+title: Crimes with Go Generics

+---
+
+Go 1.18 added [generics](https://go.dev/doc/tutorial/generics) to the
+language. This allows you to have your types take types as parameters
+so that you can create composite types (types out of types). This lets
+you get a lot of expressivity and clarity about how you use Go.
+
+However, if you are looking for good ideas on how to use Go generics,
+this is not the post for you. This is full of bad ideas. This post is
+full of ways that you should not use Go generics in production. Do not
+copy the examples in this post into production. By reading this post
+you agree to not copy the examples in this post into production.
+
+I have put my code for this article [on my git
+server](https://tulpa.dev/internal/gonads). This repo has been
+intentionally designed to be difficult to use in production by me
+taking the following steps:
+
+1. I have created it under a Gitea organization named `internal`. This
+   will make it impossible for you to import the package unless you
+   are using it from a repo on my Gitea server. Signups are disabled
+   on that Gitea server. See
+   [here](https://go.dev/doc/go1.4#internalpackages) for more
+   information about the internal package rule.
+1. The package documentation contains a magic comment that will make
+   Staticcheck and other linters complain that you are using this
+   package even though it is deprecated.

+
+## `Queue[T]`
+
+To start things out, let's show off a problem in computer science that
+is normally difficult. Let's make a MPMS (multiple producer, multiple
+subscriber) queue.
+
+First we are going to need a struct to wrap everything around. It will
+look like this:
+
+```go
+type Queue[T any] struct {
+  data chan T
+}
+```
+
+This creates a type named `Queue` that takes a type argument `T`. This
+`T` can be absolutely anything, but the only requirement is that the
+data is a Go type.
+
+You can create a little constructor for `Queue` instances with a
+function like this:
+
+```go
+func NewQueue[T any](size int) Queue[T] {
+  return Queue[T]{
+    data: make(chan T, size),
+  }
+}
+```
+
+Now let's make some methods on the `Queue` struct that will let us
+push to the queue and pop from the queue. They could look like this:
+
+```go
+func (q Queue[T]) Push(val T) {
+  q.data <- val
+}
+
+func (q Queue[T]) Pop() T {
+  return <-q.data
+}
+```
+
+These methods will let you put data at the end of the queue and then
+pull it out from the beginning. You can use them like this:
+
+```go
+q := NewQueue[string](5)
+q.Push("hi there")
+str := q.Pop()
+if str != "hi there" {
+  panic("string is wrong")
+}
+```
+
+This is good, but the main problem comes from trying to pop from an
+empty queue. It'll stay there forever doing nothing. We can use the
+`select` statement to allow us to write a nonblocking version of the
+`Pop` function:
+
+```go
+func (q Queue[T]) TryPop() (T, bool) {
+  select {
+  case val := <-q.data:
+    return val, true
+  default:
+    return nil, false
+  }
+}
+```
+
+However when we try to compile this, we get an error:
+
+```
+cannot use nil as T value in return statement
+```
+
+In that code, `T` can be _anything_, including values that may not be
+able to be `nil`. We can work around this by taking advantage of the
+`var` statement, which makes a new variable and initializes it to the
+zero value of that type:
+
+```go
+func Zero[T any]() T {
+  var zero T
+  return zero
+}
+```
+
+When we run the `Zero` function like
+[this](https://go.dev/play/p/Z5tRs1-aKBU):
+
+```go
+log.Printf("%q", Zero[string]())
+log.Printf("%v", Zero[int]())
+```
+
+We get output that looks like this:
+
+```
+2009/11/10 23:00:00 ""
+2009/11/10 23:00:00 0
+```
+
+So we can adapt the `default` branch of `TryPop` to this:
+
+```go
+func (q Queue[T]) TryPop() (T, bool) {
+  select {
+  case val := <-q.data:
+    return val, true
+  default:
+    var zero T
+    return zero, false
+  }
+}
+```
+
+And finally write a test for good measure:
+
+```go
+func TestQueue(t *testing.T) {
+  q := NewQueue[int](5)
+  for i := range make([]struct{}, 5) {
+    q.Push(i)
+  }
+	
+  for range make([]struct{}, 5) {
+    t.Log(q.Pop())
+  }
+}
+```
+
+## `Option[T]`
+
+In Go, people use pointer values for a number of reasons:
+
+1. A pointer value may be `nil`, so this can signal that the value may
+   not exist.
