Graphics: Screen Tearing, Wayland Alpha Compositing Protocol, AMDGPU

Graphics/Benchmarks
  • What Is Screen Tearing and How to Get Rid of It on Linux

    Unfortunately for Linux fans, screen tearing is, and has been, a persistent annoyance that doesn’t seem to be going anywhere. There are a couple of factors enabling the longevity of the screen tearing issue.

    First, and probably most obviously, is the dated, broken, and bloated X server. Even with the progress of Wayland, X is here to stay for the immediate future. Next is the strange and inconsistent graphics driver picture. One of the biggest offenders in causing screen tearing is also the most popular GPU manufacturer on Linux, NVIDIA. Throw in different desktop environments with their own display settings and compositors, and you have a real mess.

    These methods will hopefully eliminate screen tearing in most situations, but it’s impossible to provide a one-size-fits-all solution, thanks to the amount of variables involved. Try what applies to your system, and keep in mind that there might be new factors involved.

  • Collabora Revives Work On Alpha Compositing Protocol For Wayland

    Collabora's Scott Anderson has revived work on the alpha compositing protocol for Wayland, which is based upon the work done by Google on this functionality for Chromium on Wayland.

    The Wayland Alpha Compositing Protocol is intended to control the alpha compositing and blending of surface contents within a Wayland environment. This experimental protocol allows for advanced blending and alpha operations on Wayland surfaces (wl_surface) and Google's work on it dates back at least two years.

  • Radeon Linux Driver Preparing Adaptive Backlight Management (ABM)

    The "AMDGPU" Radeon Linux kernel graphics driver is preparing support for "Adaptive Backlight Management" as a backlight power-savings feature for laptops.

    Adaptive Backlight Management reduces the backlight level in an effort to save power but increases the pixel contrast and luminance to improve image quality and readability under the lower light condition.

Meet TiDB: An open source NewSQL database

OSS

As businesses adopt cloud-native architectures, conversations will naturally lead to what we can do to make the database horizontally scalable. The answer will likely be to take a closer look at TiDB.

TiDB is an open source NewSQL database released under the Apache 2.0 License. Because it speaks the MySQL protocol, your existing applications will be able to connect to it using any MySQL connector, and most SQL functionality remains identical (joins, subqueries, transactions, etc.).

Step under the covers, however, and there are differences. If your architecture is based on MySQL with Read Replicas, you'll see things work a little bit differently with TiDB. In this post, I'll go through the top five key differences I've found between TiDB and MySQL.

Is your startup built on open source? 9 tips for getting started

Filed under
OSS

When I started Gluu in 2009, I had no idea how difficult it would be to start an open source software company. Using the open source development methodology seemed like a good idea, especially for infrastructure software based on protocols defined by open standards. By nature, entrepreneurs are optimistic—we underestimate the difficulty of starting a business. However, Gluu was my fourth business, so I thought I knew what I was in for. But I was in for a surprise!

Every business is unique. One of the challenges of serial entrepreneurship is that a truth that was core to the success of a previous business may be incorrect in your next business. Building a business around open source forced me to change my plan. How to find the right team members, how to price our offering, how to market our product—all of these aspects of starting a business (and more) were impacted by the open source mission and required an adjustment from my previous experience.

A few years ago, we started to question whether Gluu was pursuing the right business model. The business was growing, but not as fast as we would have liked.

An Everyday Linux User Review Of Elementary OS 5.0 Juno

Filed under
Reviews

Elementary OS is currently riding high in the Distrowatch rankings and it has been a while since my last review so I thought it was high time I took another look.

The tag line at the top of the Elementary OS website reads as “The fast, open and privacy respecting replacement for Windows and macOS”.

In this review I am going to examine this claim in depth as well as other claims such as “Apps you need, without the ones you don’t”. The website states that the applications have been carefully considered to cater for your everyday needs so you can spend more time using your computer and less time cleaning up bloatware.

Without further ado lets separate the fact from the fiction and explore Elementary OS with a virtual magnifying glass befitting a well known sleuth. After all it is “Elementary” my dear Watson. (Sorry, couldn’t resist).

  • OpenStack Expands With New Projects, Canonical’s CEO Is Not Thrilled About It

    For those who have been paying attention (and SDxCentral has been), the OpenStack Foundation has been expanding its scope beyond the basic compute, storage, and networking sub-projects of its cloud infrastructure software. Today at the OpenStack Summit in Berlin the group made it official, announcing that it will host new open source projects with a new governance framework.

