redis_mlc··on Americans Have No Idea What the Supply Chain Is
Detroit invented both the assembly line and also related mfg. process efficiency.

(In WW2, Detroit made weapons 3x or more cheaply than the Germans, who clung to individual craftsmanship. For example, if you watch period films, you can see Detroit machining several parts in parallel. They also redesigned all the sample parts provided by the military with cheaper materials and less parts or machining.)

Kaiser pioneered modular construction of ships in WW2, making a new Liberty cargo ship every few hours and a new aircraft carrier weekly (!), totalling 120 carriers by he end of the war. Britain thought he wouldn't even finish one. (His first shipyard was in SF Bay.)

Toyota adopted mfg. ideas from Deming, but obviously he influenced companies before then. Ironically, it was Detroit that got leap-frogged.

It should be interesting as Japanese companies move en masse from China to other countries in the region. The CCP is pushing them out to recover land, especially in port areas, and they blocked capital outflows in 2016, meaning foreign investment is a one-way trip.

redis_mlc··on 'Cottagecore' and the rise of the modern rural fantasy
I grew up in a farming area, and my family had a 30'x30' garden.

Farming is a lot of work. It's a job, not a hobby.

Even the garden was a fair amount of work, but more importantly, it's a lot of veggies to eat after harvest. I had tomato sandwiches daily for months. Plus insects to control. Doable, but not glamorous like the "cottagecore" photos.

If I did a serious garden again, I'd focus on becoming a skilled grower of certain veggie strains over a period of decades, and not focus on quantity.

Also, know your soil. If you're in an urban area (or downwind) that used to have steel or auto factories, then your soil is contaminated with heavy metals.

redis_mlc··on Five cops sue Tesla over “severe injuries” caused by car on Autopilot
> Most people do not know the technical details of airplane autopilot systems, because they are not technical nor are they pilots. Colloquially, autopilot means fully autonomous to most people.

That's not how they work or are used in aviation:

1) The pilot in command is solely responsible for the flight, not a device. That's why there's 2 pilots on airline flights, and will be for the forseeable future (ie. decades.)

2) Autopilots are either basic levellers (like automotive cruise control systems), or FMS (computer systems.) In either case, a pilot configures them, and is likely to deactivate or re-program them during flight. There's no confusion who is responsible though - solely the pilot in command.

3) The pilot is not there "for legal reasons" - he's there as the airman responsible and in control of the trip.

4) An airline might have minimum equipment lists (MELs) that require a functioning autopilot for revenue flights, but it depends on the aircraft model. (Because airliners are complex machines, it's not required to have every single piece of equipment working for each flight.)

redis_mlc··on Serious privacy/security concerns raised about Portpass vaccine verification app
In China, the vaccine testing data is already integrated into their social credit score system, so you can't get on public transit, etc. without completing the vaccine milestones.

In the US, the govt. has an internal system called XKeyScore that tracks your email, web and credit history.

In Australia, they have a "private" vaccine tracking app, but from Day One the police admitted having access to the database. (The police called reporters stupid for believing the app data was ever private.)

redis_mlc··on When CDs Launched in America (2016)
I was one of the first people in North America to create CDs, in 1984.

I was working with a scientist who had connections with Sony Japan, who had 6'-tall rackmount CD writers.

We would mail a 9-track tape to Tokyo with sample remote sensing data, and they'd mail back a CD. Although it didn't contribute to the scientific projects directly, we were able to demonstrate the new technology to various groups at a national lab.

Overall the feeling was that it was very cool to have that amount of data on a device that small.

I'd say the first pressed data CD I saw was the Microsoft Encarta (encyclopedia) CD around 1993:

https://en.wikipedia.org/wiki/Encarta

About a year or so later I was one of the first users of the Optimem 1 GB 12" optical drives. We used that to archive large amounts of software and experimental data. It was nice to be able to write your media incrementally. One small project was to copy the world's freeware (about 500 5.25" floyy disks) onto a single optical disk for users to find sample code and utilities.