+1. A pointer value only stores the offset in memory, so passing around
+   the value causes Go to only copy the pointer instead of copying the
+   value being passed around.
+1. A pointer value being passed to a function lets you mutate values
+   in the value being passed. Otherwise Go will copy the value and you
+   can mutate it all you want, but the changes you made will not
+   persist past that function call. You can sort of consider this to
+   be "immutable", but it's not as strict as something like passing
+   `&mut T` to functions in Rust.
+   
+This `Option[T]` type will help us model the first kind of constraint:
+a value that may not exist. We can define it like this:
+
+```go
+type Option[T any] struct {
+  val *T
+}
+```
+
+Then you can define a couple methods to use this container:
+
+```go
+var ErrOptionIsNone = errors.New("gonads: Option[T] has no value")
+
+func (o Option[T]) Take() (T, error) {
+  if o.IsNone() {
+    var zero T
+    return zero, ErrOptionIsNone
+  }
+
+  return *o.val, nil
+}
+
+func (o *Option[T]) Set(val T) {
+  o.val = &val
+}
+
+func (o *Option[T]) Clear() {
+  o.val = nil
+}
+```
+
+Some other functions that will be useful will be an `IsSome` function
+to tell if the `Option` contains a value. We can use this to also
+implement an `IsNone` function that will let you tell if that `Option`
+_does not_ contain a value. They will look like this:
+
+```go
+func (o Option[T]) IsSome() bool {
+  return o.val != nil
+}
+
+func (o Option[T]) IsNone() bool {
+  return !o.IsSome()
+}
+```
+
+We can say that if an Option does not have something in it, it has
+nothing in it. This will let us use `IsSome` to implement `IsNone`.
+
+Finally we can add all this up to a `Yank` function, which is similar
+to
+[`Option::unwrap()`](https://doc.rust-lang.org/rust-by-example/error/option_unwrap.html)
+in Rust:
+
+```go
+func (o Option[T]) Yank() T {
+  if o.IsNone() {
+    panic("gonads: Yank on None Option")
+  }
+
+  return *o.val
+}
+```
+
+This will all be verified in a Go test:
+
+```go
+func TestOption(t *testing.T) {
+  o := NewOption[string]()
+  val, err := o.Take()
+  if err == nil {
+    t.Fatalf("[unexpected] wanted no value out of Option[T], got: %v", val)
+  }
+    
+  o.Set("hello friendos")
+  _, err = o.Take()
+  if err != nil {
+    t.Fatalf("[unexpected] wanted no value out of Option[T], got: %v", err)
+  }
+    
+  o.Clear()
+  if o.IsSome() {
+    t.Fatal("Option should have none, but has some")
+  }
+}
+```
+
+<xeblog-conv name="Mara" mood="hmm">I think that
+<code>Option[T]</code> will be the most useful outside of this post.
+It will need some work and generalization, but this may be something
+that the Go team will have to make instead of some random
+person.</xeblog-conv>
+
+## `Thunk[T]`
+
+In computer science we usually deal with values and computations.
+Usually we deal with one or the other. Sometimes computations can be
+treated as values, but this is very rare. It's even more rare to take
+a partially completed computation and use it as a value.
