Who Reads This Blog? Traffic Breakdown by OS

Who’s reading this blog, and what are they running? I pulled month of site visitor stats to find out.

Can MacBook Neo Run Claude Code?

So in updating my MacBook Neo review with some additional stress testing and thermal testing, I came across some interesting results that begged the question: “Can it run Claude?” If you’re a gamer, that probably triggers the old “Can it run Crysis?” reflex. For those who don’t remember (or weren’t there), Crysis was the 2007 PC game that became the de facto hardware torture test. If your rig could run Crysis, it could run anything. It was a rite of

Claude vs ChatGPT vs Gemini for Coding: Testing Results

TL;DR: I ran the same 5 coding tasks through Claude Opus 4.6, OpenAI Codex CLI (gpt-5.3-codex), Google Gemini 2.5 Flash (sorry I did not have easy access to the newer models, but Gemma 4 was tested!), and two open-source models I ran locally: Gemma 4 31B and Qwen 3.5 35B. Claude’s code was the most production ready. Codex and Qwen tied for best code reviewer. Gemini was the cheapest. The open-source models scored A-, closing in on the paid tier.

Claude Code /buddy How to Preview, Hatch, and Reroll Your Terminal Pet

TL;DR: Claude Code v2.1.89 added /buddy, a virtual pet companion in your terminal. Your buddy’s body is deterministically generated from your account, and the personality generates permanently the first time you hatch it. Preview yours first with npx any-buddy current, but install Bun before you do (if you don’t already have it) Is This an April Fools Joke? I first noticed /buddy the least trustworthy way possible, by seeing it appear in Claude Code’s slash-command autocomplete on April 1. 😜

Claude code source code analysis

Source Archive Summary and Risk Analysis via ChatGPT 5.4 Thinking: Prepared from the src/ tree only. This version intentionally omits the file-by-file appendix and instead highlights what is structurally important, surprising, or concerning.   Scope analyzed: 1,902 files total, primarily TypeScript/TSX (.ts: 1,332; .tsx: 552). Largest areas: utils/ (564), components/ (389), commands/ (207), tools/ (184), services/ (130), hooks/ (104), ink/ (96). Overall impression: this is not a simple UI application. It is a full agentic CLI/runtime with shell execution, permission

Codex CLI + Claude Code: MCP Is 4x Faster Than the Command Line

TL;DR: OpenAI’s Codex CLI works best with Claude Code when you invoke it through MCP, not the command line. MCP calls return in about 3 seconds versus 13+ seconds for CLI on my dev environment, it avoids sandbox issues entirely, and keep everything inside your conversation. Here’s briefly how I set it up, tested various invocation methods, and landed on an optimized dual-AI workflow that works for my coding and research tasks. Why Codex When Claude Code Already Works? Claude

Gigabyte AORUS RTX 5090 AI BOX w/128GB Framework Desktop: Real-World AI Workstation Setup

5090 eGPU

Last year I was able to pick up a killer deal on a Gigabyte AORUS RTX 5090 AI BOX, an external GPU enclosure that packs a full desktop RTX 5090 (32GB GDDR7) into a compact box that connects over a single Thunderbolt 5 cable. My goal was to pair it with the Framework Desktop running AMD’s Ryzen AI Max+ 395 chip and see how well it worked as a portable AI workstation. Short answer: surprisingly well. The Setup: Framework Desktop

How I Used AI to Help Research Used Cars (and Saved $5,000 Over Carvana)

We recently bought a used 2025 Chevrolet Blazer EV RS AWD for $29,500 from a dealer in Muskogee, Oklahoma. It came loaded with heated and ventilated seats, Super Cruise, a head-up display, leather interior, and the RS sport package. The two Carvana listings we started with? $34,180 and $35,280 delivered for a much lower trim. That’s ~$5,000+ savings for a few hours research. Here is how we used Claude Code and Codex (AI coding tools from Anthropic and OpenAI) to
