542354234235··on Cherenkov Radiation - traveling faster than light
I am willing to be wrong on this, as I’m not a physicist and I’m going from memory. But I thought that nothing could travel faster than light because spacetime is interconnected. So as something travels “faster” it is simply moving more through spatial dimensions and less through time dimension. Light travels completely through spatial dimensions, leaving no movement through time, which is why nothing can travel “faster” than that.

Like if I am walking North-East, I can change direction and travel in a more northerly direction or more easterly direction, but if I’m traveling North, I can’t change directions to travel any more in the northerly direction. I’m already traveling 100% in the northerly direction.

This feels like a deliberate straw man. I never said it ruined my entire experience. Also, you go on to talk about mundane everyday interactions. I think if you flew to a different continent to do a multi-day hike meant to be a once in a lifetime thing deep in the Peruvian mountains, and someone was blasting music, you might be bothered. But your inability to empathize at all with another person makes me suspect you might just be a different variant of who we are talking about.
542354234235··on The largest electric aircraft just flew [video]
Landing weight limits are less than takeoff limits because of the extreme stress it puts on the landing gear. This is why planes that have an issue right after takeoff often need to dump tens of thousands of gallons of fuel before they can land.

>Aircraft have two main types of weight limits: the maximum takeoff weight is composed of dry operating weight (DOW) plus payload (passengers and cargo), collectively the zero fuel weight (ZFW), plus the trip fuel, contingency, alternate, final reserve and the block fuel (taxi fuel), and the maximum structural landing weight, with the maximum structural landing weight almost always being the lower of the two. This allows an aircraft on a normal, routine flight to take off at a higher weight, consume fuel en route, and arrive at a lower weight. [0]

>If you overpower a signal, is there a difference?

Yes, obviously. Losing signal on your GPS unit, and having your GPS unit tell you that you are in a different position than you actually are, are two very different things.

Also, since other aircraft reported GPS issues, that is evidence that would speak to jamming or spoofing. All three other aircraft reported a loss of GPS, not inaccurate GPS. Coverups are real, government conspiracies are real. But the completely evidenceless “I’m just saying…” or “isn’t it weird…” or “I’m just asking questions” is tiresome.

You can order drinks at a bar and on an airplane, what's your point? Do you go out to eat specifically to talk to cashiers? If i want fine dining, being served is part of the experience. But if I want a good bowl of ramen, I can't see how using a tablet is some sort of deal breaking issue. What vital experience do you get giving a regular food order to a cashier?
542354234235··on And then the men with guns tell you to do it anyway
Sure, the idea of revenge is attractive to me as well. But I really don't want the legal system to operate at the level of my base emotional desires. If a crime is bad enough that there should be no second chance, segregate them from society safely until they die. I don't see how the justice system hurting/harming/torturing people does anything other than normalize hurting others when you feel wronged, and therefore normalizing more criminal violence.
542354234235··on And then the men with guns tell you to do it anyway
But artillery barrages don't delivery 100% of their payload in the first round. If your building is hit with the first round, yes you'll be dead. But there will be a second, third, fourth, fifth, etc. round coming and many people could get to better, more survivable locations, before those impacted. In the book "With the Old Breed: At Peleliu and Okinawa" the author talks about being under artillery fire in an open area.

>"To be shelled by mass artillery and mortars is absolutely terrifying, but to be shelled in the open is terror compounded beyond the belief of anyone who hasn't experienced it."

It is estimated that Seoul would have 2-4 minutes of warning of an NK barrage due to the artillery shell flight time. Having 2 to 4 minutes to get anywhere other than an open area is valuable.

A NK artillery barrage on Seoul would be horrific and devastating but it wouldn't kill everyone.

