"ZDNet is reporting that Oracle has added code to the Linux kernel for ensuring data integrity. The code has been developed in partnership with Emulex and was recently accepted into the 2.6.27 kernel release." According to the article, "The code adds metadata to data at rest or in transit, to monitor whether that data has been corrupted. It helps make sure that I/O operations are valid by looking at that metadata — which acts as verification information — exchanged during data transmissions."
The latest version of Fedora, the Linux-based operating system, gives users a peek at what they can expect to see in future Linux distributions from Red Hat and other vendors. Fedora 10 offers a broad security framework and new audit capabilities, and gives Linux enthusiasts a good way to upgrade from Fedora 9. However, those who use the Linux-based OS shouldn't expect any support from Red Hat. - Fedora 10 is the latest version of the community-supported, Linux-based operating system that serves as the proving ground for future Red Hat software products. As a result, Fedora offers organizations and individuals early access to the state of the art in the Linux and open-source world.
You probably know that reading from RAM is a lot of faster than reading files from the hard drive, and reduces your disk I/O. This article shows how you can store files and directories in memory instead of on the hard drive with the help of tmpfs (a file system for creating memory devices). This is ideal for file caches and other temporary data (such as PHP's session files if you are using session.save_handler = files) because the data is lost when you power down or reboot the system.
Virtualized computing environments can take advantage of built-in virtualization support in modern dual-core processors, but when it comes to 3-D acceleration in virtual machines, almost all fall flat on their faces. VMGL is a little-known application written as part of Google's Summer of Code 2006 program that lets OpenGL apps running inside a virtual machine take advantage of the graphics hardware acceleration on the host. It has limitations, but if you want 3-D in VMs, VMGL is your best bet.
MNonitor your network with PasTmon passive traffic monitor. The PasTmon passive traffic monitor enable you to recording which clients are interacting with which services, when and how long things took. You can then use the application's PHP Web interface to investigate these figures to see if any host is connecting to Web services that it shouldn't, or is contacting services suspiciously more frequently than you would expect for normal operation, or when response times become excessively long.
Several readers pointed out a ComputerWorld UK blog piece on the expanding ripples of the Vista fiasco. Glyn Moody quotes an earlier Inquirer piece about Vista, which he notes "has been memorably described as DRM masquerading as an operating system": "Studies carried out by both Gartner and IDC have found that because older software is often incompatible with Vista, many consumers are opting for used computers with XP installed as a default, rather than buying an expensive new PC with Vista and downgrading. Big business, which typically thinks nothing about splashing out for newer, more up-to-date PCs, is also having trouble with Vista, with even firms like Intel noting XP would remain the dominant OS within the company for the foreseeable future." Moody continues: "What's really important about this is not so much that Vista is manifestly such a dog, but that the myth of upgrade inevitability has been destroyed. Companies have realized that they do have a choice — that they can simply say 'no.' From there, it's but a small step to realizing that they can also walk away from Windows completely, provided the alternatives offer sufficient data compatibility to make that move realistic."
ruphus13 points out news from the Linux Foundation, which announced that all major Linux distributions meet certification requirements for the US Department of Defense's IPv6 mandates. The announcement credits work done by the IPv6 Workgroup, whose members include IBM, HP, Nokia-Siemens, Novell and Red Hat. Quoting: "Linux has had relatively robust IPv6 support since 2005, but further work was needed for the open source platform to achieve full compliance with DoD standards. The Linux Foundation's IPv6 workgroup analyzed the DoD certification requirements and identified key areas where Linux's IPv6 stack needed adjustments in order to guarantee compliance. They collaboratively filled in the gaps and have succeeded in bringing the shared technology into alignment with the DoD's standards."
kev009 writes to recommend his editorial overview of the past, present and future of Linux file systems: ext2, ext3, ReiserFS, XFS, JFS, Reiser4, ext4, Btrfs, and Tux3. "In hindsight it seems somewhat tragic that JFS or even XFS didn't gain the traction that ext3 did to pull us through the 'classic' era, but ext3 has proven very reliable and has received consistent care and feeding to keep it performing decently. ... With ext4 coming out in kernel 2.6.28, we should have a nice holdover until Btrfs or Tux3 begin to stabilize. The Btrfs developers have been working on a development sprint and it is likely that the code will be merged into Linus's kernel within the next cycle or two."
ekimd writes "Fedora 10, aka 'Cambridge,' was released today. Some of the major features include: 'wireless connection sharing enables ad hoc network sharing, better setup and use of printers through improved management tools, virtualization storage provisioning for local and remote connections now simplified, SecTool is a new security audit and intrusion detection system.' Versions of major software include: Gnome 2.24, Eclipse 3.4 and RPM 4.6. A features list can be found here." Reader Nate2 suggests LinuxFormat's detailed look at the new release, and adds a few more details about the software it contains: the release includes "a new graphical boot-up sequence, OpenOffice.org 3, many improvements to sound support via PulseAudio and other updates."
