1) Flash CS5 – At the moment is probably the most complete solution.  The packager for iOS allows you to compile apps on the windows platform.  If you’ve been using flash you can rejoice in Apple’s latest policy, it performs well, but don’t expect highest performance games, and Papervision to run in here.  No mac required. 2) Airplay SDK – The airplay SDK allows you to create games, and sign your app on Windows PC’s.  I have not tested this solution, but apparently many apps have been created this way. Both these solutions can compile to code that is native to the iPhone right on your windows PC and many apps available in the app store have been created using them. 3) Unity 3D – Game development engine and editor that utilizes Boo and C# and the editor works on both Windows and Mac. 4) Stonetrip S3D – Game develop engine and editor utilizing LUA, the editor runs within Windows. These game engines allow you to develop your apps on Windows, but you’ll need a Mac to test/compile. 3) Appcelerator Titanium – This is a good solution, and has a very popular and vibrant community.  Apps are limited in performance because while they can be compiled as native apps and sent into the app store they are html/javascript based. 4) Genuitec MobiOne – This is an interface designer that uses the Phonegap framework to deliver native functionality.  It only runs on windows.  HTML/Javascript based. These solutions allow you to create apps using web technologies (HTML/CSS/Javascript) and then run them through an Objective-C framework that responds to actions within a UIWebView, thus allowing you to access native functionality on the iPhone.  These frameworks are free. 5)Dragonfire SDK – An interesting option that allows you to develop apps using their SDK on windows.  Then you send them your uncompiled source which they compile and you download the compiled iOS application file.  I’ve been asked if this means they get a copy of your uncompiled source code.. I couldn’t tell you that, I just know that you have to upload your code for compiliation to their website — but hey you wanted to develop iPhone apps on Windows.  Overall this is a wrapper, I like the syntax and it’s pretty popular so I’ll mention it.

The concept is called “Window to the World,” and it allows the user to interact with the world outside the window by tracing and drawing with his or her fingers on the window in an augmented reality kind of way

In mobile browsers, you need to be especially careful about using timers because of the battery consumption. If you need to use many high-frequency timers at the same time, try to manage them using only one timer that will launch different behaviors from the same process.

The first question we need to ask ourselves is, what happens when our web page goes to the background because the user switches focus to another application (in multitasking operating systems) or opens or browses to another tab or window? Another problem is what happens when the phone goes to sleep (because of the user’s inactivity while the script is executing). The behavior of timers can be a little tricky in these situations.Yet another problem is that timers execute on the same thread as the main script. If our script is taking too much processor time (a normal situation with large scripts on low- and mid-end devices), our timers will be delayed until some spare execution time is found.If we use a low frequency for the timer (for example, 10 milliseconds), the timer will generally have problems meeting the timetable.Remember that the JavaScript execution time depends a lot on the device hardware and the browser’s engine. Even if they’re running the same operating system, like Android, execution times can differ: for example, an HTC G1 will be much slower than a Nexus One with a 1-Ghz processor.

As shown in Figure 4, the real times are very different on different devices. On low- and mid-end devices, if they work at all, the result is far from our 200 ms intention—some low-end devices don’t even accept timers with a frequency of less than 1 second.

Want to write apps for OSX, the iPhone or the iPad? You can learn JavaScript and use a frameworks like PhoneGap or Titanium. Or you can learn the official language of Apple operating systems:  Objective-C. The debate over whether to build mobile apps in JavaScript or Objective-C is beyond the scope of this blog post. But if you want to learn Objective-C, these resources will get you started.

Leap Motion – which is basically Kinect on steroids – is a tiny sensor that lets you control your Windows, Mac, or Linux PC with precise mid-air gestures. The company wants to launch with as much great software support as possible, and Google Earth is a big feather in that cap. With version 7.1 for desktops (available now) you can now use Leap to zoom through big cities, rustic boroughs, and Arctic tundra like you’re Obi Wan Kenobi.

ZoomIt is screen zoom and annotation tool for technical presentations that include application demonstrations. ZoomIt runs unobtrusively in the tray and activates with customizable hotkeys to zoom in on an area of the screen, move around while zoomed, and draw on the zoomed image. I wrote ZoomIt to fit my specific needs and use it in all my presentations.ZoomIt works on all versions of Windows and you can use pen input for ZoomIt drawing on tablet PCs

If you’re a Windows user looking for free online storage, three services stand out from the rest. Although Dropbox, SkyDrive, and Google Drive are superficially similar, there are some big differences. Here’s what to look for.
