  • Every year or two I give Windows a genuine try for around a month. WSL2 is actually pretty decent, it’s a massive improvement on the Windows development experience I had back in 2015 when I tried running Windows full time doing Python/Ruby/Java development. Required cygwin, git bash, power shell, and cmd depending on what I was doing. It was a special kind of nightmare. Lots of native gems couldn’t compile, lots of tooling issues, etc.

    Now you can use exclusively Windows terminal, keep essentially all your development stuff in a Linux subsystem, and pretend you’re in Linux. Integration with things like vscode or intellij is quite decent with the WSL.

    That said, I hate Microsoft, hate the lack of customization, hate the default UI, hate the split between Windows 95-style settings and new Windows 10+, it’s inconsistent as hell. Moving windows across monitors with different scaling still resizes the windows in a very archaic way. You can’t reasonably use multiple desktops because you can’t easily rebind keys to swap desktops without third party software. I’ve changed DEs in Linux for smaller issues than these.


  • Yeah for both Ubuntu and Arch on two separate computers in my house, the process was just install the distro then install steam + Lutris (steam for steam games, Lutris for every other kind of game like League or WoW).

    Installing steam games is identical in Linux and Windows for the vast majority of games. Installing non-steam games is arguably easier since you never have to go to a web browser.

    Honestly the only reason Windows is “easier” is because it’s preinstalled on computers. As someone who has fresh installed Linux and Windows, Linux is miles easier to install. To install Windows 11 I tried following their recommendations (enabling TPM and secure boot in bios), but the W11 installer still didn’t like my 2 year old computer, so had to open up the command prompt, regedit, and add 3 Bypass registry DWord 32 bit values. Then actually installing the O.S you just sit there and wait with an unusable computer. Linux installations have nice GUIs that are far more modern, don’t require weird terminal hacks, and you have a usable computer while it’s installing (you can open up Firefox and browse the web for example).

    Note: Lemmy code blocks don’t play nice with some symbols, specifically < and & in the following code examples

    This isn’t a language level issue really though, Haskell can be equally ergonomic.

    The weird thing about ?. is that it’s actually overloaded, it can mean:

    • call a function on A? that returns B?
    • call a function on A? that returns B

    you’d end up with B? in either case

    Say you have these functions

    toInt :: String -> Maybe Int
    
    double :: Int -> Int
    
    isValid :: Int -> Maybe Int
    

    and you want to construct the following using these 3 functions

    fn :: Maybe String -> Maybe Int
    

    in a Rust-type syntax, you’d call

    str?.toInt()?.double()?.isValid()
    

    in Haskell you’d have two different operators here

    str >>= toInt &lt;&amp;> double >>= isValid
    

    however you can define this type class

    class Chainable f a b fb where
        (?.) :: f a -> (a -> fb) -> f b
    
    instance Functor f => Chainable f a b b where
        (?.) = (&lt;&amp;>)
    
    instance Monad m => Chainable m a b (m b) where
        (?.) = (>>=)
    

    and then get roughly the same syntax as rust without introducing a new language feature

    str ?. toInt ?. double ?. isValid
    

    though this is more general than just Maybes (it works with any functor/monad), and maybe you wouldn’t want it to be. In that case you’d do this

    class Chainable a b fb where
        (?.) :: Maybe a -> (a -> fb) -> Maybe b
    
    instance Chainable a b b where
        (?.) = (&lt;&amp;>)
    
    instance Chainable a b (Maybe b) where
        (?.) = (>>=)
    

    restricting it to only maybes could also theoretically help type inference.

    Here’s an example (first in Haskell then in Go), lets say you have some types/functions:

    • type Possible a = Either String a
    • data User = User { name :: String, age :: Int }
    • validateName :: String -> Possible String
    • validateAge :: Int -> Possible Int

    then you can make

    mkValidUser :: String -> Int -> Possible User
    mkValidUser name age = do
      validatedName ← validateName name
      validatedAge  ← validateAge age
      pure $ User validatedName validatedAge
    

    for some reason <- in lemmy shows up as &lt;- inside code blocks, so I used the left arrow unicode in the above instead

    in Go you’d have these

    • (no Possible type alias, Go can’t do generic type aliases yet, there’s an open issue for it)
    • type User struct { Name string; Age int }
    • func validateName(name string) (string, error)
    • func validateAge(age int) (int, error)

    and with them you’d make:

    func mkValidUser(name string, age int) (*User, error) {
      validatedName, err = validateName(name)
      if err != nil {
        return nil, err
      }
    
      validatedAge, err = validateAge(age)
      if err != nil {
        return nil, err
      }
    
      return User(Name: validatedName, Age: validatedAge), nil
    }
    

    In the Haskell, the fact that Either is a monad is saving you from a lot of boilerplate. You don’t have to explicitly handle the Left/error case, if any of the Eithers end up being a Left value then it’ll correctly “short-circuit” and the function will evaluate to that Left value.

