I appreciate that this is mathematically interesting, but from a practical standpoint, they should focus on “the emissions from gas stoves combined with an absence of fresh air inflow and poor exhaust outflow” if they want to see actual change.

Exactly, right there in the article theres a highlighted quote mentioning this:

> Now, the flight duration is too short, and the degree of difficulty too great. But this was also the case for the Wright brothers

I think the next step for Jetpacks is to develop automated navigation/stabilization systems. We want a Jetpack for which the normal state is flying at a stable height, then with some kind of 3D joystick we can move steadily up, down, front, back and sideways. I think all of this is currently achievable but too expensive to implement.

Also, the amount of energy required to lift a person is just to high, so until better ways to store energy are developed, the "backpack" form factor for storing energy will not cut it for practical flights.
I think a parachute would be pretty easy to accommodate, at least an emergency one. Maybe it'll still hurt, but cut the pack loose and hopefully you would survive. Not everyone survives helicopter or plane engine failures either.

I certainly don't think jetpacks are a relevant tool for society outside of really niche use cases. If we don't even trust people to fly small drones around the public safely and without FAA regulation and licensing, in what dreamland would we all be able to fly personal jetpacks to the shops, or even recreationally? There are way cheaper, way safer ways to get airbourne as a private aviation enthusiast, so I can see why jetpacks really don't scratch enough itches to have gained popularity.
it does feel like we made lots of progress though. as we need less fuel for them, they get easier to use, and safety improves we should start seeing some real use cases
But why not just type "aodaliya"? If you have the muscle memory for it already, it seems like abbreviating and still getting the right result would take more time than it was worth. Even on a phone I'm not seeing a win.
I feel like you could describe cars the same way:

You've got two axis of movement at 60mph. Stray a couple feet left or right and you die in fiery inferno. Stop too fast or too slow, same deal. Maybe appropriate for highly-trained specialists, not for every-man's garage.

My point is not that "cars are death machines no one should own," although there are certainly those who hold that opinion. Rather that inherently dangerous things can be made relatively safe with enough systems around them: roads, signs, traffic laws, licenses, seatbelts, and so on.
More realistically, wouldn't they be better used as locating beacons? Find the magnetar with a frequency of 18mins18s, then turn left and go just a few light years until you reach Sagitarius A*. you can't miss it!
I feel like "You can move things from one to-do app to another to-do app!" is not really a compelling answer to the question "Why would I want to build blocks with the Block Protocol".

The amount of time you spent trying to keep others safe is washed down the drain when you give up for no reason other than you’re tired.

People would love to fly, but in the magic carpet sense. When you look at the dirty and dangerous physical reality of what a jetpack is it's obvious why no one wants one.
It's a pet peeve of mine that people think that sci-fi authors writing decades before the tech exists somehow got the design right, just because Hollywood made some pretty moving pictures that fired up your imagination.

It's hard enough to design things in the real world when you've got the tech in hand. There's no way to think that people got it right decades earlier with even larger disadvantages.

The reality is we don't have jetpacks because jetpacks suuuuuuuuuck. Paramotoring turns out to make a lot more sense. It may not be the picture in your head, but it can be real.

Also, we don't have flying cars because flying cars suuuuuuuuuck. We don't have heavy-duty voice interfaced computers because they suuuuuuuuuck. We even have the tech now for those, and they suuuuuuuuuck as the only interface. (They can work if you're dedicated and have no alternatives, as people program with pure voice interfaces, but they only use them because they're the best alternative they have.) Computer interfaces don't look like LCARS Star Trek interfaces because those interfaces suuuuuuuuuck. And so on.
One thing to note is that court decisions are not required to be scientifically valid. For example, a court could find a company liable for damages, even if the plaintiff lacked any scientific evidence (or lacked evidence surpassing a reasonable doubt, or whichever standard applied in that case). That doesn't "prove" anything in a scientific sense. Further, the case found that vaccine's dont cause autism, the opposite of what rogan said.

Also, the rogan tweet links to an article written by Robert F Kennedy Jr, a well-known anti-vaxxer who recently had to apologize for saving covid vaccines were like nazis.
What difference does it make who demonstrates it? All that matters is application, performance, and whether it is fit for purpose.
Exactly, you need to be credible and non-threatening. There is an history of a Japanese pentester that was always allowed to get into the datacenter because everybody trust a Japanese engineer.
Yes! But analyzing private companies is little use because ultimately they are authoritarian. That will somehow have to change.
Ah, then I guess I'm the fortunate European here. Too bad they don't have an equivalently great option for non-Eurozone.
a widely usable 'jetpack' would actually be more like a ducted-fan coaxial octocopter that you wear, with flight stabilization/onboard flight controller not very dissimilar from a large commerical cinema filming octocopter.

if it relies on the person's skill to fly it and has a 5-10 minute max flight time, of course it'll be a niche thing...
Not that I like the millimeter wave scanners, but like the metal detectors I think they use low-energy non-ionizing radiation, so its not really a change in the kind or significance of radiation exposure.
Someday, helicopters will operate like video games, due to complete flight software stabilization and abstraction of the horrifically complicated control surfaces. This is already starting. But uptake is slow[1]

At that time, we can revisit jetpacks and use onboard software to completely abstract the horrifically complicated control problem.

