Fedora Core 6 reaches the 1 million mark in just 74 days

Filed under
Linux

A mere 74 days after its release, Fedora Core 6 (Zod) has been downloaded over 1 million times, according to the project's leader. That works out to approximately nine downloads per minute for more than 10 weeks straight.

The Fedora team uses Cacti, an open source data-collection and graphing tool, to track and compute the metrics associated with the release's downloads. Cactus tracks the number of unique IP addresses that check in via yum for updates, rather than simply tracking the number of times FC6 was downloaded. According to comments made on the fedora-announce mailing list by Fedora Project Leader Max Spevack, "This metric is much more useful than tracking downloads, because it demonstrates actual 'installed instances' of FC6 that are making a connection back to our servers in search of updated software."

Currently, Cactus manages data only for the Core package and does not track downloads for Fedora Extras or individual packages. Spevack says discussions will be held prior to the release of Fedora 7 and decisions will be made at that time about what additional data will be tracked in future releases.

Linux-VServer offers a simple way to run several virtual servers on one piece of physical hardware. While it lacks some of the flexibility of more complex virtualization schemes, it is simple to implement and is capable of excellent performance.

Linux-VServer, and similar software like OpenVZ, take a "lightweight" approach to virtualization, essentially segmenting a single Linux kernel environment into virtual machines with separate file systems, process tables, and network addresses.

This is sometimes referred to as a "jail" approach, because it closely resembles a feature called "jails" that is pretty well-known for the FreeBSD operating system. FreeBSD jails are, in turn, an extension of the chroot jail concept, which has long been supported by many UNIX kernels, including the Linux kernel.

NHS open-source Spine 2 platform to go live next week

Last year, the NHS said open source would be a key feature of the new approach to healthcare IT. It hopes embracing open source will both cut the upfront costs of implementing new IT systems and take advantage of using the best brains from different areas of healthcare to develop collaborative solutions. Meyer said the Spine switchover team has “picked up the gauntlet around open-source software”. The HSCIC and BJSS have collaborated to build the core services of Spine 2, such as electronic prescriptions and care records, “in a series of iterative developments”. Read more

What the Linux Foundation Does for Linux

Jim Zemlin, the executive director of the Linux Foundation, talks about Linux a lot. During his keynote at the LinuxCon USA event here, Zemlin noted that it's often difficult for him to come up with new material for talking about the state of Linux at this point. Every year at LinuxCon, Zemlin delivers his State of Linux address, but this time he took a different approach. Zemlin detailed what he actually does and how the Linux Foundation works to advance the state of Linux. Fundamentally it's all about enabling the open source collaboration model for software development. "We are seeing a shift now where the majority of code in any product or service is going to be open source," Zemlin said. Zemlin added that open source is the new Pareto Principle for software development, where 80 percent of software code is open source. The nature of collaborative development itself has changed in recent years. For years the software collaboration was achieved mostly through standards organizations. Read more

Arch-based Linux distro KaOS 2014.08 is here with KDE 4.14.0

The Linux desktop community has reached a sad state. Ubuntu 14.04 was a disappointing release and Fedora is taking way too long between releases. Hell, OpenSUSE is an overall disaster. It is hard to recommend any Linux-based operating system beyond Mint. Even the popular KDE plasma environment and its associated programs are in a transition phase, moving from 4.x to 5.x. As exciting as KDE 5 may be, it is still not ready for prime-time; it is recommended to stay with 4 for now. Read more

diff -u: What's New in Kernel Development

One problem with Linux has been its implementation of system calls. As Andy Lutomirski pointed out recently, it's very messy. Even identifying which system calls were implemented for which architectures, he said, was very difficult, as was identifying the mapping between a call's name and its number, and mapping between call argument registers and system call arguments. Some user programs like strace and glibc needed to know this sort of information, but their way of gathering it together—although well accomplished—was very messy too. Read more
