I'm having trouble visualizing exactly how this works from the text, but it sounds like a total nightmare. Some sort of complicated list of steps for transferring control screens between different stations on the ship, and it's not clear why or when you do this at all.

I'm guessing the Navy doesn't spend a lot of time on UI/UX, which is ironic since these long, high-stress shifts with lives on the line is exactly where it's needed most. I can't imagine a worse solution than a bunch of poorly designed, unintuitive screens being transferred all over the ship in a chaotic situation.
It's just too good - We have blamed Russia for using our platforms to elect someone. Now Russia is telling our platforms to block certain content otherwise they will consider it interference. The Cold War never ended did it?
The funny thing about this is that everyone knew this talk was happening, and that it was going to be batshit; it was a hot Slack topic for a day a few weeks ago, and the day of the talk, people were excitedly talking about making to that talk so they could gape and heckle.

I don't know precisely what happened to change this from comedy to controversy, but it definitely started with JP Aumasson's livetweet of the presentation going viral. So I guess I blame twitter.

I'm happy to discuss this stuff, but I think the conversation will be more pleasant if you avoid the snark, and maybe if you're a bit more willing to entertain the possibility that someone who's spent their career studying a subject might have spotted things about it that you haven't recognized yet.

In this particular case, my impression is that (like the paper's author) you haven't understood the core of the objection: that the non-zero field outside of the gap between the plates is important. In your derivation, you only address the exterior field long enough to say that it "quickly drops to zero". But we know that the electric potential far from the (finite!) plates approaches zero, even though it is high at the positive plate. So it's clear that even if the field outside is relatively small, its integral is not negligible: it adds up to exactly enough to cancel out all of the speed gained by an ion that started out exactly between the plates.

If you're really determined on this, I can type up a sketch of the full calculation for a pair of circular plates. But the energy considerations ought to be enough to show what the ultimate result will be. (And, to be clear, I'm not even looking at pairs of charged particles with different masses: it doesn't even require that level of analysis. This is true for any one charged particle considered on its own.)
Perhaps (though I've seen disputes of that), but since we're talking about a Western, Educated, Industrialized, Rich, Democracy country's history, it still is not an explanation for why this generation's elite's children would be pretending they're poor, instead of showing off their status with conspicuous consumption (as many previous generations have).
I wrote a paper on this a number of years ago. Here were my primary sources:

I believe the second depends on the first.
> MOSCOW (Reuters) - Russia’s state communications watchdog said on Sunday it had asked Google (GOOGL.O) to stop advertising “illegal mass events” on its YouTube video platform.

> Tens of thousands of Russians staged what observers called the country’s biggest political protest for eight years on Saturday, defying a crackdown to demand free elections to Moscow’s city legislature.

> The watchdog, Roscomnadzor, said Russia would consider it interference in its sovereign affairs and a hostile influence should Google fails to respond to the request.

If Google still follows "Don't be evil", it will respond with the equivalent of a middle finger. I hope someone there still thinks Enlightenment values are more important than kowtowing to a repressive government.

Try without a catch is fairly common and IMO quite fine when it's not the current method's job to deal with an error but it is its job to clean up state or some resources.

async showImage() {
this.showLoadingSpinner = true
try {
this.imageData = await fetchImageData()
} finally {
this.showLoadingSpinner = false
}
}

There might be a parent class/component/whatever that deals with errors and shows them to the user. The image component is responsible for showing the loading spinner and it shouldn't be left spinning if there's an error.

now m sure many people will say no but imo YES it is hard to customize. problem i faced with django is, if you go with defaults, it is pretty easy. but once you start customizing, you end up overriding lot of methods. so much DRY & magic. you can't code without api doc. for some people it may work but i don't like magic at all. i have seen lot of bad django code in production. people just copy paste from stack over flow without understanding and make requirement work.

And this is why amigo you should try Flask. Its simplicity will blow your mind.

I really think that nowadays touchscreens are becoming the cheap option. To me when I see a machine with custom designed button I know they had to do some mechanical design, whereas a flat touch screen just says "we slapped a tablet there and hacked an interface on android".

Okay, that's actually great to know. Thanks!
Here in Panama, many years ago Nestle became the main customer of tomato growers, and then through aggressive PR managed to make their canned tomato sauce into some sort of staple ingredient. There are at least three teams in this game, the farmers, the consumers and the intermediaries. One of them won.

I think this shows how there is some naivete combined with economic need that makes it easy for corporations to drive farmers against their own interests. Commoditization and systemic effects are completely ignored by people who desperately want economic certainty, no matter the precedent. In this free market, one day peppers are scarce and expensive, then the next season peppers are rotting because not enough people buy them. And land continues to steadily degrade under monoculture and animal husbandry.

