The current state of Linux video editing 2018

Monday 9th of April 2018 07:02:00 AM

It's pretty well known that Linux is a big deal in modern movie making. Linux is the standard base, a literal industry standard for digital effects but, like all technology with momentum, it seems that the process of cutting footage still defaults mostly to a non-Linux platform. Slowly, however, as artists seek to simplify and consolidate the post-production pipeline, Linux video editing is gaining in popularity.

5 steps to building a cloud that meets your users' needs

Monday 9th of April 2018 07:01:00 AM

This article was co-written with Ian Tewksbury.

However you define it, a cloud is simply another tool for your users to perform their part of your organization's value stream. It can be easy when talking about any new paradigm or technology (the cloud is arguably both) to get distracted by the shiny newness of it. Conversations can quickly devolve into feature wish lists set off by a series of never-ending questions, all of which you probably have already considered:

Making cloud-native computing universal and sustainable

Sunday 8th of April 2018 07:00:00 AM

I’ve been fortunate to have the opportunity to build an open source foundation from scratch the last couple of years by serving as the founding executive director of the Cloud Native Computing Foundation (CNCF). Since late 2015, the foundation has grown to comprise more than 200 members worldwide and 18 innovative cloud-native projects.

13 Git tips for Git's 13th birthday

Saturday 7th of April 2018 07:00:00 AM

Git, the distributed revision-control system that's become the default tool for source code control in the open source world, turns 13 on April 7. One of the more frustrating things about using Git is how much you need to know to use it effectively. This can also be one of the more awesome things about using Git, because there's nothing quite like discovering a new tip or trick that can streamline or improve your workflow.

Mainstream academia embraces open source hardware

Friday 6th of April 2018 07:02:00 AM

Twenty years ago, even staunch proponents of free and open source software like Richard Stallman questioned the social imperative for free hardware designs. Academics had barely started to consider the concept; the number of papers coming out annually on the topic were less than could be counted on someone's fingers.

Not anymore!

Goofy learns to fish: Why good documentation matters

Friday 6th of April 2018 07:01:00 AM

No matter what type of project you're working on, you can't expect users to fully understand it on their own. That's where documentation comes in. Docs can be anything from simple procedures to thorough user stories. Sure, a web UI can sometimes speak for itself (and the best ones do), but I'm sure you've seen tales of readers questioning basic UI paths or squirming about doing anything on the command line.

This is why creating documentation—even for the most basic of topics—is important for users.

Submitting my first patch to the Linux kernel

Friday 6th of April 2018 07:00:00 AM

I started using Linux three years ago while attending university, and I was fascinated to discover a different desktop environment. My professor introduced me to the Ubuntu operating system, and I decided to dual-boot it along with Windows on my laptop the same day.

How to find files in Linux

Thursday 5th of April 2018 07:03:00 AM

If you're a Windows user or a non-power-user of OSX, you probably use a GUI to find files. You may also find the interface limited, frustrating, or both, and have learned to excel at organizing things and remembering the exact order of your files. You can do that in Linux, too—but you don't have to.

Getting started with Vagrant

Thursday 5th of April 2018 07:02:00 AM

If you're like me, you probably have a "sandbox" somewhere, a place where you hack on whatever projects you're working on. Over time, the sandbox will get crufty and cluttered with bits and pieces of ideas, toolchain elements, code modules you aren't using, and other stuff you don't need. When you finish something, this can complicate your deployment, because you may be unsure of the actual dependencies of your project—you've had some tool in your sandbox for so long that you forget it must be installed.

How to create an impact map for teams

Thursday 5th of April 2018 07:01:00 AM

There are plenty of tools that can help you develop and implement great ideas—a user story workshop, story map, value proposition canvas, business model canvas, or even simply making a backlog of things to do. In this article, we will discuss a tool called impact mapping.

Impact mapping is a strategic planning technique designed to clearly communicate assumptions of your product or service’s interdependent, dynamic relationship with people, other projects, the supporting organization, and the wider community around them.

Who really owns an open project?

