More Windows Server vs. Linux Benchmark Tests With Spectre/Meltdown Mitigations

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

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.

  • [Podcast] PodCTL #31 – Reviewing Kubernetes 1.10

    Like clockwork, a new release of Kubernetes comes out every quarter. And with the arrival of Spring comes Kubernetes 1.10. Stability, Security, Networking and Storage are front of center of the new release. This week we dig into the 1.10 release and highlight some of the features that we believe will have the biggest impact on customers being able to deploy more applications on Kubernetes (and ultimately OpenShift).

  • 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?"

  • Product Review: GitStorage

    By profession, I'm a software developer. Aside from a preferred editor, what matters most to a developer is the use of a Source Code Manager (SCM). So, when a new product comes along featuring my favorite SCM, Git, I had no choice but to spend some time using it.

  • 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.

Carnegie Mellon University's 'Open-Source' 3-D Bioprinter

  • 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.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
