  • Not your BASIC web experience: Creative for Command Line Heroes Season 3 Episode 2

    Last week, we introduced this series with an overview of Command Line Heroes’ artwork. We hope you enjoyed reading about the details in the images for our first episode of season 3 about Python. Now, we’ll briefly cover how our web designers work to bring that artwork to you in its many forms—and we uncover the secrets of Episode 2: Learning the BASICs.

    Are there considerations beyond the initial design to take into account when putting the artwork online?
    Rachel Ertel, UX Lead: Considerations outside of the initial visual design are largely based on user experience. These include making sure the page’s load time is quick, to thinking through the way that the user would interact with copy, graphics, and actionable links. We want to make sure that the user comes to the right information at the right time, and that the process of getting where they want to go requires minimum effort and provides maximum reward.

  • Enhancing availability of SAP deployments with Red Hat Enterprise Linux 7 for SAP Solutions

    In August 2019, we announced the general availability of Red Hat Enterprise Linux (RHEL) 7.7, the latest update to the stable and production-ready RHEL 7 platform. RHEL 7 helps customers meet the modern datacenter demands as well as the next-generation IT requirements of existing and new SAP workloads. On top of that, RHEL 7 for SAP Solutions includes additional capabilities to support SAP Applications across the hybrid cloud, from bare-metal servers to public cloud instances, all on a standard, flexible and scalable operating system platform.

    Both RHEL 7.7 and RHEL 7.6 for SAP Solutions bring new features and enhancements1 to bear that can help streamline operations through improved availability and reduced operating costs. RHEL 7.6 for SAP Solutions is validated and supported for use with SAP HANA on Intel x86_64 and IBM Power 8. Corresponding validation for SAP HANA on RHEL 7.7 is planned. Other SAP applications and database products, like SAP NetWeaver or SAP ASE may adopt and benefit from RHEL 7.7 features right away. Please consult SAP Note 2369910 and 2235581 for the latest information about validated releases and support by SAP.

  • Advanced Ansible variables in Satellite

    Satellite 6.6 beta was released recently, and contains a number of improvements related to Ansible variables. Ansible variables can be used to customize the behavior of Ansible roles. For example, an Ansible role could be configured to install whatever package is specified in an Ansible variable. From Satellite, we can set the value of the Ansible variable so that the package we want is installed by the role.

    Satellite 6.4 introduced the ability to run Ansible roles on Satellite clients, and allowed for parameters to be defined that could be accessed from within the Ansible roles as variables. However, there were a couple limitations to how Ansible variables were supported in Satellite: only string variables were supported, and the Satellite administrator had to review the Ansible role to discover the variable names that should be defined as parameters within Satellite.

  • Fight for the planet: Building an open platform and open culture at Greenpeace

    Few organizations know this better than Greenpeace. For nearly 50 years, the non-profit has been campaigning for a greener and more peaceful future.

    But in 2015, Greenpeace found itself at a crossroads. To address the climate emergency, Greenpeace knew it needed to shift its organizational culture.

  • Brief on Behalf of Amicus Curiae Open Source Hardware Association in Curver Luxembourg, SARL v. Home Expressions Inc., No. 18-2214 (Fed. Cir.)

    Curver Luxembourg, SARL v. Home Expressions Inc. is a case of first impression for the Court of Appeals for the Federal Circuit. The question on appeal is whether a design patent’s scope is tied to the article of manufacture disclosed in the patent. In this amicus brief, the Open Source Hardware Association (“OSHWA”) explains the potential effects on open source hardware development, and design practice generally, of untethering design patent protection from the article of manufacture disclosed in the patent. A large percentage of open-source hardware combines both ornamental and functional elements, and industrial design routinely involves applying design concepts from disparate fields in novel ways. To engage in this practice, open-source hardware designers need to know the universe of available source material and its limits. Further, understanding the licensing requirements of open-source hardware begins with understanding how the elements that make up that hardware may or may not be protected by existing law. Accordingly, while many creators of open-source hardware do not seek patent protection for their own creations, an understandable scope of design patent protection is nonetheless essential to their ability to collaborate with other innovators and innovate lawfully. The brief argues that the District Court in the case—and every district court that has considered the issue—correctly anchored the patented design to the article of manufacture when construing the patent. The brief explains that anchoring the patented design to the disclosed article of manufacture is the best approach, for several reasons. Connecting the patented design to the disclosed article of manufacture calibrates the scope of design patent protection to the patentee’s contribution over the prior art. It avoids encumbering the novel and nonobvious application of prior designs to new articles of manufacture, a fundamental and inventive practice of industrial design. It aligns the scope of design patent protection with its purpose: encouraging the inventive application of a design to an article of manufacture. This balances protection for innovative designs with later innovators’ interest in developing future designs. Finally, anchoring the patented design to the disclosed article of manufacture helps fulfill design patent law’s notice function by clarifying the scope of protection.

