There is at least one commercial EV aircraft that can do it, but frankly it won't be as big a deal as it is with cars. Cars are speeding up and slowing down all the time. Aircraft generally speed up, stay fast, and then slow down at the very end of the flight. And for most aircraft, the entire flight is powered from takeoff to landing. It could be useful in emergency situations where the pilot is at risk of overshooting the runway.

For aerobatic aircraft it could be a big deal. High power motors and the desire to be as light as possible will probably drive power recovery and even crazier stunts at airshows.

With a PC-12 you'll burn around $300 per engine hour in fuel alone, hot section inspections will come up every 1750 hours or so and cost $50k each, the engine overhauls will come up every 3500 hours and cost $350k

I wouldn't be shocked if replacing the electric motor costs less than what a turboprop inspection would.
But why would they ban short hops for highly efficient electric aircraft?
Don’t forget labor. You need to find talent to manage your little data center. And deal with it when it shits the bed at 4:12am on Christmas morning.

So toss in at least one SRE type person. Say $200k/year.

Since you only have one, they are gonna be on call 24/7, so assume you’ll burn them out after a year and a half and need to hire a new one....

Since redundancy is a thing, double that $350k. And 10pb is what they have now so double it again for 20pb. Add in $10k per rack for switches, routers, wires, etc.

So probably you are looking at a million dollars of capital plus labor to actually execute on this. And don’t forget the lead time might be a month to get the hardware and a week or two to install it. Plus all the configuration management that needs to be built up. Not to mention monitoring. So maybe a quarter of work just to have it functional.

I haven’t even factored in opportunity costs. What could this business be doing that adds more value than building out a little data center?

I dunno. Maybe it does make sense to manage your own hardware. But it helps to calculate the entire cost of ownership, not just the cost of the servers.

Prudhoe is a massive oilfield. It's thousands of wells spread covering an area around 200k acres. Every well pad and facility has lighting.

It’s not sloppy reasoning. We should update our beliefs in light of new evidence in proportion to the strength of the evidence and the strength of our prior belief. How much would an equivalent study on the existence of ESP move your belief on that subject? A good answer would be not much if at all because a priori we expect the study being wrong is far more likely than the existence of ESP. For me, it would take more than an observational study to update my belief at all. This is prioritizing anecdotes over data - moreover, my belief (ESP doesn’t exist) wasn’t scientific in the first place!

Epistemology is impossibly hard. Determining the strength of evidence is hard. In the places that a paper contradicts our mental model of the world, the only sane approach is to question the paper.

That's right. You can't prevent a mineral rights holder from accessing their resources - even if you hold the surface rights. The company developing the minerals has to compensate the surface owner for roads/pads/etc.

> Also, the stupid polar orbit around the moon isn't necessary if you have moon starlink (no comm loss on dark side). This saves energy otherwise needed for inclination changes.

What? Gateway is planned to be in a Halo orbit at L1. Getting to the lunar poles is actually cheaper from L1 than directly getting there Apollo style, and the poles are of interest for exploration due to areas of permanent sunlight (for power) and permanent shade (for potential ice).

Moon starlink? For comms you just need one or two satellites at L2. The Chinese already have one there. And it's not the dark side, it's the far side.

All EVs on the market can have their packs replaced. For old Nissan Leafs, the price of a refurbished pack has gone down to the point where it even makes sense to extend their lives with a pack refurbishment.
Thinking of this reply for a bit. From "How to survive a pandemic" by Dr. Greger, I recall this being an avian flu. So it's possible for covid to bounce around in them. Quick search, I'm seeing articles about even newer coronaviruses being discovered in birds. I don't think the wild population is the threat to most worry about creating future variants of covid. The biggest threat is probably where there are the biggest populations of birds in close quarters with one another and humans - on farms. Given how mink farms were recently slaughtered to stop the spread of covid amongst them, similar measures would be taken with poultry.

Avian viruses on farms have always been a big concern among the epidemiologists, if Dr Greger's book is any indication. Stopping the virus movements among humans and similar mass slaughterings among livestock could work. I takeaway that it's a statistics problem as to when and not if we see another virus capable of becoming a serious pandemic again.

The extent to which society learned how to monitor and react to new viruses during the covid-19 pandemic may well determine our fates next time.
I wonder if Apple's strategy is to push macOS developers to optimize for certain SOC cadences, rather than having to traditionally target every system configuration possible. Therefore they opted to only have limited SKUs of the M1: only differentiated by RAM and GPU cores.

Analogy is gaming consoles - the hardware is fixed for X years so game developers know exactly what to target and make better looking & performing games over the cycle of that console. Compared to, say, Windows 10 that has to run on an almost infinite number of hardware configurations.

This is actually similar to their approach to iOS and iPhones - iOS versions span across multiple iPhone cycles, but they are limits. For example, iOS 13 was supported on iPhones 6S thru iPhone 11, or the A9 thru the A13 SOCs. There's probably some correlation between good performance and the tight SOC-to-OS coupling.

