Virtualization sits at the core of modern IT infrastructure. Without it, cloud computing would collapse, cross-platform software development would stall, and hardware research cycles would drag on for years. Among the hypervisors and emulators shaping this landscape, QEMU stands out for one critical reason: it is fully open source, free, and community-driven. With the release […]| System Administration

Hey everyone! As many have noticed, the PinePhone Pro is currently out ot stock on the Pine Store. Unfortunately we have to deliver you the following news: the PinePhone Pro is officially discontinued. We were told it didn’t sell well enough to keep production going. But the good news for current owners are that spare parts will still be made for up to two years, depending on demand. Meanwhile, the trusty PinePhone (A64) is still alive and kicking, and Pine Store plans to keep it rolling fo...| PINE64

The dictionary definition of the word “grift” is as follows: “to acquire money or property illicitly [https://www.merriam-webster.com/dictionary/grift]”. It may be a strong word, but also more or less encapsulates the regulatory ethos that’s governing cross-border technology businesses these days. The TikTok-Oracle deal flaunts this| Interconnected

An operating system is used to make our job easier when using graphics. In our instance, in addition to everything else. In this post, we will be writing a GPU (graphics processing unit) driver using the VirtIO specification. In here, we will allow user applications to have a portion of the screen as RAM--with what is commonly known as a framebuffer.| Stephen Marz
Input devices give our operating system the ability to accept mouse and keyboard inputs from the graphical user interface (GUI). We originally used the UART (universal asynchronous receiver/transmitter) for console I/O, but we're high class now--we have a GUI! So, we will use the virtio protocol to communicate with a mouse and keyboard.| Stephen Marz
