For the first time ever, we are doing a promo for a pre-release copy of the book. Amazon doesn't even have it yet, but Tara will be happy to answer questions.

She was kind enough to share a cover with us:

[Tara The Author]

Hi everyone. I'm excited to be here to promote my new book.

The dog ate my part of my table of contents so I'm just posting the beginning here.

java.lang.Void Hacks

Part I - Introduction
1 - What is java.lang.Void?
2 - What can I do with java.lang.Void? that I can't with void?
3 - What is the difference between Void in Java and C#?

Part II - Hacks
4 - Saving time with java.lang.Void
5 - Using java.lang.Void with Google

[Tara The Author]

As noted above, you can't yet buy this book at Amazon. But you can buy a preview copy at Google Checkout if your are using their new wireless network.

[Hussein Baghdadi]

Finally, will read this book ...

2 Questions:
1) A friend of mine claims, that c/c++ void is about 10 times faster than java-void.

Is it true?

It must be faster, because of the java overhead, but is '10 times faster' correct?
Will static Void improve speed?
Final Void?

2) How much memory do I need for a Void?
Is it clever to use a Void-Factory-Pattern, or to pool Voids for later use?
Or shall I go the opposite way and use lazy-Void-creation (perhaps, nobody needs a Void).

3) C++ has true Voidpointers.
I would like to cast some Objects (ResultSet for instance) to Void, send it via RMI to a different host, and cast it back to ResultSet (security by obscurity). Is it possible?
How would I do that?
Or shall I use VB?

Please answer by email, because I don't have time to visit this page again.

Will your book reveal the secret command line parameters that make all Java programs, no matter what age, use Void and run twice as fast??
If so, watch out, I know the industry has suppressed these so as to sell more expensive hardware so watch your back.

This is 9 questions, so I'll just pick the two most interesting ones

Sure. Just send it through a black hole. By the time you get it back it should be nice and unusable, err secure.

Or shall I use VB?

Gasp! No. You should use Ruby.

It was going to, but the dog ate that part. I didn't have a draft so it's lost forever.

[David O'Meara]

In the old days I stored my arguments as void pointers, then it was pointed that void has no meaning and hence my arguments had no point and I forget what I was going to say.

[Jeanne Boyarsky]

Dave: I had to read that three times so my head didn't explode. Then it was hilarious.

[Julio Cesar Damasceno]

It's a great book, the reading will be very nice.

Is it true that Bin Laden uses Void classes to hide ?
(BTW, this forum's number is weired )
