SuperCollider. Beginning Java EE6: Source Code Repository. Ry Management with Objective C / Cocoa / iPhone | memo.tv. Now that the iPhone SDK is out, iPhone/iPod Touch has sold millions and the App Store is pretty popular, there are many people taking to iPhone and Cocoa Touch development. While the SDK is very well designed and pretty quick to get into, the biggest hurdle is usually the unique language that Apple (and previously NextStep) chose for its development on OSX and iPhone: Objective C.
At first glance it looks hideous and unlike anything most people using C based syntax are used to (C, C++, ActionScript, JavaScript, Java, C#, GLSL etc.). But once you get your head around it, you really come to love it and understand why this choice was made. One of the biggest obstacles most people have to get their head around when they first start Objective C / Cocoa development is the memory management - and it's actually very beautiful when it finally dawns on you how simple it really is (though this may take a couple of proper projects!).

I recently decided to buy a MacBook Air as a travel machine to use during speaking engagments. After much deliberation, I decided to go for the maximum-specification 11-inch model, since portability is the most important factor for me (and I have plenty of desktop Macs around the house as primary machines). I’m thrilled with it, and thought I’d share a few observations and screenshots of various apps running on the Air. If you’re considering buying an Air, my advice would be this: unless you plan to use it as your main/primary work machine, buy the 11-inch model (indeed, unless you’re doing anything particularly intensive – such as enormous local compilations, audio or video editing, and such – you could certainly use the 11-inch as a primary machine too).
If you’re interested, you can see some unboxing photos of the 11-inch Air here. Performance I went with the 1.6GHz / 4GB RAM/ 128GB SSD spec. Below are a few casual indicative figures for app launch times, achieved consistently. Storage. Read Our Magazines.

In the real world, most things we encounter are non-deterministic. There are always factors we can't control or measure, and most systems have a human element. We are at the mercy of whim and emotion, and that's hard for a lot of programmers to deal with. Our fellow humans's decisions are decidedly non-deterministic and hard to predict, as are ours (though we usually don't notice this trait quite as much in ourselves).
You may have noticed that I haven't had much time to write lately. I've been exceedingly busy of late, even by my own standards. Although a lot of my time is being spent writing and debugging software, I've also been involved with some very non-deterministic problems as a result of my involvement with some large, complex development projects. Probably the biggest non-programming problem that I've had to deal with lately, which most of my industry peers and nearly all of our clients are dealing with also, is finding good, experienced, reliable developers to staff projects.
