From Yahoo:

Microsoft have been looking at the question of quality assurance and this week is presenting a tool uses techniques used in capacity planning and performance modelling.The Spec Explorer 2010 tool, funnily enough known as Spec Explorer, can be obtained from the Microsoft DevLabs website.

High quality testing of systems and applications is one of the prime challenges in the application development process. The Spec Explorer tool issued recently on DevLabs tackles that problem using model-based testing techniques.

Spec Explorer models the behaviour of application code and using the output to produce functional testing steps from those models. These models can be seen graphically to understand application behavior. These test suites can run standalone or in the Visual Studio or other unit test frameworks. A modelling background is not required before users can build models with Spec Explorer.

Models are written in C# and accompanied by configuration files in a scripting language called Cord.

From Windows 7 Performance:

Vista isn’t well-known for its performance.

One of Microsofts goals with Windows 7 was to increase performance. Observers have stated that Windows 7 seems to be much quicker than Vista. PC World Test Center carried out an evaluation which compared the two operating systems. They found an improvement in speed, though overall the improvement wasn’t dramatic.

Windows 7 has significantly improved performance, but according to PC World, Windows 7 is only slightly faster.

Windows 7 was installed on five computers (two desktops, two laptop PCs, and a netbook), and WorldBench 6 benchmark suite was installed which consists of a number of tests that measure a machine’s performance in well-liked, real world applications. Timings were collected for Windows 7 & Vista for boot-up and shutdown, laptop battery life, and launch times for several everyday apps.

Windows 7 makes some performance strides over Vista, though this was not always sizeable, and for one test, Windows 7 was beaten into 2nd by Vista.

The performance increase of Windows & over Vista is slight, the important thing is though, that there is an improvement at all.

From Computer Weekly:

So What exactly is the method of Crowdsourcing?
Testing on mass is generally done in-house by organisations. Crowdsourcing is doing the same thing but classically it is done over the internet using a lot more people.A really interesting contest recently took place that exploited Crowdsourcing. The idea was to get as many people as possible to uncover as many flaws as possible within the major search engines.- What a immense idea! A titanic battle between the search engines under test took place. It was organised by uTest. The company used crowdsourcing to put some of the worlds biggest systems under test. Apparently the turn out was unbelievable with over 50 countries participating. This included approximately 1500 resolute!
