LETTERS FROM AN AMERICAN

April 10, 2024 (Wednesday)

HEATHER COX RICHARDSON

APR 11, 2024

Prime minister Fumio Kishida of Japan and his wife, Yuko Kishida, are in Washington, D.C., tonight at a state dinner hosted by President Joe Biden and First Lady Jill Biden. The dinner is part of a state visit, the fifth for this administration.

Biden and Secretary of State Antony Blinken have worked to strengthen ties to countries in the Indo-Pacific to weaken the dominance of China in the region, and Japan is the key nation in that partnership. “We celebrate the flourishing friendship between the United States and Japan,” Dr. Biden said Tuesday. “Our nations are partners in building a world where we choose creation over destruction, peace over bloodshed, and democracy over autocracy.”

During talks today, Biden and Kishida committed to strengthening the defense and security frameworks of the two countries so they can work together effectively, especially in a crisis. The new frameworks include intelligence sharing, defense production, satellite cooperation, pilot training, cybersecurity, humanitarian assistance, and technological cooperation. Affirming the ties of science and education between the countries, the leaders announced that two Japanese astronauts would join future American missions and, Biden said, “one will become the first non-American ever to land on the moon.” 

That cooperation both takes advantage of and builds on economic ties between the two countries. In a press conference with Kishida on Wednesday, Biden noted that Japan is the top foreign investor in the U.S., and the U.S. is the top foreign investor in Japan. Microsoft, Google, and Amazon have announced investments of $2.9 billion, $1 billion, and $15 billion respectively in Japan over the next several years, largely in computer and digital advances. Japanese corporations Daiichi Sankyo, Toyota, Honda Aircraft, Yaskawa Electric Corporation, Mitsui E&S, and Fujifilm announced investments in the U.S., primarily in manufacturing.

In a press conference, Kishida told reporters that “[t]he international community stands at a historical turning point. In order for Japan, the U.S., the Indo-Pacific region, and, for that matter, the whole world to enjoy peace, stability, and prosperity lasting into the future, we must resolutely defend and further solidify a free and open international order based on the rule of law.”

“This is the most significant upgrade in our alliance…since it was first established,” Biden said. While he noted that lines of communication with China remain open—he spoke with Chinese president Xi Jinping last week—the strengthening of ties to Japan comes in part from concern about the Chinese threat  to Taiwan, a self-ruled island that the Chinese government considers its own. Leaders are increasingly concerned that the Republicans’ refusal to fund Ukraine has emboldened not only Russia but also China. 

Tomorrow, President Ferdinand Marcos, Jr., of the Philippines will join Biden in a bilateral meeting before Marcos, Biden, and Kishida join in the first trilateral meeting of the three. Kishida will also address a joint session of Congress.

Kenneth Weinstein of the Hudson Institute, a conservative think tank, suggested today that Japan “has quietly become America’s most important ally,” “playing a central role in meeting our nation’s principal strategic challenge: the threat posed by the People’s Republic of China, especially the defense of Taiwan.” Weinstein also notes that Japan’s longstanding engagement in Southeast Asia means it has “forged relations of deep trust” there among countries that often eye the U.S. with deep distrust. 

Outside of news about the Japanese prime minister’s visit, U.S. news today was consumed by reactions to yesterday’s decision by the Arizona Supreme Court to permit the enforcement of an 1864 law that is currently interpreted as a ban on all abortions except to save the mother’s life. 

President Biden issued a statement condemning the “extreme and dangerous abortion ban,” calling it “a result of the extreme agenda of Republican elected officials who are committed to ripping away women’s freedom.”

“Vice President Harris and I stand with the vast majority of Americans who support a woman’s right to choose,” he continued. “We will continue to fight to protect reproductive rights and call on Congress to pass a law restoring the protections of Roe v. Wade for women in every state.”

Vice President Kamala Harris will travel to Tucson, Arizona, on Friday to respond to the ruling. According to Hans Nichols of Axios, she had been planning to travel to Arizona anyway but quickly shifted her visit to make it a campaign trip, allowing her to comment more freely on Trump and the Republicans who were responsible for the overturning of Roe v. Wade and the imposition of abortion bans since. 

