Going in for a myocardial perfusion scan next week. Should be interesting. I'm bringing my Geiger counter along to see if my radioactivity is detectable. It ought to be. We'll see.

Gawd, I love Python.
Just wanted to say that.

So Linux always has 26 different ways to do everything. (That's not a complaint.)
Having not worked in a "Linux shop" where programmers readily exchange tips and tricks, I've done Linux for the past 21 years by myself. And I continue to wonder what is the best way to do this simple thing? So I thought I'd throw this out here.
On a Raspberry Pi I have both Python 2 and Python 3 installed. For years I've only used Python 3. But the default command "python" runs Python 2. For Python 3 I have to use python3.
To reverse this situation I can create aliases in .bashrc. Is that the easiest / best way?

We feed the local bird population here in our back yard. Just did a little arithmetic and found we feed about 2-1/2 tons of bird feed each year. Hahaha. Holy crap.

And still at it. Hahaha. Tightened it up a bit more. It's now 2-strikes and the IP is blocked. Seems they have lots of IPs, though.. Iran Germany, Belgium, all over.
What they don't know is that even if they succeed in the bajillion to one password guessing game, they'll hit my own encrypted 2FA. You don't get to log in unless the app (that I wrote) on my phone says yes.

They're still at it. Never seen an attack this relentless.
Well, keep at it guys. You'll run out of IP addresses centuries before you succeed. Lol. (IP lockouts are permanent until I manually override.)

Three more lockouts while I was writing the above.
I sometimes wonder if I seem like a more interesting target because I have security so strictly enforced.

Interesting. Over the past half hour my server has come under heavy login-attempt attack and from lots of different "countries" -- Pakistan, Netherlands, Hungary, USA, India. It's probably that huge hacking operation based in Wyoming.
No worries, though. 3-strikes IP lockout and passwords are random strings. Still amusing, though because there are definitely more interesting targets than me.

Question regarding Android and call blocking.
For years I've used so-called whitelist call blocking. All calls are blocked except a list of about 20 numbers that will ring through.
There's an organization that has a bunch of different numbers, and the list of numbers sometimes changes, but the caller ID string for all of them is the same: Mountain State such-and such. Is there a way I can unblock the caller ID string so that all the numbers with that ID can ring through?
Seems this feature must exist. It's probably right under my nose and can't see it.

Yeah, I don't know what to say on this. The politicians are obviously grandstanding. "Oh look what we're doing!". At the same time they're shamelessly showing their constituents that they're out-of-touch numbskulls.
It's nonsense and can never work. Ridiculous.

Good fortune has always followed me around. I'm reminded of it tonight. I'm working on a design that involves a thermistor. Modern thermistors are marvels of accuracy and repeatability. Wonderful things.
So, in the 1960s I lived in the Hillcrest area of West Los Angeles. We also had a beach house in Venice Beach. Our next door neighbor was the Link family, as in the child actor Michael Link. Michael's father was a chemist and retiring. He gave his entire personal laboratory to me, which we transported to the basement of our house in West LA and I added chemistry to my studies. Tremendous fun, very educational, even though I didn't become a chemist. Fortunately, he chose someone responsible because, while I was a crazy youthful experimentalist, I wasn't crazy enough to kill myself. The lab included lots of supplies and plenty of very dangerous reagents. Like I said, fun. This was not a child's toy or chemistry set and I was determined to learn how to use it properly. I mainly focused on chemical assaying. As in you give me a rock and I'll tell you what it's made of.
At the same time, one of my parent's many friends was Dr. Samuel Ruben. He visited Los Angeles from time to time. He and I would hang out and discuss chemistry. When he wasn't around, he was at his lab in New Rochelle, NY and we corresponded by written letters. He was my chemistry mentor. At that age and education level, I was not yet qualified to understand all that he had done. As time went on, I learned more about who had been teaching me.
Which brings us back to the thermistor. Dr. Ruben was an expert in electrochemistry. He held around 200 patents including the invention of the modern thermistor. He also invented the dry electrolytic capacitor, the modern alkaline battery, the mercury battery, the tantalum capacitor... on and on. Ruben co-founded with Mallory the Duracell company.
So I'm getting a kick out of closing the loop and holding a thermistor in my hand tonight.

Funny story...
EV's are not a thing here in West Virginia, yet. I think I spotted a Volt one time a few years ago but am not sure. I did see a Rivian downtown about a year ago. But that's it.
Here it's RAM diesel pickups rigged for smoke, SUVs, and 1960's, early 70's muscle cars, fully tricked out, 3/4 race cams, open exhaust, being driven on the street. Doing a burnout on the street with a 60s muscle car is fine. The cops don't seem to notice. Hah. Wish I had my 'rod from the 70s again (a tricked out '67 Chevelle SS that I sold for 50 bucks because I was sick and tired of building engines and car & boat drag racing.) I'd kill to have my Chevelle again -- 10.94 in the quarter mile.
Anyway, never seen a Tesla...until a few days ago. Called for an Uber ride to escort a friend and her kid to the dentist and here rolls up a maroon colored car. Didn't pay attention to the type of car. Didn't care. Didn't seem unusual because the car was quite noisy with fan noise, etc. After riding for a minute I realized it was a Tesla.
The driver was an old guy like me and he had the heat turned up to like 90 degrees in the car. I didn't complain because the ride was just ten minutes. But there it was, a Tesla. It behaved like an ordinary car but the external noise was off-putting. I would expect silence from an EV, like the electric buses and trolleys I grew up around in Los Angeles 65 years ago. What's with all the noise? The thing sounded like the fans in a data center, which is why I didn't notice it was an EV until I got in and recognized the Tesla escutcheon plate.
Anyway, so I've finally seen a Tesla and ridden in it. I didn't have time to talk with the driver about his impressions, unfortunately. I was too busy talking with the person I was escorting and translating for. (She doesn't speak English).

Yeah... 66F in Northern West Virginia on November 20th.
The locals, all Trump supporters say, "Yeah. this happens every year."
Uh, excuse me, but, uh, no it doesn't. No it didn't. It didn't when I lived here 20 years ago. It didn't when you grew up here 70 years ago. You've never seen anything like this, yet you bury it and go with the "narrative". Climate change is a hoax.
They are SO deluded that they alter their memory of reality to match the narrative they've been brainwashed to believe. It's incredible to see, and a real education into human nature and how flawed many of us are.
No wonder Hitler had so many followers. No wonder "Reverend" Jim Jones managed to massacre 900 people, including people killing hundreds of their own children. Humans have some SERIOUS and very disturbing flaws when it comes to cult leaders.
Yes, climate change is a hoax. 60 degrees on Thanksgiving is "perfectly normal". (Not that I like the cold. Some do. I don't. But this is NOT normal and is very disturbing. The "damn it's cold" moment should have occurred a month ago. It still hasn't occurred.)
A month ago is when I should have had to bundle up to run an errand at midnight. But no need for that tonight. T-shirt and a ballcap is fine. On November 20th. In Northern West Virginia.
