MiG-17 - Tumbling Goose showing off his 17’s burners. |
The Mikoyan-Gurevich MiG-17 (Russian: Микоян и Гуревич МиГ-17; NATO reporting name: Fresco) is a high-subsonic fighter aircraft produced in the Soviet Union from 1952 and was operated by air forces internationally. The MiG-17 was license-built in China as the Shenyang J-5 and Poland as the PZL-Mielec Lim-6. The MiG-17 is still being used by the North Korean air force in the present day and has seen combat in the Middle East and Asia.The MiG-17 was an advanced modification of the MiG-15 aircraft produced by the Soviet Union during the Korean War. Production of the MiG-17 was too late for use in that conflict and was first used in the Second Taiwan Strait Crisis in 1958. While the MiG-17 was designed to shoot down slower American bombers, it showed surprising success when used by North Vietnamese pilots to combat American fighters and fighter-bombers during the Vietnam War, nearly a decade after its initial design. This was due to the MiG-17 being more agile and maneuverable than the American F-4 Phantom and F-105 Thunderchief, which were focused on speed and long range combat, as well as the fact that MiG-17 was armed with a gun, which initial models of the F-4 Phantom lacked.
I've been wanting to put together a timeline of Russian jet fighters. I have a hard time keeping all the various model numbers straight. I mean, what are we up to now? 23? 55?

The song expressed Costello's anger after seeing former British Union of Fascists leader Oswald Mosley interviewed on television, attempting to deny his racist past. In the liner notes to the Rhino edition of the album, Costello writes:
"Less Than Zero" was a song I had written after seeing the despicable Oswald Mosley being interviewed on BBC television. The former leader of the British Union of Fascists seemed unrepentant about his poisonous actions of the 1930s. The song was more of a slandering fantasy than a reasoned argument.
And here we are full circle.
POW Travels Across the USA |
It occurs to me that it is very difficult to organize people in order to accomplish something.
The economy is funny. We have il ya beaucoup de companies that employ scads of people, maybe half of whom are making a living wage. There is a large number of people who have invested in these companies and are collecting profits in the form of dividends and increased share prices. We have a handful of people who are making bazillions of dollars either from running these organizations or from having a huge share of the ownership.
We also have a huge number of people who are not employed, not working and not earning any income. Most of those are children and a fair number are stay-at-home mothers.
Then we have the problem people, adults who are not contributing in any meaningful manner other than perhaps picking up beer cans from the side of the road.
Robots are putting more and more people out of work. Just look at Amazon and the automobile factories. Yes, we now have people building robots, but they are a small fraction of the number of people being displaced.
There are new opportunities popping up. With a little talent and persistence, some people are making a living making videos for social media. I dunno, but I suspect the illicit drug business has been expanding faster than the population, so there are more people making a living dealing drugs. I suspect these number of people succeeding in these endeavors is insignificant compared to the general employment picture.
What we need is a financial incentive for people to start companies that can employ the currently unemployed. It wouldn't be a conventional business, it wouldn't be able to compete in the existing economy. Problem people would need training, discipline and, most importantly, motivation. A little religion might help. Asking the government to help would almost certainly assure failure. Suspension of minimum wage laws might help.
Of course, the biggest problem is our corrupt congress that keeps spending obscene amounts of money for the sole purpose of getting kickbacks. Can't say as I blame them. Money seems to be the only thing that anybody cares about any more.

SLAC (Stanford Linear Accelerator Center) |
California Bob reports:
I didn't realize exactly where it was, but I drive right over the 2-mile long Stanford Linear Accelerator (SLAC) every Wednesday on the way to Elsa's pony lesson.
I pointed it out to Elsa; she says they should move it so it doesn't bother the ponies.
SLAC is in the south San Francisco Bay area, south of Menlo Park and Palo Alto. The equestrian center is in the upper right corner of the above image. It is about a quarter inch wide and is sandwiched in between holes of the Stanford Golf Course. Pretty sad that horses have gotten squoze out in favor of golf. I guess that's okay, golf is probably going to get squoze out by apartment complexes built to house the horde of video gamers we are producing.