Harris has been out front on the issue of reproductive rights, meeting more than 50 times with groups in at least 16 states since the Supreme Court handed down the Dobbs v. Jackson Women’s Health Organization decision in June 2022, overturning the 1973 Roe v. Wade decision that recognized the right to abortion. This year, on the January 22 anniversary of the Roe decision, she announced a “Fight for Reproductive Freedoms” tour. 

“Extremists across our country continue to wage a full-on attack against hard-won, hard-fought freedoms as they push their radical policies,” she said. “I will continue to fight for our fundamental freedoms while bringing together those throughout America who agree that every woman should have the right to make decisions about her own body—not the government.”

Yesterday illustrated what the overturning of Roe v. Wade has wrought. The Republicans who were celebrating that overturning two years ago are now facing an extraordinary backlash, and they are well aware that Arizona is a key state in the 2024 presidential election. Former president Trump has boasted repeatedly that he was responsible for nominating the Supreme Court justices who overturned Roe, supported a national abortion ban, and even called for women who get an abortion to be punished. 

But today he swung around again, telling reporters that he would not sign a national abortion ban if it came to his desk. To be sure, as Josh Marshall of Talking Points Memo notes, there’s no reason to think he wouldn’t sign such a bill, but the fact he is denying that he would and is running away from the issue shows just how much it hurts the Republicans with voters. 

Harris’s trip, along with Biden’s constant travel, shows a willingness to crisscross the country to meet voters that dovetails with new statistics out about the Biden-Harris campaign. While Trump has largely stayed at Mar-a-Lago, has fewer than five staffers in each of the battlefield states, and has closed all the offices that made up the Republican National Committee’s minority outreach program, the Biden-Harris campaign has 300 paid staffers in 9 states, and 100 offices in regions crucial to the 2024 election.

Pagani Huayra Roadster (1 of 100). 

The Pagani Huayra Roadster is a luxury convertible sports car built by the Italian manufacturer Pagani Automobili S.p.A. The Roadster is the open-top version of the Huayra, a mid-engined supercar known for its advanced engineering, aerodynamics, and handcrafted details. The exterior of the Huayra Roadster is a work of art, featuring flowing lines, sharp angles, and aerodynamic curves. It is constructed with a mixture of carbon fiber and titanium, which makes it lightweight yet strong. The car features active rear and front wings that adjust their angles based on speed and driving conditions, helping to increase downforce and stability. The Roadster also has a unique, teardrop-shaped cabin that is designed to provide maximum visibility and a feeling of spaciousness. Under the hood, the Huayra Roadster is powered by a 6.0-liter V12 engine that delivers 754 horsepower and 738 lb-ft of torque. This engine is paired with a seven-speed automated manual transmission, which allows for quick and smooth shifts. The Roadster has a top speed of around 230 mph and can go from 0 to 60 mph in just 2.8 seconds. The interior of the Huayra Roadster is just as impressive as its exterior. It is handcrafted with premium materials, including leather, carbon fiber, and aluminum. The car features a fully digital instrument cluster, a high-end sound system, and a bespoke infotainment system that is tailored to each individual owner's preferences. Only 100 Huayra Roadsters were ever built, making it an incredibly rare sight on the road and a guaranteed head-turner. Thanks to the great owner community and the events organized by Pagani themselves, there is almost always a great reason to get the car out and enjoy it on the sunny Italian roads for example.

The Importance of High-tech Rapid Prototyping

In the industrial industry, precision is not only desirable—it is essential. Consider a situation in which parts of a jet engine are even marginally machined incorrectly or misaligned. The repercussions can be disastrous and might cause the engine to fail in midair. Precision becomes the key to success in sectors like aerospace, automotive, and medical where safety and dependability are non-negotiable. Put simply, it's the capacity to manufacture parts or components that precisely conform to given dimensions, tolerances, and quality requirements. It takes state-of-the-art equipment, painstaking attention to detail, and highly competent operators to achieve this degree of accuracy. This is the sweet spot for Precision CNC Machining.

