Thanks for the link. I traveled on the Cory Choeust multiple times during the late 80s, though not on Heard island test. Very interesting working on SONAR in the 80s, both on surface ships and subs. Riding alone in the conning tower of an SSN in Exuma sound was fun. And saw a full rainbow in north Atlantic

Seen similar benefits - many years ago applied GA's to schedule technicians to fix computers (based on location, part availability, skill set, etc) and also for manufacturing production lines (labor rules, parts, color changeovers, demand, margin)
Re:History of 1918 Flu Pandemic
on Friday January 31, 2020 @10:22AM (#22202369)
According to "The Great Influenza" by John Barry young people died due to cytokine storms. Essentially young people have a vigorous immune system that gave an aggressive attack. 1918 flu was unique in that the deaths was not just the very young and the very old (a U shaped distribution) but rather a W shaped distribution with the middle point being 20-40 age group
Also in the book - the "spanish" flu was called that since Spain was the only place with a free press at the time (e.g., US press was not free at the time) + massing of young men in US in camps - like Ft Devens. Flu traveled from overcrowded camp to camp and then jumped to local populations along rail lines (and then overseas as troops were shipped out) He describes it well, though would make a great visual as it moves from Boston to Chicago to NYC back into Providence/Brockton (which are just south of Boston). Transmission along rail (and shipping) lines.

RIP Tim. I remember reading his work (usenet) back in the late 80's/early nineties - he once told me of his early days at Intel and later invited me to join the cypherpunks list a very long time ago. Tempus fugit.

Go to web page and configure max security including nomorobo. I was getting a great deal of spoofed calls. Seems to have worked

Many options including blocking anyone not in your contact list. Also include spammer blocking service nomorobo. Comcast also allows nomorobo service for free.

Move your phone to ooma.com. service is fast and easy.
My phone bill dropped compared to comcast and I have eliminated spam calls.

The new version is very good for Chinese. It is giving me much more complex sentence structure.

I have had it for ten years. Eventually you don't hear it until you think about it. Mine is very loud at the moment. Just another sign of aging. Nature's own memento mori.
