Performance issues in Rails applications frequently stem from five common culprits, which can usually be diagnosed and resolved with a practical checklist. Key changes can enhance response times by 5-10x, addressing the most significant bottlenecks with varying levels of effort required for fixes. The infamous N+1 queries are highlighted as a major performance killer, often resulting in excessive database queries and substantial delays. For instance, a homepage loading 50 posts might incur 51 database queries with N+1, slowing response

The content discusses the limitations of using Postgres' `NOTIFY/pg_notify` for tracking database changes in real-time, particularly in high-throughput environments. While `pg_notify` can be effective for small, less active tables, it can create a bottleneck in larger tables due to the single notification queue, causing a significant reduction in transaction throughput. The author suggests an alternative approach using the Postgres Write-Ahead Log (WAL), which records every change in the database and allows for improved

The text discusses the concept of non-human entities, particularly ships, being recognized as legal persons, a status commonly granted to corporations. This legal classification allows ships to be held accountable for their actions, such as accidents while docking, by enabling them to be impounded or have their property seized. Ships possess limited legal rights, akin to due process, including the ability to post bonds and seek trials. A notable aspect of maritime law is the "right of salvage," whereby a ship that successfully rescues another

Abigail Adegbiji is developing a voxel game engine that requires procedurally generated terrain, which involves sampling noise functions for height values. She explains the basics of different types of noise, starting with white noise, characterized by completely random values, resulting in a harsh, staticky sound when played. In contrast, brown noise, derived from Brownian motion, uses a random walk process that connects consecutive samples, producing a smoother and softer sound with an emphasis on lower frequencies. However, neither white nor
