> It makes sense to me that moving from electric to piston would require an endorsement.

For a long time, it will be the reverse; the default will be a requirement to be able to fly a conventional-engined airplane, with electric propulsion being an endorsement (probably devoted primarily to battery & power management)

> It would make some sense as mis-managing the fuel-air mixture on a small piston plane can lead to catastrophic failure. (frozen carb for ex)

Carb freezing doesn't occur as a result of mixture mismanagement, but rather by failure to apply carburetor heat when flying in conditions conducive to carb icing.

Mismanaging the mixture is far less likely to have any acute effects. Descending with a lean[er] mixture may cause issues at lower altitudes where the mixture would be too lean, but it would be unusual for that to lead to an engine stoppage.

Further - a pilot inexperienced in mixture management would likely not lean the mixture at all and just fly full-rich which again, wouldn't likely lead to any acute failures, just higher fuel consumption and longer-term issues with the engine.

> still radial engines due to the nostalgia that sells to tourists

Given the relatively thin margins in aviation, I think it's probably less about nostalgia and more about the $1M USD price of e.g. a PT-6 turbine

Unless you know of some secret section in the tax code, it's not a "2 for 1 deal" - if Bill Gates donates a billion dollars to a charity, it makes sense that it wouldn't be taxable; it's no longer his money. Typically the tax code reduces your income by money for which you don't actually have constructive use.

There are certainly other things like 'in-kind' donations which may reduce tax obligations without necessarily providing a commensurate value, but putting money into bona fide charitable works are not among them.

This is biology-dependent. With CRTs, I could detect flicker all the way up to 85Hz* (where it vanished for me). Made it a real pain to find a good monitor.

* Hitachi 21" CRT which seemed enormous at the time

The 787 also pressurizes the cabin to a lower altitude. Most aircraft pressurize to an altitude of 8,000 ft (~2,438m). The 787 pressurizes to 6,000 feet (~1,828m), which is a noticeable difference - it's like being in Denver vs. higher up on a mountain. Your blood oxygen concentrations will be higher as a result.

The article states (and I have heard this independently) that the Boeing 787 is the only aircraft which does not use engine bleed air to provide air to the pressurization and air conditioning system.

> The beauty of inflation is that it hurts you in direct proportion to how well off you are

This seems opposite of reality. During inflation, prices of assets rise, as the currency with which to procure them becomes devalued; those who possess assets are in a much safer position than those who exchange their labor for currency, since inflation will happen far more rapidly to the necessities of life (food, shelter, etc.) than to wages.

Cf. the price of houses, cars, etc., in the U.S. and worldwide vs. the corresponding increases in wages.

From a marketing standpoint it doesn't make sense to update the design (this is typical Apple from what I've observed) - People will buy into the novelty of the new CPUs. For the refresh, you will probably see some design changes.

Even though it's not included (and supplies are incredibly constrained right now for new ones) a standard USB webcam can work. Logically it doesn't really make sense to include a built-in webcam for a keyboard form factor. Adding an external one doesn't make sense in terms of meeting their pricing goals.

Doubtless one of the resellers will augment this with a package that includes an inexpensive USB webcam.

This is an unacceptable use of customers' information (email). It would be equally unacceptable if he was urging a vote for Trump.

This type of politicization of communication channels is an unnecessary imposition on customers and an abuse of trust.

If they feel compelled to continue this, there should be a checkbox in preferences "I consent to being sent political information"

That’s not really how credit reports work. At least in the U.S. a loan typically doesn’t report until the first statement period usually 30-60 days after loan issuance. Most likely it would just show as a paid loan after you returned the car.

I think this a lovely sentiment, but (1) would never get past HR - what do you do with that $30K for a renter? How do you ensure parity between upgrading a high-rise condo in NYC vs. a simple ranch-style house in Kansas? Like a bonus, is the employee on the hook for paying back the $30K if they leave within a few months or a year? What if the employee wants to / has to move? Do you get another $30K if you move within 1 year? 2? 5? Ever?

> Corporate travel will never return to pre-covid levels, and credit card miles are a big part of this as well.

One example - The last several years, I probably charged in excess of $120k / year on one particular airline card. This year, probably $1000 so far, mainly recurring bills I haven't bothered to switch to another card.

Since cards had become a significant revenue driver for airlines, this is going to have some medium term negative financial consequences as well.

(I'm probably not even in the top 20% of business travelers, either)

I've noticed the same thing on EC2 instances, compiling, e.g. Alacritty, there wasn't a lot of difference between 8 vs 16 vCPUs since the last step took a significant portion of time and was single-threaded. It's fun watching 16 (or 32) CPUs maxed out though.

In the parent article, the author talks about obtaining replacement bulbs - Since this is an arc lamp, there's no filament to burn out.

Does anyone know the failure modes of an arc lamp? Do the electrodes wear out / erode? Is repair even possible for something like this or is it essentially remanufacturing the entire thing because of the capsule enclosing everything?

I understand what you're saying but I disagree that it can be reduced to 'buy the right glue' and 'make sure it gets put on correctly' any more it does any more justice to a model CPU to say it's just 'take a transistor and replicate it 5 billion times on a hunk of silicon'. While that's technically true in both cases, it neglects to consider the level of technology that goes into all of the details to make it possible.

