    CloudTierSDK

    CloudTierSDK

    CloudTier Storage Tiering SDK

    The CloudTier Storage Tiering SDK is a Hierarchical Storage Management (HSM) file system filter driver development kit. It implements a data storage strategy that automatically migrates data between high-cost and low-cost storage media, optimizing storage efficiency and reducing both capital and operational expenses. This SDK offers a simple and cost-effective solution to seamlessly integrate your on-premises storage infrastructure with cloud storage. The migration of files to the cloud happens transparently and securely, with no disruption to existing applications or infrastructure. The SDK uses on-premises storage as Tier 0 (hot storage) and cloud storage as Tier 1 (cold storage). Cooler or less frequently accessed data is automatically moved to cloud storage, freeing up local storage capacity. Your applications can continue to access all files as if they reside locally—no changes to your code or workflow are required.

    CocoCommons

    Modern, cross platform library of functions used in CoCo software

    This is a modern set of libraries intended for use in software related to the Tandy Radio Shack Color Computer (the CoCo). Some functionality may also be useful in more general Motorola 6809 centered projects. CocoCommons provides a set of libraries for common tasks such as reading DECB and RBF filesystems, interpretting common file formats, and displaying CoCo-like screens. These are used extensively in the DriveWire 4 project and the upcoming nineserver project. In time it these libraries should implement most of the functionality now found in the Toolshed project.

    CollLib is a library of functions, interfaces, and base implementations, which eases everyday use of imperative programming principles in Java development. CollLib's released jar artifacts are available in the Maven central repository at: http://repo1.maven.org/maven2. If you use Maven (recommended), just add CollLib as a dependency in your project's pom.xml file (groupId=org.colllib, artifactId=colllib). Apart from the Maven distribution the CollLib binaries are also available in the "Files" section. When using the manual download from there, you also need to include the following jar files in your project: juel-api-2.2.7.jar, juel-impl-2.2.7.jar, commons-beanutils-core-1.8.3.jar and commons-logging-1.1.1.jar API: http://colllib.sourceforge.net/apidoc/ NEW: colllib switches to Java 8 starting with colllib 2.0. If you depend on an older VM-version, please stick to colllib-1.6.

    Colorful

    Colorful

    Android dynamic skin resurfacing library

    Colorful is an Android library aimed at simplifying the use of color and theme customization in Android applications by providing utilities for generating, manipulating, and applying dynamic color schemes at runtime. It abstracts away the complexity of Android’s standard theming system and gives developers a higher-level API for tasks such as tinting UI components, generating complementary color palettes, and producing visually consistent themes based on a primary color. With Colorful, you can create adaptable interfaces that respond to user preferences, branding requirements, or content-specific hues without boilerplate code spread throughout your UI layer. The library also includes support for contrast adjustments and accessibility concerns, ensuring generated palettes remain legible and compliant with usability guidelines. Because color theming is central to modern app design, Colorful helps teams implement sophisticated, dynamic visual systems while preserving maintainability.

    Competent Audio

    Competent Audio

    Machine graph audio engine for computer games

    Competent Audio (CA) is an audio engine suitable for video games. It is written in C, but is designed for interoperability with other languages. Windows and Linux binaries for x86 and amd64 are available. CA uses a machine graph model with support for arbitrary numbers of machines, limited only by the available system resources: - Samplers play back audio clips. - Mixers combine audio signals and optionally perform signal processing. - Sinks send audio signals to an output device. Stereo and mono sound output is supported via a slightly customized version of libsoundio 2.0. Audio clips can have arbitrary channel counts, and can be queued for streaming or dynamic music. CA contains a very simple embedded VM for running custom signal processors, allowing you to add custom DSP code (currently assembly language only) without compiling native code. Errors are reported using well-documented negative return codes, and CA attempts to handle expected errors gracefully.