This is pedantic of me, but: the Internet isn't losing that property. Social groups on the Internet are consolidating their behavior onto individual networks/ASes, which then go down.

It's a social and political problem, one that people can solve by changing their behavior.
A common thread I've seen is that preference for declarative or functional often correlates with how you approach systems.

Many of our traditional operators / SysDE greatly prefer reams of declarative configuration. They like to be able to look at a system configuration and understand it in totality. Even if there are abstractions. These folks tend to run other people's software, be great at reading manuals, and debugging systems they can't see code for. The reasoning for a given setup is usually in a wiki or is common knowledge (to some extent) in their heads and the organization expertise of running that software for years.

Most of our engineers (SDE) hate declarative as it's not DRY, really boring, and doesn't encode the intent as you said. Code based solutions let a developer (who groks code) understand some of the rules behind WHY (to some extent), and developers tend to be lazy and want to move that knowledge out of their head and into computers so they don't have to deal with it.

Both sets of people can be right.
I think it's less that inflation is caused by the national debt, and more that it will be nearly impossible to pay off the debt without massive inflation. Certainly the Fed is in a box with the debt, as it can't raise interest rates without massively increasing US Government debt payments. The only solution seems to be to keep rates low, which results in inflating away the debt.

I've been involved with hiring consultants before (in UK and Norway, using consulting companies like Capgemini and Sopra Steria), and it was always the case that it was a lot more expensive - but yes, it means you have instant access to a large talent pool. It also meant that if someone didn't work out, we could swap them out with 2-4 week's notice, depending on the provider.
I have no problem with the statement "completely unexpected that nobody thought would be able to produce this kind of emission".

Nothing is being downplayed; the history of astronomy is littered with events like this. If they get enough data and can explain it, astronomy will be updated slightly.

Building your own carries it's own set of risks. I can't afford the infosec, IT, devops, etc. that a large tech company has. Sure if I build my own and get hacked, I may have more ability to directly effect the situation, but I will likely have to spend much more of my time wrangling tech and may end up being more likely to be hacked overall.
I've hired a lot of contract developers in Argentina over the years and most now ask to be paid in Bitcoin. If I wire them USD, between fees, loss from the "official" exchange rate, and inflation, they lose 15-30%.
I think with a active control unit safe operation should be possible. There are fighter jets that cannot be flewn manually (unstable flight behaviour). Probably range and use case is the problem.
Unification and constraint solving is a big reason why. Prolog is definitely the easiest language to write a type checker in because it not only has unification built in, it is also excellent at navigating trees like type hierarchies.

Something I've personally used it for was navigating the parse tree of some T-SQL I was analyzing (it was 100k+ LoC so manual analysis was out of the question). There is a pretty good C# library for parsing T-SQL, but it is unwieldy to use since it relies on visitors and has tons of different typed nodes with a huge inheritance hierarchy. I ended up exporting this to JSON including type information and initially used jq for analysis. However, even that ended up being hard to manage so I switched to Prolog and it was way easier to write. In terms of this project, I particularly liked that the code was so dense and expressive that I could write the program by first testing things out in the REPL.
On a single CPU in an ATX case, yes, definitely, with power to spare. Possible on a modern Raspberry Pi too, if you hooked up USB modems that FIFO buffered on the modem itself, used something like an Arris multiline modem that will connect over Ethernet, or alternatively, could figure out a way to attach a 200+ multiline PCI modem card to your Pi. Though you'd need to talk to your telco if using an Arris as they used this weird parallel connector that I don't recall the name of.

While indeed people do not use jetpack in a day-to-day manner, they are becoming slightly more 'available' than you portray.

See this video where one of the corridor crew members participates in a jetpack training.

Clear doesn't get you past the checkpoints, it just gets you to the front of the line. Gross on a "class warfare" level, but you go through the same security everyone else does.

It's not really a "new frontier being misunderstood" though, it's very clear what it's value proposition is, and it's also clear from our history with aviation so far, what the challenges are. As I said in another comment, we don't even trust people to fly small drones without certification and FAA regulation, there's good reason for that, being in the air is nothing like being on a road.

I feel somewhat in the middle between both of your opinions.

The "average joe" in some regions may not fly regularly, but around here there's many farmers with Cessnas that do routine work.

