MeGit
Standalone Git GUI based on EGit
Looking for a powerful, yet easy-to-use, fully open-source user interface for git? Well, there are plenty of options. One of our favorites is EGit. However, EGit is actually a plug-in for Eclipse rather than a standalone tool, such as GitKraken, etc. Nevertheless, even in projects where we actually use other editors or IDEs than Eclipse, we often found ourselves firing up an Eclipse IDE with EGit just to handle more complex git branch operations, for analysing the git history, and so on. This made us think, wouldn't EGit be a great git standalone tool if it would be... well, an actual standalone tool? That's exactly what MeGit is: a minimal standalone application that contains just enough to run EGit conveniently. Nice visualization of the git history making it easy to keep a good overview when analyzing, merging or rebasing branches, cherry-picking commits, changing the git history, etc. -

QR Code generator library
High-quality QR Code generator library in Java, TypeScript/JavaScript
This project aims to be the best, clearest library for generating QR Codes. My primary goals are flexible options and absolute correctness. The secondary goals are compact implementation size and good documentation comments. This work is an independent implementation based on reading the official ISO specification documents. I believe that my library has a more intuitive API and shorter code length than competing libraries out there. The library is designed first in Java and then ported to TypeScript, Python, Rust, C++, and C. It is open source under the MIT License. For each language, the codebase is roughly 1000 lines of code and has no dependencies other than the respective language’s standard library. -

Spring Boot Examples
Spring Boot tutorials, technology stack example code
spring-boot-examples is a collection of small, runnable projects that teach Spring Boot “by example,” emphasizing minimal dependencies and practical, copy-pasteable patterns. The repository provides multiple standalone demos (e.g., web, scheduling, persistence, messaging, caching, Docker) to help beginners quickly grasp common components and idioms. The author notes that all examples have been updated to Spring Boot 3.0, with earlier 1.x and 2.x code paths kept accessible for reference. Each sample focuses on a single topic—such as Web MVC, WebFlux, Thymeleaf, JPA/MyBatis CRUD, file upload, Redis/MongoDB, RabbitMQ, and containerization—so you can learn one concept at a time and compose them later. There are also demos for testing, packaging (JAR/WAR), and Docker Compose scenarios that combine Spring Boot with Nginx and MySQL. If you want additional topics covered, the maintainer invites requests via issues so the set can keep growing with the community’s needs. -
