Guide: How to Back Up and Share VHD Files Between Windows 11 and Kubuntu

·16 views

Developer Nnamdi Michael Okpala has published a technical guide on DEV Community explaining how to create, back up, and share Virtual Hard Disk (VHD) files between Windows 11 as a host OS and Kubuntu running on Oracle VirtualBox as a guest OS. The guide covers installing key utilities such as NSSM and Winget via PowerShell, and walks through creating a VHD using Windows Disk Management and assigning it a dedicated drive letter. It also details using Windows Volume Shadow Copy Service (VSS) to create periodic volume snapshots and automate backups through Task Scheduler. Additionally, the guide explains how to register a PowerShell backup script as a persistent Windows service using NSSM for continuous, automated protection. While focused on Windows 11 and Kubuntu, the methods are noted to be compatible with Windows 10 and other Debian/Ubuntu-based systems, making them broadly useful for cross-platform development workflows.

Custom Booking Platform or Off-the-Shelf Software? A Guide for Service Businesses

This guide helps service businesses decide between custom booking software and ready-made tools by weighing cost, fit, data ownership and growth. It recommends first mapping the current booking flow to find where work piles up. Standard off-the-shelf tools are presented as the better choice for typical flows because of their speed, lower price and easier maintenance. A custom platform is justified when unique business rules cause manual work, double bookings or lost jobs. The article also urges checking data export rights and who can maintain the system if the builder leaves.

How to Compare Cybersecurity Courses Before You Enrol

Choosing a cybersecurity course can be difficult for beginners, since many programs cover similar topics and advertise comparable tools. The article argues that price and promotional claims are not reliable guides, and that learners should check whether a course matches their goals. It recommends reviewing the syllabus for a logical progression through foundational subjects such as networking, operating systems, scripting and web security. Prospective students should also look for hands-on practice in authorised lab environments and assess trainer quality, course duration and pacing. Finally, it cautions that certificates alone should not determine a choice, since employers typically look for demonstrated understanding and applied skills.

REST, GraphQL or gRPC: A Quick Guide to Choosing an API Style

Many teams pick an API style based on past experience, which can lock them into a choice for years. The article argues the decision can be made quickly by answering three questions about your system. Who calls the API, how varied the clients' data needs are, and how much inter-service speed matters. Public-facing APIs point toward REST for its broad tooling and HTTP caching, while internal, performance-sensitive services suit gRPC. Multiple clients with differing data requirements make GraphQL worthwhile despite its added complexity.

How to set Claude Code's base URL for a relay and verify the relay really serves Claude

The article explains how Claude Code uses the ANTHROPIC_BASE_URL variable to redirect API traffic through a proxy, and how ANTHROPIC_AUTH_TOKEN and ANTHROPIC_API_KEY set the credential header. It notes that some providers route Claude Code to non-Claude models via the same mechanism, which Anthropic does not support through gateways. To check a relay, the author recommends behavioral tests rather than asking the model its identity, such as a Python tool called claude-relay-check that tests response format, prompt caching, and thinking-block signatures. A second tool, ModelTrace, estimates the model family from generated digit distributions but is described as only a hint. The piece is written by the operator of a relay, which the author discloses.
