• 11:16, 6 July 2026 Dex talk contribs created page Don't Use Windows Server 2016 for Android Development (Created page with "Windows Server 2016 remains a capable platform for infrastructure services, Active Directory, IIS, SQL Server, SharePoint, and laboratory environments. However, it is increasingly unsuitable as a primary platform for modern Android development. As Android Studio, Gradle, Java, and associated tooling evolve, they increasingly depend upon operating system functionality that was not available when Windows Server 2016 was released. This can result in obscure compatibility i...")

Business Continuity focuses on keeping critical business functions operating during disruption, while Disaster Recovery focuses on restoring systems, applications, and data after a failure has occurred. A successful organisation does not eliminate risk. Instead, it understands its risks, prepares for likely failure scenarios, and develops...")

Rather than presenting resources and generating ''Access Denied'' messages when users attempt to open them, ABE ensures that users only see resources they are authorised to access. ABE is commonly used in Windows File Services, SharePoint environments, and enterprise conte...")
• 06:35, 6 July 2026 Dex talk contribs created page Least Privilege Access (Created page with "'''Summary:''' Least Privilege Access (sometimes called the ''Principle of Least Privilege'' or ''PoLP'') is a security model that restricts users, systems, applications, and services to the minimum permissions required to perform their intended function. Rather than granting broad access "just in case", permissions are carefully assigned based on business need, operational responsibility, and security requirements. This reduces the impact of mistakes, limits opportuni...")
• 06:33, 6 July 2026 Dex talk contribs created page Defence in Depth (Created page with "'''Summary:''' Defence in Depth is a security strategy that uses multiple, independent layers of protection to reduce risk. Rather than relying on a single security control, organisations deploy overlapping preventative, detective, and corrective measures throughout their infrastructure. The approach assumes that any individual security control can fail, be bypassed, misconfigured, or become obsolete. By introducing multiple protective layers, an attacker who defeats o...")

This can create the impression that QR codes themselves contain special capabilities. In reality, a QR code is simply a method of encoding data. The apparent magic comes from the software that interprets the data and decides what action to take. == Context == Most people encounter QR code...")
• 14:15, 5 July 2026 Dex talk contribs created page Directory Synchronisation Strategies: From XCOPY to Rsync (Created page with "'''Summary:''' Directory synchronisation is the process of keeping files and folders consistent between two or more locations.

Understanding these differences is essential when supporting, demonstrating, or developing applications remotely on Apple hardware. == Context == Administrators and developers ac...")
• 14:08, 5 July 2026 Dex talk contribs created page JavaScript for Everyone (Created page with "'''Summary:''' JavaScript has evolved significantly since its introduction in the 1990s. Modern JavaScript development often assumes the availability of recent browser features, build pipelines, transpilers, package managers, and evergreen browser updates.
