The town’s undertaker embalms everyone who does not embalm themselves. Who embalms the undertaker?

I know Lemmy hates AI, but this actually would be a perfect use for it. The problem is the idea of what an ad is. Yes, you could try to use secondary characteristics like image color or sound normalized volume (WhyTF do youtube ads still sound 3x louder than content? are we living in cable era again?), but they would be error-prone for any content more visually intense than a podcast. They would also not capture sponsorblock content like “I love showing you all these foreign countries but what I love even more is having my internet connection secure” that match the video flow. A crowdsourced lookup table of all known ad clip fingerprints would go a long way, until ad videos themselves start being AI-generated on the fly for that sweet personalization revenue.

No, what I really want is to distill the idea of what I want to see into an AI and have it filter out what I don’t want to see for me. I know an ad when I see one, so AI can too. Pre-roll/mid-roll ads? Gone. Sponsorblock content? Gone. Like and subscribe? Skipped as if it didn’t exist. Virtual billboards on the sidelines of sporting events? Overlayed with kittens. Idiocracy banners squeezing the video from either side? Cropped and rescaled. Watermarks? Excised and content-aware-filled.

The last frontier is when the content itself is secretly an ad, imprinting upon you some idea or point of view. You’ll have to watch out for that one on your own.

Ah, I can see OP’s line of thought now:

• you have a point A’ on a plane and a random point A
• you find a midpoint B and draw a sphere around it. A and A’ are now a diameter of the sphere
• pick two random points D and C at the intersection of the plane and the sphere
• by the “triangle inscribed in a circle/sphere where one side is a diameter” rule, such a triangle must be a right triangle
• therefore both angles ACA’ and ADA’ are right angles
• thus C and D both satisfy the conditions of the initial question (with all points renamed: A=P, (C or D)=H, A’=A)
• OP never defined what a projection is, it being “4th grade math”, but one of the requirements is being unique
• C and D cannot both be the projection, therefore the initial question must be answered “false”: just because AH is perpendicular to PH doesn’t make H a projection.

I like treating posts as puzzles, figuring out thread by thread WTF they are talking about. But dear OP, let me let you know, your picture and explanation of it are completely incomprehensible to everyone else xD. The picture is not an illustration to the question but a sketch of your search for a counterexample, with all points renamed of course, but also a sphere appearing out of nowhere (for you to invoke the inscribed-triangle-rule, also mentioned nowhere). Your headline question is a non-sequitur, jumping from talking about 4D (never to be mentioned again) into a ChatGPT experiment, into demanding more education in schools. You complain about geometry being hard but also simple. The math problem itself was not even your question, yet it distracted everyone else from whatever it is you were trying to ask. If you ever want to get useful answers from people other than crazed puzzleseekers like me, you’ll need to use better communication!

In the ultimate, you’d need to do something like run a headless browser in a virtual machine, have it play out and record the entire video, then use something like AI to splice out the ad segments and distracting elements (a souped-up sponsorblock will work for a while, but eventually ads will be injected into the raw video stream at random intervals), and present the pristine finished content to you. Basically we are going to re-invent TiVo all over again xD.

In worst case, you can’t start watching until the pre-roll ad timers expire. This is how adblocking works on Twitch streams currently - you can only see a purple screen even if you block the ads.

And yes, the headless browser will need to use AI for human-like mouse movement and to solve captchas - basically whatever state-of-the-art technologies spammers and scrapers are already currently using.

Google is anticipating this future and is trying to implement and force hardware-based DRM for web video before then.

PH would be parallel to n

The question doesn’t posit that.

Spoiler alert: the image has no relation to the question, it’s just something OP picked to elicit that “3D geometry” feeling. There is a point A’, a point B, point C, and point D, but no point P or H or n.

Stripping down to a skeleton of a software is standard troubleshooting procedure. Ever had a plugin crash and consume 100% cpu? I had. Only way to sense is that fans are spinning up and page is laggy, and then look in about:performance and there it is. No one would have ever suspected that the website you’re visiting is deliberately introducing bugs in secret if it thinks you’re adblocking.

It’s a tarpit. If they simply displayed a blocked “no vids for u” message, you’d get outraged, go complain online, look for workarounds, and eventually find a bypass. If everything still works but poorly, you get annoyed, turn off your adblocker to troubleshoot, possibly blame the adblocker for being “buggy” and keep it off. Their help page solution implies they are hoping for just that. There is no “smoking gun” blocked message to go complain online about, even though it is indeed their servers that are degrading your connection on purpose in secret. Or maybe you give up and leave their ecosystem entirely, which is no big loss for them.

