Pressurized cabins are going to be essential for electric flight to have any kind of reasonable speed (and range).

It shows that the most impressive electric aircraft specs are for the pressurized Eviation Alice (1000km, minus margin for contingency, and 250 knots cruise). If you stay low enough to not require pressurization, then you have to compromise the lift to drag in order to have a decent cruise speed or you have to tolerate a really low cruise speed.

Altitude is essential. Bite the bullet and build a pressurized cabin so we can get on with replacing fossil fuel aviation with full electric. https://www.eviation.co/alice/

Doesn't have to be above the Armstrong Limit, but it sure does help to be above 10,000 feet.

Eventually we'll have supersonic electric aircraft. To have sufficient efficiency, they'll need to be at or above the Armstrong Limit, like Concorde. (And perhaps higher, like the 96,000 feet record holder for horizontal powered flight, NASA's Helios... which just happens to be electrically powered. https://en.wikipedia.org/wiki/Helios_Prototype .)

EDIT: High altitude enables you to use an extremely efficient airframe with sailplane-like lift to drag but STILL achieve high cruise speeds. For instance, the Perlan II glider actually has no engine and is able to soar higher than any towplane, above 76,000 ft where it flies at about 250 knots (actual airspeed). Without any engine at all. https://www.youtube.com/watch?v=NnpE5xS1g80

And here's a solar electric aircraft aiming for similar goals: https://www.solarstratos.com/en/challenge/
If it will work flawlessly with
- external dual monitor setup (one/both 4k) via docking station
- battery usage
- fix the throttling and power management issues

it will be great, otherwise it will be the same miserable experience out of the box that you're getting now.

If you're just a reseller of mass-produced goods available at many other resellers, then having a crappy cart design means customers go to your competitors instead.
It will take a lot longer than 30 years to develop and certify such aircraft, then build out the infrastructure. Small general aviation airports just aren't set up to handle a bunch of passengers. A minor decrease in fuel costs won't have a transformational effect. And passenger security screening will still be required.
I totally agree with you. Comfortable suffering certainly seems preferable to unbearable pain, but maybe is not preferable to a daily struggle. My point is eliminating physical suffering does not eliminate existential suffering, whereas eliminating existential suffering with ultimate meaning can in a certain way eliminate physical suffering. For example, many Christians, and people in other religions and philosophies, in the past and even today voluntarily undergo tremendous torture and painful executions because they've found a profound relief for the existential suffering.

People are against surveillance because of 1984. But that's just one possible outcome of massive surveillance. In the end, surveillance is just a tool and it depends on who use it. Have been in China and Singapore, I think surveillance definitely improves the overall public safety. The city population there is very dense. People don't have guns to protect themselves. Having surveillance cameras around at least can help police catch thieves who steals you stuff and run away.

And I see some comments saying that we need surveillance to catch all sorts of crimes. I don't think that's the point of having surveillance, at least for now. Surveillance is to support police. Even if it doesn't catch any crime, only its appearance would somehow reduce crime rate because people would behave better when they know they are being recorded.

Well, maybe? If the SMS takeover attack results in the permanent loss of your phone number, then yes, you have lost everything. However, in most SMS takeover attacks, the attack only lasts some hours, where the attacker has control over your phone number and uses that to pivot into other accounts. With the Authy-style 2FA, they get your phone number, can then recover your Authy account, and get a copy of your encrypted blob, but they can't do anything with it. Any time they try to pivot to a different account, they don't have the 2FA and get blocked (ignoring account recovery attacks that bypass 2FA, that's out of scope). Eventually, you'd recover your SMS/phone account, and be able to download the blob, decrypt it, and have your keys. That's the model I'm seeing.

One protection that Authy should include is not letting someone who has recently performed an account recovery perform a blob deletion. That should require a delay.
Why not just use a smarter compiler/linker that trims out unused library code?
I didn’t downvote you but running a TCP/IP stack inside the JVM doesn’t seem terribly useful. Doing user space TCP/IP can be useful for performance reasons but running on top of JVM is likely to wipe out that advantage.
Age of Ultron's probably the worst offender in the series for—call it the Man of Steel effect, where there's a 20-minute (or longer...) "final fight" and I just wanted to take a nap by maybe the 5min mark. Almost all of them do it a little, though, even Guardians 2. The first Avengers film is notable for having precisely that sort of scene but being engaging nearly the entire time.

Rogue One was a frustrating near-miss. Leaning into genre tropes adjacent to those that were such a part of Star Wars (the original gigantic genre-pastiche film) was such a good idea, and man, it almost worked. I think they just didn't quite have enough confidence in that idea and hedged their bets too much, and of course couldn't resist doing the Interminably Long Gigantic Big Explosions Action Scene. That aside, the fleet arriving and immediate aftermath of that is maybe the only time any of the new movies have given me childlike "Star Wars Feels" like several of the moments in the original trilogy do, so there's that.
Both are used.

Here you can see Steven D'Aprano, one of the dev of the Python stdlib, naming it "splat": https://mail.python.org/archives/list/python-ideas@python.or...

On the other hand, itertools.starmap() is named this way because it does:

def starmap(func, iterable):
for e in iterable:
yield func(*iterable)

Things rarely have one name in computing. Hell I call curly brackets "mustaches" all the time. It's as hard as cache invalidation apparently.

