At one point in time, when you wanted to attach an external block storage device to a server, you mapped it as a Logical Unit (LU) across a Storage Area Network (SAN). In the early days, you would do this over the Fibre Channel (FC) protocol. More recently, iSCSI (SCSI over IP) has usurped FC in most data centers. more>>

The Cloud Native Computing Foundation (CNCF), which seeks to drive large-scale cloud computing with an emphasis on containers and microservices, has just added the Container Network Interface (CNI) project to its fold.

The project joins others hosted by the nonprofit foundation, including the Kuberrnetes container orchestration platform and CoreDNS DNS server. CNI had been a GitHub open source project. It features a specification and libraries to write plugins for configuring networking interfaces in Linux containers.

The foundation’s adoption of CNI is meant to increase its focus on network connectivity of containers and the removal of allocated sources when the container is deleted. “The idea [is] that CNI is a standard way of being able to use different networking technologies,” said Dan Kohn, the foundation’s executive director.

Lubuntu versus Xubuntu

Ubuntu has a number of different flavors, including Lubuntu and Xubuntu. Both of these Ubuntu flavors offer lightweight desktops, but which one is better?

A writer at Linux and Ubuntu recently weighed the pros and cons of Lubuntu and Xubuntu:

Over the years, Lubuntu and Xubuntu have been two popular flavors that have provided an alternative to a lot of folks who have preferred something other than vanilla Ubuntu with the Unity desktop. Lubuntu and Xubuntu have been the choice of Linux enthusiasts and users who would rather have a lean or lightweight Linux distro or one that will provide the best performance on an old desktop or laptop. But how do these two distros compare, which one would I recommend and why?

Premier Farnell, a distributor of Raspberry Pi, has created a kit that turns Raspberry Pi into a full-fledged desktop PC, running Linux.

What value does the Pi Desktop box bring to Raspberry Pi? Can’t you just use the Pi and use it as a desktop? Not really. First of all, there are no start, reboot or reset buttons on the device. Which means you can’t turn the PC off via a button.

“The built-in power switch makes the Pi Desktop easy to operate. An intelligent and safe power controller means that users do not have to remove the power adapter from the Pi board; they simply turn the power on or off like a desktop or laptop,” said Premier Farnell in a press release.

Is Steam bad for Linux gaming?

Valve has gotten a reputation for promoting Linux as a platform for gaming, and thus many people have a very positive view of the company. But is there a darker side to Valve?

One writer at Polygon is quite skeptical about Valve and its Steam gaming service, and he pulled no punches in a blistering article about the company.

Tim Colwill reports for Polygon:

This, then, is Good Guy Valve — a corporation which employs precision-engineered psychological tools to trick people into giving them money in exchange for goods they don't legally own and may never actually use while profiting from a whole lot of unpaid labor and speculative work ... but isn't “evil.”

Will Linux protect you from ransomware attacks?

Ransomware attacks are all the rage these days among hackers, and many people are worried about becoming victims. Are Linux users secure against such attacks?

This topic came up recently in a thread on the Linux subreddit, and the folks there had some interesting thoughts to share about Linux and ransomware attacks.

Rytuklis started the thread with this post:

I am sure you guys heard the news about that huge hacker attack that locks peoples personal fines and demands ransom. Is Linux secure enough to protect against such attacks?

I thought I was safe on Windows in Lithuania where such attacks are very rare but saw this hack also hit Lithuania pretty hard too, so it makes me contemplate Linux again.

It's been a long time in the works, but a memory management feature intended to give machine learning or other GPU-powered applications a major performance boost is close to making it into one of the next revisions of the kernel.

Heterogenous memory management (HMM) allows a device’s driver to mirror the address space for a process under its own memory management. As Red Hat developer Jérôme Glisse explains, this makes it easier for hardware devices like GPUs to directly access the memory of a process without the extra overhead of copying anything. It also doesn't violate the memory protection features afforded by modern OSes.

Tectonic, CoreOS's Linux platform built to run containers, was revamped this week to version 1.6.2. Underneath that minor point revision label lie some significant changes.

According to an official CoreOS blog post, this version of Tectonic rolls in the latest version of Kubernetes (1.6.2) to create a CoreOS/Kubernetes combo that's easier to install in a variety of environments and has better separation of workloads, more robust auditing and logging, and boasts a major change a key underlying Kubernetes technology.

A more elastic etcd

That key technology is etcd, the distributed data store used by CoreOS generally and by Kubernetes in particular. With a new experimental feature, CoreOS can manage etcd with CoreOS Operators.

Fans of Windows Subsystem for Linux (WSL) love that it provides a native Linux experience, command line and all, to Windows users. But not all have been fans of the choice of Linux distribution—Canonical's Ubuntu Linux—and thus have launched projects to swap out Ubuntu.

ALWSL is one such project, and the Python-based WSL Distribution Switcher, which provides automated access to no fewer than 10 Linux distribution userlands, is a more sophisticated approach.

