Hello World Java Polyglot

I wanted to see how much simpler native code integration has become with GraalVM's polyglot, when compared to JNI. It's less than 100 lines all up (including the POM). (I feel kinda stupid posting a "hello world" to HN, but this is a hell of an improvement.) Linux only at the moment.

Hello World Java Polyglot launched on March 7, 2023 with 15 votes, #1,789 of 5,007 launches that month and more than 75% of that year's launches. The site was not reachable when checked in September 2026.

In plain words

Hello World Java Polyglot demonstrates GraalVM's polyglot capabilities for integrating native code with Java. It shows how much simpler the process has become compared to traditional JNI approaches, accomplishing the task in under 100 lines of code including build configuration. The project is designed for Java developers exploring GraalVM's native code integration features and currently runs on Linux only.

    I Wrote a Book on Java2024 · ▲586

    https://www.manning.com/books/data-oriented-programming-in-j... This book is a distillation of everything I’ve learned about what effective development looks like in Java (so far!). It's about how to organize programs around data "as plain data" and the surprisingly benefits that emerge when we do. Programs that are built around the data they manage tend to be simpler, smaller, and significantly easier understand. Java has changed radically over the last several years. It has picked up all kinds of new language features which support data oriented programming (records,…

    Hi There, Erlang-RED has been my project for the last couple of months and I would love to get some feedback from the HN community. The idea is to take advantage of Erlangs message passing and low overhead processes to have true concurrency in Node-RED flows. Plus also to bring low-code visual flow-based programming to Erlang.

    Hi HN! For the past bit we’ve been building Flowglad (https://flowglad.com) and can now feel it’s just gotten good enough to share with you all: Repo: https://github.com/flowglad/flowglad Demo video: https://www.youtube.com/watch?v=G6H0c1Cd2kU Flowglad is a payment processor that you integrate without writing any glue code. Along with processing your payments, it tells you in real time the features and usage credit balances that your customers have available to you based on their billing state. The DX feels like React, because we wanted to bring…

  • Talanoa▲340

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

    I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
