When I was a young kiddo, up through high school, I had two passions: biology and airplanes. You can guess which one won out, but I still sometimes dream of flying. In those days, I’d bicycle out to one of the local airports — Boeing towns had no shortage of them — and just hang out at the chain link fence by the end of the runway, or bike around the hangars. It was a treat to take a long bike trip to the Museum of Flight, which at the time was a big hangar where people were reconstructing a biplane, but has since expanded into a magnificent complex with all kinds of planes.

I am suddenly reminiscing about this because YouTube randomly served up a video about one of my favorite old-timey airplanes, the P-26 Peashooter.

That great big radial engine, that lovely post-war color scheme, and it’s wearing pants! Before retractable landing gear became a must-have for any high performance plane, they were outfitted with aerodynamic coverings, which I find irresistibly charming. Planes from the 1930s hit a sweet spot for me, so this random video in which nothing really happens was something I had to watch. It’s an odd trigger that reminds me of being 15 years old again.

So why did I give up my fascination with planes? One factor was that I only learned in high school that I was extremely near-sighted, and needed glasses — that felt like discovering that I was broken, and nature was telling me that certain pathways were closed to me. I was also getting deeper and deeper into that scholarly stuff, reading constantly, which probably contributed to my optical failures. I still sometimes think it would be awesome to take flying lessons, except a) no time, b) no money, and c) age has taught me that there are many things that look easy, but actually require a great deal of skill and discipline to do well. Flying is one of those things that is unforgiving of dilettantes.

But still, those aircraft from the Amelia Earhart era give me a little tingle.

Everett, Seattle, Renton, Kent, Auburn — growing up in the Seattle area, we knew the chain of Boeing towns, where so many of our family members worked. My father worked in several of those plants as a diesel mechanic, my mother was wiring the planes, my brother works in the windtunnel unit, my sister was in marketing — we had a lot of Boeing pride. Before about 1990, when booking flights, I’d actually preferentially select Boeing planes over Airbus, because it was reassuring to be on a plane where I could imagine my Mom building cable assemblies with loving care.

No more, of course. Boeing, a company of engineers, merged with McDonnell-Douglas, a company run by profit-seeking military contractors, and oh boy, those flightless chickens have come home to roost, where “home” is no longer a series of factories but skyscrapers in Chicago. They got the John Oliver treatment this week.

I wouldn’t fly in a Boeing MAX plane myself. I’m just a timid little biologist, though…it’s a bad sign when your own former engineers refuse to fly in them. Ed Pierson, ex-Boeing engineer, says:

Last year, I was flying from Seattle to New York, and I purposely scheduled myself on a non-MAX airplane. I went to the gate. I walked in, sat down and looked straight ahead, and lo and behold, there was a 737-8/737-9 safety card. So I got up and I walked off. The flight attendant didn’t want me to get off the plane. And I’m not trying to cause a scene. I just want to get off this plane, and I just don’t think it’s safe. I said I purposely scheduled myself not to fly [on a MAX].

Our recommendation from the foundation is that these planes get grounded — period. Get grounded and inspected and then, depending on what they find, get fixed.

The people to blame are the executives at Boeing.

Boeing’s board of directors — they have a fiduciary responsibility to make sure that their products are safe, and they’re not in touch. They’re not engaged. They don’t visit the sites. They don’t talk to the employees. They’re not on the ground floor. Look, these individuals are making millions of dollars, right? And there’s others between the C-suite and the people on the factory line. There’s hundreds of executives who are also very well compensated and managers that should be doing a lot more. But their leadership is a mess. The leadership sets the whole tone for any organization. Public pressure needs to continue.

That board of directors, and all those executives, don’t know what they’re doing. They ought to all be fired, and the company put in the hands of good engineers who prioritize safety and quality, but instead you’ve got accountants who just want to make lots of money, doing their “fiduciary duty.” Ironically, all that short term emphasis on profit is destroying the company, trashing their reputation, and killing people. I also wouldn’t invest in Boeing any more.

Hey, why are stock buybacks even legal? The executives seem to be more interested in artificially pumping up their stock prices than in, you know, building airplanes.

Oh well. It’s all great news for Airbus.

