What would a modern authentication on a peer to peer system look like?

In a large chat, where you're basically playing a game of telephone, you could sign your messages. At scale it would be infeasible for every user to retrieve a copy of every other user's key to validate messages. Perhaps having optional validation (e.g. you see an important message and you can choose to validate it, that reaches out to the user, gets their key, then checks the signature).

In smaller chats it would be feasible to hold every user's public keys and retrieve them directly. Then allow the messages to be relayed between participants, or encrypted and relayed along the larger network.
So the reason is that "Theodore Roosevelt" links to "Freddy Fazbear" (ctrl+f for "Articles related to Theodore Roosevelt" and then click it and then click "Teddy Bears") which redirects to "Friday Night at Freddy's". So, technically, there is a direct link there, albeit through the categories dropdowns. Unfortunately, Wikipedia doesn't have anything in their database dumps identifying if a link is in the article itself versus the categories dropdowns or sources, so I include them all.
Road rage is one of the bad emotion-induced states as well. Something competitive about human nature makes us bristle at minor events like another car getting ahead or cutting in line, and likewise makes ourselves do dangerous things.

Everything we spend money on is being manufactured more power efficiently, is more power efficient on its own, and grid demand drops as adoption of new efficient gadgets and individual solar expands?

At home we went all LED lights. My office followed suit. Even my city swapped the night time street lights

Sadly we had almost every appliance in the house die in the first 4 yrs we owned it. But they’re all new efficient models now

Fewer desktops, more tablets and phones. Our big TV is only on 3-4 hrs a week (but it too is a more power efficient model)

A lot of effort has gone into battery storage and efficiency this last decade.

Well technically you could be telepresence into the meeting because your car can be outfitted with a nice TV/monitor, audio recording equipment, and high speed wifi... so you can have meetings while you drive to work. Or you spend your quiet time in the car working, and instead use office time for meetings.

Besides, in the hypothetical self-driving future the transit times will likely be far more predictable than it is today... with AI running and optimizing everything.
Thanks. I think it’s a good decision, it seems like a classic example of needing to recognize sometimes going against conventional wisdom makes the most sense given particular circumstances, like gaining critical mass in a start up. As to where the right decision might be different for a later stage company.
> But back to Flutter, it uses Dart. I honestly don't see the point of Dart. Maybe it's just me but I don't want optional typing, or rather optional type hinting. I want static typing. The romance with dynamic typing over the last decade I think is on a downward trajectory with the rise of the likes of Go (really a better Python) and Rust.

FYI Dart2 is no longer optionally typed.
HiRes utilized the atmospheric fluorescence technique that was pioneered by the Utah group first in tests at the Volcano Ranch experiment and then with the original Fly's Eye experiment. [0]

The cosmic ray hits a molecule in Earth's atmosphere, which causes it to ionize. When it regains electrons, they emit UV light, and the detector catches this while scanning the sky. [1]

Life almost definitely exists elsewhere, and this is coming from a religious person. The number of star/planet combinations out there virtually guarantees it mathematically. The problem is that space is too large and vast and the speed of light too "slow" to be able to reliably "scan" the universe fast enough to find life.

Two scenarios (at least):

1. God exists and specifically seeded life on Earth.

Even if this is the case there is still no reason meteorites couldn't carry microbes from Earth to Mars. It doesn't seem like God cares about quarantining life to earth, seeing as we made it to the moon.

Also, why bother making a universe so mindbogglingly huge and vast only to put life on a single planet? Makes more sense for God to seed countless planets out there with life. And indeed there are a few verses in the Bible that imply Earth is not God's only creation.

2. God does not exist and life emerged naturally.

If this is the case then that means life can emerge naturally somewhere else with identical conditions, and given the number of stars/planets/time elapsed, this seems like it could be a high probability (hard to know, though, without understanding exactly how life emerges).

When I get time I might actually debug this to see what's going on. I'm quite curious what happens when you access the pointer again.

