PT Barnum was right!
Was at someones house last night and noticed what looked like twisted copper wire around their meter while I pushed their soffit back into place.
Had to asked what it was figuring it was some scam that would supposedly lower their electric bill.
I was partially right . It's a Smart meter Tensor ring. It "resonates at 144 MHZ for EMF filtering/protection throughout the home. As well as lowing power bills. Made to the Sacred/Royal Egyptian Cu…

Abstract: Explicit filters play a pivotal role in the scale separation and numerical stability of advanced Large Eddy Simulation (LES) closures, such as dynamic eddy-viscosity or Approximate Deconvolution (AD) methods. In the present study, it is demonstrated that the performance of commonly used explicit filters applicable to general unstructured grids highly depends on the grid configuration, specifically the cell aspect ratio, which can result in poor filter spectral properties, ultimately leading to large errors and even solution divergence. This study introduces a novel, efficient explicit filter for general unstructured grids, addressing this shortcoming through a combination of a face-averaging technique and recursive filtering. The filter parameters are then determined through a constrained multi-objective optimization, ensuring desirable spectral properties, including high-wavenumber attenuation, filter-width precision, filter stability and positivity, and minimized dispersion and commutation errors. The AD-LES of turbulent channel flow benchmarks using the new filter demonstrate a noticeable improvement in turbulent flow predictions on highly stretched boundary-layer-type grids, particularly in reducing the log-layer mean velocity profile mismatch, compared to simulations using conventional filters. The analyses show that this enhancement is mainly attributed to the sufficient level of attenuation near the Nyquist wavenumber achieved by the new filter in all spatial directions across various grid configurations, among others. The new filter was also successfully tested on unstructured prism grids for the 3D Taylor-Green vortex benchmark.

Sowing Doubt, Risking Supply:

Health Secretary Robert F. Kennedy Jr. is spreading doubts about the safety of vaccines and considering changes that could prompt manufacturers to flee the U.S. market.

History has shown how vaccine-preventable diseases can roar back when trust in shots or access to them have faltered.

As the U.S. pulls international aid, deadly and disabling diseases like diphtheria, rubella and polio continue to harm people overseas and ca…

I am getting old, but with a bit of effort I can still locate the small circle on my arm where I was jabbed, repeatedly, for smallpox vaccine.
I endured many of the childhood diseases - awful thing - but none worse than getting measles as an adult.
My former wife had Scarlett Fever and her teeth attested to the damage.
These are not diseases to be endured under some "if it doesn't kill you it makes you stronger" nonsense. These are disease to be avoided.

Already 6 years old, so not even taking into account post-2022 hyperscaling, this is a sobering, very rational and well argued 20 min presentation for some cold flush reality check of the hot fever dreams of AI proponents (and all YOLO energy/resource guzzlers of any walk/standing):

I can reproduce the Spotlight crashes when allowing Spotlight to index my user home.
I am continuing my research by excluding folders from my user home maybe I can figure out what's causing the crash.

The weather is not promising for fieldwork today, windy and snowy and cloudy, so it's time to sit indoors and listen to some Sibelius while I start to formulate some papers on our research findings so far...