I was just thinking about the defense budget. Rich and powerful people seek to influence our elected politicians to further their own interests. I inferred that to mean 'to help local businesses get a government contract' or some such. What I am finally realizing is that some of the richer and more powerful people seek to influence our elected government officials to wage war in some foreign land. It's a big step to look beyond our borders, many people are unwilling to look out there. Things are fine here, we've got food to eat, we've got something to complain about, and someone to complain to. What more could you want? Anyway, that's probably why you don't hear much about it. It's kind of a stretch to even think about it. But right now I am convinced that is the way things are. It's the only thing that makes any sense. In any case, that's the way things and the way things will be for the foreseeable future. No amount of rhetoric is going to change that. Besides, as soon as we have a new and 'improved' system, someone will be trying to game the system and we will soon have something really new and 'improved'.
I'm wondering if there might be reasons for the war in the Ukraine that I have not hitherto considered. For instance we know that the armaments business is very happy with the war. They're making money hand over fist building guns and bombs. And the defense guys are happy, they get to test out all their procedures for getting things done, which means the troops get some exercise, get familiar with their equipment and nobody is sitting around mopin'. It's like perfect for our military. They get to skirt the edges of a real danger zone, and if they are going to do that they need to be fully prepared in case the shit suddenly gets hot. Right now, things are relatively calm, Biden, as far as I know, hasn't called for air strikes on Moscow, and Washington D.C. hasn't been bombed. So, relatively calm.
So we might suspect that our domestic armaments industry and our military are very happy with it. But what if there might be a group of people who want to wage this war for another reason? Well, lemme see what I can come up with. Someone might have grown up in a little village somewhere in the disputed region of eastern Ukraine, and he had some kind of a dispute with a neighbor or a family member, and this grievance festered in him for the last umpteen years, but he is finally rich and powerful enough to smite that lying, degenerate, ungrateful twerp. So he tells the higher-ups in government and presto, the hand of god comes down on that village and smites that lying, degenerate, ungrateful twerp.
You can make up your own variations to that. Check out the plots of some of the soap operas out there if you need any ideas. They've got some of the most twisted shit on this planet, and you know that truth is stranger than fiction, so, yeah, run with that.
The one the academics tell us about is the quest for resources. I dunno about minerals. Probably got some oil. Ukraine is a big farming country and they were a big industrial country, so I'm not sure what the resources are. The farming country is still there, it's not going away, but the people and the industrial base are taking a big hit. So maybe the war is intended to take the Ukrainians down a peg, make them more docile. I can't see that being a viable strategy, but maybe there's big money to be made in those conditions. All the big land and industry holders would get forced out and new guys would step in. So a zillion Ukrainians and a zillion Ukraine fortunes are destroyed. Your sacrifice is not forgotten, you made me richer than god, and for that I thank you. Well, we shall see if anybody says anything.

Redpitaya Logic Analyzer |
The Feral Irishman posted a video yesterday where Gardiner Bryant that talks about how evil Google is and how they are invading your privacy and stealing all your secrets. The first few minutes where he gives us some basic background are good, but then we get over into the whole privacy argument. My view is that I don't care.
If you have some kind of information that you want to keep secret, like where your stash of anti-tank land mines or where your chest full of gold doubloons are hidden, don't put it on the net. Period. There was that capo in some gangster movie whose important conversations were all carried out by whispering into people's ears. That's how you keep a secret, not by using a different browser.
Gardiner's argument about Google reminds me of a scene from The Merchant's War by Fredrik Pohl. Our hero, one Tennison Tarb, returns to Earth and walks out onto the street, but the street is packed with people, shoulder to shoulder all jostling each other as they try to go about their business. He happens across on an open piece of sidewalk about ten feet by twenty feet. It's wide open, there is no one there. There are no barriers keeping anyone from entering that area, but still there is no one there. Our dude sees this as an oasis and walks into it where he is immediately assaulted by a loud, specially formulated ad that is designed to make him addicted to some kind of cola. Later on we find these 'oases' are marked with 'prominently displayed' signage due to a court ruling. When these first appeared, it didn't take long for people to figure out there were a hazard to your health and peace of mind and now everyone knows. Everyone except people like our hapless hero.
I see the ads go by when I am surfing the web, but I grew up watching television - I long ago learned to ignore the ads. Perhaps some people are unable to ignore the ads. Those people might be well advised to switch to Firefox.
