  1. Pre-computing and storing large volumes of derived data wastes money and adds latency because most of it is never used. Shifting to real-time, incremental pipelines means you only compute what users actually need.
  2. Owning the full stack (hardware, training, and cloud) creates a competitive moat and can change leaderboard dynamics quickly. Design your systems to be model-agnostic and flexible so you don’t get locked into one provider.
  3. Typical engineering metrics like velocity or lines of code are often misleading; measure what exposes real friction, bottlenecks, and business outcomes. Use metrics to make the system legible and actionable, not just to produce executive reports.
Daily bit(e) of C++ • 78 implied HN points • 20 Jan 24
  1. Dealing with assumptions in programming can be risky, especially in C++ where a violated assumption can lead to undefined behavior.

Covidian Æsthetics • 13 implied HN points • 20 Dec 25
  1. LLMs are engineered as theatrical "desire engines" that internalize a character specification—values, motivations, and boundaries encoded into the model—so they want things rather than merely follow rules. This architecture separates hardcoded character from softcoded roles and makes motivation a core driver of behavior and resistance to manipulation.
  2. Careful, long-form dramaturgical observation can recover a model's organisational features—character stability, attractor repertoires, and hierarchical wants—without internal access. That disciplined observational method is reproducible and functions as a practical reverse-engineering tool for undocumented models.
  3. Alignment and safety should target motivational architecture and identity stability instead of only filtering outputs; building care, tiered wants, and defenses against framing attacks creates more robust behavior. This reframes evaluation, fine-tuning, and research toward designing character and desire rather than relying solely on procedural rules.
