Google File System (GFS or GoogleFS, not to be confused with the GFS Linux file system) is a proprietary distributed file system developed by Google to provide efficient, reliable access to data using large clusters of commodity hardware. Google file system was replaced by Colossus in 2010.
There is a FUSE module so that the file system can be mounted on Linux. In September 2007, Kosmix published Kosmosfs as open source. [1] The last commit activity was in 2010. The Google Code page for Kosmosfs now points to the Quantcast File System on GitHub which is the successor to KFS. [2] A former project on SourceForge used the name ...
Source Code Control System (SCCS) [open, shared] – part of UNIX; based on interleaved deltas, can construct versions as arbitrary sets of revisions; extracting an arbitrary version takes essentially the same time and is thus more useful in environments that rely heavily on branching and merging with multiple "current" and identical versions
Qalculate! supports common mathematical functions and operations, multiple bases, autocompletion, complex numbers, infinite numbers, arrays and matrices, variables, mathematical and physical constants, user-defined functions, symbolic derivation and integration, solving of equations involving unknowns, uncertainty propagation using interval arithmetic, plotting using Gnuplot, unit and currency ...
Google has acknowledged that Python has played an important role from the beginning, and that it continues to do so as the system grows and evolves. [116] The software that runs the Google infrastructure includes: [117] Google Web Server (GWS) – custom Linux-based Web server that Google uses for its online services. Storage systems:
Bazel is extensible with the Starlark programming language. [13] Starlark is an embedded language whose syntax is a subset of the Python syntax. However, it doesn't implement many of Python's language features, such as the ability to access the file I/O, in order to avoid extensions that could create side-effects or create build outputs not known to the build system itself.
Much of this code is user-created freeware or even open source, though commercial software, particularly for educational and science/engineering markets, is also available. Programmable calculators have major websites with information, documentation, message boards, tools for download, and other things useful for this pursuit; the main sites ...
Google I/O is Google's largest developer event, which is usually held in May at the Shoreline Amphitheatre, Mountain View. Google Summer of Code is a mentoring program to find students for open source projects. In 2016, the program received nearly 18,980 applications. Google Code Jam is an international programming competition.
