Schitt's Creek
Schitt's Creek Season 1 Trailer
We watched the first couple of episodes this evening. They are only 20 minutes long. Very funny, with a full complement of wacko personalities.

CT Scanner
CT at max speed
I had a CT scan done once. From the shape of the machine and from the noise it makes, I deduced that the innards must be rotating around the hole in the center. It's nice to have some confirmation. The medical profession is a lot like NASA. All their technical explanations are designed for little children. It means getting any real information requires digging.

We sat down to watch season 2 of Wanted Monday night and ended up watching all 6 episodes and not going to bed till after midnight. Haven't watched any TV since.
Season 2 is a continuation of the story that started in season 1, except the McGuffin has inexplicably changed from a duffel bag full of cash to a safe deposit box key. There were some bone headed maneuvers early on that had me yelling at the screen, which annoyed my wife. So after two episodes I started drinking beer and after that the screw-ups didn't bother me as much.
Much of the story depends on blind, dumb luck and coincidences. Frigging unlikely, but it could have happened, and truth is sometimes stranger than fiction, so I'll give them a pass.
The two women are an unlikely pair. The older one has spent a lifetime keeping her head down and staying out of sight. The younger one lived a very sheltered existence, but when they get dumped in the shit they become each other's best friend. Very Thelma and Louise, except they don't kill themselves. They don't even die, and I appreciate that.
Big Fancy Rocket
Making Life Multiplanetary
I do wish Elon had given the BFR a different name. I use the F-word frequently, but I try to refrain from using it in public, and my wife gives me grief if I use it, or any other blue words in her presence. Expletives have their place, but if every other word out your mouth is a curse, you're not doing it right.
BFR v Airbus 380 size comparison |
The BFR is a big, new rocket project at SpaceX. It's going to be about the same size as an Airbus 380. It sounds like they intend to make it reusable, like their Falcon rockets, that is the boosters will return to their launch pad and safely land under their own power. This is quite a trick involving navigation, control and fuel management.
Falcon Heavy & Starman
The landing occurs near the end at 1:33.
There a couple of concepts at play here. One is that if it takes 90% of your initial mass to propel your rocket to top speed, it will take 90% of the remaining mass to decelerate it to zero. But since you only have 10% of your mass left after reaching your target speed, you only need 9% of your original mass to decelerate.
Since we are talking about boosters, we are disregarding the payload and a bunch of other stuff. The point is that after the booster has done its work by getting the payload on its way, it has used most of its fuel, and after dropping the payload, it is much like an empty beer can, it has relatively little mass and so is going to need very little fuel to return to the launch pad.
However, it is going to need some fuel, because it has a bunch of contortions to go through. First, when it drops off the payload it is going at near orbital speeds, on the order of miles per second, so it has to slow down. It has to slow down to zero before it can begin flying back to base. As its speed drops, gravity takes a bigger role. When its speed is zero it is like a big rock (or a big empty beer can) falling out of the sky. Now it needs to accelerate back towards the launch pad, which might be 100 miles away, but don't go too fast, because halfway back it will need to turn around and start decelerating for the landing. Speed up, turn around, slow down, speed up, turn around, slow down, and do this all while maintaining a heading that will keep you off of the ground and slow enough that you don't burn up in the atmosphere.
The Curse of Stuff
Self-storage lockers are the fastest growing business in the USA, at least according to the Internet. I can believe it. While we were raising our kids we were in heavy accumulation mode. You need stuff, so you buy it. But when you're done with it, if it hasn't been destroyed, you save it. I mean you paid good money for it, and maybe we'll need it again someday. Save it! It's valuable!
We are pretty settled in our ways now and most of that stuff is not going to be needed, we should get rid of it. But what if we do end up needing it? Buy a new one. The aggravation you save by not having to inventory a zillion things you probably will never need outweighs the tiny spark of joy you get when you realize that you need that widget you saved from 1909.
Goodwill is the obvious choice for some things, but not all. Things like tools. They are of interest to only a small proportion of the population, partly because firstly, only about 10% of the people have any aptitude for fixing things, and secondly because most modern devices cannot be fixed and should just be thrown away when they break.
I've been thinking I should put some ads on Craigslist to see if I can get rid of some of this stuff, but it's a hassle. It takes, time, you have to fill out forms, you have to be at least semi-organized, and you have to stick with it. It's a whole lot like work. My wife and I finally got together and started on this project. We've been at it for a couple of weeks and we've had some success. We've sold a couple of items and given away a couple of things and the relief we got from having them gone is palpable.
The hard part is setting prices. If you paid $500 for something that is still functional and useful (i.e. not obsolete), you don't want to let it go for $20. You're disrespecting the item, whatever it is. But you are unlikely to get $250 for it either, unless it's a musical instrument. There are two factors at play here. One is how much you want to get rid of it, and two is how long you are willing to wait. There are people out there who are religiously scanning the ads for bargains on stuff they can turn around and resell for a profit. But if you have some oddball stuff, it may be a few weeks before someone who can use it will bother to check the ads and give you a call.
I had a box of baseballs I was giving away. Took two weeks before anyone called. A $200 gas barbecue grill got no calls when it was priced at $100. At $50 it was gone in a week.

