Articles & Tutorials
On Rendering Diffs (21 minute read)
Traditional code review tools have performance and display issues when rendering large diffs. This article goes over a specialized CodeView component that uses an "Inverse Sticky Technique" for virtualization that allows for native scrolling without visual blanking. To handle massive datasets, CodeView implements optimizations like detaching parsed strings, pooling DOM elements, and offloading syntax highlighting to background threads.
You Must Fix Your Asserts (12 minute read)
Assertions define mandatory conditions for runtime safety and compiler optimization, but disabling these checks in production is a flawed approach that allows software to run under false assumptions and masks underlying logic errors. Instead, assertions should either be kept active to trigger a panic upon violation or used as compiler optimization hints, which is necessary for maintaining long-term project health and truly correct code.
What happens in the log when an app crashes as it starts up? (10 minute read)
Determining why a macOS application crashes immediately upon launch is possible by precisely timing the startup process and reviewing the resulting system log entries. Capturing the right data requires opening the app at a specific second and using specialized utilities to extract the logs generated during that brief window. Security-driven crashes are typically identified by specific code signing error numbers or Apple Mobile File Integrity failures, while translocation issues appear as long, temporary file paths.
Domain Expertise Has Always Been the Real Moat (4 minute read)
Agentic AI has shifted the main constraint in software development from the ability to write code to the critical ability to judge whether the system's output is actually correct. As a result, deep domain expertise in specific industries is now the most impactful professional advantage, as this knowledge allows for verifying complex logic that generalist engineers might otherwise not be able to validate.
Build agents, not pipelines (13 minute read)
Integrating LLMs into software follows two primary paths: pipelines, which use fixed logic for predictability and high-scale applications, and autonomous agents, which manage their own control flow. Agents are generally better for solving complex problems by dynamically gathering context and iterating through reasoning loops.
Backpressure is all you need (30 minute read)
Backpressure is an approach to using AI agents that avoids both low-quality code from unattended agents and the limits of simple autocomplete. It involves automated mechanisms like tests and linters that require the agent to validate its own output through a structured workflow.
It's Not Just X. It's Y (12 minute read)
LLMs mimic human reasoning using rhetorical devices like negative parallelism, which triggers AI detectors to flag natural human writing as machine-generated. This automated policing turns effective rhetorical structures into liabilities.
Buffer's API is here: the social layer for your stack (Sponsor)
Buffer's new API is generally available and free on every plan. Schedule and publish across Instagram, LinkedIn, TikTok, Bluesky, X, and more from one connection. OAuth, MCP server, and CLI included. [Try the API explorer]
Where Should Agent-Generated Code Live? (4 minute read)
The massive increase in AI-generated code requires a specialized, programmatic Git infrastructure designed for repository management and fast sandbox access rather than traditional human-focused collaboration platforms.
With Claude: Less Coding, More Testing (5 minute read)
Integrating AI coding agents shifts the software development process away from manual boilerplate writing toward a focus on testing, verifying logic, and gaining a deeper understanding of complex codebases.

Cloudflare Turnstile requiring fingerprintable WebGL (2 minute read)
Cloudflare Turnstile prevents users of privacy-oriented browsers from accessing websites by mandating the use of trackable WebGL fingerprinting to complete human verification challenges.
Why Ctrl+V won't paste images in Claude Code on WSL, with a fix (9 minute read)
Fixing the inability to paste images into Claude Code within WSL requires a multi-part workaround that converts clipboard images to PNG, manages clipboard synchronization issues, and uses a custom keybinding to bypass terminal shortcut conflicts.
