Apache Commons Lang


Claimed by Apache Software Foundation Analyzed about 3 hours ago

Provides extra functionality for classes in java.lang. Lang provides a host of helper utilities for the java.lang API, notably String manipulation methods, basic numerical methods, object reflection, concurrency, creation and serialization and System properties. Additionally it contains basic ... [More] enhancements to java.util.Date and a series of utilities dedicated to help with building methods, such as hashCode, toString and equals. [Less]

Akka is the platform for the next generation event-driven, scalable and fault-tolerant architectures on the JVM We believe that writing correct concurrent, fault-tolerant and scalable applications is too hard. Most of the time it's because we are using the wrong tools and the wrong level of ... [More] abstraction. Akka is here to change that. Using the Actor Model together with Software Transactional Memory we raise the abstraction level and provides a better platform to build correct concurrent and scalable applications. For fault-tolerance we adopt the "Let it crash" / "Embrace failure" model which have been used with great success in the telecom industry to build applications that self-heals, systems that never stop.

Inferno Distributed Operating System


  Analyzed 3 months ago

Inferno® is a distributed operating system, originally developed at Bell Labs, but now developed and maintained by Vita Nuova® as Free Software. Applications written in Inferno's concurrent programming language, Limbo, are compiled to its portable virtual machine code (Dis), to run anywhere on a ... [More] network in the portable environment that Inferno provides. Unusually, that environment looks and acts like a complete operating system. The use of a high-level language and virtual machine is sensible but mundane. The interesting thing is the system's representation of services and resources. They are represented in a file-like name hiearchy. Programs access them using only the file operations open, read/write, and close. The 'files' may of course represent stored data, but may also be devices, network and protocol interfaces, dynamic data sources, and services. The approach unifies and provides basic naming, structuring, and access control mechanisms for all system resources. A single file-service protocol (called Styx or 9P2000) makes all those resources available for import or export throughout the network in a uniform way, independent of location. An application simply attaches the resources it needs to its own per-process name hierarchy ('name space'). The system can be used to build portable client and server applications. It makes it straightforward to build lean applications that share all manner of resources over a network, without the cruft of much of the 'Grid' software one sees. Inferno can run 'native' on various ARM, PowerPC, SPARC and x86 platforms but also 'hosted', under an existing operating system (including FreeBSD, Irix, Linux, MacOS X, Plan 9, and Solaris), again on various processor types.

Hundreds of functions of a variety of topics, from statistics to string parsing, module utilities to network tools. Everyone's pet library accumulates features over time. My erlang library got big, fast. I often find myself giving functions from it out to other people, and a lot of my other ... [More] libraries are dependant on ScUtil in various ways, so I figured what the hell, let's give it away. This library is believed to be efficiently implemented at all points. Efficiency tips are, however, both appreciated and taken seriously. ScUtil uses the TestErl library for unit, regression and stochastic testing. ScUtil is free and MIT licensed, because the GPL is evil. ScUtil is written by John Haugeland, from http://fullof.bs/ . [Less]
