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. -

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. -

Kord
Idiomatic Kotlin Wrapper for The Discord API
Kord is still in an experimental stage, as such we can't guarantee API stability between releases. While we'd love for you to try out our library, we don't recommend you use this in production just yet. Kord was created as an answer to the frustrations of writing Discord bots with other JVM libraries, which either use thread-blocking code or verbose and scope-restrictive reactive systems. We believe an API written from the ground up in Kotlin with coroutines can give you the best of both worlds: The conciseness of imperative code with the concurrency of reactive code. Aside from coroutines, we also wanted to give the user full access to lower-level APIs. Sometimes you have to do some unconventional things, and we want to allow you to do those in a safe and supported way. -

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. -
