Not a physicist, but afaik you are right. If you go with the speed of light (or close enough), your travel time goes to zero. It is common misconception that to “reach the stars” you have to spend a couple of lives. In fact, you can get there before you finish your sandwich.

This makes me think of lone sad CMB photons, who accidentally stop by hitting an atom and cannot even recognize a tiny bit of the universe they remembered since. A spark moment, and they lost everything to billions of years.
> But this is where paradoxes come in because the black hole, stationary from in its frame of reference, would still experience 26,000 years and not see you arrive until then.

Special relativity solves this fine (there is no paradox in it for that particular thought experiment), no need to involve general relativity. There is nothing paradoxical about the observer near the center of the galaxy not seeing you until you are near, because you are traveling at speed almost as great as the speed of the information carrier (the light you emit if we are talking about space, or the sound you make if we are talking about something on Earth). So you actually do not even need relativity to explain the "they do not see us coming". You do need relativity to explain the fact that to you all of this took only a blink of an eye.
"An interesting solution, it would definitely prompt the user to understand what the device is trying to do."

But then it could simply wait for the user to enter the password (1), then read it by sniffing the traffic from the keyboard and store it internally for later use, since it's all in clear ad it cannot be encrypted before entering the machine unless most (all) USB consumer hardware get some heavy modifications.

1- very simple algorithm: store in the internal flash memory whatever the user enters between connecting the keyboard and hitting the 2nd enter key; if it's mostly the same words, then it's very likely an user/password pair.

"But I'm sure that it's extremely hard to prevent something malicious, once it has physical access to a port on your computer... "

Very true. Malicious plug in hardware was just a matter of time; we badly need some active protection for these things, or it would be a mess. This is the perfect weapon in the hands of people with a thing for vandalism, I hope mainstream media won't cover that story.
There's no way of knowing from the outside, but this seems relevant: "For this article, WIRED spoke with 47 current and former Google employees. Most of them requested anonymity."
Germany has encountered resistance both to additional onshore wind projects and to the necessary transmission infrastructure for moving onshore wind power around the country:

https://www.cleanenergywire.org/factsheets/fighting-windmill...

https://www.dw.com/en/germany-protesters-oppose-suedlink-win...

There is less resistance to offshore wind projects and to small scale distributed solar. Both of these generating resources are more expensive than onshore wind farms.

Even in the matter of distributed solar, note that the peak installation rate was back in 2012:

https://en.wikipedia.org/wiki/Solar_power_in_Germany#Generat...

Germany not only installed a lot of a particularly expensive kind of renewable capacity (distributed solar). It did most of that installation some time ago when it was even more expensive to install. And it did so in a very sunlight-constrained climate, so each kilowatt of capacity generates much less energy than in Italy, Spain, or the US. Since industry threatened to just relocate if higher electricity costs were passed on, residential and commercial electricity customers have borne the financial brunt of the renewable buildout while heavy industry was spared.

The UK did better by phasing out coal in favor of gas faster than Germany and not installing significant solar capacity until the hardware had become much cheaper. The UK's renewable additions were almost exclusively wind until 2011. The UK started deploying significant solar several years later than Germany:

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

Between deliberately choosing to pioneer solar PV installations in a low-sun country, phasing out nuclear power, and acting to placate the powerful domestic coal lobby, Germany has really spent a lot of money to accomplish a very modest degree of decarbonization.

From my understanding, TSA security isn't customs, so it isn't a constitution suspended zone.
Turkmenistan since independence has been a reclusive benevolent welfare state. They have universal basic income there, one of a small number of countries and states.

They are compared to North Korea but it's not a fair comparison since they threaten no one and their people are not oppressed. They are restricted, and strongly encouraged to pursue traditional tribal activities and eschew the western world. But not oppressed, despite outside claims.

The capital city's architecture is among the most bizarre and fantastic in the world and worth a visit if you can get in, which is very hard. You have to be invited to visit. Some tourism agencies can arrange this but it's not for the average traveler.
Recycling Is in Crisis. Could These Innovations Be the Answer?
And also - how it will affect TSA Precheck-ers who currently does not need to pull out laptops?
Even if it gets fixed, how would TSA know that? If TSA doesn't check at all, then the "solution" is relying on people following a rule that has no enforcement.