Currently, if you have a use for it and are somewhat competent, it's practical to fly and not out of reach for the common man.

But in no near future do I see them reducing the restrictions, flight hours, air traffic protocols, etc.

That being said, I don't see much practicality for a jetpack other than sport or rescue.

We also have supersports cars that can go 200 miles an hour and accelerate 0-60 in 2 seconds but not many people have one. Current jetpacks are certainly interesting but almost useless besides maybe a few very specialized things. As are supersports cars. And both are prohibitively expensive for most people.
I can't say I understand the full context, but not really.

Absolutely false as noted by the other reply to this comment.
I think the earlier posters are pointing out that no one else seems to be able to safely operate the thing, which suggests that it might not be fit for purpose.
The chance of a child dying from coronavirus is infinitesimal, the response should be proportional.
The amount of training matters. If it's always him, that has some implications on how hard it is to turn into a product.

BankID: A system with a secret spec, where the bank holds your secret key, there is no transparency log whatsoever (so you have no idea what your bank used that secret key for), can be used to authenticate as yourself almost everywhere, and where you can get huge, legally binding bank loans in minutes (and transfer the money away) with no further authentication.

Oh, and if you choose to not participate in this system, enjoy trying to find out the results of your covid test :-) (I ended up getting a Buypass card, but they officially support only Windows and macOS.)

That held true until prices dropped and computers were actually useful to individuals and not room-sized machines.
Thanks for the feedback. My aim is to motivate others to make computer science more inclusive however they see fit. I thought the NFT could be one way to signal a desire to make computer science more welcoming. Totally understand it may not come off that way.
My employer (~100 people) uses a combination of job fairs (organized e.g. by local universities), recruiters, LinkedIn, employee network incentives and (social) media advertisements.

Your home page is just one point where you should post job openings. StackOverflow has a jobs board, for example, as do many industry-specific magazines.

Another option is to poach people from advertising and consulting agencies. Many people use them to get a foot in the door of the employment world after university/vocational training and then, once they're sick of having to balance ten projects a day, shift towards one stable employer.

A western corporation gives people free voluntary access to a certain part of the internet and in exchange sucks them for their data (in exactly the same way that it does this to perfectly middle and upper class western users of the same platform) and this is somehow comparable to colonialism, but with "data"?? Oh please, enough with the absurd cliche leftist caricatures about western technologies being hegemonic and so forth. Yes, some of them are, but why not ask the billions of FB users in the developing world if they'd prefer to have companies like Facebook simply leave under the present circumstances? I happen to live in a developing country where Facebook use is widespread. People criticize the company's crap regularly enough, but many of them also willingly, even happily use much of its platform. They're not being forcibly "colonized" in any coherent sense of the word.
> However, one thing I must point out is that climate change is a complex problem with no easy solutions.

Indeed, but right now we are doing almost nothing meaningful. We shame people from taking vacation flights once every couple years but don't ban short distance "business flights" for corporate executives with a completely bonkers view on how important they are. We still don't mandate the end of "bunker fuel" burning on ships or the usage of land-line power of cruise ships. Instead of building electrified freight and passenger rail, large parts of the rail network run on decades old diesel engines, large parts of freight runs on trucks and in the US the word "high speed passenger rail" is as inconceivable as "fair minimum wage".
Right, in this case you are totally right.

In my school however, it is explained for general-size systems. With this I do have issues.

Gas stove is always polluting, even when it’s turned off
I have a friend living in Argentina. His father-in-law is a businessman with a factory. Like many successful people in Argentina, he is a master at exploiting chaos for personal benefit. The father-in-law praised inflation, explaining it was a useful tool for people like him, and offered the following story:

I was walking down the street and found my wares being sold in a shop that doesn't retail for me. Doing some digging, I found incontrovertible proof that my foreman of ten years---ten years!!!---had been stealing from me.

Did I fire him? No. It is impossible to fire your employees, even for provable malfeasance.

Did I sue him? No. You lose 95% of these kinds of cases.

Did I tell the police? No. You can't get the police involved with anything important, like my business, they are too corrupt.

So what did I do? I simply told him I would never give him a raise again. And he understood that---due to radical inflation---his salaried buying power would keep dropping and dropping, until it was chiseled away to nothing. So he quit.

[edit: I am in no way suggesting that FIL was the moral actor in this story, I don't know if he was or wasn't screwing his foreman into poverty before the theft. What I found fascinating about this story was how things were systematically fucked in across so many possible dimensions, that individual instances of corruption and inefficiency and lack of faith are intertwined. i.e. there's a whole rat's nest of problems to untangle and a point intervention is unlikely to prompt broader change. Also see interesting discussion below about root causes of the inflation, which connect to some of the anecdote above: https://news.ycombinator.com/item?id=30101931]
