Fractal is a tool to help you build and document web component libraries, and then integrate them into your projects.

Component (or pattern) libraries are a way of designing and building websites in a modular fashion, breaking up the UI into small, reusable chunks that can then later be assembled in a variety of ways to build anything from larger components right up to whole pages.

Fractal helps you assemble, preview and document website component libraries, and then integrate them into your web sites, apps and build processes to create joined up, ‘living’ projects.

Fractal can be run from the command line or integrated into your project via its API.

A source-control branching model, where developers collaborate on code in a single branch called ‘trunk’ *, resist any pressure to create other long-lived development branches by employing documented techniques, avoid merge hell, do not break the build, and live happily ever after.

Floobits brings real-time collaborative editing to text editors, IDEs. Collaborative text editors and screen sharing solutions usually suffer from the following problems:

Users are confined to looking at the same thing.
Only one user can edit at a time.
One person is usually stuck in an unfamiliar editor.
Only 2 people can work at a time.

We started building Floobits for ourselves to address these concerns. Floobits allows multiple users to simultaneously edit any file using the text editors they already know.

RAW is an open web tool to create custom vector-based visualizations on top of the amazing d3.js library.

Primarily conceived as a tool for designers and vis geeks, RAW aims at providing a missing link between spreadsheet applications (e.g. Microsoft Excel, Apple Numbers, Google Docs, OpenRefine, …) and vector graphics editors (e.g. Adobe Illustrator, Inkscape, …).

RAW works with tabular data (e.g. spreadhseets and comma-separated values) as well as with copied-and-pasted texts from other applications (e.g. Microsoft Excel, TextWrangler, TextEdit, …). Based on the SVG format, visualizations can be easily edited with vector graphics applications for further refinements, or directly embedded into web pages.

Knowing the need of working with sensitive information, the data uploaded to RAW is processed only by the web browser: no server-side operations or storages are performed and no one will see, touch or copy your data!