Thursday 5th of April 2018 07:00:00 AM

Differences in organizational design don't necessarily make some organizations better than others—just better suited to different purposes. Any style of organization must account for its models of ownership (the way tasks get delegated, assumed, executed) and responsibility (the way accountability for those tasks gets distributed and enforced). Conventional organizations and open organizations treat these issues differently, however, and those difference can be jarring for anyone hopping transitioning from one organizational model to another.

What the pandas Python data analysis library and SQL taught me about taking an average

Wednesday 4th of April 2018 07:03:00 AM

For Python developers who work primarily with data, it's hard not to find yourself constantly knee-deep in SQL and Python's open source data library, pandas. Despite how easy these tools have made it to manipulate and transform data—sometimes as concisely as one line of code—analysts still must always understand their data and what their code means. Even calculating something as simple as summary statistics can be prone to serious mistakes.

10 commands every Linux user should know

Tuesday 3rd of April 2018 07:02:00 AM

You may think you're new to Linux, but you're really not. There are 3.74 billion global internet users, and all of them use Linux in some way since Linux servers power 90% of the internet. Most modern routers run Linux or Unix, and the TOP500 supercomputers also rely on Linux. If you own an Android smartphone, your operating system is constructed from the Linux kernel.

In other words, Linux is everywhere.

Graphics: AMD, RADV, RadeonSI, Mesa 18.0.1

  • AMDGPU DRM Gets "GFXOFF" Patches To Turn Off Graphics Engine
    AMD's Huang Rui has posted a set of 20 patches providing "GFXOFF" support for the AMDGPU Direct Rendering Manager Linux kernel driver. GFXOFF is a new graphics processor feature that allows for powering off the graphics engine when it would otherwise be idle with no graphics workload. Obviously, this would equate to a potentially significant power savings with that engine being able to be shut-off.
  • RADV Driver Lands Support For Vulkan's New Descriptor Indexing Extension
    Earlier this month with the Vulkan 1.1.72 specification update was the new VK_EXT_descriptor_indexing extension that is quickly being well received by developers. The VK_EXT_descriptor_indexing extension allows for creating large descriptor sets made up of all their combined resources and selecting those resources via dynamic indexes in a shader.
  • RadeonSI Now Appears To Support "RX Vega M" With Intel Core CPUs
    One of the most common Linux hardware questions I've received dozens of times in the past few weeks alone has been over the support for "RX Vega M" Vega-based graphics processors found on select newer Intel Kabylake CPUs. It appears RadeonSI at least should now support these Radeon graphics on Intel CPUs.
  • mesa 18.0.1
  • Mesa 18.0.1 Released With A Number Of Fixes
    In addition to Mesa 17.3.9 being released today, Mesa 18.0.1 also rolled out the door as the first point release to last quarter's Mesa 18.0 series. Mesa 18.0.1 features improvements to its Meson build system support, several RADV Vulkan driver fixes, various fixes to the Gallium3D Nine (D3D9) state tracker, various Intel driver fixes, several core Mesa improvements, and then the other random smothering of fixes collected over the past few weeks.

