How to Migrate WordPress to Next.js Without Tanking Your SEO Rankings

·1 views

Migrating a WordPress site to Next.js involves far more than fetching posts via the REST API — preserving SEO requires maintaining existing URLs, metadata, redirects, sitemaps, and images. The core principle is that nothing Google already indexes should change unless deliberately improved, since altering URLs, content structure, and templates simultaneously destroys accumulated ranking signals. A complete pre-migration inventory of every published URL, rendered content, metadata, and internal links is essential before writing any Next.js code. Standard WordPress WXR exports are often inadequate for page-builder-heavy sites, as they omit rendered HTML and key SEO fields. Tools that capture fully rendered content and structured SEO data can serve as a reliable source of truth throughout the migration process.

SQL Advanced Functions Explained: Numeric, String, Date, and Conditional Operations

A technical guide published on DEV Community outlines advanced SQL functions that go beyond basic data selection and filtering. The article categorizes these functions into numeric, string, conditional, and date types, covering operations such as FLOOR, CEILING, ROUND, ABS, and MOD. It explains practical use cases, such as using FLOOR to calculate full hours from minutes and MOD to distribute data into groups or identify even-numbered rows. The guide also highlights key differences across database engines, noting that SQL Server uses LEN() instead of LENGTH() and handles ROUND differently from PostgreSQL. Special attention is given to NULL handling in string concatenation, warning that operator-based joins can silently return NULL when any component value is missing.

Developer Running 10+ AI Coding Agents Finds Human Attention Is the Real Bottleneck

A developer experimenting with parallel AI coding agents — including Claude Code, Codex, and Kimi — found that running over 10 agents simultaneously across multiple machines created an unexpected problem: managing human attention rather than compute resources. While the agents handled tasks like feature implementation, bug fixing, and code review concurrently, the developer spent increasing time manually checking each terminal session to determine agent status. Constant context-switching between sessions proved mentally exhausting, as each switch required reconstructing the task history and next steps for that agent. Tools like tmux help keep sessions organized and persistent but do not address the deeper challenge of prioritizing attention across many autonomous processes. The experience points to an emerging workflow gap in AI-assisted development, where visibility and attention management have become as critical as the agents' technical capabilities.

Read-Only Database Access Can Still Crash Your App if AI Workloads Go Unchecked

A read-only Model Context Protocol (MCP) server connecting to PostgreSQL can still destabilize production systems despite lacking write permissions. Exploratory queries, wide aggregates, and concurrent retries compete with application traffic for the same CPU, memory, connections, and I/O resources. Experts warn that 'read-only' defines mutation rights, not workload safety, and AI-driven database traffic should be treated as a distinct workload class. Best practices include dedicated connection pools with hard limits, statement and row caps, replica routing with freshness contracts, and deadline propagation. Silently expanding the pool or falling back to the primary under load are considered unsafe responses; visible, bounded admission control is recommended instead.
