Why Grep Is Replacing Vector Indexes: RAG Isn’t Dead, It’s Evolving

The article dissects Claude Code’s LLM‑driven Grep search, showing how multi‑round tool calls replace static vector‑based RAG, presents ripgrep performance benchmarks, compares Claude Code with Cursor and Codex, and argues that zero‑index search is optimal for local code bases while larger projects still need indexing.

Why an Unindexed UPDATE Can Crash Your Business—and How to Prevent It

The article explains how running an UPDATE without an indexed WHERE clause in InnoDB under repeatable‑read can trigger full‑table next‑key locks that block other statements, halt the service, and how using indexed predicates, checking execution plans, enabling sql_safe_updates, or forcing an index can avoid the disaster.

How a Single FFmpeg Command Can Cut CDN Video Bandwidth Costs by 90%

An investigation revealed that a 1 GB MP4 video streamed to 2,500 users consumed 120 TB of CDN bandwidth because the file’s moov box was placed at the end and the audio‑video tracks were poorly interleaved, causing thousands of HTTP 206 range requests; moving the moov box to the file header with a simple ffmpeg command eliminated the excess requests and reduced bandwidth usage to the video’s actual size.