> One early examination of the problem, by Bruce Bennett of the RAND Corporation, finds that circa 1995 the KPA may have been capable of firing as many as 200,000 long-range rounds into South Korea on the first day of a conflict—and that even a short 3-to-5-minute artillery barrage into the Seoul metro area could cause as many as 7,500 civilian casualties—with the total fatalities rising much higher if North Korea continued the attack. An analysis from 2012 by Roger Cavazos finds that a North Korean artillery attack on Seoul could produce around 30,000 fatalities. And a recent study by researchers at RAND finds that an hour-long artillery barrage on Seoul would produce between 87,600 and 130,000 casualties, of which between 6,620 and 10,680 would be fatalities—with many more fatalities to come if the artillery bombardment continued.

The issue is that with a sample size of one (or three), then it is basically bad luck. If you get a bad unit (or a good unit) it doesn't really tell you much how reliable the other 100,000+ units are and how reliable the brand is. If you have a product get damaged during delivery, it doesn't really tell you much how reliable the other 100,000+ deliveries are.

But most people have had a problem with some product they purchased and a company that stands by things and gives no questions asked support is very valuable.

542354234235··on The coolest use for the Vision Pro
But reality is never as perfect as the design. It seems to me that being able to "stand" in a rendering and look around is going to put you much closer to reality than looking at blueprints and a front elevation. So i don't think the question is "could VR and the end product be different" it is "is VR closer to the end product than other options" and I think the answer is likely, yes.
542354234235··on Which Odyssey translation wins a blind reading test?
As others have said, this is covered in the "What's the most accurate translation?" section, with examples of Textual, Poetic, and Interpretive fidelity differences.

The Emily Wilson translation begins with an extensive introduction covering the things you have to balance when doing a translation, translation choices, some faults or misleading choices she believes some other translations have made, why she made the choices she did and her reasoning and goals behind them, etc. It is well worth the read to help understand that there is no one way to be "faithful" to the original.

I've read Fagles and Wilson, so I am certainly no scholar on the subject.

I just got the X3 and i love it for all those reasons. I have a card holder wallet that it fits right onto so I have it everywhere. I am reading so much more instead of checking my phone to fill random down time. I wondered if the small size would be annoying to read on, but since page turns are so quick and easy, I have zero issues. I'm actually starting to prefer it to my Kindle for longer reading because it is so light, I can hold it longer or in more random reading positions without any hand fatigue (as minor as that is with a Kindle).

This just strikes me as the false dichotomy that there are two option; complete freedom of choice, and complete mind control that you are physically incapable of resisting. That as long as you are not physically incapable of, say turning off a video, that there is no problem. Just because you can stop using crack doesn't mean it isn't dangerously addictive. Just because you can say no to someone holding a gun to your head does not mean it isn't incredibly coercive.

Also this seems to ignore that people can be influenced or manipulated without being consciously aware of it. Like the people that say that marketing doesn’t work on them, failing to see that every interaction with the products and services they buy and use are curated in some way to influence and manipulate them.

I had the opposite happen, where I was talking to customer service and her tone was so even, and everything she was saying was so "generic optimal helpful sounding but professional" that i said to myself "oh, its an AI" and she immediately said "um sir, I'm not an AI" in a much less polished voice and it was clear she just had her customer service voice dialed in perfectly. It was definitely awkward.

I think you vastly underestimate how maintenance requirements impact how rapidly you can bring forces to the fight and how long you can keep them there. While that is exacerbated by long supply lines, it is an extremely important factor in any combat scenario.
542354234235··on OpenAI unveils its first custom chip, built by Broadcom
Those are really two different things. One is the computer vision that could be “hard coded” and the other is the image library, that would be updated regularly. Look at facial recognition. You can download and run a facial recognition LLM on your GPU that looks at a library of your personal photos. The LLM doesn’t change when it scans your photos for faces, it just writes the data associated with a “face” to whatever library. When you add a new picture, it adds that face data and compares it to the library for a match. The actual LLM never needs to change. It is the same as the one I downloaded and ran on my GPU for my photos. If it was written on chips we both bought and installed, it would work the same way.[1]

542354234235··on The Xteink X4 E-Ink Reader
You read on a phone and on a tablet, so the X4 probably isn't for you. I hate reading for long periods on LCD screens. I have to do it all day at work and I don't want to do it at home. I read on a kindle unless I really need a computer screen for photos or graphs. I am just not going to pull out my phone to read a book, so an X4 sized device makes it easier to have a book with me. Since phone reading doesn't bother you, I doubt you would get much out of an X4.

