Containers bring a skinny new world of virtualization to Linux

Filed under

Linux
Server

Once upon a time, if you ran a data center, you used virtual machine (VM) management programs (i.e., hypervisors) There was no other practical choice. This dates all the way back to the good old IBM 360 mainframe days with CP-67/CMS in 1967. Today, our data centers and clouds run more advanced hypervisors. Amazon Web Services (AWS), for example, is made up of nearly half-a-million Linux servers running the Xen hypervisor, while Microsoft's Azure cloud relies upon its Hyper-V hypervisor.

OpenPOWER Foundation to reveal innovations in Big Data

Filed under
Server

The OpenPOWER Foundation is going to reveal new innovations around Big Data technology in the next Open Innovation Summit on April 23, 2014. The OpenPOWER Foundation is a collaboration of technology companies on Power Architecture products initiated by IBM. It is building an ecosystem around IBM POWER hardware and software and making it available for open development for the first time. Canonical has also added support for PowerSystems in the recently released Ubuntu Linux 14.04.

Security

The Heartbleed fallout continues, but enterprise customers can draw some comfort from the fact that the companies that keep them in software are clearly as concerned as they are. For example, Oracle Corp. has announced mostly good, some bad and a bit of ugly news when it comes to security holes in its products.

Ubuntu 12.04 LTS vs. 14.04 LTS Cloud Benchmarks

Graphics/Benchmarks
Server
Ubuntu

These regressions are a bit frightening but we are still in the process of conducting further tests -- both bare metal and in the public clouds -- to try to figure out more closely what's going on. However, for most users I wouldn't hold off on upgrading to Ubuntu 14.04 LTS since it will ultimately be needed for the longest support within enterprise environments, for desktop users there are plenty of new features, the hardware enablement is much better on 14.04 LTS, the open-source graphics stack is much better, and there's many other non-performance advantages in using Ubuntu 14.04 LTS.

Opteron X Berlin runs Fedora Linux

  • Opteron X Berlin runs Fedora Linux

    Berlin is the first 28nm-based CPU and APU product from AMD for the Opteron server market and this APU is supposed to replace Opteron 3300 series based on 4 to 8 Piledriver cores. Berlin has four Steamroller cores, but its APU supports HSA and it theoretically should be able to run some parallel computing applications much faster.

GNU/Linux on Power8 Servers

  • IBM Gearing Up for New Power8 Servers

    IBM reported its first quarter fiscal 2014 results late Wednesday, once again showing weakness in its server hardware business. Big Blue however has a plan to change its hardware business fortunes.

  • IBM Throws Power8 Gauntlet At The Feet Of X86

    IBM is particularly keen on promoting Linux on Power, and Schroeter said that there are now over 800 independent software vendors whose wares are certified to run on the Power-Linux combo. Many of the hyperscale and extreme scale customers that IBM would love to sell Power-based machines to have their own variants of Linux as well as their own applications, so they can relatively easily port their code to Power should it make sense for performance reasons. This is, in fact, the bet that Big Blue is making. It may not be as bold as the bet the company made to create the System/360 mainframe 50 years ago, but the company is not walking away and remains committed to using Power machinery behind its Watson service and continuing to design processors for both Power and System z platforms into the future.

Nvidia Is Preparing An Unexpected Surprise For Linux Users In 2020

Each year Nvidia hosts the GPU Technology Conference, a global gathering of AI developers, data scientists, graphic artists, and pretty much anyone in the technology industry working with GPUs in their chosen fields. The event packs in keynotes with roadmaps and reveals, face-time with Nvidia engineers, and hundreds of sessions to participate in. GTC 2020, though, looks to include a special surprise for Linux users and open source enthusiasts. Supporting Nouveau eh? That’s the open source Linux driver used to drive Nvidia graphics cards (Nvidia also supplies a proprietary driver for Linux), and Nvidia’s historical lack of contributions is what led Linus Torvalds to famously flip Nvidia the bird and utter words I can’t print here. (I can link to them though. . .) The community of developers working on the Nouveau driver have experienced several roadblocks throughout the years. Paramount among them is the inability to achieve normal GPU clock speeds due to Nvidia’s locked down firmware on many models of graphics cards. This leads to undesirable performance and a multitude of potential video display issues across many Linux distributions. Read more

Pekwm: A lightweight Linux desktop

Let's say you want a lightweight desktop environment, with just enough to get graphics on the screen, move some windows around, and not much else. You find traditional desktops get in your way, with their notifications and taskbars and system trays. You want to live your life primarily from a terminal, but you also want the luxury of launching graphical applications. If that sounds like you, then Pekwm may be what you've been looking for all along. Pekwm is, presumably, inspired by the likes of Window Maker and Fluxbox. It provides an application menu, window decoration, and not a whole lot more. It's ideal for minimalists—users who want to conserve resources and users who prefer to work from a terminal. Read more

What motivates people to contribute to open source?

Knowing what motivates people is a smart way to recruit contributors to an open source project—and to keep them contributing once they've joined. For his book How Open Source Ate Software, Red Hat's Gordon Haff did a lot of research on the topic of motivation, and he shared some of it in his Lightning Talk at All Things Open 2019, "Why do we contribute to open source?" Watch Gordon's Lightning Talk to learn about the three main types of motivation—extrinsic, intrinsic, and internalized extrinsic—what they are, and how they relate to open source communities.
