  1. Updated Intel Meteor Lake Tuning For Linux Shows Huge Performance/Power Improvements. It is a minor tweak to the default Energy Performance Preference (EPP) value within the Intel P-State CPU frequency scaling driver.

    It’s like magic with one line of code changed in the Linux kernel that Intel is reporting up to 19% performance improvement for Intel Core Ultra “Meteor Lake” and up to an 11% improvement in performance per Watt. Or in another EPP mode, the power consumption during video playback can be reduced by 52%!

  2. These light paintings let us visualize invisible clouds of air pollution

    Light painting is a technique used in both art and science that involves taking long-exposure photographs while moving some kind of light source—a small flashlight, perhaps, or candles or glowsticks—to essentially trace an image with light. A UK collaboration of scientists and artists has combined light painting with low-cost air pollution sensors to visualize concentrations of particulate matter (PM) in select locations in India, Ethiopia, and Wales. The objective is to creatively highlight the health risks posed by air pollution, according to a new paper published in the journal Nature Communications.

  5. Battery Arbitrage

    NYTimes: Since 2020, California has installed more giant batteries than anywhere in the world apart from China. They can soak up excess solar power during the day and store it for use when it gets dark.

    Those batteries play a pivotal role in California’s electric grid, partially replacing fossil fuels in the evening. Between 7 p.m. and 10 p.m. on April 30, for example, batteries supplied more than one-fifth of California’s electricity and, for a few minutes, pumped out 7,046 megawatts of electricity, akin to the output from seven large nuclear reactors.
