  • He also points out that there are many ISBNs that are “wrong”, but are actually correct in the real world. This is because publishers don’t always understand about the checksum and just increment the ISBN when publishing a new book. In many library systems there is this checkbox next to the ISBN entry field where you can say something like “I understand this ISBN is wrong, but it is correct in the real world”.

    So just flagging wrong ISBNs would lead to a lot of false positives and would need specific structures to deal with that.

    Plants actually use O2 themselves a lot of the time, so we would still need to truck in a whole bunch of that stuff in. Also the amount of plants needed for just a single human is huge. Most plants are rather bad at producing O2. Most of it actually comes from algae living in water, not potted plants. The YouTube channel Joel Creates did an experiment with how much algae you would actually need to breathe. It’s like a lot, a lot a lot really. Building some place on Mars or even in orbit that such a large amount of algae could happily live is pretty hard. Hell it’s pretty hard on Earth, where you don’t need to worry about temperature and pressure going out of spec or stuff like radiation. These days we do have pretty effective LED grow lights that prevent the whole thing from becoming too hot. From movies people think space is cold, but getting rid of heat is a big problem. With that much light blasting into the water, the temperature rises and the algae will die from that at some point. So radiating away all that heat is a must. On Mars or the Moon this is easier as the surrounding rocks could be used as a heat sink. The actual real hard part is not just building this, but building it in a way that can support human life for a long time. Systems such as these are chaotic in nature and often suffer from cascade failure modes. If a little thing goes wrong and some of the algae dies, it often cascades into a full failure where all of it dies off. So there would need to be many smaller systems, isolated as much as possible to prevent cascading failures. The system would also need to be modular enough so it would be easy to disconnect a module, completely clean and sterilize it and put it back into use. With staggered phases applied as to not have large swings in output. As these systems would be rather large in scale and have many different complex parts, a high level of automation is required. And we haven’t even touched on getting all of this constructed somewhere and have it bootstrapped with enough water, with the right stuff in it and none of the wrong stuff. Enough reliable energy and nutrients to feed it all and transport living algae there to kick it all off. As far as I know nobody has ever gotten close to anything like this on Earth, let alone in space or on a place like the Moon or Mars. It would be a project that rivals the original Moon landings.

    It might sound like a simple enough concept and it is how we are currently living on this planet, so it should be possible. However keep in mind our planet has had huge swings in temperatures and atmospheric composition. There were many many times in Earth’s past where humans could not survive the conditions and we evolved here.





  • AI mostly learned it from programming tutorials and things like documentation and Q&A forums like StackOverflow. People often add comments in those cases to explain to somebody not familiar with code what is happening so they can learn from it.

    In actual code written by people who write code for a living I’d hope the comments are much more useful and usually not as prevalent.




  • I think you’d be surprised how fast entire groups of people surrender once you vaporize a couple of compounds where those militia hold up. You don’t need to kill each and every one of them, you just need to show how futile their fight is and they’ll give up quickly. This won’t be like some last stand situation where two parties stand off against each other. It’s a group of people concentrated in a small area against people who have weapons designed to kill a group of people concentrated in a small area. Sure, some small groups might turn to guerrilla tactics and blow shit up. But I think the people in charge are mostly fine with that. They don’t give two shits about the general public and have plenty of private and actual armies to protect themselves. It won’t change a thing and they’ll hunt down the worst offenders pretty quickly.


  • Good luck using those guns when you get painted by a Predator drone from 8 miles away and have a missile shoved down your throat at Mach 2. That won’t happen? Tell that to all those people on the boats the US blew up. Oh wait you can’t, they all got murdered.

    The idea of fat idiots with guns somehow being the heroes who defend democracy against the big bad government is a joke. Not only is the power difference fucking huge, most of those gun freaks are fascist and bootlickers themselves. They voted for that big bad government. Americans are among the most brainwashed in the world and they don’t even know it.
