This library contains a set of classes that performs a various set of operation in java programming language. This operation includes searching and sorting algorithms used with arrays and a cache management system that is designed to be simple and easy to use

LiNNS is not just a Neural Network Simulator, but a Neural Network System - a framework which covers the full lifecycle of a neural network, from design and research till usage in an external application.

Use own (user) data section for each Linked-List-Element (LLEl) including a fix Identifier which is for search via basic Lnkdlst function (fast ID-part-search, e.g. to find all elements with a specific bit in the ID set). Main list-linkage-change functions: append, insert, delete. - Examples: use of flexible variable ArgList (OnePointerArg, optional valid if not NULL, Argument-Type by ID-Number is easy to get), key-value pairs, build FIFO{queue}/LIFO{stack}, auto-list with max. Element-Size and chronological order. Use malloc{slower-but-easy} or fix (static) memory. - OAList01: Object-Kind of a predefined pre-reserved List with X Elements (with constant user-data size), with secur modify functions and option to use locks (POSIX: mutex). Supporting a BusyList and a IdleList for easy build of e.g. a FIFO without need of much time for mem-allocation. - Release-Notes see uws-Lnkdlst-readme.txt in the tar.gz file(s) and in „Files“.

A set of advanced Log4J appenders designed for hi-load applications. Among them: TimeAndSizeRollingFileAppender, ThreadSafeAsyncAppender, DbcpDataSourceAppender, JndiDataSourceAppender etc. Also includes appender wrappers for use in JBoss environment

Logahawk is a Java library designed to make logging easier. Logahawk aims to compliment and extend an existing logging framework, not replace it.

Lucene index tools. RCP application.

Java implementation of MIKEY (Multimedia Internet KEYing, RFC 3830).

MUG is a component-based Java Web Framework. Lightweighted and conceived to be easy to use yet flexible, it provides the developer a set of components that allows object-oriented development in a web (in the line of SWT / Swing).

Mahatma68k is a free/Open Source emulator library for the legendary Motorola 68000 CPU written for the Java virtual machine.

Give your addresses a face. MapFace is a set of JSF Facelets components for integrating the Google Maps API into any JSF application.

Material Components for Android delivers Material Design’s popular and reliable design and development resources to Android developers. With Material Design’s modular and customizable UI components, Android developers can create beautiful, high quality products faster and easier. Developed by a core team of engineers and UX designers at Google, Material Components enable developers to achieve a more reliable development workflow for building exceptional and highly functional apps. Material Components for Android is a drop-in replacement for Android's Design Support Library, offering tried and trusted Material Design guidelines and components.

If you want use this library, you only have to download MaterialDesign project, import it into your workspace and add the project as a library in your android project settings. If you are going to use a ScrollView, it is recommended that you use the CustomScrollView provided in this library to avoid problems with the custom components. You can set the accept and cancel button on the event listener or change its text. Some components have custom attributes, if you want use them, you must add some code lines in your xml file in the first component. It is recommended to put the Button component in the right-bottom of the screen. To use this component write the code in your xml file. If you don`t want to start this component with animation set the animate attribute to false. Put your icon in the icon attribute to set the drawable icon for this component.

MaterialLibrary is an open source Android library that back-port Material Design components to pre-Lolipop Android. MaterialLibrary's original author is Rey Pham. Now you can use any widget in com.rey.material.widget package as you wish. For styling, please view Wiki. Note that default style of widgets depend on theme of AppCompat. AppCompat and CardView library is required by Material library. Make sure to add the snapshot repository. You can try the SNAPSHOT version.

Java Maths library, providing several mathematical functionalities. It is intended to be a project for learning Java, Maths and project related working. This project was started in Course TAI08B1 at www.ba-karlsruhe.de

The aim of our project is to create a set of examples of use of JSF 2.1 MC Faces components from MC Components series. MC Components library provides a rich set of JSF 2.1 components with jsp and facelets support. Components available in this rich set provide simple and convenient access to funcionalities desired in each JSF web application. Most of components use famous JQuery javascript library as a javascript engine.

High performance message passing library for multi-threaded and highly concurrent Java applications, where some nodes within the cloud are untrusted. Intended for use in a distributed virtual worlds project, but probably has other interesting uses.

An open source java 5 API for parsing and obtaining queue metrics from Asterisk PBX log files.

J2ME MVC framework based on model-view-controller pattern supported ME configurations CLDC and up. - conversation like data transfer between controllers - low memory usage - PL services support TODO: - support of other UI frameworks

MicroWSS is a lightweight web services server/toolkit written in Java. Its purpose it to allow for simple development and deployment of services that use SOAP 1.2 and WSDL. It handles everything relating to XML, so that you only need to deal with Java.

Micrometer provides a simple facade over the instrumentation clients for the most popular observability systems, allowing you to instrument your JVM-based application code without vendor lock-in. Think SLF4J, but for observability. Micrometer provides vendor-neutral interfaces for timers, gauges, counters, distribution summaries, and long task timers with a dimensional data model that, when paired with a dimensional monitoring system, allows for efficient access to a particular named metric with the ability to drill down across its dimensions. Out-of-the-box instrumentation of caches, the class loader, garbage collection, processor utilization, thread pools, and more tailored to actionable insight. Micrometer is the instrumentation library powering the delivery of application observability from Spring Boot applications.

Micronaut Data is a database access toolkit that uses Ahead of Time (AoT) compilation to pre-compute queries for repository interfaces that are then executed by a thin, lightweight runtime layer. Both GORM and Spring Data maintain a runtime meta-model that uses reflection to model relationships between entities. This model consumes significant memory and memory requirements grow as your application size grows. The problem is worse when combined with Hibernate which maintains its own meta-model as you end up with duplicate meta-models. Micronaut Data instead moves this model into the compiler. Both GORM and Spring Data use regular expressions and pattern matching in combination with runtime generated proxies to translate a method definition on a Java interface into a query at runtime. No such runtime translation exists in Micronaut Data and this work is carried out by the Micronaut compiler at compilation time.
