Mission Engineering 07: Baseline First — Test Process Changes Before Buying Gear

This article demonstrates Mission Engineering principles by using a morning coffee routine to show how to establish a baseline, compare isolated process changes (pre-preparation vs. detailed recording), design a run matrix for experimentation, and define abandonment criteria before investing in new equipment.

How Windows XP Ran Any App by Lying to Them

Windows XP achieved legendary compatibility by using a hidden database of shims that lied to applications about the OS version and even emulated the Windows 95 heap manager, allowing broken apps to run unmodified while Microsoft prioritized user upgrades over blocking flawed software.

Frequent Minor GC? The Real Culprits Are Allocation Rate and Premature Promotion

This article explains why frequent Minor GC in Java applications stems from high object allocation rates or premature promotion to old generation, not heap size, and details generational collection mechanics, promotion thresholds, dynamic age judgment, and troubleshooting using jstat, GC logs, and AsyncProfiler to pinpoint allocation hotspots.

Mission Engineering: Steps Done ≠ Mission Accomplished — A Coffee Lesson

This article introduces Mission Engineering through a coffee-making analogy, emphasizing that completing steps doesn't guarantee mission success; it outlines a structured approach using a Mission Description Card to define goals, stakeholders, constraints, and success criteria, and advocates iterative experimentation over rigid processes.

Golden Spike: Connecting Valen to Rust Without C ABI for Cross-Language Generics

Evan Ovadia, creator of the Valen language, develops a "Golden Spike" plan to enable direct cross-language generics between Valen and Rust by embedding rustc as a library and patching the Rust compiler to hand off non-Rust types to the Valen compiler, bypassing C ABI limitations.

Java Interface Default & Static Methods: Evolution Tool or Maintenance Trap?

This article analyzes Java 8+ interface default and static methods, explaining their original purpose for backward-compatible interface evolution, valid use cases like optional capabilities and mixin-style derived methods, and common pitfalls including hidden assumptions, silent failures, fixed workflows that prevent customization, and binary vs semantic compatibility issues. It includes a real-world refactoring example for payment callback handlers.

Why the Creators of Linux, Python, Redis, Nginx & SQLite Are True Geniuses

The article argues that creators of foundational software like Linux, Python, Redis, Nginx, and SQLite are true geniuses due to their exceptional abstraction skills and system-level boundary control, illustrated by real-world cases where their minimal, convergent designs outperform modern complex solutions, and warns that over-reliance on AI tools erodes deep system understanding essential for solving hard production issues.
