After two months of C#, I remember thinking to myself, quite clearly, "Oh, thank God, the nightmare is over."

Debuggers that worked. Native calling systems that actually interoperated well. A set of classes that weren't horribly overdesigned and under-implemented.

Best of all, no culture that insisted on factories that made factories that made factories.

Writing Java on phone platforms is fine. But the enterprisey stuff is death on roller skates.

Hey, if you can stand it (my cousin does), then you might make a bunch of money. My cousin spends six months hacking Java for a bank, then six months vacationing. I prefer to do stuff that doesn't make me contemplate washing dishes for a living again.

.NET has its warts, but it's not cancerous the way Java turned out to be in the hands of the architecture astronauts.

I have spend most of my career doing Java6 JEE6 and modern Spring and it all feels quite modern. I did a lot of C# at University and it is a good language and platform but I don't think it's better than Java. New / modern Java is fine, it's old java that you want to avoid.

imo C# is an improved java, but C# open source ecosystem is just anemic compared to java.

By that logic everyone would still be using Cobol or Fortran for new development. Moreover neither Rails, Django, or Grails are brand spanking new anymore. Those projects are mature. If you don't want to stray too far away from the jvm comfort zone, Grails is actually built on top of Spring and Hibernate and it's still maintained by the Spring team.

IntelliJ supports JavaScript and JSP debugging as well.

Client-server development using EJB 3.x is way much better, cleaner, and simpler than .NET, sorry, this is something that I don't think you can argue elegantly.

.NET culture when it comes to open source is sub-par while Java is very rich. Spring, Tomcat, Jetty, Hadoop, HBase, Eclipse, NetBeans, Maven, Ant, the list goes on. These are mature and high profiled open source projects wherein .NET I have never seen an open source project reached that level of acceptance.

While Java has this sub-culture of factories that made of factories. .NET has this culture of fighting with the latest and grandest libraries that Microsoft launched once every 6 - 12 months.

Enterprise .NET is not at the level of Java yet (compare Message Queue, remoting, security, and other capabilities .NET are still lagging).

.NET has its cancer in its own way.

I honestly believe that you have not used Java that deep professionally.

The nightmare for me has been over in the mid-nineties, when I discovered Unix through Linux.

There's no way I'll ever be going back to working on Windows. I'd rather go work as a plumber or a truck driver (not that there's anything wrong with that) then have to work on Windows ever again.

C# / F# might be interesting, but using any Windows as my OS is a big no-no. Never this nightmare again.

And, nearly 20 years later, the great thing is that a lot of devs previously working on Windows are now working on OS X (anybody disputing that trend is a fool).

Major win for Unix with both Linux and OS X. Not to mention all the devices running either iOS or Linux / Android.

The nightmare is over: Windows shall never be the OS powering all these servers and devices out there and hence .Net shall never be the dominant platform.

It's not that .NET has its warts (it does), it's that Windows has its ugly warts and I'll never ever be using that inferior OS ever again and I'll never ever again will be forced to deploy on an Microsoft stack.

In the mid-nineties I considered quitting IT. And Linux saved me. And now OS X. Thanks.

These days, you can be a C# developer without having to do an ounce of "Microsoft Stack" programming if you didn't want to.

Java looks bad? You're probably talking about certain swing applications which are now very rare on the desktop.

Java is slow? You clearly have no idea how fast the JVM can interpret and JIT java nowadays.

Java is insecure? You're mainly talking about applets which are an ancient technology on their way out (slowly). In terms of actual JVM security. Every product has its security issues.

You seem very ignorant, your java experience is probably from the past e.g. J2EE1.4 and old swing apps.

Modern Java is an good language on a great platform. There's a reason why it runs some of the worlds biggest ecommerce sites and worlds fastest trading desks.

Pycharm is an example of one of the apps I am talking about. It just feels like it struggles at times, eventhough I have a fairly new machine.

Java was the first language I learned while going through college but I find the verbosity to be irritating.

Swing is probably going to be slower (maybe?) than some native windowing framework.

But Java as a language running on the JVM is certainly not slow.

I've just been looking up pycharm and it seems that the slowness issues are to do with things like opening files and doing parsing. These things are likely to be slow for anything but the language they are written in.

It depends on your POV. I've had to deal with an enterprise Java crapware app that was essentially a terminal emulator for an old mainframe... except that it required more than 4GB of memory on the desktop to work appropriately.

The mainframe itself has 2GB of RAM.

Fun fact, several Windows versions have included a security mitigation technology called ASLR (Address Space Layout Randomization) that breaks a large majority of exploits and raises the bar significantly. Exploit developers and penetration testers love Java, because any machine that has it installed (most of them) breaks ASLR, re-enabling all of those exploits that Microsoft had otherwise mitigated.
