Ant-Like Persistence

I told you so.  Four months ago I told you so.  I told you to drop Whatsapp and switch to Signal in my article It is time to switch to a new end-to-end encrypted messaging app.  Now in January of 2021 lots of people are finally realizing they should switch to Signal.  

Please recall this article (August 23, 2020) in which I explain how to be smart about what kind of phone number to use as your user ID for Signal.

If you’d like to try messaging me with Signal, drop me a note at my email address with your Signal identifier telephone number and I will fire off a Signal message to you.

Yeah, I had Covid-19.  I’m fine now.  I’ll say a few words about how it went for me, but my reason for mentioning this is mostly to urge you to consider donating convalescent plasma (see blog article).  Continue reading “Yeah, I had Covid-19”

Hello blog colleagues.

A couple of days ago I went to a blood donation center and I donated 650 units of convalescent plasma.

Yeah.  I had Covid-19.  Continue reading “Donating convalescent plasma”

I imagine for most people, a file server is not the sort of thing that you have warm and fuzzy feelings about.  But hear me out.  Continue reading “Warm and fuzzy feeling about a file server”

(Corrected thanks to alert reader Jarek Markieta who pointed out that 1, 4 and 9 are squares of the first three counting numbers, not cubes.)

(Not one but two alert readers immediately pointed out my mistake about the metal from which the top of the Washington Monument is made — aluminum and not gold.  See comments below.  I have corrected this.)

What word may correctly be used to describe this object?  People call it a “monolith”.  That’s wrong.  People call it an “obelisk”.  That’s wrong. What can we call it? Continue reading “What to call it?”

I was puzzled and intrigued to learn about something called “the nasal cycle”. Maybe it will turn out that most of my readers already knew about this, but I certainly did not. It turns out that in all mammals, including humans, there is an autonomic mechanism by which a first nostril’s breathing path constricts for a while and the second nostril’s breathing path remains open. Then after a while the second breathing path is the path that gets constricted and the first breathing path opens up. In most healthy humans, this back-and-forth constriction usually takes place in a cycle of about five hours, with two and a half hours during which one nostril gets preference and another two and a half hours during which the other nostril gets preference.  Or, maybe I am just making this up!  Could there be such a thing and people would not already know all about it?
