Jo is a JavaScript framework for HTML5 capable browsers and devices. It was originally designed to work on mobile platforms as a GUI and light data layer on top of PhoneGap.

Since its creation, Jo has also been tested successfully as a lightweight framework for mobile browsers, newer desktop browsers, and even Dashboard widgets. Jo is under a friendly OpenBSD License. Minified JavaScript is just over 8K with no dependancies.

There are some great JavaScript testing frameworks out there. Many only work from within a browser. Most don’t support testing asynchronous code like event callbacks. Some have syntax that’s hard for JS developers or IDEs to understand.

Jasmine is a JavaScript testing framework. It’s heavily influenced by, and borrows the best parts of, ScrewUnit, JSSpec, JSpec, and of course RSpec. Jasmine is not tied to any browser, framework, platform, or host language. It work anywhere JavaScript can run, including browsers, servers, phones, etc.

One of the more interesting and fun aspects of iPad usage is the ability to effect change in a webpage by swiping a finger across the screen of the iPad. For example, swiping to the left to navigate to the next page in a series of pages, or swiping to display the next image in a series of images. For iPad users, these actions are intuitive and natural.

However, for those who compose webpages, adding touch detection to a page can be a challenging and difficult process. No more. The information presented on Padilicious: Add Finger-Swipe Support to Webpages, will make it easy to add touch sensing to your pages, requiring only a minimum of JavaScript coding on your part.

jQuery Mobile is a Touch-Optimized Web Framework for Smartphones & Tablets. It is a unified user interface system across all popular mobile device platforms, built on the rock-solid jQuery and jQuery UI foundation. Its lightweight code is built with progressive enhancement, and has a flexible, easily themeable design.

The aim is to provide tools to build dynamic touch interfaces that will adapt gracefully to a range of device form factors. The system will include both layouts (lists, detail panes, overlays) and a rich set of form controls and UI widgets (toggles, sliders, tabs). jQuery Mobile is now under development for late 2010.

HTML5 Boilerplate is the professional badass’s base HTML/CSS/JS template for a fast, robust and future-proof site.

After more than two years in iterative development, you get the best of the best practices baked in: cross-browser normalization, performance optimizations, even optional features like cross-domain ajax and flash. A starter apache .htaccess config file hooks you the eff up with caching rules and preps your site to serve HTML5 video, use @font-face, and get your gzip zipple on.

Boilerplate is not a framework, nor does it prescribe any philosophy of development, it’s just got some tricks to get your project off the ground quickly and right-footed.

OpenStack is an Innovative, open source cloud computing software for building reliable cloud infrastructure. The goal of OpenStack is to allow any organization to create and offer cloud computing capabilities using open source software running on standard hardware.

OpenStack Compute is software for automatically creating and managing large groups of virtual private servers. OpenStack Storage is software for creating redundant, scalable object storage using clusters of commodity servers to store terabytes or even petabytes of data.

All of the code for OpenStack is freely available under the Apache 2.0 license. Anyone can run it, build on it, or submit changes back to the project. They strongly believe that an open development model is the only way to foster badly-needed cloud standards, remove the fear of proprietary lock-in for cloud customers, and create a large ecosystem that spans cloud providers.

If you’re building a multi-language website or app, you probably use language files. When you change content in one language file, you need to remember to update the other language files. Even with source control, this can get messy pretty quickly if you have many languages, many translators or a large site.

String was built to keep things organized. It can manage your language files – from PHP to PO to Rails to iPhone apps. Import and export easily. You can now easily add languages and sections to your site. You can also invite users and control permissions. String is free, with no project limits. Invite as many users as you like. You’re free to extract all your data and close your project at any time.

Each language, and the countries that speak that language, have different expectations when it comes to how numbers (including currency and percentages) and dates should appear.

Obviously, each language has different names for the days of the week and the months of the year. But they also have different expectations to the structure of dates, such what order the day, month and year are in. In number formatting, not only does the character used to deliniate number groupings and the decimal portion, but the placement of those characters differ.

A user using an application should be able to read and write dates and numbers in the format they are accustomed to. The jQuery Globalization plugin makes this possible, providing an API to convert user-entered numbers and dates in their own format into real numbers and dates, and conversely, to format numbers and dates into that format.
