Testing Four macOS Terminals for AI Coding: Which One Is the Best Companion for Claude Code?
April 06, 2026
If you’re like me and your daily development workflow already depends on AI coding agents like Claude Code and Codex, you’ve probably wondered: does the terminal itself affect the AI experience?
Went to Volunteer at a Nursing Home, Ended Up Making Two Friends

Tempted by 128GB RAM: The AMD AI Max+ 395 as a New Contender for Local LLM Inference
September 20, 2025
A few days ago, while scrolling through Twitter, I stumbled upon someone sharing AMD’s new AI Max+ 395 chip. Apparently it supports up to 128GB of memory, and several mini PC manufacturers have already shipped products based on it. As someone who regularly tinkers with local LLM inference, this immediately caught my attention. With today’s large language models routinely requiring tens or even hundreds of gigabytes, memory has always been the painful bottleneck.
From One Week to Half a Day: A Deep Dive into AI-Powered Programming Workflows
September 05, 2025
Hey there. I’m a full-stack developer who recently achieved a 10x productivity boost while building an EVM-based transaction signing review web app (React frontend + Solidity contracts) by systematically applying AI programming techniques. In this post, I’ll share the specific technical practices that made it happen, including tool configurations, real-world case studies, and reusable workflow templates.
