RunPacer: A Smartwatch-Based Vibrotactile Feedback System for Symmetric Co-Running by Visually Impaired Individuals and Guides
Visually impaired individuals often require a guide runner to safely participate in outdoor running. However, maintaining synchronized pacing with verbal cues or tethers can be mentally taxing and physically restrictive. Existing solutions primarily focus on navigation or obstacle avoidance but overlook the importance of real-time interpersonal rhythm coordination during running. We introduce RunPacer, a smartwatch-based vibrotactile feedback system that delivers synchronized rhythmic pulses to…

Motivic Steenrod operations at the characteristic via infinite ramification
We construct motivic power operations on the mod-$p$ motivic cohomology of $\Fb_p$-schemes using a motivic refinement of Nizioł's theorem. The key input is a purity theorem for motivic cohomology established by Levine. Our operations satisfy the expected properties (naturality, Adem relations, and the Cartan formula) for all bidegrees, generalizing previous results of Primozic which were only know along the ``Chow diagonal.'' We offer geometric applications of our construction: 1) an example o…

Oh, and one can use bags of Holi powder (available via Amazon and elsewhere) to create giant rainbows on the FFOTUS parade route on the day before.

I am probably being muted left and right for going on a boost rampage, but hey, it's Friday. Mute me for a day, follow someone new for a lifetime.

"There was a recent 2024 study that showed us that individuals who survive an acute COVID-19 infection (...) on average will lose somewhere in the neighbourhood of two to six IQ points per infection."
"although your immune system can take on [a COVID] infection, you want to avoid testing it as much as possible because your body is sustaining damage with each infection that it survives."
Seriously, wear a mask 😷 .

Scientific evidence is painting an unsettling picture: COVID infections, even if mild or asymptomatic, may be causing long-term cellular and organ damage, as well as increasing your risk of developing long COVID.

It would be nice if the #upzoning plan didn't significantly reduce rear yard open space requirements - that removes valuable green space in the dense urban environment.
There are other approaches (great balconies!), but somehow I don;t see that playing out in San Francisco.
