    Profoundly awesome thing for computational science: You can automatically get chi-squared contours with jax and inverting the Fisher matrix, with ONE function evaluation. Jax: github.com/google/jax Here is a paper explaining Fisher matrices. arxiv.org/abs/0906.4123

    For only the 2nd time ever, renewables met more than 75% of demand and carbon free sources (renewables & nuclear) made up 86% in ERCOT. Renewables could have provided more but were curtailed; note how the top of the cowboy hat curve is lopped off. More than enough for 100% today.

    I miss old academic twitter so much! It was great learning about conferences in real time and learning about new papers from friends and colleagues. What a loss!