We'll likely see similar, limited configurations for future Apple M* SOCs.

Isn't altitude ultimately a function of energy? If you're decreasing altitude wouldn't that be a decent amount of recovery?

Gas turbines need to keep running to sustain combustion but electric motors can start and stop instantly with current flow; it seems possible to use this as part of the dynamic control of the aircraft.

Worth noting orbital refueling may not actually be that difficult, it was strongly rumored that Senate Launch System backers put the kibosh on refueling because it would jeopardize the SLS jobs program if it worked:

"We had released a series of papers showing how a depot/refueling architecture would enable a human exploration program using existing (at the time) commercial rockets," Sowers tweeted on Wednesday. "Boeing became furious and tried to get me fired. Kudos to my CEO for protecting me. But we were banned from even saying the 'd' word out loud. Sad part is that ULA did a lot of pathfinding work in that area and could have owned the refueling/depot market, enriching Boeing (and Lockheed) in the process. But it was shut down because it threatened SLS."

Just keep in mind that scaling things will change power efficiency. Like the Vega gpu architecture showed so clearly - which could be quite power efficient, but the Vega graphics card released were ridiculously power hungry, it seems because they missed their performance target and thus got overclocked out of their power efficiency range.

I'm not sure that they can easily add more cores to the M1. If they can, that would also raise the TDP. And adding more cores does not increase performance linearly, even if the architecture is made for it.

Also keep in mind that comparing it to 14nm Intel processors with an architecture from a decade ago is a fair comparison when comparing M1 vs prior Apple products, but is not a fair comparison when comparing it against what x86 can do in general. You would need a modern x86 processor targeting the same watt usage to have a completely valid comparison. As discussed in the thread above.

So yeah, it's a great processor for its target. And it likely will also be a very strong processor when scaled up - it bodes well for the future of ARM. But don't extrapolate the performance too linearly, that is likely to be misleading.
Actually, why don't planes cycle climbing to a height, switch off the engines, glide for X miles, restart engines to climb, etc ...

Pretty sure I used to do that when I used to fly in my Microprose F-15 and was short on fuel.
Electric planes don't really need much breaking, except when coming in for a landing.

At that point, your flight is over and you don't need any extra range.
This seems dubious. Even auxiliary costs of the average plane rental (hangar, insurance) can exceed that rate depending on utilization.

I think Jira is flexible on a different axis than what I was trying to convey.

I want it to be flexible to the end user. Jira is about flexibility in how you restrict the end user.

I think this means that it won't require much flexibility as the users can do a lot of what they want, leaving teams to organize themselves with the workflows that work for them.
True. Right now I could only buy an RTX 3090 for 3100 EUR (~3740 USD) and I am not willing to pay that much.

But I am happy to wait. Upgrading my gaming machine is a very low prio.
Chrome has a lot of processes, but only 1 or 2 processes do all the disk and network IO, so I don't think that particular hypothesis holds up.

What you say probably is an issue with CPU scheduling though.
That was exactly my point. The guy was saying people shouldn't correct an "incorrect" thing which is in common usage, but I was trying to emphasise that it isn't common usage everywhere.

This reminds me of when the iPhone first came out. Back then, most phones from other manufacturers had an assortment of random names and model numbers that carried no hint as to which one was better or newer. Meanwhile, iPhone N+1 was obviously better than iPhone N.

Samsung quickly learned to play the same trick with their yearly Galaxy S and Galaxy Note releases. That decision probably contributed to the market share they've been enjoying.
Is your argument that marginal cases would go to trial?

I think it is the case that marginal cases would take a no-jail plea bargain. Going to trial on a marginal case with a public defender probably increases the risk of imprisonment versus taking a guilty plea that guarantees no jail time (but a criminal record).
I doubt it's possible to try a AAA dev setup on OSX at all, and, for whatever it's worth 64G workstations were "hand-me-downs" at my previous gig (AAA gamedev), I doubt there's much magic that can make "64 gig is not nearly enough" go to "16G is fine"

I go for the man page first, then to a book on the language, then to the web. I work with many people (who are by far my senior) who never never check man pages and never search the web but go around bugging others for very simple things. Just this week I was asked how to find and replace text in a document and told to email them instructions.

This can be rephrased more generally: Effectively utilizing available sources of information is one of the most important skills for every engineer.
Is there a good article around that explains the specific semiconductor bottlenecks everyone is facing right now? I’d like to know more. It seems like a huge opportunity, but also I am guessing it’s a very hard or impossible problem since it hasn’t already been solved by infinite money?
Right, but that's why it takes a bit skill on the part of the examiner - you need to be able to support people through their nerves and lack of confidence.
I just explained above there's no single M1. They vary by core count, and by clockrate. And probably more.

The only thing that's "one" about M1 is the brand. It's one brand. It's easy to have a clean brand, when you don't sell naked CPUs by themselves. "Oh everything we have has M1". It doesn't even matter if this is accurate or not, we realize that, right?