I printed out an index on paper and distributed that to several programmers, and they would let me know what they needed.

redis_mlc··on Did a Chinese hack kill Nortel? (2020)
It's an interesting history lesson, but the problem with Huawei today is this:

They (and the CCP) will fund 100% of the rollout for a telecom to use their 5G server equipment. For Western mfgs. to compete, either Huawei has to be banned, or equivalent pricing and funding has to be instantly available. Or no sale.

Nortel never had a chance to compete with that.

The US funds Boeing's overseas sales via the Export-Import Bank, but that plan has to be extended to domestic and foreign 5G sales.

redis_mlc··on Definitive Account of the CIA/Media/BigTech Fraud
> We’re mad that the Bidens profited from coverups

In the area of $1 billion from the CCP and Ukraine, with Hunter flying with Joe Biden on official business to those countries. The US was literally for sale.

Also, the Clinton Foundation took over $2 billion from Saudi Arabia, which stopped when Hillary lost the Presidential run.

> the Trumps haven’t ever benefited from the same type of coverup?

No financial benefit when in office.

> Do people really think Trump became a billionaire by just being a sweet person?

He inherited around $1 billion from his father, a major NY real estate developer.

> Do people really think that Trump hasn’t ever used his influence to squash a story or report that he didn’t like?

Not for monetary benefit.

The major incentive for Trump to run as President was patriotism. The major incentive for his Dem. opponents was wokeism and Marxism.

redis_mlc··on China’s Evergrande veers toward collapse, unpaid debts spark protests
What's happening is this:

- China's recent economic growth was half due to real estate, a substantial part which was speculation

- the "real estate developers" usually just take the deposits and sometimes build a property, but often not (a ponzi scheme)

- it only takes a small amount of embezzlement, which is rife, for the house of cards to come down. Where's the money? In US and Canada Wsst Coast real estate, of course.

- this exposes the ponzi practice for most such companies

- which means China's real economic growth is somewhere between half to 2/3 of what has been reported for 2 decades

- this threatens investment in China as the story is adjusted down.

- in addition, China has stopped capital outflows since 2016, so foreign investment is one-way. (if you're Volkswagen and you invested in building a factory in China, you got played.)

redis_mlc··on The curious case of fake NASA geniuses
There was a recent in-depth thread on avweb about teen girls trying to fly around the world in small planes.

Besides the ones who have died (Dubroff, etc.), it turns out none had the training to reasonably attempt the flight.

https://en.wikipedia.org/wiki/Jessica_Dubroff

Besides the high risk to themselves, those flights involve SAR from various nations and often flow and landings at large airports with airliners, which those entities never asked to get involved with.

As an aside, the US Navy ended up searching for Amelia Earhart, so that shows the disruption of these flights.

redis_mlc··on Taking part in Y Combinator from Europe: is it worth it?
> They didn't acquire it because they thought their tech was great or that they had a great product.

Well, the actual fact is that Youtube was a great product with twice as many features as Google Videos as documented in the San Jose Mercury News diagrams published at the time. And growing faster.

So however Google discussed (underestimated) it at the time, Youtube was not only a credible product, but a better one, which was understood by Google, if unstated.

IOW, Google might have been arrogant about the difficulty of building a similar product, but that doesn't change reality that they didn't.

> They acquired it because a) the team was local and b) because sequoia invested in it.

That might be what the initial reasons were. But after Youtube won the eyeballs, Google paid a market rate for network effects and eyeballs to monetize at 1000x their initial valuation estimate.

Also, Sequoia's funding meant that Youtube would continue to grow exponentially and stay ahead of Google Videos. So it's true that SV VCs are incestuaous across boards, but their funding also in reality builds out competitors.

Similar situations are when Microsoft also chased Hotmail and Facebook as they climbed in value, far greater than MS' initial valuations and offers.

Ballmer actually tried to motivate Zuck by saying he could buy a private jet if he took MS' offer. It's one of the most Ballmer things I've ever heard. The second-most is when he said he'd stay on the board for a year but bought a sports team instead - taking his toys and going home.

redis_mlc··on An old programmer loses his job
1) That's not true. There's a narrative outside the field that it can be outsourced, even VCs have "sagely" told me that, but it's a lay person misunderstanding. (Ironically, very little semi hardware is done in US startups, so that leaves only software.)

