I don't like Java myself, but that's mainly because it is slow to load and doesn't integrate very well with other application on my system.

Having the Java VM running as an other operating system makes a lot of sense.

IIRC ARM for example created a CPU feature which improved java performance by a huge factor. I'm surprised that Intel/AMD hasn't jumped on the bandwagon - especially for the server space.

Seems for the 0.3 release they are trying to integrate a "user friendly desktop environment" Thu, 27 Sep 2007 20:39:00 GMT donotreply@osnews.com (horsnell) Comments http://osnews.com/thread?274988 http://osnews.com/thread?274988 The argument is normally because they consume more power or that they add too much to an already bloated chip; but given how things have shrunk - I don't see the harm. I mean, there are things like XML accelerators, cryto off loading boards and tcp/ip off loading. A CPU that can process Java quicker would certainly be a benefit rather than a pointless addition.

I hoped Microsoft dared to do this step with Windows Vista. But it has become a YAWN (Yet Another Windows Nt).

Now take your phone and load a 3D Java game and meditate on Java-FAST again.

And a pretty picture: Java is OK, it's portable, scalable, standardized, runs pretty applications, servers, watches ... you can run Java applications on Iphone Etc.

Fri, 28 Sep 2007 11:11:00 GMT donotreply@osnews.com (jessta) Comments http://osnews.com/thread?275061 http://osnews.com/thread?275061 well, thats not entirely correct. An empty class (only a main method) starts as fast as releasing the enter key (P4, 3.2). However starting the UI (Swing, et al) takes a bit longer (empty class with a single line like: JOptionPane.showInputDialog("testing");)
approx 2 seconds to start - and 3 to shutdown (!?)

I am also seeing similar times with .net (why is .net never flamed for speed issues??) and I guess this is true with most - all? - VM based languages.

using Java 1.6 on windows btw.Edited 2007-09-28 11:23 Fri, 28 Sep 2007 11:23:00 GMT donotreply@osnews.com (Matzon) Comments http://osnews.com/thread?275063 http://osnews.com/thread?275063 I will not argue the meaning of the word slow, bot look around - many applications (MS Windows, OpenOffice, Adobe Reader, Gnome...) have non comparatively larger problems with loading. It is a technical issue, it can be solved, and it was solved for whom it mattered - check your mobile again.

And as I said in previous post that Horlveda deleted from the thread: Java is just fine.

But since JNode runs everything on the JVM, it would of course be already loaded at the time you even log in to the system. VM loading time will only increase boot time, not the time to start an application.

(Of course, pre-loading the JVM could be done on any other system too) Fri, 28 Sep 2007 16:52:00 GMT donotreply@osnews.com (Morin) Comments http://osnews.com/thread?275235 http://osnews.com/thread?275235 http://www.jnode.org/node/1750
Included BeanShell and Rhino (JavaScript) as scripting languages (encouraging results with Jython, Kawa (Scheme), JRuby 1.0 and Scala)
(Have no idea why they list Scala with the "scripting languages" Scala though...

And before reverting to scripting languages, give Scala a spin. It far exceeds Java in power and flexibility. Sat, 29 Sep 2007 10:29:00 GMT donotreply@osnews.com (John Nilsson) Comments http://osnews.com/thread?275507 http://osnews.com/thread?275507 why is .net never flamed for speed issues??
