Dunkirk


Dunkirk - Trailer 1 [HD]

I wasn't impressed, though maybe it's hard to make a compelling story out of a disaster. The story follows a small group of soldiers as they get on board one doomed boat after another. The only indications we have that the evacuation was a massive effort was Wallander spouting some numbers and the occasional panoramic view of endless queues of soldiers standing on the beach waiting for boats to come take them back to England.

Some of the stuff struck me as contrived, like the Spitfire pilot who can't get his canopy open after he has ditched his fighter in the English Channel and it is rapidly filling with water. And then there was the scene where a destroyer loaded with troops gets bombed and starts sinking and nobody inside the common room can open the door to the outside, once again while the water level is rising. A guy on the outside has to open it. Yes, these things could have happened, but they really don't do anything for the story. They just serve keep you on the edge of your seat, and they don't do that very well because you get that feeling that you've been set up and someone will come along and rescue them.

MJ Hegar - Doors

I like this video. I don't know MJ Hegar, and I don't live in Texas anymore, but I really like her can-do attitude, so unlike all the whiny bullshit you get from the mass media. Plus she has the door from her chopper on her dining room wall. That is too cool.

Round Rock is just to the North of Austin.

Atomic Blonde


Atomic Blonde Red Band Trailer #1 (2017) Charlize Theron Action Movie HD

Charlize Theron does James Bond, or maybe John Wick. It's not a very good movie, it's stylish (I mean we do have Charlize) and it's action packed, but it's a little confused, or maybe that's just me.

The best part was the soundtrack. The film is set in November 1989 in Berlin while the wall is coming down. They pull all these lines out of these hit songs that make you wonder whether the songwriters knew what they were talking about, or maybe they were just channeling society's turmoil.

I found one playlist on YouTube that has most of the tunes from the soundtrack except for this one, which I have been listening to lately.

Broken Wrist

Acu-Loc Wrist Repair Plate
My wife tripped over a kindergärtner and fell down a couple of weeks ago and broke her wrist. It looked like she might be able to get away with just having a cast until we went to see the bone doctor. Now surgery to install a small plate to hold the bones in alignment becomes a viable option. The two advantages to having surgery were that she could get by with a smaller cast because the plate would be doing most of the alignment work, and there was a possibility that without the plate she would encounter some pain when she turned her wrist. If she was 20 years older, they wouldn't recommend the surgery. So we went ahead and got it done. Picked her up from work at 2PM and were home by 9PM. Work was done at the clinic, not the hospital. The worst part was they used a nerve block on her arm which meant is was virtually dead for 24 hours. There was no pain, but she was also unable to control her arm. Left alone it would just hang by her side.

A little info about wrist fractures:
A Colles' fracture -- or distal radius fracture -- is often called a ''broken wrist.'' Technically, it's a break in the larger of the two bones in your forearm. The bone breaks on the lower end, close to where it connects to the bones of the hand on the thumb side of the wrist.
Colles' fractures are very common; they're the most frequently broken bone in the arm. In the United States, one out of every 10 broken bones is a broken wrist. - WebMD

CO2 & U


Disney '43 - The Winged Scourge

Talking to a guy I know, he tells me he was plagued by mosquitoes last January, here, in Oregon. Seemed a little far fetched, but winters are pretty mild here, and he insisted, sokay, fine, mosquitoes in January. He showed the county bug man a sample and bug man, said, yup, that's a mosquito. He actually went into some scientific detail about it. Seems there are 40 or 50 different species of mosquitoes living in Oregon. They set up some mosquito traps around the house. Mosquitoes travel in straight lines out from their breeding grounds. They checked on the traps a few days later and the traps showed a definite direction for the source of the mosquitoes. They did some searching and quickly located a covered swimming pool that hadn't been adequate poisoned (chlorinated). Cleaning that up eliminated the mosquito problem.

I'm watching another video about how they control mosquitoes at Disney World and I notice that they are using a whole bunch of animated clips. A search on YouTube turned up the above video. The mosquito traps they use at Disney World give off CO2, which seems to be a mosquito attractor. Don't want to be bothered by mosquitos? Quit breathing.