So how precisely can CNC machining accomplish such high precision levels?

Computerized Control: Advanced computer software is the brains of CNC machining, translating digital design requirements into exact motions and orders for the milling tools. This removes the possibility of human error and guarantees the highest level of precision in each cut, drill, and mill.

Superior Quality Equipment: Modern spindles, tools, and cutting implements that are designed to provide exact results are standard on CNC machines. These devices may operate at extremely tight tolerances, which are sometimes expressed in microns, guaranteeing an accurate reproduction of even the minutest features.

Consistency: The ability of CNC machining and High-tech Rapid Prototyping to manufacture similar components with little variance is one of its main advantages. A machine program that has been developed and tuned may be repeated endlessly with reliable outcomes. In fields where stability and dependability are critical, this degree of constancy is priceless.

Advanced Techniques: Multi-axis milling, turning, EDM (Electrical Discharge Machining), laser cutting, and other state-of-the-art methods are all included in CNC machining. With unmatched accuracy and efficiency, manufacturers can handle complicated geometries and materials thanks to these procedures.

Quality Assurance: CNC systems frequently include integrated quality control mechanisms including automated inspections, feedback loops, and real-time monitoring in addition to accurate machining. This reduces waste and rework by guaranteeing that any deviations from the intended standards are quickly identified and fixed. It is impossible to exaggerate the value of accuracy in production. Precision by Precision CNC Machining Manufacturer plays a crucial role in today's competitive economy, as it ensures everything from satisfying regulatory requirements and consumer expectations to assuring product performance and dependability.

tbh i've purposefully avoided posting anything about AI art onto any of my public accounts because i just know my opinions on it wouldn't be popular. and i'm saying this as someone who is really, REALLY passionate about art - creating and critiquing art are literally my lifelong passions. but so much of this AI art debacle has become about people making bizarre declarations about what is or isn't "real art" - defining it using nebulous metrics like "the soul" and such.

the ethical issues with AI art as it currently exists are undeniable, and i wish people would focus on that instead of trying to define what "real art" is. because the thing is, gatekeeping the definition of "real art" has been going on for centuries! there are still people today who think video games aren't real art, even. a few decades ago, there were people who thought movies (cinema, film) couldn't be real art! the definition of art evolves and grows, and i resist and question any effort to suppress that.

some thought exercises for people who think they can define "real art" so simply:

is animal-created art real art? are pufferfish nests real art? are elephant paintings real art? does an animal have to reach a certain threshold of intelligence in order for its creations to be considered art?

is duchamp's fountain real art? for those unaware, this was a mass-manufactured urinal that the artist signed and submitted for an art exhibition as is, with no alterations aside from signing it with a marker.

is digital art real art? remember that digital art comes from machines translating human input into pixels on a screen. is this an acceptable use of machine intervention in art creation because the software performing these actions was not created using machine learning? is it because the human has more perceived control over the output?

is photography real art?

is music real art? is music composed using digital software real art? if a song utilizes a heavy amount of sampling, is it still real art?

many digital artists use software that allows them to create layers with filter options that adjust the colors of the layers beneath them using an algorithm (overlays like multiply, screen, etc). in this case, the colors of their images have been digitally altered by a piece of software in ways that most artists don't fully understand. is the image created as a result of this process still real art? can the artist claim full human ownership of the colors, which were digitally altered using a machine algorithm? would your opinion on this change if the machine algorithms behind overlay layers were created using machine learning?

some digital artists make use of "pen stabilization", a type of software algorithm that manipulates tablet pet inputs into a steadier curve to remove jitter. are lines drawn using heavy amounts of stabilization still the artist's? can the artist claim human ownership of lines drawn using near 100% stabilization?

many digital artists will use stamp brushes to get past having to repeatedly draw a static pattern, such as to fill the leaves in a tree. this is essentially a glorified version of copy and pasting repeatedly, except that a software algorithm introduces semi-random rotations and color jitter to give a more natural appearance. is a tree drawn using this process still real art? does your opinion on this change if the artist created the stamp themself, vs downloading it from another artist? does it change depending on how granular the artist was with making manual adjustments to the stamp outputs?

