Will EJB 3.0 turn J2EE thinking on its head?
Developers got their first view into what may be the future of Java development during last week's TheServerSide Java Symposium. What's in store for Enterprise Java Beans, in fact, may put some long-held Java thinking on its head -- literally.
Is Linux at the gates of the factory?
[ A Linux intro story for automation fans, with a few errors (most notably the author asserting that Linus patented Linux. :) ]
gumstix Introduces Smallest Commercially Available Linux Boards And Computers
The world's smallest commercially available Linux boards and computers were officially introduced today by gumstix, inc., a start-up that produces and sells high performance Single Board Computers (SBCs) and peripherals. Based on Intel's PXA255 processor with Xscale technology, gumstix tiny boards measure 20mm x 80mm x 8mm. At nearly half the price of and a third the size of competitors, gumstix enables software developers to create smaller and more price conscious embedded devices, applications and products for the growing Linux market
File alteration monitoring techniques under Linux
Most modern operating systems provide file monitoring facilities to give applications real-time information about changes to the filesystem. A variety of notification methods are used to tell the application when a change happens, ranging from an asynchronous signal being sent from the kernel through a user space tool printing the name of the changed file on its standard output. We'll take a look at some of the file monitoring facilities available to the Linux developer, starting with the lowest-level mechanism and working up to the highest.
On Scripting Languages
In recent years "scripting languages" are becoming a path which is a must go for rapid application development. The open source community has seen many scripting language implementations. Some really popular and good ones available are perl and python.
Using Shared Memory from PHP
IPC is one of the most important features of the UNIX systems. It allows two processes to communicate with each other. In this article we'll work with two System V IPC functions, semaphores and shared memory. System V IPC originated in SVR2, but has implementations by numerous vendors. It's also available in SVR4. This article introduces shared memory and synchronization (semaphores).
Black Duck Software launches open-source service
Start-up Black Duck Software next week will introduce two new products designed to help companies better manage their use of open-source...protexIP/Development software, a management tool for companies that develop with open-source software that allows managers to see which, if any, of their developers' software contributions contain open-source code, and provides an audit trail that tracks individual technical contributions.
KDE::Enterprise: Interview with International Hout
A new interview has appeared on the KDE::Enterprise website. In this interview Walter Stolk tells us why International Hout has chosen to use KDE within their organisation.
Implement Bayesian inference using PHP: Part 3
In this third article on Bayesian inference, Paul Meagher examines how to use PHP and Bayes methods to solve classification problems in medical diagnostic testing and Web survey analysis. Learn how Bayesian and conditional probability concepts are applicable to both building classifier systems and analyzing the accuracy of their output.
Implement Bayesian inference using PHP: Part 2
While the first article in this series discussed building intelligent Web applications through conditional probability, this Bayesian inference article examines how you can use Bayes methods to solve parameter estimation problems. Relevant concepts are explained in the context of Web survey analysis using PHP and JPGraph.
Penguin-powered push-to-talk comes to the rescue
As Linux PDAs and cell phones make their way into consumer and enterprise gadgets, an embedded version of the operating system has been developed for use as a public safety communications platform.
More Code Released to Open Source by Microsoft
Microsoft Corp's flirtation with open source has seen the company release C++ product code to the community for developers to pick-up and modify.
Seven open source business strategies for competitive advantage
Open source presents a large potential competitive advantage for hardware and software vendors, and vendors of complementary or substitute services. Linux has contributed greatly to the adoption and success of OSS. Companies such as IBM, HP, Red Hat, Oracle, and recently, Novell, have invested in, and legitimized the use of Linux for enterprise applications -- including datacenter operations.