Tunes
These two tunes popped up on YouTube this evening. They have the same title, but, to me, they don't sound anything alike.
Dino Dvornik - Jače, manijače (1990)
Zemlja gruva! feat. Gidra - Jače manijače
This singing of this tune (done by Gidra) got my attention, enough that I interrupted my solitaire game to find out just what it was. It was only then I discovered it contained a couple of bits of talking (rapping?), which turned me off. But Gidra is pretty great. I'm not sure what language they're using. Russian, Hungarian, Serbian?

Crossing the Bitterroot Mountains
Getting around the Bitterroot Mountains
Jack & Randy have gone on an expedition to explore some old roads that cross the Continental Divide which happens to form part of the border between Idaho and Montana. The northern road (on the map) is the Lolo Motorway:
In the northern part of the state a famous travel corridor winds through the forests of the Bitterroot Mountains. It’s most well known as part of the route followed by the Lewis and Clark Expedition. But the Corps of Discovery was actually following the well established northern trail of the Nez Perce Indians. It was used by them for centuries to travel east into buffalo country in what is now Montana. In the early twentieth century a rough dirt road built by the Civilian Conservation Corps traced a good portion of the original Nez Perce Trail. That road is now known as the Lolo Motorway.The southern one is the Magruder Road (pdf).
The 101-mile primitive Magruder Corridor Road winds through a vast undeveloped area, offering solitude and pristine beauty as well as expansive mountain views. The landscape is much the same as when the Nez Perce Indians and other early travelers crossed the area. The road has changed little since its construction by the Civilian Conservation Corps (CCC) in the 1930s. It has also been known as the Southern Nez Perce Trail, Elk City to Darby Road, Montana Road and the Parker Trail.I have taken I-90 across northern Idaho a few times. It follows the St. Regis River, mostly.
The yellow icon marks the Moose Creek Airstrip. Marc flew over there a couple of weeks ago in his new-to-him Piper Comanche. The Comanche is turbocharged, which means he can get up to 15,000 feet. On the way there, at that altitude, he picked up a tailwind which meant it only took him a couple of hours to get there. His co-conspirators in smaller, 100 MPH airplanes took almost 7 hours to get there.

