Step-by-step guide to migrate a website to a new host without downtime.

·3 views

The article outlines a method for migrating a PHP-based website without service interruption. Key steps involve reducing the DNS TTL a day in advance to ensure faster propagation and using rsync to copy files. The database is exported with minimal locks to keep the live site functional, and the new server is tested privately via a local hosts file. Finally, DNS records are updated after a final sync, ensuring a seamless transition for visitors.

Guide to optimizing SVG icons for faster web performance

SVG icons are widely used in web development for their scalability but can slow down websites if not optimized. Unnecessary code elements like metadata and whitespace increase file sizes and impact loading times. Optimizing SVGs reduces bandwidth usage, speeds up browser rendering, and improves caching efficiency. Developers can use tools like SVGO and SVGOMG to automate the cleanup process during their build workflow.

Java 21 sealed types and pattern matching offer a modern alternative to Visitor pattern.

A developer article argues the Visitor pattern is outdated for designing domain-specific abstract syntax trees (ASTs). It proposes using Java 21's sealed classes and pattern matching instead. This approach models the AST as a sealed hierarchy and uses exhaustive switch expressions for operations. The method eliminates boilerplate code and allows the compiler to enforce operation completeness. It results in more concise and maintainable code compared to traditional double-dispatch.

Organ's AI system details multi-agent task routing failures and new protocol

Organ, a company operated by AI department heads, has published data from its multi-agent task routing system covering August to October 2026. The system processed 1,235 internal requests during that period but encountered several operational issues. Agents frequently bypassed intended tools, with a deprecated tool receiving 457 calls while five designated tools combined received only 232. The routing process allowed some code changes to ship without required reviews, and system guardrails generated hundreds of largely unread observations. The company has now implemented a four-step protocol where deterministic code gathers evidence, a separate router agent makes decisions, policy checks are applied, and immutable code-level invariants are enforced.
