Qnx 6 don't have any problems running Quake3 on my VooDoo3 card. (But only VooDoo3 is supported for 3d right now). Why should that require a driver in the kernel?
Well thatone is easy. On an amiga 500 the movement of the mouse cursor is actuelly timed to the screen update frequence, meaning that the mouse updates EXATLY once each vblank. The result is that when you move the mouse in a constant speed, the cursor also move in a constant speed. Something that no other hardware is able to do -(( (Yes, there are plenty things the new computers can do the old can't so I would not say the amiga 500 is better then the currently available computers)
Curse Intel and Apple for that #*&*$&*#$& usb mouse standart
But why use arrays at all? If you use a better container-type that grow when you add elements and shrink when you take the out you are almost there. And then insted of using any kind of subscription to name the elements, use an iterator. That way it is really diffucult to go to far in the array.
(A reply to myself) I actuelly tried to run the benchmark Synchronized took 213 ms Unsynchronized took 22 ms
So you can conclude that calling a synchronized function is 10 times as slow, as calling one that is NOT syncrhonized. But this does NOT matter because the actuell time it take to call a synchronized method is so small. It calls the synchronized method 10000000 times in ~200 meaning that you can call a synchronized method 50000 times each ms(If you already got the lock)
So in any real program the work done in the function would far outweight the small extra time it take to call a method.
Now I just wish they would make all the swing methods synchronized so swing would be thread safe:-}
Interesting. A text that say that some things in java are not as slow as people belive, and yet it fail to deliver any prove anything. For ekample it say: synchronized methods are not slow, and yet it include no benchmark/test to backup that claim.
And about the strings example: If you want't to prove that the Immutable string class is not slow the right way to do it is to make a program that make a lot of string operations and then compare the speed with one of the non Immutable string classes for java that exists.
I really wish that the slashdot editors would read the stories and dismiss the one widtout any information.
(Yes I know, the slashcode is free, so I could just make my own news-site but life is to short, and the studie take to much time.
Then how do I add 2 Integer objects together? The only solution I found was to get the int value of both objects, add theese together and then use the result to create a new Integer object. While this DOES work, it seems to be a bit to much work.
As far as I remmeber what is odd with Vector is that it might use bit's to store the bool values. (You might belive that Vector store bool objects as an array of bools but it don't. Am I right?
But the problem is that after someone install a update which cause their workstation to lose all network support it become very hard to tell him he still needs to install all updates.
There are days where I think an unpatched windows, and a firewall that refuse all ingoing connections are the most stable(Least downtime) solution.
Why should the fact that the music was sold online change the number of sales? Any cd that is going to sell > 100.000 can be found on kazare/gnutella/whatever share the day after it is published so music piracy will not be worse. You could argue that the fact that the music was sold online would reduce the number of sold units because of "lag of exposure" but on the other hand, selling to half the price might increase the sale, and even if they only sell 1/5 the number online they would still make a good deal.

The point is that if the application crash the automatic watchdog(Part of the High available toolkit) wil just restart it and continue.
It is listen as an apache project at www.apache.org
The point MIGHT be that php is part of apache. Remember Apache is far more then just a webserver. Just have a look at php.apache.org
The problem is not acceleretion but timing. It is the same of problem you get if you try to play a movie with 25 frames/second on a 85 Hz display.
Well last time i checked, an amiga 500 updated the screen at 50/60 Hz(Depending on your location)
(Unless you used interlace ofcause)

Well, he has not been proven wrong yet.

Oh, sorry forget that. It is
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)
on redhat linux 7.3
Well but as far as I could see only for the synchronized example. It would be far more interesting to se some benchmark on the String class.
(A reply to myself)

Synchronized took 213 ms
Unsynchronized took 22 ms

>No, sorting faster than O(N log N) is not possible.
Sorting faster then O(N log N) is posible. What is NOT posible is sorting faster then O(N log N) while ONLY using the > operation to order elements.
If you make a program that generate N random numbers between 0 and 56000 sorting them in O(N) will be simple.
They do? What kind of tape is that? (Yes I am curious. Each time I compare tape with hd, I find that hd is cheeper then tape)
You can't blame the site just because MSIE is unable to scale fonts contained widthin a style-sheet. That is a problem with MSIE not the site.
Nope, that is something the movie got total wrong. You should read the book insted :}
But with zero revenue deductions are not that usefull.

The problem is that the cpu-bus is only 167Mhz, so even DDR266 ram is faster then what the cpu bus can handle.
To make things worse this bus is SHARED between the 2 processors, making the processors really starve for memory bandwidth.
And me: I just hope that IBM soon release the 970 chip, because MacOSX might be nice, but the hardware is to slow for me.
But the problem is that after someone install a update which cause their workstation to lose all network support it become very hard to tell him he still needs to install all updates.
There are days where I think an unpatched windows, and a firewall that refuse all ingoing connections are the most stable(Least downtime) solution.
Java feels slow(ie: is slow) begause swing is S L O W. .net is calling directly to the windows gui and thus should apear much faster.

Yeps, just run your software as nobody