Tuesday
I just stopped in the TV room to see that my wife was watching American Idol. They were just introducing a choir from Los Angeles so I stayed to watch. When the song was done and the judges started yapping, I left. This is pretty standard for me. I don't watch the news or weather or sports shows, any show that is mostly talking. It just occurred to me that I do this because listening to any broadcast of people talking is a waste of time. The amount of information contained in a broadcast would fit on a sheet of paper that could be read in couple of minutes. I don't need to spend the next hour listening to these guys jabber, especially since it's a one way street. They aren't listening to me, so they don't deserve any ear time from me. This might be why I don't like long conversations on the phone. If you've got something to say, i.e. some information to impart, spit it out. We don't need to spend the next a couple of minutes chatting about whatever. I do enjoy talking to people face to face, at least some people, some times. I can only do that for an hour or two at most. After that I need a break.
We have come so far in large part because of our ability to devise solutions to large problems by finding small operations, easily repeated, that when endless repeated solve the problem. Hand woven Turkish carpets come to mind, as does dropping seeds in a furrow, one by one. Building the pyramids was essentially two operations: cutting blocks of stone, and hauling them up a ramp, and doing it over and over again. The modern assembly line consists of a zillion trivial operations performed in sequence. Each operation consists on doing one thing and then handing the part to the next operator. The printing press and broadcast radio and television repeat the same simple messages over and over. Much of computer programming consists of devising ways to do some simple thing over and over again.
Elon Musk, aka SpaceX, got a contract a while back to delivery a dozen cargo capsules to the ISS (International Space Station). The contract was for $1.6 billion, which means NASA was paying $100 million per supply delivery. $100 million dollars is a large quantity of money. With that much money you could hire a thousand people for a year, which is essentially what happened. While some outfits may be making a bundle off of these contracts, I suspect many of them have invested serious money in developing the capabilities needed to actually deliver the goods. We won't count the initial investment in time because these guys were doing what they loved. I mean, why else would you build a rocket unless you loved it? I mean they aren't really good for anything. We've got all the rocket power we need to put satellites in orbit, if you consider satellites useful. I'm not entirely convinced. The only reason they're doing this is because they want to learn how to build bigger and better rockets, rockets that will take us "to infinity and beyond!"

Make America GR8 Again
A VERY STABLE GENIUS - Randy Rainbow Song Parody
I really enjoyed the clever word play in this video.
I'm beginning to think (becoming convinced) that politics is just a show to keep us entertained. I don't know whether Trump is doing any good or not. National policy is above my pay-grade, and besides, I disagree with just about everything the National government does, and I always have. This isn't a new attitude I acquired with Trump, I felt the same way about Obama and every president back to JFK. I liked JFK, he used T-Birds in his inauguration parade. But you saw what happened to him.

Nick U
My daughter doesn't like math. She got through college, and now is almost through nursing school, so she can do what's needed, but she doesn't like it. She's been working / training in the Neonatal ICU (the NIC-U) recently. Tonight we went to dinner at Amelia's where she gave me a rundown on one example of how math impacts her job.
Premature babies have a (some kind of special) PICC line through which various fluids are fed. The line is twinax - i.e. it has two parallel tubes. Each line has three different substances being fed into it. There are basics like salt and sugar, but there are also hormones and fats and I don't know what else. Most of these are fed in a low volume, continuous stream, but sometimes they need a medicine of some sort. In these cases, when the medication is 'compatible' with the stream, it can just be added directly. If the medication is not compatible, the stream has to be interrupted, the line has to be purged, the medication streamed in, and then the original stream is reconnected. What makes it more complicated is that not everything is fed at the same rate. Your normal feed stream might be one milliliter every five minutes. The medication feed rate might be same or higher, or it might be as little as one tenth of a milliliter in an hour. And don't forget that the line itself has a capacity of eight tenths of a milliliter, so how long do you need to run straight saline solution in order to flush the line? And don't make any mistakes, a small person's life is depending on your getting it right.

The Hitman's Bodyguard
The Hitman's Bodyguard Red Band Trailer #1 (2017) Ryan Reynolds, Samuel L. Jackson Action Movie HD
Very silly, action packed, silly love story. Samuel L. Jackson cursing loudly the whole time. Lots of stunts, an endless supply of bad guys meeting their doom at the hands of our heroes. One chase involved bad guys in cars chasing a speed boat through the canals of Amsterdam. That was interesting, haven't seen too many movies set in Amsterdam.
The villain is the dictator of Belarus. He is portrayed as being an evil man, like many East European dictators. Belarus seems to have some problems, but it doesn't seem as bad as some places.