Anyway, onto more insidious stuff. Something in the video prompted me to look up the Intel Management Engine and what I found is some really low level creepy. From Wikipedia (edited):
The Intel Management Engine (ME) is an autonomous subsystem that has been incorporated in virtually all of Intel's processor chipsets since 2008. It is located in the Platform Controller Hub of modern Intel motherboards.
The Intel Management Engine always runs as long as the motherboard is receiving power, even when the computer is turned off. This issue can be mitigated with deployment of a hardware device, which is able to disconnect mains power.
Difference from Intel AMT
The Management Engine is often confused with Intel AMT (Intel Active Management Technology). AMT runs on the ME, but is only available on processors with vPro. AMT gives device owners remote administration of their computer, such as powering it on or off, and reinstalling the operating system.
However, the ME itself is built into all Intel chipsets since 2008, not only those with AMT. While AMT can be unprovisioned by the owner, there is no official, documented way to disable the ME.
Design
The subsystem primarily consists of proprietary firmware running on a separate microprocessor that performs tasks during boot-up, while the computer is running, and while it is asleep. As long as the chipset or SoC is supplied with power (via battery or power supply), it continues to run even when the system is turned off. Intel claims the ME is required to provide full performance. Its exact workings are largely undocumented and its code is obfuscated using confidential Huffman tables stored directly in hardware, so the firmware does not contain the information necessary to decode its contents.
First, note this statement:
"This issue can be mitigated with deployment of a hardware device, which is able to disconnect mains power."
is contradicted by this one:
"As long as the chipset or SoC is supplied with power (via battery or power supply), it continues to run even when the system is turned off."
Just so we are clear, unplugging the power cord isn't going to stop it. The battery on the motherboard is enough to keep it alive. If you really want to stop you need to unplug it from the internet and the power outlet. And put it in a Faraday cage so no radio (like Cell phone, Wifi or Bluetooth) signals can get through.
If you really wanted to know what was going on, you'd want to know what was in those Huffman tables. Figuring that out might be a bit of a trick. You could, if you had good people skills, go out and talk to Intel employees until you found the guys who designed these tables and then using dastardly secret agent techniques get them to spill the beans. Problem with this method is that even if they hand over the tables, they might not be correct.
The other way, the hammer and tongs way, is to hook up the chip to a logic analyzer, step through the code and record what the relevant pins are doing. Might have to write some special code to exercise the chip in specific ways to get it to exercise the full extent of those tables.
You are still not done because now you get to look at all those traces and try and deduce what kind of logic produced them.
If you have gotten this far and you also happen to have the secret table that you managed to squeeze out of the Intel engineer, you are liable to find that the table does not match what you found. Could be a deliberate error, or an error made in translating to hardware.
Which reminds me of the bit of speculating I did about back doors in exported weapons. They could easily be there, in any equipment with any kind of solid state electronics and you would never know without doing a microscopic, destructive, layer by layer scan of all of the electronic chips.
Connections - New York Times Game |
Back when I was selling Chevies, in the mid/late-80s, I sold a Chevy Nova (the NUMMI-built Toyota Corolla that was about to become the Geo Prizm) that had been sitting on the lot for a while.It needed an ashtray, so while the customers were in the box with the F&I guy, I ran back to the parts department and asked for a Nova ashtray. The parts counter guy asked what color. “Dark brown”, I replied.He came back and deposited the bagged part on the counter, saying “Here’s your Midnight Driftwood ashtray.”I’ve had a low-key fascination with automotive color names ever since.
I've put up 517 posts so far this year. There are also a couple dozen posts I started but haven't gotten around to finishing. Problem is that some of these posts require a well functioning brain. Many posts don't: steal a picture, write a caption and a couple of sentences about it and move on. Some require more than two brain cells in order to communicate what's going on in my head, and if my head is foggy, that doesn't happen, so those posts become drafts. Very sad. Maybe things will improve now that my hip joint got replaced.
Imagine you're in a gangster movie from 40's or 50's and a copper comes into your office and you're talking. It could be hostile talking or pleasant conversation, it doesn't matter. Whatever, you and the copper are talking and he asks you about the matchbook on your desk. What do you tell him? Well, let me tell you what I'd tell that copper, I'd say* 'What? You don't have one on your desk? It's like if you carry a pocketknife. It's like being a Boy Scout, be prepared'.
