Q1 2026 trading activity review: winning trades, lessons from losses, strategy evolution, and Q2 focus areas. Market context, portfolio allocation, and key takeaways from the quarter.
Instead of one AI assistant doing everything, I built a team of 3 specialized agents: Manager (requirements), Verifier (code review), and Coder (implementation). Complete with workflow automation, tool restrictions, and thread-only enforcement!
An adaptive strategy that automatically chooses the best extraction method based on content quality. Text extraction when possible, screenshot+OCR when needed. 26% better success rate, 85% cost savings!
A recent DNS vulnerability affects Pi-hole installations. Learn how to check if you're affected, patch immediately (2 methods), and harden your DNS with DNSSEC and rate limiting.
Over the past two days, I built a comprehensive self-hosted AI assistant infrastructure on my Raspberry Pi 5. This post documents everything: N1 Clash proxy, Pi-hole, Dashboard, Uptime Kuma, Cloudflare Tunnel, and more!
Most Pi-hole tutorials recommend Google DNS or Cloudflare. For users in China, this creates a dependency on proxies. Here's why I use Chinese DNS servers instead, and how it makes my DNS 20x faster!
Cloudflare Tunnel needs proxy to CONNECT but NOT for traffic. Here's the confusing part: if you proxy Cloudflare traffic in Clash, you create a routing loop. Here's how to fix it!