Electric Steam Rocket
The Parker Solar Probe is going
to visit the sun. News reports make it sound like
they are going right up to the sun, but they are only expecting
temperatures of 2500 degrees which doesn't sound that hot since everyone
knows the sun is a zillion degree, so something is off here. Then I
find that they are only going to within 8 million miles (or is it 8
diameters) of the sun. Well come on, guys, that's not really touching
the sun is it? I mean 50 years ago Ray Bradbury had guys in a space ship flying right up to the sun collecting some of the sun's super-sized atoms using a super hi-tech / magical ladle.
It's still closer than anyone has managed before. It's going to take them 7 years to get to the sun, which is only 8 light minutes away. Which got me to thinking that we need a faster rocket.
One idea that's been kicked around in hard science fiction is the fusion rocket, a rocket uses the energy released by fusion to heat and expel some kind of magic propellant. The first version is probably going to use water as the propellant, with a touch of helium. In other words it's a hi-tech steam engine.
Forbes has a story about hydrogen fusion projects in the Pacific Northwest, which is very cool. So I'm reading about all the different techniques various groups are using to try and get hydrogen atoms to fuse . . . and I'm left wondering how are they going to harness all this power if they ever do get it work? And then someone mentions heat. Heat, which is what we use coal and natural gas and uranium for. Heat that is used to heat water to make steam. Steam which is used to drive turbines that turn generators that generate electricity.
So the first step, if or when they actual get hydrogen fusion to work, would be to replace all the fuel fired boilers and nuclear reactors which fusion powered steam generators.
Is that all we can do with hydrogen fusion? Boil water? That seems, so, I dunno, archaic? Or maybe Rube Goldberg? Seems there ought to a better way to do it. I'm sure we will eventually find a better way, but right now that's all we've got, so let's see what we can do.
Another idea (my idea, I haven't seen it anywhere else, which doesn't mean much) is to use a linear accelerator to accelerate tiny sand grain sized particles of iron to some fraction of the speed of light. To create magnetic pulses powerful enough to propel our grains of sand to relativistic speeds, we are going to need some serious electrical power. And where are we going to get that power? From steam turbines powered by hydrogen fusion!
We're going to the planets with a steam engine!

Secret City
Secret City - Trailer season 1
Short (6 episodes) series about modern day espionage in Australia. The arch villain reminds me of Hillary Clinton. That's not a coincidence, is it?
Everyone is chasing a SIM card from a smart phone. Supposedly it's contains a secret that someone is willing to kill to protect. The government security outfits (an alphabet soup of acronyms, much like what we have here in the USA) is very interested in this tiny little computer part.
One government agency has a TSA like security protocol for anyone coming into the building. They even have cell phone lockers for employees where employees can leave their smart phones when they come into the building. But the employees use computers inside the building that are connected to the outside world. How secure is that? It could be very secure if the people who are in charge of computer security know what they are doing, but if they are using any kind of commercial software there are going to be holes.
Problem is the way modern computers use RAM (random access memory). Any computer program is composed of two parts: code and data. The code is the program (the sequence of instructions) that the CPU (central processing unit) executes, and the data is what those instructions operate on. Both code and data reside in RAM and while there are flags that can be set that will tell you whether a particular block of RAM contains code or data, those flags can be changed, so what was once data can now become code and vice versa.
You can test your code all you want, verify that it has no holes and will not let anyone do anything that would allow the release of confidential information, but if you allow a program to change that flag on a block of data (which undoubtedly came from outside), you will now have a wild program running loose in your system.
Modern commercial computer software does this all the time. Javascript, which is what every web app (application program) in the world uses, comes down the pipe as data and is fed to the Javascript engine which interprets the Javascript instructions and executes bits of code as instructed. Now the Javascript engine may be very secure, but unless someone you trust has gone through it and verified that it cannot possibly do anything bad, how do you know? And is it even possible to verify it? I suppose, if you have set up some hard and fast boundary conditions, it might be.
Java, on the other hand, is not allowed on Chromebooks because it cannot be contained. You could make a Java interpreter that was constrained, but that is another software project that would need to be tested, vetted and verified.
I'm thinking if you want a secure computer system, you would need to write the code yourself, which means you are going to need an army of programmers. Big government agencies can afford that, but there are not too many people who are creative enough to write code and are docile enough to work with the restrictions imposed by working for a big Federal agency. Plus, programmers are people too, so some of them are liable to take short cuts, like 'borrowing' code from outside. And there might be a point where your system becomes so complex it is not possible to know whether every component has been rigorously tested and is known to be secure.
All it takes is one little loophole known to one guy and the whole thing can be compromised.

