The Microsoft Sync Framework provides a platform for taking web services and databases offline. In addition, it provides optimized P2P sync of any type of file including contacts, music, videos, images and settings. The extensible framework includes built-in support for synchronizing databases, NTFS/FAT file systems, FeedSync compliant feeds (formerly known as Simple Sharing Extensions), devices and web services.

design and build your application as a .NET client application, then assign the portions of the application to run on the server and the client tiers late in the development process. The compiler creates cross-browser JavaScript for the client tier, web services for the server tier, and communication, serialization, synchronization, security, and other boilerplate code to tie the tiers together.

The biggest question left unanswered in my mind is the role state will play in software of the future.

The biggest question left unanswered in my mind is the role state will play in software of the future. That seems like an absurd statement, or a naïve one at the very least. State is everywhere: The values held in memory. Data locally on disk. Data in-flight that is being sent over a network. Data stored in the cloud, including on a database, remote filesystem, etc. Certainly all of these kinds of state will continue to exist far into the future. Data is king, and is one major factor that will drive the shift to parallel computing. The question then is how will concurrent programs interact with this state, read and mutate it, and what isolation and synchronization mechanisms are necessary to do so?
-
Many programs have ample gratuitous dependencies, simply because of the habits we’ve grown accustomed to over 30 odd years of imperative programming. Our education, mental models, books, best-of-breed algorithms, libraries, and languages all push us in this direction. We like to scribble intermediary state into shared variables because it’s simple to do so and because it maps to our von Neumann model of how the computer works.

We need to get rid of these gratuitous dependencies. Merely papering over them with a transaction—making them “safe”—doesn’t do anything to improve the natural parallelism that a program contains. It just ensures it doesn’t crash. Sure, that’s plenty important, but providing programming models and patterns to eliminate the gratuitous dependencies also achieves the goal of not crashing but with the added benefit of actually improving scalability too. Transactions have worked so well in enabling automatic parallelism in databases because the basic model itself (without transactions) already implies natural isolation among queries. Transactions break down and scalability suffers for programs that aren’t architected in this way. We should learn from the experience of the database community in this regard
-
There will always be hidden mutation of shared state inside lower level system components. These are often called “benevolent side-effects,” thanks to Hoare, and apply to things like lazy initialization and memorization caches. These will be done by concurrency ninjas who understand locks. And their effects will be isolated by convention.
-
Even with all of this support, we’d be left with an ecosystem of libraries like the .NET Framework itself which have been built atop a fundamentally mutable and imperative system. The path forward here is less clear to me, although having the ability to retain a mutable model within pockets of guaranteed isolation certainly makes me think the libraries are salvageable. Thankfully, the shift will likely be very gradual, and the pieces that pose substantial problems can be rewritten in place incrementally over time. But we need the fundamental language and type system support first.

As a security sandbox, the iPhone OS permits only one third-party application to run at a time, and not in the background.

adding some useful Bluetooth profiles that supported stereo headsets, data synchronization, or the ability to implement multiplayer games would be usefu
-
iPhone OS 3, that provides some of the missing features mentioned here, such as the A2DP profile for Bluetooth, voice recording, and copy-and-paste.
-
The OS now supports the use of accessories connected to the iPhone either through its 30-pin docking connector or wirelessly via Bluetooth. Now that the device has been "opened", you can expect an entire ecosystem to build up around the device, much like the iPod has.
-
A client-server mechanism provides access to low-level system resources, and in fact the kernel itself is a server that parcels out resources to those applications that need them. This transaction scheme allows applications to exchange data without requiring direct access to the OS space.

Handango has managed the wide-scale distribution of Nokia applications. In February, Nokia announced plans to launch its Ovi Store, which sells applications, videos, games, pod-casts and other content, similar to Apple's App Store. The store will be accessible by Nokia S60 smartphones in May.

Non-standard Symbian C++ has steep learning curve, with special idioms to master. Large number of Symbian APIs to learn, since it contains hundreds of classes and thousands of member functions.

BlackBerry Device Software has enhanced the capabilities of the platform with its own Java virtual machine (JVM), along with new Java classes that offer multitasking capabilities and UI enhancements to go beyond the capabilities of Java ME.

You can also take existing Java ME code and add specific BlackBerry classes to make a hybrid Java ME application
-
don't intermix MIDP 2.0 and BlackBerry API calls that perform either screen drawing or application management.

The catch to writing an application that uses BlackBerry API extensions is that it ties the application this smartphone. However, this is no worse than using the unique Java classes found in Google's Android.

For non-Exchange users, Apple's MobileMe online service, after some fits and starts in 2008, now supports the push of e-mails and changes to the calendar and contacts.

the SDK provides Dashcode, which is a framework based on a Web page composed of HTML and Javascript. You can use DashCode's simulator to write and test your web application. You can also use several other third-party frameworks to write web applications, and debug these with Aptanna Studio's tools.

ability to both browse and manage multiple IM conversations. On the other hand, such heavy use of the smartphone's CPU shortens battery life significantly. Maybe Apple is on to something in limiting the number of applications that the platform can run.

On the positive side, the Android APIs support a touch interface (and the G1 has a capacitive touch screen), but not any multi-touch gestures.
-
The advantage to Android's use of a different bytecode interpreter is that the DVM was designed so that multiple instances of it can run, each in their own protected memory space, and each executing an application. While this approach offers stability and a robust environment for running multiple applications, it does so at the expense of compatibility with Java ME applications.

Seasoned Java programmers will find the Android SDK an amalgam of Java SE and Java ME methods and classes, along with unique new ones