2) US companies keep ratcheting up interview demands, which artificially constrains eligible candidates.

Examples are using coderpad where your code has to compile and pass a test/performance suite now, and doing random memory quizzes in addition to programming. But that's the fault of the hiring company.

redis_mlc··on Facebook bans German anti-lockdown accounts under new ‘social harm’ policy
> So, I'm asking whether, in this specific instance, people believe it to be the actual intent of the U.S. government to willfully and maliciously use COVID as a pretext for turning the U.S. into an authoritarian regime?

Yes, millions of Americans believe that.

It is also true that the Democratic Party is an authoritarian and corrupt government that is spreading corona throughout the US by opening the southern border to over 2 million illegal aliens in 2021, and allowing Afghanis to enter the US without corona testing or even a reason for admission. (The only quarantine restriction on Afghanis is if there's a measles case on the plane.)

Here's 10,500 illegals on Sept. 16 waiting under a Texas border bridge who likely have corona (the White House ordered the FAA to stop drone s from recording this because it's so horrific):

redis_mlc··on Ten Years of Fukushima Disinformation
> This is an excellent resource

No, it's trying to minimize the costs - it's a coverup.

- the cleanup cost will be around $1 trillion and require significant army and political involvement for decades. These are costs borne by the taxpayer. (The Japanese PM actually coordinated the response directly after the plant operators started to abandon the site in the middle of the crisis!)

- 250,000 area residents were evacuated to school gyms, etc. and many will die there

- the US govt. intervened to analyze the true risks with a drone, and notified the Japanese that if the cooling ponds evaporate, there will be a fire and airborne release. So that was another emergency that had to be remedied.

- the operator was notified of the risks of flooding years beforehand. To save money, they defied the recommendations.

Stop being a nuclear apologist when you're incapable of understanding the most basic issues at hand. Merkel, who I don't respect, is right in this case that if it can happen in Japan, then it can happen in Germany.

redis_mlc··on Where is the scrutiny over FDA’s role in the overdose epidemic?
> So clearly the government has been successful in this case.

It's hard to tell when side-effect reporting is suppressed.

Currently OSHA is banned from reporting on vaccine side-effects. That means the government wants no accountability, despite promoting employer mandates.

OSHA is also advising employers not to record side-effect data:

redis_mlc··on House Democrat's New Tax Plan Could Provide $2.9T in New Revenue – The Mountain
Your comment makes no sense outside of superficial Marxism, but I'll comment on one line:

> What I don't quite understand is why don't they just print a few more trillions?

To a certain point, as the USD is the global currency, we can do that. (And we did during the corona pandemic.)

After that point, printing money causes people to lose confidence (since it's just paper, and not money) and find another currency. Then you can't print any more without causing the currency to devalue.

This would be very bad for 2 reasons:

1) As the global currency, the US benefits by about 1% to our economy. You could argue this pays for our military expenditures.

2) We would have to make debt payments to support the currency. After a certain point, that becomes impossible.

FYI: the CCP is trying to replace the USD, and will exploit weaknesses in how we manage the USD.

Maybe you're young, but I can remember 20% inflation/stagflation back in the day. It was a very uncomfortable feeling for people to lose control of the value of their savings and prices for imports. You want to avoid that at almost any effort.

Pundits for decades have said that the fundamental weakness of democracy is that voters can vote themselves free money. This is what the Biden administration is actually doing now.

redis_mlc··on Phony diagnoses hide high rates of drugging at nursing homes
FYI: for people who don't know what's really going on.

The homes in the US are prescribing unnecessary medication for 3 reasons:

1) To bill for the medication and dose administration.

2) To bill for the skilled nursing staff.

3) To make the resients more docile, reducing caretaking costs.

These perverse economic incentives greatly impact the residents' health.

It's important, especially in the US, for all patients to have an advocate (asking questions and helping to make good decisions) mediating between the patient and provider. Ideally that's a family member.

