  • Selenium WebDriver

    A browser automation framework and ecosystem.

    Project mention: What is Playwright? | | 2023-10-11

    While similar to Puppeteer, Cypress, and Selenium, there are some differences. Let’s find out what they are.

  • InfluxDB

    Collect and Analyze Billions of Data Points in Real Time. Manage all types of time series data in a single, purpose-built database. Run at any scale in any environment in the cloud, on-premises, or at the edge.

  • Graal

    GraalVM compiles Java applications into native executables that start instantly, scale fast, and use fewer compute resources 🚀

    Project mention: Crash report and loading time | /r/fabricmc | 2023-11-15

    I'm also using GraalVM if that's of any help.


    ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files.

    Project mention: Library to parse slash commands with validation? | /r/dotnet | 2023-06-02


  • Deeplearning4j

    Suite of tools for deploying and training deep learning models using the JVM. Highlights include model import for keras, tensorflow, and onnx/pytorch, a modular and tiny c++ library for running math code and a java based math library on top of the core c++ library. Also includes samediff: a pytorch/tensorflow like library for running deep learning using automatic differentiation.

  • aws-doc-sdk-examples

    Welcome to the AWS Code Examples Repository. This repo contains code examples used in the AWS documentation, AWS SDK Developer Guides, and more. For more information, see the file below.

    Project mention: Stubbing AWS Service calls in Golang | | 2023-08-15

    So I did some more research and I found the awsdocs/aws-doc-sdk-examples repo. This repository used a testtools module. So I started an experiment to see how I could use this module. I refactored the code as followed:

  • beam

    Apache Beam is a unified programming model for Batch and Streaming data processing.

    Project mention: Releasing Temporian, a Python library for processing temporal data, built together with Google | /r/Python | 2023-09-17

    Flexible runtime ☁️: Temporian programs can run seamlessly in-process in Python, on large datasets using Apache Beam.

  • Onboard AI

    Learn any GitHub repo in 59 seconds. Onboard AI learns any GitHub repo in minutes and lets you chat with it to locate functionality, understand different parts, and generate new code. Use it for free at

  • QR-Code-generator

    High-quality QR Code generator library in Java, TypeScript/JavaScript, Python, Rust, C++, C.

    Project mention: How to make a QR code with Stable Diffusion | | 2023-06-11

    The funny thing is that no-one AFAICT has realized that the same content can be encoded in different-looking QR codes. Beside the obvious (different error-correction levels), the content itself can be changed while maintaining its semantic meaning (e.g. "", "HTTPS://EXAMPLE.COM/foo", or "HtTpS://eXaMpLe.CoM/foo" are all semantically identical) and even the QR encoding itself can be tweaked (e.g. by changing the version and mask, see the demo on Each combination would yield a different-looking QR code that would encode the same meaning, and it could therefore allow the diffusion models even greater freedom.

    I'm sure somebody will get to this soon.

  • open-location-code

    Open Location Code is a library to generate short codes, called "plus codes", that can be used as digital addresses where street addresses don't exist.

    Project mention: A Critical Analysis of the What3Words Geocoding Algorithm | | 2023-09-02

    Pluscode is a trademark. The actual standard is called "open location code" and is unrestricted -

  • Apache Avro

    Apache Avro is a data serialization system.

    Project mention: How do you update an existing avro schema using apache avro SchemaBuilder? | /r/codehunter | 2023-06-09

    I am testing a new schema registry which loads and retrieves different kinds of avro schemas. In the process of testing, I need to create a bunch of different types of avro schemas. As it involves a lot of permutations, I decided to create the schema programmatically.I am using the apache avro SchemaBuilder to do so.

  • javacpp-presets

    The missing Java distribution of native C++ libraries

    Project mention: Any library you would like to recommend to others as it helps you a lot? For me, mapstruct is one of them. Hopefully I would hear some other nice libraries I never try. | /r/java | 2023-05-27

    JavaCPP and presets for working with JNI

  • AndroRAT

    A Simple android remote administration tool using sockets. It uses java on the client side and python on the server side

  • Project-Euler-solutions

    Runnable code for solving Project Euler problems in Java, Python, Mathematica, Haskell. (by nayuki)

  • sedona

    A cluster computing framework for processing large-scale geospatial data

    Project mention: Show HN: TG – Fast geometry library in C | | 2023-09-22

    This is awesome! I wonder how feasible is it to include TG in Apache Sedona (

    Although Sedona runs as a distributed system, but TG may speed local in-memory geometrical computation for each worker node. Let me know your thoughts!