Can we just knock it off with the AI nonsense? Somebody is profiting off this colossal sinkhole of useless frippery, but I don’t know who. Look what it’s doing to our environment, all because people like Mark Zuckerberg have decided it’s cool, and the future of profiteering.

The amount of water that A.I. uses is unconscionable, particularly given that so many of its data centers are in desert regions that can ill afford to squander it. A.I. uses this much water because of the computing power it requires, which necessitates chilled water to cool down equipment—some of which then evaporates in the cooling process, meaning that it cannot be reused. The Financial Times recently reported academic projections showing that A.I. demand may use about half the amount of water consumed by the United Kingdom in a year. Around the world, communities are rightly beginning to resist the construction of new data centers for this reason.

Then there’s A.I.’s energy use, which could double by 2026, according to a January report by the International Energy Association. That’s the equivalent of adding a new heavily industrialized country, like Sweden or Germany, to the planet.

Microsoft’s own environmental reports reveal these immense problems: As the company has built more platforms for generative A.I., its resource consumption has skyrocketed. In 2022, the company’s use of both water and electricity increased by one-third, its largest uptick ever.

We should be asking what we gain from glossy shiny artificial artwork, or from bizarre texts cobbled together by machines that don’t actually understand anything. Search engines are already corrupted by commercialized algorithms, do we really need to add another complex layer that adds nothing to anything? Tell me one thing AI adds to improve the world.

Do we need this?

Dozens of fake, artificial intelligence-generated photos showing Donald Trump with Black people are being spread by his supporters, according to a new investigation.

BBC Panorama reported that the images appear to be created by supporters themselves. There is no evidence tying the photos to Trump’s campaign.

One photo was created by the Florida-based conservative radio show host Mark Kaye.

“I’m not out there taking pictures of what’s really happening. I’m a storyteller,” Kaye told BBC. “I’m not claiming it is accurate. I’m not saying, ‘Hey, look, Donald Trump was at this party with all of these African American voters. Look how much they love him.’”

Maybe what we really need is a Butlerian Jihad.

This is mildly interesting: scientists have modified muscle cells in culture so that they produce their own growth factors. This is a major cost reduction, because now you won’t need to constantly supplement your vat of muscle cells with a relatively expensive reagent.

Cellular agriculture – the production of meat from cells grown in bioreactors rather than harvested from farm animals – is taking leaps in technology that are making it a more viable option for the food industry. One such leap has now been made at the Tufts University Center for Cellular Agriculture (TUCCA), led by David Kaplan, Stern Family Professor of Engineering, in which researchers have created bovine (beef) muscle cells that produce their own growth factors, a step that can significantly cut costs of production.

Growth factors, whether used in laboratory experiments or for cultivated meat, bind to receptors on the cell surface and provide a signal for cells to grow and differentiate into mature cells of different types. In this study published in the journal Cell Reports Sustainability, researchers modified stem cells to produce their own fibroblast growth factor (FGF) which triggers the growth of skeletal muscle cells – the kind one finds in a steak or hamburger.

Keep in mind that this works for cultured meat cells, which is completely different from the artificial meat made from plants that you can buy in stores right now. I have a few reservations about it.

This is basically a tool to remove a regulatory limit on muscle growth. When this happens in vivo, we call it cancer. I suspect the marketing department will balk at labeling it “tumor meat”.

The technique amplifies one cell type. Edible meat has texture and is made up of a mix of cell types, fat and connective tissue. This is a way to make large quantities of something that is equivalent to ‘pink slime’ or, as the marketers call it, ‘lean finely textured beef.’ We already do this! I guess it’s a good thing to be able to produce large quantities of protein in the form of ‘pink slime’ more cheaply, and without the need to slaughter animals to do it.

Without a regulatory limit on growth, though, don’t be surprised if a news headline later announces that Boston has been eaten by a giant ever-growing blob of immortal meat.

The only reason to visit Las Vegas is for the exotic spectacles (don’t gamble, it’s a scam) and Elon Musk may have added another one.

Despite a decade of dreaming, Elon Musk has only built one tiny Hyperloop tunnel in Las Vegas — and the people who built it say it’s filled with dangerous chemical sludge.

