Missile Command coded by Qwen 3.6 with Claude CLI using the local LLM

Wed, 22 Apr 2026 00:00:00 +0000

I wanted to try pointing Claude CLI to a local LLM and see how well it would work. My machine is running linux EndevourOS has the following specs:

Monitor     3840x2160 in 27", 60 Hz [External]
Monitor     3840x2160 in 32", 60 Hz [External]
CPU         12th Gen Intel(R) Core(TM) i9-12900KF @5.20 GHz 52.0°C
GPU         AMD Radeon RX 9070 - 48.0°C [Discrete]
G Driver    amdgpu
Vulkan      1.4.335 - radv [Mesa 26.0.5-arch1.1]

RAM         ●●●● 23.94 GiB / 62.60 GiB (38%)

I use llama-cpp to run the model locally. During this experiment I kept hitting the context limit. I bumped it pretty high but then again, I have plenty of memory.

Migrating from Ghost to Hugo using Claude

Sun, 05 Apr 2026 00:00:00 +0000

Decided to move my blogs from Ghost to using Hugo and generate a static website for the content. The reason for this was I don’t use all the fancy features of Ghost. I don’t do newsletters and Ghost requires an email account if people want to sign up for notifications. Plus I have to run a database for the content.

I started with creating an new directory and fired up Claude and started with this initial prompt.

Coding with Claude AI

Wed, 21 Jan 2026 00:00:00 +0000

So I wanted to see what AI coding can do and started claude with /plan

Make a clone of Bejeweled game to run on Linux

It laid out the requirements, made a to-do list and suggested Rust + bevy for the implementation. I agreed. It asked would you like me to build it and off we go.

Initial commit didn’t have tests, executed but the grid for the gems was offset. I looked at the code and figure the something was a miss with the layout and asked Claude

LazyVim setup for NeoTest and Native Node.js Test Runner

Sun, 28 Dec 2025 00:00:00 +0000

The simplest and most effective approach involves using the devastion/neotest-node plugin. Create a configuration file at ~/.config/nvim/lua/plugins/neotest-node.lua

Configuration

return {
  "nvim-neotest/neotest",
  dependencies = {
    "nvim-neotest/nvim-nio",
    "nvim-lua/plenary.nvim",
    "nvim-treesitter/nvim-treesitter",
    "devastion/neotest-node",
  },
  config = function()
    require("neotest").setup({
      adapters = {
        require("neotest-node"),
      },
    })
  end,
}

The configuration specifies neotest as the core framework with neotest-node as the adapter for Node.js test execution. All required dependencies are declared and initialized during plugin setup.

Gemini Coding

Sat, 20 Dec 2025 00:00:00 +0000

Continue to play with various AI’s and how to use them in code generation. Next up is Gemini. I installed gemini-cli and setup an API key on Google along with a billing account and limit. See https://aistudio.google.com

Next I decided to try something that isn’t common (to-do, note taking, etc) and build a Texas Holdem Poker API server. I wasn’t sure the best way to write prompts and have been reading some books on the matter. I decided to ask Proton’s Lumo AI with the prompt, “help me write a prompt to build the API for a texas holdem poker game”

LazyVim setup for NeoTest and Jest

Sat, 20 Dec 2025 00:00:00 +0000

The setup involves creating a plugin configuration file that leverages the neotest-jest adapter. Save the following to .config/nvim/lua/plugins/neotest-jest.lua:

return {
  {
    "haydenmeade/neotest-jest",
  },
  {
    "nvim-neotest/neotest",
    dependencies = { "haydenmeade/neotest-jest" },
    opts = function(_, opts)
      table.insert(
        opts.adapters,
        require("neotest-jest")({
          jestCommand = "npm test --",
          jestConfigFile = "jest.config.js",
          cwd = function()
            return vim.fn.getcwd()
          end,
        })
      )
    end,
  },
}

Key Components

Plugin Dependencies: The configuration specifies neotest-jest as a dependency for the main neotest plugin
Jest Command: Configured to use "npm test --" as the execution command
Config File Reference: Points to jest.config.js for test configuration
Working Directory: Dynamically retrieves the current vim working directory

NeoVim AI Coding Assistant w/Avante

Sun, 14 Dec 2025 00:00:00 +0000

Initial Setup & Claude Integration

The author explored integrated AI coding assistance within NeoVim using Avante, recognizing that vague prompts produce problematic outputs. After testing Gemini 3’s limitations with broad requirements, they configured Avante with claude-sonnet-4-20250514.

When tasked with generating tests for a registration route, the assistant “created a task list of 8 things to plow through and chugged on that for 5 minutes.” Test generation cost approximately $1.04. The assistant also refactored monolithic code, separating functionality into distinct files.

