Vapi

Vapi (IAST: vāpī, pronunciation ), is a city and municipality in Valsad District in the state of Gujarat. It is situated on the banks of the Damanganga River and is the largest city in the Valsad district and also the second largest city after Surat in South Gujarat.It can be called the most developed city in Gujarat followed by Ahemdabad, Surat, Vadodara and Rajkot.

Around 28 km south of the district headquarters in the city of Valsad, it is surrounded by the Union Territories of Daman to the west and Dadra and Nagar Haveli to the east. Economic and industrial growth in recent decades has blurred the physical boundaries, and a small stretch of roughly 21 km of Daman-Vapi-Silvassa has almost become a single urban area. The town originally belonged to the community of Desai (Anavil Bramhins), Jain and other tribal castes. It is the largest industrial area in Asia in terms of small-scale industries, dominated by the chemical industry. It has been ranked 2 in the year 2008 among the most polluted places in the world, mainly due to its poor air and water quality caused by nearby industrial sites.

Vala (programming language)

Vala is an object-oriented programming language with a self-hosting compiler that generates C code and uses the GObject system (that "can be seen as an alternative to C-derived languages such as C++ and Objective-C").

Vala is syntactically similar to C# and includes several features such as: anonymous functions, signals, properties, generics, assisted memory management, exception handling, type inference, and foreach statements. Its developers Jürg Billeter and Raffaele Sandrini aim to bring these features to the plain C runtime with little overhead and no special runtime support by targeting the GObject object system. Rather than compiling directly to machine code or assembly language, it compiles to a higher level intermediate language. It source-to-source compiles to C, which is then compiled with a C compiler for a given platform, such as GCC.

For memory management, the GObject system provides reference counting. In C, a programmer must manually manage adding and removing references, but in Vala, managing such reference counts is automated if a programmer uses the language's built-in reference types rather than plain pointers.
