    Naturally depends on the use case, yet they work good enough to be in business for 20 years.

    Unfortunely the best well known, Excelsior JET, is no longer in business, most likely due to GraalVM and OpenJ9 being available as free beer, while PTC, Aicas Codename One are safe in their domains.

    There is also RoboVM (https://github.com/MobiVM/robovm) as free beer, however it actually started as a commercial product, and the acquisition from Xamarin kind of stagnated it (naturally).

  • Can't Reproduce a Bug?
    1 project | dev.to | 1 Aug 2023
    At Codename One, we were using App Engine when our daily billing suddenly skyrocketed from a few dollars to hundreds. The potential cost was so high it threatened to bankrupt us within a month. Despite our best efforts, including educated guesses and fixing everything we could, we were never able to pinpoint the specific bug. Instead, we had to solve the problem through brute force.

    We use ParparVM which we wrote. It compiles a subset of Java 8 (sort of) to native by translating the bytecode to C and passing that through XCode. The reason we took this path and not the path of "direct to native", is that it allows for future compatibility.

  • Ask HN: What are some unpopular technologies you wish people knew more about?
    56 projects | news.ycombinator.com | 2 Dec 2023
    (1) Zulip Chat - https://zulip.com/ - seems to be reasonably popular, but more people should know about it

    I’ve been using it for over 5 years now [1], and it’s as good as ever. It’s way faster than any other chat app I’ve used. It has a good UI and conversation model. It has a simple and functional API that lets me curl threads and write blog posts based on them.

    (only problem is that I Ctrl-+ in my browser to make the font bigger – I think it’s too dense for most people)

    (2) re2c regex to state machine compiler - https://re2c.org

    A gem from the 90’s, which people have done a great job maintaining and improving (getting Go and Rust target support in the last few years). I started using it in 2016, and used for a new program a few months ago. I came to the conclusion that it should have been built into C, because C has shitty string processing – and Ken Thompson both invented C AND brought regular languages to computing !!

    In comparison, treesitter lexers are very low level, fiddly, and error prone. I recently saw dozens of ad hoc fixes to the tree-sitter-bash lexer, which is unsurprising if you look at the structure of the code (manually crawling through backslashes and braces in C).

    https://github.com/tree-sitter/tree-sitter-bash/blob/master/...

    These fixes are definitely appreciated, but I think it indicates a problem with the model itself.

    A few more truly in the vibe of open source projects not advertising their hosting providers: https://plane.so/ , https://element.io/ , https://www.loomio.com/ , https://zulip.com/ , and it keeps going... Very few open source projects, in the FOSS sense, are advertising their hosting provider.

    I was so excited to see this happen!

    I'm not a customer of yours, but your blog posts inspired me a lot. Your journey through quitting caffeine is a great and heartening read.

    I've got two things to say;

    1) Will you consider source-availabling the web portal (app.keygen.sh) too? Some enterprises could use it for easy management/support for custoner's licenses. Although now that I think about it, it could also discourage custom, more suitable implementations for each use-case... I'm torn on this one. I would like to see it available on GitHub too just out of curiosity too. It's very beautiful.

    2) For a team + customers' chat, I cannot recommend Zulip enough. It's a joy to use and has the most innovative chat system I've ever seen. https://zulip.com

    I hope your business keeps prospering!