Hewlett Packard Enterprises' HP-UX OS has been around for more than 30 years, and users may be looking to move on from the Unix-based OS.

Now HPE is offering a way out of the ancient OS using containers, which are small buckets running instances of applications. The containers will be offered with the Linux OS.

HPE will provide containers to transition from conventional mainframe-style OSes to new hardware like x86-based Xeon servers. In this case, HPE is trying to get users to transition from Itanium chips.

Linux: How to protect your privacy

Privacy is an issue on many people’s minds these days, including those that run Linux on their computers. Linux has long had a strong reputation as a secure operating system, but there are still things that you can do to help protect your privacy while running Linux.

The DuckDuckGo blog has a list of privacy tips for Linux users:

It’s easy to have a false sense of security, thinking that other operating systems might be more targeted than Linux, but there are plenty of risks and vulnerabilities for all types of Linux devices. Keep your guard up regardless of your OS.

  1. Ensure you use a password to protect your user account.

Last year Microsoft added an unusual new feature to Windows 10: Linux support. The Windows Subsystem for Linux (WSL) — sometimes called Bash on Windows — is “Microsoft’s implementation of a Linux-compatible infrastructure that runs atop and within the Windows kernel,” senior program manager Rich Turner tells CIO.com. That means running Linux binaries without leaving Windows.

“Bash on Windows offers a toolset for developers, IT administrators and other tech professionals that want or need to run Linux command-line tools alongside their Windows tools and applications,” Turner explains. Developed with the help of Canonical (and a large community of Linux users), it’s not there to turn Linux into Windows, or Windows into Linux. It’s just that some Linux tools are so ubiquitous for development and deployment that it’s useful to be able to use them without spinning up a virtual machine (VM). That’s one of the reasons Macs are so popular with developers: MacOS is based on BSD, which is Unix, so it can run Linux tools like Bash. And now, so can Windows 10.

Will Google dump Android for Fuchsia?

Google’s new Fuchsia operating system doesn’t use the Linux kernel. Instead the company has created its own microkernel called Magenta. Google has given the world its first look at Fuchsia, and many people are wondering if the company will eventually replace Android with Fuchsia.

Ron Amadeo reports for Ars Technica:

With any new project at Google, it's hard to know what the scale of the project will be. Is this a "20 percent" project that will be forgotten about in a year or something more important? Luckily, we have a direct statement from a Fuchsia developer on the matter. In the public Fuchsia IRC channel, Fuchsia developer Travis Geiselbrecht told the chat room the OS "isn't a toy thing, it's not a 20% project, it's not a dumping ground of a dead thing that we don't care about anymore."

Is Linux kernel design outdated?

Linux has made great strides over the years, advancing far beyond where it was when it started. But one redditor recently wondered if Linux was suffering from outdated kernel design. He asked his question in the Linux subreddit and got some interesting answers.

Ronis_BR started the thread with these comments:

I have been a Linux user since 2004. I know a lot about how to use the system, but I do not understand too much about what is under the hood of the kernel. Actually, my knowledge stops in how to compile my own kernel.

However, I would like to ask to computer scientists here how outdated is Linux kernel with respect to its design? I mean, it was started in 1992 and some characteristics did not change. On the other hand, I guess the state of the art of OS kernel design (if this exists...) should have advanced a lot.

GUIs are great—we wouldn’t want to live without them. But if you’re a Mac or Linux user and you want to get the most out of your operating system (and your keystrokes), you owe it to yourself to get acquainted with the Unix command line. Point-and-click is wonderful whenever you need to do something once or twice. But if you need to repeat that task many times, the command line is your savior.

The command line is a window into the full, awesome power of your computer. If you long to break free of the constraints of the GUI or think that programming or administering remote machines is in your future, then learning the Unix command line is definitely for you.

Linux containers have taken infrastructure computing by storm. What started with Linux VServer, OpenVZ, cgroups, and LXC has gained momentum with the rise of Docker. You can think of a container as a lightweight VM that virtualizes the Linux kernel instead of hardware. This up-leveling of the virtualization brings in better performance, high density, and portability across clouds, whether public, private, or hybrid.

Containers are like VMs in many respects but are typically used for running individual daemons or services rather than multiple services or monolithic applications. Containers make creating and upgrading applications easy, but also introduce complexity via the increased number of instances and interdependencies to manage. This complexity gave rise to container orchestration systems like Mesos, Docker Swarm, and Kubernetes.

OpenSuse’s great leap backward

OpenSuse has been around for quite a long time, and it’s one of the better known Linux distributions. But recently there’s been quite a controversy brewing over OpenSuse’s change in version numbers. A writer at LWN.net delved into the controversy and had some interesting thoughts to share.

While this change is controversial, the OpenSuse board hopes that it will lead to more rational versioning in the long term — but the world has a way of interfering with such plans.
