  • From users to developers, mobile applications used to be (not so long ago) uninteresting. Complicated flows, non-intuitive screens and limited features available used to discourage anyone. PDAs had a poor user interface with limited colors (the first ones were only black and white). It was very complicated and boring to write any code for it. Cell phones used to be a device where you could make and receive phone calls. Eventually you could play some games. But you know w...See More

  • Chris shows us how to make sure that your app is not only cross-platform, but international and global as well.
  • In all but the simplest applications, data is stored in a central location and accessed over a network.However, in many scenarios, distributed applications can not assume a certain kind of network connection, both in terms of performance and reliability. In scenarios where users access their applications on mobile PCs, network connections may not be available at all. This introduces relatively complex data access scenarios with which modern applications need to cope.

  • Growing up in the 80s, two of the concepts that drew me in to computer science were computers that were small enough to take with you (called “Luggables” then) and displays that were thin enough to hang on a wall.Technology has come a long way in that time-and the Ultra-Mobile class of personal computers that run the Windows Vista™ operating system is a great example of that progress. So what is a UMPC and why would I be interested in writing an application that is optimized for it?

  • I think we’re making progress toward the goal of bending computers to conform to human factors rather than bending my human factors to conform to the way computers accept input.Ultimately, our brains will be plugged directly into “the grid,” but until then, users still have to learn how to type, control a mouse, and press buttons in certain sequences. The arrival of the Windows Vista™ operating system with Microsoft® Windows® Tablet and Touch Technology is another step t...See More
