Current Perspective on COVID-19 Coronavirus (from someone else)

I'm copying the following from a post by someone else - a fellow named Rex, on a mailing list named Twister - because Rex is one of those rare people who basically is always sensible and informative when he speaks - always worth listening - and I'm hungry for some clear perspective on COVID-19, and think others might appreciate it, too. And, selfishly, have an easy place to find it for my own future reference.

 To not get too carried away, though the guy is smart he's does not omniscient, and things might develop differently than he expects. I find this helps me get a sense of proportion on what is currently known, but not more than that.

 March 3, Rex:
It's a virus which hopped from animals to people.  Happens now and then.Kinda flu-like symptoms, but greater severity, especially for older orunwell people.  There have been influenza strains that are approximately asbad, but not for a long time.  (The H1N1 outbreak of 1918 probably hadslightly lower mortality rates, but it may have had higher infectiousness,so overall impact may be similar--too early to tell, really.) 
Because of the severity, a lot of countries will put forth quite a lot ofeffort to try to contain the virus, but this will ultimately not besuccessful because the poorer countries can't afford effectiveprecautions.  It also seems doubtful that a vaccine will be ready beforeapproximately everyone has caught it, despite the efforts of wealthycountries to stop and/or slow the spread. 
Most people will be fine, and the health care systems will be strainedseverely but are unlikely to break entirely.  It may be the leading causeof mortality for one year.  (Upwards of 10% for 80+-year olds.)  It maycontribute to a recession, which is kind of overdue anyway.
I don't know enough virology to hazard a guess as to the efficacy of avaccine once available. 
It's also a good litmus test for which countries have authoritariantendencies--if they get into worse trouble because they try to manage PRbefore managing the virus, that's good evidence.

Blogger silently drops comments submitted by Safari in embedded-comments mode

We've noticed that comments submitted from Apple Safari (Mac or iPhone) are dropped without any notification if the blog is set with Comment location = Embedded. Having set it to Pop up (I think), it worked. We're going to try some more tests. That's what this post is for! From the comments testing we discovered some useful things: Using Comment location = embedded: Is necessary to enable replying to specific comments. Comments posted from Safari (laptop or iOS) are silently dropped. It looks to the person posting the comment that it went through, but the blog moderator sees no sign of it at all. Using Comment location = Pop up or Full page: Inhibits option to reply to other comments – no comment threads Enables comments from Safari The trade-off is clear. Losing comments from people who think they submitted them successfully is not acceptable. Particularly from a prominent browser (currently estimated to be a bit less than 4% of users). I just hate to lose comment threadin

A Contemplative Movement Online Score

Barbara Dilley developed a shared dance/meditation practice called Contemplative Dance Practice – CDP, a "dancer's meditation hall". I've been exploring adaptation of this score for online sharing. The aim is to share meditation and movement across the gap of social distancing. (See below the score description for online meeting logistics and further info about the practices.) (The framing of this score is a work in progress, continuing to change. Revision information is at the bottom.) Score Description The score is divided into sections. At the beginning of each timed section the facilitator says which section it is and arranges for a bell to sound at the beginning and the end of that section. Opening Circle : Time for brief introductions / check-ins and to review the outline of the score (essentially, the bold headers below). Meditation: 15 minutes for stillness . In the original score the participants share sitting meditation. We invite whatever meditat

An Accumulation Score for Ensemble Movement

Many people are acquainted with the notion of conventional musical scores, which describe what musicians should do to perform a song/piece. No matter how specific the instructions, it can't be perfectly complete. It's always necessary for the person performing the score to make choices of their own - particular emphases and cadences and whatever it is that establishes what the performer expects is best to realize the piece. At the other end of the spectrum, improvised pieces can have scores also. Those scores don't generally use standard notation, but instead describe some parameters of the piece in some way, leaving many aspects up to the participants. This accumulation score is one such movement improvisation score. I don't recall where I first learned about it, nor do I recall the exact instructions I received in the various times I've been exposed to it. The ones below are my own take on it, but I expect they're similar to those that many others have also