    Without using the fact that it’s a functor/monad (e.g you have no access to fmap/>>=/do syntax), you’d end up with code that has a similar amount of boilerplate to the Go code (notice we have to handle each Left case now):

    mkValidUser :: String -> Int -> Possible User
    mkValidUser name age =
      case (validatedName name, validateAge age) of
        (Left nameErr, _) => Left nameErr
        (_, Left ageErr)  => Left ageErr
        (Right validatedName, Right validatedAge) => 
          Right $ User validatedName validatedAge
    

  • For people unfamiliar with the vim ecosystem (I assume that’s at least part of the down votes), it’s actually much closer than you’d expect. If you’re only familiar with vi/vim, nvim customizations are essentially on feature parity with vscode, with the added benefit of the vim-first bindings.

    What you have to do is install a customized neovim environment. Lunarvim, astrovim, nvchad, etc. Most of them have single line installation options for Linux, and then it comes with a bunch of plugins that will pretty much match whatever you’d find with vscode extensions.


  • Agree on majority of the post, except for “make the choices you feel are right”. Hard disagree on this normatively. If you’re saying it descriptively, sure, but it’s essentially tautological at that point.

    We shouldn’t advocate that people just act in whatever way feels correct to them. Sociopaths feel like it’s okay to do things that are not okay. So do bigots, racists, speciesists, sexists, etc.

    We should instead do what you’re doing with the majority of your post, advocate for correct positions and then come to a rational conclusion with the people we are talking to. Giving them a get out of jail free card, permitting them to do literally anything, is unnecessary.

    You identified yourself as an advocate for (regulated) capitalism

    Central characteristics of capitalism include capital accumulation, competitive markets, price systems, private property, property rights recognition, voluntary exchange, and wage labor. In a market economy, decision-making and investments are determined by owners of wealth, property, or ability to maneuver capital or production ability in capital and financial markets—whereas prices and the distribution of goods and services are mainly determined by competition in goods and services markets.

    Yes there is more to this, welfare capitalism exists where in exceptional circumstances (e.g food, sometimes basic shelter, etc.) goods are distributed outside of the market system, but it’s totally fair to infer that a capitalist would advocate that the market is setting the levels of compensation for the vast majority of professions.

    Arguing that these levels of compensation should be agreed upon democratically is an entirely socialist position. This is an advocacy for central, democratic planning that flies in direct opposition to capitalism.

    It seems like you’re probably a capitalist-realistic (you believe no other economic system is viable), but you recognize the faults of capitalism and are trying to reform essentially every aspect of the economy to be socialist while still keeping some extremely small sliver of bourgeoise so you can call yourself a capitalist and feel like your position is a “realistic” one.

    The irony is that keeping this however small and crippled parasitic class of capitalists around is always an existential threat to the working class. They’re a group of people whose economic interests are in opposition to our own. We don’t need people with different relationships to capital just by a happenstance of birth or luck.

    There’s a phenomenon in psychology called “crowding out”, where extrinsic motivators (e.g money) can destroy intrinsic motivators (e.g passion), because they’re more important (you need money to survive, you don’t need passion).

    The take that communism is bad for incentives and capitalism is good for incentives is far too naive. What capitalism can do effectively is make a large mass of people do a lot of work they don’t want to do, and turn work they do want to do into a nightmare, where communism would instead focus on reducing the overall burden of unpleasant work, and find non-market solutions for distributing the unpleasant work.

    Automating the bad away then becomes a positive instead of an existential threat to our existence. Many other contradictions of capitalism fall away when we look towards non-capitalists modes of production.

    A lot of people frame non-market solutions as “compulsory”, and market solutions as “free”, even though again that’s far too reductive, having the choice between starving and janitorial work isn’t really a good faith choice, and yet these are the kinds of choices capitalism uses and calls the epitome of freedom.








  • You can’t tell someone they’re being pseudo-scientific and then accuse them of being adversarial as if you’re not.

    I wasn’t using circular reasoning, I was citing data. 90,000 rent controlled housing units in NYC are left vacant (this number has been rising). As we both understand, “individual” (either actually an individual or a corporation) capitalists act in their own best interests. They’re not leaving these apartments vacant for years just because they want to fuck over poor people, they’re doing it because they make more money off their other supply if these units are kept off the market.

    If you don’t want to feel like you’re spouting alt-right talking points, stop using verbatim the talking points that capitalists use to defend housing scalpers. At best, your entire point is “housing scalpers aren’t as big of a deal as this other problem”, and at worst you’re ignoring the real problem so capitalists can keep exploiting the housing market.

    You haven’t made a case in favor of housing scalpers, and for good reason, there’s literally no case to be made for them. The capitalist position is that scalping houses isn’t a big enough problem to have an effect on supply. Even if that were true (which would require 16 million housing units being vacant having no impact on housing supply), it doesn’t mean that it couldnt be true in the future. What if the number rose to 30 million vacant units with the same population? Or 100 million? Or a billion? At some point it gets ridiculous. To me that’s pretty clearly when you’re at “we have 30x as many vacant houses as homeless people”, but maybe your tolerance is much higher because homeless people aren’t economically valuable to capitalists (except as a reserve army of labor).
