    Any #java heads able to help here? My java is pretty limited. There has been work in the UpgradeProtocol method recently. This is the code that upgrades http 1.1 connections to http2 connections in #ApacheTomcat. I am trying to test a fix in stream handling, but I can't get the application to work. :/

    So I took a cursory look around https://dart.dev/ ... I think #Dart resembles #Java ... this may be why it has far less mindshare than #TypeScript and #CoffeeScript among "compiles to #JavaScript" languages.

    Odd to me that #Dart strings are UTF-16 instead of UTF-8. I’m sure there’s a legacy reason (was “Dart”:{https://dart.dev/} originally written in #Java?), but still, that seems backwards to me for a language created in 2011.

    @musicman Here's a #Java language thought. In general, many of the complexity and boilerplate issues associated with the language could be worked around, but one issue cannot: The language is owned and controlled by Oracle.

    It may be a fruitful field for several more years, but eventually, ORCL will extract every possible drop of profit out of the language and its ecosystem, bankrupting their paying customers and almost everyone else.

    Both ASF (Apache Software Foundation) and Eclipse Foundation are in the line of fire and are likely to become casualties.

    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.

    I know @pete ...but I didn't when we fediverse met.

    There have been a few others that have come and gone over the years, but mostly just twitter refugees that went back when they figured out the fail whale (which I think was them moving to #Java).

    @edythemighty and @marxistvegan are probably the two I spent the most time talking to here, but again, neither of them did I know IRL before fediverse. I still keep up with Edy, but he's just not in the fediverse.

    thinking about writing a #cycling training app, but not sure how exactly it fits into any of these. It could maybe fit in learning a new language, but if it's like "zero to app" in 3 months or something, I don't know how useful it will be. I mean, I have other stuff to do, but largely right now I am being paid to learn #Java (and Java tooling).

    Interestingly, 12 weeks is what this bootcamp uses: https://www.thesoftwareguild.com/coding-bootcamps/java-training/

    @musicman Not an answer, because I don't know, but look into #Java and time zones. I'd guess it probably has its own implementation of the Olsen #timezone database.

    My team is hosting a virtual conference in October (maybe it's September). I think it is just for current customers. A user group meeting of sorts.

    In any case, I don't know if the presentations themselves will see the public web, but I can certainly share here some of what I learn along the way.

    Basically any #freesoftware is fair game, although we don't typically do much with #bsd. What would you like to know about? #java #jenkins #configurationascode #cloud #orchestration #linux.

    I guess I need to figure out if it needs to be an application we support. We support a bunch of stuff though, so I wouldn't worry too much about that when suggesting topics.

    @musicman I don't think there was a #TomEE in 2004. I hadn't even heard of #Glassfish yet. I used regular #Tomcat (with #Apache and #IIS) at school, and even looked into a #Java based web host ... but the work schedule and commuting (and then traveling and #hotel_INET) just made it not doable.

    @clacke "Sounds like Oracle had been eyeing MySQL for far longer than I realized. Would they have even bought Sun if it weren't for MySQL?

    Is that even why Sun bought MySQL?"

    I'm sure that had something to do with why #MySQL became available for Sun to buy.

    First came the #Sleepycat purchase (followed by removal of the #BDB engine), then the #Innobase ( #InnoDB engine ) purchase, then #Sun purchased MySQL, then #IBM rejected Sun's attempt to get purchased, then Oracle purchased #Sun (along with its parts and products ... #Java, #Solaris, MySQL, and so on).

    By the way, whenever I need a MySQL compatible database, I select #MariaDB, to avoid #Oracle.

    Sort of off-topic: Do you remember when MySQL had a distribution deal for an open source version of SAPDB named MaxDB? It didn't seem to last long (a year or two?). I'm sure sales were much lower than SAP expected.