Nitrogren Atmosphere Warning Sign

Or not. When you are holding your breath, it is the increasing level of CO2 that makes you desperate to breath, not the loss of oxygen. As such you can suffocate a person with nitrogen. They aren't getting any oxygen, but their CO2 concentration is not increasing, so they have no sense of being desperate. If you don't get any oxygen you will just pass out and die. It works so well that some states may start using it for executions instead of lethal injection. Some produce warehouses employ a nitrogen atmosphere to help keep produce fresh. Don't be walking in there to get you some veggies, well, not unless you are looking to become fertilizer.

Paris Green, mentioned in the Disney video at top, is a poison. It is made from copper(II) acetate and arsenic trioxide. Didn't I just run into arsenic trioxide? Yes, I did:


Freezing 200,000 Tons of Lethal Arsenic Dust

This is the Giant Mine at the Great Slave Lake in Northwest Territories in Canada. Makes me wonder how many people died of arsenic poisoning at this mine when it was in operation, or, if nobody died, how did they manage to keep people from being poisoned?

"Teardrop" - Massive Attack


"Teardrop" - Massive Attack

I used to listen to this tune all-the-time but after nine zillion plays it became firmly embedded in my brain and I started listening to other stuff. Just stumbled over a thread on Reddit full of comments from other people who also like it. Might have to spend more time on Reddit.

Reddit has redesigned their website and I don't like the new format so I use the old style.

Ogallala Aquifer

Ogallala Aquifer
The Ogalla Aquifier provides most of the water used for crop irrigation in the High Plains of the Central United States. There is some question as to how long it will be able to continue doing so as farmers are sucking it up at a rate of two feet a year. I suppose it depends on how deep this pool of water is. If it's 1,000 feet deep, then that should be enough water for 500 years. If it's only ten feet deep we'll have giant dustbowl later next week.

American Made


American Made - Official Trailer [HD]

The story of Barry Seal has been kicking around in the fringes of polite society for a long time. It's good that it's finally seeing the light of day. As a movie, it's great, lots of action, lots of crazy. The only problem is there is just so much crazy crammed into it. Was the CIA really doing all that shit? It kind of looks like they were. When you live in Disneyland it's easy to forget that just outside the park, crazy is the norm and chaos is the order of the day.

Emotion

When I get tired I get cranky, and I must have been tired today because I sure was cranky. Doing the laundry, the washing machine seems like it's done, there's no water flowing and it's not spinning, let's open it up and get the laundry out, but we can't, the door is still locked. The fancy little digital display says it still has two minutes to run. WTF is it doing? It's turning the drum slowly. Why? Stupid machine. If I hadn't happened to walk in there at just that moment it wouldn't have been a problem, but I did, and I'm tired, so WTF are you doing you stupid machine? It finally finishes and beeps, so I open the door. Then the accursed POS beeps at me again. What kind of ignorant savages programmed this thing? Someone should cram one of these beepers in their ear.

I go to McDonald's to pick up a couple of sandwiches for dinner. It's dinner time and the drive up queue is full. This McDonald's is fancy, they have two (2!) speaker boxes for taking orders. I have been here before when they were operating smoothly and they will take orders at both boxes and never seem to get confused. Today is not one of those days. I pull up to the speaker box and it tells me to order at the next speaker box. Okay fine, not a problem. But then it tells me again. FU, you annoying POS, I heard you the first time.

Eventually I get to the goody window, but instead of handing me my bag of goodies, the large woman asks me to pull around front and park and they'll bring my order out to me. Well, sheet, but okay, that's what I get for ordering something with 'artisan' in the name. It's okay for five minutes, but when we get to ten I've had enough and stomp inside to find out what's going on. The small woman in charge tells me they are waiting for the chicken to come up. whatever the $%^ that means. Screw that, gimme my money back, which she does. I go to Wendy's and buy hamburgers. If they had warned me that it was going to take an hour when I ordered, that would have been one thing, but they didn't.

Some emotions are easy to identify. Cranky, cheerful, content, happy are pretty obvious. But stress can distort your emotional state without making itself known. My wife broke her wrist last week when she tripped over a stationary kindergärtner and fell. It didn't seem too bad. She went to the ER where they took some X-rays and and wrapped her arm up with a temporary cast. But then we go see the bone doctor and now it looks like surgery might be in order. It's not a big deal, they make two inch long incision, line up the broken bit of bone, slip in a little metal splint, screw it down and sew up the incision. Surgery was Thursday afternoon. I didn't sleep well Wednesday night, I got maybe a couple of hours. Surgery went well and last night I slept pretty well. Today I am still very tired and as a result I find even the littlest things immensely irritating, as you may have noticed.

