Last year, I took a trip to Asia. To stay in touch, I carried a GSM world phone, capable of receiving telephone calls in the countries I was visiting. The capability to receive calls with the same mobile phone number I use at home while halfway across the world seemed incredibly cool-at least until the first call came in! Mobile phones hide the location of the phone, which cuts both ways. A colleague had decided to call me in the middle of the day on a Friday, which had awakened me very early on Saturday morning, because the phone "hid"my faraway location from him.

It might seem like Hewlett-Packard can't decide to love or hate rival Sun Microsystems. Today, HP significantly broadened its certification for Sun's Solaris 10 operating system on its ProLiant rack and tower servers and BladeSystem blade servers. But on the other hand, HP has partnered with Transitive to jointly engage with Sun's customers to see how they might deploy that company's emulation technology. What HP loves, you see, is the money that some Sparc shops want to spend as they migrate to X64 iron.

Not so fast, Microsoft, Novell, and Oracle—Red Hat’s upcoming release of its enterprise Linux operating system will keep it on top for business use of Linux, an analyst said on Tuesday. The operating system version, dubbed RHEL5, is slated for March. The system’s advanced features and the company’s market entrenchment will ensure that Red Hat triumphs over its rivals, WR Hambrecht+Co analyst Robert Stimson said in a report. Mr. Stimson also predicted sales growth of 44 percent and earnings increases of 31 percent for the fiscal year ending February 28.

Last week we learned how to use iperf to measure network throughput, jitter, and datagram loss. Today we're going to learn more excellent ways to measure network performance using iperf and ntop, but first I have a couple of corrections to make.

Take advantage of QEDWiki, an emerging mash-up maker technology that provides Web users and developers with a single Web application framework for hosting and developing Web 2.0 applications.

This detailed, hands-on review examines Nokia's Linux-based N800 Internet Tablet first as a consumer electronics device, and then as a platform for open source software development. Reviewer Jerry Epplin infuses the review with crotchety humor and deeply technical insights.

Dave Freese has just released version 1.2 of Fldigi, a popular new program for Linux and FreeBSD which enables amateur radio operators to join their radios and their computers at the hip and create a new kind of ham shack: a digital ham shack. Here's the story behind both the rising popularity of "sound card" digital modes in amateur radio and how Fldigi lets you enjoy enjoy them on Linux.

Some years ago Linux creator Linux Torvalds famously compared changing operating systems to “performing brain surgery on yourself”. I’ve quoted him often because so many people seem to have unrealistic expectations when they pick up a Linux DVD or CD-ROM. I’ve recently received a couple of e-mails in response to my articles here on O’Reillynet that illustrate Linus’ point beautifully and demonstrate part of the problem Linux has faced in gaining greater acceptance on the desktop.

Following my recent article in which I wrote that neither I, nor several financial analysis firms, were aware of any companies that were planning to deploy Oracle's Unbreakable Linux, a handful of companies have told me that they are giving Unbreakable Linux a try. What I think is interesting is why they're giving it a try, and what it tells us about Oracle's intentions towards Red Hat.

There's little doubt that many e-commerce businesses embrace open source applications such as OS Commerce. The problem is that using open source software isn't for the faint of heart as you need a certain level of technical expertise to deploy and manage these applications. While you don't have to pay to use open source applications, providing the integration, implementation and maintenance for the servers hosting the "free" software can be costly and time-consuming.

I know that the original question was "Who are the top 5 OSS thought leaders", and that's been covered by several folks already. I'm going to ask a similar, but different question.

UNIX has a dialect all its own, and its vocabulary of commands is quite large. But you don't have to learn everything all at once. Here, discover more command-line combinations and expand your mastery of the UNIX language.

Commercial Linux distributor rPath, which has a variant of Linux and a build system for creating and deploying software appliances based on Linux, last week said that it has closed its second round of venture capital funding.

This article presents a little-known use of XUL (Mozilla's user-interface language) and shows how to take advantage of its superior performance and accessibility over HTML while maintaining cross-browser compatibility. I will illustrate this using a proof-of-concept JavaScript library that can render UI widgets using either XUL or DHTML. If possible, you will want to open this page in Firefox. The side-by-side examples below will not make much sense otherwise.

OpenVZ is a operating system level virtualization solution that lets you run several virtual servers on the same physical machine with very little overhead. EasyVZ is a GUI front end to OpenVZ that makes managing Virtual Private Servers very simple, easy and fun

Last October we had compared the performance of the open-source R300 display driver against the closed-source fglrx driver for ATI Radeon graphics cards. In that comparison a Mobility Radeon X300 was used with X.Org 7.1, but we have decided to take another look at this driver comparison under X.Org 7.2. In this last comparison, the fglrx binary blob had greatly outperformed the open-source driver. While the fglrx driver remains faster, has the performance delta between these two drivers decreased?

The Swedish Armed Forces has made the decision to migrate its servers from Windows NT to Red Hat Enterprise Linux. Following the deal, the Swedish Armed Forces will start replacing Windows NT with Red Hat Enterprise Linux across its core IT infrastructure.

Chelsio Communications Inc. has announced its standalone iSCSI Target 3.0 software, which enables enterprises to create high-performance IP (Internet Protocol) SANs (storage area networks) using their existing Linux server and storage hardware. The enterprise-ready Linux iSCSI (Internet SCSI) Target 3.0 is available for leading storage platforms, the company said last week.

Like the previously featured articles on new KDE 4 technologies for Job Processes or SVG Widgets, today we feature the shiny new multimedia technology Phonon. Phonon is designed to take some of the complications out of writing multimedia applications in KDE 4, and ensure that these applications will work on a multitude of platforms and sound architectures. Unfortunately, writing about a sound technology produces very few snazzy screenshots, so instead this week has a few more technical details. Read on for the details.

Many Linux apps let you manage your movie collection, or your book collection, or your music collection -- but Data Crow is one of the few that handles all of the above, plus software and images. It also puts a lot of import tools at your fingertips that can save you from entering information about your media manually -- including importing information directly from online services and text files, and extracting information from music files.
