    JDiskCat

    JDiskCat

    Multi-platform disk cataloguing utility written in java.

    Easy-to-use multi-platform disk cataloguing program supporting local or removable media - drives and folders. Uses XML files as a data storage. It was originally created in 2010 to catalogue software compilations (also called freeware compilations) and CDs distributed with computer magazines. It was later improved to support any kind of disk and folder. It can be used to catalogue fragile disks like CDs, floppies, external hard drives, usb sticks, memory cards which are easy to damage. Cataloguing enables user to check what they contain without putting them physically into drive and avoid a possibility of a mechanical damage. Download package consists of a jar file and a Eclipse project with a full source code. No installation is required. You can copy this program anywhere or transfer it to another computer. Setting unique volume label to a drive before cataloguing is recommended. See blog or homepage for news and changelog. This program requires JRE 8 or newer.

    AGI (Android GPU Inspector)

    AGI (Android GPU Inspector)

    Android GPU Inspector

    Android GPU Inspector (AGI) is a desktop tool for profiling, tracing, and debugging graphics workloads running on Android devices. It helps developers analyze Vulkan and OpenGL ES applications at the system, frame, and draw-call levels to uncover GPU and CPU bottlenecks. AGI captures detailed performance counters, timelines, and pipeline state to reveal stalls, overdraw, shader hotspots, and inefficient resource usage. Its frame debugger lets you step through commands, inspect render targets and textures, review shaders, and experiment with pipeline changes to validate optimizations. Beyond per-frame analysis, AGI correlates GPU activity with CPU threads and system events to diagnose contention, scheduling issues, and thermal or power constraints. The tool is designed for reproducible performance investigations, making it easier to iterate, compare captures, and ship smoother, more efficient Android graphics experiences.

    Android Volley

    Android Volley

    This is an unofficial mirror (with some minor bugfix) for volley

    Android Volley is a deprecated unofficial mirror of Google’s Volley networking library with a small number of additional bug fixes. It was packaged for convenient Gradle installation through an older Maven Central artifact. The underlying library schedules Android network requests, supports concurrent connections, and provides disk and memory response caching. It can prioritize or cancel requests and includes customizable retry and backoff behavior. Standard request types handle strings, JSON, and images, while custom request classes can support other response formats. Volley is intended mainly for short RPC-style operations that populate application interfaces rather than large downloads or continuous streams. This mirror is no longer maintained, and new projects should use Google’s official Volley distribution.

    IoTDB

    IoTDB

    Apache IoTDB

    Apache IoTDB (Database for Internet of Things) is an IoT native database with high performance for data management and analysis, deployable on the edge and the cloud. Due to its light-weight architecture, high performance and rich feature set together with its deep integration with Apache Hadoop, Spark and Flink, Apache IoTDB can meet the requirements of massive data storage, high-speed data ingestion and complex data analysis in the IoT industrial fields. In the scene of factories, there are tens of devices under LAN network. IoTDB can be installed on a local controller server in the factory to receive data from those devices. The local controller server (normal PC or workstation) with IoTDB can provide the ability to persist data and query data with SQL-like interface. In addition, with TsFile-Sync tool, TsFiles on the local controller can be transmitted to the data center equipped with IoTDB instance in the cloud.

    JavaMelody

    Monitoring of JavaEE applications

    The goal of JavaMelody is to monitor Java or Java EE applications in QA and production environments. The goal of JavaMelody is to monitor Java or Java EE applications in QA and production environments. It is not a tool to simulate requests from users, it is a tool to measure and calculate statistics on real operation of an application depending on the usage of the application by users. JavaMelody is open-source (ASL) and production-ready: in production in an application of 25 person-years. JavaMelody is easy to integrate in most applications and is lightweight (no profiling and no database). JavaMelody includes statistics of predefined counters (currently HTTP requests, SQL requests, jsf actions, struts actions, JSP pages, and methods of business façades if EJB3, Spring or Guice) with, for each counter.

    Logbook

    Logbook

    An extensible Java library for HTTP request and response logging

    Logbook is an extensible Java library to enable complete request and response logging for different client- and server-side technologies. It satisfies a special need by a) allowing web application developers to log any HTTP traffic that an application receives or sends b) in a way that makes it easy to persist and analyze it later. This can be useful for traditional log analysis, meeting audit requirements or investigating individual historic traffic issues. Logbook is ready to use out of the box for most common setups. Even for uncommon applications and technologies, it should be simple to implement the necessary interfaces to connect a library/framework/etc. to it.

    Metrics

    Metrics

    Capturing JVM and application-level metrics

    Metrics is a Java library which gives you unparalleled insight into what your code does in production. Metrics provides a powerful toolkit of ways to measure the behavior of critical components in your production environment. With modules for common libraries like Jetty, Logback, Log4j, Apache HttpClient, Ehcache, JDBI, Jersey and reporting backends like Graphite, Metrics provides you with full-stack visibility. The central library for Metrics is metrics-core, which provides some basic functionality. The starting point for Metrics is the MetricRegistry class, which is a collection of all the metrics for your application (or a subset of your application). Each metric is associated with a MetricRegistry, and has a unique name within that registry. A gauge is the simplest metric type. It just returns a value. If, for example, your application has a value which is maintained by a third-party library, you can easily expose it by registering a Gauge instance which returns that value.

    Simplify

    Simplify

    Android virtual machine and deobfuscator

    Simplify virtually executes an app to understand its behavior and then tries to optimize the code so that it behaves identically but is easier for a human to understand. Each optimization type is simple and generic, so it doesn't matter what specific type of obfuscation is used. Provides a virtual machine sandbox for executing Dalvik methods. After executing a method, it returns a graph containing all possible register and class values for every execution path. It works even if some values are unknown, such as file and network I/O. For example, any if or switch conditional with an unknown value results in both branches being taken. Analyzes the execution graphs from smalivm and applies optimizations such as constant propagation, dead code removal, unreflection, and some peephole optimizations. These are fairly simple, but when applied together repeatedly, they'll decrypt strings, remove reflection, and greatly simplify code. It does not rename methods and classes.

    Spring Security

    Spring Security

    Authentication and access-control framework

    Spring Security is a powerful and highly customizable authentication and access-control framework. It is the de-facto standard for securing Spring-based applications. Spring Security is a framework that focuses on providing both authentication and authorization to Java applications. Like all Spring projects, the real power of Spring Security is found in how easily it can be extended to meet custom requirements. Spring Security uses a Gradle-based build system. In the instructions, ./gradlew is invoked from the root of the source tree and serves as a cross-platform, self-contained bootstrap mechanism for the build. Be sure that your JAVA_HOME environment variable points to the jdk-11 folder extracted from the JDK download.
