Changing Up Your Linux Distro | Best of ECT News

This story was originally published on Feb. 27, 2018, and is brought to you today as part of our Best of ECT News series.

It’s common for Linux users to hop between distributions and survey the field, and I recently reached a point where I had to seriously rethink the one I was using most of the time.

Between hardware compatibility issues with my old standby and some discouraging missteps with other go-to choices, I felt the time had come to reassess my pool of preferred distributions and repopulate it from scratch.

As my journey progressed, I realized that as often as I’ve discussed the field of Linux-based systems, I had not addressed how to pick one out. To give you an idea of how to approach distribution selection, I wanted to volunteer my recent search as one template. This is certainly not the only or best way to go about it — everyone has their own criteria and priorities — but my intention is to provide some reference points for mapping out your own way.

My Former Linux Flames

Before getting into how I ended up where I did, I’ll provide a snapshot of the distributions I came from. Formerly, my distribution of choice was Arch Linux. In use cases where hardware compatibility is solid and unshakable stability is not paramount, it still is.

After troubleshooting in my early Linux days repeatedly took me to the Arch Wiki, the appeal of embracing the distribution that produced such extensive documentation grew until it eventually won me over.

The distribution I previously reserved as a fallback in case Arch got too dicey was Ubuntu. Besides the fact that Ubuntu also has thorough documentation and a helpful community, it has the backing of a major player, its parent company Canonical. These factors made Ubuntu my refuge when dependability became essential.

So how did these two end up getting displaced from their lofty positions? Since some of the reevaluations I made about Ubuntu influenced my view of Arch, I’ll start there.

As I noted in an earlier piece, Ubuntu recently and egregiously
dropped the ball in terms of kernel maintenance. Late last year, Ubuntu included an experimental module in its version of the kernel, despite warnings from the upstream Linux kernel project (the source of the stock kernel that all distributions inherit and respectively customize) that it wasn’t ready. While there’s nothing wrong with pushing the envelope — it’s a good way to stand out in Linux’s crowded pack — this is an area where a conservative approach is wiser.

The unfinished Intel SPI driver in the Ubuntu 17.10 kernel went on to
damage the boot firmware — the extremely sensitive code directing your computer how to turn on — on machines by several manufacturers.

Mistakes do happen, even among Linux titans, but while I can’t prove this definitively, I suspect that Canonical’s termination of Ubuntu’s Unity desktop project and the ensuing organizational shakeup threw off its work somewhat.

Although this error was specific to Ubuntu, it led me to acknowledge that Arch, with its cutting-edge kernel, runs a higher risk of a similar stumble, since there is less time to test changes passed down from the upstream Linux kernel project. For me personally, when the stars align, there’s no other Linux experience like Arch, but that happens less often than I would like.

Consider This

I considered a number of worthy distributions before reaching my destination. By virtue of its exalted station in the Linux world,
Debian is worth a look for any Linux user. Debian outmatches most distributions in stability, and it is exceptionally lightweight, so it has a lot going for it.

Ironically, its solidity is why I eliminated it: In trying not to shake things up, Debian’s default kernel is too basic to support the features I need. You can swap in a more advanced kernel, but you have to switch to the Testing or Unstable tracks and reduce system stability comparably to Arch’s, at which point I’d rather use Arch.

In general, with the Debian experience you either take it or leave it — and for me, there were enough unappealing elements to choose the latter.

Another distribution I weighed was
openSuse, especially since it is regarded for security. Another draw is that it has two equally supported tracks, “Leap” for a smooth and dependable experience, and “Tumbleweed” for the thrill of the latest upgrades.

However, my research revealed that Leap suffers from Debian’s rigidity, and Tumbleweed from Arch’s volatility (perhaps more so).

Finally, I entertained a notable newcomer,
Solus. The distribution has climbed the rankings on
Distrowatch.com, and it showcases considerable polish, such as its impressive Budgie flagship desktop.

Unfortunately, as a distribution a small team developed from scratch (i.e., not based on any other), its selection of packages is limited. Additionally, while the Budgie desktop has made great strides, it is in the middle of a daunting transition. It simultaneously has been changing its underlying libraries from GTK to Qt and its display server from the ubiquitous X to the upstart Wayland. I am eager to try Solus once this transformation is complete, but I’ll leave them alone during the messy interim.

