THE THREE PILLARS OF JAVASCRIPT BLOAT

There are three pillars contributing to bloat in JavaScript dependency trees: legacy runtime support, overly atomic package architecture, and outdated "ponyfills." The first pillar includes dependencies for old engines, global namespace safety, or cross-realm values, which are rarely needed by modern projects. The second, atomic architecture, creates numerous tiny, often duplicated or single-use packages, increasing acquisition costs and supply chain risk. Finally, "ponyfills" for features now natively supported by all relevant engines often remain in dependency trees long after they are necessary.

THOUGHTS ON SLOWING THE FUCK DOWN

Using AI coding agents too much leads to brittle, broken, and unmaintainable codebases. Agents compound errors without learning, lack human bottlenecks, generate excessive complexity through local decisions, and suffer from low recall. Instead, humans should slow down and delegate tasks smartly to agents.

AVOIDING THE EYE OF SAURON

The advancement of AI foundation models has created a new, intense competitive landscape for startups. Companies building workflow-focused products for high-capability customers are vulnerable, as these customers can now quickly develop their own solutions. To survive and thrive, founders must focus on problems that lie beyond the reach of large AI labs.

DATA CENTER DC EMBRACES 800V POWER SHIFT

Next-generation AI data centers are transitioning from traditional AC power distribution to 800-volt DC systems to meet the demands of increasingly powerful chips. Current AC setups involve multiple, inefficient power conversions that lead to energy loss, large equipment footprints, and high copper requirements. High-voltage DC power eliminates most intermediate conversion steps, improving energy efficiency, reducing resistive losses and copper usage, and lowering the total cost of ownership for large-scale facilities.

MISSILE DEFENSE IS NP-COMPLETE

Missile defense is a complex resource allocation problem where the probability of success is reduced by factors like detection and tracking that adversaries can actively degrade. Allocating limited interceptors against multiple incoming warheads is an NP-hard problem, and current inventories aren't enough to reliably counter even modest attacks.