  • Gallium3D's Mesa State Tracker Sees "Mega Cleanup" For NIR In Mesa 19.3

    AMD developer Marek Olšák has landed a "mega cleanup" to the Gallium3D Mesa state tracker code around its NIR intermediate representation handling. As part of getting the NIR support in good enough shape for default usage by the RadeonSI driver, Marek has been working on a number of clean-ups involving the common Gallium / Mesa state tracker code for NIR.

  • AMDGPU DC Looks To Have PSR Squared Away - Power-Savings For Newer AMD Laptops

    It looks like as soon as Linux 5.5 is where the AMDGPU kernel driver could be ready with Panel Self Refresh (PSR) support for enabling this power-savings feature on newer AMD laptops. While Intel's Linux driver stack has been supporting Panel Self Refresh for years, the AMD support in their open-source Linux driver code has been a long time coming. We've seen them working towards the support since Raven Ridge and now it appears the groundwork has been laid and they are ready to flip it on within the Display Core "DC" code.

    Computing with data whose form is not the most convenient way to be manipulated, like is often the case in unstructured binary data, requires performing a preliminary step that transforms the data into a more convenient representation, usually featuring a higher level of abstraction. This step is known in computer jargon as unmarshalling, when the data is fetch from some storage or transmission media or, more generally, decoding. Once the computation has been performed, the result should be transformed back to the low-level representation to be stored or transmitted. This is performed in a closing step known as marshalling or, more generally, encoding. Consider the following C program whose purpose is to read a 32-bit signed integer from a byte-oriented storage media at a given offset, multiply it by two, and store the result at the same offset.

  • Android NDK r21 moves to beta

    Android announced that NDK r21 is now in beta. Android NDK is a toolset for implementing parts of an app in native code. The release — which is the first long term support release — includes improved defaults for better security and performance. One of the key features in the release is an update to GNU Make to version 4.2, which provides a number of bug fixes, and enables ‘–output-sync’ to avoid interleaving output with error messages, the team explained. This is enabled by default with ndk-build. Additionally, GDB, the GNU project debugger, has been updated to version 8.3, which includes fixes for debugging modern Intel CPUs.

  • What is the history behind C Programming and Unix?

    If you think C programming and Unix are unrelated, then you are making a big mistake. Back in the 1970s and 1980s, if the Unix engineers at Bell Labs had decided to use another programming language instead of C to develop a new version of Unix, then we would be talking about that language today. The relationship between the two is simple; Unix is the first operating system that is implemented with a high-level C programming language, got its fame and power from Unix. Of course, our statement about C being a high-level programming language is not true in today’s world. This article is an excerpt from the book Extreme C by Kamran Amini. Kamran teaches you to use C’s power. Apply object-oriented design principles to your procedural C code. You will gain new insight into algorithm design, functions, and structures. You’ll also understand how C works with UNIX, how to implement OO principles in C, and what multiprocessing is.

    “With the OpenStack market forecasted to grow to $7.7 billion by 2022 according to 451 research, the demand for Certified OpenStack Administrators is clearly strong and set to continue growing for many years to come,” said Mark Collier, COO of the OpenStack Foundation. “We are excited to collaborate with Mirantis, who has stepped up to provide the resources needed to manage the COA, including the administration of the vendor-neutral OpenStack certification exam.”

  • How to use containers with an eye on security

    Containers are all the rage. With good reason. With containers, your company’s apps and service deployments become considerably more agile, more reliable, and even more secure. This is true for software development companies (who develop apps and services for other businesses), as well as companies looking to roll out web-based and mobile applications with an unheard of speed and reliability. But with any new technology, comes hurdles. One of the biggest hurdles for any business is security. Data breaches have become rampant and it’s on the shoulders of every company to do everything in their power to make sure they are rolling out technology that is as secure as possible. This idea should certainly be applied to containers. But what can you do to use containers security? Fortunately, there are a few steps that you can take from the very beginning.

  • Pensando Systems Exits Stealth Mode With Plans To Take On Amazon AWS

    While normally we don't cover hardware start-ups on Phoronix, Pensando Systems has just exited stealth and given their focus will be heavily involved with Linux and in fact already have their first kernel driver mainlined. After announcing a $145 million (USD) Series-C round, Pensando Systems exited "stealth" and revealed the first details of what they are trying to achieve with this company led by many ex-Cisco staff. [...] Pensando has been on our radar since as I wrote about last month when they were just a stealth networking startup they already upstreamed their first Linux kernel driver. In the Linux 5.4 kernel is a Pensando "Ionic" driver for a family of network adapters. In this week's press release, Pensando didn't specifically call out Ionic but presumably is the backbone to their hardware. Now that they are beginning to talk about their ambitions, hopefully we see more Linux kernel patches from them soon.
