  • How You Can Help Localize Kubernetes Docs

    Last year we optimized the Kubernetes website for hosting multilingual content. Contributors responded by adding multiple new localizations: as of April 2019, Kubernetes docs are partially available in nine different languages, with six added in 2019 alone. You can see a list of available languages in the language selector at the top of each page.

  • Red Hat Summit 2019 session highlights: IT Automation and Management

    Management and automation technologies have always been instrumental to enterprise IT governance, however their importance grows as organizations grapple with increasing scale and complexity. Traditional solutions can often be unable to adapt to the needs of these rapidly changing hybrid cloud environments and organizations can acquire new tools to help address these challenges. Cloud-ready, agentless management and automation solutions can help standardize processes, accelerate IT service delivery, and more effectively manage infrastructure for compliance with policy-driven IT.

  • Harvey Available As Flatpak App

    WCAG stands for Web Content Accessibility Guidelines. Its role is to keep the website accessible to everyone. There are three levels; namely A, AA, and AAA.

    ​The further the level, the harder it becomes to design your website ie., A guideline is much easier than AA and AAA, again AA is easier than AAA but more difficulty in implementation compared to A. But that doesn't mean it's compulsory for your website to be WCAG compliant.

    This example is not uncommon in today’s enterprise IT world. And as of now there isn’t one clear solution, but that is not to say there isn’t one coming. While multicloud is a growing trend, we could eventually see services beyond multicloud that better meet the needs of end users. Some elements of these services are already starting to appear in limited practice today, but we can expect to see full solutions emerge as the next logical step in cloud evolution as more and more enterprises run into multicloud challenges.

  • Intel Iris Gallium3D Picks Up Conservative Rasterization Support

    On top of Intel's new open-source OpenGL driver seeing some hefty performance optimizations, the Iris Gallium3D driver has picked up another OpenGL extension ahead of the Mesa 19.1 branching. 

    Iris Gallium3D now supports INTEL_conservative_rasterization alongside the existing support in the i965 driver. INTEL_conservative_rasterization is the several year old Intel extension for seeing if all fragments are at least partially covered by a polygon rather than the default rasterization mode of including fragments with at least one sample covered by a polygon.

  • How do you say SUSE?

    SUSECON 2019 has come and gone and was definitely one for the books. Whether you were able to attend the event in person or not, you can still view plenty of videos and content that was shared at the event.
    One of my favorite videos from the week was “How do you say SUSE” -which comically reminded attendees how to properly say “SUSE.” Don’t quite know exactly how to pronounce SUSE? We’ve got you covered….Broadway musical style.
    The keynote videos from each day are not to be missed as well as the series of amazing music parody videos that have recently been created. One of the major take-a-ways this year was the recent announcement that as of March 15, not only did SUSE become an independent company, we are now the largest independent open source company in the industry.

  • In 2019, Most Linux Distributions Still Aren't Restricting Dmesg Access

    Going back to the late Linux 2.6 kernel days has been the CONFIG_DMESG_RESTRICT (or for the past number of years, renamed to CONFIG_SECURITY_DMESG_RESTRICT) Kconfig option to restrict access to dmesg in the name of security and not allowing unprivileged users from accessing this system log. While it's been brought up from time to time, Linux distributions are still generally allowing any user access to dmesg even though it may contain information that could help bad actors exploit the system.

    The primary motivation of CONFIG_SECURITY_DMESG_RESTRICT and an associated sysctl tunable as well (dmesg_restrict) is for restricting access to dmesg so unprivileged users can't see the syslog to avoid possible kernel memory address exposures among other potentially sensitive information that could be leaked about the kernel to help anyone trying to exploit the system. But even with these options being available for years, most Linux distributions leave dmesg open to any user.

  • Is Email Making Professors Stupid?

    So I'm going to talk a lot about it! With examples. But let's go through in chronological order.

  • Death by PowerPoint: the slide that killed seven people

    Edward Tufte’s full report makes for fascinating reading. Since being released in 1987 PowerPoint has grown exponentially to the point where it is now estimated than thirty million PowerPoint presentations are made every day. Yet, PowerPoint is blamed by academics for killing critical thought. Amazon’s CEO Jeff Bezos has banned it from meetings. Typing text on a screen and reading it out loud does not count as teaching. An audience reading text off the screen does not count as learning. Imagine if the engineers had put up a slide with just: “foam strike more than 600 times bigger than test data.” Maybe NASA would have listened. Maybe they wouldn’t have attempted re-entry. Next time you’re asked to give a talk remember Columbia. Don’t just jump to your laptop and write out slides of text. Think about your message. Don’t let that message be lost amongst text. Death by PowerPoint is a real thing. Sometimes literally.

  • Newer isn't always better when performance is critical

    Some years before I formalised my engineering education, I was working as an instrument technician on a seismic survey vessel mapping an area off West Africa. These ships map the geology under the sea bed as the first stage of marine oil exploration. In full production, a single vessel will generate a revenue of several hundred thousand dollars a day. So you need to have a good excuse for when the recording system fails and you leave a hole in the survey coverage, especially when you have an ex-military Norwegian built like the proverbial Viking as party manager.

    The recording system was crashing; no error warnings, no smoke or fire. It just stopped recording. Repeatedly. The survey was looking like a cartoon Swiss cheese that had been attacked by hungry mice. What had changed? To save money the company had developed its own recording system, replacing Old Faithful with New Unreliable. I had my reservations when the prototype was tested in parallel with Old Faithful leading to my tearing out the connection between the two systems with under a minute to the start of a production line to go. I was younger then and could handle the excitement.