+
+A thunk is a partially evaluated computation that is stored as a
+value. For an idea of what I'm talking about, let's consider this
+JavaScript function:
+
+```javascript
+const add = (x, y) => x + y;
+console.log(add(2, 2)); // 4
+```
+
+This creates a function called `add` that takes two arguments and
+returns one argument. This is great in many cases, but it makes it
+difficult for us to bind only one argument to the function and leave
+the other as a variable input. What if computing the left hand side of
+`add` is expensive and only needed once?
+
+Instead we can write `add` like this:
+
+```javascript
+const add = (x) => (y) => x + y;
+console.log(add(2)(2)); // 4
+```
+
+This also allows us to make partially evaluated forms of `add` like
+`addTwo`:
+
+```javascript
+const addTwo = add(2);
+console.log(addTwo(3)); // 5
+```
+
+This can also be used with functions that do not take arguments, so
+you can pass around a value that isn't computed yet and then only
+actually compute it when needed:
+
+```javascript
+const hypotenuse = (x, y) => Math.sqrt(x * x + y * y);
+const thunk = () => hypot(3, 4);
+```
+
+You can then pass this thunk to functions _without having to evaluate
+it_ until it is needed:
+
+```javascript
+dominateWorld(thunk); // thunk is passed as an unevaluated function
+```
+
+We can implement this in Go by using a type like the following:
+
+```go
+type Thunk[T any] struct {
+  doer func() T
+}
+```
+
+And then force the thunk to evaluate with a function such as `Force`:
+
+```go
+func (t Thunk[T]) Force() T {
+  return t.doer()
+}
+```
+
+This works, however we can also go one step further than we did with
+the JavaScript example. We can take advantage of the `Thunk[T]`
+container to cache the result of the `doer` function so that calling
+it multiple times will only actually it once and return the same
+result.
+
+<xeblog-conv name="Mara" mood="hacker">Keep in mind that this will
+only work for _pure functions_, or functions that don't modify the
+outside world. This isn't just global variables either, but any
+function that modifies any state anywhere, including network and
+filesystem IO.</xeblog-conv>
+
+This would make `Thunk[T]` be implemented like this:
+
+```go
+type Thunk[T any] struct {
+  doer func() T // action being thunked
+  o    *Option[T] // cache for complete thunk data
+}
+
+func (t *Thunk[T]) Force() T {
+  if t.o.IsSome() {
+    return t.o.Yank()
+  }
+    
+  t.o.Set(t.doer())
+  return t.o.Yank()
+}
+
+func NewThunk[T any](doer func() T) *Thunk[T] {
+  return &Thunk[T]{
+    doer: doer,
+    o:    NewOption[T](),
+  }
+}
+```
+
+Now, for an overcomplicated example you can use this to implement the
+Fibonacci function. We can start out by writing a naiive Fibonacci
+function like this:
+
+```go
+func Fib(n int) int {
+  if n <= 1 {
+    return n
+  }
+    
+  return Fib(n-1) + Fib(n-2)
+}
+```
+
+We can turn this into a Go test in order to see how long it takes for
+it to work:
+
+```go
+func TestRecurFib(t *testing.T) {
+  t.Log(Fib(40))
+}
+```
+
+Then when we run `go test`:
+
+```console
+$ go test -run RecurFib
+=== RUN   TestRecurFib
+    thunk_test.go:15: 102334155
+--- PASS: TestRecurFib (0.36s) 
+```
+
+However, we can make this a lot more complicated with the power of the
+`Thunk[T]` type:
+
+```go
+func TestThunkFib(t *testing.T) {
+  cache := make([]*Thunk[int], 41)
+  
+  var fib func(int) int
+  fib = func(n int) int {
+    if cache[n].o.IsSome() {
+      return *cache[n].o.val
+    }
+    return fib(n-1) + fib(n-2)
+  }
+  
+  for i := range cache {
+    i := i
