With practice, this new mental map of color will become instinctive: you’ll likely find that it is much easier to create and manipulate color specified in HSL in your stylesheet code than hex or RGB. See also Three Ways You Should Be Using HSL Color In Your Site Today.

The Flipboard Explorer, or FLEX, is a component that you can easily drop into any iOS project. When presented, FLEX shows a debugging toolbar that lives in a window above your app. From this toolbar, you can view and modify nearly every piece of state in the application. Unlike many other debugging tools, FLEX works entirely inside your app, so you donʼt need to be connected to LLDB/Xcode or a different remote debugging server....

The Wilderness It’s a period of time where I’m pretty lost, and I don’t know what to do. I have feature lists, I have open bugs to fix, and I have an outline of where the app is going. But I feel mentally incapacitated, like I’m getting nothing done. I call this “The Wilderness”.

JSON Generator – tool for generating random JSON data We’ve all faced the problem of lack of information in our app. All interfaces seem lifeless and empty. Debugging with no data is also not simple.

JSON Generator was created in order to help with this....

Documenting in Xcode with HeaderDoc Tutorial | Ray Wenderlich When Xcode 5 and iOS 7 were announced, a small addition was mentioned that most people might have missed: HeaderDoc. (…) In addition, Xcode parses HeaderDoc-style comments behind the scenes to automatically present your documentation in quick look panels.

There is, however, old wisdom — perhaps from an earlier version of the Mac HIG — that says how to create error messages: they should be of the form “Can’t x because of y.” They may optionally include additional detail and/or recovery steps. “Can’t x because of y. Something is true. Try a thing.” A similar form is this: “Noun can’t x because y.” (As in “‘Downloaded.app’ can’t be opened because it is from an unidentified developer....

Uncle Bob Martin walks through the “Prime Factors” kata in Java (29m06s) to illustrate the concept of Transformation Priority Premise as a way to address the common complaint about TDD: the brainlessness “As the tests get more specific, the code gets more generic.” … and “here’s the list of transformations” (47m53s): So what are these transformations? Perhaps we can make a list of them: ({}–>nil) no code at all->code that employs nil (nil->constant) (constant->constant+) a simple constant to a more complex constant (constant->scalar) replacing a constant with a variable or an argument (statement->statements) adding more unconditional statements....

Convert Photoshop Drop Shadows to CSS3 Box and Text Shadows This tool creates CSS3 Box Shadows based off of Photoshop Drop Shadow settings. After stumbling upon the Recreating Photoshop Drop Shadows in CSS3 and Compass article by Grady Kuhnline, I wanted to build a tool that would allow the rest of us not using Compass to have the same ability to convert for CSS3.
