The libraries are aimed at a wide range of C++ users and application domains. They range from general-purpose libraries like the smart pointer library, to operating system abstractions like Boost FileSystem, to libraries primarily aimed at other library developers and advanced C++ users, like the template metaprogramming (MPL) and domain-specific language (DSL) creation (Proto).
A version 1.1 "pre-release" was released in October 2008. The second major release of the OpenCV was in October 2009. OpenCV 2 includes major changes to the C++ interface, aiming at easier, more type-safe patterns, new functions, and better implementations for existing ones in terms of performance (especially on multi-core systems).
Pip's command-line interface allows the install of Python software packages by issuing a command: pip install some-package-name. Users can also remove the package by issuing a command: pip uninstall some-package-name. pip has a feature to manage full lists of packages and corresponding version numbers, possible through a "requirements" file.

Word2vec is a technique in natural language processing (NLP) for obtaining vector representations of words. These vectors capture information about the meaning of the word based on the surrounding words.
For #include guards to work properly, each guard must test and conditionally set a different preprocessor macro. Therefore, a project using #include guards must work out a coherent naming scheme for its include guards, and make sure its scheme doesn't conflict with that of any third-party headers it uses, or with the names of any globally visible macros.
Its price was ¥298,000 MSRP, equal to about $1,200 (at $1 = ¥250), and $1,200 in 1980 had the approximate buying power of $3,000 in 2007. An early consumer implementation of picture-in-picture was the Multivision set-top box; it was not a commercial success. Later, PiP became available as a feature of advanced television receivers.
The 2CV sold poorly in Great Britain in part due to its excessive cost, because of import duties on components. In 1959, the British Royal Navy ordered 65 2CV pick-ups from the Slough plant, following sea tests aboard HMS Bulwark in the West Indies and the Indian Ocean during 1957–58, with the Westland Whirlwind helicopters of 845 squadron RNAS.