How many people are going to actually read these articles to know which models are affected? How many people are going to remember the articles when it's time for them to go to the airport? How many people are simply going to ignore the rule because their MBP is their primary computer and would rather not go without it?

Can they afford to have some people or most people defying the ban? Because as it stands, it's impossible to tell how many people are just going to voluntarily follow a rule with (close to) zero enforcement....unless they actually enforce it
To add to the other comments that are attempting to correct you (although the downvotes seem unwarranted): the misconception you are presenting is one of the most common ones I see in students when teaching relativity. The event did happen long time ago and the fact that time and space are relative have nothing to do with the fact that it takes us some time to see/hear that an event has happened.

Sprawl might be reversing. The younger generation are having smaller families and don't like driving. This means less "big house" buying and shorter commutes. They are more open to the idea of crowding toward the center of a city. The Great Recession taught them how to avoid big expenditures.
Not quite as bad as it sounds.

> Laptops that have replaced batteries won’t be impacted

Edit: re how to check, in theory you could prove it was fixed by showing the service receipt from Apple. In practice, I have no idea what would happen. But I feel like you'd get through if you showed up with a printed receipt taped to your laptop.

I can almost guarantee the TSA will invest zero dollars or time into deciding which MacBooks are okay. This is Apple's problem to solve. Zero time, money or attention from the TSA or the airlines will be invested. If the FAA bans any Macbooks, all "Apple looking thingies" will be effectively banned.

Advice: Buy a Dell sticker to cover the apple logo on your MacBook. Or some similarly silly thing like an "Apple Store FAA compliant sticker" program. (I'm linking back to this comment later when it happens :)

When I was a kid, Metallica was widely seen as completely crazy (this is the Kill 'Em All to Master of Puppets era). "Big kids" who listened to Metallica were vaguely threatening and best avoided. Now even those early thrash monsters are considered to be classic rock. Metallica is eminently respectable.

There is some extreme metal that will never be mainstream or widely listened to but that mainly comes down to the amount of work that's required to listen to it (Deathspell Omega) or the purely misanthropic production quality (Darkthrone's Panzerfaust, an album I adore). This sort of music is "shocking" in the sense that most people assume bands make music because they actually want people to listen to it.
Along with the hassle of opening the laptop, powering it on, and clicking About This Mac; you would have the security issue of entering your password while surrounded by other people and cameras. None of the verification options seem very appealing.
I’d be curious how it compares to Universal Studios Hollywood. Personal observation is that Universal Studios has gotten better, faster (with recent addition of Harry Potter area) and is more fun/interesting for the older crowd. If you had to choose one or the other because both are expensive then Universal Studios seems like a better option unless you have very young kids.
The kids not familiar with it would mess it up?

I got a 3900X and the Asus X570 workstation board to make sure I'd be able to support ECC RAM within basically a couple hours after I made that post. My needs are video encoding and virtualization setups needing lots of cores so this makes a lot more sense for me than any comparable Intel setup for my money. I'm slightly cheaping out by not going with ECC RAM but in the era of catering to overclocking gamers over professionals I'd rather pay more for a workstation board.

Most people DO NOT give a shit about trout for example

I'm a trout fisherman and think they're an insanely beautiful species. When I flew into Montana my trout stamp was like $150... non-trivial amount but absolutely worth it.
I'm also interested. And adding to the question: Is it possible that this particular flare-up may be a forward echo of such an event? I.e. have we observed this happen before in other parts of the Universe?

Surprise! The laws of economics still apply to you, even if you're a company with a great brand like Disney and Apple.
X-class flares from our sun are 10E32 or so ergs. The black hole flares were roughly 10E35 ergs, about a thousand times more energetic but they are about a billion times farther away than our sun. Apply N^2 law and . . .

