BusinessWeek's Steve Hamm and Geri Smith have written One Laptop Meets Big Business, a good article summing up the recent history of the OLPC project and it's difficulties with sales numbers, fading promises, Intel, and its internal strife over the Microsoft decision. None of that information is particularly new, but the article continues and goes in to some insightful problems with the educational model of the OLPC project formulated at 1CC, the OLPC headquarters; namely, hubris.

A couple of weeks back, a small New Zealand-based company, OnlineGroups.Net, released the source code for its online collaboration platform, GroupServer. When a big company releases source code for anything, it's often termed a risky move. For a small company, the risks are more or less the same.

The popular social networking site Facebook just announced a Chinese version, but similar Chinese-based Web sites such as Xiaonei and Hainei have been struggling there. However, since April, UCenter Home, an open source social network service based on PHP and MySQL, is pushing open social networking in China. Like other successful follow-the-leader Web sites in China (take Baidu, for example, which is a counterpart of Google), UCenter Home lacks innovative ideas but is good at localization. Its social network framework copies Facebook's, but it brings a style to the Chinese market that is more welcomed by local people than other foreign and domestic competitors.

Well, since I've gone through both Ubuntu and openSuSE Linux, and my curiosity about Unix systems in general has really started to kick in, I've decided to go through a few more variants to see what they are like, how they load on my laptops, and whether I might prefer one of them over my current favorite (Ubuntu). I might end up regretting this decision, but I assume there will be plenty of adventure and frustration along the way, and perhaps some learning and enlightenment.

LinuX-Gamers Live is a live DVD from Germany based on Arch Linux that includes nothing but games. Version 0.9.3 was released in June and provides an excellent means of sampling Linux games or setting up a home arcade, although a few of the games wouldn't run on my machine. There are no productivity tools, Web browsers, or package managers here; this disc is all play and no work. Because it's a live DVD, no hard drive is required to run the games. Once you burn the downloaded image to a DVD, you have a portable arcade that will run on any x86 system with 512MB or more of RAM. A 3-D accelerated video card is also required for most of the games. Proprietary drivers for Nvidia and ATI-based video cards are included, so you can enable acceleration for those types of cards by simply answering a few dialogs during the boot process.

A private school in St. Louis, Mo. is increasingly choosing Linux for the computers it supplies to students and faculty, according to laptop supplier Lenovo. Students at the Whitfield School are using Linux about 86 percent of the time now, Lenovo says, up from 50 percent three years ago. Lenovo has supplied about 600 laptops to the Whitfield School, it says, including systems that run both Linux and Windows. Whitfield started its PC program in 2005, and this year achieved its goal of supplying each student in grades six through 12 with their own laptop, it says.

Today's IT managers face tough choices. PCs that run fine today have an uncertain upgrade path, now that Microsoft has chosen to discontinue Windows XP. Upgrade costs associated with Vista, coupled with the ever-escalating cost of application licenses, make switching to desktop Linux an increasingly attractive option. For many businesses, however, it's difficult to know where to begin. The Linux market is broad and thriving, with myriad options to choose from. Most organizations will want to phase in Linux gradually, which in many cases will mean supporting a heterogeneous computing environment for the first time. As a result, it can be hard to predict where software incompatibilities might affect critical business processes.

Linux is a hacker’s dream computer operating system. It supports tons of tools and utilities for cracking passwords, scanning network vulnerabilities, and detecting possible intrusions. I have here a collection of 10 of the best hacking and security software tools for Linux. Please always keep in mind that these tools are not meant to harm, but to protect.

A controlled dial-on-demand router is a convenient tool. An uncontrolled dial-on-demand router is not. The Wireshark network protocol analyzer helped me track down the cause of some strange and unwanted dialup connections. Wireshark is a 20MB download. The GPL-licensed utility runs under Linux, Unix, Mac OS X, and Windows. The problems I needed to solve were all with a Windows client. My SMC Barricade 7004AWBR wireless router has an RS-232 port and can control an external modem, which I use for Internet connectivity. While there is quite a bit of Ethernet traffic on my network between several Windows machines and a Linux server, only a small portion of the traffic is addressed to the gateway, calling for an outside connection. Connections are made automatically if required, and if the connection is idle for a specified interval, the router quietly drops the connection and waits for later requests to dial out again.

Venture funding for open-source companies rose to $115 million in the second quarter, a 14 percent increase over the same period a year ago, according to The 451 Group. And funding for the first half of the year is up 62 percent over the first half of 2007. That's all the good news. The bad news is that seed and series A funding remains anemic and may continue to remain so while venture-backed companies struggle generally to find a public exit, i.e. an initial public offering. In the second quarter, there were exactly zero IPOs for venture-backed companies--whether they were open source or otherwise.

