>Well, nobody guarantees growth, especially short term.

But you're focused on long term remember? Long term, the government is the closest anyone can come to guaranteeing growth. If the government can't grow the economy long term, way more is going wrong than just currency, soon enough it won't matter if your money is in beanie babies or BTC, there's going to be a lot of gnashing of teeth.

>But 50% loss after a 1000% growth is still better for many people experiencing hyperinflation. Bolivar lost more than 90% of its value in the last 6 months [1].

Perfect example, who cares if you have all the BTC in the world if you're in a country where there's not even food to buy? So you figured it out and hoarded BTC, did the shopkeeper? Let's even say they did, well did the power company take BTC? Did the power company's stakeholders and employees take BTC? Did those people's bill collectors take BTC?

Because if not, you don't have food, and that's that.

Long term growth of the economy is literally one of the things countries are built on, if it doesn't happen and hyperinflation takes a hold and the currency is down 90% in 6 months, having 10 years of BTC saved up is going to do much.

The people who were rich enough to have a sizable horde of Bolivar could easily transfer it out of the country at the start of hyperinflation, everyone else is SOL. Same with BTC, if you have enough to leave you leave, if you didn't have enough to leave maybe you're even worse off when the power goes out and the mobile networks start flaking and you don't even have loose leaf which could maybe be traded in one day for a valuable currency.

Inflationary currency is designed to "lose value" as the entire country "gains value", hard to call it "losing money" at that point.
Military drone operators will be found on military bases in military uniform. They will be easily identified as soldiers if captured.
Performance of internal combustion engines varies greatly depending on altitude due to thinner air. This is even worse on hot days. That's not the case with an electric motor. As you get higher, you need to push more air, but since the air is thinner, it's easier to push. Most likely and electric motor with a variable pitch propeller would be extremely efficient. Electric planes would get all the benefits of high altitude flight (namely thin air means less friction) and none of the downsides.

As someone else mentioned, if the batteries get too cold you run into other issues.

Trunk-based development: an interview with Paul Hammant
Electric trainers (initially) and short-haul passenger aircraft (in a decade or so?) will succeed simply because operating cost savings make them extremely compelling. Not just fuel savings, but reduced maintenance costs and increased reliability.

As for electric isolation? Yes, if electric aircraft work like electric vehicles, the high-voltage system that powers the motors is completely separate from the low-voltage system that powers the electronics.
That is absolutely terrifying.
I don't think anyone is going to really curb emissions any time soon.

We will probably try to extract carbon from the atmosphere and add chemicals to the air that promote cooling.

Anyway, M-x describe-mode (normally M-x desc-mo <Tab> is enough) will print a complete, if intimidatingly long, description of key bindings for the current buffer.
Fair enough: I agree that plenty of people prematurely ask someone rather than try to figure out a solution by searching, thinking, experimenting, etc., and using Slack as an asynchronous channel will generally encourage people to hack a bit more at their problem before instinctively distracting the person next to them.
This is wrong on many levels:

1) General aviation doesn't rely at all on the weight difference from fuel burn for flight planning (I am IFR certified and fly Cirrus SR22s). My fuel not burning in my wings wouldn't change anything, as I'm constrained by takeoff weight not by landing weight, and I don't climb into the flight-levels high enough for my current weight to matter (that would require FL22 or above, and I like my breathable oxygen).

2) General aviation certification, while expensive, is far from the cost of commercial cert, especially for VFR aircraft. There is no reason why they can't certify an electric aircraft, and they have funding from Subaru's investment fund. Pipistrel (electro) did it for their ultralight.

3) Of course the motor's electrical system is separate from the aircraft's other electrical system, that's aircraft certification 101 (being able to through the master switch deactivate alternator but not battery power). On top of that 12v instrumentation is (obviously) on a different power level than an electric engine, so the batteries will be different.

IFR certification will require 2 instrumentation power source backups (like BAT1/BAT2 on my cirrus) which really isn't a problem, when you've put a 92kWh battery on a plane you can put 2 0.5kWh batteries as redundancy.

(for what it's worth, I'm currently waiting to buy an eFlyer 4).
> allow complex layouts that Flexbox and CSS Grid makes possible

What version of CSS do people complain about? By chance are you talking about bleeding edge unaccepted CSS proposals?

In any case, the list of CSS improvements is long. Off the top of my head:

* Remove min-height, max-height, vertical-align, text-align, etc. in favor of unified Flex model.

