Here is the current US map with green showing the highest percentage of feverish people in March and April, blue showing May, and red showing June so far, to the 8th.
Notice California (e.g. Alameda County)
and Florida (e.g. Pasco County)
seem to be heating up in May/June (red and blue – orange), and western Utah (e.g. Beaver County)
has come alive in the last, red week – June, that is. I wonder if anything is going on in these places.
By way of contrast, consider most of Texas (e.g. Nolan County)
which was particularly feverish (compared to other places in the US) only in May. That drop-off in Nolan County, Texas is peculiar, too. Neighboring counties have a similar, but not so dramatic drop-off. Probably some peculiarity of data processing. … Or is it? Dum, dum, dum, dummm. Suspense!
This Corona Virus thing is, ignoring dead people, a lot of fun.
Well, because it’s so interesting. The progression of the disease is interesting, the reactions to the disease are interesting, and speculations about the post-virus future are interesting.
One interesting thing is the quantity of blather from the babble-world. Where are exceptions to misstatements, lies, confusion, and overall silliness?
One exception seems to be a company named Kinsa. They sell an Internet connected fever thermometer. $30 and $50. Currently sold out.
But, talk about perfect timing: Kinsa has data for much of the US showing when people were, and are, running fevers. Their data correlates pretty closely to flu season.
So, come Covid19, they moved fast and created https://healthweather.us. This web page shows in color and graphically which counties in the US have been affected by fevers and when, post February 16th.
The good, the bad, the ugly:
The Good: A couple minutes in the Firefox Web Developer says the data underneath the web page is remarkably clean and accessible. (OK, they’ve made breaking changes to the data a couple times in the last few days, but life is tough. Boo. Hoo.)
The Bad: Starting Feb 16? Why not Nov 1, 2019? I know why. But why?
The Ugly: Sorry, Tuco. You’re written out of this script. It’s a pretty web page.
Can the web page and data reveal outbreaks of fever in near real time? Kinsa sure hopes so.
As it turns out, the famously big US Covid19 outbreak (NY city) does show up in Kinsa’s data.
But, it remains to be seen what happens over the next few weeks as people wander out of stay-at-home. Thermometers don’t inherently pay attention to political spin, and don’t inherently serve to confuse. So, I’m rooting for Kinsa.
Now, this is all very nice, but what does it lead to?
Well, look at the orange/red line in the NY County image above. Notice its shape – its profile. Call that shape the “fever profile”.
I was clicking around some counties on the web page and noticed an odd thing: Most counties had a fever profile from February to May that looked like neighboring counties. Like, say, county A had a spike of fevers around March 17th, and so did bordering counties B and C. Not counties two states over, though.
But, sometimes there seemed to be sharp transitions between one county and the next with respect to their curves. Maybe my imagination. Maybe not.
I wanted to see the whole country’s county-time fever profile similarities at a glance. If two counties had a similar fever profile/curve from February through today, the two counties should look similar in a picture. And if their fever profiles were different, they should look different.
So, I whipped up a program to color counties based on the total fever-percentage-of-people numbers in 3 bands of time. E.g. Feb 16 to the end of February. The first half of March. And the third band for mid-March to the present. Then the larger the totals a county has in fever percentages in each band, the brighter a color is. The first band is red. The second, green. And the last, blue.
And, here is a picture of the US with counties colored based on fever percentage profiles as of today:
It looks like if you really didn’t want a fever, you should have been in a dark area – Arizona, New Mexico, or the Knoxville Tennessee area. That latter area is quite the surprise.
And if you like Covid19, you wanted to be in the bright blue (mid-March and later) Florida or the New York City areas. Don’t forget to be old!
If you want the flu (in red February), go north-central (ND, WI, MN, northern MI, … or … Canada?).
If you do like your body hot, go to where the colors are bright: downstate Illinois, Indiana, western Kentucky, and Missouri. Maybe Ohio. Or maybe California! Though in California a hot body could be taken two ways.
Here is a picture based on the fever percentages minus what Kinsaexpected them to be given historical trends:
Bright New York is pretty clearly where the unusual fever has been. And I love the West Virginia hole in the picture. Examining the (Fever – Expected) profile for a county there:
shows they dodged the flu.
Another bright spot I didn’t expect was downstate Illinois. The bright purple says they probably had a bit more flu and Covid19 than Kinsa‘s expectations. Or something.
You want movies? You got ’em:
Percentages of people running a fever stepping “today” from February through May:
All in all, it’s been a fun program to write. It shows the fever profile of the county your mouse hovers over so you can quickly see the profiles of lots of counties in a geographical area. I’ve found that handy and kinda informative.
This script simply takes Facebook posts off screen if they contain, in text form (sadly not in images), any of a list of words.
It’s not heavily tested, to say the least. Which is to say, I tried it a couple times.
I made it easy to add or delete banned words. Non-programmers can change the script if they can find it on their disk and save it as a text file from WordPad or a better text editor.
The results are nice. My feed is now pleasant. Again. “Never do yourself what a computer can do for you,” so the computer now lets me see the real news un-flooded by noise. (If this post makes it to Facebook, I can’t write “f*** news” or the script will make the post invisible to me!)
