Kitten
A statically typed concatenative systems programming language
Kitten is an experimental, concatenative programming language that blends Forth/Joy-style stack programming with modern static typing and effect tracking. Programs are composed by chaining small words that transform a typed stack, and the compiler uses type inference to ensure compositions are valid. The language explores disciplined handling of side effects, aiming to separate pure transformations from operations that perform I/O or mutate state. Its design encourages small, reusable building blocks that compose cleanly, while still permitting low-level control where performance matters. The implementation targets efficient compiled code and investigates how advanced type systems can improve reliability in a stack-based language. As a research project, Kitten serves both as a language to experiment with and as a vehicle for ideas about safety and structure in concatenative programming. -

Kotlin JDSL
Kotlin library that makes it easy to build and execute queries
Kotlin JDSL is a Kotlin library that makes it easy to build a query without a generated metamodel. There are many libraries that use an annotation processing tool (APT) to do the job. However, with the APT, you have to recompile whenever the name or type of field in an entity or a table class is changed. Kotlin JDSL provides a domain-specific language (DSL) based on KClass and KProperty to help you easily build queries without such inconveniences from the APT. Kotlin JDSL does not provide an executor or a wrapper class as it is designed to help you build and execute queries with the library you are using. -

Laravel Echo
Laravel Echo library for beautiful Pusher and Ably integration
In many modern web applications, WebSockets are used to implement realtime, live-updating user interfaces. When some data is updated on the server, a message is typically sent over a WebSocket connection to be handled by the client. This provides a more robust, efficient alternative to continually polling your application for changes. To assist you in building these types of applications, Laravel makes it easy to "broadcast" your events over a WebSocket connection. Broadcasting your Laravel events allows you to share the same event names between your server-side code and your client-side JavaScript application. Laravel Echo is a JavaScript library that makes it painless to subscribe to channels and listen for events broadcast by Laravel. You may install Echo via the NPM package manager. -

Let
Annotation based API flavored with AOP to handle Android models
Annotation-based simple API flavored with AOP to handle new Android runtime permission model. If you check Google's Samples about the new permission model, you'll see a lot of boilerplate code for requesting, handling, and retrying the request for required permissions. Let will minimize the boilerplate code you have to write for requesting and handling permissions and hence help you keep your code more readable. Let will check these annotated methods and execute them unless the permissions required are granted; otherwise, Let will put on hold the method execution on and request these permissions at runtime. After examining the permission request result, Let will execute the method already put on hold only if the permissions are granted by user. -

LiteBox
A security-focused library OS supporting kernel execution
LiteBox is a security-focused “library OS” sandboxing project that aims to shrink the interface between an application and its host environment to reduce attack surface. Instead of relying solely on broad OS-level permissions, it focuses on isolating workloads by tightly controlling the boundary where code interacts with host services and system resources. The design emphasizes interoperability across different integration layers, describing a separation between “North” shims (how apps or runtimes plug in) and “South” platforms (where the sandbox runs), which helps the system adapt to multiple deployment contexts. A key aspect of the project is that it targets both kernel-mode and user-mode scenarios, enabling experimentation with different trust and performance tradeoffs. The repository positions LiteBox as a foundation for building hardened execution environments where untrusted or semi-trusted components can run with reduced privileges and a minimized host interface. -

MIT License
Hosted MIT License with details controlled through this repo
The MIT License repository is a simple GitHub project that hosts the full text of the MIT License and provides a stable reference for developers who want to include permissive licensing details in their work. The MIT License itself is one of the most widely used open-source licenses because it allows reuse, modification, distribution, and even proprietary use, as long as copyright notices and license texts are preserved. This repository offers an easy way to copy the license text, understand its legal language, and see example usage in a context that is separate from any specific software project. It can also be useful for automated tooling and templates where a standard license file is needed across multiple repositories or as part of a code generation process. While not a software library or application, the repository serves an important role in open-source governance by centralizing a commonly adopted license with clear formatting.
