Qigsaw
Dynamic modularization library which is based on Android App Bundles
Qigsaw is a dynamic modularization library which is based on Android App Bundles. It supports dynamic delivery for split APK without reinstalling the base one. Qigsaw-gradle-plugin will upload split APKs which require dynamic delivery during compilation, so you have to implement SplitApkUploader to upload split APKs to your own CND server. -

Quasar
Fibers, channels and actors for the JVM
Quasar is a library that provides high-performance lightweight threads, Go-like channels, Erlang-like actors, and other asynchronous programming tools for Java and Kotlin. Quasar is developed by Parallel Universe and released as free software, dual-licensed under the Eclipse Public License and the GNU Lesser General Public License. Quasar fibers rely on bytecode instrumentation. This can be done at classloading time via a Java Agent, or at compilation time with an Ant task. Quasar’s lightweight thread implementation relies on bytecode instrumentation. Instrumentation can be performed at compilation time or at runtime using a Java agent. The easy and preferable way to instrument programs using Quasar is with the Java agent, which instruments code at runtime. Sometimes, however, running a Java agent is not an option. Quasar supports AOT instrumentation with an Ant task. -

QuickSlide
A tool to generate HTML-based slide shows.
This tool allow the generation of slide shows in HTML format (to run simply in the browser). It can not replace Microsoft Power Point, but, it allows you to create a slide show by writing Java code. The generated slide show can be run easily in the browser so it is platform independent and does not need any additional software installation, even on new installed OS or Smart phones. In this first pre-alpha version, the generated code supports simple text and basic lists only, but, I hope to add more features in the future. -

QuickWeb
This tool can be used to create quickly the skeleton of a web site.
QuickWeb is a tool to quickly create a skeleton of a web site. The tool developed in Java and to create a web site, there's no need to manipulate HTML in the beginning. All you have to do is to write a simple Java code that will generate a web site of several pages. Created to help me with documenting different Sourceforge project, QuickWeb does not generate, for now, any CSS or JS code, but, it can generate the skeleton and the static content of a website composed of several web pages and ensure the navigation between them. It can, also, be used to create empty project and empty pages to avoid the annoying default HTML code. -

RE2/J
linear time regular expression matching in Java
RE2/J is a high-performance regular expression engine implemented in pure Java as a port of Google’s C++ RE2 library. Unlike traditional regex engines such as Java’s java.util.regex, PCRE, or Perl’s implementation—which rely on backtracking and can suffer from catastrophic exponential runtimes—RE2/J guarantees linear-time matching relative to input size. It achieves this efficiency by simulating all possible matches in a single pass using a nondeterministic finite automaton (NFA), ensuring predictable and safe performance even with complex patterns. This makes RE2/J ideal for applications that must handle user-supplied regular expressions securely without the risk of denial-of-service through regex backtracking. While it omits some advanced features like backreferences and certain Java regex options, it supports the vast majority of practical expressions used in production code. RE2/J thus provides a reliable, safe, and scalable alternative for developers. -

RELATED - REmotes LAboraTories extenED
Java Framework for developing of remote/virtual laboratories
RELATED framework proposes a structured methodology of remote/virtual labs development and, also, provides common facilities as user management, booking, basic visualization (trend graphs and direct interaction using interactives variables), data logging and experimental session’s control. In order to get these facilities, an RLAB (Remote LABoratory) system it defined using a formal specification of a virtual or remote laboratory (based on XML and used to structure components for laboratory). The main component is experiment, so students could run these experiments using RELATED facilities as painting data from the laboratory, change any relevant variable or take a look on laboratory structure. In order to integrate a laboratory as an RLAB system, the researchers and lecturers only have to develop local access to equipment using Java technology, using the “module” paradigm. -

RedComm
RedComm is a Java library simplifying communication with a serial port
RedComm is a lightweight Java library. It simplifies communication over the serial port by providing methods and interfaces, which can be used to read and write to the serial port or over an emulated serial cable by using bluetooth. The major focus is on the ease of use of the library. Besides that the experienced user has the ability to change the reading and writing behaviour of the library. This means the user can easily extend and customize the RedComm library. Internally RedComm uses part of the RxTx Library (http://rxtx.qbang.org/wiki/index.php/Main_Page) for port communication. Thus RedComm helps the unexperienced user using RxTx. RxTx is licensed under the LGPL 2.1 (http://www.gnu.org/licenses/old-licenses/lgpl-2.1.html). RedComm also provides facilities for event based serial communication with the help of threading in order to non-block ie. the gui thread of the corresponding application. RedComm is ideally suited for education e.g at schools. -

RegistryFilterExample
Registry Filter Driver SDK
The EaseFilter Registry Filter Driver SDK is a powerful, kernel-mode development toolkit designed to help developers monitor, control, and protect Windows registry operations in real time. It enables the development of robust security, compliance, and system integrity solutions by intercepting and managing registry access before it reaches the Windows registry subsystem. The SDK allows your application to receive notifications before any registry operation is processed by the Windows Configuration Manager. By registering a RegistryCallback routine, your application can detect: Registry key creation, deletion, renaming Registry value changes Query operations
