Notes — Arun Prakash https://arunprakashg.com/blogs/ Notes written after the build: AI agents, wave planning, benchmarks, and the products behind them. en Sun, 04 Oct 2026 00:00:00 GMT weekly 1 Wave Planning, Packaged: The Claude Code Plugin https://arunprakashg.com/blogs/wave-planning-claude-code-plugin/ https://arunprakashg.com/blogs/wave-planning-claude-code-plugin/ Sun, 04 Oct 2026 00:00:00 GMT Wave planning is now a Claude Code plugin. It plans a build into waves, routes each phase to the cheapest adequate model, and runs every wave in parallel git worktrees with a gate before the next one starts. AI Agents Claude Code Open Source xposed: Sharing a File Shouldn’t Need an Upload https://arunprakashg.com/blogs/xposed-file-sharing-without-upload/ https://arunprakashg.com/blogs/xposed-file-sharing-without-upload/ Sat, 03 Oct 2026 00:00:00 GMT Right-click any file and get a public HTTPS link and a QR code. Nothing uploads: it streams from your disk, and the link expires after 24 hours. How it works, and what shipping 13 releases in 7 days taught me.

AI Agents Software Engineering Systems Design Research C# Was Losing to Node Because of a Logging Call https://arunprakashg.com/blogs/cross-language-backend-benchmark/ https://arunprakashg.com/blogs/cross-language-backend-benchmark/ Sat, 22 Aug 2026 00:00:00 GMT Adding Java and C#, giving all 10 services 4 real CPU cores instead of 1, and finding a default-logging handicap that was quietly costing C# half its throughput — three fixes that flip the whole comparison. Performance Go Java C# Rust Node.js Deno Benchmarking Bun and Deno Crush Node — Until the Work Gets Real https://arunprakashg.com/blogs/js-runtime-throughput-benchmark/ https://arunprakashg.com/blogs/js-runtime-throughput-benchmark/ Sat, 22 Aug 2026 00:00:00 GMT Benchmarking Express, Fastify, Bun, and Deno under a trivial endpoint and then a CPU-bound one, in identically resource-capped Docker containers, tells two completely different stories. Performance Node.js Bun Deno Benchmarking We Researched the Entire PC Building Market. Here's the Verdict. https://arunprakashg.com/blogs/pc-building-market-research-30-segments/ https://arunprakashg.com/blogs/pc-building-market-research-30-segments/ Sat, 22 Aug 2026 00:00:00 GMT 30 buyer types, 1,000+ sources. What actually matters when building a PC in 2026 — the prices, the value picks, and the mistakes almost everyone makes.