Top of the Heap

The distribution that emerged victorious in this contest was
Manjaro. While based on Arch, Manjaro holds onto its packages a little longer for further testing before release, adding stability. It also offers users what is probably the widest selection of kernel versions to run of any distribution I’ve seen. Best of all for those of us who revel in Arch, Manjaro takes the menial grunt work out of configuring Arch without compromising its power.

For a stability-minded auxiliary, I chose
Linux Mint. It’s possibly more stable than Debian, but still manages a slightly more adventurous update track. Moreover, the Mint update manager is a particularly impressive feat of engineering — it both streamlines the update process and adds granularity to the tracks users can follow. By dividing updates into five classes of potential system impact, users can choose the balance they want to strike.

My jaunt through the Linux ecosystem took me a long way and yet not very far: I ended up with two distributions that are built on my previous two.

Even so, I learned a lot in the process, and I found systems that are that much closer to my ideals. Does that mean you should use them too? Maybe, but just because they’re best for me — for now — doesn’t mean they are for you, too.

By relating my experience, my intention is to supply an example of the kinds of priorities you might want to consider, and how to weigh them. If you haven’t sampled many distributions, I hope you’ll now feel confident enough to give some of them a try. Consider this a little push!

‘Open Source Creators: Red Hat Got $34 Billion and You Got $0. Here’s Why.’

Wednesday October 31, 2018 @11:21AM

from the quick-primer dept.

Donald Fischer, who served as a product manager for Red Hat Enterprise Linux during its creation and early years of growth, writes:

Red Hat saw, earlier than most, that the ascendance of open source made the need to pay for code go away, but the need for support and maintenance grew larger than ever. Thus Red Hat was never in the business of selling software, rather it was in the business of addressing the practical challenges that have always come along for the ride with software. […] As an open source developer, you created that software. You can keep your package secure, legally documented, and maintained; who could possibly do it better? So why does Red Hat make the fat profits, and not you? Unfortunately, doing business with large companies requires a lot of bureaucratic toil. That’s doubly true for organizations that require security, legal, and operational standards for every product they bring in the door. Working with these organizations requires a sales and marketing team, a customer support organization, a finance back-office, and lots of other “business stuff” in addition to technology. Red Hat has had that stuff, but you haven’t.

And just like you don’t have time to sell to large companies, they don’t have time to buy from you alongside a thousand other open source creators, one at a time. Sure, big companies know how to install and use your software. (And good news! They already do.) But they can’t afford to put each of 1100 npm packages through a procurement process that costs $20k per iteration. Red Hat solved this problem for one corner of open source by collecting 2,000+ open source projects together, adding assurances on top, and selling it as one subscription product. That worked for them, to the tune of billions. But did you get paid for your contributions?

You will be successful in your work.

Book Review: Absolute FreeBSD (3rd Edition)

Book Review: Absolute FreeBSD 3rd ed

FreeBSD is a free and open source operating system for many different kinds of computers. FreeBSD’s based upon BSD, the version of UNIX developed at the University of California, Berkeley. FreeBSD is an alternative to Linux or Windows-based system. You can run almost all apps written in Perl, Python, PHP and other programming languages. FreeBSD heavily used by Netflix, EMC, IBM, Juniper, NetApp, Apple, Sony, and others. Absolute FreeBSD (3rd ed) book aims to be the complete guide to FreeBSD. Let us see why Michael W. Lucas’ FreeBSD system administration books so favorite among Unix lovers.

