Hacker Scripts
Based on a true story
Hacker Scripts is a cheeky collection of small automation scripts and language ports collected under the tagline “Based on a true story.” The repository gathers playful utilities (originally shell and Ruby scripts) that automate short, real-world tasks — for example, sending a quick “late at work” text when SSH sessions are active, firing off an automated “I’m sick / working from home” email on certain mornings, or even talking to a networked coffee machine to start brewing at precisely the right moment. The README explains the origin story and highlights several canonical scripts and provides usage notes such as required environment variables and cron examples for scheduling. Contributors have provided implementations and ports in many languages and folders (shell, Ruby, Python, Node, Perl, PowerShell, Go, Java, etc.), and the project explicitly welcomes pull requests that add additional language implementations. -

Image Picker Library for Android
Image Picker for Android, Pick an image from Gallery
Easy to use and configurable library to Pick an image from the Gallery or Capture an image using a Camera. It also allows to Crop and Compress the Image based on Aspect Ratio, Resolution, and Image Size. Almost 90% of the apps that I have developed have an Image upload feature. Along with the image selection, Sometimes I needed a crop feature for my profile image for that I've used uCrop. Most of the time I need to compress the image as the image captured from the camera is more than 5-10 MBs and sometimes we have a requirement to upload images with specific resolution/size, in that case, image compression is the way to go option. To simplify the image pick/capture option I have created the ImagePicker library. I hope it will be useful to all. -

kotlinx.coroutines
Library support for Kotlin coroutines
Library support for Kotlin coroutines with multiplatform support. Kotlin, as a language, provides only minimal low-level APIs in its standard library to enable various other libraries to utilize coroutines. Unlike many other languages with similar capabilities, async and await are not keywords in Kotlin and are not even part of its standard library. Moreover, Kotlin's concept of suspending function provides a safer and less error-prone abstraction for asynchronous operations than futures and promises. kotlinx.coroutines is a rich library for coroutines developed by JetBrains. It contains a number of high-level coroutine-enabled primitives that this guide covers, including launch, async and others. Coroutines can be thought of as light-weight threads, but there is a number of important differences that make their real-life usage very different from threads. -

Appyx
Model-driven navigation + UI components with gesture control
Appyx is a modern navigation and UI framework for Jetpack Compose and Compose Multiplatform that introduces a model-driven approach to building application navigation and interactive interfaces. Unlike traditional navigation libraries that rely on predefined patterns such as back stacks, Appyx allows developers to define their own navigation models, giving them full control over how screens and UI elements transition and interact. This model-driven paradigm separates navigation logic from UI rendering, making navigation state testable, reusable, and easier to maintain in large applications. The framework also supports advanced transition animations and gesture-driven interactions, enabling developers to create highly dynamic and visually rich user experiences beyond standard navigation flows. -