Hillsboro Hops Baseball
Ron Tonkin Field |
This place started with a football / soccer stadium. I think it was for high school teams that didn't have their own, I dunno, but a couple of years later they built the baseball stadium in back of it. The lower roof on the left side of the picture covers the baseball seats. The four towers at the top support the roof over the football stands which back up against the baseball stands. The place is wire rope heaven. The roofs of both stadiums supported by cables, there are nets in front of the stands made of wire rope and the nets are supported by more cables.
Theoretically, baseball is a simple game, and it seems to move slowly, but you can mosey along until you have a precarious position and then something will happen to trigger an avalanche of activity. You have to be paying attention to catch it all, and even then you might not.
The only bad thing is getting out of the parking lot. We left after the 8th inning so it wasn't too bad. I would have liked to stay for the whole game, but needs be. I don't know how long it takes the parking lot to clear out. Maybe long enough to drink a beer in the bar, if they are still open.

The Skin of the Wolf
THE SKIN OF THE WOLF by Samu Fuentes - TRAILER
Ever wonder what a solitary, primitive life would be like for a man living in an abandoned mountain village? This film lays in out in excruciating detail. Two women get inserted into the story, but I don't think there two dozen words spoken in the whole film. Some people don't need a great deal of conversation. Hollywood Reporter has a review. I don't agree with many of the suppositions. It could very well be a current event, although you would have to work pretty hard to avoid everything from the 20th century.

I've been listening to Munros Retro because he has hit songs I like AND dancing girls, which is always a good thing. No dancing girls in this one, or not that I noticed. I haven't heard this song in a coon's age. I recognized it right off but I didn't know it was done by Procol Harem. The only song I know of theirs is Whiter Shade of Pale, which is a fine tune I suppose, but I've heard it enough times I don't need to hear it again. But this one is still pretty cool, meaning I'm not burned out on it yet.

The Diamond Age
The Diamond Age (as in The Bronze Age or The Iron Age) might have not quite arrived, but it's getting closer. We now have a couple of different methods for making synthetic diamonds and they work well enough that they are economically viable, i.e. they can make gemstone size diamonds and are undercutting the natural diamond producers like DeBeers.
I remember hearing about some guys trying to make diamonds a while back. They were having some success using washing-machine size machines that focused enormous pressure on a tiny little sample. That was ten years ago or so.
The Diamond Age is also the title of a science fiction novel by Neal Stephenson. One of the premises of that story is that man has learned to make diamonds and it has opened whole new venues of technological progress. Society as a whole still sucks, but what else is new?
I'm not sure how I got started on this, but when I started looking I wasn't finding much, well, except for a bunch of ads for engagement rings. But eventually I found some bits and pieces. Here are some videos give a pretty good overview of what's been going on.

I also remember watching a video where a guy made diamond from pencil lead using a microwave oven, but I can't find it now, so maybe I just imagined it. If so, I've got a really good imagination because I remember it clearly. In any case he turned a ceramic coffee mug upside down and used the depression in the bottom as a crucible. He laid a couple of leads from a mechanical pencil there and added a couple of drops of oil (mineral? vegetable? my memory is fuzzy on this point). He set another coffee mug on top, this one right side up, so the graphite and oil are semi-contained, and then he fired up the microwave and ran it for I don't know how long. I don't recall what method he used to verify that his experiment worked, but if it did, the crystals were very small. Really bugs me that I cannot find this video.
The older HPHT (high pressure, high temperature) method is still in use and has grown considerably:
And grown some more:
China is producing quantities of gemstone quality synthetic diamonds and shipping them to India where they are cut and made into jewelry.
Considerable effort has also been expended in finding ways to determine whether a diamond is synthetic or natural. One way was to laser engrave some kind of a miniature marking on the edge. Another uses spectroscopy. Natural diamonds usually include a bit of nitrogen and synthetic diamonds don't.
I remember hearing about some guys trying to make diamonds a while back. They were having some success using washing-machine size machines that focused enormous pressure on a tiny little sample. That was ten years ago or so.
The Diamond Age is also the title of a science fiction novel by Neal Stephenson. One of the premises of that story is that man has learned to make diamonds and it has opened whole new venues of technological progress. Society as a whole still sucks, but what else is new?
I'm not sure how I got started on this, but when I started looking I wasn't finding much, well, except for a bunch of ads for engagement rings. But eventually I found some bits and pieces. Here are some videos give a pretty good overview of what's been going on.