    The OpenStack Foundation board approved the governance framework to incubate new pilot projects that are relevant to the open infrastructure community. As part of this new framework, the first four pilot projects are Kata Containers, Airship, Zuul, and StarlingX. All of these projects have been previously announced.

  • Open source is growing up – and here’s how

    If you’re among those who still think that open source is just for hobbyists and academics, think again. Open source is mature now, both as a concept and as tools for building enterprise IT, and we have two major shifts in understanding to thank for that.

    The first key change is that there’s a much more mature understanding now of how the layers of IT architecture relate to each other – of what fits where, in other words. Instead of trying to do too much, adding in every feature or capability that might be related, open source projects have become more focused.

    For example, instead of misunderstanding them as rivals, we can now see OpenStack and Kubernetes for what they are. The former is an infrastructure layer, upon which you can run platform layers such as the latter.

  • Open-source and cloud-native, Kubernetes paves the way for new companies to bring DevOps to data

    With less than two months left, 2018 is poised to go down in tech history as the coming of age for open-source software.

    Need evidence? Over the past 10 months, notable open-source enterprises MuleSoft Inc., Magento Inc., GitHub Inc. and Red Hat Inc. have been purchased for a combined $50 billion.

    Yet before jumping on the open-source bandwagon, observers would be wise to keep in mind that these technologies still depend on a sizable community of contributors to keep innovation fresh, and monetization of many open-source projects remains a struggle. So what is all the fuss about?

  • Red Hat OpenStack Platform 14 coming soon with tighter Kubernetes integration

    Today, Red Hat has announced Red Hat OpenStack Platform 14, saying it will become available in the coming weeks. The firm says that the latest version, which is built on the OpenStack “Rocky” community release, more tightly integrates with the Red Hat OpenShift Container Platform which gives admins full control over their Kubernetes environments.

  • Red Hat commits to Openstack for 'at least' 10 years

    While Red Hat understandably wouldn't discuss anything to do with the IBM mega-acquisition - for regulatory reasons - director of product management James Labocki and senior director for product management at Openstack Nick Barcet confirmed Red Hat's commitment to Openstack for at least the next "10 years".

    The open source giant today announced Openstack Platform 14, which Barcet said aimed to make Openstack a better platform to run container orchestration system Kubernetes on, while also helping to better manage the deployment of Red Hat's container platform OpenShift on bare metal, as well as easing the integration of OpenShift and Openstack at the networking and storage layer. This, says Barcet, is a landmark move for Red Hat because it is part of a new strategy to focus on its whole portfolio as a single entity rather than individual products.

Moz/FF
  • Mozilla shares how AV1, the new the open source royalty-free video codec, works

    Last month, Nathan Egge, a Senior Research Engineer at Mozilla explained technical details behind AV1 in depth at the Mile High Video Workshop in Denver. AV1 is a new open source royalty-free video codec that promises to help companies and individuals transmit high-quality video over the internet efficiently.

    AV1 is developed by the Alliance for Open Media (AOMedia), an association of firms from the semiconductor industry, video on demand providers, and web browser developers, founded in 2015. Mozilla joined AOMedia as a founding member.

    AV1 was created for a broad set of industry use cases such as video on demand/streaming, video conferencing, screen sharing, video game streaming, and broadcast. It is widely supported and adopted and gives at least 30% better than current generation video codecs.

  • Private by Design: How we built Firefox Sync

    Firefox Sync lets you share your bookmarks, browsing history, passwords and other browser data between different devices, and send tabs from one device to another. It’s a feature that millions of our users take advantage of to streamline their lives and how they interact with the web.

    But on an Internet where sharing your data with a provider is the norm, we think it’s important to highlight the privacy aspects of Firefox Sync.

    Firefox Sync by default protects all your synced data so Mozilla can’t read it. We built Sync this way because we put user privacy first. In this post, we take a closer look at some of the technical design choices we made and why.

A total of 31 organizations have come together to launch the Ceph Foundation including industries like ARM, Intel, Harvard and many more. The foundation aims to bring industry members together to support the Ceph open source community.

    [...]

    The Ceph Foundation will provide an open, collaborative, and neutral home for project stakeholders to coordinate their development and community investments in the Ceph ecosystem.

  • Linux Foundation Launches Open Source Ceph Storage Group

    Open source storage gets a boost today as the Linux Foundation launches the Ceph Foundation with more than 30 members including China Mobile, DigitalOcean, Intel, OVH, and Red Hat.

