How does AppFabric cache calculates the values for RequestCount, ReadRequestCount, WriteRequestCount and MissCount?

When I started to use the Get-CacheStatistics cmdlet to monitor caching activities more intensivley I was often confused. Here an example:

Should not be ReadCount+WriteCount = RequestCount? Why is WriteRequestCount increasing +2 although I just send one put request?

By talking to Microsoft support I figured out how AppFabric cache calculates its numbers (Thanks to Gayathri from Distributed Service Team). Number calculation behavior depends on your configuration, high availability and local cache have a major impact on it.

Activity	RequestCount	ReadRequestCount	WriteRequestCount	MissCount
DataCacheFactory is initialized and Named Cache is up	+1	-	-	-
Put item, not yet in local and server cache	+1	-	+1 (+2 with HA)	+1
Get item from local cache	-	-	-	-
Get item from server cache, local cache has expired	+1	+1	-	-
Get item, local and server cache has expired	+1	+1	-	+1

I hope this is helpful for you when you are analyzing the caching behavior for your application.

How to integrate AVM smart devices into HomeKit by using openHAB

Have you ever reconsidered your personal iPhone security policy?

Why should I reconsider my iPhone security policy? I have my iPhone four digit pass code and Find my iPhone feature feature is activated. So how should abuse be possible? What could a thief be doing with my stolen iPhone? Well, possibly quite a lot. At least the bold print bullets in this article should be mandatory for everyone. Of course this is no guarantee for invulnerability but it will improve your security. After watching this video you should consider the following actions: Change your Apple ID rescue mail address and do not add this mail account to your iPhone. Consider to use a proper and usable password policy for your Apple ID like this or this (German article) . Consider a complex pass code for your iPhone. As you can see in the video four digit pass codes can be hacked in no time on iPhone 4. For newer iPhone a leak is not yet known but it is properly there. Definitely do not use these pass codes . Alternative to point three: activate delete iPhone after 10 wrong...

Two annoying issues in Visual Studio regarding XSDs and WCF should be fixed immediately

In my daily work I am always stumbling on two annoying features in Visual Studio, and I think it could be improved easily. Here is what I am complaining about. WCF Test Client WCF Test Client might be a nice tiny tool for small WCF tests, especially when you are testing smaller scenarios or when you are starting to learn how to implement web services with .NET. But it can be very annoying when you are working on more advanced stuff and your are testing with your local IIS. WCF Test Client always(!) starts automatically when you press F5 for debugging and your opened .svc.cs file has the focus: When I have configured local IIS is the target for debugging, then I expect my application will start with local IIS and not with WCF Test Client. Always. Here is my first urgent request: Please give me an option to disable WCF Test Client completely! Update 03.03.2014: Workaround for WCF Test Client Issue Select project file -> Right click -> Properties -> Web -> Sele...
