  • Linux-friendly embedded computer runs on Apollo Lake power

    Axiomtek has released a rugged, Ubuntu-ready “eBOX627-312-FL” embedded PC with a dual-core Celeron N3350, 2x GbE, 6x USB, and 4x serial ports plus mini-PCIe, HDMI, SATA, and “Flexible I/O.”

  • EPIC board boasts 4x GbE ports and PCIe x4

    Aaeon is rolling out a new EPIC form-factor “EPIC-KBS9” SBC with 6th or 7th Gen Core S-series chips, 4x GbE ports, up to 32GB DDR3, and mini-PCIe and PCIe x4 expansion.

    Aaeon’s EPIC-KBS9 follows two other EPIC-KBS SBCs to support Intel’s 6th “Skylake” or 7th “Kaby Lake” generation S-Series processors: the EPIC-KBS7, which emphasized real-world ports, and last month’s EPIC-KBS8, which is a bit more feature rich but with fewer coastline ports. Unlike these earlier models, the KBS9 offers 4x GbE ports, up to 32GB DDR4-2133, and a full-size PCIe x4 slot, which supports NVMe storage.

  • L1 Terminal Fault - The Latest Speculative Execution Side Channel Attack

    Details are still light but a new vulnerability is coming out called the L1 Terminal Fault. It's been described as a "train-wreck" and is another big deal in the security space as the latest speculative side-channel attack vector.

    The CVEs are CVE-2018-3615, CVE-2018-3620, and CVE-2018-3646 but as of writing they have not been made public yet. I just noticed the code hitting the mainline Linux kernel to this "L1TF - L1 Terminal Fault" vulnerability.

  • Ubuntu updates for L1 Terminal Fault vulnerabilities

    Today Intel announced a new side channel vulnerability known as L1 Terminal Fault. Raoul Strackx, Jo Van Bulck, Marina Minkin, Ofir Weisse, Daniel Genkin, Baris Kasikci, Frank Piessens, Mark Silberstein, Thomas F. Wenisch, Yuval Yarom, and researchers from Intel discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that’s executing on the CPU core. Processors from other vendors are not known to be affected by L1TF.

Hardware

If you haven’t kept up with the world of e-ink displays, here’s some good news: they are pretty cheap now. For as little as $15 you can get a small e-ink display that has good enough performance and contrast to actually do something useful. There’s only one problem: figuring out how to drive them in your project.

Tired of seeing nothing but wiring diagrams and sample code when it came to actually putting these e-ink modules to use, [Jouko Strömmer] decided to try his hand at creating a turn-key application for these gorgeous little displays. The result is PaperTTY, a Python program that allows the user to open up a fully functional Linux virtual terminal on an e-ink display.

  • Threadripper 2900 Series Temperature Monitoring Sent In For Linux 4.19 Then Backported

    As expected, the CPU temperature monitoring support within the "k10temp" hwmon driver has seen the patches sent in today to be updated for the AMD Threadripper 2900 series CPU support. These patches are going into the Linux 4.19 kernel merge window but slated to be back-ported to the currently supported stable kernel series.

  • AMD Threadripper 2950X Offers Great Linux Performance At $900 USD

    The embargo has expired now for talking about Threadripper 2 performance figures... First up are our initial Threadripper 2950X Linux benchmarks. In this article are the most interesting metrics for this 16-core / 32-thread processor while in the just-published AMD Threadripper 2990WX Linux Benchmarks are a lot more figures complemented by the 2950X and other CPUs plus power consumption numbers, etc. This article is most useful if specifically focused on the performance of the Threadripper 2950X that comes in at $899 USD.

  • AMD Threadripper 2990WX Cooling Performance - Testing Five Heatsinks & Two Water Coolers

    The 32-core / 64-thread AMD Threadripper 2990WX carries a 250 Watt TDP rating, thus the cooling performance is quite important especially if you don't want to hit any thermal throttling with this $1799 USD processor. Fortunately, the 2990WX doesn't require water cooling but actually can work quite well with high-end air heatsinks too. For adding some perspective on the cooling requirements of the Threadripper 2990WX, here are benchmarks of five heatsinks and two all-in-one water cooling systems.

  • AMD Threadripper 2990WX Linux Benchmarks: The 32-Core / 64-Thread Beast

    Whether you are compiling a lot of code, rendering models with Blender, or running various scientific workloads with OpenMP or MPI, the AMD Threadripper 2990WX is capable of delivering immersive Linux performance with its 32-cores and 64 total threads. While coming in at $1800 USD, the AMD Threadripper 2990WX can deliver better performance than the more expensive Intel Core i9 7980XE. Beyond being mesmerized about the performance today with this high-end desktop/workstation processor with the many thread-happy Linux workloads we encounter daily, this 32-core Zen+ processor has us even more eager to see AMD's next-generation Zen2-based EPYC CPUs next year.

