If You Never Do Anything Else to Fix Your Prompts, Do This One Thing

Why do LLMs confidently invent APIs that have never existed in the history of the universe? It is not a memory defect. Agents hallucinated because they were committed to the prompt—and Fernando Flores solved the root cause in 1986.

GitHub Isn't Just a Remote Git Server: How Spoke Clusters, Fork Alternates, and Actions Runner Sandboxes Work Under the Hood

A visual, 10-minute deep dive into GitHub distributed architecture. Learn how Spoke clusters replicate Git objects, how fork networks share terabytes via alternates, how secret refs/pull/ branches work, and how ephemeral Actions runners authenticate with keyless OIDC.

What LLMs 'Know' That You Don't Know They Know: Stop Inventing Prompt DSLs and Ride 50 Years of Unix Pre-Training Gravity

Why did a 1976 Makefile (Part 3.6) and a 1983 Unix init.d directory (Part 3.7) outperform 2,000 lines of English prompt rules? Because prompt engineering is static symbol linkage against 50 years of pre-trained computer science canon.

Requests, Promises, Assertions, and Declarations: Rewriting Our AI Agent Workflow as a 1986 'Committed Speech' Machine

Why do 200-line agent prompts, Asimov's Three Laws, and sequential pre-landing checklists all fail the same way? How Fernando Flores's 1986 Committed Speech, Nuel Belnap's 1977 4-Valued Logic, and Tony Hoare's 1978 CSP turned our Makefile and init.d workflow into a self-healing Commitment Machine.

Surviving the 200k-Token Lobotomy: How Unix init.d and 'Memento' Made My AI Coding Agent Immune to Context Compaction

Why host auto-compaction silently lobotomizes long-running AI coding sessions, and how 1983 SysV init.d runlevel files, Memento tattoos, and fork/wait subagents let our orchestrator survive two 230k-token compactions mid-ticket with zero lost steps.

Your failover is a retry loop pretending to be resilience