The proper solution is to develop an adblock that they cannot detect is blocking ads. This may require actually downloading the ad video in background, and then lying that the video has played.

it might detect those elevated stress levels [for callers] and it will automatically default going to a human being

Damn. I get ice cold emotionless during an emergency, going straight to the point of reciting location and event when calling 911. Now I will have to also remember in the back of my mind to throw in a wavering voice and a couple of shrieks maybe to have my call routed properly. What a future.

Airplane mode on Apple has two sub-toggles: wifi and bluetooth (the main toggle controls the cellular antenna). With all three toggled off, find-my does not work. The device just shows up as “offline, location unknown, last seen at…” on the map. Something to watch out for though: for some reason Apple will turn bluetooth back on after a couple days without asking, even with airplane still on. Also, an app running in background could in theory record the GPS coordinates and transmit them to home server once connection is reestablished.

dark matter isn’t connected to the expansion of space

To be double-precise (😜) both dark matter and dark energy are related to the expansion of space. What you probably meant to say is that dark energy is responsible for the accelerating rate of space expansion. Dark matter slows the rate down.

Even if there was no dark energy, the universe would still have been expanding… at first. If there was enough matter+dark matter+light, the expansion rate would slow down to a zero and reverse, resulting in a Big Crunch. But if the amount was below a critical threshold (Ω_M = 1 in this picture: https://en.wikipedia.org/wiki/File:Friedmann_universes.svg) then the rate would never slow down to exactly zero (same as a rocket on escape velocity always slows down but never returns back to Earth), and expansion would continue forever.

When you add dark energy back in, the expansion rate starts accelerating, but only when the density of dark energy is greater than the density of matter+dark matter+light. The expansion of our universe was actually decelerating until 5 billion years ago, because matter+dark matter dominated. With the right ratios, we could even have had a Big Crunch despite having dark energy.

So matter, dark matter, and dark energy don’t cause the expansion, they only gradually increase/decrease the rate it happens at. But then why did expansion happen in the first place? That’s the initial boundary condition of the universe. The Big Bang theory doesn’t explain why Big Bang happened, only how.

how individual events have zero predictive power but we have predictable patterns emerge over thousands of events

The trick is that you don’t see the interference pattern in the raw data. You see one big blob. Every popular science explanation of DCQEE fails to mention this one important fact. See my past illustration for reference. You need to separate the blob into two overlapping interference patterns manually, and you must use the quantum eraser bit to decide whether to assign each event to pattern A or pattern B. If you have already erased the bit, you cannot do the assignment.

P.S. If you going to talk about particle A and path B and whatever, it helps to post a link to the picture you are looking at.

Then you’d be surprised when you calculate the numbers!

A Falcon 9 delivers 13100kg to LEO and has 395,700kg propellant in 1st stage and 92,670kg in 2nd stage. Propellant in both is LOX/RP-1. RP-1 is basically long chains of CH2, so together they burn as:

3 O2 (3x32) + 2 CH2 (2x14) -> 2 CO2 (2x44) + 2 H2O (2x18)

Which is 2*44/(2*44+2*18) = 71% CO2. Meaning each launch makes (395700+92670)*.71 = 347 tons CO2 or 347/13.1 = 26.5 tons of CO2 per ton to orbit. A lot of it is burned in space, but I’m guessing the exhaust gases don’t reach escape velocity so they all end up in the atmosphere anyway.

As for how much a compute satellite weighs, there is a wider range of possibilities, since they don’t exist yet. This is China launching a test version of one, but it’s not yet an artifact optimized for compute per watt per kilogram that we’d imagine a supercomputer to be.

I like to imagine something like a gaming PC strapped to a portable solar panel, a true cubesat :). On online shopping I currently see a fancy gaming PC at 12.7kg with 650W, and a 600W solar panel at 12.5kg. Strap them together with duct tape, and it’s 1000/(12.7+12.5)*600 = 24kW of compute power per ton to orbit.

Something more real life is the ISS support truss. STS-119 delivered and installed S6 truss on the ISS. The 14,088kg payload included solar panels, batteries, and truss superstructure, supplying last 25% of station’s power, or 30kW. Say, double that to strap server-grade hardware and cooling on it. That’s 1000*30/(2*14088) = 1.1kW of compute per ton to orbit. A 500kg 1kW server is overkilling it, but we are being conservative here.

