“AI” Hurts Consumers and Workers -- and Isn’t Intelligent
  • I would argue that what's going on is that they are compressing information. And it just so happens that the most compact way to represent a generative system (like mathematical relations for instance) is to model their generative structure. For instance, it's much more efficient to represent addition by figuring out how to add two numbers, than by memorizing all possible combinations of numbers and their sum. So implicit in compression is the need to discover generalizations. But, the network has limited capacity and limited "looping power", and it doesn't really know what a number is, so it has to figure all this out by example and as a result will often come to approximate versions of these generalizations. Thus, it will often appear to be intelligent until it encounters something that doesn't quite fit whatever approximation it came up with and will suddenly get something wrong that seems outside the pattern that you thought it understood, because it's hard to predict what it's captured at a very deep level and what it only has surface concepts of.

    In other words, I think it is "kind of" thinking, if thinking can be considered a kind of computation, but it doesn't always capture concepts completely because it's not quite good enough at generalizing what it's learned, but it's just good enough to appear really smart within a certain distribution of inputs.

    Which, in a way, isn't so different from us, but is maybe not the same as how we learn and naturally integrate information.

    It was through a video call – where only the photograph of a man who was the same as Minister Jackson, with a cap and glasses – was seen where the imposter began to give orders to the two workers, who work at night. First, they removed 50 laptops from the different floors of the ministry. https://newsrnd.com/news/2023-07-22--negro-chico---the-prisoner-who-posed-as-a-chilean-minister-and-put-the-boric-government-on-the-ropes.r1-S2_TOcn.html

  • anytype — decentralized, p2p, e2ee 'Notion' like app
  • We use Notion at work and one thing that worries me is how the hell I'd make a local backup of all the data we're putting on there. If there were a way to import my Notion data into something like this it would make a fantastic solution.

  • How are you accessing Lemmy now? Browser or app?
  • I was using Jerboa because i was used to Sync for reddit. But, I got a bit tired of how rough around the edges it is, so I switched to just installing my Lemmy instance front page as Firefox "app" on my phone and realized it's not that bad as a UI, so sticking with it for now.

    I'll probably try apps again in the future but I feel more open to "installing" good web apps now. Incidentally I tried the same trick with Reddit's mobile interface after Sync stopped working and realized it's also not so awful as I remembered. I did prefer Sync but I'll see how it goes with this method. So it's mobile web interfaces on Android for me for now.

    Having said that, in both cases I think I'd prefer a more "simple HTML" type experience like old reddit over these dynamic SPA things they both have going.

  • Literally had a meeting with someone yesterday who, after starting late because of trouble logging in and things crashing, started off the meeting by apologizing for using Teams but said it was just easier because it's the default. Made me chuckle.

    Anyone who chooses Teams because they actually think it's better.. I just.. are we even using the same program?

  • likely violate that data’s usage agreement.

    It doesn't seem to be too common for books to include specific clauses or EULAs that prohibit their use as data in machine learning systems. I'm curious if there are really any aspects that cover this without it being explicitly mentioned. I guess we'll find out.

  • New C++ features in GCC 13
  • really curious about contracts. It seems from the example that they are a runtime thing so what is the advantage over just putting some checks in your code at the top and bottom of the function? Does it allow the compiler to help infer compile time conditions at all?

  • How to nest context managers while hiding the dependency?
  • Huh, so a sort of factory pattern to encapsulate construction. I feel it's slightly awkward as construction has to happen outside the object, but maybe usable. At least nicer than calling __enter__() explicitly. Thanks, definitely an option I'll consider.

    How to nest context managers while hiding the dependency?

    Let's say I have a context manager that provides a resource that then mutates on exit:

    ``` from contextlib import contextmanager

    @contextmanager def context(): x = ['hi'] yield x x[0] = 'there' ```

    I found that if I want to make another context class that uses this, such that the context (before mutation) is valid, I have to pass it in:

    ``` class Example1: def init(self, obj): self.obj = obj def use_obj(self): print(self.obj) def enter(self): print("start") return self def exit(self, *exc): print("end")

    with context() as x: with Example1(x) as y: y.use_obj() ```

    prints:

    start ['hi'] end

    However, what I don't like is, let's say that obj is an internal detail of my class. I don't want the user to have to define it beforehand and pass it in.

    The only way I can figure how to do this is by calling the context manager's __enter__() explicitly:

    ``` class Example2: def use_obj(self): print(self.obj) def enter(self): print("start") self.ctx = context() self.obj = self.ctx.enter() return self def exit(self, *exc): print("end") self.ctx.exit(None, None, None)

    with Example2() as y: y.use_obj() ```

    which also prints,

    start ['hi'] end

    For comparison, just as some other random attempt, the following doesn't work because the context ends when self.obj is created:

    ``` class Example3: def use_obj(self): print(self.obj) def enter(self): print("start") with context() as x: self.obj = x return self def exit(self, *exc): print("end")

    with Example3() as y: y.use_obj() ```

    which prints,

    start ['there'] end

    Okay, so my point is that Example2 is the right solution here. But, it's really ugly. So my question is, is there a better way to write Example2?

    Super-communities?

    An idea that just occurred to me. I was looking for communities on machine learning to join, so I searched https://browse.feddit.de/ and found a bunch. They don't have much content but together they have at least 4 or 5 posts each, which adds up to a few posts, so I subscribed to all of them.

    However, now I have no way of "grouping" them so that I can view posts of all communities in my feed related to the topic of machine learning.

    I was wondering if some concept of "super communities" could be interesting for Lemmy, similar to "multireddits". People could curate their collection of favourite communities around a topic, over multiple instances, and users could easily subscribe and browse the whole bunch of them.

    feature request: when clicking on a link to a community, open it in Jerboa
  • And this is an even bigger problem on communities on other instances, since you are not only signed out, you don't even have an account there. So you are forced to go back to your instance and search for it, hoping that it is seen through federation. imho what should happen in that case is that Jerboa should "adapt" the URL so that you see the community as from your own account's instance. So if I click on a link to blah.ml/c/blahcommunity, that should actually open lemmy.ml/c/[email protected]. Hm, but actually it shouldn't do that because it should just open the community directly in Jerboa. But that would be second best.

  • Are we using Lemmy correctly?
  • This is a good point and makes me wonder: is there any interest in running a personal instance that has no communities, just for the sake of being in control of your own identity? Would that even be an appropriate thing to do? And if so, how would you convince instances to federate with you if you have no content?