As Bloomberg reports, the Boring Company’s scarce output — which thus far amounts only to driving Teslas around a few miles of neon-lit tunnel underneath Sin City as they ferry convention attendees at no more than 40 miles per hour — has also come with a massive buildup of waste, the consistency of a milkshake, that’s said to burn the skin of anyone who comes in contact with it.

In interviews with the news source, Boring Company workers who declined to give their names on the record for fear of retribution said that in some parts of Musk’s Vegas tunnel system, the sludge would sometimes be up to two feet high. If it got over their work boots or onto their faces, they said, it would burn their skin.

The article doesn’t say where the toxic sludge is coming from, which makes me wonder what is leaking. The Daily Mail — not a reliable source at all — is reporting that the sludge is made of chemical accelerants, and that the worker’s complaints were made while the tunnel was under construction.

It was a crap project anyway, and a poor solution to transit problems, so shut it down already. Hyperloop One, Virgin’s project, has already been declared dead. I hope somebody in Minnesota is paying attention to the news, and is ready to kill the Minnesota hyperloop project.

Once the Boring Tunnel nonsense is shut down, we can get back to the serious business of mocking Elon Musk’s Flaming Vehicles of Fiery Death.

Two men were left in serious condition after the Tesla they were traveling in went off an overpass and burst into flames on the 134 Freeway in the Griffith Park neighborhood of Los Angeles Sunday night.

See, it’s like a metaphor for Musk’s career and an entertaining fireworks display in one! (the occupants of the car survived, fortunately. Let’s not have the spectacle of drivers on fire or tunnel workers melting.)

Some people in Minnesota have a dream to make a popular commute easier — the hour and a half drive from the Big City of Minneapolis to the Major Medical Hub of Rochester, where the Mayo Clinic is located. These dreamers want a whole bunch of money to research a proposal to build a…hyperloop.

Hyperloop? Are they kidding us?

Hyperloop is a fantasy built up by Elon Musk that has never been implemented successfully, and when tried, simply sucks up a huge amount of money for transportation infrastructure to kill more practical ideas for mass transit. People are still considering it?

…group of high-profile backers is seeking millions in funding from the Metropolitan Council to help get the proposed project up and running.

The largely theoretical rail technology, known as hyperloop, was popularized in 2013 when billionaire Elon Musk published a white paper on the subject. Though some have expressed skepticism over the mogul’s seriousness about Hyperloop, there are active efforts around the world and in the U.S. to see it come to fruition — and Minnesota is the latest proposed site for such a system.

A nonprofit called Global Wellness Connections — whose board members include the mayors of Edina and Plymouth as well as former Secretary of State Mark Ritchie — is asking the Met Council’s Transportation Advisory Board for “most of the $2.5 million” needed for a feasibility study of a Minneapolis-Rochester hyperloop.

It’s dead, Jim.

Today, no full-scale hyperloops exist anywhere in the world. Musk’s test tunnel in California is gone. The man himself has become more enamored with endorsing antisemitic theories than solving the problem of car traffic.

The Boring Company, Musk’s tunneling operation, is still digging underground passageways in Las Vegas — but for Teslas, not hyperloops. The future, it would seem, is nearly the same as the present.

They want $2.5 million for a “feasibility study”. I’ll do it for a mere million dollars! Here’s the report I’ll send: “No, it’s not feasible, and has failed everywhere. How about building a regular commuter train?”

That thing to the right is a USB-C charger, a totally mundane device that we tend to take for granted. You’ve probably got one, or something similar. I have a similar device by a different company, it’s a boring utilitarian widget you need to keep a device powered up.

It contains a 48mHz CPU, 8K RAM, and 128K of flash memory. I’m torn between sneering at those pathetic stats and being impressed that a mere charger has that much computing power — my first home computer had a 1mHz CPU and 16K RAM, and heck, now mere cables contain complex circuitry.

But now compare that USB charger to the Apollo 11 guidance computer.

Compared with the Apollo 11 Guidance Computer it runs at ~48 times the clock speed with 1.8x the program space.

They compared several USB chargers to the Apollo guidance computer.

I guess once I dismantle this here stupid $30 wall charger, all I need to do is assemble a few million kilograms of simple stuff like rocket engines and fuel and a life support system, and I’ll be taking off for the moon. See you all later!