The amount of radiation you received from the Sagittarius flares is almost indescribably tiny. Many, many orders of magnitude less than the cosmic ray background radiation that we already live with. If you didn't have a sensor pointed right at the BH, you wouldn't be able to distinguish it from the noise.

You wouldn't say that about an aftermarket for, say, vintage car parts, would you?

To be specific, if you buy yourself an original VW bus, you won't be on your own when you try to service it.

Amiga just might be the VW bus of retro computers (probably Commodore deserves this title better, but the analogy works the same way). It'll be alive for as long as the feelings associated with it are understood.
Excellent answer. To which I'll add:

IFF standards. In today's world it would be an unthinkably open approach taken by open source only. Even more surprising it came from a joint venture between Commodore Amiga and EA! Every single graphics program understood, and via datatypes understood in a standard way, IFF graphics. Saving, processing or reading. They were so prevalent and expected that you would be hurting your chances to release something with a propriety only format. Same went for sound and no end of other things. Had the Amiga thrived there'd no doubt have been an IFF in place of many of the multimedia formats. With a standard OS level library call to decode them, etc.

The conciseness of approach, necessary in a system providing proper multi-tasking in 256K, meant all the services other platforms placed at least partially in the .exe were usually in the OS. There were system libraries you could rely on without the absurd version dependent dll hell of windows. I'm sure had the Amiga persisted there'd be some version annoyance, but I can't imagine it reaching the stupidity of now.

Windows had far more than glue code in the exe. If you needed to use a file requester, accept messages, have a window that could be resized etc there was tons of unique OS related code in the exe for all that etc etc. Update the OS and unless you update the source and rebuild the exe it will clearly and obviously be of the previous Windows release. Or as was so often the case buy the latest office and the look is clearly of the next, unreleased Windows. Amiga had it such that all that rubbish was nearly all external. Set up your structures, call the API, get woken up when there's something you need to care about. If you updated OS, all your window chrome, file requesters etc, would be of the new OS. No ridiculous dependencies on v 3.2.152 of MSVC.dll, and 3.3.x not being acceptable, meaning you end up with 12 different installed versions etc.

Only apps doing something clever - like CygnusEd with its hand written assembler scrolling that remains, 30 years later, my benchmark for "fast and smooth enough" editor scrolling. Essentially nothing has yet matched it, though Sublime is probably closest just without smooth scrolling. It was really difficult to come to accept - in some sense I still haven't - that I had to do so much of this OS housekeeping for myself each and every time, in every application for other platforms. I often used to wonder what Windows was, in fact, adding as it always seemed like I was doing everything myself. I gave up complete on Windows programming pretty quickly as a result. :)

AmigaDOS may have been a bit of a last minute, ugly addon, but in use it felt like a lightweight single user *nix. Proper filenames, priorities, comments, proper scripting and ARexx if you needed additional integration. Sure, it was far happier on a HDD, but what aside from DOS - more a program loader than OS - wasn't? :)
Same here. It seems the websites that show up top are become more and more spammy and less relevant to my query. I keep seeing all sorts of one sentence hipster 2.0 sites that want me to believe they are a credible source of information.
To me, "we get it" sounds friendlier than ”we understand."
Yes, they can afford it. The purpose is just to reduce risk. The rule doesn't need to be, and I'm sure it wasn't intend to be, foolproof.

Can it? Disneyland continues to increase prices. Galaxy's Edge is basically one big store hocking overpriced trinkets.

I used to go to Disneyland every week for lunch in high school (I've always lived about 15 minutes from it). Business meetings were casually scheduled and held at the Blue Bayou until the yearly pass pricing doubled at the turn of the millennium.

Now, I can't even rationalize going for fun, much less purchasing food in the park. Inflation, price hikes and taxation has steadily priced many things out of affordability, in California.

YouTube was tricky for me too. Because so many tutorials are on youtube it’s hard to ban it. And you watch one it’s no longer blocked at least on that tab. Get “distract free tube” or something like that on chrome/Firefox. It gets rid of the side bar, trending, suggestions etc. basically everything but the video.

It doesn’t solve the deeper problem but it turns a time suck website into a productive one.

