Filed under
Graphics/Benchmarks

Last week I posted an article looking at the Relative Spectre/Meltdown Mitigation Costs On Windows vs. Linux. Today from a different system and using Windows Server 2016 rather than Windows 10 are some fresh benchmarks doing a similar comparison with different hardware and also looking at the Spectre and Meltdown mitigation performance impact again on Ubuntu 18.04 LTS and Clear Linux.

Red Hat looks beyond Linux

Red Hat

The Red Hat Linux distribution is turning 25 years old this week. What started as one of the earliest Linux distributions is now the most successful open-source company, and its success was a catalyst for others to follow its model. Today’s open-source world is very different from those heady days in the mid-1990s when Linux looked to be challenging Microsoft’s dominance on the desktop, but Red Hat is still going strong.

To put all of this into perspective, I sat down with the company’s current CEO (and former Delta Air Lines COO) Jim Whitehurst to talk about the past, present and future of the company, and open-source software in general. Whitehurst took the Red Hat CEO position 10 years ago, so while he wasn’t there in the earliest days, he definitely witnessed the evolution of open source in the enterprise, which is now more widespread than every.

  • “Top Notch” Android Phones Are Utterly Stupid And I Feel Sorry For Them

    I’m not going to dive deep and rant about all the “courageous” paths taken by Apple that I didn’t like. I’m not going to discuss why Apple ditched the 3.5mm headphone jack or why it chose to push proprietary connectors and standards. However, since this article is all about notches and Android device manufacturers are hellbent on copying Apple, changes brought in iPhone X can’t be ignored.

  • The ways of the GNOME people

    Hidden away in the farthest corner of the planet, its slopes covered in mist and darkness and its peaks lost in the clouds, stands the formidable Mount GNOME. Perched atop the mountain is a castle as menacing as the mountain itself – its towering walls made of stones as cold as death, and the wind howling through the courtyard like a dozen witches screaming for blood.

    Living inside the imposing blackness are a group of feral savages, of whom very little is known to the world outside. The deathly walls of the castle bear testimony to their skull-crushing barbarism, and their vile customs have laid waste to the surrounding slopes and valleys. Mortally fearful of invoking their mad wrath, no human traveller has dared to come near the vicinity of their territory. Shrouded in anonymity, they draw their name from the impregnable mountain that they inhabit – they are the GNOME people.

  • Leak Hunting and Mutter Hacking

    Last week, when I upgraded to GNOME 3.28, I was sad to notice an extremely annoying bug in Mutter/GNOME Shell: every once in a while, a micro-stuttering happened. This was in additions to another bug that was disappointing me for quite a while: the tiling/maximize/unmaximize animations were not working on Wayland too.

  • Best Content Management System

    Unless you've been living under a rock, you most certainly have heard of WordPress, one of the most popular blogging platforms around that also happens to be 100% open source. WordPress powers 27% of the web from personal to corporate to even government sites (Whitehouse.gov for one).

    In a 2008 interview, Linux Journal's Katherine Druckman asked WordPress founder Matt Mullenweg, "You frequently have reiterated your commitment to open-source ideals and GPL licensing. How has this commitment factored into the development of your company, Automattic? How do you use open-source technology to achieve your goals?"

  • FOSS Project Spotlight: CloudMapper, an AWS Visualization Tool

    When working with AWS, it's common to have a number of separate accounts run by different teams for different projects. Gaining an understanding of how those accounts are configured is best accomplished by visually displaying the resources of the account and how these resources can communicate. This complements a traditional asset inventory.

    Duo built CloudMapper to generate interactive network diagrams of AWS accounts and released it as open source on Github.

  • Could this $500 open-source printer be the RepRap of 3D bioprinters?

    Researchers from Adam Feinberg’s lab at Carnegie Mellon University have developed an open-source 3D bioprinter that can be built affordably using a modified desktop 3D printer. The large-volume extruder (LVE) component of the bioprinter can be 3D printed.

  • Carnegie Mellon University researchers publish designs for open-source 3D bioprinter

    Researchers at Carnegie Mellon University have developed an open-source, low-cost 3D bioprinter. They have published a paper in HardwareX with the complete instructions for the installation of a syringe-based large volume extruder (LVE) on a desktop FDM 3D printer.

    The LVE allows users to print artificial human tissues at a high resolution and scale. It is designed to print a range of materials, including biopolymers, hydrogels, pastes and epoxies.

