Really nice. Great job guys. One of the things I miss from JQueryUI from ExtJS is the datasources which aren't (AFAIK) an integrated component of the framework. I'll give it a try.
Totally agree and this tool might help in this situations but still I find it more suitable to simply watch the memory usage, which in a sane application, should have a pattern.
Detecting memory leaks is easy: run some stress tests before deploying to production!
I mean, I don't see the use of this tool. Attach it to a live JVM to detect leaks which shouldn't be there?
Doesn't work in Ubuntu Maverick with X.Org 1.7.5
http://monocaffe.blogspot.com/2011/10/javas-ghost-jvms.html"how does tools like JPS, JConsole or VisualVM know the JVMs running in a system? They simply look in the folder /tmp/hsperfdata_foo where a 32KB data file with the PID as name is created for each JVM."
Not a hidden feature of Java, but of Sun's (Oracle) JVM which I'm not sure if happens in other JVMs but it's kind of useful for doing different stuff.
Because their RAM comes with a nice Apple logo and a sticker!
I didn't know that HN published every stupid story it got.
I'm working on making this a deployable WAR. In the future it should be able to be deployed in any AS and in google apps engine. But first, I wanted it to work as an applications server for JavaScript.
Jongo is a Java server (with embedded Jetty) which provides CRUD operations over any JDBC supported RDBMS using REST.

Here we work with scrum and have a pretty agile development cycle. I really believe that if we were to develop our site ground-up, we would use JEE again for the same reasons some of you've pointed out... and actually, we're doing it!
But, for example, many of our webpages are made with PHP using some CMS (Typo3) because it's perfect for this. Our mobile site uses our Java webservices from PHP too.
I've been working with JEE (formerly J2EE) and JSE for some ten years and I know of Java's (platform and language) problems, but I think that they are surpassed by its capabilities, tools, resources availability, etc.
Do I want Java to go away? Why I ask? It works! It's not perfect, is not shiny, is not "agile", but it gives management that warm feeling of cash flowing in. Oh! And it gives me a job!
I just have to raise my head to see at least 60 new HP computers and 100 23' HP monitors in my office. I don't see any of all this people using an iPad (most of us have one) to do work. So no, the PC market is not dead and it ain't going to be replaced by some 10 inch media player. Hell, I even have an iMac sitting idle next to me because I can't get it to work as I want to.
Not only on old phones, think about all those Chinese ripoffs of the iPhone, Nokia, etc... yeah! running J2ME!
Well, it's not a bad idea. Why let WebOS have the same faith BeOS (another Palm owned OS) be forgotten?
I've been an OO programmer for a long time and I really, really like the way functional programming works. It takes some time to re-think your previous assumptions, but even when in pure Java, a more functional approach provides a much better code.
And, maybe it's because I've used another languages that I find Scala pretty straight forward.
Groovy is pretty fast with Groovy++
To compare Linux with MacOS (or Windows) you should buy also a computer MADE to run Linux.
Please, go ahead and install MacOS (or Windows) in a bunch of HP Proliants or in a Sun Blade. How about in a Compaq nc6300? OK, you probably like better a Thinkpad X1. Maybe in your Netbook? How about in that old P3 you have at the basement collecting dust? Even better, why don't you install Lion on your old PPC iMac?
Well, I have Linux running in ALL of those computers and ALL of them work pretty much "out-of-the-box".