Subaru

Uniberp got me started with his post about replacing the valve cover gaskets on his Subaru. This video gives you pretty good idea of the pain involved. It's a little long but he doesn't waste any of your time.


How To Subaru Valve Cover Gasket Replacement part 1

Uniberp needed a wrench to get the job done:
1/4" sliding t-handle
I need one of these to get a valve cover bolt off, in a very tight position. Seems I should have one somewhere but no.

Sears has one, $8.48 plus shipping

Grainger has one, $134.50

Nope at Ace or NAPA or Advance Auto

I will check Harbor Freight on the way home

Grainger probably has to order it anyhow.

Success. I found a 1/4 breaker bar $9, by Crescent, at Menards. Drilled a relief hole sideways into the aluminum threaded boss to relieve the stuck pig bolt before it twisted off and I would have had to remove the engine which would have been necessary because it would have leaked oil like a sieve.

Yes this preventative maintenance needed to be done. There are seals around the spark plug holes that harden and leak and fill the spark plug tube with oil.
I'm impressed with Grainger's price. I suppose having a supply chain that can deliver whatever you need has its benefits, but I am still surprised by the premium they charge.


1969 Subaru FF-1 station wagon


A long time ago I had a Subaru. I think it was a '69 model, give or take a year or two. It had 80 HP and got 30 MPG. Gas only cost a quarter, but minimum wage was only $2.25. If memory serves, the car cost $1400 used. I got my parents to buy it for me on the premise that I wasn't never going to college. I suffered through high school and I was thoroughly sick of school. I drove the shit out of that car, from Ohio to Florida, California, up and down the West Coast, back to Ohio and eventually to Texas where, after being crunched twice and two major engine repairs, I sold it for parts. It was a little tin box, but it went fast enough to keep up on the freeway.

Subaru's are very popular here in Oregon. They are especially handy if you go to, or over, the mountains in the winter time. I don't like them because I suspect the viscous coupling they use to connect the front and rear drive axles is some kind of Japanese bullshit, i.e. a very expensive component that you can't repair yourself. If it fails the least you can expect is you'll have to buy a new one from the dealer for half the price of a new car. Of course if it never fails, it's not a problem. I have no evidence to support any of this, just my feelings on the subject. I suspect that the only cars that use this technology are Subaru and  some overpriced German snobmobiles, and being as Chuck rhymes with Cheap, I ain't spending any money on these kind of gimcracks.

If anyone who spends considerable time driving on snow covered roads asked me what kind of car to buy I would recommend Subaru without hesitation. The odds of having to make an expensive repair are so low that it doesn't merit consideration. But emotions are not logical. The pain of having to fight for traction on snow covered roads is something you will carry with you long after you have forgotten how much you paid for anything as mundane as a car repair.

A friend of a friend makes a little extra money during the summer by buying Subarus in Florida and driving them to Oregon, which strikes me as pretty weird, but then we did score a deal on my daughter's Mazda in Florida. That was the one bright spot in our ill-fated adventure to Miami.

Wallander


Emily Barker - Nostalgia (Wallander version)


Just finished watching the last episode of Wallander on Netflix. We watched the whole series over the last month. The first three seasons were pretty much standard murder mysteries, but the last season took a left turn off into the boonies. The last episode (S4:E3) with the CIA and the cold war was just nuts. There were a couple of lines in there that just sent me over the edge.

