Compact module runs Ubuntu on AMD’s Ryzen Embedded V1000 SoC

Filed under
Ubuntu

Seco announced an Ubuntu-ready “COMe-B75-CT6” COM Express Type 6 Compact module featuring AMD’s new Ryzen Embedded V1000, and offering support for four simultaneous 4K displays and an optional industrial temperature range.

Earlier this week, we covered Congatec’s COM Express Type 6 Basic (125 x 95mm) Conga-TR4 module, which features the 14nm Ryzen Embedded V1000, AMD’s new successor to the R-Series “Merlin Falcon.” Seco, meanwhile, announced the COMe-B75-CT6 — the first Type 6 Compact module based on the V1000 — sporting the smaller 95 x 95mm Compact form factor.

Security: “Medjacking”, Exploding e-Cigarettes, and Linux FUD

  • “Medjacked”: Could Hackers Take Control of Pacemakers and Defibrillators—or Their Data?

    Are high-tech medical devices vulnerable to hacks? Hackers have targeted them for years, according to a new article in the Journal of the American College of Cardiology. But Dr. Dhanunjaya Lakkireddy, senior author of the paper, says hackers have harmed no one so far.

  • Exploding e-Cigarettes Are a Growing Danger to Public Health

    Whatever their physiological effects, the most immediate threat of these nicotine-delivery devices comes from a battery problem called thermal runaway

    [...]

    Exploding cigarettes sound like a party joke, but today’s version isn’t funny at all. In fact, they are a growing danger to public health. Aside from mobile phones, no other electrical device is so commonly carried close to the body. And, like cellphones, e-cigarettes pack substantial battery power. So far, most of the safety concerns regarding this device have centered on the physiological effects of nicotine and of the other heated, aerosolized constituents of the vapor that carries nicotine into the lungs. That focus now needs to be widened to include the threat of thermal runaway in the batteries, especially the lithium-ion variety.

  • Uh, oh! Linux confuses Bleeping Computer again

    The tech website Bleeping Computer, which carries news about security and malware, has once again demonstrated that when it comes to Linux, its understanding of security is somewhat lacking.

    What makes the current case surprising is the fact that the so-called security issue which the website chose to write about had already been ripped to pieces by senior tech writer Stephen Vaughan-Nicholls four days earlier.

    Called Chaos, the vulnerability was touted by a firm known as GoSecure as one that would allow a backdoor into Linux servers through SSH.

  • Are Mac and Linux users safe from ransomware?

    Ransomware is currently not much of a problem for Linux systems. A pest discovered by security researchers is a Linux variant of the Windows malware ‘KillDisk’. However, this malware has been noted as being very specific; attacking high profile financial institutions and also critical infrastructure in Ukraine. Another problem here is that the decryption key that is generated by the program to unlock the data is not stored anywhere, which means that any encrypted data cannot be unlocked, whether the ransom is paid or not. Data can still sometimes be recovered by experts like Ontrack, however timescales, difficulty and success rates depend on the exact situation and strain of ransomware.

Benchmarking An ARM 96-Core Cavium ThunderX System

Graphics/Benchmarks

A Phoronix reader granted us remote access to a FOXCONN C2U4N_MB system featuring two Cavium ThunderX 48-core SoCs. For those curious about the potential of a modern 96-core ARM platform, here are some basic benchmark results.

The last time I had access to a 96-core ARM configuration for testing was six years ago when helping out on a 96-core Ubuntu ARM solar-powered computer.. Back then it was built out of PandaBoard ES development boards with their 1.0GHz dual-core Cortex-A9 processors while since then ARM technology has advanced a great deal.

Oracle Adds Support for Linux Kernel 4.15 to Its Latest VirtualBox Release

Filed under
Linux

VirtualBox 5.2.8 is now available to download, finally bringing support for the latest Linux 4.15 kernel series for Linux-based guest operating systems you might want to run on your virtual machines. Also, this means that various of VirtualBox's modules can now be compiled against Linux kernel 4.15.

Also, VirtualBox 5.2.8 finally addresses that annoying black screen issue that occurred when 3D was enabled in some Linux guests, and adds support for suppressing setuid and setgid in shared folders. For Windows guests, the update fixes an incorrect function error that occurred when using shared folders with certain apps.

Hands-On with Ubuntu's New "Minimal Installation" Feature in Ubuntu 18.04 LTS

Filed under
Ubuntu

The feature is called "Minimal Installation" and it's an option that will be available for those who need it on the "Preparing to install Ubuntu" screen of Ubuntu's installer, right after you select the keyboard layout. As you can imagine, the option is disabled by default.

Enabling it will install Ubuntu with a minimal desktop environment consisting of a web browser and the standard utilities, at least that's what option's description tells us. So we took it for a test drive and installed the current development version of Ubuntu 18.04 LTS with the Minimal Installation option in a VM.

  • Looking Back: What Was Happening Ten Years Ago?

    A decade passes so quickly. And yet, ten years for open source is half its life. How have things changed in those ten years? So much has happened in this fast-moving and exciting world, it's hard to remember. But we're in luck. The continuing availability of Linux Journal's past issues and website means we have a kind of time capsule that shows us how things were, and how we saw them.

    Ten years ago, I was writing a regular column for Linux Journal, much like this one. Looking through the 80 or so posts from that time reveals a world very different from the one we inhabit today. The biggest change from then to now can be summed up in a word: Microsoft. A decade back, Microsoft towered over the world of computing like no other company. More important, it (rightly) saw open source as a threat and took continuing, wide-ranging action to weaken it in every way it could.

    Its general strategy was to spread FUD (fear, uncertainty and doubt). At every turn, it sought to question the capability and viability of open source. It even tried to convince the world that we no longer needed to talk about free software and open source—anyone remember "mixed source"?

    Alongside general mud-flinging, Microsoft's weapon of choice to undermine and thwart open source was a claim of massive patent infringement across the entire ecosystem. The company asserted that the Linux kernel violated 42 of its patents; free software graphical interfaces another 65; the OpenOffice.org suite of programs, 45; and assorted other free software 83 more. The strategy was two-fold: first to squeeze licensing fees from companies that were using open source, and second, perhaps even more important, to paint open source as little more than a pale imitation of Microsoft's original and brilliant ideas.

  • Chrome OS may allow for running Linux apps via Containers

    While the average Chromebook user tends to stick with Chrome OS, Chromebooks are really just lightweight Linux machines capable of a lot more. For years, crafty Chromebook owners have been using Crouton (Chromium OS Universal Chroot Environment) to run Ubuntu, Debian, and Kali Linux systems within Chrome OS. When set up properly with an extension called Xiwi, you can use a keyboard shortcut to switch between Chrome OS and a standard Linux desktop environment. It’s a hack, but it looks a future version of Chrome OS will add native support for Linux applications via containers.
