The Companies That Support Linux: Rackspace

Filed under
GNU
Linux
Server
Interviews

Rackspace has lately been in the news for its stock market gains and a potential acquisition. But over the past 16 years the company has become well known, first as a web hosting provider built on Linux and open source, and later as a pioneer of the open source cloud and founder of the OpenStack cloud platform.

In May, Rackspace became a Xen Project member and was one of three companies to join the Linux Foundation as a corporate member, along with CoreOS and Cumulus Networks.

“Many of the applications and infrastructure that we need to run for internal use or for customers run best on Linux,” said Paul Voccio, Senior Director of Software Development at Rackspace, via email. “This includes all the popular language frameworks and open virtualization platforms such as Xen, LXC, KVM, Docker, etc.”

In this Q&A, Voccio discusses the role of Rackspace in the cloud, how the company uses Linux, why they joined the Linux Foundation, as well as current trends and future technologies in the data center.

What makes this important, even vital, news to the larger world of system administrators, datacenter managers, and cloud architects, is that Google, Red Hat, and Parallels are now helping build the program. Indeed, they will work with Docker as core maintainers of the code. Canonical's Ubuntu container engineers will also be working on it.

The Core i7 4790K has an 88 Watt TDP over 84 Watts on the Core i7 4770K but aside from the higher clock frequencies and thermal/power improvements, the i7-4790K shares much in common with the i7-4770K when it comes to being a quad-core CPU with Hyper Threading, 22nm manufacturing, DDR3-1600MHz memory support, and sports HD Graphics 4600. Like the i7-4770K, the HD Graphics 4600 top out at 1.25GHz. Pricing on the Intel Core i7 4790K is currently about $340 USD from major Internet retailers.

Linux 3.15 Speeds Up Suspend/Resume Performance

Filed under
Linux

The suspend and resume code impacts users who run Linux on laptop computers where there is a need to suspend disk and operating system operations when a device is closed and then start up again when the device is opened. Williams noted that his code contribution was inspired by an analysis and proposal from Intel developer Todd Brandt. Brandt's proposal specifically dealt with a suspend/resume speed improvement, enabling a rapid wakeup from a device's suspend state

How does the cloud affect the everyday linux user?

Filed under
Linux

Cloud computing has really become the buzz term for any online service. Your web browser is a client connecting to a server or clusters of servers hosted anywhere in the world. The point is that you don't care. You don't need to know.

Generally speaking I have barely touched the surface. We all use the cloud everyday and most of us don't even think about it.

How does the cloud affect the everyday linux user? It turns out quite a bit.

Is the cloud a good or bad thing? Neither. Each service has to be judged on it's own merits.

The term "The Cloud" is just something marketing people and the technical press get excited about. Anyone remember when they kept using the term "Web 2.0"?

  • Blockchain Moves Beyond its 'Moonshot' Phase
  • Some reading
    I've complained previously about disliking benchmarking. More generally, I'm not really a fan of performance analysis. I always feel like I get stuck at coming up with an approach to "it's going slower, why" beyond the basics. I watched a video of Brendan Gregg's talk from kernel recipes, and ended up going down the black hole1 of reading his well written blog. He does a fantastic job of explaining performance analysis concepts as well as the practical tools to do the analysis. He wrote a book several years ago and I happily ordered it. The book explains how to apply the USE method to performance problems across the system. This was helpful to me because it provides a way to generate a list of things to check and how to check them. It addresses the "stuck" feeling I get when dealing with performance problems. The book also provides a good high level overview of operating systems concepts. I'm always looking for references for people who are interested in kernels but don't know where to start and I think this book could fill a certain niche. Even if this book has been out for several years now, I was very excited to discover it.
  • Introducing container-diff, a tool for quickly comparing container images
    The Google Container Tools team originally built container-diff, a new project to help uncover differences between container images, to aid our own development with containers. We think it can be useful for anyone building containerized software, so we’re excited to release it as open source to the development community.

So grab your cup of whatever you’re probably drinking as we delve into this app a little. NATTT is an acronym for “Not Another Time Tracking Tool”; a free and multi-platform app with which you can keep track of your work and how much you have spent at it.

  • Compact DAQ systems offer a choice of 12- or 16-bit I/Os
    Advantech’s Linux-ready “MIC-1810” and “MIC-1816” DAQ computers offer 12- and 16-bit analog I/O, respectively, plus 24x DIOs, Intel CPUs, and 4x USB ports. Advantech’s MIC-1810 and MIC-1816 are digital acquisition computers that run Linux or Windows 7/8/10 on Intel 3rd Gen “Ivy Bridge” processors. If the aging CPU is a turn-off, keep in mind that many DAQ applications don’t require that much processing power, and perhaps Advantech’s “entry-level” label for the systems extends to the price, as well. The 165 x 130 x 59mm, DIN-rail mountable systems should also prove useful for environments with limited space.

