LiteOS
Huawei LiteOS is a discontinued lightweight real-time operating system (RTOS) developed by Huawei. It is a POSIX compliant operating system for Internet of things (IoT) devices, and free and open-source software, released under a BSD 3-clause license. Microcontrollers of different architectures such as ARM (M0/3/4/7, A7/17/53, ARM9/11), x86, and RISC-V are supported by the project. Huawei's LiteOS is part of their '1+8+N' Internet of things system, and has been featured in several open source software development kits and industry offerings. Smartwatches by Huawei and its former Honor brand run LiteOS. LiteOS variants of kernels has since been incorporated into the IoT-oriented HarmonyOS with open source OpenHarmony. History On 20 May 2015, at the Huawei Network Conference, Huawei proposed the '1+2+1' Internet of Things solution and release the IoT operating system named Huawei LiteOS. It has been reported development of the real-time operating system goes back as far as 2012 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenHarmony
OpenHarmony (OHOS, OH) is a family of open-source distributed operating systems based on HarmonyOS derived from LiteOS, donated the L0-L2 branch source code by Huawei to the OpenAtom Foundation. Similar to HarmonyOS, the open-source distributed operating system is designed with a layered architecture, consisting of four layers from the bottom to the top: the kernel layer, system service layer, framework layer, and application layer. It is also an extensive collection of free software, which can be used as an operating system or in parts with other operating systems via Kernel Abstraction Layer subsystems. OpenHarmony supports various devices running a mini system, such as printers, speakers, smartwatches, and other smart device with memory as small as 128 KB, or running a standard system with memory greater than 128 MB. The system contains the basic and some advanced capabilities of HarmonyOS such as DSoftBus technology with distributed device virtualization platform, tha ...

POSIX
The Portable Operating System Interface (POSIX; ) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. POSIX defines application programming interfaces (APIs), along with command line shells and utility interfaces, for software compatibility (portability) with variants of Unix and other operating systems. POSIX is also a trademark of the IEEE. POSIX is intended to be used by both application and system developers. As of POSIX 2024, the standard is aligned with the C17 language standard. Name Originally, the name "POSIX" referred to IEEE Std 1003.1-1988, released in 1988. The family of POSIX standards is formally designated as IEEE 1003 and the ISO/IEC standard number is ISO/ IEC 9945. The standards emerged from a project that began in 1984 building on work from related activity in the ''/usr/group'' association. Richard Stallman suggested the name ''POSIX'' to the IEEE instead of the former ''IEEE-IX''. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unix-like
A Unix-like (sometimes referred to as UN*X, *nix or *NIX) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like Application software, application is one that behaves like the corresponding List of POSIX commands, Unix command or Unix shell, shell. Although there are general Unix philosophy, philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux, FreeBSD and OpenBSD. These systems are often used on servers as well as on personal computers and other devices. Many popular applications, such as the Apache HTTP Server, Apache web server and the Bash (Unix shell), Bash shell, are also designed to be used on Unix-like systems. Definition The Open ...

Smartwatch
A smartwatch is a portable wearable computer that resembles a wristwatch. Most modern smartwatches are operated via a touchscreen, and rely on mobile apps that run on a connected device (such as a smartphone) in order to provide core functions. Early smartwatches were capable of performing basic functions like calculator watch, calculating, displaying digital time, translating text, and playing games. More recent models often offer features comparable to smartphones, including apps, a mobile operating system, Bluetooth and Wi-Fi connectivity, and the ability to function as portable media players or FM broadcasting, FM radios. Some high-end models have cellular capabilities, allowing users to make and receive phone calls. While internal hardware varies, most smartwatches have a backlit Liquid-crystal display, LCD or OLED electronic visual display and are powered by a rechargeable lithium-ion battery. They may also incorporate GPS navigation device, GPS receivers, digital cameras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Software Development Kit
A software development kit (SDK) is a collection of software development tools in one installable package. They facilitate the creation of applications by having a compiler, debugger and sometimes a software framework. They are normally specific to a hardware platform and operating system combination. To create applications with advanced functionalities such as advertisements, push notifications, etc; most application software developers use specific software development kits. Some SDKs are required for developing a platform-specific app. For example, the development of an Android app on the Java platform requires a Java Development Kit. For iOS applications (apps) the iOS SDK is required. For Universal Windows Platform the .NET Framework SDK might be used. There are also SDKs that add additional features and can be installed in apps to provide analytics, data about application activity, and monetization options. Some prominent creators of these types of SDKs include Google, Sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RISC-V
RISC-V (pronounced "risk-five") is an open standard instruction set architecture (ISA) based on established reduced instruction set computer (RISC) principles. The project commenced in 2010 at the University of California, Berkeley. It transferred to the RISC-V Foundation in 2015, and from there to RISC-V International, a Swiss non-profit entity, in November 2019. Similar to several other RISC ISAs, e.g. Amber (processor), Amber (ARMv2)(2001), SuperH#J_Core, J-Core(2015), OpenRISC(2000), or OpenSPARC(2005), RISC-V is offered under royalty-free open-source licenses. The documents defining the RISC-V instruction set architecture (ISA) are offered under a Creative Commons license or a BSD licenses, BSD License. Mainline support for RISC-V was added to the Linux 5.17 kernel in 2022, along with its toolchain. In July 2023, RISC-V, in its 64-bit computing, 64-bit variant called riscv64, was included as an official architecture of Linux distribution Debian, in its Debian version histor ...

Microcontroller
A microcontroller (MC, uC, or μC) or microcontroller unit (MCU) is a small computer on a single integrated circuit. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. Program memory in the form of NOR flash, OTP ROM, or ferroelectric RAM is also often included on the chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general-purpose applications consisting of various discrete chips. In modern terminology, a microcontroller is similar to, but less sophisticated than, a system on a chip (SoC). A SoC may include a microcontroller as one of its components but usually integrates it with advanced peripherals like a graphics processing unit (GPU), a Wi-Fi module, or one or more coprocessors. Microcontrollers are used in automatically controlled products and devices, such as automobile engi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BetaNews
eFront was an affiliate marketing network which purchased successful websites, such as '' Penny Arcade,'' SquareGamer, and BetaNews, and pooled traffic to those sites to command higher prices for advertising during an industrywide ad revenue slowdown. In 2001, there was a scandal when ICQ instant messaging logs between the CEO Sam P. Jain and other employees were leaked onto the internet through Fuckedcompany.com. The logs detailed activities such as not paying websites that had hosted their banner ads, sending legal threats to websites that spoke poorly of eFront, and threatening to "rape her and spit on her" (referring to a female webmaster angry about not receiving her check from the company). The logs also detailed how eFront attempted to hire, though never ended up paying, Something Awful founder and webmaster Richard "Lowtax" Kyanka, ostensibly to have him generate a positive buzz for the company.
