A pint-sized, multi-functional Linux server small enough to hold in the palm of your hand, was released this week into the North American market by Japan-based Plat'Home.
eComStation: Not for Everyone
In the coming months, Serenity Systems and Mensys will be offering the latest release of eComStation, 2.0. This is the new name and face on the venerable OS/2. It's all too easy to find websites discussing the history of OS/2, articles that walk through the installation process, and lists of drivers, software, and so forth. Despite the ardent love for OS/2 one finds in the user groups, it remains a fairly small niche operating system. This has little to do with the technical merits or demerits of OS/2.
What Edubuntu can teach your kids
Edubuntu is a customized version of Ubuntu aimed at children in educational environments. According to the distributions homepage, Edubuntu is "Linux for Young Human Beings." That works out well for me, since I have three of those in my house. I homeschool my children and use Edubuntu on a couple of our computers. My boys love having an operating system that was designed with them in mind, and I appreciate the way its applications encompass the total learning process.
Hardy Heron? Hardly
If there appears to be more interest in the release of Ubuntu 8.04 (Hardy Heron) than the average distribution, I think I should take some of the blame. Last month, a piece which I authored about what I perceived to be the significance of the release commanded extraordinary interest. And thereafter I noticed a spate of something in the nature of copycat pieces springing up all over the web - with no attribution at all.
Creating charts on Web pages with Java and GChart
The Apache-licensed GChart utility lets you quickly generate nice-looking charts on your Web site. GChart is implemented with the Google Web Toolkit (GWT), which we introduced recently. To install GChart, just extract the distribution zip file. You can work with GChart in your own GWT applications by using it in Eclipse. You first have to tell Eclipse where to find the extracted gchart.jar file and modify your GWT module file to include GChart. These last two setups are described in detail in GChart's installation instructions.
KDE Linux reaches 52 million Brazilian kids
Brazil's Ministry of Education ("MEC") is installing Linux in labs used by 52 million schoolchildren, reports KDE developer Mauricio Piacentini. Piacentini's blog post describes MEC's "Linux Educacional 2.0" as "a very clean Debian-based distribution, with KDE 3.5, KDE-Edu, KDE-Games, and some tools developed by the project."
HAMMER Crash Recovery
"HAMMER is going to be a little unstable as I commit the crash recovery code," began DragonFly BSD creator Matthew Dillon, adding, "I'm about half way through it." He went on to list what's left for crash recovery to work with HAMMER, his new clustering filesystem, "I have to flush the undo buffers out before the meta-data buffers; then I have to flush the volume header so mount can see the updated undo info; then I have to flush out the meta-data buffers that the UNDO info refers to; and, finally, the mount code must scan the UNDO buffers and perform any required UNDOs."
Kuali develops open source financial and ERP applications for universities
Financial and ERP applications are arguably the last bastion of proprietary software giants, but the Kuali Foundation wants to eliminate those remaining barriers to open source enterprise systems, at least in the educational realm. Kuali is a nonprofit collection of colleges, universities, commercial companies, and consultants who hope to "bring the proven functionality of legacy applications to the ease and universality of online services." Kuali's first project, Kuali Financial Systems, is already working on its 3.0 release, scheduled for the end of this year.
From camera to website: Building an open source video streamer
YouTube is a very popular web service that allows people to share video content online. Although YouTube and other streaming video websites satisfy many users, you may have reasons to create your own streaming video website. Perhaps you work for a company that wants a more professional face on their media. Or, you may want more control over exactly how your videos are presented.
Protecting directory trees with gpgdir
gpgdir uses GNU Privacy Guard (GnuPG) to encrypt and decrypt files or a directory tree. You could accomplish the same objective by tarring the filesystem up and then encrypting the tar.gz file with GnuPG, but then you would still have to shred or wipe every file in the original directory tree. With gpgdir the whole tree is encrypted in one command.