  • Kaspersky blames NSA hack on infected Microsoft software
    Embattled computer security firm Kaspersky Lab said Thursday that malware-infected Microsoft Office software and not its own was to blame for the hacking theft of top-secret US intelligence materials. Adding tantalizing new details to the cyber-espionage mystery that has rocked the US intelligence community, Kaspersky also said there was a China link to the hack.
  • Investigation Report for the September 2014 Equation malware detection incident in the US
    In early October, a story was published by the Wall Street Journal alleging Kaspersky Lab software was used to siphon classified data from an NSA employee’s home computer system. Given that Kaspersky Lab has been at the forefront of fighting cyberespionage and cybercriminal activities on the Internet for over 20 years now, these allegations were treated very seriously. To assist any independent investigators and all the people who have been asking us questions whether those allegations were true, we decided to conduct an internal investigation to attempt to answer a few questions we had related to the article and some others that followed it:
  • Kaspersky: Clumsy NSA leak snoop's PC was packed with malware
    Kaspersky Lab, the US government's least favorite computer security outfit, has published its full technical report into claims Russian intelligence used its antivirus tools to steal NSA secrets. Last month, anonymous sources alleged that in 2015, an NSA engineer took home a big bunch of the agency's cyber-weapons to work on them on his home Windows PC, which was running the Russian biz's antimalware software – kind of a compliment when you think about it. The classified exploit code and associated documents on the personal system were then slurped by Kremlin spies via his copy of Kaspersky antivirus, it was claimed.

  • Open Source Networking Days: Think Globally, Collaborate Locally
    Something that we’ve learned at The Linux Foundation over the years is that there is just no substitute for periodic, in-person, face-to-face collaboration around the open source technologies that are rapidly changing our world. It’s no different for the open networking projects I work with as end users and their ecosystem partners grapple with the challenges and opportunities of unifying various open source components and finding solutions to accelerate network transformation. This fall, we decided to take The Linux Foundation networking projects (OpenDaylight, ONAP, OPNFV, and others) on the road to Europe and Japan by working with local site hosts and network operators to host Open Source Networking Days in Paris, Milan, Stockholm, London, Tel Aviv, and Yokohama.
  • The Open-Source Driving Simulator That Trains Autonomous Vehicles
    Self-driving cars are set to revolutionize transport systems the world over. If the hype is to be believed, entirely autonomous vehicles are about to hit the open road. The truth is more complex. The most advanced self-driving technologies work only in an extremely limited set of environments and weather conditions. And while most new cars will have some form of driver assistance in the coming years, autonomous cars that drive in all conditions without human oversight are still many years away. One of the main problems is that it is hard to train vehicles to cope in all situations. And the most challenging situations are often the rarest. There is a huge variety of tricky circumstances that drivers rarely come across: a child running into the road, a vehicle driving on the wrong side of the street, an accident immediately ahead, and so on.
  • Fun with Le Potato
    At Linux Plumbers, I ended up with a Le Potato SBC. I hadn't really had time to actually boot it up until now. They support a couple of distributions which seem to work fine if you flash them on. I mostly like SBCs for having actual hardware to test on so my interest tends to be how easily can I get my own kernel running. Most of the support is not upstream right now but it's headed there. The good folks at BayLibre have been working on getting the kernel support upstream and have a tree available for use until then.

Some of the changes are arguably overdue: syntax highlighting and error checking for CSS editing and cutting custom HTML are neither scarce nor innovative. They'll be welcomed arrival will likely be welcomed anyway, as will newly-granular roles and permissions for developers. The new release has also added version 4.2.6 of MediaElement.js, an upgrade that WordPress.org's release notes stated has removed dependency on jQuery, improves accessibility, modernizes the UI, and fixes many bugs.”

Ubuntu: New Users, Unity Remix, 18.04 LTS News

  • How to Get Started With the Ubuntu Linux Distro
    The Linux operating system has evolved from a niche audience to widespread popularity since its creation in the mid 1990s, and with good reason. Once upon a time, that installation process was a challenge, even for those who had plenty of experience with such tasks. The modern day Linux, however, has come a very long way. To that end, the installation of most Linux distributions is about as easy as installing an application. If you can install Microsoft Office or Adobe Photoshop, you can install Linux. Here, we’ll walk you through the process of installing Ubuntu Linux 17.04, which is widely considered one of the most user-friendly distributions. (A distribution is a variation of Linux, and there are hundreds and hundreds to choose from.)