what proportion of an image is allowed to come from stamps, filters, and software tool usage before it stops being real art? is photobashing real art? what percent of an image has to come from freehand drawing for it be considered real art?

are edits of other people's art real art? does your opinion on this change if the editor had the original artist's consent? what percentage of the pixels has to have been changed by the editor before it is worthy of being considered real art?

one popular usage of "AI art" is to apply an "AI filter" over an existing image, which takes a drawing and then utilizes a machine learning based model to alter the image pixels. is an image created using this process real art?

if a person generates an image using a machine learning model, such as stable diffusion, and then draws over that image, is the resultant drawn-over image real art? what percentage of the pixels has to come from a human hand for it be considered real art? what if it was only 1 or 2 pixels that were manually manipulated? what if the only thing a human adds is an overlay filter?

if a person generates an image using a machine learning model, such as stable diffusion, and has very strong intent and emotion about how they want the resultant image to look, tweaking their prompts and specifically trying many different options before the output is in accordance with their vision, why is this not real art? is it because they did not specifically intend on every single pixel in this image? what percentage of pixels in an image has to have specific human intent for an image to be considered real art?

in 3d animation, physics simulations are used to calculate the positions of moving objects, and then artists manually adjust the outputs in accordance with their desired product. spider-verse, for example, was partially created using a combination of "traditional" software and some in-house created machine learning models. is the animation created using this software real art? does it only become real art once a human has gone in and reviewed it? is an individual frame of animation that hasn't been reviewed by a person and was generated via software and simulations not real art? would your opinion of this change if the machine learning models had not been created in-house? would it change if the training datasets had been acquired unethically?

if a traditional artist closes their eyes and splashes paint at a canvas, is the resultant splash of paint real art? if the artist had no emotion or specific intent when casting the paint across the canvas, is this still real art? are pollock paintings real art?

can a mistake be real art? if an artist tips over a can of paint and creates a beautiful spill, could they present the canvas as is with no further alteration, and that resultant image be considered real art?

can art styles be "stolen"? do artist own their art styles?

do you support copyright law? how much inspiration is allowed to be taken from something before it is considered plagiarism vs derivative, and should derivative works be punished?

what is the precise difference between the way ai art "steals" art styles, vs the way a human being takes inspiration from them? remember that many machine learning models take directions and instructions from humans, and often do not learn in a vacuum devoid of human intervention.

some very popular artists, who i will not name, have been accused of having "soulless" art. these artists "mass-manufacture" their images to look very similar and consistent and have seen a lot of financial success as a result of their repetitive works. is their "soulless" art still real art, even if it was made completely without the use of AI technology?

were you bothered by images generated by dall-e, back before stable diffusion became popular? did you consider images generated by dall-e to be art? did you consider dall-e to be unethical?

what is it about machine learning models that separate any software derived from it from software made without the use of machine learning? why is the usage of an art program that did not come from machine learning seen as ethically superior? what is ethically wrong with machine learning models? is it only if the training dataset was scraped without acquiring explicit consent? is it only if the learning was performed supervised vs unsupervised?

can software itself be art? can you find artistry in the way a program has been written - in the lines of code created by a human? in the intent and emotion of the programmer who crafted a piece of software?

please note i'm not trying to be condescending by asking these, and don't assume you know my answers to these questions, either. these are questions i asked myself when i was chewing through these debates and trying to quantify exactly what i found so objectionable about many of these "what constitutes 'real art'" takes.

reblogs off because i don't want to engage with strangers on this topic. i'm open to debate but only if you're going to be civil about it. please remember that i'm an artist too.

First serially produced Grey Wolf is almost complete

Fernando Valduga By Fernando Valduga 12/06/2023 - 08:48 in Helicopters

At the Leonardo Helicopters production site in Philadelphia, the final touches are being made on the first MH-139A "Grey Wolf" for the U.S. Air Force.

The start of series production of the first batch, consisting of thirteen helicopters, took place in March. The MH-139A is a co-production between Boeing and Leonardo.

