LongJump Launches Cloud Database Service

 

LongJump, offering “Database-as-a-Service (DaaS)” that allows the more technically literate to build applications with databases in the “cloud” (i.e. stored on LongJump’s servers).

Most of LongJump’s value has hitherto been relevant for the type of people who don’t have the expertise or initiative necessary to develop DB applications

LongJump, with access to its REST-based API included, costs $24.95 per user per month, or $19.95 per user per month with a 12-month commitment. Competitor SalesForce has a similar type of API but one which is SOAP-based. LongJump’s offering differs from Amazon’s newly released SimpleDB service by functioning as a MySQL-based relational database service, whereas SimpleDB possesses its own architecture. For more information on LongJump’s API, check out the company’s API guide.

The Stopwatch Class in .NET 2.0

 

Do you ever find yourself using DateTime to time a section of code?  If you do, you should look at the System.Diagnostics.Stopwatch class that was introduced in the 2.0 framework.

  Stopwatch stopwatch = new Stopwatch();
  stopwatch.Start();

  Thread.Sleep( 1968 ); // Perform a long process 

  stopwatch.Stop();
  Console.WriteLine( “This process took {0} ms”, stopwatch.ElapsedMilliseconds );

The Stopwatch measures elapsed time by counting timer ticks in the underlying timer mechanism. If the installed hardware and operating system support a high-resolution performance counter, then the Stopwatch class uses that counter to measure elapsed time. Otherwise, the Stopwatch class uses the system timer to measure elapsed time. Use the Frequency and IsHighResolution fields to determine the precision and resolution of the Stopwatch timing implementation.

Microsoft Sync Framework Support in Visual Studio 2008

 

Microsoft Sync Framework is transport agnostic platform for automatic data synchronization across different types of datasources. It can be used for occasionally connected applications (smart clients) and p2p supplications. Previously we had to either use SQL server merge replication or write own synchronization framework. And now we have a solution from Microsoft that looks very promising. There is a good documentation for this on MSDN, if you need more details or code samples you will find them there.

While playing with Visual Studio 2008, I accidentally found new item type called “Local Database Cache”. I turned out that this is really Microsoft Sync Framework integration with Visual Studio.
