Delayed Write Failures

Today, I encountered this error on XP, when trying to check in and check out files from VSS database at win2k sp3.

apparently the problem fixed after following the steps described in this article.

Delayed Write Failures

Some of our customers have been experiencing difficulties with Windows "delayed write failure" errors. While this is a general class of errors that actually has many root causes, we have diagnosed one particular case that has clearly affected our customers. We have been able to replicate this problem in our lab, define the conditions under which the problem may occur, and identify some viable workarounds.

what are patterns? gamma, helm, johnson, vlissides (aka gang of four GOF) are the poineers in this area. they defined around 23 design patterns in the book, but there are many more... we started seeing patterns in architecture, model, documentations..

GOF organizes design patterns as:
1) creational patterns - patterns for dynamically selecting the class of created objects
comprising: abstractfactory,builder, factorymethod, monostate, prototype, singleton
2) structural patterns - patterns that use various language mechanisms for structuring code and assembling objects.
comprising: adapter, bridge, composite, decorator, facade, flyweight, iterator, proxy, retrofitinterface
3)Behavioral patterns - Behavioral patterns based on class tend to use inheritance to describe algorithms and flow of control, whereas the Behavioral patterns that target objects usually describe how a group of objects collaborate to perform some task that no single object can perform alone.

i will try to explain the design patterns that I have used...

1) adaptor
2) facade
3) singleton
4) factory
