Hi, I have a problem mapping the following situation from v1 to v2 of a core data model. In v1 of the model I had an entity named book with an attribute author. There I saved the first and last name of the author and even first and last names of several authors. Very poor design I know, but that's how it was. In v2 of the model I made...

Update Luckily, the code that WebKit uses to make this control draws onto a canvas using basic drawing operations, so it shouldn't be too hard to convert into a Cocoa control. This is what I have so far: I'll update here again once I get it finished. Original question I don't know what to call this sort of control, so I'll show pictu...

I ran into this trying to throw together a simple Automator script to combine several one-page PDF files. I had 88 files to combine, each just about exactly 300KB, so I expected the final product to be about 30MB; the resulting PDF file, using the Combine PDFs Automator action, was 300+MB. Poking around, the Automator action uses a Pyth...

After reading the iPhone Human Interface Guidelines, I notice there's little mention of checkboxes in the style that one may encounter them on the desktop or web. Checkboxes are generally handled by UISwitchs on the iPhone, but for an app I'm presently working on, they're really not the right control. Instead, the control you'll see in ...
