CocoaPods is the dependency manager for Cocoa projects. It has thousands of libraries and can help you scale your projects elegantly.

Think of it as PHP's Composer, but for iOS/Mac apps! My team Alpha at AOL used this for building the Pip messaging app.

FLEX (Flipboard Explorer) is a set of in-app debugging and exploration tools for iOS development. When presented, FLEX shows a toolbar that lives in a window above your application. From this toolbar, you can view and modify nearly every piece of state in your running application.

So your working on your WordPress theme, and need to include some javascript or css, just throw it in the header or footer right? Well, actually Wordpress has it's own preferred way of including js and css. If you follow their best practices, you can avoid the risk of conflicting with other themes and plugins.

I recently posted a link to "Beautiful Buttons for Twitter Bootstrap" which allows you to pick different colors for your bootstrap elements, but this goes a step further. It provides examples of how easy it is to swap out color palettes and fonts for Bootstrap.

The boilerplate includes the following libraries: ASIHTTPRequest, JSONKit, SVProgressHUD and few others.

It also includes helper classes for: - HTTP requests and an image cache (both in-memory and disk-based). - UITableViews and UITableViewCells: fast scrolling, async images, pull-down-to-refresh, swipeable cells. Maps and locations: directions between two points, autocomplete a location, etc.

Note: Some of the libraries here may become obsolete once iOS 5 is released, see: http://news.ycombinator.com/item?id=2996785

"Some fantastic and useful libraries have been written for CodeIgniter, but they remain scattered around the internet on blogs, wikis, forums, and github.

"Creating themes for Tumblr sucks.

It’s a testament to the passion developers and designers feel for Tumblr that so many great themes exist – despite the complete lack of tools. No matter how you tackle it, developing a theme involves a time-consuming mess of manual copying and pasting, saving, testing, and copying and pasting again.

TumblrThemr solves this problem, letting you develop navigable themes locally using real data from your Tumblr blog."

Matchbox is a modular system, which means you can group your controllers, models and views for a specific section of the site together. There's a new competitor called Modular Separation. Modular Separation is purely PHP 5 which gives it a slight edge over Matchbox from the get-go as it can leave out a lot of the extra PHP 4 support and go right for the much cleaner & quicker full OOP approach. It also includes 404 routing.

Popular CodeIgniter PyroCMS has now been converted to use Modular Separation and it has shaved a few 100ths of a second off here and there. I am not suggestion you drop Matchbox right now, but give it a try if you are starting a new project.

"Stop. Ok, I feel your frustration. You're a web developer and you're ready to tear your hair out because you have to support Internet Explorer 6, but, to put it tactfully, IE6 doesn't support you. You've spent hours on it, but you just can't seem to get your layout right. I can empathize. I can also help."
