  • Linux Kernel 3.18 Reaches End of Life, Users Urged to Move to Linux 4.9 or 4.4

    Today, February 8, 2017, renowned Linux kernel maintainer Greg Kroah-Hartman put an end to the release cycle of the long-term supported (LTS) Linux 3.18 kernel series by releasing what appears to be the last hotfix.

    Linux kernel 3.18.48 LTS is here and is the last in the series, which was marked for a January 2017 extinction since mid-April last year. According to the appended shortlog, the new patch changes a total of 50 files, with 159 insertions and 351 deletions.

  • Inside Real-Time Linux

    Real-time Linux (RTL), a form of mainline Linux enabled with PREEMPT_RT, has come a long way in the past decade. Some 80 percent of the deterministic PREEMPT_RT patch is now available in the mainline kernel itself. Yet, backers of the strongest alternative to the single-kernel RTL on Linux -- the dual-kernel Xenomai -- continue to claim a vast superiority in reduced latency. In an Embedded Linux Conference Europe presentation in October, Jan Altenberg rebutted these claims while offering an overview of the real-time topic.

  • Atom 1.14

    A fundamental component of the text editor called the display layer has been redesigned to rely on a new data structure that is implemented in C++. These changes enable Atom to open larger files more quickly while using much less memory. Improvements in this area are ongoing, so expect more in upcoming releases.

  • Atom 1.14 Hackable Text Editor Launches with Improved Large File Performance

    GitHub's Ian Olsen is announcing today, February 8, 2017, the general availability of the Atom 1.14 open-source and multiplatform hackable text editor for all supported platforms, including GNU/Linux, macOS, and Microsoft Windows.

    Launched exactly one month after the release of Atom 1.13, the new Atom 1.14 release does not appear to be a major milestone, as it only adds 64-bit installation support for Microsoft Windows operating systems, improved MRU tab traversal with a bunch of fixes, as well as large file performance across all platforms.

  • Why I Swapped VLC for MPV

    In fact, if I were to you all what video player you use on Ubuntu I’d be cowered by the collective cry of ‘VLC’!

    And quite right too. VLC is open-source, obscenely powerful and plays dang well near everything you chuck at it,

Red Hat and Fedora

  • Red Hat IT Single Sign On(SSO) Runs on Red Hat Virtualization

    Red Hat is best known for Red Hat Enterprise Linux (RHEL) and for being a leader in driving open source development projects. In many cases, the upstream projects then become Red Hat products that provide enterprise functionality elsewhere in the stack.

  • Red Hat Enterprise Linux Across Architectures: Everything Works Out of the Box

    Since the Red Hat Enterprise Linux Server for ARM Development Preview 7.3 became available I’ve been wanting to try it out to see how the existing code for x86_64 systems works on the 64-bit ARM architecture (a.k.a. aarch64).

    Going in, I was a bit apprehensive that some kind of heavy lifting would be needed to get things working on the ARM platform. My experience with cross-architecture ports with other distros (before I joined Red Hat) indicated going through dependency hell as I frantically tried to find equivalent packages for the ARM architecture. Needless to say, most of these porting exercises ended with massive amounts of productivity loss and potential security exposures as I downloaded packages from unknown sources, all the time hoping one of them would work.

  • NethServer 7 Server/Network-Focused Linux OS Released

    Last week, we have had a new Walkie Talkie app added to the Tizen Store, something a little different and a little fun, created by developer SomyaC. A walkie-talkie (more formally known as a Handheld Transceiver, or HT) is a hand- held, portable, two-way radio transceiver that lets you communicate directly between both handsets.

  • Udacity open sources its self-driving car simulator for anyone to use

    Self-driving cars require self-driving car software, and Udacity’s helping to feed that need with its nanodegree program in the field. Now, the online education company is also making available its self-driving car simulator via open source license, allowing anyone with a working knowledge of Unity to gab the assets, load its preexisting scenes and create their own tracks for virtual testing.

    If you weren’t already aware, a lot of the ‘education’ of self-driving vehicle software happens in virtual environments, since it’s still relatively expensive to build an actual self-driving test vehicle, and a bit complicated on the regulatory side to find somewhere willing to let you test in real-world conditions – plus you have to prove you can do so with a reasonable expectation of safety. That’s a steep hurdle for tinkerers working independently, and for companies just starting out.

  • Open source vs. COTS: 8 integration considerations

    Nothing is moving faster to the top of IT wish lists than hybrid integration platforms. They offer agencies the ability to use application programming interfaces to integrate on-premises, cloud and mobile applications. However, IT managers face a critical decision when it comes to choosing between an open-source or commercial-off-the-shelf enterprise service bus (ESB) for integration to support that hybrid environment. Below are eight considerations for deciding which digital initiative to implement.

  • The benefits of tracking issues publicly

    A public issue tracker is a vital communication tool for an open organization, because there's no better way to be transparent and inclusive than to conduct your work in public channels. So let's explore some best practices for using an issue tracker in an open organization.

    Before we start, though, let's define what we mean by "issue tracker." Simply put, an issue tracker is a shared to-do list. Think of scribbling a quick list of errands to run: buy bread, mail package, drop off library books. As you drive around town, it feels good to cross each item off your list. Now scale that up to the work you have to do in your organization, and add in a healthy dose of software-enabled collaboration. You've got an issue tracker!

  • 4 must-read books for open source career seekers

    Finding a good job can be stressful and finding your dream job even more so. Even in the open source world, with its many opportunities for making a name for yourself by volunteering, it takes effort to make the connection between what you have to offer as a job seeker and what employers are looking for in an employee. One thing that can help set you apart from other applicants is having a solid understanding of yourself and what you bring to the table.