Thats not necessarily a bad thing if you make transportation efficient enough. Self driving pod that hooks up to public transport, giving me privacy the entire time? Sure.

2 hours is time for art, digital or pen and paper (I draw while on airplanes and such and have learned to compensate for bumps and things). I could knit. Watch things. Read. My spouse would sometimes make music. Some of these are good even if the commute is shorter, and would be an improvement for anyone commuting a good distance already due to traffic and whatnot.

4-5 hours? Split sleep schedule. (I have no children).

It also means folks can better commute to work from small farming towns that lack jobs. I know that an hour commute each way (by car) is too much for me, but I've had to just to make decent money. This was living in the midwest, mind you, and it might be different other places. It wouldn't have been an issue if I wasn't actively driving.

Yes, I do understand that some of the hope would be that people live closer, but that's the hope and push now and it breaks often enough.

In before the usual "imagine how people would treat those cars": car sharing already exists in many cities, and the driver is usually asked before starting the journey if the vehicle is clean, and if it isn't, the previous driver will be billed/fined, so that's a solved problem.

> Every light in our house is LED and I still teach my kids about not wasting energy and turning things off when not in use.

Are you certain that it's wasting energy, though? You have to account for the time spent actually turning the light off, as well as for the psychic cost of having to think about whether to turn it off or on.

I'm reminded of one of my old offices, where some office busybody turned off the lights in the bathroom. They were fluorescent and took awhile to brighten up, so of course this meant that one would enter a darkened room, turn them on, and then slowly get some light. Was it a huge deal? No. Did it make our lives worse than just leaving the lights on? Yes.

> Maybe it’s because I grew up with incandescent bulbs, but I can’t stand the thought of random lights being left on for no good reason, even if it costs 40 cents a year to keep lit.

At 40¢/year, leaving it lit costs .11¢/day, or .0046¢/hour. At any reasonable rate for your time & mental energy, it makes sense to just leave it lit.

Gaining and losing orbital energy are both equally hard in the vacuum of space, it's not harder to get from Earth's orbit around the Sun to Mars's or vice-versa - though it takes somewhat different amounts of delta-v to go to an Earth-Mars intercept from them. The reason it's easier for ejecta to get from Mars to Earth than vice versa is that Mars has a shallower gravity well to climb out of before making the inter-planetary trip. It's a lot easier for an impact to impart the ~6 km/s velocity you need to get from the surface of Mars to hitting Earth's atmosphere than the ~13 km/s it takes to get from Earth's surface to hitting Mars.
Same here. The cost of electricity and the cost of distribution are two separate charges here, and they are about the same.

There's a few.

- Flutter renders the UI itself rather than using native components, so you get the same experience on both iOS and Android.

- Flutter uses Dart, which can be compiled AOT, rather than relying on an interpreter.

- Flutter is completely open source, tools, engine, all of it. You can go a long way down before hitting iOS platform code, for example, that you don't have source access for.

There others, but those are the biggies for me.
No. Professionals in engineering or the trades have to know the regulations that govern their industry and abide by them.

What many SVers call "innovation", other industries would call "reckless".

How embarrassing for us!

EDIT: In terms of regulation, we're practically chiropractors.
This is good news. Hopefully it will gain more traction once it becomes stable.

It's I suppose possible to hit a simple optimization evolution hasn't found yet, but that's rarer than people seem to think. The major examples we have are either things which evolution lacks the tools for (e.g. mechanical prosthetics) or major biological leaps (e.g. your antibiotic example).

The things that look quick and easy like "eat some willow bark extract" have tradeoffs, even when they aren't obvious. Taking 'painkillers' to the extreme - morphine - makes it especially obvious. It's generally a terrible idea unless you've recognized that there's a problem and gotten someone else to take care of keeping you healthy while you're out of commission.

Yes, but.... there is a lot of but there:

Technically speaking (literally), a shack in Gangxia, Shenzhen can have market value from $1m to $2m, but nobody will ever sell it. They have no value other than of land under them.

