Linux has finally come of age and is now a legitimate gaming platform. The release of quality commercial titles such as Left 4 Dead 2, Portal, and Day of Defeat bring real credibility to Linux as a first-class gaming platform. The bid to lure gamers away from Microsoft's platform has also been strengthened, in part, due to the official launch of Steam for the Linux operating system back on February 14.

Technology tools do have their limits. No one will become a master chef simply because they use chef-endorsed saucepans, the finest ingredients, or have access to sought-after recipes. For example, a diary application can make it easier for individuals to keep track of their daily activities and thoughts, but will the application really bring order into a chaotic world? Time tracker apps help users keep track of how much time is spent on various activities during the day, but still the user has to remember to start them.

Scheme is a general-purpose, functional, programming language that is descended from Lisp and Algol. It is a statically scoped and properly tail-recursive dialect of Lisp.

Scala is a modern, object-functional, multi-paradigm, Java-based programming and scripting language that is released under the BSD license. It blends the functional and object-oriented programming models.

The use of paper has been displaced from some activities. For example, the vast majority of journeys on the London Underground are made using the Oyster card without a paper ticket being issued. We have witnessed talk of a paperless office for more than 40 years. However, the office environment has shown a resistance to remove the mountain of paper generated. Things have changed in the past few years, with a marked shift in the paperless office concept.

Oceans of data are now not only found in large companies; even some small companies accumulate terabytes of data. Organisations of all sizes therefore have an increased need to handle large amounts of data, and relational databases are stretched to their limits in terms of scalability. Where Big Data is concerned, we need a platform that is scalable and optimized for storing, managing, and querying unstructured data.

Key value stores allow the application to store its data in a schema-less way. The data can be stored in a datatype of a programming language or an object.

Oceans of digital data are being created from the interaction between individuals, businesses, and government agencies. There are enormous benefits open to organisations providing they effectively identify, access, filter, analyze and select parts of this data.