Book Review: Absolute FreeBSD (3rd Edition)

The book starts with an introduction to FreeBSD operating system and its history and strengths. The book divided into twenty-four chapters:

  1. Getting More Help – You may find yourself needing more help about FreeBSD even after reading the book. The author talks about using man pages and resources on the Intenet to find more help match your requirements.
  2. Before You Install – Before you start configuring FreeBSD box, you need to install FreeBSD. The author provides tips on avoiding common mistakes while installing FreeBSD.
  3. Installation Walk-Through – This chapter provides a quick overview of installing FreeBSD with different filesystems and options.
  4. Start Me Up! The Boot Process – The understanding of the FreeBSD boot process is an essential task for a sysadmin. Quite useful to solve and troubleshoot server issues.
  5. Read This Before You Break Something Else! (Backup and Recovery) – The author talks about how to back up the FreeBSD system so that one can recover from human mistakes or system failures.
  6. Kernel Games – The author explains how to configure the FreeBSD kernel to meet your requirements using the sysctl command, device drivers, custom kernel configs and more.
  7. The Network – In this chapter, Michael talks about the basis of TCP/IP protocol.
  8. Configuring Networking – The seventh chapter covered the theoretical part of TCP/IP. It is time to get hand dirty and learn actual commands that one can use to configure FreeBSD networking, routing, DNS, NIC teaming, VLAN and more.
  9. Securing Your System – Securing the Internet-connected system is an essential task for the sysadmin. One can secure users, groups, files, FreeBSD system security level, and more.
  10. Disks, Partitioning, and GEOM – Another import task is to configure and manage hard drives and partitions on your system. The author talks about partitioning schemes, disk alignment, and commands to manage disks under FreeBSD operating system.
  11. The Unix File System – Unix File System (UFS) has been part of FreeBSD and Unix-like system for decades. ZFS is a cool FS but the much older system (read as “legacy” systems) and newer cloud-based system hosted by AWS/Google cloud by default use UFS. Learning UFS and its management commands are another crucial tasks for sysadmins.
  12. ZFS – UFS is a 40-year-old and reliable file system for FreeBSD. However, ZFS is a newer and recommend filesystem to store a large amount of data, virtual machines, backups and more. One can learn about ZFS datasets, pools, virtual devices, and management commands for ZFS. (see also Book Review: FreeBSD Mastery – ZFS)
  13. Foreign Filesystems – UFS and ZFS are the first class citizen of FreeBSD. Nevertheless, as a sysadmin one might need to mount different disks or configure file system for different client machines. The author talks about DVD/CD, ISOs, burning DVDs, temfs, configuring NFS/CIFS to create classic Unix file server and more. (see also Book Review: FreeBSD Mastery – Storage Essentials)
  14. Exploring /etc – The author talks about the many configuration files in FreeBSD and how they work.
  15. Making Your System Useful – Applications are the main reason to use any server and the author demos how to install, configure, remove, manage various applications on FreeBSD box using pkg command.
  16. Customizing Software with Ports – The author talked about pkg command in the previous chapter. For most users, pre-built packages work out of the box, but in some cases, one might need to configure packages as per needs. FreeBSD ports provide additional tunning and building options for applications, and the author explains how to use FreeBSD ports system in details.
  17. Advanced Software Management – The author talks about various concepts and commands for running software on FreeBSD systems such as SMP based system, rc scripts used at boot or shutdown times, shared libraries and more.
  18. Upgrading FreeBSD – Want to upgrade FreeBSD system? Read this chapter to upgrade FreeBSD either using binary or source method.
  19. Advanced Security Features – Over the years FreeBSD added the more exciting security features. The author discusses some of the important ones such as stateful packet filtering, public key encryption, OpenSSL, preparing system for intrusions, monitoring system, packages and more.
  20. Small System Services – Want to turn FreeBSD into a small business server for LAN/WAN users? The author talks about popular services such as DHCP, email, time (ntpd), ssh (openssh), print server and more.
  21. System Performance and Monitoring – Monitoring and running FreeBSD server is an essential task for the seasoned sysadmin. One can learn about the various command to find out the bottleneck that slowed down the system. The author talks about FreeBSD’s performance testing and troubleshooting tools that one might need to use to solve problems in production environments.
  22. Jails – One must run all internet facing services in an isolated environment to maintain system security and integrity when you have multiple users or services. FreeBSD comes with Jails, and the author talks about setting up Jails to improve FreeBSD system security.
  23. The Fringe of FreeBSD – The author covers some interesting topics such as running server/desktop without disks (diskless booting), and cloud-friendly features such as libxo. The libxo allows a FreeBSD application to generate text, XML, JSON, and HTML output using a standard set of function calls.
  24. System (and Sysadmin) Crashes and Panics – Software and hardware crash. Sometimes one might find a ghost in the machine. How does one deal with rare occasions when a FreeBSD system fails? Fear not, the author shows how to debug problems, and create a useful problem report.

