Me an' Algernon – grappling with (temporary) cognitive decline

news.ycombinator.com Kent Beck 2025-09-28 15:00:54

Originally published May 20, 2015. Since then my cognitive function has made a fairly complete comeback, well except accounting for normal aging. I was reminded of this essay by my experience with augmented coding. That “normal aging” stuff left me without the patience to get set up for coding. With the genie, though, I’m happy to dive into most any project. It’s like wearing an exoskeleton but for my brain. The point remains—don’t take cognition for granted.

This is driven by the enhanced efficiency of modern solvers, which can today find globally optimal solutions within seconds for problems that were out of reach a decade ago. The versatility of these solvers allowed successful applications in many areas, such as transportation, logistics, supply chain management, revenue management, finance, telecommunications, and manufacturing.

As summer arrives, people are turning on air conditioners in most of the U.S. But if you’re like me, you always feel a little guilty about that. Past generations managed without air conditioning – do I really need it? And how bad is it to use all this electricity for cooling in a warming world? If I leave my air conditioner off, I get too hot. But if everyone turns on their air conditioner at the same time, electricity demand spikes, which can force power grid operators to activate some of the