Synopsis: Hakan, an aged, retired, Swedish submarine commander, has disappeared and his wife has died, an apparent suicide.
1:11:00 Kurt Wallander and Steven Wilson, an American, probably CIA. Kurt walks in the front door of Hakan's house carrying something wrapped in a tarp.
CIA: Hello, Kurt.
CIA sits down, Kurt pours and brings him a drink.
Kurt: There you are.
CIA: Ah, that's mighty kind of you.CIA: To your health.K: So what are you doing here?
CIA: (SIGHS) I guess I didn't make my flight. . . . I've been trying to think of some piece of information that might help figure out what's happened.
Kurt: And did you think of something?
CIA: A friend of mine and I, we were colleagues . . . And I had this deal with him that he would help me. And if ever he became troubled by any consequences, then he would let me know and I would help him, in return. And the way that he would let know would be that he would disappear.
Kurt: And how would you help him?
CIA: I'd find him, take him elsewhere.
Kurt: (opens tarp) It's an American device. Those submarines weren't Russian, they were American, and Hakan was working for you.
CIA: (nods) At that time, it was considered a priority to destabilise the government here. It was perceived as being Communist. It worked. After the fake Russian subs, support for the East dwindled away to almost nothing. Which was another border made safe, another front closed down.
Kurt: And Louise? Louise? So, was it always part of the rescue plan that she would die? That he would arrange a suicide, leave evidence to blame her?
CIA: I liked Louise.
Kurt: Where is he?
CIA: Waiting for me. But I won't go fetch him. It would be inadvisable for us to become involved. Far better for someone else. Someone with an interest to make him face up to his responsibilities. To what he's done.
Kurt: What about your responsibilities? You wouldn't be here if you weren't afraid to face them. If I confront Hakan with what he's done, I'll make sure I do the same for you.
CIA: You're not in the best of health. You have a family. Are you sure you want to make that threat?
Kurt: Where is he?

There was an incident involving a Soviet sub in Swedish waters back in 1981, but it was definitely Soviet. There have been a number of other incidents that were blamed on the Soviets, and given the one big red flag, they probably were triggered by Soviet subs, not American ones. Some people disagree. But you know, conspiracy theories don't need any facts, and blaming the CIA is a popular sport, so let's blame them. Google has more.


Bugs

I've been working on my Farey addition program and I found a couple of bugs. The first one a simple mistake that took me four days to find, mostly because my mind was a bit fuzzy. The problem was that I was using abs (absolute value function for integers) instead of fabs, which is the same function, but for floating point numbers. One little letter and everything is wrong.

Got that corrected and now I'm running the program and when the denominator gets to 4142 it goes off the rails. What the heck could be causing that? It's been working fine for the first 4141 denominators, why should it choke on 4142? It blows up when it is checking the Farey addition. Doing this only involves integer operations, and they are all relatively small integers, we aren't going to overflow the accumulator. What could possibly be go wrong? This one had me stymied for a couple of days, I couldn't even think of what to look at. There is nothing wrong except it doesn't work.

This morning my brain served up a clue. When I generate the fractions, I compute their decimal value and use that to sort my list of fractions. The problem is that I also depend on this value being unique. If two fractions have the same decimal value, I presume they are duplicates and eliminate one. The problem might be (I haven't verified it yet) is that two fractions could have the same decimal value, but be different. For instance, Google delivers these values:
2048 / 4007 = 0.51110556526
2071 / 4052 = 0.51110562685
2117 / 4142 = 0.51110574601
The first 6 digits of these three fractions are all the same. After that they diverge. In my debug output, they all show the same value, but then I am only printing the first six digits. Standard floating point values hold much more than six digits, so maybe there is something else going on here. Anyway, I've got a place to start looking which is more than I had a couple of days ago.

Fly Me To The Moon


Black Hawks and Osprey Aircraft Create "Kopp-Etchells Effect" During Low Light Exercise

The bright halo of light emanating from the tips of the helicopter's rotor blades is caused by sand particles impacting the leading edge of the rotor blades. This constant abrasion erodes the blades  making them unusable in short order. To combat this, the leading edges of the blades are now reinforced with a tough material like nickel or titanium.

The impact knocks loose a tiny chunk of metal as well as heating it. It might it heat it to incandescence and we are seeing the metal particles glowing, or it might heat it to the point of ignition and we are seeing the particles burning. Or it might be a little of both.

Around the 1:20 mark (in the above video), we see a couple Osprey fly over, and you can see a soft glow from the tips of the rotor blades. This is likely from the glow-sticks the Army has attached to the rotor blades, not the Kopp-Etchells effect.

Re the name:
The combat photographer and journalist Michael Yon observed the effect while accompanying U.S. soldiers in Afghanistan. When he discovered that the effect had no name he coined the name "Kopp-Etchells Effect" after two soldiers who had died in the war, one American and one British. - Wikipedia
Michael Yon has some photographs.