Besides over-medication risks, there are also lawyers fleecing the elderly out of their assets. It's low-risk to the lawyers because elderly patients die, and what's the family going to do - sue a lawyer?

redis_mlc··on A Battery Spot Welder Made from an Old Microwave and Excessive Mahogany [video]
Fun fact: the cavity magnetron found in micraowaves was one of the most secret inventions of WW2, and guaranteed victory for the Allies.

It was invented to generate 10 cm waves in a compact package, which are ideal for radar. Although Germans and Japanese did early research on the magnetron, the Allies leap-frogged them.

The Americans had a university campus (around 4,000 staff) design production units for literally everything larger than a jeep that moved .

A Brit hand-delivered their prototype to the US, and the US solved some issues and productionized it.

Because the magnetron is made out of a block of metal, there was no way to destroy it after an airplane accident. But the Germans weren't able to adapt it, and admitted it was beyond their understanding at the time.

Ironically one of Germany's most advanced signals airplanes was captured just off a beach in England, but politicking between the navy and army meant it was left in seawater until it completely corroded. (You can identify these special signals planes by numerous antennae mounted on the nose.)

redis_mlc··on Ask HN: How to deal with loved ones that are affected by fake news?
ikr. Reading HN posts based on MSM fake news is "really difficult."

Examples of fake news repeated on HN:

- corona wasn't a lab leak

- Jan. 6 protesters killed 5 people (4 were natural causes, 1 was by Capitol police.)

- Marxism "is the majority" and gives you the right to cancel other people.

- masks prevent corona transmission (the most common masks are only 5% effective.)

So how do we prevent HN from repeating fake news?

redis_mlc··on Predictors of Nonseroconversion after SARS-CoV-2 Infection
In the first weeks of Corona's "official" entry to the US in 2020 (1), it was reported that sick people in the NY area had to pull strings or prove contact with a known patient or recent travel to an infected area to get tested when calling the official hotline.

So nobody who caught it on a train or in an office could confirm if they needed to quarantine, which actually happened.

If that person was later admitted to a hospital, it was game over for that hospital and any elderly people sent back to their nursing home.

1. The actual entry date was likely fall 2019 because of the Wuhan Military Games and airline travel from China to the US. SF never really had a hospitalization spike in 2020, so corona infection appears to have been spread out compared to other cities and was probably endemic in 2020.

redis_mlc··on The Unsolved Mystery of the D-Day Puzzles
That's correct. You can think of the Normandy invasions as succeeding in slow-motion. Planners were hoping for results on D-Day, but it took 10x to 100x longer than expected to achieve each objective.

Caen (port area up to 9 miles from the beach) was a D-Day objective, but depending on the area took 1 month to 3 months to capture. The Allies were slow, and the Germans knew it was a strategic location. Regardless, it just meant that the German army was destroyed around Caen, instead of elsewhere.

https://en.wikipedia.org/wiki/Battle_for_Caen

Of the 5 landing sites, Omaha Beach was the bloodiest, with Americans wading ashore into machine gun fire, killing around 2,000 Americans.

(In Italy and Holland, Americans were also mowed down as the Germans retreated.)

The most famous disastrous amphibian landings were Galipoli in WW1, where the British failed to break out of their beach heads, and also lost numerous ships to mines and shore batteries. This tarnished Winston Churchill's reputation for decades. The victory by Turkey led to its rise as a modern state.

And the US struggled with 3 landings (Anzio, etc.) in Italy in WW2 due to General Clark and his staff trying to consolidate beach heads before breaking out, allowing Germans to occupy high ground, after the landings!

https://en.wikipedia.org/wiki/Battle_of_Anzio#Breakout

Literally, the Americans would loiter on the sand instead of sending a dozen troops to secure roads and hills before the Germans arrived with artillery.

The US had phenomenal leaders in the Pacific War, but Italy was a total failure in multiple dimensions. Historians today just laugh at our role in Italy - it was that bad.

(The British had the weird problem that upon reaching the beach, soldiers would sit down and start making tea, even under fire.)