* Rename color to font-color.

* Default to box-sizing (or remove content-sizing)

* Make <fieldset> stylable by CSS.

* Make inline styles work with pseudo-selectors, or remove inline styles altogether

* Reduce the number of units
And phone CPUs can be more complex than most desktops, afaik big.LITTLE is fairly common (multi core, with different performance / power tradeoffs between the cores).

They should be treated like jupytr notebooks, used for exploration but productionalizing excel workflows is not fun at all especially if people have gotten into the ActiveX/VBA control stuff.

I don't know the answer to your question, but some factors that might skew the distribution could be how annoying and expensive it is to keep a car or park in each city, prevalence of recreational activity that encourages or discourages a car or truck, and the like.
The protocol isn't the issue.

It's like SMTP, if nearly every conversation went to list-all and our email clients were designed to intelligently allow us to choose what sub-section of the thousands of messages a day are important to us.

Or, like we already knew, it's an expensive, intrusive, proprietary upgrade of IRC.
It IS true for the prototype. Siemens is really good at grabbing these orders for production aircraft and getting their name in press releases, but the actual motor used for the prototype according to the FAA (who I don’t recommend lying to) is the EMRAX one.

EDIT: And EMRAX motors have shown up on lots of other electric aircraft. My day job is making novel electric motors, and their motors are incredibly tough to beat. I have much respect.
In terms of "dom buffer" there's a proposal in the works for the buffer "other half" to `window.requestAnimationFrame()` to queue DOM reads (where RAF is the place to queue DOM writes). So far I've heard it has the unimaginative and odd use of grammar name `window.requestAnimationFrameAfter()`.

Still would be too low level to easily work with though without a framework like React.

> ETH transactions avg like 10 cents: https://bitinfocharts.com/comparison/ethereum-transactionfee

That's still significant for small transactions. Beyond that, will it scale well enough to cost only 10 cents if it becomes the new Visa/Mastercard? The transaction rate of BTC/ETH is still almost negligible when compared to mainstream payment processors.

>Coinbase owns an exchange, so they don't have to commit every transaction to the blockchain, so it's peanuts for them.

My point exactly. It's not a Bitcoin card, it's a Coinbase card, the cryptocurrency aspect is tangential. This is not cryptocurrency going mainstream, it's the mainstream taking over cryptocurrency because it's just so much more convenient to have a Visa card than a Bitcoin or Eth wallet.

Not sure why you're getting downvoted. It's plainly true that hash tables accesses are only O(1) amortized. The real worst case is ~O(n log n) (or whatever the bucket data structure is) in the case of collisions and/or filling up.

And we can always pre-allocate a huge array for the buckets, but the behavior of the hash function is always going to be a risk.
What if the battery used in these planes are like my phone batteries.

After using my phone for a few hours, the remaining battery will be down to 25%. And in 5 mins, my phone will be off due to the dead battery.

Once it happened to my EV. The battery was down to 50%, and then suddenly drop to 10%. Luckily, I was very close to my home.

I wonder if progress being made in micro-turbine generators would one day allow them to be used in planes. Having a bank of generators inside the fuselage could making flying a lot safer. I imagine planes can be made much more aerodynamic as well.

Rustc is faster than GNAT Ada in some micro-benchmarks, most of them total worthless for production code running in airplanes, medical devices, train security systems.

If I am supposed to now start coding micro-benchmarks across all AOT compiled system languages against Rust, then I don't have any issue losing Internet points.

So now the point isn't anymore that a language cannot change execution speed by changing implementation, rather how it compares with Rust.
> VFR is the most dangerous situation to lose all systems in your aircraft. You're low to the ground, and relatively slow...

I disagree. You don't have to be low to the ground to fly VFR. You could be at 10,000 feet. You don't have to be slow to fly VFR. You could be flying VFR in a turboprop twin and pushing 250 knots.

If I was going to lose all systems, I'd also prefer to be flying in VFR conditions where I can see the ground and have a chance of choosing somewhere to make an emergency landing, rather than, for example, over mountainous terrain in cloud.

Every GA pilot is taught and needs to practice engine out emergency landings in order to pass their bi-annual flight tests.

You still need a craniotomy, but the dura remains mostly intact. Rodent dura is a lot thinner than in primates though, so it'll be interesting to see whether it works in larger animals. I'd also like to see some actual data showing that these electrodes last longer. People can keep Utah arrays going for a few years, even though the implantation surgery is more invasive. (craniotomy + duratomy + pneumatic insertion).

