  • In April, her 23-year-old son, Connor Lopez, was riding his motorcycle in Elk Grove when an oncoming car made a left turn and collided with him.

    Lopez, a piano teacher, died in the roadway. The district attorney’s office charged the driver, Harjit Kaur, with misdemeanor vehicular manslaughter — alleging that her failure to yield to oncoming traffic caused the fatal crash, court records show.

    She said she was talking to police and one of the officers kept referring to the case as “low-level.” “She took my son’s life, but that’s how they’re seen — low-level,” Lyman said.

    It really highlights something someone commented on another post: that we all suppress the knowledge that we’re driving two-ton death boxes. Like, it’s easy to say “she just made a turn without checking carefully enough,” and hard to rectify that with “she killed someone, however unintentionally.”








  • A bit more technical detail from greencarreports. I was wondering if 800v charging necessarily implies anything about motor voltage, and apparently it’s “sometimes”.

    GM’s GMC Hummer EV, for instance, runs at 400 volts, and each layer of its dual-layer battery pack operates in some ways as an individual pack. In 400-volt charging, the packs are connected in parallel, but for 800-volt charging a switch allows them to be connected in series—like the cells in a long, multi-cell flashlight—to take advantage of the higher voltage.

    That 800-volt “trick” permits the Hummer EV pickup, with its 205-kwh battery pack, to charge at 350 kw and gain nearly 100 miles of range in 10 minutes—despite its 400-volt system and its inefficiency compared to other EVs.






  • I am annoyed by Christmas before Thanksgiving, but the change doesn’t seem that egregious, just avoiding the case where it could be a week later than usual:

    in 1863, during the Civil War, Abraham Lincoln established the last Thursday of November as the official date for Thanksgiving to be celebrated each year. Following this tradition, every president thereafter declared a general day of Thanksgiving to be observed on the last Thursday in November. However, in 1939, during the Great Depression, November had five Thursdays, and the last one fell on November 30, which left little time for the Christmas shopping season. To address this concern, in August 1939, President Franklin D. Roosevelt decided to break from tradition and issued an executive order declaring that Thanksgiving would be celebrated on November 23 instead of November 30.

    Also it didn’t work:

    A 1941 Commerce Department survey found no significant expansion of retail sales due to the change.




  • There’s a full postmortem from AWS. One piece that stands out to me:

    due to the large number of droplets, efforts to establish new droplet leases took long enough that the work could not be completed before they timed out. Additional work was queued to reattempt establishing the droplet lease. At this point, DWFM had entered a state of congestive collapse and was unable to make forward progress in recovering droplet leases.

    That is, the load that resulted from the initial failure was not something the system was designed to handle, so it had cascading effects / required manual cleanup.


  • The installation is housed in what looks like a four-story prefabricated office building. Inside sits a massive stack of refractory bricks, which are heated to temperatures of more than 1,000 degrees Celsius (1,832 degrees Fahrenheit) by an adjoining 20-megawatt solar array. That heat is tapped to generate steam that is injected into oil wells to increase production — a job previously done by a fossil-gas-fired boiler.

    The project is something of a Faustian bargain. It will reduce carbon dioxide emissions by about 13,000 metric tons per year, said John O’Donnell, Rondo’s cofounder and chief innovation officer. But, of course, those reductions are in service of bringing more planet-warming fossil fuels to market.