Sun chum Oracle pushes database buyers to IBM
A couple of years back, Oracle chief Larry Ellison and then Sun CEO Scott McNealy held an event in Redwood City to renew their vows. Oracle signed on to ship Java for ten more years, and Sun started bundling Oracle's database on its servers at no charge. That last bit was meant to give Sun an edge over hardware rivals, although we can't claim to have heard of it ever making a difference in the market and aren't even sure the deal is still going. What we do know is that Oracle is working over Sun customers who have adopted the multi-core T2 processor and its recent successor the T2+. In fact, Oracle looks set on exacting some measure of punishment on Sun customers who - dare we say it - want to use the T2 boxes for databases.
Report: Benchmarking Linux With the Phoronix Test Suite
The Phoronix Test Suite is for testing hardware performance under Linux. It's still very young and incomplete, but it's worth getting acquainted with--it is based on the the scripts developed by the fine folks at Phoronix for hardware testing.
Rt2x00 project for wireless nearing success
If you use wireless networking in GNU/Linux with native drivers, then chances are that you benefit from work done by the Rt2x00 project. You may use the MadWifi Atheros drivers with OpenHal, or drivers for the Realtek RTL8180 chipset, but most likely you use one of the drivers developed by the Rt2x00 for Ralink chipsets. In the nearly four years since the project began, its work has moved from having a reputation for bugginess to the point where some of its drivers are now part of the latest Linux kernels. Recently, Linux.com talked to three of the lead developers on the project about where Rt2x00 has been and where it is going.
Here comes version 8.0 of AVG Anti-Virus Free!
Arguably the world’s most popular free anti-virus software, Grisoft’s AVG, has just been upgraded, set for free download from Friday, the 25th of April. We’re sure AVG’s servers are about to get hammered even harder as millions of AVG 7.5 users take advantage of the new version!
This week at LWN: Notes from the Collaboration Summit
Your editor has certainly attended no shortage of Linux-related conferences. Many of those are developer conferences, which are invariably interesting events. Others are oriented around marketing or outreach, with rather more variable results. The Linux Foundation's Collaboration Summit, which ran from April 8 to 10, is unique, though, in that it attracts representatives from throughout the Linux ecosystem. Developers are not in short supply (though it seemed like there were fewer than last year), but those developers spend three days talking with corporate executives, industry analysts, and, crucially, a number of high-profile users. This mixture of people creates a very different dynamic which supports a whole range of interesting conversations.
The Usefulness Of Linux-Next
Discussing the latest breakage of the linux-next tree, Stephen Rothwell noted that the problem went unnoticed due to the arm tree not currently being included,"this is why I would have liked you to participate in the linux-next tree ...". Arm maintainer Russell King questioned the usefulness, saying,"linux-next will not give me anything which -mm isn't giving me. As I said in the discussion, linux-next value is _very_ small for me. Sorry but true."
Store amaroK Data in MySQL
By default, amaroK stores information about your [music] collection including listening habits and rankings into a SQLite database file on your filesystem. If you only use amaroK on a single computer, this works fine, but if you run it on multiple computers you might want your information to be persistent across machines. amaroK supports the use of a MySQL database for this type of storage, but it does require a bit of a setup beforehand to use. This hack will describe the steps necessary to migrate to a MySQL collection database.
OpenClinica Community Surpasses 3,500 Members
An increase in the interest and use of open source in clinical research has led to rapid growth of the community surrounding the OpenClinica open source clinical trial software from Akaza Research. In April 2007 this community comprised approximately 1,300 registered members. One year later, this figure has increased by 155 percent to over 3,500.
Browsing the Web the old-fashioned way
Are you in the mood for some '90s-style Web browsing with no graphic elements? Or, more realistically, do you work with a Linux console and often need to check something on the Web? If so, get acquainted with text-based Web browsers such as w3m, Lynx, and the similarly named Links. While browsing the Web without a mouse, graphics, fancy fonts, JavaScript, and Java can be sorely restrictive, it can also be quite speedy. If you're a fan of function keys and special commands, you'll be pleased to learn that these browsers provide plenty of shortcuts for every taste. After you gain experience, you'll be able to navigate around with just a few key taps.
OLPC; one excuse per child
Nicholas Negroponte, the head of the One Laptop per Child project, is in the news again, this time trying to rationalise the appearance of Windows XP on the laptop manufactured by the project.
