by George Whittaker The speculation around a successor to the Steam Deck has stirred renewed excitement, not just for a new handheld, but for what it signals in Linux-based gaming. With whispers of next-gen specs, deeper integration of SteamOS, and an evolving handheld PC ecosystem, these rumors are fueling broader hopes that Linux gaming is entering a more mature age. In this article we look at the existing rumors, how they tie into the Linux gaming landscape, why this matters, and what to watch. What the Rumours Suggest Although Valve has kept things quiet, multiple credible outlets report about the Steam Deck 2 being in development and potentially arriving well after 2026. Some of the key tid-bits: Editorials note that Valve isnāt planning a mere spec refresh; it wants a āgenerational leap in compute without sacrificing battery lifeā. A leaked hardware slide pointed to an AMD āMagnusā-class APU built on Zen 6 architecture being tied to next-gen handhelds, including speculation about

by George Whittaker Introduction The popular penetration-testing distribution Kali Linux has dropped its latest quarterly snapshot: version 2025.3. This release continues the tradition of the rolling-release model used by the project, offering users and security professionals a refreshed toolkit, broader hardware support (especially wireless), and infrastructure enhancements under the hood. With this update, the distribution aims to streamline lab setups, bolster wireless hacking capabilities (particularly on Raspberry Pi devices), and integrate modern workflows including automated VMs and LLM-based tooling. In this article, weāll walk through the key highlights of Kali Linux 2025.3, how the changes affect users (both old and new), the upgrade path, and what to keep in mind for real-world deployment. Whatās New in Kali Linux 2025.3 This snapshot from the Kali team brings several categories of improvements: tooling, wireless/hardware support, architecture changes, virtualization/image w

by George Whittaker Introduction In the world of modern CPUs, speculative execution, where a processor guesses ahead on branches and executes instructions before the actual code path is confirmed, has long been recognized as a performance booster. However, it has also given rise to a class of vulnerabilities collectively known as āSpectreā attacks, where microarchitectural side states (such as the branch target buffer, caches, or predictor state) are mis-exploited to leak sensitive data. Now, a new attack variant, dubbed VMScape, exposes a previously under-appreciated weakness: the isolation between a guest virtual machine and its host (or hypervisor) in the branch predictor domain. In simpler terms: a malicious VM can influence the CPUās branch predictor in such a way that when control returns to the host, secrets in the host or hypervisor can be exposed. This has major implications for cloud security, virtualization environments, and kernel/hypervisor protections. In this article weā
by George Whittaker Introduction Modern computing systems rely heavily on operating-system schedulers to allocate CPU time fairly and efficiently. Yet many of these schedulers operate blindly with respect to the meaning of workloads: they cannot distinguish, for example, whether a task is latency-sensitive or batch-oriented. This mismatch, between application semantics and scheduler heuristics, is often referred to as the semantic gap. A recent research framework called SchedCP aims to close that gap. By using autonomous LLMābased agents, the system analyzes workload characteristics, selects or synthesizes custom scheduling policies, and safely deploys them into the kernel, without human intervention. This represents a meaningful step toward self-optimizing, application-aware kernels. In this article we will explore what SchedCP is, how it works under the hood, the evidence of its effectiveness, real-world implications, and what caveats remain. Why the Problem Matters At the heart of t
by George Whittaker Introduction After years of debate and development, bcachefsāa modern copy-on-write filesystem once merged into the Linux kernelāis being removed from mainline. As of kernel 6.17, the in-kernel implementation has been excised, and future use is expected via an out-of-tree DKMS module. This marks a turning point for the bcachefs project, raising questions about its stability, adoption, and relationship with the kernel development community. In this article, weāll explore the background of bcachefs, the sequence of events leading to its removal, the technical and community dynamics involved, and implications for users, distributions, and the filesystemās future. What Is Bcachefs? Before diving into the removal, letās recap what bcachefs is and why it attracted attention. Origin & goals: Developed by Kent Overstreet, bcachefs emerged from ideas in the earlier bcache project (a block-device caching layer). It aimed to build a full-featured, general-purpose filesystem co