When Maine State Employees Association SEIU Local 1989 needed software to safeguard confidential information and ward off online threats, it found an open source solution. The labor union, which represents more than 15,000 public and private sector workers throughout the State of Maine, chose Untangle's open source Gateway platform, a solution that not only helps keep confidential data away from prying eyes, but also protects against spam, spyware, phishing, and viruses.
TRNick writes "How can developers who are working for free protect themselves and avoid getting exploited by business users of Linux? TechRadar has an interview with former Fedora project leader Max Spevack to find out how his new role as manager of the community architecture team is designed to help. Quoting: 'About two-thirds of the Fedora packages are maintained by community people, and if we didn't have that community, that chunk of work would either not get done, which would significantly harm Red Hat's entire value, or would have to made up by more [paid] engineers. The challenge on the flip side of that is to make sure that everyone in the Fedora community feels valued, that everyone who contributes can be proud of the way that Red Hat uses their code.'"
Christoph Haas writes "A picture is worth a thousand words. And thanks to screenshots.debian.net this finally comes true for Debian packages. The new website was launched just a week ago and has already collected screenshots for 740 packages shipping with the Linux distribution — with new uploads pouring in every hour. Debian users can finally get an impression of how an application would look before installing it."
Ashmash writes "Phoronix is reporting on a new Linux driver nVidia is about to release that brings PureVideo features to Linux. This video API will reportedly be in nVidia's 180 series driver for Linux, Solaris, and *BSD. PureVideo has been around for several nVidia product generations, but it's the first time they're bringing this feature to these non-Windows operating systems to provide an improved multimedia experience. This new API is named VDPAU, and is described as: 'The Video Decode and Presentation API for Unix (VDPAU) provides a complete solution for decoding, post-processing, compositing, and displaying compressed or uncompressed video streams. These video streams may be combined (composited) with bitmap content, to implement OSDs and other application user interfaces.'"
Currently in late beta, the Sun Presenter Console (SPC) is Sun Microsystems' latest extension for OpenOffice.org and StarOffice. Other extensions from Sun in the last year, such as the Sun PDF Import Extension, Sun Presentation Minimizer, and Sun Weblog Publisher, have sometimes been lacking in design and sometimes buggy, but all of them are so invaluable that you might wonder why they are extensions instead of new features. SPC is no exception. It gives slide show presenters a separate view of their presentation and some tools to help them organize and deliver their talks, but includes no indication of how to set it up or use it.
My employer, Warnbro Community Library in Western Australia, had a problem with wasted paper from printing. Library patrons often sent unnecessary print jobs to the printers, then refused to pay for them, leaving reams of unclaimed paper. The library needed a print queue to enable library staff to control patrons' print jobs. It needed to be easy to set up and maintain and cost nothing. We found the answer in using Linux as a print server.
There are many ways to share files with teams of people, but few require only a Web browser for access and let you choose from tens of different ways of authenticating user access to the files. Such lightweight and universal access is the promise of Gollem, a file manager that runs in your Web browser. With it you can connect to and manage your files on a WebDAV, FTP, or traditional filesystem or SQL database.
An anonymous reader notes an Inquirer story reporting on something of a breakthrough in virtual machine management — a demonstration (not yet a product) of migrating a running virtual machine across CPUs from different vendors (video here). "RedHat and AMD have just done the so called impossible, and demonstrated VM live migration across CPU architectures. Not only that, they have demonstrated it across CPU vendors, potentially commoditizing server processors. This is quite a feat. Only a few months ago during VMworld, Intel and VMware claimed that this was impossible. Judging by an initial response, VMware is quite irked by this KVM accomplishment and they are pointing to stability concerns. This sound like scaremongering to me... All the interesting controversy aside, cross vendor migration is [obviously] a good thing for customers because it avoids platform lock-in."
Many network-attached storage (NAS) devices, in addition to offering network storage, offer features such as VPN access, calendaring, wikis, and even an iTunes server. The open source Amahi Linux Home Server provides all of that and more in a complete NAS box integrated with a Fedora 9 base.
Open source multimedia specialist Collabora is hiring developers to work on the nonlinear video editor PiTiVi. The Cambridge, UK-based company contributes heavily to the GStreamer media framework and other GStreamer-dependent projects, so PiTiVi is a natural fit -- and it fills a sorely needed niche on the Linux desktop.
The pam_mount project lets you unlock an encrypted filesystem automatically when you log in. The same password used to log in is used as the key to unlock the encrypted filesystem, so you only need to type it once. Using this method, you can easily share a laptop and have only a single user's home directory unlocked and mounted when he logs in. And pam_mount can mount any filesystem, not just encrypted filesystems, so you can use it, for example, with an NFS share that you are interested in but which you might not like to leave mounted when you are not logged in.