Oh. Here’s the whole script as of this moment:

Twenty some years ago my right hand became frozen around a mouse. It took the left hand to pry the mouse from my … hand.
Too much Minesweeper.
So, on the principle of “Never do yourself what a machine can do for you.“, I wrote a program to play the game. On screen. Mouse clicks and all.
And after watching expert mode being solved in 7 seconds a few times under Win 3.1, Minesweeper became boring and I stopped playing it. (No. The program did not use the cheat mode. It played fair.)
Fast forward some years.
I wrote a program to solve Spider.
It didn’t help. I’ve still spent too much time on that game. But the program did find only a couple of impossible-to-win games out of 32 thousand dealt. That was informative.
Fast forward some more years.
I wrote a Sudoku program to stop myself from playing that game, uncompelling and bite sized though the game was. It was a fun program and is handy to find impossible and incompletely initialized / ambiguous games (e.g. at sudoku.com). But it didn’t satisfy.
The program looks at the screen(s), finds boards, solves them, and plays them using mouse clicks and keys to enter the numbers. Though the program is incomplete, it’s pretty satisfying. Perhaps that’s why at one point many years ago I said that my job was to automate my job. And perhaps that’s why I’m not among the robotic hand-wringers of today. It’s simply fun to watch machines do what they do best.
As can be clearly seen by the octal values, this is a scan of the mylar tape of the Super Wrinkle boot loader for the APS-73 Computer used in Autologic typesetters.
Super Wrinkle, if I recall, was the ultimate boot loader – a worthy successor to the famous Wrinkle loader. Super Wrinkle required the minimum possible switch toggling to be read from the tape reader. Once it overwrote the toggled instructions, it read a more complex, generic, non-hacky loader. This had to be done after any power cycle / reset / program failure / hardware glitch.
The alternative to toggling in the instructions to read an infinite number of (Super Wrinkle) bytes from the tape reader was too expensive for everyday computer use. We’re talking $27 for a mighty, 256 byte ROM chip. That was back when $27 was $27, mind you. One customer built such a device out of discrete diodes to save the cost. The word was it was quite a monstrosity.

Python 3 is in the spot where it changed just too much that it broke all our code and not nearly enough that it would warrant upgrading immediately. And in my absolutely personal opinion Python 3.3/3.4 should be more like Python 3 and Python 2.8 should happen and be a bit more like Python 3. Because as it stands, Python 3 is the XHTML of the programming language world. It’s incompatible to what it tries to replace but does not offer much besides being more “correct”.
I really like Python. Moved from Perl (for PC work) when CPU’s got fast enough for Python. The Python out-of-box was terrific.
But, Python 3 is another language. I can’t justify porting all my personal “library” code to another language. Some of the Python 3 stuff reminds me of C++ – puffiness for the sake of puffiness. If forced to go to Python 3, I’d evaluate what language to use as I did when moving from Perl.
After spending yet another several hours fighting the good fight, it seems like a good idea to note how to use rsync on a troublesome ssh connection – one that both requires a password and that is slooooow to get logged on.
First, the problem of the password is solved using sshpass. It allows you to put the password for the remote system in a file. The file, we presume, is stored in your ~/.ssh/ directory and has its permissions set so that only you, the user, can see it or do anything with it. In that way, it works like an ssh key file that you might tell ssh to log in with using the “ssh -i ...” command line option.
Second, to allow for a slow server, use something like this as an option to ssh:
ssh -o ServerAliveInterval=45 ...
That is, tell ssh to wait for 45 seconds for the slow server to get you logged in.
So the command line to get a connection to the server is something like this:
Excuse the horrid backslashes. They are for the browser window.
All well and good. But that command line won’t work under rsync. The connection will be made, then instantly dropped. And rsync hangs.
I presume the drop is something security-related in ssh.
Or maybe sshpass.
Whatever. rsync is unhappy.
But, here’s the deal: rsync will be happy if the connection is already made in another terminal, and you have configured ssh to allow connections to go through a “master” connection – that is, tell ssh to not log in normally, but to rather use an existing ssh connection.
You tell ssh to use an existing connection by putting the following in a ~/.ssh/config file (remember to set the permissions for everything in ~/.ssh for only your access):
For clean-up reasons, you put the sshpass command in a separate .sh file which we’ll call ssh_to_bonzo.sh.
So now you run that ssh_to_bonzo.sh script in a “SCREEN” – sort of a virtual terminal window!
Years ago, I daydreamed about a head’s up display for futuristic Instant Messaging. The display would show vital signs of the “buddy” you were monitoring. Such an intimate thing might help with communication.
Viewing this waveform from the CMS50E requires an HTML5-capable browser (Firefox / Safari / Modern phones / Webit / maybe IE9). I do not know how timely the waveform will show up from outside the house. It updates on localhost about once a second – roughly in time with the heartbeat beeping from the device.
The waveform just stays put if the “finger” is out. Who knows what will happen when the device is not connected to the PC that runs the server.
The “finger” is my left index toe.
The project got a little out of hand. The general idea is to have a generic server that makes it easy to stream line/point numbers out to arbitrary numbers of web clients to graph. I cut things short to get this thing on line.
