Earlier this year, we made a decision to run every task on IronWorker inside its own Docker container. Since then, we've run over 300,000,000 programs inside of their own private Docker containers on cloud infrastructure.
Now that we’ve been in production for several months, we wanted to take the opportunity to share with the community some of the challenges we faced in running a Docker-based infrastructure, how we overcame them, and why it was worth it.
It has been a while since I have done a review (almost 3 months, in fact). It has been significantly longer since I have looked at Scientific Linux (over 3 years, in fact). Given that, I figured it might be worthwhile to make this review about Scientific Linux 7.0. I'm just glad that I did it before the time elapsed for something else to come up (around 3 minutes, in fact — OK, I just made that one up to match the other statements).
Julien Danjou is a free software hacker almost all of the time. At his day job, he hacks on OpenStack for eNovance. And, in his free time, he hacks on free software projects like Debian, Hy, and awesome. Julien has also written The Hacker's Guide to Python and given talks on OpenStack and the Ceilometer project, among other things.
Prior to his talk at OpenStack Summit 2014 in Paris this year, we interviewed him about his current work and got some great insight into the work going on for the Ceilometer project, the open source telemetry project for OpenStack.
"Open source hardware is hardware whose design is made publicly available so that anyone can study, modify, distribute, make, and sell the design or hardware based on that design. The hardware's source, the design from which it is made, is available in the preferred format for making modifications to it. Ideally, open source hardware uses readily-available components and materials, standard processes, open infrastructure, unrestricted content, and open-source design tools to maximize the ability of individuals to make and use hardware. Open source hardware gives people the freedom to control their technology while sharing knowledge and encouraging commerce through the open exchange of designs."
The Jacinto 6, which ships with Linux, Android, and QNX SDKs, has been a popular choice among next-generation GENIVI and Automotive Grade Linux (AGL) based designs. It’s running on GlobalLogic’s AGL-based Nautilus in-vehicle infotainment (IVI) and telematics platform, which currently uses Android and will soon offer Tizen Linux, as well.
I am giving a talk on Simplified Remote Management of Linux Servers at the upcoming LISA14 conference in Seattle, which runs from November 9-14. My talk is 9:45-10:30am on Friday, November 14. LISA is Large Installation System Administration SIG of Usenix.
If you are attending LISA I would enjoy meeting you and discussing anything around system administration, security, and open source in general! Drop me a line and let’s see about scheduling some time.
Over the time our website has shown you how to configure various performance tools for Linux and Unix-like operating systems. In this article we have made a list of the most used and most useful tools to monitor the performance for your box. We provided a link for each of them and split them into 2 categories: command lines one and the ones that offer a graphical interface.
Why are Chromebooks growing while, according to NPD and other analysts, Windows PC sales are declining? ABI Research Analyst Stephanie Van Vactor said in a statement that “Consumers are hungry for a product that is cost effective but also provides the versatility and functionality of a laptop. The growth of the Chromebook market demonstrates a niche that is gaining traction among consumers."
With the Btrfs file-system continuing to stabilize while still adding more functionality and is generating continued interest from more Linux distributions and other open-source projects, I've found it time to run some fresh Btrfs RAID benchmarks to see how the next-generation Linux file-system is performing with its built-in RAID handling.
The Btrfs file-system offers built-in support for RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10 (1+0) modes though the support for RAID 5/6 is still considered most experimental. Besides RAID, a single Btrfs file-system can span multiple devices to yield a larger file-system. In this basic Btrfs RAID benchmarking from Ubuntu 14.10, I used two identical hard drives and tested Btrfs without RAID and then in RAID 0 and RAID 1 modes. For a separate article I'm also working on a RAID 0/1/5/6/10 comparison using for solid-state drives, which should be much more interesting, so just take this article as an introduction.
With Ubuntu 14.10 due for release tomorrow and the development branch of Mir at nearly 2,000 revisions, here's some quick Bazaar stats.
As of writing there's been 1994 revisions to the Mir Bazaar development-branch. Curious to see whether there's been any increase in outside contributions to the Mir display stack outside of Canonical, I ran bzr stats to glean some new statistics.
Advertising Age: Where did the name Red Hat come from?
Ms. Yeaney: Red Hat co-founder Marc Ewing, who developed a Linux operating system distribution product that eventually became Red Hat, attended Carnegie Mellon University. When he was on campus, he used to wear a red cap his grandfather gave him. When people had issues with computer software, they'd say, "Go find the guy with the red hat," and the name stuck. Except now it's a fedora.
Makulu Linux Cinnamon Debian Edition. Whew, that's a mouthfull, isn't it? I have said before that Makulu is my favorite distribution for the pure joy of Linux. Full of great graphics, bells and whistles galore, and overflowing with pretty much every package, application or utility you can imagine. The final release of this version is due out next Monday, 27 October, barring unexpected obstacles.
Linux is a great alternative to Windows for those seeking a more secure and liberty-friendly "Operating System." Because it is open-source, there are many different “flavors” (called distributions) available. Two of the most popular distributions are Ubuntu and Fedora. They can be downloaded for free from www.ubuntu.com and www.fedoraproject.org. A fairly complete list of Linux distributions can be found at www.distrowatch.com.
The list of allowed smartphones, which US officials may share confidential information has become a bit longer. The National Information Assurance Partnership (NIAP) - a product tester under the supervision of the NSA - announced Tuesday the green light for the S5 Galaxy, Galaxy Note 4 and the tablet Galaxy Note 10.1 (2014 Edition).