Still, it's nice to see some innovation that might eventually work in large animals and humans, instead of yet another thing that only works in transgenic mice.

An interesting question is how can you parallelize it? Suppose the data is huge, but you have many available threads, or machines..

Suppose there are N nodes, each of which owns part of the array. So one way is for each node to broadcast each entry to all of the other nodes. As each node receives a broadcast, it checks its array for duplicates, and deletes them.

When I took programming classes in uni it was the OOP section where I would consistently get 100% on tests. Everything else was 75-80%.

OOP is one of the few parts of programming that are genuinely enjoyable. Sometimes I open up Ruby and make an OO model of something from my work (mathematician). So I'm not asking because I'm bad at it.

But it seems like there are only two programming paradigms: object-oriented and structured (classical functional programming (like you find in Scheme) is really structured programming without loops and variable assignments). And the problem is that structured programming is not temporally infinite: it breaks down most ungracefully past 150k lines of code.

You can't tell me that the only temporally infinite programming paradigm is OO and that nobody invented anything else in the intervening 30-40 years.

I think the problem is largely isolated to companies in decline or stagnant -- which unfortunately is most companies.

At a growing company, if you're a growing individual, there's room for you to rise.

At a stagnant or declining company, if you're outperforming your boss, there's a strong incentive for your boss to want to keep you down to keep his/her job.

In a growing company, your boss might be happy to get your promoted to his/her level. Instead of subordinate, now you're a potential ally on the same level. I think in a healthy environment almost anyone would see that as appealing. In a stagnant company, that could be mean your boss loses the job. Almost anyone would see that as unappealing.
I feel like a unique ID isn't enough to protect your identity from an analytics provider, especially if they're receiving analytics on you from multiple sources.
I would WAY rather lose my engine and instruments in VFR conditions (where I can see the ground and see where I'm going) compared to IFR, where I can't see where I'm going and I'm relying on my instruments to navigate.

This is why IFR certification (more dangerous and skilled) is an addon that takes dozens of hours to complete initial training for, and then requires Instrument Proficiency Checks every 6 months to keep current on.
The idea of thinking that _too slow a rate of growth_ is a business risk is somewhat confounding to me.

Isn't every business at risk, by this definition? This seems like a good way for investors to "scare the pants off" founders by reminding of them of an existential threat, and therefore _only money can solve it_. Not only that - only _a lot of money_ can solve. Convenient!

Couldn't the founder simply re-allocate retained earnings toward mitigating risk? Then you are protecting from the downside at the expense of growth. One could also argue that this is money deployed much more wisely - ie. in a capital efficient way - over known risks than speculative "target niches" or feature creep.

At this point, your only argument is that you _may_ (but not necessarily) be growing less quickly.

And to that, well you can use that argument literally against any business. There is a "threat of a potential well-funded competitor." This doesn't seem very tenable to me.
For the most part...yes.

Also: This means there is enormous potential to pollute their signal with tons of false noise. I hope(dangerous word) that this has already happened, or is in progress.

Batteries not getting lighter with reduced charge is relevant in that it's not uncommon to trade reduced range for increased payload by carrying less gas. With batteries having a fixed weight, you don't have the ability to make that trade-off in an electric aircraft.

I always wanted voice assistant/chat bots to feel like a work of IF. You can kind of navigate a space textually, and perform spells/commands. Only difference is that there is a connection between the text and some representation of reality.
That is actually my point. Remember the goal is to nub an array into a set.

Perfect hash tables where there are no collisions are O(1) but they're not suitable for casual use, you need to guarantee your data set never collides hash buckets. That is why most implementations of "maps" in programming languages map to very wide trees after a certain size. A common example is HAMTs (Bagwell is famois for these).

They're flexible and perform well on modern hardware for arbitrary key lookiup.

If your constant time hash tables is taken to the worst case (as we do in O analysis) then that operation would collide with the same bucket and require a potentially full linear search of the data every time to see if it places into your oversubscribed bucket. That's O(n^2).

You could make it better by sorting on insert. That's O(n log n) because it's comparison based.

I've provided a much better solution and links to code that does it. Maps and hash tables don't solve this problem any better than just sorting the array.

It's worth noting that if we're ignoring preprocessing and the domain is well-constrained, we could probably make O(1) to do a bunch of these ops in bulk if we really wanna go off the deep end. But that's cheating because we'd be ignoring construction costs, as you are here.