Absolute FreeBSD is a fantastic book on FreeBSD. Clear. Concise. Informative for new FreeBSD users and sysadmins. The author gives out best practices to learn FreeBSD operating system management and exciting tips to improve your skills. Lastly, I think this book is a must-have book for all people interested in learning FreeBSD system managment.

Fedora 29 Officially Released, Red Hat Enterprise Linux 7.6 Launched, New Version of Linux Lite, Google AI Tracking Humpback Whale Songs, and Resin.io Announces openBalena and a Name Change

News briefs for October 31, 2018.

The Fedora Project Manager announced the official release of Fedora 29 yesterday. This release is the first to include the Fedora Modularity feature across
all variants. Other changes include “GNOME 3.30 on the desktop, ZRAM for our ARM images, and a Vagrant image
for Fedora Scientific”. You can download it from here.

Red Hat Enterprise Linux 7.6 launched yesterday with improved security. eWeek reports that the new release features “TPM 2.0 support for security authentication, as well as integrating the open source
nftables firewall technology effort”. eWeek quotes principal project manager Steve Almy: “The TPM 2.0 integration in 7.6 provides an additional
level of security by tying the hands-off decryption to server hardware in addition to the network bound disk
encryption (NBDE) capability, which operates across the hybrid cloud footprint from on-premise servers to
public cloud deployments.” Version 7.6 is the second major milestone release of 2018.

Linux Lite 4.2 Final is now available. Linux Lite creator Jerry Bezencon says the release is “a ‘refinement’ and not a ‘major upgrade’.
There are some new wallpapers thanks to @whateverthing and some minor tweaks here and there.” One change with
this version is the addition of
Redshift, which “adjusts the color temperature according to the position of the sun”.

Google and a group of cetologists have been using AI to listen to years of undersea recordings with the hope of
creating “a machine learning model that can spot humpback whale calls”. According to TechCrunch, the project is part of Google’s AI for Social Good
initiative.

Resin.io, a container-based server platform for Linux device management, has “changed its name to balena and released an
open source version of its IoT fleet management platform for Linux devices called openBalena”, Linux
Gizmos reports
. Founder and CEO of the company says the name change is due to “to trademark issues, to
cannabis references, and to people mishearing it as ‘raisin'”. balenaOS is “an open
source spinoff of the container-based device software that works with balenaCloud”, and the new openBalena “is an
open version of the balenaCloud server software. Customers can now choose between letting balena manage their
fleet of devices or building their own openBalena based server platform that manages fleets of devices running
balenaOS”.

Seeing Further – 5 Things to Know About SUSE HPC

Share with friends and colleagues on social media

High performance computing (HPC) – the use of supercomputers and parallel processing techniques for solving complex computational problems – has traditionally been limited to the world of large research institutions, academia, governments and massive enterprises. But now, advanced analytics applications using artificial intelligence (AI), machine learning (ML), deep learning and cognitive computing are increasingly being used in the intelligence community, engineering and cognitive industries.

The need to analyze massive amounts of data and transaction-intensive workloads are driving the use of HPC into the business arena and making these tools mainstream for a variety of industries. Commercial users are getting into high performance applications for fraud detection, personalized medicine, manufacturing, smart cities, autonomous vehicles and many other areas. In order to effectively and efficiently run these workloads, SUSE has built a comprehensive and cohesive OS platform. In this blog, I will illustrate five things you should know about our SUSE solutions for AI over HPC.

Stronger partnerships

The first thing to know is how vital SUSE partnerships are to our HPC business. While the SLE HPC product can be obtained through direct Sales, it historically has been made available via our IHV and ISV partners. But obtaining the OS and associated HPC tools is only half of the story. Our key partnerships provide opportunities to innovate and contribute to open source development in AI/ML/DL and leading-edge advanced analytics applications.

