fwknop stands for "Firewall Knock Operator" and is an upcoming piece of software that will be released at the DEFCON 12 conference in July, 2004 in Las Vegas.
fwknop implements network access controls (via iptables) based on a flexible port knocking mini-language, but with a twist it combines port knocking and passive operating system fingerprinting to make it possible to do things like only allow, say, Linux-2.4/2.6 systems to connect to your SSH daemon.
fwknop supports shared, multi-protocol port knock sequences along with both relative and absolute timeouts, and coded port knock sequences encrypted with the Rijndael block cipher.

％ Train a two layer neural network with the Levenberg-Marquardt
％ method.

％ be trained.
％
％ Given a set of corresponding input-output pairs and an initial

％ trains the network with the Levenberg-Marquardt method.
％
％ The activation functions can be either linear or tanh. The
％ network architecture is defined by the matrix NetDef which
％ has two rows. The first row specifies the hidden layer and the
％ second row specifies the output layer.

A heap is a binary tree satisfying the following
conditions:
This tree is completely balanced.
If the height of this binary tree is h, then leaves
can be at level h or level h-1.
All leaves at level h are as far to the left as
possible.
The data associated with all descendants of a
node are smaller than the datum associated
with this node.

In this article, I will explain how to create UDP packets and then send them to a remote server through the Internet using WinPCap for Windows. The code has been tested to work with Windows XP SP2 and Vista SP1 on Linksys routers, and on Toshiba modems connected directly to the Internet. Please note that the code here is very minimalistic, and can be greatly expanded depending on your needs. The reason I use WinPCap in this article is that it solves the issue of Winsock for Windows (XP SP2 and above) not allowing raw UDP packets to be sent (in Linux, you can just use regular sockets). With WinPcap, it is possible to specify your own source IP and source hardware addresses in packets.

cordic methods describe essentially the same algorithm that with suitably chosen inputs can be used to calculate a whole range of scientific functions including sin, cos, tan, arctan, arcsin, arccos, sinh, cosh, tanh, arctanh, log, exp, square root and even multiply and divide.
the method dates back to volder [1959], and due to its versatility and compactness, it made possible the microcoding of the hp35 pocket scientific calculator in 1972.
here is some code to illustrate the techniques. ive split the methods into three parts linear, circular and hyperbolic. in the hp35 microcode these would be unified into one function (for space reasons). because the linear mode can perform multiply and divide, you only need add/subtract and shift to complete the implementation.
you can select in the code whether to do the multiples and divides also by cordic means. other multiplies and divides are all powers of 2 (these dont count). to eliminate these too, would involve ieee hackery.

Genetic Algorithm example using Java
You have 10 cards numbered 1 to 10.
You have to divide them into 2 piles so that:
The sum of the first pile is as close as possible to 36 and the product of all in second pile is as close as poss to 360.

Modern C++ Design is an important book. Fundamentally, it demonstrates generic
patterns or pattern templates as a powerful new way of creating extensible designs in
C++--a new way to combine templates and patterns that you may never have dreamt was
possible, but is. If your work involves C++ design and coding, you should read this book.