+    cache[i] = NewThunk(func() int { return fib(i) })
+  }
+  cache[0].o.Set(0)
+  cache[1].o.Set(1)
+  
+  t.Log(cache[40].Force())
+}
+```
+
+And then run the test:
+
+```
+=== RUN   TestThunkFib
+    thunk_test.go:36: 102334155
+--- PASS: TestThunkFib (0.60s) 
+```
+
+<xeblog-conv name="Mara" mood="hmm">Why is this so much slower? This
+should be caching the intermediate values. Maybe something like this
+would be faster? This should complete near instantly,
+right?</xeblog-conv>
+
+```go
+func TestMemoizedFib(t *testing.T) {
+  mem := map[int]int{
+    0: 0,
+    1: 1,
+  }
+    
+  var fib func(int) int
+  fib = func(n int) int {
+    if result, ok := mem[n]; ok {
+      return result
+    }
+        
+    result := fib(n-1) + fib(n-2)
+    mem[n] = result
+    return result
+  }
+    
+  t.Log(fib(40))
+}
+```
+
+```console
+$ go test -run Memoized
+=== RUN   TestMemoizedFib
+    thunk_test.go:35: 102334155
+--- PASS: TestMemoizedFib (0.00s)
+```
+
+<xeblog-conv name="Cadey" mood="enby">I'm not sure
+either.</xeblog-conv>
+
+If you change the `fib` function to this, it works, but it also steps
+around the `Thunk[T]` type:
+
+```go
+fib = func(n int) int {
+  if cache[n].o.IsSome() {
+    return *cache[n].o.val
+  }
+  
+  result := fib(n-1) + fib(n-2)
+  cache[n].o.Set(result)
+  return result
+}
+```
+
+This completes instantly:
+
+```
+=== RUN   TestThunkFib
+    thunk_test.go:59: 102334155
+--- PASS: TestThunkFib (0.00s)
+```
+
+To be clear, this isn't the fault of Go generics. I'm almost certain
+that my terrible code is causing this to be much slower.
+
+<xeblog-conv name="Numa" mood="delet">This is the power of gonads:

+page](https://github.com/nix-community/NixOS-WSL/releases/) and download the
+`nixos-wsl-installer-fixed.tar.gz` file to your Downloads folder.
+
+Then open Powershell and make a folder called `WSL`:
+
+```powershell
+New-Item -Path .\WSL -ItemType Directory
+```
+
+<xeblog-conv name="Mara" mood="hacker">It's worth noting that Powershell does
+have a bunch of aliases for common coreutils commands to the appropriate
+Powershell CMDlets. However these aliases are <b>NOT</b> flag-compatible and use
+the Powershell semantics instead of the semantics of the command it is aliasing.
+This will bite you when you use commands like <code>wget</code> out of instinct
+to download things. In order to avoid your muscle memory betraying you, the
+Powershell CMDlets are shown here in their full overly verbose glory.
+</xeblog-conv>
+
+Then enter the directory with `Set-Location`:
+
+```powershell
+Set-Location -Path .\WSL
+```
+
+<xeblog-conv name="Mara" mood="hacker">This directory is where the NixOS root
+filesystem will live. If you want to put this somewhere else, feel free to.
+Somewhere in `%APPDATA%` will work, just as long as it's on an NTFS volume
+somewhere.
+</xeblog-conv>
+
+Make a folder for the NixOS filesystem:
+
+```powershell
+New-Item -Path .\NixOS -ItemType Directory
+```
+
+Then install the NixOS root image with the `wsl` command:
+
+```powershell
+wsl --import NixOS .\NixOS\ ..\Downloads\nixos-wsl-installer-fixed.tar.gz --version 2
+```
+
+And start NixOS once to have it install itself:
+
+```powershell
+wsl -d NixOS
+```
+
+Once that finishes, press control-D (or use the `exit` command) to exit out of
+NixOS and restart the WSL virtual machine:
+
+```powershell
+exit
+wsl --shutdown
+wsl -d NixOS
+```
+
+And then you have yourself a working NixOS environment! It's very barebones, but
+we can use it to test the `nix run` command against our gohello command:
+
+```console
+$ nix run github:Xe/gohello
+Hello reader!
