You might know how to write code or build applications, but do you know what is required of a good Linux sysadmin?
The coming of Fusion, both as products and architecture, is inevitably set to change the ground on which applications development has stood for many years, as is its part in the move towards delivery Service Oriented Architectures (SOA). But the company is aware it is now stepping out into uncharted ground, where some of its claims are inevitably based on assumption.
In a move to make the freely distributed Linux operating system a stronger alternative to Microsoft Corp.'s Windows, a group of major Linux distributors announced Friday they have united on a standard set of components for desktop versions of Linux.
This week, Debian, Fedora, FreeBSD, Gentoo, Red Hat, and Ubuntu released updates to address security problems with Firefox, Cacti, the Mozilla Suite, the GNOME Display Manager (GDM) and several others.
On the machine's front is a computer screen running on a Linux operating system. It displays menus of possible flavors and allows the user to create any combination, such as low-fat coffee ice cream with Oreo cookies. If the machine runs out of a flavor, it stops putting it on the menu and sends a message to MooBella asking for a refill.

Scheduling Backup Jobs using at and crontab
Xandros, provider of easy-to-use Linux alternatives to Windows, and TOLIS Group, developer of the ultra-reliable BRU announced an agreement to integrate a complete BRU backup and recovery system into the forthcoming Xandros Server – the first truly viable alternative to the dominance of Microsoft Windows servers in the SMB (small-to-medium business) and departmental markets.
While explaining the new splice() and tee() buffer management system calls [story], Linus Torvalds made reference to some possible future extensions. This included vmsplice(), a system call "to basically do a 'write to the buffer', but using the reference counting and VM traversal to actually fill the buffer." Reviewing the implications of using such a system call lead to a comparison with FreeBSD's ZERO_COPY_SOCKET which uses COW (copy on write).
Linus explained that while this may look good on specific benchmarks, it actually introduces extra overhead, "the thing is, the cost of marking things COW is not just the cost of the initial page table invalidate: it's also the cost of the fault eventually when you _do_ write to the page, even if at that point you decide that the page is no longer shared, and the fault can just mark the page writable again." He went on to explain, "The COW approach does generate some really nice benchmark numbers, because the way you benchmark this thing is that you never actually write to the user page in the first place, so you end up having a nice benchmark loop that has to do the TLB invalidate just the _first_ time, and never has to do any work ever again later on." Linus didn't pull any punches when he summarized:
"I claim that Mach people (and apparently FreeBSD) are incompetent idiots. Playing games with VM is bad. memory copies are _also_ bad, but quite frankly, memory copies often have _less_ downside than VM games, and bigger caches will only continue to drive that point home."
Another Interesting article about Linux on desktop ability. Can linux really cut it as a valid end user desktop platform? Well... Judge for yourself I guess. As for me and mine... We use linux. :-)
I'm a young Linux developer from Serbia and Montenegro and a big fan of networking under Linux. Most of my favorite tools help with Linux networking and data security.
vector The third release candidate of VectorLinux 5.1 "Standard" Live CD has been released: "The VectorLinux team is proud to announce the release of the VL-5.1 standard RC3 Live CD. This version fixes bugs from RC2. We have added GParted for all of your GUI partitioning needs, and an icon for the Live CD installer.
After chatting with X Window System founder Jim Gettys yesterday about One Laptop Per Child, I happened to pass today, on the highway to the conference, the first favela I've ever seen.
- Texstar has announced the first release of the "MiniME" edition of PCLinuxOS 0.93, a minimal and customisable desktop system with KDE: "PCLinuxOS 0.93 MiniME is available for download and testing. This release is for those who have been asking for a minimum live CD / hard disk install allowing for full personalization. This release includes 2.6.15-oci3 kernel, basic KDE 3.5.2 desktop (kdebase and kdelibs only), PCLOS Control Center, the Synaptic software installer and a customized X.Org server from Thac to provide additional 3D support for many graphic cards.
OSDir has some cool screenshots of this MiniME edition in the PCLinuxOS 0.93 MiniME Screenshot Tour.
Libraries have been around for a lot longer than software, and librarians long ago learned many of the data management lessons that have only now begun to surface in the world of software and databases. By contrast, software is a young, rapidly changing field, and this has affected its outlook. Five years may seem like an eternity in software development, but in the archival business, it’s just the blink of an eye.
In this extensive review, Cluster Monkey Jeff Layton, provides an overview of the available Linux cluster interconnect technologies. This article is the first ever attempt to provide a comprehensive look at cluster interconnects. It concludes with two tables summarizing key features and pricing for various size clusters.
Yesterday I arrived in Porto Alegre, in the South of Brazil, and introduced my readers to the Fórum Internacional Software Livre. At that time I had met some of the animals but had not yet attended the circus. Today I experienced the full excitement of being with thousands of people with many different interests: free software developers, students, government leaders, and more. I estimated a full two thousand people in today’s keynote presentation, which featured a range of government leaders and a little video in which the Brazilian national anthem was played by a variety of musicians from different regions and ethnic backgrounds.
- Jani Monoses has announced the first public beta release of Xubuntu, the latest addition of the growing tree of Ubuntu derivatives: "We are pleased to announce that the first public beta release of Xubuntu, the latest official addition to the Ubuntu family of derivative distributions has arrived. Xubuntu is built around the solid Ubuntu core and the friendly and relatively light-weight XFce desktop environment, with the specific goal of providing a nice user experience even on older hardware. This release includes a recent code snapshot of the upcoming XFce 4.4 desktop environment.
OSDir has some great shots of the latest Xubuntu in the Xubuntu 6.06 Beta Screenshot Tour.
he slowly gathering backlash against Larry's comments are almost as predictable as Ellison's words themselves. Larry's outburst blends some good-old-fashioned ERP/CRM vendor politics calculated to freeze the competition with the passions of the jilted lover who knows he's lost something of great value.
Microsoft makes it sound like the big daddy of server migrations, but GoDaddy.com's move from Linux to Windows isn't exactly the glowing endorsement Microsoft makes it out to be.