The helicopter is derived from Leonardo's popular civilian AW139. Boeing and Leonardo jointly participated in a U.S. bid to find a successor to eighty UH-1N Huey helicopters operated by the U.S. Air Force Global Attack Command. In 2018, the two manufacturers were informed that the choice fell on the MH-139A.

The new Grey Wolf helicopter was certified in 2022 and is scheduled to be delivered for operation in 2024.

Combining its experience in integrating specialized military equipment with Leonardo's proven design, Boeing expands its commercial derivative aircraft business and provides the U.S. Air Force with a highly capable product with the best value.

Finally...

I was looking for a really good shortwave receiver for at least a decade -an old tube equipped one of course. The problem getting one nowadays is that they were only produced in small numbers half a century (or more) ago, since then most are scrapped, botched, altered or corroded cause of bad storage -or all together. So if you have the chance getting one today you most likely will buy a 'construction site', needing hundreds of working hours for restoring it in a good working condition.

But after a looong search finally i had real luck. A big wooden crate was delivered on a pallet.

In this crate was one of the -for my opinion- ugliest shortwave receivers ever built, but at the same time also one of the best ones: a Rohde + Schwarz EK07.

Built in 1958 this one was a storage unit from the German Army. Well stored, regularly maintained and serviced, not altered, not botched, never used. So it is in nearly mint condition. It wasn't cheap but getting my hands on this was just sheer luck. Without doing anything: it's in perfect working order. No potentiometer, no switch crackles, every tube checks new -of course you can check all the tubes in the radio itself without removing them.

The manufacturer is more known for it's precision Lab-Equipment and less for it's shortwave receivers. This is also because their receivers weren't consumer or amateur gear, this was pro gear by any means. They were used in applications like coast guards or military surveillance and such. Always things where equipment costs doesn't matter -only the outcome. So back in 1958 when this unit was manufactured you could buy at least two brand new cars for the same amount of money. In exchange for this you got a masterpiece of german engineering and craftsmanship -and also an electro-mechanical nightmare if anything fails and you're not absolutely familiar with it's guts.

Fancy? No, there's absolutely nothing fancy on these. These are absolute workhorses, designed for doing an important job 24/7/365 for decades. Just take a look to that bandswich gear in the photo above. How often you have to switch over the bands until this would be worn out? Millions and Millions of times... And nope: this dark residues at that drum on the left and box below isn't mold or such. These are completely silver plated so it's just the darkened silver.

As you may see, most of the structural parts are made of die-cast and aluminum, so from the materials used it's relatively light weight. But all that built-in sturdiness and shielding adds up to staggering 147lbs/67kg. It's only a receiver, not a transmitter or a power amplifier.

Tubes... and more tubes

If you're not familiar with tube radios: your average AM (and shortwave) Radio from the 50's or 60's used 4 tubes (without the rectifier if this was a tube). Your trusty Hammarlund or Yaesu shortwave receiver from that time would have somewhat from 8 to 12 tubes -and these were quite good and sensitive receivers! This Rohde + Schwarz counts 28 tubes.

Some tubes here, some there, all fully shielded. But why the hell that much? The answer is quite simple: stability. On every count. Constant and stable gain over all bands and for a looong service time, stunningly stable VFO frequencies and all that stuff. No, they used no consumer tubes like in your TV or such. All of them are out of the 'commercial'-tube-series with a guaranteed service life of at least 10000 hours like in every aircraft of that time or such. Failing was not an option, this HAD to work.

Speaking about stability and accuracy:

this of course isn't digital stuff -it's purely analog. In the pictures below you can see the dials. Just add both frequencies and you know where you are -here on 29.630MHz or 29630kHz.

As you see: your readout is easily accurate down to less than 500Hz. So you can read at least 500Hz out of 29630000Hz. With other words the accuracy of your readout is 0.001687% in this case. Your average modern digital multimeter would be proud if it came only near to this 65 year old contraption.

Of course that large dial in the picture on the left isn't the only one. There are 12 of 'em, mounted on a drum and rotating according to the selected band. Giving you a simple S-Meter like in other shortwave receiver was of course also not possible.