+```
+
+## Local Services
+
+We can also use this NixOS environment to run a local nginx server. Open
+`/etc/nixos/configuration.nix`:
+
+```nix
+{ lib, pkgs, config, modulesPath, ... }:
+
+with lib;
+let
+  nixos-wsl = import ./nixos-wsl;
+in
+{
+  imports = [
+    "${modulesPath}/profiles/minimal.nix"
+
+    nixos-wsl.nixosModules.wsl
+  ];
+
+  wsl = {
+    enable = true;
+    automountPath = "/mnt";
+    defaultUser = "nixos";
+    startMenuLaunchers = true;
+
+    # Enable integration with Docker Desktop (needs to be installed)
+    # docker.enable = true;
+  };
+
+  # Enable nix flakes
+  nix.package = pkgs.nixFlakes;
+  nix.extraOptions = ''
+    experimental-features = nix-command flakes
+  '';
+}
+```
+
+Right after the `wsl` block, add this nginx configuration to the file:
+
+```nix
+services.nginx.enable = true;
+services.nginx.virtualHosts."test.local.cetacean.club" = {
+  root = "/srv/http/test.local.cetacean.club";
+};
+```
+
+This will create an nginx configuration that points the domain
+`test.local.cetacean.club` to the contents of the folder `/srv/http/test.local.cetacean.club`.
+
+<xeblog-conv name="Mara" mood="hacker">The <code>/srv</code> folder is set aside
+for site-specific data, which is code for "do whatever you want with this
+folder". In many cases people make a separate <code>/srv/http</code> folder and
+put each static subdomain in its own folder under that, however I am also told
+that it is idiomatic to put stuff in <code>/var/www</code>. Pick your poison.
+</xeblog-conv>
+
+Then you can test the web server with the `curl` command:
+
+```console
+$ curl http://test.local.cetacean.club
+<html>
+<head><title>404 Not Found</title></head>
+<body>
+<center><h1>404 Not Found</h1></center>
+<hr><center>nginx</center>
+</body>
+</html>
+```
+
+This is good! Nginx is running and since we haven't created the folder with our
+website content yet, this 404 means that it can't find it! Let's create the
+folder so that nginx has permission to it and we can modify things in it:
+
+```
+sudo mkdir -p /srv/http/test.local.cetacean.club
+sudo chown nixos:nginx /srv/http/test.local.cetacean.club
+```
+
+Finally we can make an amazing website. Open
+`/srv/http/test.local.cetacean.club/index.html` in nano:
+
+```
+nano /srv/http/test.local.cetacean.club/index.html
+```
+
+And paste in this HTML:
+
+```html
+<title>amazing website xD</title>
+<h1>look at my AMAZING WEBSITE</h1>
+It's so cool *twerks*
+```
+
+<xeblog-conv name="Mara" mood="hacker">This doesn't have to just be artisanal
+handcrafted HTML in bespoke folders either. You can set the <code>root</code> of
+a nginx virtual host to point to a Nix package as well. This will allow you to
+automatically generate your website somehow and deploy it with the rest of the
+system. Including being able to roll back changes.</xeblog-conv>
+
+And then you can see it show up with `curl`:
+
+```console
+$ curl http://test.local.cetacean.club
+<title>amazing website xD</title>
+<h1>look at my AMAZING WEBSITE</h1>
+It's so cool *twerks*
+```
+

+
+## Installing `gohello`
+
+To install the `gohello` service, first we will need to convert this machine to
+use NixOS flakes. We can do that really quick and easy by adding this file to
+`/etc/nixos/flake.nix`:
+
+<xeblog-conv name="Mara" mood="happy">Do this as root!</xeblog-conv>
+
+```nix
+{
+  inputs = {
+    nixpkgs.url = "nixpkgs/nixos-unstable";
+  };
+  
+  outputs = { self, nixpkgs, ... }: {
+    nixosConfigurations.nixos = nixpkgs.lib.nixosSystem {
