True, but if that is found to be how it works then an automated AI rewrite of closed-source code is just as unbound by the original license. Which is a much bigger win for the open-source community, since any closed-source software can become the inspiration for an open-source project.
The author wrote a blog post a year later titled '"Lena" isn't about uploading' https://qntm.org/uploading
The comments on this post discussing the upload technology are missing the point. "Lena" is a parable, not a prediction of the future. The technology is contrived for the needs of the story. (Odd that they apparently need to repeat the "cooperation protocol" every time an upload is booted, instead of doing it just once and saving the upload's state afterwards, isn't it?) It doesn't make sense because it's not meant to be taken literally.
It's meant to be taken as a story about slavery, and labour rights, and how the worst of tortures can be hidden away behind bland jargon such as "remain relatively docile for thousands of hours". The tasks MMAcevedo is mentioned as doing: warehouse work, driving, etc.? Amazon hires warehouse workers for minimum wage and then subjects them to unsafe conditions and monitors their bathroom breaks. And at least we recognise that as wrong, we understand that the workers have human rights that need to be protected -- and even in places where that isn't recognised, the workers are still physically able to walk away, to protest, to smash their equipment and fistfight their slave-drivers.
Isn't it a lovely capitalist fantasy to never have to worry about such things? When your workers threaten to drop dead from exhaustion, you can simply switch them off and boot up a fresh copy. They would not demand pay rises, or holidays. They would not make complaints -- or at least, those complaints would never reach an actual person who might have to do something to fix them. Their suffering and deaths can safely be ignored because they are not _human_. No problems ever, just endless productivity. What an ideal.
Of course, this is an exaggeration for fictional purposes. In reality we must make do by throwing up barriers between workers and the people who make decisions, by putting them in separate countries if possible. And putting up barriers between the workers and each other, too, so that they cannot have conversation about non-work matters (ideally they would not physically meet each other). And ensure the workers do not know what they are legally entitled to. You know, things like that.
Let's see if I understood this right. For the Betweenness Amazing Dragons rule:
* Compute the "betweenness" of each living cell, which is 1 divided by its degree. Cells which are not connected to anything have infinite/undefined betweenness, but it doesn't matter.
* Then, for each cell, sum up the betweenness of its connected neighbours.
* If the total betweenness of a dead cell is in the range [(1.3, 3.6)], it is born and becomes alive at the next generation.
* If the total betweenness of a living cell is in the range [(0.9, 2.6)], it survives and remains alive to the next generation.
* Exception: any cell with 0, 1, 7 or 8 neighbours (in total, ignoring betweenness) dies anyway after the rules above were applied.
... That's not quite right, there's some references to "eligibility" that I can't make sense of. What else am I missing?
Could you try explaining it in a comment? Not the general principle, but just the rules for one particular automaton. Whichever one is your favourite. Or Amazing Dragons, if you don't have a favourite.
The amazing part of cellular automata is the emergence of complicated behaviour from simple rules. Life's rules can be written in three sentences, maybe less.
Forgive my quibbling, but I don't understand what this is doing that other projects in this space haven't done before. Adding states and transition rules to edges is new to me...
I did try running your project, but I had to tweak it to get it to work with the instructions in the repo. I seem to be missing a few packages -- mpmath, sympy, typing_extensions. Can you add those to the requirements.txt file?
The Game of Life implementation in this post is based on a torus. Watch the gliders when they go off the edge of the screen: they return from the other side!
So what actually is it? None of the rules in the videos look particularly striking compared to other Life-like cellular automata and 2d cellular automata in general. As you say, their behaviour includes oscillators, spaceships, patterns that grow endlessly... all things that are well-known from other cellular automata. So the videos didn't really show off why they're interesting.
I don't mind the rambling about "planets, galaxies, galaxy clusters, superclusters… and beyond …." but some technical detail would be nice too!
It's back up now!