AMDGPU Ring Timeout / Minecraft Workaround Using Mesa Zink

Tue, 23 Sep 2025 00:00:00 +0000

Main Problem & Solution

The author describes encountering AMDGPU ring timeout issues with Minecraft on an AMD Radeon RX 6700 system. Rather than modifying kernel parameters, the solution involves leveraging Mesa’s Zink driver—a compatibility layer translating OpenGL calls to Vulkan.

Hardware Configuration

CPU: Intel Core i5-12400F
GPU: AMD Radeon RX 6700 (Navi 22, RDNA-2)
OS: EndeavourOS (Arch-based distribution)
Desktop: KDE Plasma (initially), later tested Cosmic and Hyprland
Display: Dual 4K monitors with Freesync support

Initial Setup

Required packages:

Linux amdgpu: ring gfx_0.0.0 timeout

Thu, 04 Sep 2025 00:00:00 +0000

Running Wayland and experiencing Minecraft issues with kernel 6.16.3-arch1-1. GPU timeout errors appeared in system logs indicating the graphics processor failed to complete tasks within expected timeframe.

Initial Problem

Kernel logs showed: ring gfx_0.0.0 timeout, signaled seq=7925632, emitted seq=7925634 with the graphics device requiring a complete reset to recover.

Hardware Configuration:

AMD Radeon RX 6700 (Navi 22)
12th Gen Intel Core i5-12400F
64GB RAM
KDE Plasma 6.4.4 on Wayland

Troubleshooting Process

The author identified a Mesa regression by running glmark2 benchmarks, which initially crashed the system.

Best Business Books for Inspiration

Sun, 24 Aug 2025 00:00:00 +0000

I have written business plans every year for fun and executed a few. These books inspire different aspects of running a company or starting a new one.

E-Myth: Revisited by Gerber

First epiphany business book is E-Myth: Revisited by Gerber. This book exposes the myth of “I started a business so I’m an entrepreneur!” It follows the pie maker starting a pie shop and making pies.

The core insight: they are a technician making pies, not an entrepreneur. By documenting routines for pie production and hiring staff to follow them, they become a manager. Eventually, documenting management routines creates a self-running company based on repeatable processes.

Setup a Self-Hosted Ghost Blog with Docker and Caddy

Fri, 22 Aug 2025 00:00:00 +0000

Ghost blogging platform offers simplicity, but email configuration presents challenges. This guide demonstrates deploying Ghost via docker-compose with Caddy as a reverse proxy.

Core Setup

The Ghost documentation provides foundational installation steps. Caddy can handle wildcard domain certificates through Let’s Encrypt for HTTPS security.

Email Configuration Options

Transactional Emails (signup/subscriptions):

Mailtrap free tier maintains your domain reputation
Gmail alternative available if you accept third-party domain indicators

Newsletters (bulk messages):

Mailgun offers a free tier suitable for low-volume blogs
Configuration requires editing config.production.json with SMTP credentials

Gmail SMTP Configuration

Generate a dedicated app password via Google Account security settings, then configure Ghost with these credentials in the mail section of your production configuration file.

Caddy, Wildcard Certs and Ghost

Fri, 23 May 2025 00:00:00 +0000

The Problem

Hosting multiple applications on subdomains requires a strategy for SSL certificates. The specific example involves deploying Ghost blogging software to blog.geoffcorey.com while redirecting the root domain to this subdomain. The setup uses wildcard Let’s Encrypt certificates to avoid generating separate certificates for each subdomain.

Cloudflare API Token

DNS configuration requires Cloudflare. The CaddyBuilds/caddy-cloudflare Docker image provides DNS challenge support for obtaining wildcard certificates.

Setup: Docker Compose & Caddy Configuration

docker-compose.yml

The configuration includes three services:

Snowflake: conversion of timestamp NTZ to UTC with offset

Thu, 17 Apr 2025 00:00:00 +0000

Problem

Code attempting to transform Snowflake timestamp_ntz values stored in America/New_York local format into UTC time with offset notation did not account for Daylight Savings Time.

Solution

ALTER SESSION SET TIMEZONE = 'America/New_York';
SELECT
    TO_TIMESTAMP_NTZ('12/15/2023 01:02:03', 'mm/dd/yyyy hh24:mi:ss') as mytimestamp,
    mytimestamp::timestamp_tz as orig,
    TO_VARCHAR(mytimestamp, 'YYYY-MM-DDTHH24:MI:SS.FF3-TZHTZM') as datetime_wrong,
    CONVERT_TIMEZONE('UTC','America/New_York',TO_TIMESTAMP_LTZ(mytimestamp)) AS converted_ts,
    DATEDIFF('hour', converted_ts, mytimestamp) as hourdiff,
    TO_VARCHAR(converted_ts) || '-0' || hourdiff || ':00' as datetime;

The key involves using CONVERT_TIMEZONE() with explicit source and target timezones, which properly handles DST transitions.