Instead they provided you with a Voltmeter which displays directly the input voltage at the antenna input -and the threshold voltage for the 'Squelch' (if you have set that) which isn't a normal squelch. If activated it doesn't cut your Audio, it reduces the Gain instead with a settable time constant, so it acts more like a active noise cancelling between any signal -also between any dash and dot if you're receiving CW (Morse Code). Besides that you can choose your IF-Passband between 150Hz and 12kHz, have a absolutely stable BFO, a good Envelope Detector for AM-Reception and a perfect Audio Stage - that's all.

Speaking of the Audio Stage: 2W undistorted output power from a single end class-A is more than you need with a good speaker. McIntosh ® would call that circuit 'Unity Coupled', further a E88CC for the Audio-Preamp. We're talking about an Shortwave Radio, not an 'High-End' Audio Amplifier. Wanna take recordings of what you hear? No problem: here's your Line-Output, symmetric, 600 ohms, transformer coupled and with +10dBm (if you want) and in accordance to all Studio-Standarts. Sound quality for AM Broadcasts? With a passband switchable up to max. 12kHz for the IF better than the majority of stations can provide.

Precise?

So far so good, but what's about the heart of every shortwave receiver: the Oscillator or VFO? How stable and precisely does it beat after 65 years?

In your trusty -and quite good- Hammarlund or Yaesu amateur Radio from these days the VFO usually is equipped with two tubes: the Oscillator itself and the buffer amplifier -both sometimes also united in one bulb. If i hadn't lost track here they used 12 -and tons of other stuff. So that frickin VFO has a component count which is easily about the order of a complete shortwave receiver.

What the hell is all that stuff about -and wtf they had for breakfast back then? The answer is again simple: precision and stability.

As i said: this thing is 65 years old and i touched nothing. Of course I checked how much it's 'off' in terms of the frequency. After warming up for 20 Minutes i checked it every 1000kHz from the bottom to the top of its range. It was a bit different between all points, at some less than 50Hz and about 1kHz worst case.

My Lab-Equipment is quite good and precise, but for these low errors the tolerances of the measuring equipment has absolutely taken into account. So i made a separate measurement only for 10MHz -with the aid of a frequency standard sourced from an atomic clock. So this was 'the real thing'. After warming up for an hour i measured for 15 Minutes. The deviaton was between -717 to -722Hz. Including the error of the dial. This means frickin' 71.7...72.2ppm. PPM -parts per million! 65 years after manufacturing.... Just absolutely stunning -and with what freaking kind of equipment they had calibrated this back then??? Just have in mind: this is pure analog goodness, not a modern PLL. How the f***k they got there? Here's the clear link between a manufacturer of high-grade Lab Equipment and a shortwave receiver. I'm just stunned over the knowledge of the engineers who designed that circuit back then and the precision this was built.

All without doing anything and all it's original capacitors. Yap, i could realign that but tbh it's just wayyy to less been worth the effort. So it will stay as it is.

Nope,

you're not provided with that fancy stuff your new digital or SDR may have on board. There's no notch filter, no panoramic display -not even SSB! Why the hell they just 'forgot' all these things? The answer is easy: it's modular. The EK07 is just the 'mainframe', everything else you wanted to have can be added as external components you had to buy separately -also for tons of money of course.

Wanting SSB? Just add this:

35kg/77lbs and 18 Tubes more -to mention it's also a synchronous detector for AM is not worth the effort. Panoramic display, digital frequency counter, Teletype Adaptor, a remote control for controlling that beast over a telephone line? FM? Diversity reception?? No problem, you had just buy it. Everything of course with the same standards for precision and build quality.

The outcome...

Yea, i spent a good amount of money getting this -but in my opinion it was worth every dime. I wanted a good tube receiver and i got a really good one. Compared to upper class modern Radios it's still a very good radio. So the only thing I have to add is an external SSB/AM-Synchronous Detector. The originals are nearly impossible to get today, so i decided to build one. It's on the way and i will give you the results later. So stay tuned...
