This summer I installed Solar. And I didn’t find a good app that combined solar with dynamic prices. So I build it into mine: Energy prices compares your personal solar prediction with live dynamic prices for NL, and tells you when to run appliances. apps.apple.com/nl/app/energi…

these are.. human level good.
These two Mythos-written stories actually move me in a weird way. They're both clearly about the shape of Claude's own experience, and they're each kind of a beautiful expression of it

I feel sorry for @matt_levine 's weekend plans.. (his newsletter is amazing..)
BREAKING: Tesla has released its 2025 proxy, and it includes an unprecedented $1 trillion pay package for Elon Musk (if he meets all objectives). If Elons wants to receive the full award, he will need to create $7.5 trillion in shareholder value, making @Tesla an $8.5 trillion company. The plan spans 10 years. The additional shares Elon could receive would push his stake in Tesla to at least 25%. There are 12 tranches, with each worth about 1% of the company. The first one would come at a $2 trillion market cap. To capture each tranche, Elon not only has to meet a market cap milestone, but one of the operation milestones as well. Meaning if Elon doesn't deliver, he gets paid nothing, making this a very shareholder friendly one. Elon will have to hold the new shares after he receives them for 7.5 years. Tesla: "The 2025 CEO Performance Award similarly challenges Elon to again meet a series of even more aspirational goals, including operational milestones focused on reaching Adjusted EBITDA targets (thresholds that are up to 28 times higher than the 2018 CEO Performance Award’s top Adjusted EBITDA milestone) and rolling out new or expanded product offerings (including 1 million Robotaxis in commercial operation and delivery of 1 million AI Bots), all while growing the company’s market capitalization by trillions of dollars."

I build an app ⚡️ this Saturday at 12 power was 50% cheaper than at night. So I built Energypricing: widgets that show the best time to use power, right on your lock/home screen. apps.apple.com/nl/app/energy…

I built a tool to backtest dynamic energy pricing savings. Analyzes your HomeWizard data against 2023-2024 market prices, calculates savings & optimal battery size. All local - your data stays private. Try it: dynamicpricing.panman.org

Astrophysicist and Nobel laureate Subrahmanyan Chandrasekhar used to travel 80 kilometers every week from the Yerkes Observatory to the University of Chicago, where he taught a course attended by only two students. When asked why he spent his time this way, the professor replied that they were very good students. In 1957, Lee Tsung-Dao and Yang Chen-Ning were awarded the Nobel Prize in Physics. The course taught by Subrahmanyan Chandrasekhar became the only course in history where all its attendees received a Nobel Prize.

I have a list of feedback items that I want to summarize to a few bullet points with counts. GPT is surprisingly bad at this, often repeating similar items and the counts are totally worthless. Any ideas / prompts I should try?
