  • 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.










  • No people don’t “just have the option to move away”, that’s an incredibly naive way to look at the world, some people need to be in certain locations for social or work reasons.

    Also, what I’m saying isn’t a “theory”, it’s an observation of data. You keep trying to rationalize it away, but whatever way you slice it you can’t get rid of the 16 million vacant houses that are not in use, while we have half a million homeless people and rising costs housing costs.

    You seem to be insinuating that people don’t just buy up housing and sit on it, like that’s not a phenomenon that exists because you can’t fathom why, despite my last comment clearly outlining several reasons how it could happen, and more importantly the fact that it does actually happen.

    1. Monopolies in certain areas. Your response? “They can move”
    2. Holding onto vacant rent controlled apartments to force people into more expensive units. Your response? “It wastes money” (untrue, in this situation it makes more money, which is why it happens in the real world).
    3. There are 16 million vacant housing units while we have half a million homeless people. Your response? Nothing, I guess those people’s interests aren’t as important as preserving the right for housing scalpers to hoard unused property.


  • There are a ton of reasons why individuals/corporations would scalp housing units and hold onto them without opening them up to use, from laws requiring fair treatment of renters like in NYC (where 90,000 rent controlled apartments remain vacant), to “unified cartels” actually have incredibly large influence over some areas (there are some companies that hold 10s of thousands of housing units, like blackrock, and these corporations purposefully keep some vacant to inflate the price of all units and control supply).

    But even if you want to just close your eyes and ignore my last paragraph, you can try to rationalize away the data, but the data will still be there. There are 16 million vacant housing units in the U.S. Even if you can’t fathom any reason why these might exist, they still do, and they still impact supply even if you’d like to believe they don’t.
