pocode: C++ library for production of interactive media across multiple platforms

pocode is an open-source C++ library designed by Potion for the production of interactive media across multiple platforms.

pocode provides a robust, high-performance software infrastructure that allows for the creation of all types of software, from simple visual sketches to elegant mobile apps to entire software applications.

pocode is much more than a graphics library. pocode allows creative coders to construct complex interactive software. Thanks to pocode’s object-oriented architecture, applications stay organized and take care of themselves. pocoders don’t have to worry about the intricacies of event routing, the frustrations of font loading or the pitfalls of porting between platforms. All of these processes are performed automatically.

pocode is also an open system that allows pocoders to dive deep into the software architecture and implement alternative methods of their own. pocoders can extend pocode with their own poObjects, and share them with other pocoders. Since all poObjects fit within pocode’s object-oriented framework, shared poObjects can easily be incorporated into new applications, even across platforms.

Lager: logging framework for Erlang/OTP

Lager (as in the beer) is a logging framework for Erlang. Its purpose is to provide a more traditional way to perform logging in an erlang application that plays nicely with traditional UNIX logging tools like logrotate and syslog.

Treesaver: JavaScript framework for magazine-style layouts

Treesaver is a JavaScript framework for creating magazine-style layouts that dynamically adapt to a wide variety of browsers and devices. Designers use standards-compliant HTML and CSS for both content and design, no JavaScript programming is required.

Key features and aspects:

  • Fast and compact: The JavaScript is under 25K gzipped (important for mobile).
  • Highly compatible: Works with most modern browsers, and degrades gracefully for older browsers (or those with JavaScript disabled).
  • Liberally licensed: Dual-licensed as MIT and GPL.

What Treesaver is not

  • Complete: The framework is still quite immature. There are still a lot of bugs that need to be fixed.
  • WYSIWYG: Treesaver is not designed to provide designers with the ability to create pixel-perfect layouts -- quite the opposite in fact. Treesaver is designed to give designers the ability to create general design guidelines, which are then used to quickly construct a layout appropriate to the current browser and device.
  • Suited for all content: Treesaver currently works best with simply-formatted text and images. Complex tables, videos, and JavaScript widgets might work, or they might not. Once again, the framework is not yet complete.

Three20: collection of iPhone UI classes

Three20 is an iPhone development library. It's the code that powers the Facebook iPhone app and many other apps in the app store.

Core

Think of core as your swiss-army knife of Objective-C development. You should take some time to familiarize yourself with its features.

With the Three20 Core you can

  • generate md5 hashes from NSData objects,
  • extend the logging and debug capabilities of Xcode,
  • compare two version strings (is 3.0 older than 3.1?),
  • create non-retaining NSArrays and NSDictionaries for delegate use,
  • strip HTML tags from strings,
  • safely add non-empty, non-nil strings to NSDictionaries,
  • and format dates in relative time (5 hours ago).

You'll find all of these methods in the Three20 Xcode project in the
Global => Core and Global => Additions => Core groups.

Network

If you're building an app that uses a web-based API, Three20's Network component is going to make your job easier. Three20 supports disk and memory network caching. There is also a layer built upon requests that makes it easy to process the response data.

UI

A growing set of common views and controllers is available within the Three20 UI. The well-known Facebook photo browser/thumbnail viewer is one such controller.

libimobiledevice: library to support iPhone, iPod Touch and iPad devices on Linux

0outlook

libimobiledevice is a software library that talks the protocols to support iPhone®, iPod Touch® and iPad® devices on Linux. Unlike other projects, it does not depend on using any existing proprietary libraries and does not require jailbreaking. It allows other software to easily access the device's filesystem, retrieve information about the device and it's internals, backup/restore the device, manage SpringBoard® icons, manage installed applications, retrieve addressbook/calendars/notes and bookmarks and synchronize music and video to the device. The library is in development since August 2007 with the goal to bring support for these devices to the Linux Desktop.