* now that I've had fifteen minutes to ruminate on the situation. I went through a zillion little scenarios before landing on this one. I just changed the tense on that verb. Because somebody said: active voice is better than passive voice? It was 'I landed' and now it is 'landing'. Is 'landed' passive and 'landing' active?
Disassembled Sump Pump & Tools Tally-wacker is at the top, underneath the awl and the screwdriver |
Utilitech 1/3 HP Pedestal Sump Pump |
I took the sump pump apart yesterday. It was surprisingly easy. The screw heads were rusted, but they were screwed into a plastic body so they came out easily. The Phillips head cross on the head of one of the screws had been completely obliterated. If you looked carefully, you could make out where it had been. I had to use my custom talley-wacker, carved from a genuine imitation war-surplus machete (that got broken in the heat of battle with a stupid tree) to restore the cross. Put the tip of me talley-wacker in the center of the screw, align the blade with one leg of the Phillips head cross and give a wack with my patented cheater pipe (specially flattened to fit the handle of of Craftsman 3/8" drive ratchet). Repeat three more times for the other three legs and I had enough of a cross to turn the screw. Screws-in-plastic is great. With a pump with any kind of metal body, those screws would have been so corroded it would have been an even bet whether you could get them out or they would break off. The plastic parts on this pump made disassembly a breeze.
The motor is connected to the impeller with a plastic drive shaft. It looked like it was secured with a blind roll pin. Roll pins usually go all the way through, but there's always someone looking for a way to cut corners. Only after I tried drilling one out did I realize it was an Allen screw. Where did my shop bifocals get to?
I could have looked for parts, but I suspect it would have been a pain in the neck, they'd have to be ordered from lower Elbonia and take three weeks to get here via FedEx (service from Elbonia is notoriously slow). Or I could just order a new pump with an integrated SWITCH for $60 from Amazon and have it here tomorrow.
Actually, the reason I didn't want to repair the pump is because it had fallen over and I suspect that is what led to its demise. I have a five gallon bucket embedded in a gravel pit in the pump room. There is a french drain that dumps into this gravel pit. There used to be water coming in from this drain, but then I got some serious drain control around the front of the house and the water problem diminished considerably. Still, the five gallon bucket is full of water, so I need a pump.

Previously I had used little short pumps with a float attached via a length of power cord. The cord would let the float flop around. There is a switch inside the float. When the float finds itself in the upward position, the switch closes and the pump turns on. When the water level falls, the float falls. When the float is in the downward position, the float opens and the pump turns off. They work fine except the pump is sitting in a five gallon bucket and if the pump shifts it will trap the float against the wall of the bucket and it will never turn off. Burned out two pumps that way.
The bucket isn't much bigger than the pump, and vibration from the motor running was probably enough to cause it to shift position. I don't understand why this last pump fell over. Normal operation shouldn't cause that. Poltergeists, I suppose.

A couple of headlines that hit my eye this morning.
US national debt passes new landmark
US national debt is now $33 trillion dollars. What does that even mean? Let's take a look.
Price of gold in 1960: $36.50 per ounce
Price of gold now: $1,954.20 per ounce
National debt in 1960: $286 billion
National debt now: $33,000 billion
National debt now: 527,763 tons of gold
National debt in 1960: 244,863 tons of gold
Why pick 1960? Peak America? Because it's a round number? Because I was only nine years old and didn't know any better? Because I used it the other day looking at car prices?
Anyway, measuring the national debt in dollars, it is 115 times larger than it was in 1960, but if you measure it in gold, it is only slightly more than twice as large. Which means the dollar is only worth about 2% of what it was in 1960. It likewise means that that Popsicle that cost 7 cents at the corner store in 1960 should now cost three and half bucks. There might be fancy concoctions at your local 7-11 that would cost that much, but I suspect that is the high end.
What ho! Is something actually going to happen? Silly boy, the story is about Israel, not about the Rhinos suddenly growing a spine.
Most Valuable Professional Sports Teams |
Unlike my wife, I am not a big sports fan. I can watch a bit of professional basketball and college football, because that's what she watches, but if the competition isn't close I soon lose interest. I find the ads during football games more interesting, probably because we're starting a new season with a new bunch of ads. I do not understand the attraction. Well, I sort of do, we are basically pack hunting animals and sports are a civilized way of channeling those instincts into something harmless but entertaining. There have been occasions when I have gotten swept up in the excitement, but there haven't been many and they don't last long.