    Adam Feinberg, one of the authors of the paper and a Biomedical Engineering Associate Professor at Carnegie Mellon, said “The LVE 3D bioprinter allows us to print much larger tissue scaffolds, at the scale of an entire human heart, with high quality.”

  • Building KDE Connect

    After I shared the link to the KDE Connect Development Telegram group almost 20 people joined within 24 hours. I certainly did not expect such a interest in KDE Connect. When I joined the project about a year ago the hardest part for me was setting up a proper development workflow, meaning configuring, building, installing and debugging the application and interacting with git and Phabricator. To ease your start in KDE Connect development I would like to give you the guide I wish I had back then.

    I will show you how to fetch the project, build, run and debug it using KDevelop. It’s an IDE by the KDE Community designed with KDE projects in mind. In theory you can use any IDE you like, if you figure out how to configure it properly.

  • KDE Connect – New stuff I

    In my first post about KDE Connect I told you about the album cover art on Android. Thanks to Matthijs it now also works when the cover art is a local file, for example when you are using VLC. It already worked when the cover art was a remote URL, for example with Spotify. The cover art is now also shown in the media control notification and added to the Android media session.

OSS and Openwashing Leftovers

  • Why retail marketers must get CX right the first time and how open source plays a key role

    One of the great things about technology is that it has raised all of our expectations. Once upon a time, people worried that controlling their television with a remote would make them lazy. Now, we don't even have to find the remote. We just talk to the TV — literally. We access hundreds of goods and services easily, without leaving the comfort of our chairs: we download games, order the supermarket shop, watch films and read books online. It really is a brave new world. But with new worlds come new challenges, and the challenge of the new, tech-driven, marketplace is to make your business stand out in a global crowd. Of all the businesses in all the world, why should your customers choose (and stick with) you? Lots of people will tell you that the key to gaining market share lies in improving the customer experience. And they'll be right. A combination of the need to impress and increased customer expectations have combined to make CX fundamental to gaining and retaining custom.

  • The Future of Great Customer Experience Relies on Open Source

    A majority of U.S. consumers feel that brands don't meet their expectations. The bar for customer experience has been set high -- and its on marketers to reach it. [...] In the early 2000s, enterprise IT was dominated by proprietary software companies. Now, with the rise of public cloud computing, more and more developers are adopting open source tools within their organizations due to lower overall costs and access to the latest innovations. The adoption is spreading from IT into other sectors of the business as well, notably marketing. In total, marketing and experience cloud vendors invested over $8 billion to acquire open source companies in 2018, according to PitchBook.

  • Tencent Offers Open-Source System for IoT Innovation

    Chinese internet giants are quickly cottoning onto the benefits of offering open-source technologies to global developers. Tencent is the latest to throw its hat into the ring. The company announced Wednesday that it is allowing developers to use an open-source operating system to create an internet-of-things (IoT) projects that will allow Tencent to improve the performance of its IoT solutions and strengthen its foothold in the sector. Called “TencentOS tiny,” the operating system is lighter, requires fewer resources, and uses less energy compared with other major systems, according to a Tencent release. The company also said it hopes TencentOS tiny will encourage developers to create IoT projects for smart cities, intelligent connected vehicles, and digital wearables — sectors that Tencent is aggressively targeting.

  • How spicy should a jalapeno be?

    Everyone has opinions and preferences, especially when it comes to food. To establish a criterion when answering "How spicy should a jalapeño be?." the Scoville Heat Scale was developed as a standard to measure spiciness. This scale allows people to communicate and share information about how spicy we like our peppers. Similarly, open source technology standards, such as USB, I2C, MQTT, and others, were developed to enable global compatibility. Furthermore, open source hardware platforms have enabled communities to “speak the same language” without reinventing the wheel. For example, Raspberry Pi makes it easy for people to use their hardware as a baseline and then add onto it. This has created a revolution in many industries by enabling individuals, startups, and large corporations to apply hardware and software to complex problems without having to design them from the ground up.

Linux 5.4 Adds Support For The FlySky FS-iA6B - A Receiver Popular With DIY Drones

The input driver updates for the Linux 5.4 kernel include the addition of an interesting, budget-friendly RC receiver that can be used for home-built drones and other use-cases while now the driver allows the receiver when paired with a supported RC controller to serve as a traditional Linux joystick input. The input updates were sent in earlier this week and among the changes are allowing drivers to support more precise timestamps for better velocity tracking, improvements to the BU21013 touchpad driver, and other changes as outlined in the pull request.
