NetBSD is an open-source, Unix-like operating system known for its portability, lightweight design, and robustness across a wide array of hardware platforms. Initially released in 1993, NetBSD was one of the first open-source operating systems based on the Berkeley Software Distribution (BSD) lineage, alongside FreeBSD and OpenBSD. NetBSD’s development has been led by a collaborative community and is particularly recognized for its “clean” and well-documented codebase, a factor that has made it a popular choice among users interested in systems programming and cross-platform compatibility. ↫ André Machado I’m not really sure what to make of this article, since it mostly reads like an advertisement for NetBSD, but considering NetBSD is one of the lesser-talked about variants of an operating system family that already sadly plays second fiddle to the Linux behemoth, I don’t think giving it some additional attention is really hurting anybody. The article is still gives a solid overview of the history and strengths of NetBSD, which makes it a good introduction. I have personally never tried NetBSD, but it’s on my list of systems to try out on my PA-RISC workstation since from what I’ve heard it’s the only BSD which can possibly load up X11 on the Visualize FX10pro graphics card it has (OpenBSD can only boot to a console on this GPU). While I could probably coax some cobbled-together Linux installation into booting X11 on it, where’s the fun in that? Do any of you lovely readers use NetBSD for anything? FreeBSD and even OpenBSD are quite well represented as general purpose operating systems in the kinds of circles we all frequent, but I rarely hear about people using NetBSD other than explicitly because it supports some outdated, arcane architecture in 2024.

What is a flywheel? My first real life encounter with a flywheel was on a water well in South Africa. I was working at an orphanage where one of our projects was to provide a reliable water source. Because electricity was unreliable, we mounted a hand-powered pump. But we couldn’t use the kind of pump […]

China has developed OpenKylin, an operating system based on the open-source Linux platform, to reduce its dependence on US technology. OpenKylin 1.0, created by a community of approximately 4,000 developers, has been utilised in various sectors, such as finance, energy, and even in its space program. China's tech industry has prioritised developing an operating system that is not dependent on US technology, and OpenKylin is one of several under development that could replace Microsoft's Windows and Apple's MacOS. Notably, the system provides reliable fundamental software services and ensures security in critical areas such as government affairs and finance.

An international team of computer science researchers has identified serious security vulnerabilities in the iOS - the operating system used in Apple's iPhone and iPad devices. The vulnerabilities make a variety of attacks possible.

A method for sharing peripheral devices in dual operating systems for an electronic device having at least one peripheral device is provided. The method includes: receiving a setting value for the peripheral device under the first operating system from a user; activating a second operating system; transmitting the setting value to the second operating system; and switching from the first operating system to the second operating system, wherein the second operating system sets the peripheral device with the setting value and enables the electronic device to operate under the second operating system.

A system for protecting an electronic device against malware includes a memory, an operating system configured to execute on the electronic device, and a below-operating-system security agent. The below-operating-system security agent is configured to trap an attempted access of a resource of the electronic device, access one or more security rules to determine whether the attempted access is indicative of malware, and operate at a level below all of the operating systems of the electronic device accessing the memory. The attempted access includes attempting to write instructions to the memory and attempting to execute the instructions.

A hypervisor and one or more guest operating systems resident in a data processing system and hosted by the hypervisor are configured to selectively enable or disable branch prediction logic through separate hypervisor-mode and guest-mode instructions. By doing so, different branch prediction strategies may be employed for different operating systems and user applications hosted thereby to provide finer grained optimization of the branch prediction logic for different operating scenarios.

The present disclosure provides methods and apparatus for constructing a secure and flexible operating system. The presently disclosed system executes different user applications in different operating systems on different virtual machines. Each user application communicates with other processes via the hypertext transfer protocol (HTTP). In particular, each user application's user interface is implemented in a web browser that is running in its own operating system on its own virtual machine, and each user application interacts with the user interface by exchanging HTTP messages between the virtual machines.

An information processing apparatus includes a transmission unit transmitting a command of a second operating system to the second operating system when receiving the command via a communication path which communicates under a control based on a first operating system, an extraction unit extracting data for the second operating system by analyzing the command transmitted from the transmission unit, and a writing unit writing the data extracted by the extraction unit as data constituting file system metadata of the second operating system.

A system and a method are disclosed for batch execution of system calls in an operating system. In one implementation, a processing device configures a system call batching buffer table in a user space of an operating system, the system call batching buffer table including a plurality of system call units, associates a system call number with the system call batching buffer table, and issues a trap instruction to a kernel of the operating system to execute at least one of the plurality of system call units, the trap instruction including the system call number.

A method and a processing device may be provided for state management of an operating system and applications. A framework may be provided for separating behaviorless state information from code or instructions for executing a method. Applications may have instances of state information derived from, or completely different from, instances of state information of an operating system. Instances of state information for an application may be layered over corresponding instances of state information of the operating system, such that the application and the operating system may have different views of the instances of the state information. At least one policy may be defined, which may include rules for resolving conflicts, information for providing a merged view of data from multiple repositories, default values for instances of data, as well as other information. In various implementations, referential integrity of state information may be guaranteed.

An update system for the Linux operating system and a method thereof are disclosed. In the system and method, an update program can be obtained via distributed clients, to reduce a server's loading. When updating the operating system, allocation data on a user data sector is backed up and restored, so as to complete the update for the operating system. With the present technical features, the technical effect of backing up and restoring the allocation data on the user data sector, and reducing the loading of the server can be achieved.