Somebody told me about a friend of a friend, a blue collar worker, spent $21,000 for Super Bowl tickets one year. I cannot fathom making such a purchase. 70,000 seats at $8K a piece is half a billion dollars, and that's only for one game. What an empire.

Nephew Nick seems to be getting serious about fishing. He's been working on other people's boats for a few years and now he's thinking about buying his own. This boat is in Cordova, Alaska, home to a big fish processing plant. There are no roads to Cordova and this boat is not suitable for open water, so presumably he would stay in that area and fish the inlets and the Copper River (Wikipedia).
Copper River and Cordova, Alaska |
There is a small room in the basement under our house, the pump room, that holds a sump pump and a trash pump. The space under the stairs adjoins it. That space is good for storing stuff you might need one-of-these-days. Since you have to go through the storage room to get to the pump room and then go around the corner to get to that space, it's easy to forget about it. My wife and I did talk about it briefly last week.
When we built the house, there were some pieces of flooring left over that we stashed there just in case the flooring ever got damaged and we had to repair it. Ten or twenty years ago we got the house recarpeted and we did the same thing over again. Now we're remodeling which mean changing out the floor coverings again. Yesterday the trash truck was here to pick up the remodeling debris and my wife got the bright idea that we should haul all of that old carpet out of the hidey-hole and add it to the trash pile. It was more work than I've done in a while and it pretty much wiped me out. I don't know whether it's because I am old of because I became debilitated from having a bum leg for the last year (or two?). Whatever, we got it done so now I have more space put stuff. Yay.
I'm reading A Fire Upon the Deep by Vernor Vinge (Goodreads) and in Chapter 35, page 365, they are talking about setting up a park inside a 200 meter diameter cavern that they have carved out of a giant diamond. The diamond is roughly cubical and measures about a thousand meters on a side. Don't ask me where they got it, probably found it out wandering around in the asteroid belt of the On-Off star system. This diamond rock, along with all their stuff, is floating around in space at L1 which sits them hanging in limbo between the planet and the star.
Now they are talking about putting a lake in this park, a park that will only have microgravity at best and I'm thinking how could this possibly work? If you leave it undisturbed and there is the least hint of gravity or centrifugal force, it should form a pool on one side of the cavern, but you so much as breath on it you're liable to get Tsunami. Mr. Vinge wants them to drop a bunch of micro-widgets into the lake and the, through the power of modern computers, will counteract all the wrong impulses in the water and force it to behave. Okay, Vern, I think you've stepped over the line here.
Maybe I'm being too hasty. Every seen the ripples generated in water when a strong audio sound is applied? So maybe having a battalion of micro-actuators could be made to counteract any activity on the surface. But we've still only got micro-gravity to pull the water back down. I could see this quickly getting out of control. The only solution I see is start pushing this giant rock with a rocket, which could happen, they have some big rockets in this story. Well, that is until someone invents some kind of gravity control, which I don't think is ever going to happen. Centrifuges, rockets and mass are going to remain the sole methods of affecting gravity now, forever and always.

It’s almost as good as the trick where someone ends up manning the antiaircraft guns whilst scantily clad, which Hamilton was also good at.
So I had to go find a pic. Lots of pics out there of sci-fi babes. Many of them are holding guns, but not too many of them wielding guns in a combat setting.
Ventusky Hurricane Lee |
The film centers on a group of four down-their-luck European men who are hired by an American oil company to drive two trucks over mountain dirt roads, loaded with nitroglycerine needed to extinguish an oil well fire.
The name Sorcerer comes from one of the dilapidated trucks they are using to transport the explosive, in this movie the explosive is old 'sweating' dynamite that is unstable.
There is very little dialog and most of it is unintelligible, I never developed any empathy for any of the characters.
The film is almost entirely action. There are two parts to the movie. In first part we get four short stories about how the four men got into the trouble that forced them to flee to this jungle hamlet. The well dressed man shoots a man in a room at a hotel with a gun equipped with a silencer. The curly haired guy is a freedom fighter/terrorist whose group has been found out. The Frenchman had been engaged in some shady business deals and if he can't come up with a large sum of cash to make things right, he's going to jail. Roy Scheider and three other thugs rob a Catholic church in New Jersey where they are consolidating the donations from several churches. Roy crashes their get-away car in spectacular fashion. He manages to crawl away and get on a ship headed for parts unknown.