Build Your Own Linux Single Board Computer

GNU
Linux
Hardware

We are fortunate enough to have a huge choice of single-board computers before us, not just those with a bare-metal microcontroller, but also those capable of running fully-fledged general purpose operating systems such as GNU/Linux. The Raspberry Pi is probably the best known of this latter crop of boards, and it has spawned a host of competitors with similarly fruity names. With an entire cornucopia to choose from, it takes a bit more than evoking a berry to catch our attention. The form factors are becoming established and the usual SoCs are pretty well covered already, show us something we haven’t seen before!

[Marcel Thürmer] may have managed that feat, with his Blueberry Pi. On the face of it this is just Yet Another SBC With A Fruity Pi Name, but what caught our attention is that unlike all the others, this is one you can build yourself if you want. It’s entirely open-source, but it differs from other boards that release their files to the world in that it manages to keep construction within the realm of what is possible on the bench rather than the pick-and-place. He’s done this by choosing an Alwinner V3, an SoC originally produced for the action camera market that is available in a readily-solderable TQFP package. It’s a choice that has allowed him to pull off another constructor-friendly feat: the board is only two layers, so it won’t break the bank to have it made.

  • Samsung Galaxy Watch, Running Tizen, is Launched

    Today, as expected, Samsung have launched a new smartwatch, the Samsung Galaxy Watch, yes, the name change is real (previously it has been known as the Gear S4). At the Samsung Unpacked event, we were given the Note 9 and the Galaxy Watch. The big headline for us is the watch will not be running Wear OS, as speculated once upon a time, but the Galaxy Watch will be running Tizen 4.0.

    We will have two models to choose from: 46mm available in silver and a 42mm black and rose gold versions. Samsung have realised that “one size does not fit all” and some might find a smaller watch face appealing.

  • Building a better thermostat with Home Assistant

    Next, I needed to look at software to use my hardware acquisitions as a thermostat. While all my devices were Z-Wave, and OpenZWave provides both C++ and Python interfaces I could use to access and control my devices, it was a bit too low-level for my taste.

    Instead, I decided to use the Home Assistant project, for a few reasons. First, I know a bunch of people who use it, hack on it, or both. Second, while all my current devices are Z-Wave, Home Assistant will let me branch out to use other kinds of devices if I want. Home Assistant supports a ton of different devices and services—you can look at the component list to see them all. For Z-Wave support, it leverages OpenZWave and provides a higher level interface that is a bit easier to deal with. Home Assistant is written in Python 3, which is very convenient for me since I do most of my programming in Python. It also has an active community that has been responsive and helpful.

    I installed Home Assistant on one of my servers and proceeded to configure its interface with my devices. There is a lot of detailed information available on setting up Home Assistant—you can refer to the official documentation for a starting point. For specific Z-Wave instructions, see the Z-Wave section in the Home Assistant docs.

    After setting up Home Assistant, I had a single web interface and API for controlling my new power switches and displaying data from the MultiSensor. But, I still didn't have a thermostat—just a pretty interface (that I could use remotely) for manually turning the AC on or off.

  • IP65 protected panel PCs feature Apollo Lake or Core-U chips

    Ibase announced three open-frame panel PCs with Linux support. The 15-inch, 1024 x 768 OFP-151-PC and 21-inch, 1920 x 1080 OFP-2100-PC run on the Pentium N4200 while the 21-inch OFP-2101-PC offers a choice of 7th Gen Core-U CPUs.

    Ibase, which last year launched an SE-102-N signage player, has now returned with a pair of fanless, open-frame touch-panel PCs that similarly run Linux 4.x or Windows 10 on an Intel Apollo Lake SoC. The 15-inch, 1024 x 768 OFP-151-PC and 21-inch, 1920 x 1080 OFP-2100-PC ship with a quad-core, 1.1/2.5GHz Pentium N4200 with 6W TDP.

ZX Spectrum Vega+ blows a FUSE: It runs open-source emulator

Filed under

Gadgets

The ZX Spectrum Vega+ is running open-source Spectrum emulator software FUSE, The Register has confirmed while carrying out a hands-on review of the handheld console.

As regular readers know, the Vega+ is the flagship product of Retro Computers Ltd, the company which took £513,000 in crowdfunded cash from members of the public to produce handheld ZX Spectrum-themed gaming consoles. It failed to deliver any for two years and then belatedly emitted what appear to be several dozen of the devices last week.

With public interest at an all-time high in what the company has actually produced during the ongoing scandal, El Reg acquired one from an RCL customer for review purposes.

No instructions were supplied with the console. In time-honoured retro gaming fashion, The Register’s crack review team resorted to button-mashing to figure out what did what.

  • NASA project allows students to build their own mini Mars rover

    Students, hobbyists and enthusiasts can now build a scaled-down version of the Mars rover using plans and instructions from NASA's Jet Propulsion Laboratory's (JPL) Open Source Rover Project.

