title: lnxw48a1: lnxw48a1 favorited something by musicman: well, "enterprise" is largely a bad word in the startup space, to be equated with slow and/or complicated. I am having a related argument about Java. Maybe it is true that the Java ecosystem is too complicated. I was just yesterday unable to get something to work in IntelliJ and I have no idea why. It works in #Eclipse. In any case, I think the Java-naysayers probably don't know about things like https://quarkus.io/ I think there is a good argument about not using C or C++ for a startup, unless you are doing something that requires realtime, but I don't see the argument with Java. I think Java had years of uncertainty after the Sun acquisition, and #Java 8 certainly has issues with modern practices, but Java 8 came out before K8s. Considering #K8s came out the same year as Java 8 and #Mesos had been presented first 5 years earlier, it's easy to say that Java 8 was a missed opportunity. That said, a lot of things you would have liked to see in Java 8 came in Java 9. Thank you for coming to my TED talk.

title: lnxw48a1: @musicman That sounds like a good idea. Being that this _is_ #Java, also take a good look at the command line and environment variables needed for starting it. In the olden days, variables like $JAVA_PATH and $CLASSPATH had to be defined before the "java -jar somejarfile.jar" command ... some variables were small enough to define on the command line with "-Dsomevar=somevalue".