These four end up in a shanty town in the jungle that exists only because an American company is drilling for oil and they need workers to build the pipeline and operate the drilling rig. Then we have the explosion and fire at the drilling rig. If they can't put out the fire and get the rig back into production, the whole project is going to get canceled, so they are desperate for a way to put out the fire. Then someone turns up this old stash of dynamite sitting and rotting in an old shed. Problem is, the shed is 200 miles from the fire. They consider flying it with helicopter, but they suspect the vibrations would set off the explosive. No sense risking an expensive helicopter when we have a bunch of old, junk trucks and a bunch of desperate men willing to drive them.
One highlight is the scene where a truck is crossing a gorge on a very rickety wooden bridge that is collapsing out from under them. Another is where they have to cross a river on a very sketchy suspension bridge in driving rainstorm. Then there's the scene where they rig up a booby trap to blow up giant tree trunk that has fallen across the road.
Three of the four men die during the trip. Roy survives long enough to collect the promised loot, but instead of leaving he stops to dance with the washer woman. And who should show up? The imported hit man sent by the guys in New Jersey.
Cummins and his first diesel |
THE LEGACY OF THE CUMMINS NO. 8 RACE CAR by Michael NagelMay 15, 2015Of all the Cummins race cars, none is as well-traveled as the 1931 No. 8 Cummins Diesel. From the famous Indianapolis speedway to a tour round the world, the No. 8 car was the model for efficiency and reliability.Cummins founder Clessie Cummins originally installed his 4-cylinder model U engine in a Duesenberg chassis and in February 1931, drove it to Daytona Beach and set a new diesel speed record averaging 100.755 miles per hour (mph).In May of 1931 Clessie took the Cummins-Powered Duesenberg as the No. 8 Cummins Diesel to the Indy 500 and finished 13th with an average speed of just over 86 mph. It was the first car in racing history to complete all 500 miles without any pit stops.The No. 8 car wasn’t retired after the race. Cummins founders W.G. Irwin and Clessie Cummins drove it on a European tour through France, Monaco, Italy, Germany and England to promote the efficiency and reliability of the diesels.
So now I'm looking for some information about this Model U engine. Wikipedia coughs up:
The Cummins Engine Company was founded in Columbus, Indiana, on February 3, 1919, by mechanic Clessie Cummins and banker William Glanton Irwin. The company focused on developing the diesel engine invented 20 years earlier. Despite several well-publicized endurance trials, it was not until 1933 that their Model H engine, used in small railroad switchers, proved successful.
So two years after the founders made their world tour, business came their way. So now I'm looking for this Model H engine, but I'm not getting anywhere. Probably because there's only three guys who have the info and they're so old they don't even know about the internet. So instead of anything useful, we get to watch this even older engine get run through it's paces.
Can you imagine trying to set up a factory to build an engine? Now-a-days to be competitive, you would probably need a billion dollars. There are a few specialty shops building engines, big and small. I wonder if any of those small shops are casting their own iron blocks? Casting iron is a big deal, not like casting aluminum. That crazy old coot who rode the The World's Fastest Indian was casting pistons in his backyard. Casting iron takes a lot of heat. How much, you ask? Let's see what we can find.
From THUNDER SAID ENERGY:
A good rule of thumb is 25 kWh of useful energy to heat each ton of material by each 100ºC. (1) Thermodynamics 101. Heating and melting materials requires energy, inducing particles to vibrate more (specific heat) and ultimately to break the bonds that hold them together as a solid or liquid (latent heat).
Density of iron is 7.874 grams / cc. Density of aluminum is like 2.7 grams / cc, so iron is three times as dense as aluminum so the same size object would weigh three times as much and require three times as much energy. Except iron has a much higher melting point than aluminum. Aluminum melts at 1200 degrees C, iron melts at 2800 degrees C, so, assuming we are heating the metal on a cold winter's day, iron is going to take:
(7.874/2.7) * (2800/1200) = 6.8 times as much energy to heat to the melting point as aluminum.