    The laboratory has built a mini-rover --"ROV-E" -- to engage the public, and the model has been brought into classrooms and museums to demonstrate rover mobility firsthand.

  • Basic Engine: $10 open-source gadget designed to be the best game machine of the 1980s

    The Basic Engine is a tiny but intentionally limited computer platform designed to be like a late-1980s game console or home computer, but with some useful modern benefits. In effect, it's like Pico-8, but hardware instead of a set of abstract and arbitrary design limitations on software.

  • Beginning BLE Experiments And Making Everything Better

    Successfully connecting things without physical wires has a profound effect on the maker brain. Machines talking to each other without any cables is as amazing today as it was a decade ago. When Bluetooth came out, it was a breakthrough since it offered a wireless way to connect cellphones to a PC. But Bluetooth is a complicated, high-bandwidth power hog, and it didn’t make sense for battery-powered devices with less demanding throughput requirements to pay the energy price. Enter Bluetooth LE (BLE), with power requirements modest enough to enable a multitude of applications including low power sensor nodes and beacons.

  • Now you can build your own mini Mars rover

    The idea for the Open Source Rover (OSR) was inspired by the extremely positive reception to ROV-E, a smaller, working version of Curiosity that served as an educational tool for high school and college students. After students and teachers repeatedly inquired as to how they could build their own robotic rover, JPL engineers got to work.

  • NASA project lets you build a mini Curiosity rover using a Raspberry Pi

    The company revealed that its Jet Propulsion Laboratory (JPL) is hosting the initiative, called the Open Source Rover Project, which will allow students, hobbyists, and enthusiasts being to learn the skills required to build their own rover.

    Using plans and instructions from JPL, the Open Source Rover is a scaled down version of Curiosity, a rover which successfully landed on Mars back in 2012. It even has the same 6-wheel steering and Rocker-Bogie suspension, NASA said.

    JPL has published this design under an open source license on GitHub where anybody can download baseline instructions and test plans for building their own open source rover using a Raspberry Pi.

    "We wanted to give back to the community and lower the barrier of entry by giving hands on experience to the next generation of scientists, engineers, and programmers," said project sponsor for the Open Source Rover, Tom Soderstrom.

Kernel: Qualcomm/Atheros "Ath10k", FUSE and Code of Conduct

  • Linux's Qualcomm Ath10k Driver Getting WoWLAN, WCN3990 Support
    The Qualcomm/Atheros "Ath10k" Linux driver coming up in the Linux 4.20~5.0 kernel merge window is picking up two prominent features. First up, the Ath10k driver is finally having WoWLAN support -- Wake on Wireless LAN. WoWLAN has been supported by the kernel for years and more recently is getting picked up by Linux networking user-space configuration utilities. Ath10k is becoming the latest Linux wireless driver supporting WoWLAN (WIPHY_WOWLAN_NET_DETECT) for automatically waking up the system when within range of an a known SSID.
  • FUSE File-Systems Pick Up Another Performance Boost With Symlink Caching
    FUSE file-systems in user-space are set to be running faster with the upcoming Linux 4.20~5.0 kernel thanks to several performance optimizations. The FUSE kernel code for this next Linux kernel cycle already has a hash table optimization and separately is copy file range support for efficient file copy operations. Staged today into the FUSE tree for the next cycle was yet another performance-boosting patch.
  • Another Change Proposed For Linux's Code of Conduct
    With the Linux 4.19-rc8 kernel release overnight, one change not to be found in this latest Linux 4.19 release candidate are any alterations to the new Code of Conduct. The latest proposal forbids discussing off-topic matters while protecting any sentient being in the universe. While some immediate changes to the Linux kernel Code of Conduct have been talked about by upstream kernel developers, for 4.19-rc8 there are no changes yet. We'll presumably see some basic changes land this week ahead of Linux 4.19.0 expected next Sunday as not to have an unenforceable or flawed CoC found in a released kernel version.

Plasma 5.14 – Phasers on stun

Linux is much like the stock market. Moments of happiness broken by crises. Or is the other way around? Never mind. Today shall hopefully be a day of joy, for I am about to test Plasma 5.14, the latest version of this neat desktop environment. Recently, I’ve had a nice streak of good energy with Linux, mostly thanks to my experience with Slimbook Pro2, which I configured with Kubuntu Beaver. Let’s see if we can keep the momentum. Now, before we begin, there are more good news woven into this announcement. As you can imagine, you do need some kind of demonstrator to test the new desktop. Usually, it’s KDE neon, which offers a clean, lean, mean KDE-focused testing environment. You can boot into the live session, try the desktop, and if you like it, you can even install it. Indeed, neon is an integral part of my eight-boot setup on the Lenovo G50 machine. But what makes things really interesting is that neon has also switched to the latest Ubuntu LTS base. It now comes aligned to the 18.04 family, adorned with this brand new Plasma. Proceed. Read more