  • Minikube: 5 ways IT teams can use it

    As far as tool names go, Minikube is a pretty good reflection of what it does: It takes the vast cloud-scale of Kubernetes and shrinks it down so that it fits on your laptop.

    Don’t mistake that for a lack of power or functionality, though: You can do plenty with Minikube. And while developers, DevOps engineers, and the like might be the most likely to run it on a regular basis, IT leaders and the C-suite can use it, too. That’s part of the beauty.

    “With just a few installation commands, anyone can have a fully functioning Kubernetes cluster, ready for learning or supporting development efforts,” says Chris Ciborowski, CEO and cofounder at Nebulaworks.

  • Altered, a sweet looking puzzle game where you're part of the puzzle is coming to Linux

    Releasing sometime this Summer, Altered looks like a rather sweet take on the puzzle genre as you're a block that forms part of a puzzle.

    The developer, Glitchheart, describes it as a "meditative" puzzle game that mixes difficult puzzles in with a "soothing atmosphere". The description made me chuckle a little, as you can make it seem as soothing as you want but if the puzzles really do get difficult you can't stop players getting frustrated. Still, solving puzzles doesn't need to make you sweat which is more the point here as it seems there's no set time limits and no dangers.

  • 9 Useful PDF Manipulation Tools

    Portable Document Format (PDF) is a file format created by Adobe Systems in 1993 for document exchange. The format includes a subset of the PostScript page description programming language, a font-embedding system, and a structural storage system.

    Over the years PDF has become an extremely important file format. If you want to create documents that can be viewed under all major operating systems, PDF is the ticket, as it maintains the overall look and feel of documents regardless of what platform they are viewed under.

    There is a large range of PDF-related software available with many different applications available that can both output to and open files. Many open source software save documents to this format such as LibreOffice and GIMP.

    The purpose of this Group Test is to highlight high quality small tools that are designed to manipulate PDF files. We are not considering PDF editors, PDF viewers, tools that add an OCR layer to PDF files here. This is because these categories are covered by other legendary Group Tests.

  • Blender short film, new license for Chef, ethics in open source, and more news

The character and asset files for the film are available from Blender Cloud, and tutorials, walkthroughs, and other instructional material are coming soon.

  • 6 alternatives to OpsGenie for managing monitoring alerts

    Now, if an issue comes up with any of this company's products, the response team should act before the customer (and company) experiences negative effects. There won’t be much of a problem if the response team is immediately there to jump on the issue, but in case they are not, someone from the response team should notify them in some way to reduce the diameter of functional or possible financial losses.

    Here's the problem. People are not able to notice and respond to issues all the time. If you send the response team an email or text message, there is a probability that no one on the team will see it before the issue causes significant financial loss. Also, the response team might already be receiving so many email alerts that even if they are available, they may find it difficult to spot the high-impact issues among the smaller ones. In this situation, you should send someone from the response team a distinct alert, such as making a phone call or messaging a pager. However, if you decide to call, you need to know who is actually available, otherwise you might have to call multiple people until you find the response team member who is ready to jump on a ringing phone at that very moment, which can take even longer if your call is at an odd time for their location.

    Instead, what you need is a tool that not only monitors your systems but also intelligently manages the alert process for the quickest results possible. A popular commercial option is OpsGenie, and in this article, we will talk about open source alternatives to this proprietary option.

  • An eBPF overview, part 2: Machine & bytecode

    In our first article we introduced the eBPF VM, its intentional design limitations and how to interact with it from a userspace process. If you haven't yet read it, you should probably do so before continuing because starting directly with machine and bytecode specifics can be hard without a proper introduction. If in doubt, see the flowchart at the beginning of part 1.

    The second part of this series takes a more in-depth look at the eBPF VM and program studied in the first part. Having this low level knowledge is not mandatory but can be a very useful foundation for the rest of the series where we examine higher level tools built on top of these mechanisms.

  • Can schools be agile?

    Not surprisingly, a go-to resource I recommend to any school wanting to begin or accelerate this process is The Open Organization by Jim Whitehurst. Not only does the book provide a window into how educators can create more open, inclusive leadership structures—where mutual respect enables nimble decisions to be made per real-time data—but it does so in language easily adaptable to the rather strange lexicon that's second nature to educators. Open organization thinking provides pragmatic ways any organization can empower members to be more open: sharing ideas and resources, embracing a culture of collaborative participation as a top priority, developing an innovation mindset through rapid prototyping, valuing ideas based on merit rather than the rank of the person proposing them, and building a strong sense of community that's baked into the organization's DNA. Such an open organization crowd-sources ideas from both inside and outside its formal structure and creates the type of environment that enables localized, student-centered innovations to thrive.

  • The Challenges Facing Privacy Apps

    When we talk about privacy as a concept, we tend to drill into the benefits of privacy and the crucial role that it plays in our lives as individuals. In aggregate, privacy extends its role to protect fundamental freedoms that we all agree are pillars to a free and happy society.

    What we don’t talk about is the challenges that privacy apps face, and how often tools are not designed to fulfill the needs of the needs of the end user.

    [...]

    Using software that is open source is a critical piece of the puzzle, because this allows peer review to verify that the developer isn’t collecting unnecessary data to make the app or service work, and that the developers have considered all of the external privacy threats.

    If the software isn’t open source, there’s no way to verify this. You have to implicitly trust that the developer doesn’t want to grab your data for money, which is always in their interest to do. You are hoping that the developer is principled enough to resist the urge to make more money off of you. This is an even greater concern when the application is free. You have to consider how, if not through your data, is the app developer making money?
