+Thrift is a serialization and RPC framework for service communication. Thrift enables these features in all major languages, and there is strong support for C++, Python, Hack, and Java. Most services at Facebook are written using Thrift for RPC, and some storage systems use Thrift for serializing records on disk.
+
+Facebook Thrift is not a distribution of Apache Thrift. This is an evolved internal branch of Thrift that Facebook re-released to open source community in February 2014. Facebook Thrift was originally released closely tracking Apache Thrift but is now evolving in new directions. In particular, the compiler was rewritten from scratch and the new implementation features a fully asynchronous Thrift server. Read more about these improvements in the ThriftServer documentation.
+
+You can also learn more about this project in the original Facebook Code blog post.

+The core protocol implementations are in ClientProtocol and ServerProtocol. FizzClientContext and FizzServerContext provide configuration options. FizzClient and FizzServer (which both inherit from FizzBase) provide applications with an interface to interact with the state machine. FizzClient/FizzServer receives events from the application layer, invokes the correct event handler, and invokes the application ActionVisitor to process the actions.
+
+AsyncFizzClient and AsyncFizzServer provide implementations of the folly AsyncTransportWrapper interface. They own an underlying transport (for example AsyncSocket) and perform the TLS handshake and encrypt/decrypt application data.

+  <longdescription>
+    The evaluation of a mathematical expression is a standard task required in many applications. It can be solved by either using a standard math expression parser such as muparser or by embedding a scripting language such as Lua. There are however some limitations: Although muparser is pretty fast it will only work with scalar values and although Lua is very flexible it does neither support binary operators for arrays nor complex numbers. So if you need a math expression parser with support for arrays, matrices and strings muparserx may be able to help you.

+Overview
+
+This repository aims to provide a set of excellent hash map implementations, as well as a btree alternative to std::map and std::set, with the following characteristics:
+
+Header only: nothing to build, just copy the parallel_hashmap directory to your project and you are good to go.
+
+drop-in replacement for std::unordered_map, std::unordered_set, std::map and std::set
+
+Compiler with C++11 support required, C++14 and C++17 APIs are provided (such as try_emplace)
+
+Very efficient, significantly faster than your compiler's unordered map/set or Boost's, or than sparsepp
+
+Memory friendly: low memory usage, although a little higher than sparsepp
+
+Supports heterogeneous lookup
+
+Easy to forward declare: just include phmap_fwd_decl.h in your header files to forward declare Parallel Hashmap containers [note: this does not work currently for hash maps with pointer keys]
+
+Dump/load feature: when a flat hash map stores data that is std::trivially_copyable, the table can be dumped to disk and restored as a single array, very efficiently, and without requiring any hash computation. This is typically about 10 times faster than doing element-wise serialization to disk, but it will use 10% to 60% extra disk space. See examples/serialize.cc. (flat hash map/set only)
+
+Automatic support for boost's hash_value() method for providing the hash function (see examples/hash_value.h). Also default hash support for std::pair and std::tuple.
+
+natvis visualization support in Visual Studio (hash map/set only)

+Features
+
+Reasonably fast, without GPU:
+With TBB threading and SSE/AVX vectorization.
+98.8% accuracy on MNIST in 13 minutes training (@Core i7-3520M).
+Portable and header-only:
+Runs anywhere as long as you have a compiler which supports C++14.
+Just include tiny_dnn.h and write your model in C++. There is nothing to install.
+Easy to integrate with real applications:
+No output to stdout/stderr.
+A constant throughput (simple parallelization model, no garbage collection).
+Works without throwing an exception.
+Can import caffe's model.
+Simply implemented:
+A good library for learning neural networks.
+
+Supported networks

+Client / Server abstraction
+
+You're probably familiar with Java's Netty, or Python's twisted, or similar libraries.
+
+It is built on top of folly/async/io, so it's one level up the stack from that (or similar abstractions like boost::asio)
+
+ServerBootstrap - easily manage creation of threadpools and pipelines
+
+ClientBootstrap - the same for clients
+
+Pipeline - set up a series of handlers that modify your socket data
+
+Request / Response abstraction
+
+This is roughly equivalent to the Finagle library.
+
+Aims to provide easy testing, load balancing, client pooling, retry logic, etc. for any request/response type service - i.e. thrift, http, etc.
+
+Service - a matched interface between client/server. A server will implement this interface, and a client will call in to it. These are protocol-specific
+
+ServiceFilter - a generic filter on a service. Examples: stats, request timeouts, rate limiting
+
+ServiceFactory - A factory that creates client connections. Any protocol specific setup code goes here
+
+ServiceFactoryFilter - Generic filters that control how connections are created. Client examples: load balancing, pooling, idle timeouts, markdowns, etc.
+
+ServerBootstrap
+
+Easily create a new server
+
+ServerBootstrap does the work to set up one or multiple acceptor threads, and one or multiple sets of IO threads. The thread pools can be the same. SO_REUSEPORT is automatically supported for multiple accept threads. tcp is most common, although udp is also supported.
