Talks kick off Monday between U.S. and Mexican trade officials.
The North American economies could agree to renew the
US-Mexico-Canada Agreement,
or USMCA as it is for another 16 years
— a prospect that appears unlikely.
Or they could keep working on ways to improve it;
Under a convoluted renewal process, they have until 2036 to reach an agreement
Much of this bustling cross-border commerce is duty-free, thanks to the US-Mexico-Canada Agreement, that Do…

Instead of digging a bit deeper into factors affecting housing affordability, news articles like this uncritically accept YIMBY's Leora Ross's “Thanks to years of advocacy at the state level to pass laws like AB 2011, housing proposals like these will bring thousands of homes to the Bay Area and make it easier and more affordable for people to live here.”
There are so many factors affecting affordability - and this is ignored. WHY?
Plans for nearly 4,000 homes over Saf…

The definitive chart for avocados. Especially when you're dumb enough to buy two bags worth. 🤦‍♂️

Gemini said

A humorous bar chart titled, "🥑 The Great Avocado Ripening Mystery 🥑". The vertical axis tracks the "Number of Ripe Avocados" (0 to 12), and the horizontal axis shows the "Day of the Week" from Mon to Sun.

A single large, dark green bar indicates that exactly 10 avocados are ripe on Thursday. A green downward arrow points to this bar with the label "PERFECT!". All other days show zero ripe avocados. A light grey arrow points to Tuesday with the label "TOO HARD". A dark reddish-bro…

Abstract: The focusing of particle beams for collider experiments is crucial for maximizing the luminosity and thus the discovery potential of these machines. In recent years, plasma wakefield acceleration has emerged as a leading candidate for achieving higher energy collisions with smaller facility footprints due to the large accelerating gradients in the plasma. This higher beam energy poses significant challenges for the final focusing system of the collider. Here, we discuss the various challenges of final focusing for TeV-scale plasma accelerators and propose possible solutions. Finally, we present the first design of a final focusing system for a 10 TeV linear wakefield collider, evaluate its performance, and discuss its shortcomings as well as improvements for future designs.

Content warning: sexual abuse by a historic figure

Cesar Chavez will get canceled for this and he should, but there are a gajillion things in this country named after enslavers like Washington and Jefferson. Interesting how some heroes are immune to cancellation and others are not
