“Foundation models” represent a breakthrough in artificial intelligence or AI. They are a new form of creative, non-human intelligence and promise to bring great benefits econ.st/3MB0ms7

Super interesting talk by Ralf Herbrich on how to predict the state of health of second life EV batteries. It's a similar approach to what we are doing at Allye so that we can power local communities and decarbonise the grid tele-task.de/lecture/video/…

Software engineering consists of hundreds of "it's so over" ⇔ "we're so back" micro-episodes per day. Perseverance is just as, if not more, important than sheer technical ability.

important point here: these systems are much better at doing tasks than jobs. and giving people better tools to do their work faster often leads to qualitative changes in what they can do. (of course, over the long run, we expect these systems will be able to do all of some of

CHART OF THE DAY: The new breed of European energy traders is making a fortune. The top firms, which typically took home together ~$100 million a year in net profits in electricity and gas, reaped ~$5 billion in 2022. My @Opinion long-read column is here: bloomberg.com/opinion/featur…

Teams need to focus on learning, not just doing. When teams focus only on getting a job done, they perform worse than teams that also spend time learning from each other. Groups should be encouraged to think about learning for the future, not just on what they are doing now.

As we are now in spring, it is time for a thread on price cannibalization of solar. Solar will be central as it is growing fast, much faster than anything else. Projections from SolarPower Europe (DC value): 2024: solar = 1x average load in EU (320 GW). 2027, almost 2x. 1/13

Google just shipped a new algorithm that “is able to double the profit of a container shipper, deliver 13% more containers, and do so with 15% fewer vessels.”

Congratulations to Mike Cannon-Brookes 👨🏼‍💻🧢🇦🇺, who just received government approval to build the world's largest renewable and storage project. Sun Cable is a preposterously large (24GW+) solar and wind farm plus an improbably long electricity cord. reneweconomy.com.au/sun-cable-plib…

1/ New paper nature! Discrepancy between human expectations of task difficulty and LLM errors harms reliability. In 2022, Ilya Sutskever Ilya Sutskever predicted: "perhaps over time that discrepancy will diminish" (youtu.be/W-F7chPE9nU, min 61-64). We show this is *not* the case!

Batteries just keep on getting cheaper and cheaper. The average price of lithium-ion battery cells dropped from $290 per kilowatt-hour in 2014 to $103 in 2023.

"Right boys, that's the end of coal in the UK for electricity." This was the moment Ratcliffe-on-Soar power station was shut down, bringing an end to the country's 142-year reliance on the fossil fuel. Read more: bbc.in/3ZKmyu8

I’ve been using Kubera for a few years now. It’s been super helpful to track savings rates and net worth over time! Highly recommended
