Summary Following last week’s fix for the power management performance regression affecting some Intel Chromebooks, Linux 6.18-rc4 brings a critical patch for CPU idle state management (cpuidle menu governor) to address another performance decline issue that has persisted since 6.17. This regression caused a performance drop of approximately 11% in multi-threaded throughput tests on desktop … Read more
Methods to quickly consume memory in Linux typically involve running programs that require a large amount of memory, such as compiling large software, running virtual machines, opening many applications simultaneously, or using specialized memory stress testing tools.You can also simulate memory pressure by writing large amounts of data to memory, for example, using the <span><span>dd</span></span> … Read more
The weighing sensor junction box (also known as a junction box or signal junction box) is a core component in the weighing system, connecting the weighing sensors to the weighing instrument. Its primary function is to aggregate, distribute sensor signals, and adjust angle differences.The stability and safety of junction boxes with or without surge protection … Read more
The demands of embedded development programming are ever-changing. To achieve system stability and code reusability, high cohesion and low coupling must be maintained.It is generally believed that time-consuming operations cannot be executed within interrupts, as this would affect system stability. For programs with an operating system, interrupt handling can be divided into two parts through … Read more
(This article is adapted from electronicdesign) Digital feedback control is widely used to manage various devices, collectively referred to as controlled devices (DUC), such as motors, temperature systems, servo actuators, system pressure regulators, and flow controllers. The goal of digital feedback control design is to establish the performance standards required for the Analog-to-Digital Converter (ADC) … Read more
Introduction: To stabilize the WordPress technology ecosystem, the Linux Foundation steps in. This Friday, the renowned Linux Foundation introduced a new method for distributing WordPress update plugins that are not controlled by any single party, aiming to “stabilize the WordPress ecosystem” after months of internal conflict. The FAIR Package Manager project is a response to … Read more
