Doesn't Parallels require administrator rights on Windows and root on Linux to use? If so, doesn't that restrict how easily you can use this solution on a arbitrary Windows machine?
VMWare - has a free player - has all sorts of high-end features - has a reasonably extensive library of ready-to-run "virtual appliances"
Parallels - has a cheaper base version ($50) - has a simpler user interface
If I was managing a lot of servers, I would want to get VMWare. See the cool demos on their site, where they migrate a running VM from one box to another.
I don't need to do that. I just want to keep around a bunch of Windows, Linux, and Solaris images to make sure my applications really do run anywhere. Parallels is great for that.
This must be targeted completely at office environments. Why else would it use Windows CE and RDP. RFB(VNC) is at least 10 times as common for home use. Lack of RFB support out of the box is a puzzling flaw.
Of course, RDP and RFB are both available under Linux and Windows CE.
That seems roughly accurate, although I'm not so sure the.NET equivalent of bytecodes retain as much information as their Java counterparts. This is really a function of implementation and not language. Compiled Java (like GCJ and its commercial predecessors) has been available for years. Running C in a VM isn't commonly done either, but is definitely possible. I'm sure you realize this, I just didn't want people to be mislead by your post.

Almost. The Smalltalk version (SUnit) was the original which inspired JUnit. It wasn't the watershed that JUnit was due to the relative popularity of the languages.
Actually, latency is the big problem--not bandwidth. Technologies that address latency problem are now becoming available. Check out Sun Ray, NX, and THINC.
The second case actually works for my position Engaging in any act in order to solicit attention from strangers suggests serious psychological problems, not the least of which is self worth!
So everybody in showbiz (or school plays for that matter) has serious psychological problems if they're doing it "in order to solicit attention from strangers"? Thank goodness I spend so much time reading slashdot. I always thought I was an introvert, but now I know better.
What I can do in 200 lines of COBOL to run through and process business data would take 2000 in Java or C++
I worked for 4 years as a COBOL programmer before gladly moving to Java (with PowerBuilder and VB along the way). I've now been a Java programmer for longer than that, so I'm technically a "crazy gray-haired coot" around here. If you can accomplish the same amount in 200 lines of COBOL and 2000 lines of Java, you should definitely stick to COBOL. It will be best for all concerned.
Sorry, that was way out of line. You're right that the effectiveness of the language depends enormously on what type of program you are writing. I just can't think of any programs that would take twice as many lines to write in Java, let alone ten times. Personally, I found that with a lot of experience and effort, I could make COBOL about half as productive as Pascal.
BTW, modern COBOL does support local variables through the use of subprograms. Most COBOL shops frown on the use of language features introduced after the early 1970's, however. Many even have standards against it. No, really.
Sphinx is a speaker-independent large vocabulary continuous speech recognizer under Berkeley's style license. It is also a collection of open source tools and resources that allows researchers and developers to build speech recognition system.
FreeTTS is a speech synthesizer written entirely in the Java programming language.
Given the size of the drive(s) in the average TiVo, it would make more sense to keep a local copy and rsync it periodically. The entire database is only a gig.
Exactly. The funny thing is that Sun R&D already has research versions of WAN Ray's, software only SunRays, and the SunRay Server running on Linux. Since they have not only developed these things, but leaked them to the general public (and quite some time ago at that), I bet R&D already has prototypes of CD burners, webcams, etc... After all, current SunRays have USB. There is no reason why they couldn't move forward on this.
It is very puzzling. Sun is smart enough to see the promise in this technology, but they don't want to release the pieces that would really drive it. It seems like they fear making the SunRay a well supported open platform for fear of making it a commodity and cutting into their profit margins and sales of their other products. By keeping the platform closed, however, they are just encouraging buyers to go elsewhere.
NX is rapidly adding the features of SunRay and not stopping there. Soon there will be cheap thin-clients that support NX. If Sun doesn't start acting soon, in a few years, NX will be what SunRay could and should have been.
I'm a big fan of both Sun and Java, but it dismays me that they continue to push web services and try to make better tools and APIs for web services without making their sites accessible to web services. Why oh, why, can't they at least provide a nice web service for Bug Parade.

Do you have any opinions about something more analogous to a library card or a security key? I guess I'm thinking about something like SunRays for the home, although the idea is obviously more of a vague notion, right now.
Unintentionally retained objects can be quite hard to trace and understand in Java. Better tools are definitely needed. I feel yor pain.
I can't tell the JVM when I'm done with an object, so I have to give it hints, or arrange it so my backlog of garbage doesn't get so big, or simply avoid allocation altogether.
What do you mean hints? If there are no references to an object, it is eligible for GC. If there are references to an object, it can't be GC'd. What sort of hint do you mean? If you could dispose of an object explicitly, (and consequently without necessarily eliminating all references to it) the language wouldn't be garbage collected.
When you say "I'm not complaining about the implementation so much as the architecture." are you suggesting GC'd languages make programming harder? If so, let me suggest that the real problem is that Java doesn't have adequate tools for detecting accidentally retained objects.
Not to be a pedant, but I doubt either of these were GC bugs.
Your description is a bit too vague, for me to guess with much certainty. I bet you had some finalize methods that were preventing the GC thread from reclaiming your objects fast enough. This situation should be easier to diagnose and prevent than Sun currently makes it, but it isn't really a GC bug. Effective Java has a nice write-up on this problem. If you really think it is a GC bug, try creating a simple test case that demonstrates it. Java has plenty of bugs, but in my experience, trying to construct a simple test case for submission to Bug Parade will often demonstrate that you didn't really understand the problem.
This sounds quite a bit like either this bug, or a close cousin. It is quite nasty, but really a bug in the java.lang.String code, and not in the GC.
I would like to learn more about the advantages of the WPS to the desktop user. Do you have any references (preferrably free and on-line) that would tell me more?
I pity anyone who has to use 1.3.x because of all the great new stuff in 1.4.x. It is hard to live without exception chaining, for example, once you have lived with it. The biggest issue mentioned in the memo is the memory footprint of multiple JVMs. It isn't scheduled to really be addressed until Tiger.

That is all good solid advice, but currently way beyond anyone new to Swing. I really hope that JSR-296 will make this the easiest path to follow.
