"Ning-compress is a Java library for encoding and decoding data in LZF format, compatible with standard C LZF package."

"Snappy is a compression/decompression library. It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression. For instance, compared to the fastest mode of zlib, Snappy is an order of magnitude faster for most inputs, but the resulting compressed files are anywhere from 20% to 100% bigger. On a single core of a Core i7 processor in 64-bit mode, Snappy compresses at about 250 MB/sec or more and decompresses at about 500 MB/sec or more. Snappy is widely used inside Google, in everything from BigTable and MapReduce to our internal RPC systems. (Snappy has previously been referred to as "Zippy" in some presentations and the likes.)"

"Shark is a large-scale data warehouse system for Spark designed to be compatible with Apache Hive. It can execute Hive QL queries up to 100 times faster than Hive without any modification to the existing data or queries. Shark supports Hive's query language, metastore, serialization formats, and user-defined functions, providing seamless integration with existing Hive deployments and a familiar, more powerful option for new ones."

"Apache Hama is a pure BSP (Bulk Synchronous Parallel) computing framework on top of HDFS (Hadoop Distributed File System) for massive scientific computations such as matrix, graph and network algorithms. Today, many practical data processing applications require a more flexible programming abstraction model that is compatible to run on highly scalable and massive data systems (e.g., HDFS, HBase, etc). A message passing paradigm beyond Map-Reduce framework would increase its flexibility in its communication capability. Bulk Synchronous Parallel (BSP) model fills the bill appropriately. Some of its significant advantages over MapReduce and MPI are: * Supports message passing paradigm style of application development * Provides a flexible, simple, and easy-to-use small APIs * Enables to perform better than MPI for communication-intensive applications * Guarantees impossibility of deadlocks or collisions in the communication mechanisms"

"Protostuff is the stuff that leverages google's protobuf. A serialization library with built-in support for forward-backward compatibility (schema evolution) and validation. available formats: protostuff (native) graph (protostuff with support for cyclic references. See SerializingObjectGraphs) protobuf json smile (binary json useable from the protostuff-json module) xml yaml (ser only) kvp (binary uwsgi header) support for messages that are generated by the protostuff-compiler (java_bean) cyclic references via graph format see CompilerOptions for more customized compilation of .proto files support for existing pojos (See runtime schemas) cyclic references via graph format polymorphic (a nested message can be an interface/abstract class or even java.lang.Object) support for existing protoc-generated java messages see the io instructions for json, xml, yaml) no support for cyclic references (limitation of the builder pattern) Interoperability across various mobile platforms android kindle j2me (protostuff-me module) Transcoding support converts one encoding to another. See PipeUsage. Source and Sink protostuff, protobuf, json, json-numeric, smile, smile-numeric, xml Sink only yaml "

"The Mono Migration Analyzer (MoMA) tool helps you identify issues you may have when porting your .Net application to Mono. While Mono aims to be binary compatible with .Net, MoMA helps pinpoint platform specific calls (P/Invoke) and areas that are not yet supported by the Mono project."

La versión actual de MoMA solamente analiza compatibilidad contra Mono 2.8 (circa 2010).

"Shark is a large-scale data warehouse system for Spark designed to be compatible with Apache Hive. It can answer Hive QL queries up to 100 times faster than Hive without modification to the existing data nor queries. Shark supports Hive's query language, metastore, serialization formats, and user-defined functions."

Consumers Pacto helps you test consumers by both validating and stubbing services. This helps you decouple tests to reduce test times and non-deterministic test failures without losing confidence in your test suite. You can also design compatibility tests for similar consumers. Providers You can use Consumer-Driven Contracts to ensure you're providers are well tested without losing agility. Pacto will test the provider implementation and make sure it complies with the same contract used to stub the service for consumers.

Este se ve mejor. "Package grace provides a library that makes it easy to build socket based servers that can be gracefully terminated & restarted (that is, without dropping any connections). It provides a convenient API for HTTP servers including support for TLS, especially if you need to listen on multiple ports (for example a secondary internal only admin server). Additionally it is implemented using the same API as systemd providing socket activation compatibility to also provide lazy activation of the server."