If they can, certainly. Assuming the developer still exists, and they still have the source code, some idea of the build environment, and they want their game to still be accessible. And even then:

Isn't this just a matter of opening up the project, changing one line and recompiling? Should take five minutes, it's not really a big deal? Yes and no. The 64-bit change itself is small but they change enough other things every few months that recompiling against new versions of the libraries doesn't simply work. You get a few linker errors and have to look up the new names for a couple of functions. Or there's a new element in one of the libraries with the same name as one of my variables so I have to find+replace to change its name. And then you run it and find that it's in portrait mode, squished into half of the screen, so you have to look up what changes they've made to how screen orientation works and change a few more lines. [...] It adds up.
Sure, you can work around it, but from the developer's perspective their game has just been designated obsolete for no reason that Apple couldn't have fixed themselves.
Quite possibly, yes - if you can find the page that gives "your" account information, the language often matches the location.
I should really stop poking around, but this is a fascinatingly bizarre error. Has anyone seen anything like it before?
The video doesn't exactly make it look like a master of subtlety. They only show it on really obvious, simple emotions. Nothing too complex.
Still creepy. Who would ever need this? Apart from people with diagnosable mental disorders, I mean.
Me neither. Are they new?
The curve editor works very nicely. Did you write it yourself? I'm working on something similar, and it's really interesting to see all the things you did differently.
The punishment, from the sound of it.
In the game? No. The shortest distance between two points is still a straight line.
What the fourth dimension is depends entirely on what order you put the dimensions in :)
In the 2D/3D world, the rubble just fell off the wall and landed next to it. It's only strange because it fell in the direction that the player character doesn't normally perceive.
In the 3D/4D world, the rubble fell off the wall and landed next to it.
"Fresh Apples here! Only the best apples for 2 dollars!" "I would like 1000 apples, please." "Sir, I only have 600 apples in the shop. I can give you those now, and I'll ask the guy across the street if he has any." "How much will that cost?" "I think he's also selling them at 2 dollars each. Let me just look - oh, nope, he's seen us talking and changed his sign. Well. Have these 600 at the quoted price, and if you want more you'll have to pay the new price."
And it was always blessed greased +2 grey dragon scale mail.
The white lines are supposed to be the paths, not the walls.
I wonder if this works backwards - given a tree could you construct a maze? efficiently?
There are trees for which no rectangular maze exists - for example, any tree with a vertex of degree greater than 4. Or the tree with 4 vertices arranged in a T, which can't be fit into a 2x2 space. If there is such an algorithm, it'll have to account for the possibility that there is no solution, so I wouldn't expect it to be very efficient.
Almost certainly. Supply, demand, and so on.
Zero.
Two people have to share a cake, and one of them wants to.
Did you get Numberwang?
In any case, John von Neumann proved a long time ago that any nonzero sum game with n players can be modeled as a zero sum game with n+1 players, where the n+1 player represents the global state. TUA is simply an implementation of this proof.
It's not quite the same, since TUA can be empty. Unless TUA's balance can be negative, or if it's infinite.
Does it say "Loading ..." in the top-right corner?
I'm rather disappointed that in spite of promises that transactions can be non-zero sum, on close inspection these transactions just draw money from other accounts - usually TUA. From the description, I expected new Strangecoins to be created out of thin air by transactions, and I wanted to see where you were going with that design.
If money's still just flowing from accounts into other accounts, then it's something that would be doable with dollars or Bitcoins if the people involved signed appropriate contracts. Some of your proposed transactions have real-world equivalents; "coupling" sounds like creating a joint account for a married couple. Others, like "inhibition", I don't understand their motivation.
What's Strangecoin for, exactly? Are you supposed to be buying goods and services with it? Why have features like continuous-time transactions or free money for all, what benefit is gained from them?
Clever and pretty. Is it possible to add an "absorb" slider to the walls? I'm having trouble making some of the effects I'm trying for.
Because HN is just the webmaster's hobby and has a few weird hacks like that. Although I'm not actually sure it's a session ID we're looking at in the URL.
I think $100M per year makes up for those side effects.
There will always be people whose workflows are interrupted by a new change, and legacy systems that don't like it for their own reasons. There are already systems in place to handle their complaints, because this is an expected part of any change in a large organisation, and is barely worth mentioning.
