AI & Dev Tools
Editor and model comparisons, agents, and free or self-hosted coding assistants.
- Cursor vs GitHub Copilot: Which AI Code Editor Wins?
Desk comparison of Cursor and GitHub Copilot on autocomplete, chat, codebase indexing, pricing, and when Copilot is still the better fit.
- ChatGPT vs Claude vs Gemini: Which AI Is Best for Developers?
Desk comparison of ChatGPT, Claude, and Gemini for code generation, debugging, context windows, docs, and API cost — not an IDE bake-off.

Desk notes on ten genuinely usable free-tier coding tools — and what each one is bad at.
- Best Open Source AI Coding Tools You Can Self-Host
Desk notes on Ollama, Continue, Tabby, and open coding models you can run on your own GPU — privacy, VRAM, and when cloud is easier.
- How to Configure Roo Code Custom Modes: Optimize Your AI Developer Agent
Desk notes on Roo Code custom modes: tool-group ACLs, when not to enable execute, and how the listing differs from Cursor Composer or Cline defaults.
- Best AI Tools for Refactoring Legacy Code
Desk workflow for AI-assisted legacy refactoring: understand first, add tests, then incremental multi-file edits — not a wholesale rewrite.

Desk notes on Claude, Copilot Chat, Cursor, Amazon Q, and Gemini for stack traces, multi-file bugs, and cloud-platform debugging.
- The State of AI: What Developers Need to Know
Desk notes on what actually changed for developers in 2026: editors vs models vs agents vs hosts, and what to check before you switch stacks.
Local Models & Hardware
Run models on your own machine, then size GPUs and laptops for that stack.
- How to Run LLMs Locally: Ollama, llama.cpp, and Hardware Requirements
Install Ollama or llama.cpp, size VRAM for 8B–70B models, and wire a local coding stack into VS Code or Cursor.
- How to Use a Local LLM in Cursor with Ollama (2026 Tunnel Setup)
Desk notes on Cursor plus Ollama: HTTPS tunnel, what still stays in Cursor cloud, and when to skip a GPU buy.
- How to Run DeepSeek-R1 Locally with Ollama: The Complete Developer Setup
Run DeepSeek-R1 distilled models with Ollama, size VRAM, and point Cursor or VS Code at the local API — not a localhost Cursor hop.
- The Best GPUs for Running Local LLMs in 2026
VRAM tables and desk buying notes for local LLM inference: 8B–70B sizing, NVIDIA vs AMD vs Apple Silicon, and current-card price searches.
- Best Laptops for Developers in 2026: Specs, Use Cases, and Picks
Desk notes on MacBook Pro, ThinkPad X1, Framework 13, Zephyrus G14, and MacBook Air — memory, Linux, and local-AI fit, not listing copy.
- Building AI Agents: Architecture Patterns and Practical Examples
Desk notes on client-tool agent loops: allowlists, iteration caps, and when a framework invoice is the wrong buy.

- How to Set Up an AI Pair Programming Workflow That Actually Works
Desk notes on AI pair-programming setups: which seat to buy for navigator vs driver vs ping-pong, and when stacking Cursor plus a chat plan is wasted.
- How to Automate Unit Testing with AI Tools
Desk notes on when AI-generated tests lock behavior versus when they just snapshot the current implementation.
- Automating Code Reviews with AI: A Practical Integration Guide
Desk notes on AI pull-request review in CI: severity contracts, and when a review SaaS is the wrong buy.
- AI Code Generation Security: Best Practices Every Developer Needs
Desk notes on AI-generated code risks: injection, secrets, and what to check before you ship — or buy another scanner.
- How to Reduce AI Hallucinations in Code Generation
AI coding tools sometimes invent APIs that do not exist, reference wrong library versions, or produce subtly incorrect logic. Here is how to catch and prevent it.
- TypeScript Best Practices: Beyond the Basics
Move past any and basic types. Advanced TypeScript patterns for type safety, maintainability, and developer experience.

- Vector Databases Explained: When You Need One and How to Choose
Desk notes on pgvector, Chroma, Weaviate, Qdrant, and Pinecone — and when a new SaaS is the wrong buy.
- API Rate Limiting: Implementation Strategies and Best Practices
Protect your API from abuse and ensure fair usage. Token bucket, sliding window, and distributed rate limiting patterns.
Web & Infrastructure
Where to host what you build and how to ship it through CI/CD.