When the free trade agreement with the US was signed cattle farmers thought they would be exporting meat to the US. Nature be damned. Meat is more expensive, there is meat from the US in the supermarket shelves, drought after drought makes it hard for small cattle farmers to subsist (unless they get into money laundry), and the Darien rain forest is being destroyed.

But listen to the economists. Nordhaus got the Nobel prize telling us how 3.5 degrees by 2100 is OK. Silly physicists and ecologists can't understand the magic of money.
Man for something like the main controls you would expect it to be manual.

I'm not sure the division is that strong. Years ago, I repeatedly saw a talk from a wellish known academic about "compressed" SMS messages that were simply a prearranged code. This was shortly before text messages became very cheap, wireless networking became much more common, and phone processors were in the process of becoming much more powerful.

Then there was the professor pushing their "Lego" model of network protocol development, whose example was encryption and compression blocks.

There's less money in academia, but just as much publicity.

Transferring controls between stations seems to have obvious utility if you consider the desire to relieve sailors without removing others from their stations. Give the helmsman a bathroom break by transferring the controls to another's station rather than having the people move to the controls.

The whole splitting of throttle/steering controls seems a bit odd to me however. I can't imagine a situation where I was at the helm and didn't want the throttle at my command as well.

I have knobs on the climate control on my car, but I still need to look at the screen. The problem is the knobs have no stops so I still need to look down to figure out what they're set to after they update the electronic display. On my old vehicle I knew the whole way to the left was fan blowing on feet, whole way to the right was defroster, and the 2 or 3 clicks in between were different settings of those extremes. Now I have no idea where it ends up when I spin the dial.
I read some study somewhere, which says eating meat makes you more sexually attractive and your features are developed better if you eat meat.

If there the case, I don't think you can convince people to not eat meat because it's like telling them to stop using makeup or stop making efforts to become mor handsome/beautiful
Shouldn't they do a bit of research instead? Like, research whether the people attacking your company/employee/policy are actually customers who'd have an impact on your business if you ignored them? The problem with a lot of social media controversies is that no one actually asks whether the people complaining are actually representative of either the majority of the population or the userbase for the affected service or company. In a lot of cases, I suspect if they did ask that, they'd realise that a few people getting annoyed online can be safely ignored and that doing so may earn you more not less business. Or not change a thing.
When reading these kind of articles it always strikes me as odd that we had such a huge problem to stabilize systems running on as little as a few MHz and now we have GHz machines that are relatively solid performers. The first time I built a system with a base clock above 16MHz it took all kinds of rituals to keep the system running good enough to get some use out of it.

How to Provide Great Feedback When You're Not in Charge (2016)
Isn’t it pretty common policy for the US et al to promote pro democracy protests and politicians in other countries? If it did come from state backed information sources I could see some legitimacy to the claim but I doubt that’s the only thing they mean.

As always there will be tons of misdirection to hide the sources and overstating of the impact of foreign boogiemen for political points and justification of new information controls. It’s a tactic as old as politics.
While this is good advice in general, this literally applies to every performance car (and even every car period). The Model 3 isn't unique in benefitting from better tires any more than a Golf R.

Also, the A/S 3+ is an obvious compromise for people that don't want to rotate their tires seasonally. If you're going to recommend tires for performance, the PS4S is a good choice and then get a separate set of tires for winter. In other words if you think the tires make a difference like you wrote, you're selling yourself short driving on all season tires. Do yourself a favor and buy a set of summer tires if you're serious about how your car performs.
Correct. For one, it should be mandatory that care be taken that guns not be stolen. Locked up in safes when possible or otherwise attended to and not left lying around. Secondly, a missing gun should be reported immediately. Like I said, punishment ramps up after multiple offense. If it happens once, call it a fluke and fine $100 or whatever. If it happens twice you're being careless. If it happens more, you are probably a trafficker and should be prosecuted and lose your right to own guns. This kind of rule will affect very, very few people and hopefully zero responsible owners.

So, here's a question: are we actually sure that self-driving cars are easier than just building rail systems? In other words, instead of making self-driving cars able to handle more variable environments, just making the driving environment less variable (e.g. with elevated trains or subways)? At one time, it seemed self-evident that it would be easier to get the AI working, and then you could just replicate that software at almost no cost and there you are. But, the more time that passes (and the more resources that get put into self-driving cars), the more I wonder if it's not actually true that self-driving cars are easier than just making a different transit system (subways and elevated trains being two that we already know how to make).