"Learning" here means averaging over many rollouts (i.e. simulation runs) of a policy. Naturally, time only increases in those runs, as you require.
Of course, you can find sloppiness and bad examples everywhere, but you don't prove the theory by a few examples. Perhaps cars was a bad example. My point was that the Japanese and European carmakers always tried to get better performance out of engines without scarifying fuel efficiency. I am not a European nor an American, but I lived on both continents. Visually ( I don't have a statical proof) Americans use much more plastic and produce more plastic garbage than Europeans. A lot of people in Europe genuinely care about the environment and are ready to sacrifice convenience for the environment, but very few people in the USA are willing to do so. Our office produces several large bags of garbage, and we don't have that many people. I am the only person on the whole floor who uses a glass cup for tea, coffee, and water. A reusable glass cup good for my hormones, good for the environment, and also much more pleasant to drink from. I have to wash it from time to time, which some people may find it inconvenient, as it is a lot easier to fill a plastic cup with water, drink it and throw it in the garbage.
That's per year and makes for a pretty good 3 person business. Good feedback though!

According to OP, insider trading is about theft, not fairness. Given that, how is it problematic for the chef in your analogy to guess? They're not stealing, they're just acting in ways most people would consider unfair.
It doesn't and I guess I must admit I'm having trouble seeing where you're getting confused with this concept. It honestly feels like you're being deliberately obtuse. It's not the ACA that's the problem, it's the behavior of the Republican legislators regarding the ACA. It could have been any piece of legislation. It's the behavior that's the issue.

> Republicans that sought to repeal it for years and then didn't actually have any real policy ideas to replace it when they took control in 2016, exemplifying their bad-faith approach to politics?

Read that quote. Now read it again. It fully and clearly explains the issue without naming the ACA. That's because the fact that the behavior was bought to light by the ACA is irrelevant. The ACA isn't the problem, the behavior is. "It" in that quote could be any piece of legislation and the behavior would still be troubling. Does that help you see? Do you finally understand?

That's a good point. I think it's hard to definitively know the best way to resolve issues like this without an actual platform to test it on.

One point that I wasn't able to fit into the article is that this idea isn't a homerun. There are lots of difficult things to figure out. I just think that it's hard to find a problem more deserving of solving, and right now we have our best minds solving the problem of how to spy on people better instead.
It depends on your industry and customer base.

Well, you do what I do with any electronics I create, place it on some ventilated area where fire can't spread, have long cables with switches far from the equipment, do any work with power off (after waiting for any capacitor discharge), and wait for the "tshhhhh" every so often.

After it is well tested (measuring temperatures is hard, but doable) and you are confident it works, you can use it normally.
The smart hedge funds' edge is pervasive but small. And there are a lot of dumb hedge funds! (Also a lot of scheming hedge funds that are fee maximizers, not investment-return maximizers.)

> The Kitty Genovese story is a myth?

Worse than a myth: It's an example of something I half-jokingly call "Philosophically True" because it's something repeated and believed in order to bolster a philosophical position, such that it has a truth value even if it's factually wrong because some people are just that resistant to changing their minds. If you want to believe that people are basically shit and have no redeeming value and will watch a woman get killed in full view without doing anything, the usual story appeals to you, and people saying it's factually wrong won't really sway you.

Another example is how the tabula rasa idea shapes some kinds of moral philosophy: If you believe that external cultural indoctrination is absolutely required for people to develop a moral sense, you have to believe that people are blank slates at birth. This is not true, in that even toddlers have a sense of fairness [1], but if there's an innate morality, well, your favored mode of cultural indoctrination is less important and we can't have that, can we?

Amusingly enough, all of the low-level hardware access stuff in hakchi2 seems to be done through Windows ports of various Linux-based libraries and tools. The Windows drivers are just there to emulate the normal Linux APIs for low-level USB access. In principle, it would be possible to just chop out all the layers of emulation and drop in the original Linux USB access library using the actual Linux APIs (compiled as a Wine-style DLL so the Windows code could use it) and everything should work fine.
Shouldn't elite universities already be independent? The Ivy Leagues for instance have stupidly large endowment funds for one for that exact purpose! They don't seem to be using them in "burn happy" ways either like free tuition to all or funding large ammounts into their own research funding.

It could be pathological greed of getting more than they have ability or desire to spend - particularly if it is their job to gain more.

It would make sense for connections to be worth more than mere money per say and the donations are proxies/symbolic.

That is putting aside suspicion agendas against universities that have existed since students protested the war.
One of the biggest challenges with mapping house numbers is simply getting to that street to begin with. It takes a volunteer making an effort to go to various parts of town that he/she doedn't normally go to, since most neighbourhoods don't have their own local mappers interested in adding house numbers.

Once someone has made that effort, then it isn't too much extra effort to do all the house numbers. So, no need to restrict oneself to the middle of the range.

OSMAnd's address search feature already allows you to choose from among the house numbers that do exist for a street, even if the whole street isn't mapped, so it is often easy to navigate to the general ballpark of your destination.

As others have noted, electric flights require a major breakthrough in the battery technology. Here are energy density numbers for gasoline, jet fuel, and lithium-ion batteries:

Gas and jet fuel specific energy density ~= 45 MJ/kg;

Lithium-ion specific energy density < 1 MJ/kg

Even worse, a jet engine is much better at generating power. A modern high-bypass turbofan engine can generate 10 kW/kg whereas an electric motor is around 1 kW/kg.

In short we need much better batteries and much lighter motors. This is not going to happen anytime soon. A more reasonable option is to create carbon-neutral fuels (biofuels, carbon sequestration, etc.).

Run for office on a platform to make train fares cheaper and you will probably win. The only other thing to factor in is car payment, insurance, tax/reg but you probably have a car anyway so that evens out in the end in my opinion. The only other factor would be less stress due to the fixed train commute vs car. But since trains are packed it sounds like prices are too low even though they are unreasonable... I guess an alternative would be flex time and work from home options so you don't have to commute in each day.
