How the K-mean Cluster work Step 1. Begin with a decision the value of k = number of clusters Step 2. Put any initial partition that classifies the data into k clusters. You may assign the training samples randomly, or systematically as the following: Take the first k training sample as single-element clusters Assign each of the remaining (N-k) training sample to the cluster with the nearest centroid. After each assignment, recomputed the centroid of the gaining cluster. Step 3 . Take each sample in sequence and compute its distance from the centroid of each of the clusters. If a sample is not Currently in the cluster with the closest centroid, switch this sample to that cluster and update the centroid of the cluster gaining the new sample and the cluster losing the sample. Step 4 . Repeat step 3 until convergence is achieved, that is until a pass through the training sample causes no new assignments.

The market for miniature computer programming is exploding. C++ Footprint and Performance Optimization supplies programmers the knowledge they need to write code for the increasing number of hand-held devices, wearable computers, and intelligent appliances. This book gives readers valuable knowledge and programming techniques that are not Currently part of traditional programming training. In the world of C++ programming, all other things being equal, programs that are smaller and faster are better. C++ Footprint and Performance Optimization contains case studies and sample code to give readers concrete examples and proven solutions to problems that don t have cut and paste solutions.

ExcpHook is an open source (see license.txt) Exception Monitor for Windows made by Gynvael Coldwind (of Team Vexillium). t uses a ring0 driver to hook KiExceptionDispatch procedure to detect the exceptions, and then shows information about the exception on stdout (using the ring3 part of the program ofc). The difference between this method, and the standard debug API method it that this method monitores all of XP processes, and the program does not have to attach to any other process to monitor it, hence it s harder to detect. The code Currently is considered as ALPHA, and it has been reported to BSoD sometimes (on multi core/cpu machines). Take Care!

// This Communications Component is implemented using separate Read and Write // threads. Messages from the threads are posted to the Comm control which is // an invisible window. To handle data from the comm port, simply // attach a handler to OnReceiveData . There is no need to free the memory // buffer passed to this handler. If TAPI is used to open the comm port, some // changes to this component are needed ( StartComm Currently opens the comm // port). The OnRequestHangup event is included to assist this. // // David Wann // Stamina Software // 28/02/96 // davidwann@hunterlink.net.au