> One of CNN's legal analysts said in a tweet [0] that he can't recall hearing of any successful suicides happening in the prison where Epstein was detained.

We need to be clear how they define suicide, which may not include all self-inflicted death.
As another person said, its more about being "out of sight, out of mind". But the biggest component is cost and availability. Large scale farming (unsustainable over the long term) with a single crop per season and minimal rotation allowed for huge crop yields over the short term which drove prices down. At this point the majority of consumers do not want to pay more than they've become accustomed to paying for any fruits or vegetables.

Sustainable farming costs more in the short term. Over the long term it is the only reasonable way to farm.

The book "Lentil Underground" by Liz Carlisle was a great read on this topic.
Could you elaborate on how you planned and executed the transition to academia? Your profile mentions that you lecture in fluid mechanics. Very curious about what skills/knowledge you could take from your engineering experience to your teaching.
This is different. The issue here wasn’t the use of a general-purpose device itself but that the device they used (a touchscreen) wasn’t the best fit for the task at hand. Even worse, multiple screens were able to control the ship at the same time which to me seems to be the root cause of the accident. A single touchscreen still wouldn’t have been ideal, but it would’ve still prevented the accident IMO.

In the case of using Xbox controllers it’s actually a great idea - these controllers were designed & refined over decades of intensive use by all kinds of people around the world - you wouldn’t be able to do better even if you tried with a custom design. There are obvious concerns regarding reliability of the hardware, but the design itself is in my opinion flawless.

It's one thing to offer the wires, it's another to speak over them. If you were meaning to draw an equivalency it's not working out.
The answer is so simple it's brilliant: you need a permission from the local police in order to organize a protest on a specific location at a specific time. In most of the cases, that works fine.

In a small number of cases when the authorities really don't want you to organize a protest, they'll keep denying you one location after the other using bullshit excuses until the date when the protest is set to happen. Then they can crack it down for "unlawful assembly".

Note that I'm not from Russia, but I am from a country that looks up to Russia for some forsaken reason and we have experienced protests getting killed in this fashion.
Is this a serious question?

Even if one ignores the obvious Russia-specific answer, there are plenty of reasons for a protest to be illegal in more western states. Normally it would be illegal to assemble on private land without permission, for example. And there are often laws requiring protests to eg seek permission for a planned route and stick to it (though these may not necessarily be enforced).

All you need to understand is that they haven't. Assuming Apple is still a sound and rational company pursuing a similar line of business, that should speak volumes to you.
Also because the people paying for the system aren’t the ones that will end up using it day to day. The system looks nice enough for the bean counters to approve it based on looks without soliciting actual user feedback (partly because those users are way lower down the food chain but also because of the mindset of the bean counters - they see it looks nice from their perspective but aren’t aware of the benefit of user testing).

I do think we all share some blame. We live in a democracy (no matter how flawed) and we bear some of the burden of the decisions of society as a whole.

The answer to these problems however isn't just saying "everyone stop eating tomatoes in the winter." You know full well that tomatoes grown in the summer are grown using the same shit, they can just source them from somewhere a little bit further north.

Why is it that I can go to the grocery store and see two different types of tomatoes: one type is cheaper and is killing the planet and the other is more expensive but safe for the environment? I have the means and the knowledge to buy the more expensive one but we can't expect that someone living paycheck to paycheck is going to be willing or even able to do the same. They aren't the ones to blame here.

I do agree that we can't expect someone else to solve this problem for us. We need collective action to demand significant regulation and change to the economic system. Scolding individual people for making rational economic decisions when they have a boot on their neck isn't going to fix anything.

I think you are overstating the opportunity here. Unit economics of scalable food delivery do not support small towns.

Scale requires sales reps to sign restaurants, account managers to maintain the relationships with the restaurants, local operations people to recruit, induct, clothe and support the delivery guys, local marketing managers to get the initial userbase.

And that's not even considering the sprawling single-center infrastructure of smaller towns, with most affluent folk that could in theory order takeout every day living outside the immediate center of the town.

You maximize efficiency (cost per order, or in other words how many orders per hour a salaried employee can deliver, or in other words how little you can pay a non-salaried 100% commission-based delivery partner while they still maintain hourly earnings they deem acceptable) by increasing the pace at which deliveries are made by any single courier.

A dense population and a uniform distribution of popular restaurants will result in a courier going point A to B, B to C, C to D. Each node represents both a restaurant and the next delivery location.

A typical small town infrastructure would result in the delivery person going A->B, B->A, A->C, C->A, A->D, D->A. The town's only two restaurants are located in A, whereas B, C and D are delivery destinations. That's double the marginal cost per order.
