So, the JVM allocation works, and there's no performance bottleneck there. But where is it? Why is Java still so painfully slow?
Java used anywhere, from webservers to full client apps just feels and even *looks* slow! Stop coming up with pointless articles. Find the problem and fix it.
>Just goes to show that even if you have a great technical product you'll still need the marketdriods. Unfortunately.
Java is slow. I don't care what part of the JVM sucks, it just sucks. Even marketdroids wouldn't be able to do anything about it. The current JVM being faster than what was available 5 years ago doesn't make it a great technical product. It still sucks, just a little bit less than it used to.
There are no batteries, they are using passive RFID tags...
In most systems similar to this, when the power is out, all doors are unlocked. This is not intended for your house's front door, it is mostly for offices, public service buildings, etc. And not necessarily the front door, but most likely inter-offices door, different department/areas access, etc...
Sensible areas probably aren't targeted by the research, although I fail to see why any kind of serious "research" is needed here? It's a bloodily obvious use of RFID tags... The article is lacking a lot on details though, maybe there's more to this "research" not mentioned in the hundred words or so text?...

Call me old fashioned, but I for one am _not_ baffled by the vast regions of "vague space" that my file systems offer me.
Same thing here. The hard disk is the physical place where my files reside. Simple enough.
Then, when I click File-Open in Word, the little man inside my computer takes the bus on Data Road to go get my report.doc file. I get it, no problem with that.
But before buying tickets, he checks in its drawer, and if a small part of the file happens to be there, he hands it to me before getting on the bus and bringing me back the whole thing. Efficient and fast, I get that.
But, the files aren't always accessible by bus. Sometimes, the little man has to ask his daughter Ether to get on her bike and go fetch my report.doc from the neighborhood. But she's been warned : she can't take the road until there's no more car in sight. If she ever get slammed on her way back, she must drop everything, get back to the little man's house and try again. I know, it's weird, but that's the way it works.
Thanks to my company's 3 hours intensive training, I know the ins and outs of my computer. I don't need no stinkin' abstraction. Let's deal with the real things.
A former Parker Brothers employee says this about the game: "You spent a lot of time roaming through similar-looking screens, and then the damn Nazgul would jump out and you'd run around like crazy. I forget most of the details. It was a competent but not stellar game I think."
Sure sounds dull... Not stellar? I hope this former employee isn't a developer. Last time a programmer told me his code was "competent but not stellar"... ouch!

GTK-- vs. QT

Being cross-platform is a major selling point for commerical Qt users, however, so if you need your apps to work on Windows then it's clearly the way to go.
Absolutely.
One important thing to note about Qt is the fact that it ain't a wrapper around existing GUI APIs. It emulates the different GUIs out there, so it does the drawing itself, avoiding going through some additional API layers. That translates into a fast and responsive GUI.
I tried it on both Windows and Linux using the platform's native GUI and GUIs from other platforms, i.e. the Motif or CDE style on Windows, the Windows style on Linux. It is very convincing and very fast.
When performance matters, I definitely go with Qt.
Watch out for that "non-commercial" license on Windows though. It might not be appropriate for what you are doing. Your company will probably have to acquire a Qt license for Windows.
Just for your info, it is a problem with babelfish. It doesn't know how to translate "happenin" without the 'g'. Try it with "What is happening?", you'll get "Que se produit?" (which doesn't really make sense...) and it'll translate back to "What occurs?" (which is a lot closer to the french sentence than "What is happening?").
And now, "slash dot" gives "point de barre de fraction" (believe me, this is silly) and "not bar of fraction" back to english.
Now I understand why everybody hates it when there's a french article posted on Slashdot...

Sure. I also ran a test last year doing simple arithmetic comparisons between Java and C++.
Guess what, C++ won. There goes your argument.
Nevermind the fact that what you did is compare one JVM to one compiler generated binary...

I've seen the controllers, they replaced A, B and C buttons with CTRL, ALT and DELETE.
