Introduction: The mass migration from legacy version control systems like Azure DevOps to GitHub represents a fundamental shift in how enterprises manage their software development lifecycle. This transition isn't merely about changing platforms but fundamentally rearchitecting development workflows, security postures, and collaboration models. As organizations increasingly standardize on GitHub, understanding the technical implementation details and security implications becomes critical for DevOps teams and security professionals alike.

Introduction: The embedded systems landscape is undergoing a radical transformation as modern microcontrollers achieve performance surpassing legacy desktop processors. This evolution necessitates a fundamental rethink of software architecture approaches, particularly regarding security implementations. The historical resistance to abstractions in resource-constrained environments is becoming increasingly untenable as system complexity grows exponentially. Learning Objectives: Understand how zero-cost abstractions can enhance security without performance penalties…

Valve has updated the Steam Client Beta with a major shift to a full 64-bit client on Windows 10 and Windows 11. Systems running 32-bit versions of Windows will continue receiving updates for the legacy 32-bit client until January 1, 2026, ensuring a transitional window for older hardware. Alongside the architectural upgrade, the update includes targeted fixes for Game Recording failures on specific NVIDIA GPUs and improvements to general stability. Steam Input receives expanded support for new hardware, including Nintendo Switch 2 controllers and GameCube adapters operating in Wii U mode with rumble.

Accounting software provider Netgain has unveiled a fixed asset tax depreciation solution for accounting firms, NetAsset Tax Pro, that the company says replaces outdated and costly legacy systems.

The nostalgic thrill of the 1980s is back in full force with the final season of Stranger Things, but behind the retro sci-fi fun lies a sobering reality for operational technology (OT) security. Just as Hawkins Lab’s clunky equipment opens a gateway to the “Upside Down,” outdated OT systems in critical infrastructure are opening doors to cyber threats that can wreak havoc on our essential services.

Introduction: In an era dominated by AI hype, a recent discourse within the cybersecurity community highlights a foundational truth: core systems knowledge remains the bedrock of effective defense. The legacy of Linus Torvalds, the creator of the Linux kernel, serves as a powerful reminder that deep technical proficiency in open-source operating systems is a superpower that pre-dates and underpins modern artificial intelligence.