There's something strange going on. As Bill Gates steps down from active involvement in the day-to-day running of Microsoft, there's a natural tendency to speak about the “end of an era”. That's certainly true enough, but people are going beyond this factual statement to indulge in some serious revisionism.

Microsoft Corp. today unveiled projects to improve data portability between Office 2007 and other document file formats, including the design of a new translator for exchanging OOXML (Office Open XML) and HTML documents. The company also posted the 1.0 version of technical documentation for protocols in Office and other software that enable those applications to interact with third-party programs.

Apple's OS X, which has been an official certified Unix system for some time now, is often installed onto Internet-exposed or intranet-only Web servers for serving up dynamic content. I've worked with such configurations for a couple of years, and with GNU/Linux alternatives for even longer. There are at least three reasons why GNU/Linux systems do the job better. Web servers are key corporate assets, and systems administrators are supposed to keep them humming along, but that's not always easy. Security is always an issue for sites, as shown by daily vulnerability reports and security advisories. Performance, in terms of load time and response time, is another key issue. Customers get frustrated if it takes longer to add something to their browser's shopping cart than it would take them to visit a nonvirtual shop to buy it there. Sysadmins also must focus on availability. If your site is down, you'll lose all the benefits an otherwise well-administrated Web site provides.

Bonnie++ allows you to benchmark how your filesystems perform various tasks, which makes it a valuable tool when you are making changes to how your RAID is set up, how your filesystems are created, or how your network filesystems perform. Bonnie++ is available for openSUSE 10.3 as a 1-Click, for Ubuntu Hardy, and in the standard Fedora 9 repositories. I installed Bonnie++ from the 64-bit Fedora 9 repositories. The packages for Ubuntu and Fedora both install Bonnie++ into /usr/sbin, while openSUSE installs into /usr/bin. Bonnie++ will complain and fail to work if invoked as the root user, but if Bonnie++ is installed into /usr/sbin instead of /usr/bin, to invoke Bonnie++ as a regular user you will probably have to include its full path.

Firefox 3 has been out for two weeks now, so get with the program: It's time to hack it. The newest version of Mozilla's browser has plenty of new features, including the site identification button, the Bookmarks Library and what has become known as the "Awesome Bar" -- and I'll show you how to hack them all. You can also force the browser to use Gmail for mailto: links, discover a hidden "Easter egg" and more. So fire up your browser and get ready to teach it some new tricks.

In math, two negatives make a positive. In the fledgling world of desktop Linux, unfortunately, this is unlikely to be the case. According to reports from OStatic and others, Xandros is buying Linspire. Who cares, you ask?

One of India's 28 states plans to distribute 100,000 Linux laptops to students there. It sounds like Tamil Nadu's volume purchasing agent decided to use Linux exclusively after being put off by Microsoft's bundling tactics for academic users. The laptops will be purchased in volume by Electronics Corporation of Tamil Nadu (ELCOT), which works as a volume purchaser for students in the state. Tamil Nadu is the Southern-most of India's 28 states, and home to the technology center of Chennai (formerly known as "Madras"). ELCOT says it will purchase more than 100,000 laptops this year, selling them to Indian students for about $800, a considerable mark-down compared to retail value, it says.

Big Buck Bunny is the colorful product of the Peach open movie project: an animated short released online and on DVD. But in addition to the 'toon itself, Peach has produced an altogether different yield: improvements to the Blender 3-D modeling application. Like its predecessor Project Orange, Peach pushed the open source tool forward with the demands of a real-world media production, in a way that hobbyist usage cannot. Could other free software projects use the same model?

NetGear has announced an 802.11g WiFi router and access point made to be hacked. Seemingly created in homage to LinkSys's hacker-friendly "WRT54GL," the WGR614L offers fairly generous complements of CPU power, RAM, and Flash, and supports several commercial and community-supported alternative Linux-based router distributions.

There is no dearth of software that can help you run that indispensable Windows app over Linux. Win4Lin has managed to survive through the years as an inexpensive tool for people who like to pay for support. The recently released Win4Lin 5, available for $30 a pop, has shrugged off the shortcomings of its predecessor and delivers on its "near native-performance" promise. When I reviewed Win4Lin 4 last year, the software wasn't easy to work with, thanks to its half-baked graphical user interface and over-reliance on the command line. It was on the edge of usability, with poor hardware support. Win4Lin 5 promises improvements on all these fronts, along with special pricing for desktop users, especially those running Ubuntu.
