The Little Book of Semaphores is a free (in both senses of the word) textbook that introduces the principles of synchronization for concurrent programming.
In most computer science curricula, synchronization is a module in an Operating Systems class. OS textbooks present a standard set of problems with a standard set of solutions, but most students don't get a good understanding of the material or the ability to solve similar problems.
The approach of this book is to identify patterns that are useful for a variety of synchronization problems and then show how they can be assembled into solutions. After each problem, the book offers a hint before showing a solution, giving students a better chance of discovering solutions on their own.
The book covers the classical problems, including "Readers-writers", "Producer-consumer", and "Dining Philosophers". In addition, it collects a number of not-so-classical problems, some written by the author and some by other teachers and textbook writers. Readers are invited to create and submit new problems.

If you plan on getting a boxer dog as a pet, then you need to know about boxer dog behavior. Some people who first meet this breed think they are skittish but they would be wrong. Boxer dogs can be and usually are overly friendly. These dogs can become skittish if they are not greatly loved and shown love each and every day.

The i2010 strategy is the EU policy framework for the information society and media. It promotes the positive contribution that information and communication technologies (ICT) can make to the economy, society and personal quality of life. The European Commission presented it in June 2005 as the new initiative for the years up to 2010.
...and welcome to We Are What We do, a new movement inspiring people to use their everyday actions to change the world. We're not talking moving big mountains. More of a gentle nudge from the corner desk. A little prod from the sofa. A gentle push from the PE room.
So go on then! Track an action, share, connect.

EAI - The Broader Perspective
No one should have (or will) ever dared to build a 'Single System' which will take care of the entire business requirements of an enterprise. Instead, we build few (or many) systems,and each of them takes care of a set of functionalities in a single Line of Business (LOB). There is absolutely nothing wrong here, but the need of the hour is that these systems have to exchange information and interoperate in many new ways which have not been foreseen earlier. Business grows, enterprise boundaries expands and mergers and acquisition are all norms of the day. If IT cannot scale up with these volatile environments, the failure is not far.

ven though Web 2.0 and rich Internet applications (RIAs) are all the rage these days, building a rich Web front end for your stakeholders is not the answer when thick-client functionality is what you really need. I stated as much in my previous article, "Building a Java App Server Foundation for Thick-Client Deployment," which showed how to leverage a traditional Java Web server architecture to easily deploy thick clients.
Exception Handling with Spring and Log4J
How to log exceptions. This technique will log messages to your server log file, send an email, with the tag stack of the error, for error level warnings and display a generic page to the user.
First step is to set up Log4j.
Make sure you have the following classes in application lib or common server lib.
activation.jar
This can be got from http://java.sun.com/products/javabeans/jaf/downloads/index.html
Set up your log4J configuration file, put this file in your WEB-INF directory
This is the project page for SecondString, an open-source Java-based package of approximate string-matching techniques. This code was developed by researchers at Carnegie Mellon University from the Center for Automated Learning and Discovery, the Department of Statistics, and the Center for Computer and Communications Security.
SecondString is intended primarily for researchers in information integration and other scientists. It does or will include a range of string-matching methods from a variety of communities, including statistics, artificial intelligence, information retrieval, and databases. It also includes tools for systematically evaluating performance on test data. It is not designed for use on very large data sets.
This document is a guide to help troubleshoot problems that might arise with applications that are developed using the Sun Microsystems Inc. release of Java Platform, Standard Edition 6 (JDK 6 release or Java SE 6 release). In particular, this guide addresses possible problems between the applications and the Java HotSpot virtual machine. The document provides a description of the tools, command line options, and other help in analyzing a problem. The document also provides guidance on how to approach some general issues such as a crash, hang, or memory resource issues. Finally, the document provides direction for data collection and bug report preparation.
Technologist Clay Shirky argues that information overload isn't the problem tech journalism makes it out to be: it's really a failure of information filters. At the Web 2.0 Expo last week, Shirky said that the internet has made it easier and cheaper for publishers to broadcast information—so now the onus is on the consumer to filter out the noise (much like client-side spam filters). Hit the play button below to hear Shirky's well-argued points.

sux0r 2.0 is an extendable content management system (CMS) built around the principles of Naive Bayesian probabilistic content.
Naive Bayesian Categorization is the ouija board of mathematics. Known for being good at filtering junk mail, the Naive Bayesian algorithm can categorize anything so long as there are coherent reference texts to work from. For example, categorizing documents in relation to a vector of political manifestos, or religious holy books, make for a neat trick. More subjective magic 8-ball categories could be "good vs. bad" or company press releases in relation to stock market prices.
In addition to being a blog, RSS aggregator, bookmark repository, and photo publishing platform, sux0r 2.0 allows users to maintain multiple lists of Naive Bayesian categories. These category lists, called vectors, can be shared with other users. This allows a group of trusted friends to share, train, and use sux0r together.
This book is an introduction to Java™ language--a widely used programming language and a platform. It is meant to be both an introductory guide and a useful reference on Java and related technologies.

Dieses Netzwerk dient als Basis für das zweite Educamp auf deutschem Boden und gleichzeitig das erste internationale Educamp (10.-12.Okt.2008). Es ist die Nachfolgeveranstaltung des ersten EduCamp, welches vom 18. - 20. April 2008 an der Technischen Universität in Ilmenau in Thüringen (nahe Erfurt) stattfand. Hier versammelten sich Knowledge-Worker, Wissenschaftler, Entscheider, Agenturen und Studierende, die sich mit innovativen Formen, Formaten, Technologien, Strategien etc. des mediengestützten Lernens auseinandersetzen.
Es gab im Voraus bereits einige Ideen für das Programm, jedoch findet ein EduCamp nach dem BarCamp-Prinzip (Wiki-Link) statt, das heißt, die konkreten Sessions und Vorträge werden erst vor Ort festgelegt und jeder kann ein Thema mitbringen.
Hier z.B. ein konkreter Lesetipp: Jean-Pol Martin hat in der Wikversity einen lesenswerten Text veröffentlicht, der auch hier in den Foren schon diskutiert, auf dem EduCamp in zwei produktiven Sessions vertieft wurde und schließlich in die Planung gemeinsamer Zukunftsprojekte mündete: zum Text
We are reaching a point where the number of inputs we have as individuals is beginning to exceed what we are capable as humans of managing. The demands for our attention are becoming so great, and the problem so widespread, that it will cause people to crash and curtail these drains. Human attention does not obey Moore's Law.
