    eBus

    Publish/Subscribe, Request/Reply Messaging API for Java.

    A Java middleware API supporting broker-less, type+topic-based publish/subscribe and request/reply messaging for both intra- and inter-application, object-level communication. Broker-less: messages are transmitted directly between eBus applications. There is no message broker (i.e. server) in between. Type+topic addressing: eBus clients subscribe to a message class (type) and message topic, providing stronger typing than just topic-based subscriptions. Object-level communication: eBus delivers messages directly to client objects, not to a client process.

    A-JLib

    A simple java lib with Swing widgets and other stuff.

    A simple java library with Swing widgets and other stuff. This library tries to simplify the development of Swing applications ... which is sometime a nightmare ! It contains the classes I developed during the Yapbam project in order to deal with the problems I encountered. This work is still under progress and some things may be changed in the future (especially some class names). The classes available here are quite stable and used in the Yapbam project. AJlib is also available through Maven GroupId: com.fathzer ArtifactId: ajlib javadoc is at https://javadoc.io/doc/com.fathzer/ajlib

    Super CSV

    A fast, programmer-friendly, free CSV library for Java

    Super CSV is a fast, programmer-friendly, open-source library for reading and writing CSV files with Java. PLEASE NOTE: As of January 2015 we have now moved to GitHub (https://github.com/super-csv/super-csv). This SourceForge page will remain, but with limited functionality (please go to GitHub to report issues and for project downloads). It is highly configurable, and supports reading and writing with POJOs, Maps and Lists. It also has support for deep-mapping and index-based mapping with POJOs, using the powerful Dozer extension. Its flexible 'Cell Processor' API automates data type conversions (parsing and formatting Dates, Integers, Booleans etc) and enforces constraints (mandatory columns, matching against regular expressions etc) - and it's easy to write your own if required. Super CSV is actively maintained, and the developers are ready and willing to help out if you get stuck :) Please check out the project website for examples and help getting started

    Java-Arduino Communication Library

    Serial Communication between Java and Arduino made simple.

    Serial Communication between Arduino and Java has never been simpler. A better alternative to the RXTX library, the JavaArduinoLibrary is an easy to use library with simple methods that allow you, the JAVA programmer, to read and write from the serial port. Seamless serial communication with the port of your choice. Consists of a class that extends the JComboBox to provide a list of all available ports for selection. Overloaded functions for serialWrite() and serialRead() allow multiple methods of communication. Overloaded constructors and getter and setter methods expand the use case to any scenario. **IMPORTANT**: please download and import both JARs in the files into your project.

    Hadoop-BAM is a Java library for the manipulation of files in common bioinformatics formats using the Hadoop MapReduce framework with the Picard SAM JDK, and command line tools similar to SAMtools. The file formats currently supported are BAM, SAM, FASTQ, FASTA, QSEQ, BCF, and VCF. For a longer high-level description of Hadoop-BAM, refer to the article "Hadoop-BAM: directly manipulating next generation sequencing data in the cloud" in Bioinformatics Volume 28 Issue 6 pp. 876-877, available online at: http://dx.doi.org/10.1093/bioinformatics/bts054 Note that the library part of Hadoop-BAM is mainly for developers with experience in using Hadoop. The command line tools of Hadoop-BAM should be understandable to all users, but they are limited in scope. See the SeqPig project for a higher-level interface to the file formats supported by Hadoop-BAM: http://seqpig.sourceforge.net See Seal for Hadoop-based read alignment tools, Seal: http://biodoop-seal.sourceforge.net