Hewlett Packard Enterprises’ HPC software includes open source, HPE-developed and commercial HPC software that’s validated, integrated and performance-optimized for their systems. SUSE is the preferred HPE partner for Linux, HPC, OpenStack and Cloud Foundry solutions. And SUSE technology is embedded in every HPE ProLiant Server to power the intelligent provisioning feature. We have several joint papers that describe how SUSE and HPE together deliver HPC power to enterprises.

ARM System on a Chip (SoC) partners are driving new HPC adoptions in the modern data center. And SUSE is helping transform the 64-bit ARM platform to an enterprise computing platform by being the first commercial Linux distributor to fully support ARM servers. In fact, SUSE provides ARM HPC functionality as part of SLE HPC. The increased server density on the latest 64-bit ARM processors really helps to optimize the overall infrastructure costs – making Arm-based supercomputers more affordable. ARM SoC partners include Marvell (formerly Cavium), AMD, HPE, Cray, MACOM, Huawei HiSilicon, Mellanox, XILINX, Gigabyte, Qualcomm and more.

Cray builds their own Cray Linux Environment (CLE) – an adaptive operating system, purpose-built for HPC and designed for performance, reliability and compatibility – it also happens to be built on SUSE Linux Enterprise. Cray supercomputers continue to have a majority share of the Top500 sites around the world. And Cray is a key player in HPC, producing both Intel-based and ARM-powered supercomputers.

Lenovo’s strategy is to provide open access to clusters on their new highly efficient processors. SUSE and Lenovo jointly defined the scope of the Lenovo HPC stack using SUSE HPC componentry. In turn, Lenovo created the LiCO (Lenovo Intelligent Computing Orchestration) adaptation – a premier AI/HPC package tailored to power AI/ML/DL workloads.

Those are just a few highlights of key partnerships for SUSE and HPC. Others include NVIDIA, Microsoft Azure, Fujitsu, Intel, Univa, Dell Technologies, Altair, ANSYS, MathWorks, Supermicro and Bright Computing. Another aspect of partnering in open source is continuing to be a major contributor in communities that guide parallel computing – including OpenHPC (where SUSE is a founding member), OpenMP and many more involved in shaping HPC tools.

More differentiators

The second thing to know is the clear and concise set of HPC platform differentiators. This list encompasses what’s available in the SUSE OS as well as for HPC storage and HPC in the cloud:

  • SUSE Enterprise Storage is Ceph-based and software-defined, providing backup and archival storage for HPC environments that is very easy to manage
  • SLE HPC is enabled for Microsoft Azure and AWS Cloud
  • SLE HPC and associated HPC packages are fully supported for Aarch64 (Arm) and x86-64 architectures
  • Supported HPC packages, such as slurm for cluster workload management, are included with SLE HPC subscriptions. Also in the same HPC Module are Ganglia for cluster monitoring, OpenMPI, OpenBLAS, FFTW, HDF, Munge, MVAPICH and more.
  • SLE HPC is priced very competitively, and uses a simple, one price per cluster node model
  • SLE HPC provides ESPOS (Extended Service Pack Overlay Support) for longer service life for each service pack
  • SUSE Enterprise Linux is used in about half of the top 100 HPC systems around the world
  • SUSE Package Hub includes SUSE-curated and community-supported packages for HPC.

AI/ML focus

The third thing to know is our increased focus on the AI/ML market space and how we are providing the most efficient and effective HPC platform for these new workloads in a parallel computing environment. Technologies like cognitive computing, the Internet of Things and smart cities are powered by high performance computing and fueled by advanced data analytics. Businesses around the world today are recognizing that a Linux-based HPC infrastructure is vital to supporting the analytics applications of tomorrow. And we are finding that HPC is not just for scientific research any longer, and being adopted across banking, healthcare, retail, utilities and manufacturing.

In healthcare, an HPC platform underlies applications such as AI for precision medicine, diagnoses and treatment plans, cancer research, genomics and drug research. In the automotive world, we see HPC being used in aerodynamic designs, engine performance and timing, fuel consumption, safety systems and AI driverless operations. In manufacturing, HPC is vital for computational fluid dynamics, heat dissipation system design, AI advanced robotics, automated systems and other high-performance designs. And in energy, we find HPC as the basis for air flow designs in renewable energy, wind turbines and heating/cooling efficiencies.