Another rotor craft heading up. How high does that thing go? It looks like it's going to the moon! It is not actually a rotorcraft. It spins around, but the only thing giving it lift are the rockets.

A Girandola is an outgrowth of the Catherine Wheel, named after Saint Catherine who was to be executed on a breaking wheel, but said wheel shattered at her touch.

Flying Girandolas, like this one, have been around since the 19th Century. If anyone built one earlier, they're keeping mum.

Similar effect to what we saw with sand hitting the helicopter rotor blades, but no oxygen on the moon means we are only seeing incandescence, not combustion.

Portland Parking Meter
Most of the city parking meters I have used recently print a ticket for you that needs to be displayed in your car. This one dispenses with the dispensing. You enter your license plate number and pray that you entered it correctly and the meter man interprets it correctly. It all works fine except that the screen is hard to read, especially the labels displayed above the yellow buttons because some punk jackass had to carve some kind of bullshit into the screen. I would say it looked like Asian gang characters, but that's probably racist, and it could have been Klingon for all I know.

Tangent Circles

Fun with Circles
I came across this bit of geometry on Quora the other day. I haven't quite sorted out just why it works, but if it does, it's pretty cool. I was so impressed with it that I printed a copy and took it lunch to show the gang.


Funny Fractions and Ford Circles - Numberphile

Dennis responds with this video, which also has a bunch of tangent circles along with some goofball math. I saw this and thought that it wouldn't be too much trouble to write a program to verify what's going on here, so I did. Turns out there were a couple of tricky bits that needed sorting, but I think I have it. The first tricky bit was figuring out how much memory I would need. I wrote about this a couple of days ago.

int gcf(int m, int n)    // greatest common factor
{
    if ((m==0) || (n==0))
    {
        if ((m==0) && (n==0)) return 1;
        if (m==0) return n;
        return m;
    }

    while(m!=n)
    {
        if(m > n)
            m -= n;
        else
            n -= m;
    }
    return m;
}

The next was figuring out how to find the greatest common factor (GCF) of two integers. I've run into this problem before, but where oh where has that bit of code gone? I dunno, but Google finds an example, but it doesn't work. I have to spend several minutes monkeying with it to get it to behave.

That was enough to verify that the Farey addition of fractions works. That is, you generate all of the fractions between zero and one using all denominators from 1 to whatever. Now take any three adjacent fractions on the number line. Add the numerators of the first and last and you will get the numerator of the middle one. Do the same for the denominator and you get the denominator of the middle fraction. You might have to reduce the fraction to make it identical, but the value will be the same regardless.

Verifying that you could use these fractions to generate tangent circles took a little more doing. One way to do it would be to check this out for every new denominator, since at that point the fractions on either side would be the ones you would be forming tangents with. I didn't want to do that, mostly because I was already generating all of the fractions prior to checking the Farey addition, so I need some way to keep track of a fractions "parents" even after multiple fractions had been interposed between them. What I finally settled on was, after generating all fractions for the next denominator, I recorded the values of the parent fractions. Then later I would use these values to locate the original fraction and verify that the generated circles would indeed be tangent.


Tangent Circles and Pythagoras

Verifying that the circles are actually tangent to each other is done by comparing the sum of their radii with the distance between their centers. If these two values are equal they are tangent. If the distance is larger, they are not touching. If the distance is smaller, they overlap.

The distance between centers can be calculated using the Pythagorean Theorem. All you need is the horizontal distance, which is simply the difference between the values of the two fractions, and the vertical difference, which is the difference in their radii. See the above illustration. The orange and purple lines form the sides of the right triangle and the black line forms the hypotenuse.

I fired up my program around 12 hours ago. I gave it some big number to work with, like a 100,000 or something. It has generated over 20 million fractions and it is still running. It seems to be marching on regardless of whether the desktop goes to sleep, or if I am using the computer. I am debating whether I should cancel it or let it keep running. If I remembered what the number was that I gave it, I could estimate how long it is going to run, but I just typed in a one and bunch of zeros. I suppose I should let it run just to make sure it doesn't crash before it finishes.

I've uploaded the source to github if you are interested. I intend to clean up the output so it gives a better picture of what it's doing. When I have done that I will update github.
