I just read through the introductory tutorial for #Laminas, the community-based continuation of the #PHP #Zend framework.

Sacred bovine! For the simplest task imaginable, they're using factories.

It is as if someone in the PHP world said "We don't get enough respect, so we must copy #Java's JEE enterprisey stuff".

@geniusmusing Years ago, I was working on some #Java stuff. Seemed to be more complicated than necessary, but many of the things I was using at the time (XMPP server, various client / desktop software, Tomcat) were Java based.

Then three things happened:
1. $EMPLOYER made a strong turn into the Microsoft ecosystem, displacing most of the Java apps we used
2. ${NYSE[ORCL]} bought Sun … and got Java, MySQL, and Solaris, along with a few other things. As expected, Oracle’s changes were overwhelmingly negative … but then, Sun was having trouble making money, while Oracle probably owns the US Mint.
3. Soon after Oracle’s takeover, some really severe security holes started appearing in Java, eventually resulting in Java’s removal from browsers far earlier than notoriously insecure Flash’s removal

I don’t trust Microsoft much more than I trust Oracle, so Microsoft’s Java replacement ( C# ) is mostly out of bounds for me, though I like much of what I see in #PowerShell.

ok, I am now analyzing dump. customer is on #java 8 181. That's pretty old. I'm not sure those are really changelogs I want to wade into, but I guess I will. Does that version jump out to anyone regarding performance?

is there a jar for the #eclipse Memory Analyzer (aka #MAT)? I can't get .apps to open on my work mac, but I can open jars from the command line.

I attempted to edit the ini file in the .app, but that did not resolve the issue.

@musicman That I don’t know how many of them are #FLOSS, but tossing “Java thread dump analyzer” into DDG got me a few different products, including one by IBM and one by Spotify.

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).
