I don't quite understand this sentence, perhaps I'm not thinking
straight: "If a stone is hit, the speed vectors are devided by 2
(integer devision without fraction) as long as no stone is hit (which
can result in a speed vector of (0, 0))."

So, suppose when step 20 occurs:
* You're 2 pixels left of a stone.
* Your velocity-x will be 2 pixels/step on step 20 and (if possible)
21.
* velocity-y will be arbitrary.
What happens? Are you able to go partly through a stone?


MfG,
Tayssir

Terribly similar to ICFP 2003. No 1 or 3-day time constraint. What's the fun
in that?

the sentence before is important:

| the new coordinate does not hit a stone after adding the speed.

no, the robot is always stone-free. If you are 2 pixels left of a stone 
and your velocity-x is 2, the next turn you are 0 pixels left of a stone. 
Then adding the velocity will result in hitting a stone, so the new 
velocity is (1, velocity-y/2) and because this will result in a hit, too, 
again the velocity is devided, which will result in a velocity-x of 0 and 
velocity-y devided by 2 again.

I know this challenge (to the other readers: you can see it at 
http://www.dtek.chalmers.se/groups/icfpcontest/ ) and I liked the idea, 
this is one of the reason for this challenge. There might be many people 
who don't know the ICFP challenge, and I hope they'll have fun with it. 

One difference in my challenge is that you don't need to simulate fixed-
point arithmetic or complicated definitions of sin and cos. This helps to 
concentrate on a good algorithm.

Another difference is the time limit. For my challenge you have much time, 
so you can think and test a lot and perhaps there will be some interesting 
ideas or variations of the challenge submitted.

You might want to give proper credit then. Otherwise, some people might call
it plagiarism (sponsored by DrDobbs ?)

Please correct the typos in the spelling of "devided" and "devision". It 
should be "divided" and "division".

You have to keep reading the response until you get the amount of bytes
specified in the response's Content-length header. Here's a code
excerpt that does a POST and reads a response:

java.net.URL url = new java.net.URL(sURL) ;
java.net.URLConnection urlc = url.openConnection() ;
urlc.setDoInput(true) ;
urlc.setDoOutput(true) ;
urlc.setUseCaches(false) ;
urlc.setRequestProperty("Content-Type", "text/xml") ;
urlc.setRequestProperty("Content-Length", ""+sPostData.length()) ;
urlc.setRequestProperty("Connection", "close") ;

// ...write the POST data
java.io.OutputStream os = urlc.getOutputStream() ;
os.write(sPostData.getBytes()) ;
os.flush() ;

// ...read the response
java.io.InputStream is = urlc.getInputStream() ;
int nContentLength = urlc.getContentLength() ;
byte [] ab = new byte[nContentLength] ;

Clients of mine have occasionally brought in summer interns for rock 
bottom wages.  The pay was damn close to nothing.  On occasion, we have 
offered starbucks wages, because that was what we had left in the 
budget.  Even $16 an hour for a ten week gig only brings you to $6400 - 
chump change for industry, and sometimes what we have left to offer.

Will you get the best for this kind of money?  Sometimes, if the 
experience is good and the project interesting.  Other times, you need 
to offer real money to get good people.

These are essentially 10 week job interviews.  They do not pay that 
well, because we expect to burn a lot of our own developer hours keeping 
the interns busy, and looking over what they do.

That said, real negotiating starts somewhere near the end of the gig, if 
we want them back.  After all, the primary goal of a student must be to 
finish the degree and learn the material, not a summer job.  On exit, 
though, priorities change, and so does what we need to pay to get them.

Put the base directory of the classes on the classpath at compile-time using

You may simply use InputStream to read a text file inside a jar.
e.g. InputStream in = this.getClass().getResourcesAsStream("TextFileName");
I use this method to develop my j2me game.

Http protocol is a standard for all Java phones. However, most phones do 
not support "file" protocol.

The OP indicated that he wanted access files on the phone, not files in

Using temporary file is good because no hack is needed. We can't

there is not enough wires, to cover all his options , unless he implements 
some external logic.

he has  a number of options.

1. give up
2. use the parallel port.
3. use the usb port with a couple of extra chips.
4. if he insists on using the serial port, he just needs a parallel to serial 
convertor chip.
then  feed his signals into  the parallel side.
he can use the  chip to handle the RS232 interface  

 Then use 2 other control lines 1 to reset the chip & 1 to act as a clock. ( 
unless the chip implements it own internal clock)

 first step , each time he wants to read.
1. issue a reset  signal to the external chip ( puts the parallel chip in 
exactly a known state)
2. issue a clock signal to clock the data out, until 1 byte received.
allow the api to assemble the byte.
3. read byte , decode bits.
go to 1.

he  does not even need  a voltage convertor. to get his +- supply. if he is 
smart he can leach off the RS232 port. ( set 1 line high , & 1 line low then 
use that to power the chip & circuit ( cmos))

Iam using a simple webpage to view/download excel files. But for some

up garbled. I tried altering the content type and also did some tweaks
but nothing works... Any pointers in this regards ??

Iam using a Apache Tomcat server.

This is the script itself:

From: Mike <[EMAIL PROTECTED]> 

Hey!

I'm new to Java and want to try to do things properly, so would be
grateful for guidance on the following.

I have a HashSet of fairly complicated objects, and don't want to
instantiate a new one to use the "contains" method to see if the object
exists in the HashSet. Nonetheless, I need to find out if the nascent
object is in the Set (specifically, if I did create a new instance, would
it be the same as one already there).

So, my question is:

1. Is there an idiomatic way to do this, or
2. Has the entire fleet left with me standing on the dock?

Many thanks.

Regards,

Mike

fOwner is of type private static DatabaseManagerSwing. I use this to 
make it a class var and visible to all of the methods in the class 
FontDialogSwing. Just happens that type DatabaseManagerSwing is the 
calling class name. I did not make this a model dialog. I then
can get/set attributes of the calling class objects.

This is not the standard way of way of coding it but it fit what I 
wanted  do.  This is so I have a reference to all of the object of type 
DatabaseManagerSwing. Thats why you see references to it later in the code.

The important thing is that it has all the objects you need to build 
your own dialog, the way you want


Thanks in Advance...
IchBin