SUSE Linux Enterprise HPC is integral to a highly scalable parallel computing infrastructure for supporting AI/ML and analytics applications being used across industries.

Restructured product

The fourth thing to know is how we’ve restructured our SLE HPC product with our goal of making HPC easier to implement and adapt. With SUSE’s concerted effort to make HPC easier to adopt, implement and maintain we have recently made the following changes:

  • Invoked a simple, one price per cluster node model with significantly reduced list prices that can be used by IHVs, ISVs and direct Sales.
  • SLE HPC is available for x86 and Arm HPC clusters
  • SLE HPC has a new “level 3 support” SKU specifically for partners
  • There are multiple service life options including Extended Service Pack Overlap Support and Long-Term Service Pack Support
  • There are revised terms and conditions for smaller cluster sizes and increased clarity on defining compute nodes
  • More frequent updates on demand for popular HPC packages, supported by SUSE

Growing market share

The fifth and final thing to know is that SUSE continues to grow its market share in the supercomputing arena, as evident by the market share in the latest Top500 report. The latest analysis of the Top500 supercomputer sites report shows that half of the top 30 run SUSE, expanding to 40% of the top 100. One of the most compelling statistics from the report is when we look at the vendor share of paid OS, which represents 116 supercomputers in the top 500 list. Here we see that over half of the paid Linux OS in the top 500 are running SUSE.

From the same segment, we also calculated the paid OS “performance share”, which is based on the total number of cores across 116 supercomputers. Here again we see that over half of the paid-for Linux OS in the top 500 are SUSE.

I will be providing more specifics on all of the areas I talked about in this blog post over the next several months, but hopefully I’ve given you a decent “first look”.

With our open and highly collaborative approach through our strong partner ecosystem, we can help deliver the required knowledge, skills and capabilities that will shape the adoption of HPC and AI technologies today and power the new analytics applications of tomorrow.

Steam Play for Linux now lets you play over 2,600 Windows games


Steam Play for Linux now lets you play over 2,600 Windows games

ProtonDB has said users can play over 2,600 Windows games on Linux since the launch of the new Steam Play for Linux in August.

Valve launched Steam Play with Proton, making it easier for gamers to play Window games on Linux that had not yet been ported to the operating system, including games such as The Witcher 3, Dark Souls 3, and Dishonored.

Not all games may run perfectly on Linux, but the number of available games is growing daily.

This, however, is often the case with Windows 10, as it cannot play older games as well as the previous versions of Windows could – even under Compatibility Mode.

Since August, the database of games compatible with Proton has increased to over 2,600, which is more than half of the 5,000 Linux-native games that you can get through the Steam store.

System76’s new ‘open-source computer’ will be available for preorder November 1

The hardware vendor specializing in Linux systems has set a date for its latest venture. Their new Thelio desktop systems will be available for preorder soon.

For those of you unaware of System76 [Official Site], they’ve been selling Linux-powered laptops, mini computers and servers for a few years now and have even created their own Ubuntu derivative named Pop!_OS. Last month they started teasing their newest project, Thelio, which aims to be an open hardware desktop system.

Details on what the hardware will entail specifically are still a little light, and we’ll likely only know for sure when the system goes up for preorder, but there’s a few things that we can say for sure. In reply to a tweet sent by Liam asking whether or not they’d have a custom motherboard, the CEO clarified that “we’re pulling proprietary functionality off the mainboard and onto a custom, open source (hardware and firmware) daughter board.”

This open firmware will be GPLv3-licensed and you can already check out the master repository for the Thelio on GitHub. Personally, I can’t really make much heads or tails of the various bits of code and teaser blueprints and hardware schematics that System76 and its CEO have been posting in the last few weeks but I can say that I am excited to see a hardware vendor work on their own custom solutions for the Linux desktop.

I suppose we’ll just have to see what the prices are like when preorders go live November 1. Systems are expected to be shipped in December of this year. You may also want to check out the animated saga that System76 have created around Thelio.
