Evaluate Linux server distros for your data center

Filed under

Linux
Server

Most data centers include Linux, but there are many Linux server distros to choose from. Deciding which one is the right fit for your data center can be confusing, but there are three main options: Ubuntu Server, Red Hat Enterprise Linux and CoreOS.

Linux is flexible, reliable, agile and secure, which makes it a strong contender for enterprises and SMBs. If you want your Linux OS to cover a wide range of use cases, you cannot go wrong with Ubuntu Server 18.04. This Ubuntu version is a long-term support release, and it's capable of serving large scale-out needs, as well as some more specific workloads, such as database servers, web servers, lightweight directory access protocol servers and OpenStack.

Ubuntu Server supports the ZFS volume management/file system, which is ideal for servers and containers because it includes all the tools you need for containers and clustering, as well as snap universal package support. It is also certified as a guest on AWS, Microsoft Azure, Joyent, IBM, Google Cloud Platform and Rackspace.

When it comes to Linux server distros, Ubuntu Server has many customization options and few system requirements. Ubuntu Server is terminal-only; you can install a GUI desktop environment, but that can consume precious system resources.

  • Sony using open source emulator for PlayStation Classic plug-and-play

    ReARMed is a popular, modernized branch of the original PCSX emulator, which was actively developed from 2000 to 2003 for Linux, Mac, and Windows. A new branch called PCSX Reloaded picked up that development later in the decade, adding new features and fixing bugs and eventually leading to the ReARMed fork. The emulator supports network play and a "save rewind" feature that lets you easily reverse recent gameplay, two features that seem to be missing from the PlayStation Classic.

  • Playstation Classic is using the open-source PCSX emulator in order to play its games

    A lot of console gamers were hyped when Sony announced the Playstation Classic. However, it appears that Sony has not developed its own emulator and instead it is using the open source PCSX emulator that most PC gamers have been using all these years.

    What ultimately this means is that the overall emulation may not be that “authentic” as some gamers may have expected. We’ve seen this happening in SNES classic and to be honest I was expecting Sony to put some more effort to it.

  • PlayStation Classic Using Open Source Emulator, 50Hz Versions of Games in Europe

    The PlayStation Classic has always seemed like a bit of a hasty attempt by Sony to try and cash in on the popularity of the NES Classic Mini and SNES Classic Mini’s success. Which is fine, of course—the PlayStation brand has a history and a legacy that deserves to be celebrated, too.

    But the hastiness of the effort seems to have compromised it. The list of games on the hardware seems to be, well, not the best, while there are basic baffling decisions like the decision to not have the controllers be the DualShock controllers, instead reverting to the no-analog original controllers.

Solus Linux is Under New Management

Ikey made his marks on Linux over the years by contributing to a variety of projects (not limited to the Brisk Menu and Linux Steam Integration). He worked on Linux Mint for while before starting his own Ubuntu based distro. After running into development limitations, Ikey created his own Linux distro from scratch. He did this all while working for Intel on their Linux distro. Last June, Ikey took the huge step of leaving his job at Intel to work full time on Solus.

Besides being involved with Solus full-time, Ikey joined the Late Night Linux podcast. In August of 17, the show covered a news story about the Krita project running into problems with the tax man. In that episode, Ikey revealed that he intended to make sure that Solus would not suffer a similar situation. In fact, he wanted to make sure that if something happened to him, the project would survive. Kinda prophetic

  • Librem 5 Development Kits: we are getting there!

    A few weeks ago we published an update about the forthcoming of our Librem 5 development kits when we ran into some issues which caused delays. Today we’re bringing you another update on the hardware fabrication process, as well as some pictures and a video. At the same time as the last update got posted, I was on my way to California, where we are fabricating our development kit and base boards (we are bringing everything to life there, and shipping from that same facility).

    [...]

