  Happy Pi Day! — Add a Pie to the Ring Graph

  For those of us in the U.S. with a geekiness toward math March 15, 2015 at 9:26:53 is going to be the best pi day ever. As the date in the American calendar format is 3/14/15, the closest approximation to pi the mm dd yy hh:mm:ss format can have. To celebrate this, I’m going to […]

  The Joys of Beta Swift: as Versus as! and Why I Avoid Betas

  It came to my attention this week there’s a big change to Swift code on the way. It doesn’t look big though: it is the difference between as and as!. The keyword as is the conversion operator. Usually type or class are easily defined like this: But there are times you get things like this […]

  The Joys of Beta Swift: More with Optionals and the “does not have a member named” error

  We’ve had another change to the Swift compiler that was brought to my attention by an astute reader. I was aware of it, and you’ll notice I even used it in the last few posts, but I really should have warned people about it, and got it fixed. Back in my post on Adding an […]

  The Joys of Beta Swift: A Change to Outlets

  I went to open the pizza demo to get ready for my next post and was greeted by 10 compiler error messages, all the same. ‘IBOutlet’ property has non-optional type ‘UILabel’ Just after I finished the optionals post, It turns out there a change in Beta 4. Before Beta 4, and as described in Apple’s […]

  The Swift Swift Tutorial: Oops! Why your Pizza Prices Don’t Update

  There are plenty of people who say if you make a mistake you will lose your reputation, so It’s best to hide your mistakes. I’m not one of those people. If I goof I’d rather get the situation fixed and get everything working again. I like that kind of transparency and integrity. So — I […]

  From Apple to Raspberry Pi: How to Make a List Box (Somewhat) Useful

  

  In the Popper’s Penguin application, I’d like to take my data, display it, and be able to select it. If I was doing this in Xcode, I’d use an UITableView to do exactly that. UITableViews are more advanced than what I want, as they respond to gestures. I don’t need the delete button in the […]

  SlippyFlippy 1.1: The Bug Hunt

  

  Since my last post I got my first one-star review of SlippyFlippyPenguin. The Hard Mode bug  did it. Someone else can’t start the game in hard mode. In my last entry, I set up  a timer to fix what I thought is a user-related problem with the game. In the process, I found the real bug. […]

  SlippyFlippy 1.1: Making a High and Low Score Indicator

  

  This is the first of my improvements to the SlippyFlippy penguin game.  While this may not make sense since I have not posted all the game code yet, it might help those trying to come up with some of these solutions for their own games. While playing against  some of my friends on our different […]

  Bass ackwards with Objective C.

  It drives me nuts, thinking backwards. in Java or C++ or C, functions and methods are simple. They’re close to what I did in Pascal a quarter century ago: and then the call would be No biggie. If sampleMethod was in a an object I was calling, But Objective C turned things around. Definitions are […]
