Sony sues Anthropic over staff piracy chats used to train Claude

Sony Music has filed a lawsuit against Anthropic, the AI company behind the Claude chatbot, alleging large-scale copyright infringement. Internal staff communications reportedly show Anthropic employees praising piracy platforms such as Z-Library to source song lyrics and other content for AI training. The lawsuit claims this unauthorized use of copyrighted music has directly harmed songwriters and rights holders. Sony argues the situation is made worse by the fact that AI-generated songs are now performing strongly on music charts. The case highlights growing legal tensions between major content owners and AI developers over training data practices.

A Step-by-Step Formula to Calculate Your Freelance Rate Accurately

Many freelancers set their rates by dividing a past salary by 2,000 working hours, a shortcut that routinely underestimates true costs and leads to earning less than in salaried employment. A more reliable approach works backwards from a target take-home income, accounting for taxes, business expenses, and the fact that only 55–70% of worked hours are typically billable. Freelancers must also factor in unpaid time spent on client acquisition, administration, and skill development, as well as the absence of employer-covered benefits like paid leave, pension contributions, and equipment. The recommended formula calculates required revenue by combining target income, tax rate, yearly costs, and a 10–20% profit buffer to cover payment delays and slow periods, then divides that figure by realistic billable hours. Applying this method almost always produces a higher rate than the salary-division shortcut, reflecting the true cost of independent work rather than an incomplete estimate.

Why ValidationError Is Just the Beginning, Not the End of Data Handling

A software developer argues that raising a ValidationError is only the starting point of data handling, not a complete solution. Writing from experience building a science-and-tech news digest, the author identifies three distinct validation boundaries within a single process, each requiring a different response strategy. Key decisions include rejecting the smallest possible unit of bad data rather than an entire batch, and sometimes accepting fabricated fallback values when the cost of doing so is well understood. The author also highlights that schema validation cannot address quantity-based failures, such as a feed dumping its entire archive in one poll. The central takeaway is that what a system does after detecting invalid data is a deliberate design choice, not a default outcome.

How to Prevent Split-Brain and Configure Quorum in Proxmox HA Clusters

Proxmox High Availability clusters are vulnerable to split-brain scenarios, which occur when nodes lose connectivity with each other and begin operating independently, risking data inconsistency and loss. A properly configured quorum addresses this by requiring a majority of nodes to be active before any critical operations are executed. Experts recommend deploying a minimum of three nodes, using redundant network connections, and adding a tie-breaker or witness node to resolve voting deadlocks. Common misconfigurations include skipping network and storage redundancy, and neglecting regular quorum health checks using tools like the pvecm status command. Balancing quorum size is also critical, as too few nodes compromise safety while too many can degrade cluster performance.

Why Secure, Scalable Middleware Is Critical for Edge Computing Deployments

The rapid growth of IoT devices, 5G networks, and real-time processing needs is driving a shift from centralized cloud systems to distributed edge computing environments. Edge computing moves data storage and computation closer to where data is generated, reducing latency, conserving bandwidth, and improving reliability. However, this architectural shift introduces significant security and management challenges, including an expanded attack surface, device heterogeneity, and data privacy compliance requirements. Middleware serves as the critical layer that connects applications, devices, and network services, enabling orchestration across complex and varied edge environments. Without well-designed middleware incorporating principles like Zero Trust security, robust identity management, and scalable orchestration, edge deployments risk becoming insecure and unmanageable.

Caitlin Clark's 2026 Net Worth Dwarfs Sophie Cunningham's by $17 Million

WNBA star Caitlin Clark is projected to reach a net worth of $20 million by 2026, far ahead of teammate and fellow player Sophie Cunningham, whose estimated net worth stands at $3 million. Clark's financial growth is largely driven by lucrative endorsement deals and commercial partnerships beyond her playing salary. Cunningham has accumulated her wealth primarily through her WNBA career and other business ventures. The comparison underscores the stark financial gap that can exist between players in the same league, reflecting differences in marketability and off-court opportunities.

Three GitHub Copilot Features That Can Genuinely Improve Developer Workflow

GitHub Copilot offers more than basic code completion, with several lesser-known features that can meaningfully boost developer productivity. The Inline Chat tool (Ctrl+I) lets developers generate code directly within VS Code without switching to a browser, helping maintain focus. The /explain command allows developers to quickly understand complex or inherited codebases by highlighting a block and requesting a plain-language breakdown. The /tests command automates unit test generation, including edge cases, by analysing a highlighted function and producing a testing suite suited to the developer's framework. Microsoft offers a free, hands-on Applied Skills pathway called 'Accelerate App Development with GitHub Copilot' for developers looking to learn structured prompting techniques and earn a verified credential.

How One Team Migrated Multiple Production Apps Using AI Without Breaking UX

A frontend team successfully migrated several production applications — some nearly a decade old — into a unified design system without disrupting the user experience users had come to rely on. The migration involved Angular codebases of varying complexity, including a finance platform with 70 admin routes and another with over 550 screens across 26 modules. Rather than starting with components, the team first extracted design tokens from existing stylesheets, assigning role-based names to visual values like colors and spacing to ensure consistency across apps. An AI agent was used to read, catalogue, and build components, while a pipeline involving token extraction, fingerprinting, clustering, and three-tier testing kept the process structured and auditable. The approach is described as framework-agnostic, meaning it can apply to any migration involving screens, components, and users with established behavioral expectations.