> Yet another milestone of the integration plan of ROOT with the Jupyter technology has been reached: ROOT now offers a Jupyter kernel! You can try it already now.

> ROOT is the 54th entry in this list and this is pretty cool. Now not only the PyROOT, the ROOT Python bindings, are integrated with notebooks but it's also possible to express your data mining in C++ within a notebook, taking advantage of all the powerful features of ROOT - plotting (now also interactive thanks to (Javascript ROOT](https://root.cern.ch/js/)), multivariate analysis, linear algebra, I/O and reflection: all available within a notebook.

I like to play Bingo with comments on science stories:

- "it was actually X thousand years ago"

- "it's actually false color, why can't we see what it really looks like"

- "surely this means quantum FTL communication works"

- something casually eugenic

and recently, with the Mauna Kea stories, there's a guaranteed "who do these bozos think they are, science is more important than anything"
Universities should collaborate on creating (or improving existing) open peer review and publishing platform. It can be based on MIT's PubPub[1] or created from scratch. Adding more features like in Authorea[2] and Overleaf[3]. Since PubPub sources are on GitHub[4], it is easy to improve today and now. Enhancing the existing infrastructure around arXiv and bioArXiv will help too. Today many universities trying to pursue their objectives or creating their platforms. But the complexity of the task requires a united effort.

You have to fund that somehow so ... prices go up! Real estate isn't infinite, but Disney World in Florida is expanding now more than ever. If they ever have to build a new set of parks elsewhere, real estate prices are going to be ridiculous, and you have to buy it somehow so ... prices go up!

I don't see how increasing supply brings prices down at Disney - they'll hike the price now to fund it, then they'll hike prices again to control attendance.

Buy Disney stock.
To everyone saying “how will they enforce this?” the answer is the same as everything else. If you take a gun on a plane and get through TSA with it, you still committed a felony. If you then use the gun and put a hole in the plane, you’ll be personally liable for that.

If you take an explody battery on a plane and it explodes, the liability is on you.

The TSA might ask you if your laptop has an unsafe battery. That will probably be the extent of the enforcement. Now you know that you could be committing a crime if you haven’t checked it.
Well, yes, and there are lots of other things Google can do because they have so much money, like their various research projects.

But remember that Google+ was a company-wide initiative intended to compete with Facebook, which is kind of a big deal. Yes, they had lots of money to throw at it, but it was for a purpose.

The internal version was originally for testing. (Also, the business version of Google+ is still a product as part of G suite.)
Well ideas on the left of the political spectrum generally demand larger more centralized governments, because it's required to implement heavy-handed government interventions; whereas, ideas on the right, traditionally, are about smaller government and therefore tend to have much less of a centralized government.

Note I say ideas here, because the reality is e.g. the republicans in the US are for the most part big government politicans despite being on the right, but that seems more a bastardization of the traditional right, which historically is about smaller government.

So generally speaking, because left wing political ideas tend to involve big government, it means that centralization is generally more extensive in left wing governments, and I would argue thus left wing governments are more liable to be autocratic.
Not at all. We’d just grow vegetables in the Northeast where’s there’s water. We would be screwed with unaffordable nuts and citrus though.

Have you not seen the problems that have popped up due to the ad blocking arms race?
Nothing. Except your desire not to commit a crime of taking banned items on a plane.
I actually took an 10 inch screwdriver on to a flight accidently. When I was unpacking at the hotel I was like "how the F did this get past the security check?"

Another time I was running late for my flight and forgot to empty my 16oz water bottle. After my bag went through the scanner I realized my mistake and told the TSA agent about it. He uncapped the bottle, swirrled the water around, sniffed it, and then handed me back 16 ounces of water and said not to worry about it.

So yeah, I have minimal expectation TSA will catch this.

Now UK airport security might handle it. I've been specifically asked if my laptop has been damaged, is swelling or has been recently repaired. I assume if you answer yes to any of those questions your device is banned from flying.

Has anyone found any information about how to prove you've had the battery replaced?

My battery started swelling a couple months before the recall. I was in Brazil at the time so I had to have it replaced by a third-party repair shop.
