Instant backups with smbmount and grsync

Need a simple yet effective way to back up your laptop or desktop machine to a network-attached storage device or a network hard disk running Samba? Using Samba's smbmount utility and the grsync backup tool, you can set up a backup system that is both reliable and straightforward in use. And since both programs are available as packages for most Linux distributions, you don't have to get your hands dirty compiling from source code and fiddling with settings.

Windows vs. Linux vs. OS X: CIO John Halamka Tests Ubuntu

Last summer, CareGroup CIO John Halamka began looking for a viable alternative to the Microsoft Windows desktop operating system. After 16 years using Windows, he had enough of its instability and the countless updates that automatically installed themselves on his computer—often at inopportune times, like when he was in the middle of a presentation. As CIO of a health-care organization and affiliated medical school with 40,000 employees and 9 million patient records, Halamka has to be sure that the computers in the hospital, its administrative offices and medical school are secure, stable and easy to use.

64 Studio 2.0 'Electric' released

Five days ago, the guys at 64 Studio released their official 2.0 'Electric' version. With a realtime 2.6.21 kernel and lots of preconfigured audio/video productivity applications, it's well worth a look.

Laying to Rest the Mandriva/PCLinuxOS Debate

The one thing about FOSS that I love is that you can take whatever you need from various sources and build what you opine is a better wheel. Take Ubuntu for instance...they took Debian and made it into something that many users are happy with.

Is this wrong? Not at all. Each day, many non-commercial distro makes wake up and check various distributions for updated security fixes. They pull source rpms, updated tar.gz's, and debs into their distro, make minor adjustments, and drop it into their repository. Distros share with one another...they take and hopefully give back. If not monetarily, at least by the number of users that they have that may report bugs or provide fixes.

So what's the beef that some Distrowatch Weekly commenter's seem to have with PCLinuxOS? During the past 3 weeks of comments on the DW, some have been hounding PCLinuxOS with accusations saying that the developers hide things from their community and that PCLinuxOS eradicates changelogs and/or lights small dogs on fire while chopping kittens to bits in blenders, etc. Let's take a look at these "myths" shall we?

Software Freedom Law Center clears OpenHAL for further development

An investigation by the Software Freedom Law Center (SFLC) has determined that OpenHAL -- which facilitates Linux wireless connections for LAN cards using Atheros Communications technology -- does not incorporate any elements that might infringe on copyrights held by Atheros.

Troubleshooting Linux Audio, Part 2

In my last installment of this series I introduced a variety of GUI-based tools that can help you discover more about your system to help identify potentially troublesome components. This week we'll look at some of the command-line utilities that do similar work. In fact, some of these utilities are the engines underneath the more attractive GUI tools, and there may be good reasons to employ the engines directly instead of relying upon their graphic incarnations.

Desktop Backgrounds For Minimalist Window Managers Revisited

Back in February I wrote about using xli to add a desktop background of your choice to a minimalist window manager. I chose to write about xli for two reasons. First, several window manager developers choose to use xli by default. For example, if you look at a .jwmrc file, the configuration file used by JWM, a lightweight window manager I am rather fond of, you will see that xli is used in the section. The second and perhaps more important reason I chose to write about xli is because it’s what I knew and used for years. One thing about Linux and UNIX: there are always different ways to do things. It turns out that many distros include something a bit newer and perhaps better than xli.

Turn your computer into a media center PC with GeeXBoX 1.1

GeeXBoX, a small media center Linux live CD distribution, can run from any small device, such as a USB disk or a wallet CD-R, and can play both disk-based media like DVDs and online media like Icecast streams. The project has been in development for several years and has just released version 1.1. I fed it every kind of media file I could lay my hands on -- Ogg, MP3, MP4, AVI, DVDs, VCDs, and their ripped versions -- and it played them all without a hiccup. But what makes GeeXBoX a fantastic distribution is its ease of use and malleability.

OpenOffice.org Calc: Pivot tables by another name

DataPilots are OpenOffice.org Calc's equivalent of what MS Excel and other spreadsheets call pivot tables. Under any name, they are a tool for extracting and summarizing the information contained in spreadsheet cells in a more convenient form. Using a DataPilot, you can immediately see relationships between different pieces of data that would be difficult -- if not impossible -- to find using formulas, and tedious to extract manually. In effect, a DataPilot gives you something of the power of using a database without actually switching out of a spreadsheet. Small wonder, then, that over half of spreadsheet users are said to use datapilots or pivot tables.

Linux: CFS and 3D Gaming

Some of the concerns expressed about the Completely Fair Scheduler were reports that it might not handle 3D games as well as the SD scheduler. In a recent thread, Ingo Molnar noted, "people are regularly testing 3D smoothness, and they find CFS good enough and that matches my experience as well (as limited as it may be). In general my impression is that CFS and SD are roughly on par when it comes to 3D smoothness."

Torvalds rebukes desktop critics

Linus Torvalds, creator and maintainer of the Linux operating system kernel, has reacted angrily to suggestions that the kernel's development process is skewed in a way that prevents improvements on the desktop. Torvalds was responding to criticism by programmer Con Kolivas, who had developed a patch designed to improve the performance of specific Linux desktop features.

Do we need an open hardware license?

Nokia researcher Jamey Hicks recently proposed a Open Source Hardware License (OSHL) for approval by the Open Source Initiative (OSI). Is there a need for a hardware-specific license? If so, what makes hardware different from software?
