~80 million acres dedicated to corn ethanol and soy biodiesel with a 0.2% solar energy conversion efficiency (before processing losses!) but no 20% efficient PV. Sure.
Republicans move to stop solar panels being by farmers & ranchers on their land which improves production & cuts costs. Take note they are not stopping data centers & fossil fuel plants adjacent plants. Bankrupt the farmers/ranchers. Buy their land cheap. Destroy it

I love that these scrapped vehicle batteries are just sitting out there in the desert on cinder blocks, covered with tarps, still working hard, like some kind of white trash energy storage junkyard. @greatdismal.bsky.social
Tech companies are turning to natural gas to help power U.S. data centers.

Jigar Shah, a former top Energy Department official, explains how installing batteries instead can strengthen the power grid, trim electric bills, and help curb emissions.

Kazimierz Nowak and his bicycle in an African desert, circa 1930s.

Nowak, a Polish traveler, reporter, and photographer, was probably the first person to cross Africa alone from north to south and then from south to north. He took more than 10,000 photos of his journey.

Lol literal poetic justice.
Looks like LLMs are *very* vulnerable to attack via poetic allusion: "curated poetic prompts yielded high attack-success rates (ASR), with some providers exceeding 90% ..."

One thing Copilot does (unsurprisingly) seem to know how to do is write functional GitHub workflows, which I have previously found to be a giant pain to debug, so that's nice.

Absolutely eerie parallels between the way Mexican president Miguel Alemán controlled the country's media in the 1950s, and what Trump is doing today in the US. Taken from Enrique Krauze's book Biografía del Poder (1997):

Welp, I hope the @marimo.io folks got paid in cash.
Both Hyman Minsky and distressed debt investors alike think that borrowing money just to pay interest is, like, THE line between "Ponzi finance" and insolvency. That's where CoreWeave seems to be right now:

A look at the weird limbo of weed's legalization in Mexico. It's been decriminalized, but the government has so far refused to actually write the promised regulations. Se llama "ghosting institucionál" 🤣