    The MIPI DSI display interface is of extremely important, and we can not order the final batch of PCBs before we know that the display (and touch controller) work perfectly. By doing the verification we also indeed discovered some problems, minor things that did not behave as expected and which we are now able to fix. Some other issues are simply mechanical issues that are hard to evaluate just from all the datasheets. And then other things happen, like parts not conforming to standards (like the M.2 WiFi/BT card, of which we got samples just a few days after doing the prototype order). For example, the M.2 card has some pretty thick components on the bottom layer and thus can not lay flush on the PCB (which had been an assumption we had when we designed the board), so we need to change the connector for the final boards.

  • Purism Still Working On Librem 5 Developer Kits, Delayed To December

    The Librem 5 GNU/Linux smartphone was originally slated to launch in January 2019 and its developer kits were supposed to ship this past summer. Now it's looking like the Librem 5 Developer Kits will hopefully arrive in December.

    This summer the developer boards were delayed to at least August and in the months since have relayed various delays. Last month they said the kits would ship "very shortly following shipping delays while now that is turning into December.

Security Updates and FUD

  • Security updates for Friday
  • Linux CryptoMiners Are Now Using Rootkits to Stay Hidden [Ed: This impacts already-cracked machines; unlike Windows, where rootkits come though official channels like CD-ROM (Sony)]

    As the popularity of cryptocurrency rises, so does the amount of cryptominer Tojans that are being created and distributed to unsuspecting victims. One problem for cryptominers, though, is that the offending process is easily detectable due to their heavy CPU utilization.

    To make it harder to spot a cryptominer process that is utilizing all of the CPU, a new variant has been discovered for Linux that attempts to hide its presence by utilizing a rootkit.

    According to a new report by TrendMicro, this new cryptominer+rootkit combo will still cause performance issues due to the high CPU utilization, but administrators will not be able to detect what process is causing it.

    "We recently encountered a cryptocurrency-mining malware (detected by Trend Micro as Coinminer.Linux.KORKERDS.AB) affecting Linux systems," stated a report by TrendMicro. "It is notable for being bundled with a rootkit component (Rootkit.Linux.KORKERDS.AA) that hides the malicious process’ presence from monitoring tools. This makes it difficult to detect, as infected systems will only indicate performance issues. The malware is also capable of updating and upgrading itself and its configuration file."

  • Linux cryptocurrency miners are installing rootkits to hide themselves [Ed: By hiring Catalin Cimpanu CBS ZDNet basically imported the same misleading headlines and style as the sensationalist Bleeping Computer (above, where he came from). Because all CBS judges "success" by is clicks and ad impressions.]

Apple's long-awaited refresh of the Mac Mini includes a component called the "T2 Security Chip" which Apple touts as having "a Secure Enclave coprocessor, which provides the foundation for APFS encrypted storage, secure boot, and Touch ID on Mac," as well as integrating "the system management controller, image signal processor, audio controller, and SSD controller," which were separate components in previous Mac systems. Because of the extent to which T2 is involved with the boot sequence of this new hardware, Apple controls what operating systems can be loaded onto their hardware.

Import your files from closed or obsolete applications

One of the biggest risks with using proprietary applications is losing access to your digital content if the software disappears or ends support for old file formats. Moving your content to an open format is the best way to protect yourself from being locked out due to vendor lock-in and for that, the Document Liberation Project (DLP) has your back.

According to the DLP's homepage, "The Document Liberation Project was created to empower individuals, organizations, and governments to recover their data from proprietary formats and provide a mechanism to transition that data into open and standardized file formats, returning effective control over the content from computer companies to the actual authors."

Essential System Tools: journalctl – query and display messages from the journal

Linux
Software

Systemd (stylized as systemd) is a suite of software that provides fundamental building blocks for Linux. It’s a Linux-specific system and service manager, offering an init system used to bootstrap the user space and to manage system processes after booting. The software provides a standard process for controlling what programs run when a Linux system boots up. Systemd, was created by Red Hat’s Lennart Poettering and Kay Sievers. It provides more than running core programs. It also starts a journal of system activity, the network stack, a cron-style job scheduler, user logins, and many other jobs.

systemd has courted a lot of controversy with some legitimate concerns about its design details (for example, the decision to use binary logs), and debate about whether it extends its reach too far. Nevertheless, this system and service manager has been adopted by many popular Linux distributions such as Fedora, Ubuntu, Debian, openSUSE, and Arch. Why? Essentially, because it offers a fast boot-up, parallelizing the boot process, as well as being designed with security in mind with most daemons running at minimal privileges. It also unifies system objects, and offers a simple configuration file language.

