Why the Linux mainframe is the cloud datacentre

Filed under
Linux

Linux on the server has been respected and regarded in technology circles for many years now.

One of the main reasons for this is that Linux is argued to be especially competent at handling "many processes at once", something Windows has traditionally not done quite so well.

Linux

The foundation thinks that a natural way of promoting the participation of younger people in the Linux kernel development is to reach out to colleges and universities to host training activities where students and faculty learn the ropes of how to contribute to the kernel.

Best Linux desktop: which is ideal for you

Filed under
Linux

Linux is about choice, or so the popular mantra goes, and nothing represents this more than the plethora of desktop environments on offer. Most distros have at least five graphical environments in their repositories, and some offer double-digit numbers of choice. But why? What's the point of all this? Surely it's not a question of having a lot of desktop environments, but of having a single one that works properly. Well, maybe.

Fedora 19 vs. Fedora 20 Beta Benchmarks

Filed under
Linux

Due to Fedora 20 development releases shipping with debug symbols and other non-release-ready code, the tests today were limited to just giving a quick overview of the performance differences between Fedora 20 Beta and Fedora 19. Fedora 19 was tested in both its stock configuration and then installing all available updates. For ruling out some of the performance issues on Fedora 20 Beta due to the debug state, "slub_debug=-" was set as one of the kernel command-line parameters.

In space, no one can hear you scream at Windows XP (anymore)

Filed under
Linux

I’m a little late in my reporting, but this year, in May, the International Space Station (ISS) dumped the last of its laptop installations of the Windows XP operating system to go all Linux.

Furthermore, it dropped Red Hat Linux in favour of Debian 6, according to the Linux Foundation, which provided two training courses geared specifically for the USA/NASA team’s needs.

HDMI dongle turns TVs into giant Android tablets

Filed under
Linux

A startup called BiggiFi is approaching its Indiegogo funding goal for a $79 HDMI dongle that essentially turns HDTVs into supersized Android tablets. The BiggiFi device is claimed to let users run unmodified Android apps on their TVs using their phone or tablet as the TV’s touchscreen — including motion input for games — without screen-mirroring overhead latency.

Linux backdoor squirts code into SSH to keep its badness buried

Filed under
Linux

Security researchers have discovered a Linux backdoor that uses a covert communication protocol to disguise its presence on compromised systems.

The malware ‪was used in an attack on a large (unnamed) hosting provider ‬back in May. It cleverly attempted to avoid setting off any alarm bells by injecting its own communications into legitimate traffic, specifically SSH chatter. SSH is a protocol commonly used to access shell accounts on Unix-like operating systems, a continuous activity for remote administration of websites.

Leftovers: Ubuntu and Derivatives

  • 'Big Bang Theory's' Stuart wears Ubuntu T-shirt
    Am I the only person to notice that comic book shop-owning Stuart (Kevin Sussman) on the "The Big Bang Theory" is wearing an Ubuntu T-shirt on the episode airing Thursday, Feb. 23, 2017? (It's Season 10, Episode 17, if that information helps you.) The T-shirt appearance isn't as overt as Sheldon's mention of the Ubuntu Linux operating system way back in Season 3 (Episode 22, according to one YouTube video title), but it's an unusual return for Ubuntu to the world of "Big Bang."
  • Unity Explained: A Look at Ubuntu’s Default Desktop Environment
    Ubuntu is the most well-known version of Linux around. It’s how millions of people have discovered Linux for the first time, and continues to draw new users into the world of open source operating systems. So the interface Ubuntu uses is one many people are going to see. In this area, Ubuntu is unique. Even as a new user, rarely will you confuse the default Ubuntu desktop for something else. That’s because Ubuntu has its own interface that you can — but probably won’t — find anywhere else. It’s called Unity.
  • A Look at Ubuntu MATE 16.04.2 LTS for Raspberry Pi
    Installing Ubuntu MATE onto my Raspberry Pi 3 was straight forward. You can easily use Etcher to write the image to a microSD card, the partition is automatically resized to fill your microSD card when the pi is powered up for the first time, and then you are sent through a typical guided installer. Installation takes several minutes and finally the system reboots and you arrive at the desktop. A Welcome app provides some good information on Ubuntu MATE, including a section specific for the Raspberry Pi. The Welcome app explains that the while the system is based on Ubuntu MATE and uses Ubuntu armhf base, it is in fact using the same kernel as Raspian. It also turns out that a whole set of Raspian software has been ported over such as raspi-config, rpi.gpio, sonic-pi, python-sent-hat, omxplayer, etc. I got in a very simple couple of tests that showed that GPIO control worked.

