    Thimble

    An asynchronous task execution library for Java

    Thimble is a multi-thread Executor implementation that supports sequential and coalescing tasks. Sequential tasks are guaranteed to run in order, sequentially (but may run in different threads). Coalescing tasks are tasks where only the latest submitted task needs to be executed (effectively overwriting previously submitted tasks). Sequential and coalescing tasks are mutually exclusive.

    eCxx

    eCxx

    A C++ library for AVR and NodeMCU

    NOTE: This project is marked with 'Status: Abandoned' on SourceForge because not enough time can be dedicated to this project. However it may still get sporadic commits to the repository. eCxx is a library for AVR and NodeMCU tailored for micro LED displays and lighting effects. eCxx is utilizing Makefile build system. Java and Python based applications/tools are also included to ease the development and debugging process using the host PC. On one side, eCxx supports the original megaAVR series (ATmega328P, ATmega1284P, ATmega2560, ATmega32U4, AT90USB1286, etc.) as well as the new megaAVR 0-Series (ATmega4808, ATmega4809, etc.). On the other side, while eCxx is primarily designed to work in NodeMCU, it should also support other ESP-12 based design as well as ESP-01 based design. The Makefile build system and some of the tools would only run on Linux. However, the library source code should be portable enough to be built using other build systems for AVR and NodeMC

    streamsupport

    streamsupport

    Backport of Java 8/9 java.util.stream API to Java 6/7 and Android

    This project has moved to GitHub: https://github.com/stefan-zobel/streamsupport streamsupport is a backport of the Java 8 java.util.function (functional interfaces) and java.util.stream (streams) API for users of Java 6 or 7 supplemented with selected additions from java.util.concurrent which didn't exist back in Java 6. Due to the lack of default interface methods and static interface methods in pre-Java 8 the API had to be slightly adjusted in these areas but still covers the full functionality scope of Java 8. In detail, static and default interface methods have been moved to companion classes in the same package that bear the identical name as the interface but with an "s" appended (e.g. Comparator -> Comparators). For ease of use, the default methods for most of the functional interfaces were NOT retained as abstract methods in the redefined interfaces - the missing default (and static) methods can always be found in the corresponding companion class.

    .Net Native Interface Library

    The best library to work with .Net Assemblies in any programming lang.

    The .Net Native Interface Library (DotNetNativeInterface) is a native programming interface which provides a way for programming languages such as C, C++, Fortran, Assembly, Pascal, Java, VB etc to interact with applications and libraries written in any of the .Net languages (such as C#, VB.Net etc). Programmers can use DotNetNativeInterface native methods to access .Net 3rd party libraries or .Net Framework Libraries without the need for registry entries, COM registrations or changes to the .Net libraries. The following examples illustrate when you need to use DotNetNativeInterface native methods: 1. You want to access and use .Net Framework Class Library in your application. 2. You want to access and use 3rd party .Net Libraries in your application. Competitive Advantages: 1. Access to .Net Framework Class Library. 2. No COM registration of .Net Libraries is required when deployed. 3. Allows any programming language to consume .Net libraries as if they were native code.

    30 Seconds of Java

    30 Seconds of Java

    Collection of reusable tested Java 21 compatible code snippets

    30 Seconds of Java is a curated collection of short, focused Java code snippets intended to teach small concepts quickly, similar to the popular “30 seconds of code” format in other languages. Each snippet is designed to be read and understood in under a minute, showing a single idea such as working with streams, handling optionals, manipulating collections, or doing common utility tasks. The repo targets both beginners who want bite-sized learning and experienced developers who just need a ready-made idiom without digging through docs. Because the snippets are standalone, you can copy them directly into your project or adapt them with minimal changes. The collection is organized and documented so you can browse by category and skill level. Overall, it’s a convenient library for learning modern, idiomatic Java fast and applying it right away.

    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
