Nagios is (in my opinion) one of the finest availability and monitoring solutions available. The stability, extendability and cost effectiveness (it is free under the GPL), are second to none (again, my opinion). That being said, it is far from being the easiest monitoring solution to implement. The build process itself, while not being overly complicated, can be vexing to new Linux users. That doesn't even include the configuration, which sometimes still makes me cringe.

RDMA - Remote DMA - extends DMA concept to networking. Networking tends to involve a lot of data copying, and a lot of work by the operating system. Many network cards support DMA already, but this only allows a DMA transfer of raw network data from the card into the OS Kernel’s memory. This data must be decoded as it moves through the protocol stack, which typically involves additional copying, and eventually it is deliver to a user space program (which involves yet another copy). All this copying is particularly necessary since the kernel must virtualize the shared network interface to all the programs running on a system. The kernel needs to ensure that a user program cannot read network traffic meant for a different program. As network interfaces keep getting faster this overhead becomes more and more significant. Special network interface cards implement the protocol stack in silicon on the card.

Devices like hard disks, serial ports, and parallel ports have an internal Windows NT device name and may optionally have an MS-DOS device name. These names are located in the Windows NT Object Manager's namespace. While Windows NT itself and kernel-mode drivers use NT device names, Win32 programs must use the MS-DOS device names. The MS-DOS device name is a symbolic link to the underlying NT device name. This article describes device names, symbolic links, and how Win32 programs can create and remove symbolic links.

Linear Hashing is a dynamic hash table algorithm invented by Witold Litwin (1980) , and later popularized by Paul Larson. Linear hashing allows for the expansion of the hash table one slot at a time. The frequent single slot expansion can very effectively control the length of the collision chain. The cost of hash table expansion is spread out across each hash table insertion operation, as opposed to be incurred all at once.  Therefore linear hashing is well suited for interactive applications.

I faced a situation recently while building a Web application where a Web service that we made requests from would occasionally hang when we made a request. Because we run our application on Linux, we decided to use signals to add a timeout to our request. Because we use Python, we implemented the timeout as a decorator, since we knew we would likely find other places where we needed to add timeouts. A simplified version of this code makes an excellent introduction to how decorators work.

With the inherent support for SMP and preemptive scheduling in Linux, concurrency is a critical factor which has to be considered while designing kernel modules or device drivers.

Almost all modern computer system hardware allows its power usage to be managed and its temperature to be monitored and kept at the appropriate level. This allows users to achieve the best performance from a system for a given level of power usage. This is especially important for battery-driven mobile platforms where unnecessary use of power reduces battery life and thus reduces the amount of work that can be done before a recharge is necessary. It is also useful in desktop environments where devices such as computer monitors and disk drives can be powered down during idle times to reduce energy consumption.
