  • Java at 30: The Genius Behind the Code That Changed Tech

    Another way to look at it based on coming across it in enterprise:

    How did he build something adopted by so many enterprises?

    It does some things at scale very well and has been afforded the performance improvements of very smart people for 30y.

    It’s not to say the language isn’t verbose, one of my favourite features was the ability to write code in other languages right inside the a Java app pretty well in-line by using the JVM, thanks to JSR-223.

    It was possible to write Ruby or Python code via Jruby or Jython and run it in the JVM.

  • Shoes makes building little graphical programs for Mac, Windows, Linux simple
    13 projects | news.ycombinator.com | 23 Feb 2024
    As someone who has looked at Shoes several times but never dove in, it's confusing how Shoes 4 has been the "preview version" of Shoes for, like, a decade or more. It made me actively avoid getting invested in Shoes 3 (the release promoted on the linked website) because Shoes 4 requires JRuby and I am happy with CRuby (the Ruby interpreter most people think of when they hear "Ruby").

    http://www.rubydoc.info/github/shoes/shoes4

    No disrespect to the developers but to me it feels like taking over a GUI toolkit created "to teach programming to everyone" (to quote the Shoes 4 readme) and making it depend upon a super-complicated enterprise-focused Ruby was sort of Missing The Point™ in a huge way.

    Heck I couldn't even switch to JRuby if I wanted to because I <3 Ractors and JRuby still lacks CRuby 3.0 feature parity: https://github.com/jruby/jruby/issues/7459
