Introduction
Design Patterns are well known design solutions for well known design problems. Design pattern will provide you the approach in which you have to solve the design and not the implementation. Design patterns will not define the architecture, but only defines the solutions for the design problems.
A Famous architect called Christopher Alexander originated the concept. Later the concept was copied to other disciplines. Gang-of-four is a well know book on software design patterns.
Patterns are something which are recurring. If we take some design problems we will be able to correlate some common patterns in it. Design patterns help you in resolving those issues which has already proven solutions developed.
Types
There are four types of design patterns.
1) Creational Pattern - Deals with how the object needs to be created.
2) Structural Pattern - Deals with how to establish relation between two entities.
3) Behavioral Pattern - Deals with the common communication patterns between the objects.
4) Concurrency Pattern - Quiz? Can somebody answer?

Issues reported during the suspend-to-disk process lead Linux creator Linus Torvalds to suggest, "please - just make the f*cking suspend-to-disk use other routines already. 99% of all hardware needs to do exactly *nothing* on suspend-to-disk, and the ones that really do need things tend to need to not do a whole lot."

This paper is a tutorial on floating-point arithmetic and describes of three loosely connected parts. The first section, Rounding Error, discusses the implications of using different rounding strategies for the basic operations of addition, subtraction, multiplication and division. It also contains background information on the two methods of measuring rounding error, ulps and relative error. The second part discusses the IEEE floating-point standard, which is becoming rapidly accepted by commercial hardware manufacturers. Included in the IEEE standard is the rounding method for basic operations. The discussion of the standard draws on the material in the section Rounding Error. The third part discusses the connections between floating-point and the design of various aspects of computer systems. Topics include instruction set design, optimizing compilers and exception handling.

Specifically, in Microsoft® Windows Server® Code Name "Longhorn" and Windows Vista™ you can apply computer policy to:• Prevent users from installing any device.• Allow users to install only devices that are on an "approved" list. If a device is not on the list, then the user cannot install it.• Prevent users from installing devices that are on a "prohibited" list. If a device is not on the list, then the user can install it.• Deny read or write access to users for devices that are themselves removable, or that use removable media, such as CD and DVD burners, floppy disk drives, external hard drives, and portable devices such as media players, smart phones, or Pocket PC devices.Step-By-Step Guide to Controlling Device Installation and Usage with Group Policy

"In bacteria (and viruses), duplication of DNA/RNA is a big cost of living in general, and as a result there is *much* less junk DNA. So in an evolutionary sense, it's much closer to what the kernel should have (with occasional duplication of code and interfaces to allow new functionality, but rather aggressive pruning of the excess baggage). In other words, all of these choices are a matter of 'balance'. In some areas, excess code is not a sufficient downside, and we keep even broken source code around with no actual function, 'just because' (or rather, because the cost of carrying it around is so small that nobody cares)."Kernel Evolution | KernelTrap

"As you probably know there is a trend in enterprise computing towards networked storage. This is illustrated by the emergence during the past few years of standards like SRP (SCSI RDMA Protocol), iSCSI (Internet SCSI) and iSER (iSCSI Extensions for RDMA)," began Bart Van Assche, proposing that SCST be merged into the mainline kernel. He suggested that while similar to the STGT project which has been part of the mainline kernel since 2.6.20, "SCST is superior to STGT with respect to features, performance, maturity, stability, and number of existing target drivers. Unfortunately the SCST kernel code lives outside the kernel tree, which makes SCST harder to use than STGT."
