- Comment on Shipping costs will no longer exist if teleportation is invented. 15 hours ago:
Again, the 1kg of carbon was only used to come up with the rough amount of atoms for 1kg of weight.
Last I checked, humans, same as most other things, don’t just consist of pure carbon. Also, you need to include position data as well, so even in our 1kg of carbon no two atoms are exactly the same since no two atoms are at the same exact position and same exact rotation. And no two atoms are bonded to the same exact atoms.
If you send just the data of “dump 1kg of carbon atoms there”, you will turn a diamond into carbon dust when teleporting it. I don’t want to see the result of what happens if you teleport a human that way.
And you actually don’t only have to take the atomic properties into consideration but also the subatomic ones. The 1 byte per atom was already purpousely a ridiculously low guess. It’s much more likely you need data in the order of megabytes per atom.
Sci fi makes teleportation look easy. Press a button, disappear here, reappear there.
In reality, every single component of teleportation is so hard that we don’t even have a clue how this could theoretically be done with future tech. We don’t have a way to scan anything (let alone a human being) with nearly the level of detail that we’d need. We don’t have a way to deconstruct the item that is supposed to be sent. We have neither a way to store nor to send the enormous amounts of data required. And we have no concept of a clue how to do the reconstruction.
Just to visualize this a bit better: it will be much, much easier to clone objects than to teleport them, because teleporting is cloning plus deconstruction.
So if you understand that creating objects out of thin air is resource-intensive, then that necessarily means that teleportation will be even more difficult and expensive than just cloning objects.
- Comment on Marketing Doesn't Work on Nerds 19 hours ago:
Those aren’t white papers. They are scientific papers.
White papers are written by companies as a marketing tool. The first two papers you linked above are written by universities and the last one by a research-focussed non-profit.
As per Wikipedia:
Since the 1990s, this type of document has proliferated in business. Today, a business-to-business (B2B) white paper falls under grey literature, more akin to a marketing presentation meant to persuade customers and partners, and promote a certain product or viewpoint.
- Comment on Marketing Doesn't Work on Nerds 1 day ago:
White papers are shit written by marketing people who try to make their little ad sound like something academic. In truth these white papers are in equal parts misunderstandings, wrong and full of useless fluff. They are AI slop, often completely without any AI involvement.
If someone is serious about the content, they call it a documentation, reference or datasheet.
- Comment on Shipping costs will no longer exist if teleportation is invented. 1 day ago:
This really depends.
Teleportation consists of three main phases:
- scanning/deconstruction
- sending
- reconstruction
If the deconstruction and/or reconstruction phases cost a ton of energy, it doesn’t matter if the sending phase has a high energy bill.
But since you have transmit data on each atom, you will have huge amounts of data to send.
For example, 1kg of carbon has about 5*10^25 atoms. Humans aren’t made entirely of carbon, but the rough order of magnitude will be similar. Let’s go with a 70kg human and we end up with roughly 10^27 atoms.
Let’s say we have good compression techniques and a single byte is enough to store all data of one atom. That means, we need to send about 10^28 bits of data.
In September 2023 the total bandwith of the global internet was about 1.2 Pbps, or 10^15 bits per second.
So to transmit a single human being with the speed of the entire global internet combined it would take 10^13 seconds or about 300 000 years. I think that kind of data transmission could cost a little bit of money.
Compare that to the cost of shipping 70kg of human being anywhere on the planet. By plane, it will cost in the order of a few thousand Euros and it will take one day, two at most, not 300 000 years.
- Comment on Looking to get my first 3d printer, any suggestions? 1 day ago:
You first have to determine what you want.
- Do you primarily want to print or do you want to tinker? An Ender 3 is not an out-of-the-box printer, especially not an used one where you have no idea what the last owner did to it. So if you want to tinker, that’s ok.
- Do you want great quality or a great price? An Ender 3 is quite outdated and compared to newer devices the quality isn’t great. If you are ok with that, it might be ok for you.
- Do you want a fast printer? An Ender 3 is slow by modern standards. It prints around 60mm/s stock and you might be able to get it to 100mm/s, maybe 120, but quality will suffer hard. Most modern printers do around 300mm/s stock and can be pushed to 600-700mm/s. This can reduce print times from 5h to maybe half an hour.
- Just to double check: are you ok with buying a potentially abused device with worn-down components that might cause hard to debug and costly to fix problems as your first printer?
If all that fits for you, then the Ender 3 will be good for you.
If it doesn’t, spend €200 and get a Bambulab A1 Mini.

That’s why in most other languages (and that works in english too), if you don’t want to specifically mark the end of your quote, you just say something like “And the he said, I quote, your mom is so fat that she has her own gravitational well.”
No need or point to put an unnecesary “end quote” marker before the beginning of your quote.

Yes, and how many helicopters fly regular passengers over your city?
There’s a reason these are speciality vehicles for speciality operations, and not a generic form of transport used all the time.

Tbh, I hate in much more when people say “quote unquote” before starting their quote.
It’s like writing ""Here is the quoted text.
Unquote ends the quote. So “quote unquote” means ""Here’s an empty quote, now let me ramble on about something that is not a quote.

