Starting with the M4 and including the new M5 generations of Apple Silicon, macOS no longer offers or allows full-resolution HiDPI 4k modes for external displays. The maximum HiDPI mode available on a 3840x2160 panel is now just 3360x1890 (with a 6720x3780, instead of 7680x4320 backing store) - M2/M3 machines did not have this limitation. With this regression Apple is leaving users to choose between: Full screen real estate at 4k (3840x2160) with blurry text due to HiDPI being disabled. or ...

Configuration Agent rules - concise, scoped CLAUDE.md files that shape agent behaviour Sandboxing - constrain file access and network connections Permissions - pre-approve safe operations, hard-block dangerous ones Hooks - run shell commands before/after tool calls as a safety net Extend knowledge and capabilities Skills - dynamic knowledge acquisition with progressive disclosure Language servers - give the agent go-to-definition, find-references, and type checking MCP tools - external tool servers, used sparingly Workflow Plan before acting - read-only exploration and task definition Embrace starting fresh sessions - keep context clean Template out common commands - reusable prompts for common tasks ...

NVIDIA artificially restricts peer-to-peer (P2P) GPU communication to their enterprise cards. Turns out this is a software limitation, not a hardware one. I patched my drivers to remove it, hacked vLLM to take advantage of it, and got a 15-50% throughput improvement running Qwen 3.5 35b on dual RTX 3090s.

An observation on functional correctness without domain quality.

If you’re building MCP servers, you should be adding the ability to disable individual tools.

MCP DevTools - The one tool that replaced the 10-15 odd NodeJS/Python/Rust MCP servers I had running at any given to for agentic coding tools with a single server that provides tools I consider useful for agents when coding. The Problem The MCP ecosystem has grown rapidly, but I found myself managing many separate servers, each often running multiple times for every MCP client I had running, not to mention the ever growing memory and CPU consumption of the many NodeJS or Python processes. ...

Square Peg hosted event on June 20, 2025 where I demonstrated a basic version of my daily Agentic Coding workflow using Cline and MCP tools. What does it take to write enterprise-grade code in the AI-native era? Join Square Peg investors James Tynan and Grace Dalla-Bona for a live demo and Q&A session with three leading AI-native developers - Grant Gurvis, Listiarso Wastuargo, and Sam McLeod - and get a behind-the-curtain look at the workflows that enable them to ship faster, smarter, and cleaner code using tools like Cursor, Cline, and smolagents. ...

Picture this: A business leader overhears their engineering team discussing “vibe coding” and immediately imagines developers throwing prompts at ChatGPT until something works, shipping whatever emerges to production. The term alone—“vibe coding”—conjures images of seat-of-the-pants development that would make any CTO break out in a cold sweat. This misunderstanding is creating a real problem. Whilst vibe coding represents genuine creative exploration that has its place, the unfortunate terminology is causing some business leaders to conflate all AI-assisted / accelerated development with haphazard experimentation. I fear that engineers using sophisticated AI coding agents be it with advanced agentic coding tools like Cline to deliver production-quality solutions are finding their approaches questioned or dismissed entirely. ...

I follow a simple, yet effective flow for agentic coding that helps me to efficiently develop software using AI coding agents while keeping them on track, focused on the task at hand and ensuring they have access to the right tools and information. The flow is simple: Setup -> Plan -> Act -> Review and Iterate. Workflow Quickstart Outline of Setup -> Plan -> Act -> Review & Iterate workflow: ...
