Go read Joe S. production notes on how fricken hard it was to get Babylon-5 made. It boils down to keeping people's attention and building viewership.

Another problem is that TV tends to fall into easy to understand story / plots. Think of the Wander-who-does-good-deeds. Touch by an Angle and Knight Rider where identical shows in this respect. You must have your heroes and villains identifiable by their archetypes so anybody with in the first 5 minutes of watching a show can figure out who everyone is and where they stand.

Then there is the Deus ex machina problem. Every show must be neatly tied up at the end of the 43 minutes; and too often technobable is the rescue.

Finally, it's damn expensive and not a sure sell.

No, he can't... he's limited to 500 characters.

Since when did Google and Microsoft agree on the definition of "open"? Good luck!

I never understood why microbenchmarks are run with bad algorithms. If performance was critical, I would not write the code the way it has been written above. Also, for Java, in performance critical situations, you should run the test multiple times to see how the JIT compilation affects the performance.

Here is the code I would write for this. It works equally well in Java, C or C++.

public class Chain
{
protected static final String versionID = "@(#) $ Id: $ ";

private int size;

public Chain(int size)
{
this.size = size;
}

public int kill(int nth)
{
int[] people = new int[size];
for(int i=0;i 1)
{
curCount++;
if (curCount % nth != 0)
{
people[fillPos] = people[curPos];
fillPos++;
}
curPos++;
if (curPos == realSize)
{
realSize -= (curPos - fillPos);
curPos = 0;
fillPos = 0;
}
}
return people[0];
}

public static void main(String[] args)
{
int ITER = 100000;
runTest(ITER);
runTest(ITER);
runTest(ITER);
runTest(ITER);
}

private static void runTest(int ITER)
{
long start = System.nanoTime();
for (int i = 0 ; i ITER ; i++)
{
Chain chain = new Chain(40);
chain.kill(3);
}
long end = System.nanoTime();
System.out.println("Time per iteration = " + ((end - start) / (ITER )) + " nanoseconds.");
}

}

sorry, I'd forgotten how slow mod operator is. Even faster:

public class Chain
{
private int size;

public Chain(int size)
{
this.size = size;
}

public int kill(int nth)
{
int[] people = new int[size];
for(int i=0;i 1)
{
curCount++;
if (curCount != nth)
{
people[fillPos] = people[curPos];
fillPos++;
}
else curCount = 0;
curPos++;
if (curPos == realSize)
{
realSize -= (curPos - fillPos);
curPos = 0;
fillPos = 0;
}
}
return people[0];
}

public static void main(String[] args)
{
int ITER = 100000;
runTest(ITER);
runTest(ITER);
runTest(ITER);
runTest(ITER);
}

private static void runTest(int ITER)
{
long start = System.nanoTime();
for (int i = 0 ; i ITER ; i++)
{
Chain chain = new Chain(40);
chain.kill(3);
}
long end = System.nanoTime();
System.out.println("Time per iteration = " + ((end - start) / (ITER )) + " nanoseconds.");
}

}

Re: Introduce Your Rogers HTC Android Phone!

Johan — Sat, 13 Jun 2009 23:39:06 -0000

Is anyone running an ADP1?

If I buy one direct from Google (and my interest is in developing applications so an unlocked and rooted phone that I can switch firmware on would be handy for testing) what are my chances of convincing Rogers to let me use it on their network at some not unreasonable expense?

Any tips on negotiating with the local GSM monopoly when you are bringing your own phone to the table?
