Agree totally with that. I've been programming Java for the last 6 months. While it's very easy to write and get complex functionality working quickly, it is just so sloooooow. Garbage collection is just a barely controlled memory leak.
The whole idea of garbage collection is a good one.. if implemented properly but there is the inherent problem that for garbage collection to work properly it has to use up certain cpu time slices.... this can lead to not just the programming running slowly but slowing down the whole system on a process that never seems to work properly [well.. in Java's case]. You can do some pretty cool and complex stuff with Java and you can code it quickly but as regards execution speed.... X| Regards, Brian Dela :-)

I've been using Java a lot here lately and while I do enjoy programming it* I find it just way too slow. Having two or 3 java apps [not my apps] running can kill my machine [2.4 P4,512MB Ram]. For example if I try to use eclipse and tomcat on this machine for any reasonable length of time [upwards of 6 hours] both apps are using over 100MB each after that length of time!!! It's ridiculous! And yes.. I've tried different VM's to see if it made a difference and it doesn't. The garbage collection just doesn't seem to work! *I'll probably be shot for saying that Regards, Brian Dela :-)
I think the GC works just fine, from Java 1.2 anyway, but there are certain pitfalls to avoid when writing for a garbage collected environment and I have seen some gross examples of that in C# too... First: GC does NOT mean resource handling, I used over a week on my last contract cleansweeping a C# application for unreleased db connections. The silly thing would leak up to a hundred connections pr. second! I wrote a Java server once running on a HP-UX box, and I never found out how long it could run without getting restarted, because the app had to be stopped every week due to problems with external modules. As for performance on that one: Our resident C programmer insisted that it HAD to be a C app, because he couldn't believe that speed otherwise. But then again, it wasn't a GUI app. "After all it's just text at the end of the day. - Colin Davies "For example, when a VB programmer comes to my house, they may say 'does your pool need cleaning, sir ?'

I'm not having trouble with any of my own applications... not big enough to ever be using 100MB... But eclipse, Tomcat... even the J2EE Application Deployer [Sun's own one] are ridiculous... really... When I used the J233 Application Deployer I had to more or less shut everything else down.. now if Sun can't get it right then, to me, it's all a bit messed up. jan larsen wrote: it wasn't a GUI app. Yep.. GUI seems to be a problem with Java*.. it still can run slowly with non-GUI apps [e.g. Tomcat] but a lot of non-GUI apps run fine. * Oh.. and Java GUI's look sh*te Regards, Brian Dela :-)

In bad mood and don't want to spoil the party, but: Let me ask you guys: Am I the only one here that recently feel like all that .NET hype is just and only the hype?... At least on desktop site?... Am I alone on that? As I see obvious advantages of using CLR on server site, I personally completely missunderstand and disagree with the concept on the client: Yes sure, language is important, but real serious client products evolving usually not in one night, but growing slowly and utilizing OS specifics, becoming at some point contrary to OOP and still fulfilling the task. Could anybody help me finding out recent CLR implementations of something more complicated then just UserControl and/or Tool for software development. Something like small Excel and/or ActiveX(or WinForm) TestContainer and etc... Maybe some application resolving some real business problems... I'm talking about DeskTop (Client site) only solution. Thank you.
Don't ask so many questions. I've been programming over-hyped technologies for nearly 20 years and I've never gone hungry. "More capitalism, please..."

The rate of breaking changes is so high that .NET 2.0 due in 2004 will again break project files, source code, behaviors, etc. The ROI is halfed from published expectations IMHO.
I said "fun", I didn't say "hassle free", "fully backwards compatible" or "a cure for cancer" ;) I'm fully aware there are problems moving large projects to .NET, but that doesn't mean I can't enjoy working in .NET. cheers, Chris Maunder

Now, that is funny! BTW, I don't care if there are breaking changes that make my applications better and more secure. I believe breaking changes are unavoidable as they're tied to evolution and improvement.
The nice thing about C++ is that only your friends can handle your private parts.

I believe breaking changes are unavoidable as they're tied to evolution and improvement. I don't buy this. Upgrading the source code is hardly part of the development cost allowed by your company. Actually, it's always assumed that compilers don't change. Although at my ocpany we have been using DevStudio 6.0 for a bunch of years, I foresee that the day we upgrade to 7.x we'll have a lot to pay in terms of unavoidable upgrade. On the other hand, in software companies you focus on your business value, not on the fact that the compiler has drastically changed.

I'm told that the 1.0 to 1.1 project break was due to poor planning in the project format in 1.0, and that 1.1 fixes this so they won't break again. I'm in Redmond this week so I'll snoop around and see if I can get some details on whether 2.0 will break things. cheers, Chris Maunder

And the worst part is that Microsoft developed another "darling" language to go with it. It was bad enough that the VB programmers got everything handed to them on a platter and the C++ programmers had to wait and jump through hoops. Now C++ takes another hit with the managed extensions which turn it into an abomination. Which of course is Microsoft's strategy to get you to switch to C# where it's easy again and it sort of looks like C++ if you never used much of the language. The need for a good library is clear. The standard library is Java's only saving feature. If C++ had as comprehensive of a standard library, Java would never have caught on IMHO. Tim