542354234235··on The 2-Year Apartment Rule
I used to be in a house that needed a dehumidifier. I bought one with a built-in pump to empty the water tank, which can be tapped into an AC drain line, sink drain, or directly outdoors, depending on your situation. You can set many of them to run constantly or when humidity is above a certain level.

If you live in a hot/humid location your HVAC is much better at dehumidification than a dehumidifier, since a dehumidifier outputs a ton of heat to operate. But in a cool/humid location, you can definitely rig up one to be decently set and forget. You still need to perform maintenance (cleaning the grill, adding a bit of white vinegar to the water tank to kill growth buildup, etc).

I actually put mine into the HVAC cabinet and used a smart plug and smart thermostat to turn on the dehumidifier and the HVAC fan to dehumidify the house. But that’s way more than you need to do for a small apartment.

>Animals generally have no qualms at all about killing or even just mutilating other animals.

Humans generally don't either. Individuals do, but as a species humans regularly kill other humans.

>invertebrates often consume their prey alive

And humans use the oh so humane factory farms.

>cats and other small predators often hunt just for the fun of it, killing but not eating their prey.

>On the more purely painful evil side, invertebrates often consume their prey alive, inflicting agonizing deaths with no issues on whatever they may be eating.

Sharks are caught en mass, the fins cut off, and the sharks dumped back into the ocean to slowly die, for shark fin soup.

Have you heard of trophy hunting? Have you seen the pictures of mountains of bison sculls for the American West?

>Plenty of vertebrates kill and consume their babies, especially when frightened.

Even in our modern "1st world" society, scared teens still abandon newborns in dumpsters. Many societies throughout history did not consider babies "real people" until a certain age because they may need to abandon them if resources were particularly scarce.

>They also often abandon old and weak members of their packs, leaving them to die of hunger or cold or similar deaths.

Maybe you should read stories of cities under siege, famines, wars, governmental collapse, etc. Humans now live nice comfy lives most of the time, unlike animals “in the wild”. Human societies that lived closer to the edge of survival made callous choices about life or death you are spared from.

"Successful" is the key. A winning lottery ticket is one of the quickest ways to get money, the hard part is the "winning". If you are smart, there are many career paths that are highly likely to be very profitable, with small risk of failure and a pretty high floor. That is not the case for starting a business. The upside is potentially much higher, but it is much less likely, and the downside is huge.

Having access to capital is much more important than smarts, which is why so many people starting businesses have generational money propping them up, or as a safety net. Even smart people are usually reliant on that family capital. Bill Gates’ parents were millionaires, Musk and his dad’s emerald mine, Thiel started his first hedge fund with a million dollars raised from “friends and family”.

Moving a six-figure Audemars Piguet or Patek Philippe watch through an airport would be much easier than the equivalent in gold or cash, even at 50% value. A watch roll with four watches in it could be the same value as 4-5 lbs of gold. If you needed something that you could cash in anywhere on the planet fairly quickly, gold would be the best option. But if you wanted max value, minimal scrutiny and had time at the other end to set up legit buyer, extremely high-end watches would be a pretty optimal option.

Or get approval for $5m, run operation for $2m and pocket the rest. Operation has provable, demonstratable effects, and the falsified payoffs are mixed in with the real ones. If people check up on you, you can point them to assets still on the books to confirm a payoff or funding for equipment. Rinse and repeat. Its just embezzlement, but in an environment where the assets are supposed to not be traceable. Rinse and repeat.
