    Xinhua's Japanese language edition tweeted this. Robot tractors, yes robot tractors. Click on the tweet to watch the video.

    Machine translation:

    China's self-driving tractor "Super Tractor No. 1" has started an autonomous driving test on farmland in Henan. During the test, the tractor planned the route automatically and avoided obstacles. “Super Tractor No. 1” was completed in October 2018 in Shenyang, Henan. It is considered the first electric tractor without a driver's seat in China.

    Huawei officially reveals Harmony OS, its first party operating system
    Mishaal Rahman

    In the city of Dongguan, China, Huawei finally took the wraps off its long-rumored, first-party operating system. The OS, called Harmony OS, has been in development for several years, but it’s recently taken on a role as a key player in Huawei’s contingency plan since the U.S. enacted a trade ban on the Chinese technology company. At the Huawei Developer Conference, Huawei finally shared the first details about its in-house OS, but the company wasn’t ready to show off Harmony on smartphones just yet. Tomorrow, the company will show off Harmony OS on the Honor Vision TV. For now, Android remains the go-to mobile OS for Huawei and Honor smartphones and tablets.

    Harmony OS is microkernel-based, like Google’s in-development Fuchsia OS. Huawei says that Fuchsia uses a “non-distributed design,” unlike Harmony OS. Huawei says this allows for flexible deployment on various devices, easing app development in all scenarios. To justify both of these claims, Huawei brings up that it is “hard to deliver a smooth experience across different devices with [a] huge amount of in Android and Linux core.” That’s because “multi-device interconnection [raises] requirements for security” and the “close-coupling between [the] app ecosystem and [the] hardware compromises [the] user experience and development efficiency.”

    The use of a microkernel also improves security, according to Huawei. Huawei says it is using “formal verification methods” to secure the TEE kernel. Huawei says this technique is mainly applied to security-critical fields like aerospace and chipsets, “significantly contributing to system reliability and robustness.” The microkernel can be “scaled on demand for wider system security.” In closing, Huawei boasts an EAL 5+ certification level for the new OS.

    Performance is theoretically better than Android and other Linux-based operating systems, according to slides shared by Huawei. Huawei says that Harmony OS uses a distributed virtual bus with a simplified protocol: Rather than 4 layers, there is only 1 layer in the protocol stack to “boost the payload efficiency.” The effects of this change to simplify interactions are “faster discovery and connections” of hardware like the display, cameras, speakers, etc. Unlike Android which uses the Linux kernel’s scheduling mechanism, Harmony OS uses a “deterministic latency engine” that provides “precise resource scheduling with real-time load analysis and forecasting and app characteristics matching.” The result is a 25.7% and 55.6% improvement in response latency and latency fluctuation respectively.

    Harmony “decouples” the OS from the hardware, so developers can develop once and deploy across hardware. Developers will be able to use Huawei’s ARK Compiler to compile code from multiple languages like C/C++, Java, and Kotlin for Harmony OS. Huawei will be providing an IDE to support app development across multiple device types, including televisions, car kits, smart speakers, smartphones, smartwatches, and more. This IDE “automatically adapts to varied screen layouts, controls, and interactions” and “supports drag-and-drop operations and preview-oriented visual programming”. Harmony OS will not allow for root access, which Huawei says is a security risk on Android and other Linux-based operating systems. Finally, Huawei will be open-sourcing Harmony OS in the future.

    Work on the new OS began 2 years ago with version 1.0 of the microkernel. In 2019, they accelerated work so the OS can work on more device types. Huawei says version 2.0 of its microkernel will be released next year while version 3.0 arrives in 2021. Huawei says they can switch to Harmony OS right now because the migration is not very difficult due to the nature of the microkernel; they boast they can switch from Android to Harmony in 1-2 days. However, the company is choosing to stick with Android on smartphones right now over consideration of its existing partners. Huawei says that its new OS represents an entirely new generation of operating systems as it enables AI capability in different scenarios from PCs, tablets, and other domains.

    We’ll learn more about Huawei’s new operating system this week at Huawei’s Developer Conference.

    Two things worth of noting from the reveal of Hongmeng OS (aka Harmony OS).
    • It is meant to be mobile OS, unlike the previous romure (or twisted quotation).
    • Android app (*.apk) can NOT be run sideloaded, it must be recompiled using the Ark compiler although the work is minimum, according to the following report.

    ... related is the tweet https://twitter.com/HenriKenhmann/status/1159769677586821120

    Comme ce qu’il avait été annoncé, le plan B préparé depuis quelques années pour « le cas où » devient aujourd’hui le plan A, Huawei présente son propre OS appelé HarmonyOS, un OS développé non pas comme un OS mobile mais un OS Internet of Things.
    Translated from French by
    As announced, plan B, which has been prepared for a few years for the "where" now becomes plan A, Huawei presents its own OS called HarmonyOS, an OS developed not as a mobile OS but as an OS Internet of Things.

    Harmony OS will likely be on IOT and smart objects that don't require an extensive app library, such as smart TVs and smartwatches. The question of transition to smartphones is another matter. Samsung's own first party OS, Tizen, can only be seen now in smart TVs and watches.

    There seems to be significant differences between Harmony OS and Android, like for instance, using a microkernel. Having its own OS project was smart to begin with, even without Trump or the trade war, as Google itself seems preparing to replace Android with its Fuschia OS. Ironically, among the first Fuschia OS devices that were tested on was Huawei devices.

    Sooner or later, Android will be replaced, even Google is preparing for this. It is just Trump hastened Huawei's pace. Decoupling Android earlier is more challenging, but maybe better than doing it later.

    Rather thanks to Trump he had hastened the pace for "MADE IN CHINA 2025".
