Josh Boyer (Fedora Kernel team member & FESCo Nominee) recently announced the new kernel-playground COPR repo. Basically, this is a repo for users that want to try out some new and shiny (yet not ready for primetime) kernel features in Fedora, such as the overlayfs “union” filesystem, and kdbus (the in-kernel d-bus replacement).
It is important to note that this new kernel-playground is an “unsupported” kernel, designed for developers of the new features they include, as well as curious users that want to test out these bleeding edge features, and that.
System administrators keep our lives and work seamlessly humming. They are the super heroes who often go unnoticed and unrecognized only until things go wrong. And so, leading up to SysAdmin Day on July 25, we're honoring the hard work of our Linux Foundation sysadmins with a series of profiles that highlights who they are and what they do.
Ryan Day is one of nine Linux Foundation system administrators, and is part of the global team that supports developers working on collaborative projects. Here he describes a typical work day, talks about his favorite tools, his nightmare scenario, and how he spends his free time, among other things.
Enter Operating System U, OSu. It’s not Ohio State University with a lower-case “u.” The “u” is for you, the one reading this, and the one wishing to control your operating system. The standout thing about OSu is how much customization it gives to the user. That’s our mission and our statement. (It also happens to be our mission statement, but I’m done with little jokes).
OSu is Linux-based. It boasts a Wayland display server, which I love because it squashes clunky xorg extensions and renders directly. We’re also looking at starlight and customization through GUI’s.
Succeeding last month's NVIDIA 340.17 Linux driver beta is now the first official release in the 340.xx driver series for Linux / Solaris / BSD. The NVIDIA 340.24 driver was released this morning with new features but is heavier on the fixing side.
The main feature to the NVIDIA 340.24 driver (and carried over from the 340.17 driver) is initial support on Linux for G-SYNC monitors. The proprietary NVIDIA Linux driver now has support for dealing with G-SYNC (NVIDIA's variable refresh-rate technology similar in nature to AMD FreeSync and VESA Adaptive-Sync -- the support came just months after we reported NVIDIA was working on G-SYNC Linux support.
The Odroid-XU3 runs on a 5V 4A power supply, and once again features four energy monitoring chips for tracking the Big.Little cores. A plastic enclosure and an active cooler are available, along with numerous optional modules. OS support has been boosted to Android 4.4.2 and Ubuntu 14.04, available with full source code.
Schematics will be posted upon shipment, and community support is available via the Odroid project. The quad-core Exynos4412 based Odroid-U3 board came in at third place after the Raspberry Pi and BeagleBone Black in our recent Top 10 Hacker SBC survey.
Historically, Linux and gaming were like oil and water -- it did not mix. For the most part, this was just accepted as a fact of life. Quite frankly, this was OK as users were more interested in maintaining their box and chatting with other Linux users anyway. However, as time went by, jealousy of DOS, and then ultimately Windows, definitely grew as more and more amazing games were released for Microsoft's operating system. Even Linus Torvalds himself dual-booted Linux and DOS to play Prince of Persia.
New disclosures and investigations into the activities of the U.S. National Security Agency (NSA) have revealed fresh insights about the targets of cyber-surveillance activities. Among the new revelations are details about some of the target locations for the NSA XKeyscore system, which monitors and collects Internet data. According to a report first published in German on Tagesschau on July 3 and followed up by an English language report on DasErste, Linux users are an area of specific interest for surveillance. The report details rules in the XKeyscore source code that identify visitors to the Linux Journal Website, the Tor Onion Router site as well as the Tails Linux distribution site. NSA's interest in Tor has been previously documented in an October 2013 report.
The CamJam EduKit was developed in partnership by Cambridge Raspberry Jam and The Pi Hut, and launched at CamJam this month. Designed to get kids interested in the fascinating world of electronics and programming, CamJam EduKit will soon have them building their own electronic circuits, flashing LEDs, reading button presses and making beeping noises by programming their Raspberry Pi with Python.
Today we are pleased to announce the release of Black Lab Linux for Enterprise 5.0.3 and Black Lab Linux for Education 5.0.3.
Black Lab Linux for Enterprise and Black Lab Linux for Education are commercially supported Linux distributions targeted towards desktop computing. While other Linux distributions focus on the server our sole focus is on the desktop. We have many customers who use Black Lab Linux in different industries. Science, education, law enforcement, music, film and warehouse.
Cisco earlier this year unveiled its plans to build smarter routers and switches to help manage the massive flows of data expected between Internet-connected devices and the data center. This re-architecting of the Internet to bring computing capabilities to the edge of the network is what the company calls “fog computing” and it could help alleviate the data center strain that Gartner analysts predict will come from 26 billion installed units in the Internet of Things by 2020.
Moonlight v0.5 Alpha is the first release and its aimed at hackers and developers wishing to forward their dream of "a simple, lightweight, functional and beautiful desktop environment." Moonlight is written against the Qt5 tool-kit and the desktop environment is designed to be very modular. Moonlight shares some goals and code with the LXQt lightweight desktop project.
The Deepin Desktop Environment is written using Google's Go language and makes use of heavy HTML5. DDE also uses Compiz as its compositing window manager. As in the past some desktop environments / window managers have impaired the full-screen Linux gaming performance, I ran some simple Linux gaming benchmarks on Sunday to see if the Deepin 2014 performance differed at all from upstream Ubuntu 14.04 LTS. Ubuntu 14.04 was tested with the stock Unity 7.2 desktop using Compiz, GNOME Shell 3.10.4, and Xfce 4.10 all from the stock Trusty Tahr archive.
Samuli Suominen of Gentoo expressed some hesitation about this change, "I'd really hate to be forced to fork (or carry huge patchset) unnecessarily (I'm not a systemd hater, I'm not a eudev lover, I'm simply working on what is provided to me by *you*, udev upstream)." Lennart countered, "Oh god. You know, if you come me like this as blame me that I would 'force' you to do something, then you just piss me off and make me ignore you. Anyway, as soon as kdbus is merged this i how we will maintain udev, you have ample time to figure out some solution that works for you, but we will not support the udev-on-netlink case anymore. I see three options: a) fork things, live with systemd, c) if hate systemd that much, but love udev so much, then implement an alternative userspace for kdbus to do initialiuzation/policy/activation. Also note that this will not be a change that is just internal between udev and libudev. We expect that clients will soonishly just start doing normal bus calls to the new udev, like they'd do them to any other system service instead of using libudev. Good luck."
Trust in government is not exactly at an all-time high. Sure, there are oppressive governments such as Iran and China that filter and block web content, but even the USA has a spotty record. With all the news of PRISM and other spying programs, it is hard to tell which way is up anymore.
One way to solve this dilemma is through transparency and honesty. Unfortunately, as long as governments use closed-source software, it is hard to audit and trust the actions. Today, Canonical announces that not only has Munich taken an open approach to computing with Ubuntu, but the city is saving millions of euros too. Using open-source software and saving money? Hell, maybe all governments should make the switch to Linux.
