Windows 8 supports all the traditional Windows applications that have been developed over past decades. But the centerpiece of Windows 8 is not its support for legacy applications. With Windows 8, Microsoft wants to develop a whole new ecosystem of applications: touch-friendly, secure, fluidly animated. The new aesthetic was known as Metro, though rumored legal issues have chased the company away from that particular name. These new applications aren't built with the time-honored Windows APIs of yore. They're built with something new: the "Windows Runtime," aka "WinRT."

- Be prepared before you have (or notice) a problem
- Then, identify and understand the crux of your problem
- Finally, fix what matters
In mid-September, the 3.6 kernel appeared to be stabilizing nicely. Most of the known regressions had been fixed, the patch volume was dropping, and Linus was relatively happy. Then Nikolay Ulyanitsky showed up with a problem: the pgbench PostgreSQL benchmark ran 20% slower than under 3.5. The resulting discussion shows just how hard scalability can be on contemporary hardware and how hard scheduling can be in general.

As you may have read by now, it's a good idea to avoid identity-style identifier strategies with ORM's. One of the better alternatives that i kinda like is the guid.comb strategy. Using regular guids as a primary key value leads to fragmented indexes (due to the randomness of the guid's value) which leads to bad performance. This is a problem that the guid.comb strategy can solve quite easily for you.

In this article, Jimmy Nilsson presents the pros and cons of using globally unique identifiers (GUIDs) as the datatype for primary keys in SQL Server 2000. In doing so, he shows you test results that hint of performance characteristics and introduces you to a special type of GUID that he invented, called COMBs, that solves what otherwise might give you a big throughput problem.
