  • In addition to what groet said, I’ll add that this is a little bit like asking “what’s the difference between a public library and Amazon?”.

    Yes, there are other public libraries you could go to if the one you subscribe to didn’t have something you wanted or ‘went bad’ somehow, but the most important difference is you don’t have an antagonistic relationship with your public library. Your public library doesn’t have a financial incentive to try to trap you or screw you over.


  • An antivirus is mostly just a blacklist of known malware. Sometimes heuristics are used such as ‘this piece of software isn’t installed on many PCs, and it appears to be doing shady stuff like, monitoring keystrokes or listening to your microphone’. But unless your antivirus is actually sentient there’s no way for it to really distinguish between a chat application that listens to your microphone so you can talk to your friends / monitor your keystrokes to know when you’ve hit the push-to-talk key, and a piece of actual malware that intends to spy on you and blackmail you.

    What you have with a package manager is a whitelist of programs that have been selected by your distro maintainers. Is it completely impossible for someone to sneak malware into a distro’s repository? No, but its a lot easier to maintain a list of known good software than it is to maintain a list of known bad software. And in that situation your antivirus isn’t going to help you anyway, since the people maintaining its malware list aren’t going to magically know that something is malware before the distro maintainers do.

    So, generally, just using your package manager instead of running random shit you find online is going to be a lot better than any antivirus. With things like Wayland and Flatseal becoming more common we’re heading towards a situation where fine-grained per-package permissions will become the standard way distros do things, making antivirus even more unnecessary.

    We should have done that a long time ago, as the security model of ‘any program you run can do anything you can by default’, then blacklist the ones that inevitability abuse that privilege, is completely backwards.



  • Are you misreading “preparing” as literally any writing

    “Prepare derivative works” means not just any writing, but literally anything creative. If you paint a picture of a character from a book, using specific details described in that book such as their appearance and name, you are creating a derivative work.

    https://law.stackexchange.com/questions/78442/what-is-considered-a-derivative-work

    Even that Wikipedia article goes into fair use.

    Fair use carves out an exception for parody, criticism, discussion, and education. “Entertainment” or “because I like the series and these characters” are not one of those reasons. Fan fiction might qualify as parody though.

    What effect on the market can there be for a fan remaster of a 20 year old game that isn’t for sale anymore? Hard to argue that doesn’t fall under fair use.

    This is not how “the effect of the use upon the potential market for or the value of the copyrighted work” part of fair use works.

    A company can create a work, sit on it for literally 100 years doing nothing with it and making not a single cent from it, then sue you for making a nonprofit fan work of it. Steamboat Willie is 95 years old and until just this year you could have been sued for drawing him. Note that, in the eyes of the law, Steamboat Willie is effectively a different character than Mickey Mouse.

    Again, I cannot stress enough how it doesn’t matter at all whether you are personally profiting from something or whether you are affecting a market. The word “potential” in that quote above is doing a lot of work:

    A father in the UK wanted to put spiderman on the grave stone of his 4 year old son who loved the character. Disney said “no”. Disney does not make tombstones. You are not eating into their profits by putting spiderman on a tombstone. And yet in the eyes of the law Disney has every right to stop you since they might decide to start up a tombstone business next week.

    Nothing I have written here is legal advice.

    EDIT: I am not a fan of any of this. I think you should be able to write nonprofit fanfiction without worrying that some corporation might sue you. I am on your side on this. But this is the reality we live in.











  • This model isn’t “learning” anything in any way that is even remotely like how humans learn. You are deliberately simplifying the complexity of the human brain to make that comparison.

    I do think the complexity of artificial neural networks is overstated. A real neuron is a lot more complex than an artificial one, and real neurons are not simply feed forward like ANNs (which have to be because they are trained using back-propagation), but instead have their own spontaneous activity (which kinda implies that real neural networks don’t learn using stochastic gradient descent with back-propagation). But to say that there’s nothing at all comparable between the way humans learn and the way ANNs learn is wrong IMO.

    If you read books such as V.S. Ramachandran and Sandra Blakeslee’s Phantoms in the Brain or Oliver Sacks’ The Man Who Mistook His Wife For a Hat you will see lots of descriptions of patients with anosognosia brought on by brain injury. These are people who, for example, are unable to see but also incapable of recognizing this inability. If you ask them to describe what they see in front of them they will make something up on the spot (in a process called confabulation) and not realize they’ve done it. They’ll tell you what they’ve made up while believing that they’re telling the truth. (Vision is just one example, anosognosia can manifest in many different cognitive domains).

    It is V.S Ramachandran’s belief that there are two processes that occur in the Brain, a confabulator (or “yes man” so to speak) and an anomaly detector (or “critic”). The yes-man’s job is to offer up explanations for sensory input that fit within the existing mental model of the world, whereas the critic’s job is to advocate for changing the world-model to fit the sensory input. In patients with anosognosia something has gone wrong in the connection between the critic and the yes man in a particular cognitive domain, and as a result the yes-man is the only one doing any work. Even in a healthy brain you can see the effects of the interplay between these two processes, such as with the placebo effect and in hallucinations brought on by sensory deprivation.

    I think ANNs in general and LLMs in particular are similar to the yes-man process, but lack a critic to go along with it.

    What implications does that have on copyright law? I don’t know. Real neurons in a petri dish have already been trained to play games like DOOM and control the yoke of a simulated airplane. If they were trained instead to somehow draw pictures what would the legal implications of that be?

    There’s a belief that laws and political systems are derived from some sort of deep philosophical insight, but I think most of the time they’re really just whatever works in practice. So, what I’m trying to say is that we can just agree that what OpenAI does is bad and should be illegal without having to come up with a moral imperative that forces us to ban it.






  • CRI is defined as how closely a light source matches the spectral emission of a thing glowing at a specific temperature. So, for a light source with a 4000 k color temperature its CRI describes how closely its emission matches that of an object that’s been heated to 4000 k.

    Because incandescent bulbs emit light by heating a filament by definition they will have 100 CRI and its impossible to get any better than that. But the emission curve of incandescent lights doesn’t actually resemble that of sunlight at all (sorry for the reddit link). The sun is much hotter than any incandescent bulb and it’s light is filtered by our atmosphere, resulting in a much flatter more gently sloping emission curve vs the incandescent curve which is extremely lopsided towards the red.

    As you can see in the above link, there are certain high end LED bulbs that do a much better job replicating noon day sunlight than incandescents. And that flatter emissions profile probably provides better color rendering (in terms of being able to distinguish one color from another) than the incandescent ramp.

    Now, whether or not you want your bulbs to look like the noon day sun is another matter. Maybe you don’t want to disrupt your sleep schedule and you’d much rather their emissions resemble the sunset or a campfire (though in that case many halogen and high output incandescent lamps don’t do a great job either). Or maybe you’re trying to treat seasonal depression and extra sunlight is exactly what you want. But in any case I think CRI isn’t a very useful unit (another reddit link).
