    HikariCP

    HikariCP

    A solid, high-performance, JDBC connection pool at last

    HikariCP is a high-performance JDBC connection pooling library designed to offer minimal overhead and maximum throughput. It aims for simplicity and stability, concentrating on fast connection acquisition and minimal latency under load. Its internals manage a pool of connections aggressively but smartly, with options such as leak detection, timeout thresholds, and adaptive connection retirement. Because it avoids heavy internal locking, it scales well in high-concurrency environments, making it a popular choice in microservices and high-throughput web backends. Metrics and instrumentation hooks (for example, via Dropwizard or Micrometer) allow runtime visibility into pool usage and health. HikariCP’s focus is on doing the essential work of pooling correctly and efficiently, rather than bundling extraneous features.

    Linux Deploy

    Linux Deploy

    Install and run GNU/Linux on Android

    This application is open source software for quick and easy installation of the operating system (OS) GNU/Linux on your Android device. The application creates a disk image or a directory on a flash card or uses a partition or RAM, mounts it and installs an OS distribution. Applications of the new system are run in a chroot environment and working together with the Android platform. All changes made on the device are reversible, i.e. the application and components can be removed completely. Installation of a distribution is done by downloading files from official mirrors online over the internet. The application can run better with superuser rights (root). The program supports multi language interface. You can manage the process of installing the OS, and after installation, you can start and stop services of the new system (there is support for running your scripts) through the UI. The installation process is reported as text in the main application window.

    AWS SDK for Java 2.0

    AWS SDK for Java 2.0

    The official AWS SDK for Java - Version 2

    The AWS SDK for Java v2 is a modern, modular rewrite that reduces dependencies, improves performance, and embraces non-blocking I/O. Each AWS service ships as its own small artifact, so applications include only what they use, cutting footprint and cold-start time. The SDK provides both synchronous clients and a high-performance asynchronous stack built on event-driven HTTP, enabling reactive pipelines and high-throughput services. Models are immutable and builders are pervasive, leading to safer code and clearer intent. Credential providers, region resolution, retries, and paginators are redesigned with extensibility in mind, and integrations are available for common observability and HTTP client choices. For teams starting new Java projects on AWS, v2 is the default choice due to its modularity, improved ergonomics, and better runtime characteristics.

    BedrockConnect

    BedrockConnect

    Join any Minecraft Bedrock Edition server IP on Xbox One

    On Minecraft Bedrock Edition, players on Xbox One, Nintendo Switch, and PS4/PS5 are limited to playing on 'Featured Servers' approved by Mojang/Microsoft. These players are not able to join servers via an IP/address. This is an issue for me and others, as the server community on Java edition was one of the major parts that made Minecraft what it was, and what also made the servers that are now considered 'Mojang Server Partners' what they are today. I wanted to fix this, so I made a solution that anyone can set up easily.