Programming: nGraph Compiler, JavaScript Trademark, PyPI and Pip

  • Intel Opens Up nGraph Source Code For DNN Model Compiler
    Intel tonight announced they are open-sourcing their nGraph compiler code, which serves as a framework-neutral deep neural network model compiler. Intel claims with nGraph and Xeon Scalable hardware that researchers can obtain up to 10x performance improvements over previous TensorFlow integrations, as one example. Besides TensorFlow, nGraph also supports PyTorch, MXNet, Neon, Caffe2, and CNTK while also planning to support other frameworks moving forward.
  • Why it's finally time to give up on the name JavaScript
    An iOS developer has apparently received a cease and desist notice from Oracle over the use of the word "JavaScript" in the title of their app. The developer, Tyanya Software, shared the notice on perennial internet soapbox Reddit to seek advice on how to fight the order. [...] If user reviews are any indication, the app is not even particularly good, with reviewers stating things such as "Not ready for production," "Does not work as advertised," and "Waste of money, don't buy this." The last update to the app was in 2014, which the changelog notes was only an upgrade to add support for iOS 8. The app developer is at least honest about the intent behind the unwieldy name for the app, saying in a Reddit comment that "we game the App Store ranking by adding all the keywords to the app name." While Oracle has a duty to protect their trademarks, this type of legal bludgeoning underscores a historical problem that has been left unaddressed for too long: JavaScript is a terrible name for the thing being described. It has nothing to do with Java, an actual product developed by Sun (now owned by Oracle). JavaScript was developed at Mozilla, and the name was changed during beta releases of Netscape Navigator 2.0 from "LiveScript" to "JavaScript." It has, for some time, caused confusion among casual web users about the difference between Java and JavaScript. Given that ECMAScript is also a trademarked term, it seems best to revert to calling the language "LiveScript" to undercut trademark-related legal posturing. [...] Oracle declined to comment on this story.
  • New PyPI launched
    The new PyPI has been launched. Browser traffic and API calls (including "pip install") have been redirected from the old pypi.python.org to the new site. The old PyPI will shut down on April 30. LWN covered the new PyPI last week.
  • Pip 10.0 has been released
    The release of pip 10.0 has been announced. Some highlights of this release include the removal of Python 2.6 support, limited PEP 518 support (with more to come), a new "pip config" command, and other improvements.

Meltdown/PTI Mitigation Impact On BSDs vs. Linux

Besides the fresh BSD/Linux disk performance tests, some other tests I ran on various BSDs and Linux distributions this week was looking at the performance impact of Intel Meltdown CPU vulnerability mitigation on each of them, namely the performance impact of using kernel page-table isolation. On DragonFlyBSD 5.2, TrueOS 18.03, Ubuntu 16.04, Ubuntu 18.04, and Clear Linux I ran tests when the mitigation was enabled and then again when it was off for seeing the performance impact. Read more

Red Hat and Fedora Leftovers

  • Enterprise Node.js on OpenShift, April 19th, 12 p.m. EDT
    The next online DevNation Live Tech Talk is Thursday, April 19th at 12pm EDT. The topic is “Enterprise Node.js on Red Hat OpenShift” presented by Lance Ball, and hosted by Burr Sutter. The popularity of JavaScript on the front end and the JSON format for data has led to a “JavaScript Everywhere” movement with Node.js at the center. Node.js offers developers an event-driven, non-blocking I/O model that is perfect for high concurrency, low-latency applications that run across distributed devices. Its reactive architecture makes it an ideal technology for containerized microservices architectures you’ve been hearing so much about.
  • President to President with Luc Villeneuve, Red Hat Canada
    ITWC President Fawn Annan gets to the point with Red Hat’s general manager for Canada. Villeneuve speaks about building the open source technology firm in the country, the unique differences when dealing with the Quebec market, and how he fosters a positive culture in the workplace. Plus, he dishes on how his experience in journey hockey taught him how to build a successful sales team.
  • Be mindful of jumping into an open source project too soon: RedHat CTO
    Open source software has long been seen as a movement towards collaborative development. In a conversation with BusinessLine, Chris Wright, Vice-President & CTO at RedHat, talks about some of the challenges the open source community is facing and why it is important to set expectations right when it comes to promoting open source software. Edited excerpts:
  • DevOps Tool Market Global Manufacturers: Chef, Atlassian, Saltstac, Red Hat and Docker Inc.
  • Two sizzlers stock’s are not to be missed: Red Hat, Inc. (RHT), Navient Corporation (NAVI)
  • Fedora Community Blog: Fedora meetup at Pune – March 2018
    Long time we did not had any meetup at Pune, Maharashtra, India, so we decided to get started again. Details about this meetup are available at Fedora Wiki page. Planning for meetup started 1 month before. Initially Ompragash proposed to have meetup.com account for Fedora Pune to get more awareness. Later dropped this plan, since this is not only Fedora Pune level topic but applicable for all Fedora events.
  • Fedora 28 Beta – dnf system-upgrade
    Used DNF to remove duplicate rpms, reinstalled the new kernel and libwbclient, and corrected GNOME’s right-click behaviour, and all is well.