Rents for a room there were around CNY400 per month 5 years ago.

80ies era apartments - also cheap, but quite a lot of them are in even worse shape than property in villages.

post 2000 housing - gets better, actually livable somewhat. Look for 4k CNY in good locations.

Western like proper highrise apartments - no less than 9k, availability is smallish. Everybody is looking for then. I was looking for one in Huafu area, but they just go too fast to even get sense of a price
For one, the human has a brain and human sensors are less easily fooled despite being able to "see" less. LIDAR technology combined with ML is so poor that it can easily be fooled by a stop sign with a sticker on it.

A human has context where a machine does not. A human automatically knows that a ball being thrown in a yard can end up in the street.

A learner's permit also requires that a licensed driver be present. So there's a built in redundancy for decision making.

Machine learning or not, computers are simply profoundly stupid.

I'm not against autonomous vehicles but I'm fairly skeptical about them. They've improved a lot in a basic way but they don't handle corner cases very well. Unfortunately, driving involves a lot of corner cases due to the complexity of the environment.
> ...and the cities were ill prepared to deal with that.

For all the faults around Europe with traffic, I think they did far better adapting to cars than the UK. Mainly by preserving some of the alternatives better.

The Netherlands has infinitely more sensibly integrated public transport, and provision for cycles than we will probably ever have. At least that's my perspective as an occasional visitor.

Postwar rebuilding here gave us internal combustion as the answer to all, leading to much, now regretted, removal of rail lines and trams. Not forgetting the many people-hostile choices like cutting communities in two (e.g. Mancunian Way) and giving residents a motorway right above the house (Birmingham, M6). Trying to undo those choices always comes with a bill in the £bns for the shortest length or rail or tram.
If your car's brakes fail, it's probably a mechanical fault due to natural wear and tear, for which it is easy to avoid assigning blame. If a car's autonomous capability spectacularly fails, it's far more likely to be due to a bug at design stage. Many of these bugs are likely to cause vehicles to behave in ways human drivers would certainly be prosecuted for, and we really haven't got a whole lot of precedent for auditing responsibility for bugs in complex software performing varied life-threatening interactions with other humans which replicates tasks humans themselves perform imperfectly and are frequently prosecuted for negligence over.

It would be a strange system which punishes humans for individual serious driving flaws but merely requires them to remedy it for introducing systematic serious driving flaws.
Maybe, but it is worth pointing out that some VC firms are fighting the good fight to transform New York into a rival of Silicon Valley. I'd especially praise Primary Ventures for their efforts:

"Long Live Silicon Alley: The Inaugural NYC Summit"

http://www.primary.vc/blog/summit-17

I was at one of their gatherings not long ago and they pointed out that New York is the world capitol for domain-specific knowledge in at least a dozen industries: publishing, law, medicine, fashion, art, education, finance, and more. There is a potential there for a kind of success that will be different than Silicon Valley's, but not necessarily inferior to Silicon Valley.
Life arose very quickly on Earth after it cooled down. Photosynthesis took longer and Eukaryotic life took longer still. Seeing a Martian protozoa that evolved independently of Earth life would be scary. Bacterial mats around a thermal vent not so much.

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

EDIT: It's also sort of scary to think that it took 4.5 billion years from the first life for us to evolve, and it's only going to be another billion before the growing sun sterilizes the Earth's surface.

That latter part is a very serious concern. This isn't hurting big evil corporations who are killing the planet. It's hurting regular lower/middle class Germans who bought cars that they could afford just as everyone else was... electric isn't a financial option for the vast majority of people and diesel has been sold/advertised as comparable to petrol for quite some time...

Like most bad policies it's based in good intentions with some highly questionable/harmful real-world implications.

2. If they say no, ask for another time that works better. People are polite, so many will not say no. Schedule this time immediately and have them confirm on the calendar right away.

3. If they say yes, immediately start asking them empathetic questions that demonstrate knowledge of their problems, followed by, "Does any of this resonate with you?"