Are we going to hold up Intel for having hundreds of SKUs because they sell chips alone, and Apple sells them in computers? I hope not, that'd be silly.

Are we also going to hold up Intel for being in the PC CPU business for decades, while Apple has been at it for several months only? I hope not, that'd also be silly.

Finally, are we going to hold up Intel for targeting cheap office machines, and high-end data centers, and hardcore gamers, and scientific uses, and many other customers that Apple isn't even trying to have? I hope not, same reason. :-)
I can't believe that I'm understanding this correctly? Just to be sure: NASA's plan is to fly the insanely expensive hasn't even launched into space yet SLS, onto some non-existing docking station, then SpaceX fly to the moon. Repeat back (does Starship have to dock again why can't it just go straight back into earth)?

While Starship can go to from earth to moon with a refueling stop alone? Even if sticking to the space dock why not the WAYYYY cheaper Dragon which just worked today (using a recycled rocket)?
I was going to say, I'm on a 16gb 2015 macbook pro (not sure what to upgrade to) and Docker for Mac is _brutal_ on my machine, I can't even run it and work on other things at the same time without frustration
Yes, I am saying the fact that someone can take your keys and you have zero recourse to ever reclaiming that value is a bug. It's one of the "original sins" if you will. Because that's not what anyone actually wants. I've never met anyone who was thrilled by the prospect that if anything went wrong nobody could help them.
Don't forget politics. As traditional religion has retreated Politics has taken on a greater role - politics as tribal identity. Good article here: https://www.theatlantic.com/magazine/archive/2021/04/america...

"The notion that all deeply felt conviction is sublimated religion is not new. Abraham Kuyper, a theologian who served as the prime minister of the Netherlands at the dawn of the 20th century, when the nation was in the early throes of secularization, argued that all strongly held ideologies were effectively faith-based, and that no human being could survive long without some ultimate loyalty. If that loyalty didn’t derive from traditional religion, it would find expression through secular commitments, such as nationalism, socialism, or liberalism. The political theorist Samuel Goldman calls this “the law of the conservation of religion”: In any given society, there is a relatively constant and finite supply of religious conviction. What varies is how and where it is expressed."
> Poole lasted just five years at Google, which CNBC notes is usually just long enough for any employee's shares attached to hiring to vest

They make it sound like he barely managed to get any stock. That's like saying, "person worked at X for 1 year, just long enough to get 1 year's salary." Well, yeah, but if they left in 11 months they'd get 11 months salary. It's not like if Poole left at 1 year or 4 years or anything in between he would have left with anything different proportionally to his tenure.

What an odd article.

While switching to LEDs can improve naked eye view of night sky, it sometimes negatively impact amateur astrophotography as mercury and especially sodium lamps have narrow emission spectrum and it can be filtered off using optical bandpass filters. LEDs light have much wider spectrum and cannot be filtered off.
Try using Maya or Cinema 4D with just a trackpad and you'll realize how well Blender works with a trackpad. ;)

With Blender, it's not only a matter of learning the key combos, but it even has on-screen controls by default so you can at least use that. Maya used to have something similar, but they pretty much got rid of it. It's possible to configure Maya to make it easier to use with a trackpad, but the configuration for doing so is horribly obtuse and messes with mouse usage.
BitClout, With all its glory, and all its horror. Wait no, without the horror
I just clued my UX people into these last year. I love poaching concepts from other areas of engineering for software. Something about linking to a physical phenomena just makes communication so much easier.
People have been wanting it for a while now, a platform that allows you to invest in people. You could invest in youtubers, musicians, or just someone that you know has got what it takes to make it. You can invest in anyone, and share their success.
BitClout was a valuable first-mover in the social tokens space. Everyone was excited about being able to invest in people, it was just the execution that suffered. Bitclout's user experience is complicated, requiring multiple transfers through different crypto exchanges. Additionally you could not even pull money out of BitClout, once your moneys in the platform, its stuck there. However there is another company, doing things very differently. You can invest in people through USD, and you can trade, sell and cash out freely. Osilate is trying do this business right, Osilate is trying to make the starving artist a thing of that past. Currently Osilate is gathering seed funding, and putting together a dedicated team that shares the vision of where this could lead. A new way to determine a persons value.

ICE Pipistrel: "Poweredby the Rotax 912 80 HP engine it burns only 2.5 US gal (9.5 litres) of ordinary mogas fuel per hour"[1]

$6/gallon would be way on the high side estimate for mogas, so say $15 total, so we're sure to be generous.

Electric Pipistrel: "The cost of electricity per hour of flight is roughly between $4 and $6," said Krzysztof Będkowski of Pipistrel Alpha Poland."[2]

I can't work out how $4-6/$15 is 1/10. Is is attractive, for sure. Again, I'm not disputing electric is cheaper, but the claim of 1/5th the cost is pretty extraordinary.
