This release includes many new features as well as enhanced stability and performance. Some highlights include: - a new easy-to-use CPU scheduler which includes weights, caps, and automatic SMP load-balancing; - support for Xen-oprofile to allow measurement and optimization of code paths; - greatly enhanced support for unmodified ("hvm") guests including Windows and legacy Linux operating systems; - support for dynamic-allocation and copy-on-write disks ("blktap/qcow"); - packet segmentation offload in guests to improve network performance; - enhanced support for IA64 (IPF) systems; and initial support for Power.
FSMLabs's real-time Linux and BSD distributions now support Abatron's popular "BDI" series debuggers. The BDI debuggers exploit the on-chip debugging interfaces found in many modern processors, and can often obviate expensive hardware such as in-circuit emulators, when used with appropriate software packages, according to FSMLabs.
Parallogic will port its StriaEdge multi-core networking stack to ARM's multi-core ARM11 processor architecture, ARM Ltd. reports. The resulting Linux-based hardware/software design will enable home networking equipment capable of 400Mbps throughputs -- enough for triple-play (voice/video/data) services, on-demand video, and multi-channel HDTV service delivery, ARM says.
In this episode: Linux Reality server move; my initial impressions of the Release Candidate of Ubuntu Edgy Eft; a discussion of OpenSSH with an emphasis on ssh, scp, ssh-keygen, public/private key authentication, and dynamic port forwarding (additional link to PuTTY, a Windows SSH client); a Listener Tip on the Flock web browser; listener feedback.
Performance Technologies (PT) says it has successfully registered a forthcoming version of its commercial Linux distribution with version 3.2 of the Carrier Grade Linux (CGL) specification. The company appears to be the first network equipment provider (NEP) to roll its own CGL-compliant Linux implementation.
The release of Firefox 2.0 brings a slew of new features to millions of Internet users. One largely unheralded feature is the inclusion of the StartCom SSL certificate in the list of Certificate Authorities (CAs).
Recently, it was announced that the Mercurial project, a software revision control program used by projects like Xen and ALSA, among others, has become a member of the Software Freedom Conservancy. Some people may be wondering: What is the Software Freedom Conservancy? How do you become a member? Why would you want to? What does the Conservancy do? Who besides Mercurial are members? And what does it mean to be a member?
Red Hat has been toying with Xen in past Fedora versions, but Core 6 brings with it a fancy new management tool. Those who loathe the command line can now fire up a GUI and control their Xen virtual servers from a convenient console. Red Hat hopes that the graphical aid will encourage more people to play around with Xen, which lets users create multiple operating systems on a single physical server.
Microsoft has modified Windows Vista to prevent a high-profile exploit demonstrated at security conferences this summer but the fix creates as many problems as it solves, according to the security researcher who identified the original problem.
The Red Hat-sponsored, community-supported Fedora Project announced on Oct. 24 that Fedora Core 6 is now available. The latest version of this popular Linux distribution boastsimproved desktop performance, new tools for system administrators and developers, and simplified virtualization management, among other enhancements.
The Gaim 2.0 release is nearing its home stretch. The Gaim team released beta4 last week, with a number of new features and UI improvements. Gaim 2.0 is shaping up as a net improvement over Gaim 1.5, though some features have not changed for the better, and voice support for Google Talk is still missing in action.
Creating presentation-quality PDF and Excel Reports with an OSS product. Preparing presentation-quality reports is an everyday occurrence, so any tool that makes the job easier is worth a look. For developers working with Java, one such is JasperSoft's JasperReports, which is capable of producing a range of outputs, including HTML, PDF, Excel XLS, CSV and XML file formats. The tool can build dynamic presentations from either static data or data retrieved form a database table using an SQL query, and is designed to be integrated directly intoJava/J2EE applications.
In this series of articles we'll examine the existing and emerging technologies that enable machines and humans to easily access the wealth of Web-published data. In this first article, you meet the human-computer conflict, learn the criteria used to evaluate different technologies, and find a brief description of the major techniques used today to enable machine-human coexistence on the Web.
This Saturday, 28 October 2006, a bug triage day will be held. This time we are going to clean up the bugs from Bugzilla for the KDE PIM module, after a successful session for Konqueror several weeks ago. We will meet on the IRC channel #kde-bugs on Freenode to coordinate the whole effort.
After being semi-comfortably ensconced in the world of Microsoft products since the days of Windows 3.0, I recently joined the growing ranks of people who realize the value in switching to open source software. What surprised me most about changing operating systems wasn't the myriad of different Linux distributions (how refreshing) nor the vast control they give users over their systems (what liberation). No, what surprised me most was how friendly and welcoming the open source community has been.
SURFnet IDS, a Distributed Intrusion Detection System (D-IDS). The goal is to provide an early warning system which lets system administrators correlate known and unknown exploits to attacks directed towards their networks.
Seasoned system administrators know that routinely reading system logs is an important task, but reading endless lines from logs is both time-consuming and boring, especially if you are responsible for a large number of busy servers. In this article I will show you how to set up a system that gathers and archives system logs from many network hosts and emails only important or irregular system events to administrators.
Today I successfully installed Vista on my ibm X60 after obtaining a copy of RC2. I also installed Office 2007 Beta. Now I’ve got a triple boot IBM x60 that’s almost too cool for me to type on.
A discussion of dynamic parallel execution is presented. The article mentions some possible alternatives to MPI, offers dynamic execution ideas, and develops some solutions.