I'm not saying that attaching glass to metal is at the same level of complexity as semiconductor fab, but it's a far cry from using some Elmer's Glue to stick two pieces of construction paper together.

And yes, I'm pretty sure Tesla didn't create their own adhesive for the purpose, but I'm equally sure 3M doesn't have an off-the-shelf "Model Y Roof Adhesive, 500ml" product. Or perhaps they did, but the engineering constraints to develop it were those of normal passenger cars, sunroofs, etc., not taking into account the various forces acting upon a 4'x7' sheet of glass at highway speeds, or perhaps the temperatures or speeds of an industrial applicator robot (or conversely, the slowness of a human applicator).

To go back to your original assertion, no, it's not hard to lay down a bead of adhesive, place the glass in and check that it's been done. If in fact the failure mode was 'Failure to apply adhesive', well, that's a fairly egregious and easy to spot problem. If it's 'adhesive failed for unknown reasons after a short period of time', that's an altogether different problem.

> Do people really think that "gluing the glass in" is some bit of advanced engineering?

Conversely, do _you_ really think that - evenly applying an adhesive to an incredibly smooth surface (repeatably) to bond it to a frame and have it undergo twisting, vibration, and extremes of heat and cold, aerodynamic effects / pressure, exposure to moisture, UV and atmospheric contaminants and retaining its adhesion for the expected life of the vehicle -

isn't advanced engineering?

> commuting has significant mental-health benefits

This seems like a stretch for anyone who has ever dealt with rush-hour traffic in a major city.

It would be challenging to adapt in current circumstances with diesel-powered tractors, but electrically-powered tractors might be able to make use of electromagnetic couplings (at least to get the process initiated). You might be on to something for future use.

Good luck with the new attempt. It seems like you're well-armored for the task. Go forth and conquer!

Supposing you could adapt the ROM/EFI/SMC to work with the new motherboard. (I'm not claiming practicality here, just possibility), perhaps desoldering & resoldering the respective chips onto a new daughterboard or even a PCI card.

Does that make it a Mac still? You could literally replace almost every component in a Mac except for the motherboard and have it still be a Mac, but shouldn't the converse be true as well? If I used the original case, hard drive/SSD, video card, keyboard & mouse, even the CPU, but replaced just the logic board (swapping the ROM/EFI/SMC somehow), it seems to me it would still be considered a Mac. Particularly if in the process the original logic board was rendered inoperative to head off any claims of duplicate license use.

No, it's not related to Darling, but it did provoke the question for me of whether it is [legally] possible to 'upgrade' an original Mac to modern components and still have it be considered a Mac. Clearly a hard drive, ram replacement, and video card replacement are acceptable, CPU if it happens to be replaceable, keyboard, mouse, monitor. Really the only thing that might remain is the motherboard. But if you kept that and replaced anything else, shouldn't that could as still being a Mac?

You’re welcome! It sounds like you had a frustrating day. I’ve definitely been there and have the stories also. I hope your next attempt goes more smoothly.

I just got a quick hitch myself recently and it’s like magic! The only downside is that I couldn’t find one that worked with my mower as well as the other implements. I think I can fabricate a mount for the mower to work.

Good luck!

This is somewhat a philosophical question/ Ship of Theseus - you are only licensed to run MacOS on Apple hardware, but what if I had, say, an Xserve and replaced a hard drive? What about a Motherboard? Would a Franken-XServe with an AMD Threadripper still be ‘Apple Hardware?’

I have a theory that for women, it's really the middle ground that is hardest; small light things are easy enough for anyone, and very heavy things level the playing field also; nobody, man or woman is going to lift something that weighs 500 lbs., so you use pulleys and winches and hydraulics to make life easier. But the middle ground is tough because you might have to lift something 150-200+ pounds which will exclude most women and a number of men, but may still be light enough to not normally demand assistive machinery.

In any case, I've had my challenges with PTO shafts on a Kubota + Land Pride mower. The other comment about greasing the PTO shaft & coupler is probably a good start.

I found the biggest challenge to be holding down the retaining ring(?) while simultaneously rotating and pushing the PTO shaft onto the PTO. I don't know about the layout of your spader, but anything to help take the weight off so you can just worry about the alignment part will probably help.

I believe it is the author of the Python Requests library, and I believe this is the logo in question: https://upload.wikimedia.org/wikipedia/commons/a/aa/Requests...

This reminds me of fun times compiling and upgrading libc on a running system. It's challenging, but if you plan it out, it's not bad. But if you miss a step...better hope you have some statically compiled tools somewhere that can help you out.

Exceeding 10,000 ft. is orthogonal to needing anti-/de-ice systems. In fact, you're often less likely to need them at the higher altitudes because it is too cold for airframe icing to occur. Counterintuitively, if it is too cold, you no longer have icing problems.

It could be unrelated to a prior jailreak - I had installed the iOS 14 Beta and my banking software insisted my phone had been jailbroken. Fortunately it allowed me to 'Accept the risk' and continue.

I think the most likely scenario is that there is a third party library or service to detect jailbreaks and it is faulty.
