I've been finding that physics simulations that tax a GPU are very taxing on a virtual system in KVM when you don't have a GPU passthrough.

NVidia created their own Docker image that allows this seamlessly. I worry though that the Docker infrastructure is to be cavalier about the signing process for what gets to be part of an official image. For example Nvidia does not sign their docker images.

The power of Open Source technology is the ability to delve deeply into the guts of a released project to see what's happening behind the scenes. That usually requires not just downloading the completed packages and looking at the code, but replicating the process used to create the packages and seeing if you get the same thing on an independent system.

Ubuntu does an excellent job of setting a trust chain that can be tracked all the way down to the original code both with hashes and signatures. You can follow the base code signature and hashes all the way up to the final signed/hashed distribution.  How about docker?

A WERNER 9V alkaline battery on a 5m string of 12V IP68 LED lights.

Tests to see if the battery + lights would work well for lighting up a buoy at night for a moonlit race and be completely powered by a 9V battery.

Initial Voltage of Battery = 9.7 V

Since we've seen the 7 +/- 2 day lag in spikes in Italy and WIsconsin it's interesting to see if you can see those same patterns on a county by county basis. A good comparison is Racine vs Dane Counties.

2020-05-30: While Italy has the standard exponential growth and standard decay of a pandemic, in WI you can see the effects of the lawsuits and protests that ended the curbs weeks too early. Each event has a spike at about 3-7 days after the event and a second one 10-14 days after the event.

2020-05-13: The science of spreading disease states that the more exposure to a virus, the more likely you are to be infected. And we see that clearly in COVID-19 as those counties most likely to participate in the "Spread the infection" protests became those counties with the largest increase in per-capita infections.

While Italy has shown the standard exponential growth and natural decay, WI has had a series of spikes growing from 15 to 79 new infections per capita per million.... (click to read more)

You can see the results of the spread the infection protest in MI in the graph below. The end effect that MI has been pushed back to peak infection rate levels.  As you see in the graph - since MI is 10 days ahead of WI, one would expect a similar peak after the WI spread the infection protest on 2020-04-24

This is an update from /covid19/wi_vs_others ... We saw the uptick in the WI +6 days after the WI primary, but now there was a "spread the infection protest" in Michigan which will have an equally predictable result.