  • Takeaways from the Open Source Leadership Summit: Mainstream Open Source, Security, Policy, and Business Models
    The 2017 Open Source Leadership Summit, put on by the Linux Foundation, brought together leaders from the open source community in Lake Tahoe last week to discuss timely open source topics. The topics that came up most throughout the conference included: open source becoming mainstream, future open source business models, security in a time where everything is connected, and a call to action to be active in technology policy. Open source is becoming a larger focus for major companies, from Toyota to Disney to Walmart. While open source vendors continue to look to the Red Hat model as one of the most successful open source business models to date, entrepreneurs believe there are new models that can surpass this success. As the world becomes ever more connected to the internet, there are general concerns about security, and a call to take action in policymaking. Read on below to learn more about the conversations at the Open Source Leadership Summit.
  • Persistent Memory Usage within Linux Environment by Maciej Maciejewski & Krzysztof Czurylo, Intel
  • Persistent Memory Usage in Linux
    In most cases, when a machine crashes or fails, we lose whatever we had loaded into memory, which for some applications can result in quite a bit of time and effort to recover when the system comes back online. At LinuxCon Europe, Maciej Maciejewski, Senior Software Engineer at Intel, talked about how persistent memory can be used to retain its contents after a power failure.
  • Amidst Bias, Women Work to Find a Place in Open Source Communities
    Despite efforts to enhance diversity, women continue to be under-represented in the science, technology, engineering and math (STEM) fields, and open-source software is no different. A talk at the Linux Foundation’s Open Source Leadership Summit (OSLS), held last week in Lake Tahoe, highlighted some of the issues facing women in the open source community, from low participation to gender bias and unequal pay to overall job satisfaction.
  • Engineer Finds Passion and Community With Kids On Computers
    If you love technology, you can find a space for yourself and connect with others around mutual interests, according to Avni Khatri, president of Kids on Computers (KoC), a nonprofit that sets up computer labs using donated hardware and open source software in areas where kids have no other access to technology. During LinuxCon North America 2016, Khatri organized Kids Day, a day-long workshop that’s aimed at helping school-aged children get interested in computer programming. For Khatri, it’s also a way of furthering her dream of giving children unlimited access to education and helping them succeed in technology.

  • Thanks to Red Hat, India's biggest stock exchange is now the world's fastest
    "Red Hat is now our backbone. Our business cannot run if Red Hat is not there." That is India's biggest stock exchange's CEO talking. Established in 1875, the Bombay Stock Exchange (BSE) is considered to be Asia’s earliest established stock exchange with an overall market capitalization of $1.43 Trillion in 2016 making it the world's 11th largest. Open Source have had many major wins last year, and this has to be one of the biggest.
  • CORD Partners with xRAN to Bring SDN to the RAN
    The Central Office Re-architected as a Data Center (CORD) open source project is partnering with the xRAN Foundation. The two groups plan to work on a software-based, extensible Radio Access Network (xRAN) architecture. Apparently, the xRAN Foundation is a new standards group that was formed in late 2016. Deutsche Telekom, a founding member, is hosting a press event at Mobile World Congress next week to introduce the group and explain its mission. Other initial members of xRAN include AT&T, SK Telecom, and Intel.
  • OpenStack sets its sights on the next generation of private clouds
    Today, the OpenStack Foundation is launching the latest version of its platform that allows enterprises to run an AWS-like cloud computing platform in their data centers. Ocata, as the 15th release of OpenStack is called, arrives after only a four-month release cycle, which is a bit faster than its usual six-month cycle, which will resume after this release. The reason for this is a change in how the Foundation organizes its developer events over the course of a release cycle. Because of the shorter cycle, this new release focused more on stability than new features, but it still manages to squeeze a number of new features in as well.