Why you should care about RISC-V

Filed under
Hardware

If you haven’t heard about the RISC-V (pronounced “risk five”) processor, it’s an open-source (open-hardware, open-design) processor core created by the University of Berkeley. It exists in 32-bit, 64-bit, and 128-bit variants, although only 32- and 64-bit designs exist in practice. The news is full of stories about major hardware manufacturers (Western Digital, NVidia) looking at or choosing RISC-V cores for their product.

But why should you care? You can’t just go to the local electronics boutique and buy a RISC-V laptop or blade server. RISC-V commodity hardware is either scarce or expensive. It’s all still early in its lifespan and development, not yet ready for enterprise tasks. Yet it’s still something that the average professional should be aware of, for a number of reasons.

By now everyone has heard about the Meltdown and Spectre issues, and related “bugs” users have been finding in Intel and AMD processors. This blog is not about how hard CPU design is – it’s hard. Even harder than you realize. The fear created by these bugs was not that there was a problem in the design, but that users of these chips had no insight into how these “black boxes” worked, no way to review code that was outside their control, and no way to audit these processors for other security issues. We’re at the mercy of the manufacturer to assure us there are no more bugs left (ha!).

Must-Have Tools for Writers on the Linux Platform

Linux

I’ve been a writer for more than 20 years. I’ve written thousands of articles and how-tos on various technical topics and have penned more than 40 works of fiction. So, the written word is not only important to me, it’s familiar to the point of being second nature. And through those two decades (and counting) I’ve done nearly all my work on the Linux platform. I must confess, during those early years it wasn’t always easy. Formats didn’t always mesh with what an editor required and, in some cases, the open source platform simply didn’t have the necessary tools required to get the job done.

Kdenlive 18.08.3 is out with updated build scripts as well as some compilation fixes. All work is focused on the refactoring branch so nothing major in this release. On the other hand in the Windows front some major breakthroughs were made like the fix of the play/pause lag as well as the ability to build Kdenlive directly from Windows. The next milestone is to kill the running process on exit making Kdenlive almost as stable as the Linux version.

In other news, we are organizing a bug squash day on the first days of December. If you are interested in participating this is a great opportunity since we have prepared a list of low hanging bugs to fix. See you!

  • IBM's $34bn acquisition of Red Hat: Our take

    We take the long view on the tech giant's colossal acquisition of open-source software company Red Hat.

    Given its love of technology and innovation, the Leaders League news team was most intrigued by IBM’s announcement in late October that it was purchasing open-source software company Red Hat. Having had some time to think about it, we’ve written a recap that also points to the future.

    IBM’s move signifies a strong commitment (in the shape of a $34bn cash purchase) to keeping up at the cloud game, and there’s little doubt that this is where the future lies: even in the face of the GDPR, lawyers and industry bods alike are sanguine about the Internet of Things and the deep, broad possibilities of cloud storage. According to research and advisory firm Gartner, the hybrid cloud market will be worth $240bn by 2019.

  • Making sense of IBM-Red Hat in the multi-cloud era

    Big Blue wants Red Hat because it is “the world’s leading provider of open-source cloud solutions, and the emerging leader in the platforms for hybrid cloud and multi-cloud,” IBM CEO Ginni Rometty said in a conference call Monday.

    Red Hat Enterprise Linux is known for its CloudForms hybrid cloud management tool, based on the ManageIQ open source project.

    “This is about resetting the cloud landscape, and we will be the undisputed No. 1 leader in hybrid cloud,” Rometty said.