In my past post I’ve calculated that fossil fuel electricity on Earth makes 296g CO2 per 1 kilowatthour (using gas turbine at 60% efficiency burning 891kJ/mol methane into 1 mol CO2: 1kJ/s * 3600s / 0.6 eff / (891kJ/mol) * 44g/mol = 296g, as is the case where I live).

The CO2 payback time for a ton of duct taped gamer PC is 1000kg * 26.5kg CO2/kg / ( 24kW * 0.296kg/kW/hour) / (24*365) = 0.43 years. The CO2 payback time for a steel truss monstrosity is `1000kg * 26.5kg/kg / (1.1kW * 0.296kg/kW/hour) / (24*365) = 9.3 years.

Hey, I was pretty close!

A solar-powered computer in space could recoup the CO2 cost of its launch fuel over its lifecycle (say 10 years?) when compared to coal-fueled electricity on the ground. After that it’s free. Of course, you’d benefit more by filling up every available spot on the ground with solar arrays first! But you will eventually run out, or you might not want to do that.

If you have a megawatt solar array, you can also afford a megawatt cooling array. The size is comparable.

Closing a traffic lane on the Story Bridge for a temporary cyclist and pedestrian lane has been ruled out

Of course.

Yeah, with a Lagrange keyhole orbit past the Moon (which is what OP is asking about, not just plain escape velocity), you could park an Asteroid Belt asteroid in an orbit around the Earth. But it will be a high orbit. Not sure how low you could get it, I’m hoping a circular geostationary orbit is possible? But more likely something in the 300,000km range.

Low orbit is out of the question. Maaaybe you could park the asteroid in a highly elliptical orbit where the perigee is inside the atmosphere. The drag will circularize it if the asteroid is small enough. But not so small or weak that it burns up or breaks up before that happens. And not so big that drag takes too long and the orbit wobble makes it hit the surface. In a low Earth orbit you now only have 8km/s delta-v to deal with.

But to get the asteroid to gently touch the surface the way OP describes it, like some sort of skyhook? Is impossible short of a planet X or a rogue black hole passing even closer to the Earth than the Moon at the right moment. And whatever remains afterwards would be hard to call a surface: https://www.youtube.com/watch?v=kRlhlCWplqk

they build a new path

Hahahaha!

But seriously. They took a streetcar lane, which has been torn out and repurposed for a car lane, but is so narrow and uncomfortable to use that in modern day few cars ever use it. I took a note to count the cars last time I rode over the bridge - the middle lanes were bumper-to-bumper, but only two vehicles used the outer streetcar lane. It’s open and accessible, the drivers just choose to avoid it. Even the current pedestrian/bike path in the former streetcar lane on the other side is too narrow to use, which is why adding more pedestrian space is necessary.

The 4 car lanes on the top level are the ones that repurposed the original pedestrian path, as well as replacing two additional railway tracks.

What about the “Protocol on Mines, Booby-Traps and Other Devices” that somebody linked above? Not sure if it’s the same as the “1996 Geneva Amendments” you mention, but both Ukraine and Russia are listed as signatories, and the language does seem to me to cover this exact situation:

Article 7
Prohibitions on the Use of booby-traps and other devices

1. Without prejudice to the rules of international applicable in armed conflict relating to treachery and perfidy, it is prohibited in all circumstances to use booby-traps and other devices which are any way attached to or associated with:
   (a) internationally recognized protective emblems, signs or signals;
   …
   (d) medical facilities, medical equipment, medical supplies or medical transportation;

It says “medical supplies”, without reference to humanitarian aid, and clearly stressing in “any way associated with”. A “red cross” is also a recognized emblem. I can appreciate how “humanitarian aid” can be narrowly defined as medical supplies under direct control and chain-of-custody of the Red Cross Organization and doesn’t apply to random medkits. But I can’t see how this language above would not apply.

Or is it the case that this would be a crime, committed during war, but not a war crime? How does that work? Does it have to be a violation of a specific Geneva Convention® version to count as a war crime, and not just any UN war-related convention?

Only because it’s English and the model is already trained on a large corpus of English text, so it has some idea of what a “table row” is for example. It could learn the concept from reading assembly code from scratch, it would just take longer. Hell, even Lego bricks can be trained on! https://avalovelace1.github.io/LegoGPT/

Our system tokenizes a LEGO design into a sequence of text tokens, ordered in a raster-scan manner from bottom to top. … At inference time, LegoGPT generates LEGO designs incrementally by predicting one brick at a time given a text prompt.
