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.

Bring JavaScript to your Java enterprise with Vert.x

Wednesday 4th of April 2018 07:02:00 AM

If you are a Java programmer, chances are that you've either used JavaScript in the past or will in the near future. Not only is it one of the most popular (and useful) programming languages, understanding some of JavaScript's features could help you build the next uber-popular web application.

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.

Mozilla: Rust, Security, Things Gateway, Firefox and More

  • Rust pattern: Precise closure capture clauses
    This is the second in a series of posts about Rust compiler errors. Each one will talk about a particular error that I got recently and try to explain (a) why I am getting it and (b) how I fixed it. The purpose of this series of posts is partly to explain Rust, but partly just to gain data for myself. I may also write posts about errors I’m not getting – basically places where I anticipated an error, and used a pattern to avoid it. I hope that after writing enough of these posts, I or others will be able to synthesize some of these facts to make intermediate Rust material, or perhaps to improve the language itself.

  • Mozilla publishes recommendations on government vulnerability disclosure in Europe
    As we’ve argued on many occasions, effective government vulnerability disclosure (GVD) review processes can greatly enhance cybersecurity for governments, citizens, and companies, and help mitigate risk in an ever-broadening cyber threat landscape. In Europe, the EU is currently discussing a new legislative proposal to enhance cybersecurity across the bloc, the so-called ‘EU Cybersecurity Act’. In that context, we’ve just published our policy recommendations for lawmakers, in which we call on the EU to seize the opportunity to set a global policy norm for government vulnerability disclosure.

    As you may already know, last Friday – April 20th – we held a new Testday event, for Firefox DevEdition 60 Beta 14. Thank you all for helping us make Mozilla a better place: gaby2300, micde, Jarrod Michell, Thomas Brooks.
  • Supporting Same-Site Cookies in Firefox 60
    Firefox 60 will introduce support for the same-site cookie attribute, which allows developers to gain more control over cookies. Since browsers will include cookies with every request to a website, most sites rely on this mechanism to determine whether users are logged in. Attackers can abuse the fact that cookies are automatically sent with every request to force a user to perform unwanted actions on the site where they are currently logged in. Such attacks, known as cross-site request forgeries (CSRF), allow attackers who control third-party code to perform fraudulent actions on the user’s behalf. Unfortunately current web architecture does not allow web applications to reliably distinguish between actions initiated by the user and those that are initiated by any of the third-party gadgets or scripts that they rely on.
  • Enterprise Policy Support in Firefox
    Last year, Mozilla ran a survey to find out top enterprise requirements for Firefox. Policy management (especially Windows Group Policy) was at the top of that list. For the past few months we’ve been working to build that support into Firefox in the form of a policy engine. The policy engine adds desktop configuration and customization features for enterprise users to Firefox. It works with any tool that wants to set policies including Windows Group Policy.
  • any.js
    Thanks to Ms2ger web-platform-tests is now even more awesome (not in the American sense). To avoid writing HTML boilerplate, web-platform-tests supports .window.js, .worker.js, and .any.js resources, for writing JavaScript that needs to run in a window, dedicated worker, or both at once. I very much recommend using these resource formats as they ease writing and reviewing tests and ensure APIs get tested across globals.
  • Alex Gibson: My fifth year working at Mozilla

Fedora Workstation 28 Coming Soon

  • Warming up for Fedora Workstation 28
    Been some time now since my last update on what is happening in Fedora Workstation and with current plans to release Fedora Workstation 28 in early May I thought this could be a good time to write something. As usual this is just a small subset of what the team has been doing and I always end up feeling a bit bad for not talking about the avalanche of general fixes and improvements the team adds to each release.
  • Fedora Workstation 28 Is Shaping Up To Be Another Terrific Update
    Fedora Workstation 28 is shaping up to be another compelling update for those that are fans of this bleeding-edge Red Hat sponsored Linux distribution. I've been running Fedora Workstation 28 snapshots on a few laptops and test machines here and am quite happy with how it's shaped up as another Fedora release that delivers not only the latest features, but doing so in a seemingly sane and stable manner: I haven't encountered any problems unlike some of the past notorious Fedora releases from years ago. Overall, I am quite excited for next month's Fedora 28 release and will be upgrading my main production system to it.

Configuring local storage in Linux with Stratis

Configuring local storage is something desktop Linux users do very infrequently—maybe only once, during installation. Linux storage tech moves slowly, and many storage tools used 20 years ago are still used regularly today. But some things have improved since then. Why aren't people taking advantage of these new capabilities? This article is about Stratis, a new project that aims to bring storage advances to all Linux users, from the simple laptop single SSD to a hundred-disk array. Linux has the capabilities, but its lack of an easy-to-use solution has hindered widespread adoption. Stratis's goal is to make Linux's advanced storage features accessible. Read more