- Comment on Why did in game cameras take so long to get good?🤔 2 days ago:
The single stick was a huge limitation. A really good example for that is Zelda Skyward Sword. By the time that game came out 3rd person 3D had been around for three console generations and more than a decade already, so there was more than enough time to figure out how to do this.
Yet the camera was still one of the biggest obstacles in the game. It happened so often to me that the camera got stuck in some stupid angle and I had to use their clunky manual camera aim option to see what I needed to see.
BotW’s dual-stick camera on the other hand had close to no issues at all. Having a full stick dedicated to just controlling the camera really solves the problem.
PC, which is in many ways the gold standard platform for 1st and 3rd person games, has a very similar solution with the 2-axis mouse control being reserved for camera control.
Automatic cameras are always worse than manual ones, because guessing what the player wants to look at just works worse than allowing the player to control it directly.
- Comment on Mods react as Reddit kicks some of them out again: “This will break the site” 2 days ago:
Tbh, I’m active in some modless subs, and apart from the occasional spam or lost redditor it mostly works. r/Arduino (iirc) for example is unmoderated and not exactly small.
People downvote garbage content and it gets hidden fast.
Compare that to e.g. r/showerthoughts which is so heavily moderated that you need a masters degree just to manage to post there without getting your content deleted or r/WiiUHacks where the mods ban you for mentioning the wrong Wii U hacking project (e.g. Pretendo).
The AI moderation is crap as well, but the upvote/downvote system is robust enough to work as a makeshift automoderation system.

- Comment on The entire teenage population is different every five years. 2 days ago:
There’s two terms: “Jugendlicher” and “Jugend-”. “Jugend-” can be used as a prefix for all sorts of things with all sorts of age limits (for example the SPÖ Jugendorganisation goes up to age 45 for some crazy reason). “Jugendlicher” on the other hand is really just used as a term for people until they reach the age of legal adulthood.
- Comment on The entire teenage population is different every five years. 2 days ago:
This is what makes experienced history so extremely short.
In general, people have a somewhat ok understanding of how their grandparents lived, and they might know a few stories about their great-grandparents, maybe one more generation after that, but that where it ends and where history books with dates and numbers begin.
That’s where you get statements like “In the past people did/believed/were like/… X” from. No, your grandparents did/believed/were like/… X, not all people in the past.
- Comment on The entire teenage population is different every five years. 2 days ago:
Most other languages count that group as “youths” and in general you are one from 12-18.
- Comment on If men had babies instead of women? Men would probably just all get C sections because everyone knows people have to keep being born. 2 days ago:
If men would be the ones getting pregnant, they would be women.
Almost all of the things that differentiale men and women in practice originated with who is doing the childbrithing and the resulting consequences.

This. Unless there’s some very special circumstances, a natural birth has much less risk of long term compications.
- Comment on Republicans put tech firms in a vise on Kirk social-media posts 3 days ago:
You are right that any crisis shakes up things and that even someone looking pretty good right now might get in trouble.
But on the one hand we are talking about people with wealth in the order of the GDP of a mid-sized country.
Meta truely is a one-trick-pony, with ads making up almost all of their income, and of course they could be in trouble if a scenario like what you suggested were to happen.
On the other hand, Zuck has money without end, so he can buy whatever would continue to make him money.
- Comment on Republicans put tech firms in a vise on Kirk social-media posts 3 days ago:
And I don’t think it will cost them tons of money. Yes, Trump does and will continue to do a ton of damage, no question about that. But the ultra-rich have money enough to weather the storm, and they have money enough to buy out every competitor who cannot weather the storm for discount prices.
Look at any major crisis in the last 50 years. Every single time without fail the rich benefit from the crisis and make it out with more money and more wealth inequality than before.

You might have misunderstood what the idiots who run these tech companies want.
Their goal is to make money, preferrably now more than tomorrow. So if licking some boots now will make them money, they will gladly do so.
Do you really think Zuckerberg has an actual stance on content moderation? He doesn’t like it because it costs money, but if it costs him more money to not do it, he will gladly do it.
There is no lession to be learned by those parasites.

- Comment on Vibe coding has turned senior devs into ‘AI babysitters,’ but they say it’s worth it | TechCrunch 4 days ago:
Yours is pretty much the best-case scenario for AI:
- Super small project, maybe a few dozen lines at most
- Greenfield: no dependencies, no old code, nothing to consider apart from the problem at hand
- Disposable: once the job is done you discard it and won’t need to maintain it
- Someone most likely already did the same thing or did something very similar and the LLM can draw on that, modify it slightly and serve it as innovation
- It’s a subject where you are good enough that you can verify what the LLM spits out, but where you’d have to spend hours and hours to read into how to do it
For that kind of stuff it’s totally OK to use an LLM. It’s like googleing, finding a ready-made solution on Stackexchange, running that once and discarding it, just in a more modern wrapping. I’ve done something similar too.
But for real work on real projects, LLM is more often than not a time waster and not a productivity gain.
- Comment on Vibe coding has turned senior devs into ‘AI babysitters,’ but they say it’s worth it | TechCrunch 4 days ago:
In real code, so after the first week of development, typing really isn’t what I spend most of my time on. Fancy autocomplete can sometimes be right and then it saves a few seconds, but not nearly 50-100% added productivity. Maybe more like 1-2%.
If I get a single unnecessary failed compile from the autocomplete code, it loses me more time than it saved.
But it does feel nice not having to type out stuff.
That’s why all research on this topic says that AI assistance feels like a 20-30% productivity boost (when the developers are asked to estimate how much time they saved) while the actual time spent on the task actually goes up by 20-30% (so productivity gets lost).

If you bring a 6yo into office and tell them to do your work for you, you should be locked up. For multiple reasons.
Not sure why they thought that was a positive comparison.
- Comment on Marriage is FOMO 5 days ago:
(a) depends on the country and (b) is always slower and more complicated than when married.
Say your partner gets hospitalized and isn’t concious. As a married person you have the same last name and done. As an unmarried person like you say, you first have to go hompe, find that notarized paper, convince the hospital lawyer that it means and likely you will have to repeat the process for each new hospital stay.