    The Ceph project is a unified distributed storage system providing applications with object, block, and file system interfaces. It was co-founded more than a decade ago by Sage Weil, who is now chief architect at Red Hat for Ceph, and University of California, Santa Cruz professor Carlos Maltzahn. A whole team of storage engineers now manage and maintain the open source code.

  • OPNFV Gambia — Doing what we do best while advancing cloud native

    Today, the OPNFV community is pleased to announce the availability of Gambia, our seventh platform release! I am extremely proud of the way the community rallied together to make this happen and provide the industry with another integrated reference platform for accelerating their NFV deployments.

    At a high level, Gambia represents our first step towards continuous delivery (CD) and deepens our work in cloud native, while also advancing our core capabilities in testing and integration, and the development of carrier-grade features by working upstream. As an open source pioneer in NFV, it’s amazing to see the evolution of the project to meet the needs of a quickly changing technology landscape.

  • HelpSystems Gets Into JAMS for Scheduling

    HelpSystems yesterday announced the acquisition of MVP Systems Software, the Connecticut-based developer of the JAMS workload management and scheduling software. While JAMS supported IBM i, HelpSystems will count on the product to deliver capabilities primarily in the open systems realm, with cloud possibilities looming in the future.

    The acquisition came together as the result of mutual respect that HelpSystems and MVP Systems Software had for each other, says Kate Bolseth, general manager of cross platform products at HelpSystems.

  • What's the reality of OpenStack and public cloud?

    My colleague, Margaret Dawson, spends a lot of time talking with customers. And in those conversations, questions about cloud and OpenStack invariably come up. She shared this message a while back, during her keynote at the OpenStack Summit in Vancouver, and it still resonates. While public cloud looms large in many companies’ plans, OpenStack’s future looks bright in the hybrid cloud reality we see today -- and tomorrow.

    “Most of you, especially if you’ve been working on OpenStack for a while, hear ‘Game’s over. Why are we even still doing this? AWS has won, so let’s just put everything in the public cloud and call it a day.”

  • Impact of IBM-Red Hat Merger

    Recently, there have been numerous machine learning, and AI algorithms developed to achieve the desired output in a dynamic, efficient, and effective manner. However, in a real-time scenario, an individual algorithm has its own advantages and is restricted to certain limitations. These limitations can be minimized by integrating different algorithms to achieve the desired task. By capturing the insights into the integral approach, IBM has announced its acquisition of Red Hat technologies to enhance its cloud-based business services to its clients.

    In the past year, nearly a quarter of IBM overall revenue was achieved through the cloud service platform. But with an increase in competitors, the company was overshadowed by other cloud rivals such as Microsoft and Amazon. Ginni Rometty, CEO of IBM, stated that at present, only 20 percent of the companies are renting cloud services to cut costs; over 80 percent are still unlocking their business values and can shift their business applications to the hybrid cloud in the near future for data extraction and optimization.

Debian Packages To Eliminate Vendor-Specific Patches, Affecting Downstreams Like Ubuntu

Filed under
Debian

Debian packages have supported the concept of vendor-specific patches whereby when DPKG unpacks a source package on different operating systems / distributions (such as Debian vs. Ubuntu), different patches could be selectively applied. Ubuntu is one of the main benefactors of this feature while effective immediately these vendor-specific patches to source packages will be treated as a bug and will be unpermitted following the Debian 10 "Buster" release.

This vendor-specific patch behavior for DPKG is mainly to help downstreams of Debian such as Ubuntu (not to be confused with vendor-specific hardware patches, etc). This vendor-specific patching has been used where say Ubuntu wishes to make some customizations to a Debian package that are minor in nature or basic alterations, they could land the changes in upstream Debian as a vendor-specific patch that would then be applied to the source package when building on Ubuntu... But keeping the package unpatched on Debian, or vice-versa. It reduces the maintenance burden for those wanting to selectively make basic changes to a package without having to maintain multiple largely redundant packages.

A couple of weeks ago IBM announced its plan to buy Red Hat for $34 billion. Following that, experts started speculating that rival companies like Canonical and Suse would sell as well.

However, Canonical’s founder, Mark Shuttleworth, doesn’t seem to have any plans of selling the company — at least not in the near future. In an encounter with TechCrunch, he said, “I value my independence.”

One of the reasons behind this decision is that he doesn’t really need the money. But another big reason for not selling is his vision for Canonical and Ubuntu, which he would like to see through personally.
