WE MOURN OUR CRAFT

AI is diminishing the programmer's craft, consuming human work, and reducing their role to mere oversight. Despite this, there is a career necessity for professionals to embrace these tools to remain competitive.

STOP GENERATING, START THINKING

A seasoned engineer is uneasy about the industry's rapid adoption of LLM-generated code. He's worried about outsourcing critical thinking, as LLMs are best at generation but not as great at reasoning like a human is.

TWO KINDS OF AI USERS ARE EMERGING. THE GAP BETWEEN THEM IS ASTONISHING

Martin sees two kinds of AI users emerging: power users who've embraced tools like Claude Code and are flying, and everyone else stuck on ChatGPT or Microsoft's enterprise Copilot — which is so bad that Microsoft itself uses Claude Code internally. The result is small teams with API access and coding agents massively outproducing enterprises trapped behind locked-down IT and legacy software.

WHY E CORES MAKE APPLE SILICON FAST

Apple silicon Macs achieve their high performance mainly due to their Efficiency (E) cores, which handle numerous background tasks, rather than solely relying on Performance (P) cores. Immediately after startup, E cores are heavily used for processes like Spotlight indexing and initial backups, leaving the P cores largely free for user applications. This architecture is managed by macOS's Quality of Service (QoS) system, which prioritizes foreground tasks for P cores and restricts background tasks to E cores, even when P cores are idle.

THE CLOUD AGENT THESIS

Cloud agents like Devin shift AI coding from local pair programming to organizational delegation. Running on remote infrastructure, these tools allow non-engineers to trigger tasks via Slack or Jira. This model scales capacity asynchronously, moving the primary bottleneck from code generation to automated review.

DEBUGGING WITH AI: CAN IT REPLACE AN EXPERIENCED DEVELOPER?

This dev tested Claude on three real React/Next.js bugs ranging from easy to hard. It aced the simple one, half-fixed the medium one (but introduced new issues), and completely failed the tricky one, confidently going in circles with wrong fixes. AI is a great first pass for standard bugs, but knowing when to stop prompting and start thinking is the real skill.

(AI) SLOP TERRIFIES ME

AI's ability to produce merely "good enough" software (or "slop") might create widespread user apathy, ultimately leading to the demise of quality software craftsmanship.

A CASE OF THE REVERSE IVORY TOWER

Platform engineering creates a reverse ivory tower when rigid abstractions distance infrastructure from developer reality.
