |

| [http://code.google.com/p/tortoisegit/](http://code.google.com/p/tortoisegit/) | |
| ### Task Tracking | |
| Issue/task trackers allow you to outline the tasks required for your project and assign them to people to do. | |
| [Trello](https://trello.com/) and [Workflowy](https://workflowy.com/) are free, lightweight project management tools suitable for a rapid project! | |
| ## Hosted Developer Tools {#hosted-developer-tools} | |
| Can get many tools (source control, issue tracking) combined into one service cloud hosted so there's no setup required. | |
| ### Github | |
| Git obviously but svn/hg interfaces are also available. Provide their own GUI for Windows/OSX or use a variety of Git capable tools | |
| ### Sourceforge | ### Sourceforge |
| Subversion, Git, Mercurial, Bazaar, CVS, issue tracker, wiki, release file downloads. Unlimited free use for open source projects. | Subversion, Git, Mercurial, Bazaar, CVS, issue tracker, wiki, release file downloads. Unlimited free use for open source projects. |

| HowTo.gov has a bunch of api resources about choosing SOAP vs. REST etc. http://www.howto.gov/mobile/apis-in-government | |
| API documentation is important too! Traditionally for SOAP APIs, you use WSDL but for REST try [Swagger](http://swagger.wordnik.com/) or [iodocs](https://github.com/mashery/iodocs) | |
| Many web app frameworks can generate the documentation for you. For example Symfony for PHP http://symfony.com/ https://github.com/FriendsOfSymfony/FOSRestBundle http://williamdurand.fr/2012/08/02/rest-apis-with-symfony2-the-right-way/ https://github.com/nelmio/NelmioApiDocBundle | |
