One 4K version of tetris on that page uses almost 40 MB of RAM after a few minutes

Did you consider that the memory you're seeing may be JVM overhead combined with pre-allocation? In smaller devices (like Cell Phones), the JVM is built into the device. So there's no real overhead for Java. The pre-allocation is also smaller to compensate for the smaller device. Considering that many of these devices have barely 64K available (never mind 120K), I'd say that Java fits just fine.

and after playing for a while there's occasional, noticeable pauses for garbage collection (yes, I verified it was from garbage collection)

I find it interesting that you singled out such an example without looking at many of the more interesting examples like T4XI, Robotron 4096, and Hunters 4K. Also, you may find Tetris 4K to be a much better version than the first item on the list.

Java's great for some tasks, it's almost like a cross-platform VB. But the language, or more likely the way the language is most commonly used, isn't optimal for some things. Games happen to be one of those things.

You don't know what you're talking about.

At one point I could have pointed to the poor performance and massive memory usage of VegaStrike. Does that mean that C/C++ is a "bad" langauge? NO! It means that it was poorly coded and still needed lots of work done. The developers worked on improving their codebase, and low-and-behold, the game got better. Perhaps it wasn't the language after all?

I use to maintain a
list, but it is very out of date now.

JET requires the JVM to be packeted to include Swing.

Uh, have you SEEN Java games that use OpenGL? It's a disgrace. I can't believe people like you bother to defend it.

I have, but apparently you haven't. Let me introduce you:

In my experience, C or C++ is faster across the board, regardless how piss-poor the coder is.

You mean, in your bias C or C++ is faster across the board. From your first paragraph, it seems obvious that you've never used any serious Java apps. OTOH, it may very well be the result of a new syndrome that's been forming. People don't know they're using Java! A perfect example of this is the #1 BitTorrent app, Azureus. It looks and works so good that no one questions what is under the hood!

SVG is a perfect format for interactive visualizations of dynamic data.

For example, here is an interactive genealogical data visualization that was produced using XSLT transformations and published as a RESTful service via a Java servlet. The sourceforge project has more information on how the visualization was produced.

Use SVG as a medium to visually repurpose data to create your own interpretation of the world!

If you want the interactivity, you should at least try an optimized pared down applet. It's true that most applets are slow, but it is frequently also true that they are written badly and/or contain heaps of additional libraries that they need to download. Use as much of java's built-in code as you can with the possible exception of the GUI library.

Look at lightweight graphical libraries like lwvcl (commercial) or thinlet (LGPL) for the controls. The zaval people even have a charting library for their lwvcl system. (I have never used the lwvcl library, it just looks cool - try their online demo. Thinlet packs amazing capabilities into a very small package.)

If you need to display 15 graphs at a time with limited interaction, then this may not be the way to go, but if you need to display one at a time with very rich interaction, this might be the ticket.

Some really cool GIS examples

there also exists one other FT plugin for giFT here

This always happens to me... When ever i do research on a topic (or am about too), it comes up in Ask Slashdot... must have a mental connection with Cliff... oh well

Anyway, here's what i've found (other than what's already been mentioned)

FuzzCat -- it seems to work, but A) it's more full featured than i'm looking for and B) i can't seem to find the source code for it... :(

HTML WYSIWYG Editor -- This is a good tutorial on how to write a formatting editor with javascript and IE4+. I think i'm going to use this (combined with some tricks used by Yahoo mail...)

Here r some others (from a german PHP list):

There is a security hole in slashdot. If you use IE4 or IE5, it is possible to get your password (you need to be authenticaded).
I submit a story about this hole 2 days ago. The hole is still there. Demonstration of this hole
Can somebody alert slashdot ?
If you use IE4 and IE5 you should better change your password.
Slashdot is not to blame, many web sites have this hole.

Hey! The reply #75 was N-O-T a joke ! If you click here you will see your password !!! Arrgh ! How does it work ?

just click here. If you use IE4 or IE5 you will see your password. (first you should be authenticaded on slashdot)

Some are more lethal than others

jigglypuff's information service

I am working in a distributed system to make any java-capable browser to act as a node. And it can take any kind of process. And everyone can add their process simply telneting to the server. I am sending my work to the Argentinian Congress of Computer science ( http://www.unp.edu.ar/cacic2000 ) if anyone are interested, and can read spanish, the paper, in PDF format is at HERE when i finish it i gonna install somewere and try to post it here in /.

try mycgiserver. They seem to be free.