  • The most popular JavaScript front-end tools

    Choosing a development tool based on its popularity isn’t a bad idea. Popular tools are usually more stable, and they often have more resources and community support than less popular tools. Developer satisfaction is another key indicator of a good tool, and for the JavaScript ecosystem, I'm going to show you some significant research on both of these criteria.

    The list that follows contains all of the main tooling categories for a modern JavaScript developer. It includes the most popular tools for each category according to developer popularity and user satisfaction.

  • Netflix Open Sources a Slack Bot for Tracking GitHub Repositories

    Not many organizations have the technology expertise that Netflix has, and it may come as a surprise to some people to learn that the company regularly open sources key, tested and hardened tools that it has used for years. We've reported on Netflix open sourcing a series of interesting "Monkey" cloud tools as part of its "simian army," which it has deployed as a series of satellite utilities orbiting its central cloud platform.

  • Launching an Independent OpenNews Program

    At Mozilla, one of our essential roles is convener: working to identify, connect and support like-minded people who are building a healthier Internet.

    An early — and strong — example of that work is the OpenNews program. Six years ago, Mozilla and Knight Foundation created an initiative to combine open-source practices with journalism. Our aim: strengthen journalism on the open web, and empower newsroom developers, designers and data reporters across the globe.

    The program flourished. Since 2011, OpenNews has placed 33 fellows in 19 newsrooms, from BBC and NPR to La Nacion and the New York Times. It built a global community of more than 1,100 developers and reporters. It spawned the annual SRCCON conference, bolstered newsroom diversity and gave way to innovative newsgathering tools like Tabula. OpenNews has also played a key role in building the annual MozFest in London and Mozilla’s nascent leadership network initiative.

    Mozilla is immensely proud of OpenNews — and immensely grateful to the team behind its success. And today, we’re announcing that OpenNews is spinning out as an independent organization. Going forward, OpenNews — with the support of nonprofit fiscal partner Community Partners — will build on the success it achieved when incubated at Mozilla. OpenNews will continue to play an active role in MozFest and Mozilla’s leadership network.

  • What’s next for open-source Spark?

    A conference focused on a single open source project sounds like the sort of event that will feature a lone keynote speaker speaking to maybe 100 interested parties in a lecture hall at a local college. Spark Summit East was very much the opposite.

    A total of 1,503 people watched the five keynote speakers in a cavernous ballroom at the Hynes Convention Center lay out the future of Spark, the big data processing engine originally developed at the University of California – Berkeley by Matei Zaharia. Spark underlies huge data-driven applications being used by major players like Salesforce, Facebook, IBM and many others, helping organize, analyze, and surface specific grains of sand from beach-sized databases.

  • Cloudera and Intel Team on Accelerating Machine Learning Workloads

  • Thousands of WordPress websites defaced through patch failures

    Thousands of WordPress domains have been subject to attack through a severe content injection security flaw that many website operators have failed to protect themselves against.

    The security flaw, a zero-day vulnerability that affects the WordPress REST API, allows attackers to modify the content of posts or pages within a website backed by the WordPress content management system (CMS).

    As noted by cybersecurity firm Sucuri, one of the REST endpoints allows access via the API to view, edit, delete, and create posts.

I am constantly reminded of how powerful the *nix shell is...

Reddit - Fri, 2017-02-10 01:27

So today I was privileged with yet another reminder of just how incredibly useful the command line is.
I was helping out a friend with an old computer and we decided to just scrap the thing and recover whatever data we could on the hard drive. So I took it home and started going through stuff and dear God let me tell you, this was the worst I have EVER seen for disorganization. In the MyDocuments folder alone there were five (5!) "New Folder"s all with subdirectories and including yet more New Folder spaghetti! I am an absolute minimalist when it comes to organizing my files. I delete stuff I don't need, have everything carefully treed out and nothing out of place, so this was horrifying! I didn't want to go through all that!
Basically the only thing they wanted to save were the pictures, so I opened up my handy terminal and used find | mv to grab all the files ending in jpg, png, or any other format I could think of for pictures or video and stick it all in one folder. It automatically skipped files with the same name, so I deleted all those afterward. Then, having only 9786 pictures/videos to go through, I had 24.9 GB in that folder. Now, I don't have a USB drive larger than 24GB, so I decided I'd see if there was any way to find duplicate files with different names. Google was my friend and I ran across this article: https://www.linux.com/learn/how-sort-and-remove-duplicate-photos-linux
installed fdupes, read a tad of the man page, and fired it off! It worked like a charm and deleted 1796 files, bringing the total size of the folder to 18.9GB. Boom.

Just.... bash and all the free and private-made utilities for it are awesome. This isn't an isolated event and it certainly is neither the first nor the last time the power of the command line has amazed me. So, for any devs reading, thank you! This is how you make a real positive impact in people's lives. It's the little things that sometimes just mean so much. Now I nor anyone else has to go sort through pictures for hours!

Security of file transfers over the internet through linux systems

Reddit - Fri, 2017-02-10 01:14

Other than using ubuntu here and there, I am a total noob with linux.

Can somebody please explain to me.

Is it potentially more secure to transfer files over a network of linux computers. IE : from linux desktops to linux server to other linux desktops.

I was curious if a linux based EMR system could compete with all the windows based EMR systems in the healthcare industry.

Remix OS: Is This the Droid You Were Looking For?

LXer - Fri, 2017-02-10 00:32
Ever wanted to try Android on your PC but there weren’t any really usable projects? Now you can. Remix OS is an Android based operating system that’s designed to offer a full-fledged desktop PC-like experience. The developers have done a lot of  work to implement many desktop-centric features such as multi-window multi-tasking. It offers a very familiar interface inspired by Windows, so the learning curve is not that steep. If you have used Android before, you will find yourself at home.
