  • 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.

Intel Core i9 9900K vs. AMD Ryzen 7 2700X Linux Gaming Benchmarks

Complementing the just-published Intel Core i9 9900K Linux benchmarks with the launch-day embargo lift are the Linux gaming benchmarks... This article is looking at the Linux performance between the Core i9 9900K and AMD's Ryzen 7 2700X in a variety of native Linux games as well as comparing the performance-per-Watt. So if you are a Linux gamer and deciding between these sub-$500 processors, this article is for you. If you didn't yet read the main article that features a 15-way CPU comparison on Ubuntu 18.10 with the Linux 4.19 kernel, here is a recap of this new Coffeelake refresh CPU. The Core i9 9900K is an eight-core / sixteen-thread processor with 3.6GHz base frequency and 5.0GHz turbo frequency. This 14nm CPU has a 16MB L3 cache, dual channel DDR4-2666 support, and a 95 Watt TDP. There is also the onboard UHD Graphics 630, but if you're a gamer, that isn't going to cut it. The Core i9 9900K is launching at $499 USD. Read more

Intel Core i9 9900K Linux Benchmarks - 15-Way Intel/AMD Comparison On Ubuntu 18.10

Intel sent over the Core i9 9900K as their first 9th Gen Coffeelake-S CPU hitting store shelves today. With the embargo on that now expired, let's have a look at how well this eight-core / sixteen-thread processor performs under Linux. The Core i9 9900K is Intel's new answer for competing with the likes of the AMD Ryzen 7 2700X, but does come at a higher price point of $499 USD. While the Core i9 9900K is a Coffeelake refresh, rather than being six cores / twelve threads, they are matching AMD's precedent set by the Ryzen 7 processors in having eight cores / sixteen threads. This 14nm 8C / 16T processor has a base clock frequency of 3.6GHz with a turbo frequency at 5.0GHz, a 16MB L3 cache and supports dual-channel DDR4-2666 memory. Read more

Google: Desktop, Server and Kernel

  • Chrome OS Linux support to gain folder sharing, Google Drive, more
    Chrome OS has been shaping up to be the all-in-one system, combining the best of Google’s ecosystem, including Android apps, with the power of Linux apps. The latter is still in beta phase with improvements and new features in every update. Today we take a look at some of the features coming soon to Chrome OS Linux apps. Chrome OS first gained its Linux app support, also known as Crostini, with version 69. While it’s certainly not flawless, the support has been groundbreaking, enabling everything from full photo editors to Android Studio on Chrome OS. With upcoming versions of Chrome OS, Google is working to smoothen the rough edges of Crostini to make it easier to use.
  • Google Cloud CTO Brian Stevens on using open source for competitive advantage in the public cloud
    As all three continue to vie for the affections of CIOs, how they market their respective public cloud propositions to enterprise IT buyers has subtly shifted over time. For evidence of this, one only has to look at how little fuss the big three now make about rolling out price cuts for their services compared to several years ago, when one provider announcing a price drop would not only make headlines, but prompt its competitors to publicly follow suit too. This in itself is indicative of the fact enterprises expect more from providers than just access to cheap commodity IT services these days, and that ongoing cost reductions are simply an accepted part of using cloud, Google Cloud CTO Brian Stevens, tells Computer Weekly.
  • KUnit: A new unit testing framework for Linux Kernel
    On Tuesday, Google engineer Brendan Higgins announced an experimental set of 31 patches by introducing KUnit as a new Linux kernel unit testing framework to help preserve and improve the quality of the kernel’s code. KUnit is a lightweight unit testing and mocking framework designed for the Linux kernel. Unit tests necessarily have finer granularity, they are able to test all code paths easily solving the classic problem of difficulty in exercising error handling code.