Linear Accelerator
How a Linear Accelerator Works - HD
Looking for images of linear accelerators, I stumbled over this video. First time I have seen a linear accelerator used for any practical application, and the first time I have seen one this small. Usually I expect to them to be big machines buried in some obscure basement of a university physics department building. They are certainly going to a lot of trouble to produce X-rays, but I imagine there are reasons for that, like higher power and more control.
The whole thing about using radiation for cancer treatment is that the mutant cells, which is what cancer cells are, are not so good at repairing any damage they incur, so a good dose of radiation will damage them enough so they will die. Healthy cells can repair a small amount of radiation damage, so the trick is to administer enough radiation that the tumor is damaged enough to kill it, but healthy tissue is able to recover.

GLOW
GLOW Official Trailer (2017) Alison Brie Netflix New TV Series HD
We watched the first three episodes this evening and it's very funny. Also absurd. There are some awkward moments, but I suspect sometimes you need those to set up the punch line, if that's what you call the point in the action where it hits you.
It also gives you a little insight into what it's like trying to put together a show that might see the light of day: a whole lot of schmoozing with people who have a radically different world view than your own. People who can do that, and are lucky, might make some money, and from where I sit, they are fully entitled to it. I never had the patience to deal with most people.
And remember the untold zillions who showed up for the casting call and were turned down. I don't quite understand the drive to be an actor. I mean you hear about people doing any kind of menial work, like, god forbid, waitressing, in order to survive long enough that they can go to another casting call. Or maybe it's just that there are so few acting jobs that even if one one hundredth of one percent wanted to be an actor, it means that a thousand people will show up for any job that shows any promise at all, so with that kind of competition, only the most driven, or lucky, will survive.
On the other hand, maybe we're lucky there are so few acting roles. It might create a shortage of waitresses and that would be very bad on account of I like to go out to eat. I think now I might be able to wait tables. I never considered it when I was younger. Can't quite explain why. Probably because I started developing a gearhead mentality and I lost interest in dealing with people. So let's hear it for all those people who work in restaurants, the cooks, waiters / waitresses, busboys, dishwashers, hosts and, yes, even the managers. Hip hip hurray! I appreciate what you are doing!

PillPack
PillPack dispenser and packets |
Did I actually think of it first? Doubtful, I am sure many people have had the same thought over the years. If I wanted something to boast about, I could imagine that my blog post was the trigger that somehow got the ball rolling.
It's kind of hard to imagine that such a numb-skull idea could be worth so much money, but then lots of people are taking lots of pills, and the value of a business is pretty much defined by numbers. Multiply a zillion people taking zillions of pills times the pennies they will charge for each dose, and then multiply that by some zombie number that converts present revenue into future value and, well, somebody decided it was actually worth a zillion dollars.

DEW Line
Watching for Nuclear Attack at the Top of the World
The DEW Line has always been around, at least in my lifetime. I had always heard about it, but I never got an idea of the scale, probably because it was classified, or somebody decided that no one was interested. This is the second time I've posted one of Tom Scott's videos (first time here). He doesn't dig very deep, but he does give a good overview of WTF has been going on in some very obscure places.

Charles Bronson Lives!
10 Badass People Who Used Helicopters To ESCAPE
Saw this headline French robber Redoine Faid breaks free from jail in dramatic helicopter escape and immediately thought of the Charles Bronson movie Breakout where he helps a guy escape from a Mexican prison. I thought it was just an adolescent fantasy, but evidently several people have managed to actually pull it off.