+      system = "x86_64-linux";
+      modules = [
+        ./configuration.nix
+        
+        # add things here
+      ];
+    }; 
+  };
+}
+```
+
+Then run `nix flake check` to make sure everything is okay:
+
+```
+sudo nix flake check /etc/nixos
+```
+
+And finally activate the new configuration with flakes:
+
+```
+sudo nixos-rebuild switch
+```
+
+<xeblog-conv name="Mara" mood="hmm">Why don't you have the <code>--flake</code>
+flag here? Based on what I read in the documentation, I thought you had to have
+it there.</xeblog-conv>
+
+<xeblog-conv name="Cadey" mood="enby"><code>nixos-rebuild</code> will
+auomatically detect flakes in <code>/etc/nixos</code>. The only major thing it
+cares about is the hostname matching. If you want to customize the hostname of
+the WSL VM, change the <code>nixos</code> in
+<code>nixosConfigurations.nixos</code> above and set
+<code>networking.hostName</code> to the value you want to use. To use flakes
+explicitly, pass <code>--flake /etc/nixos#hostname</code> to your
+<code>nixos-rebuild</code> call. 
+</xeblog-conv>
+
+After it thinks for a bit, you should notice that nothing happened. This is
+good, we have just converted the system over to using Nix flakes instead of the
+classic `nix-channel` rebuild method.
+
+To get `gohello` in the system, first we need to add `git` to the commands
+available on the system in `configuration.nix`:
+
+```nix
+environment.systemPackages = with pkgs; [ git ];
+```
+
+Then we can add `gohello` to our system flake:
+
+```nix
+{
+  inputs = {
+    nixpkgs.url = "nixpkgs/nixos-unstable";
+    # XXX(Xe): this URL may change for you, such as github:Xe/gohello-http
+    gohello.url = "git+https://tulpa.dev/cadey/gohello-http?ref=main";
+  };
+
+  outputs = { self, nixpkgs, gohello, ... }: {
+    nixosConfigurations.nixos = nixpkgs.lib.nixosSystem {
+      system = "x86_64-linux";
+      modules = [
+        ./configuration.nix
+        
+        # add things here
+        gohello.nixosModule
+        ({ pkgs, ... }: {
+          xeserv.services.gohello.enable = true;
+        })
+      ];
+    }; 
+  };
+}
+```
+
+And rebuild the system with `gohello` enabled:
+
+```
+sudo nixos-rebuild switch
+```
+
+Finally, poke it with `curl`:
+
+```console
+$ curl http://gohello.local.cetacean.club
+hello world :)
+```
+
+To update it, update the flake inputs in `/etc/nixos` and run `nixos-rebuild`:
+
+```
+sudo nix flake update /etc/nixos
+sudo nixos-rebuild switch
+```
+
+---
+
+And from here you can do whatever you want with NixOS. You can use
+[containers](https://nixos.org/manual/nixos/stable/#ch-containers), set up
+arbitrary services, or plan for world domination as normal.
+
+<xeblog-conv name="Numa" mood="delet">I thought it was "to save the world from
+devastation", not "to plan for world domination". Who needs a monopoly on
+violence for world domination when you have Nix expressions?</xeblog-conv>
+
+<xeblog-conv name="Cadey" mood="coffee">Siiiiiiiiiiiiiiiiiigh.</xeblog-conv>
+
+I will use this setup in future posts to make this more accessible and easy to
+hack at without having to have a dedicated NixOS machine laying around.

+[Hey, you need to enable JavaScript for most of the embedded posts in this
+article to work. Sorry about this, we are working on a better solution, but this
+is what we have right now.](conversation://Mara/hacker)
+
+</noscript>
+
+What is art? Art is when you challenge the assumptions that people make about a
+medium and use that conflict to help them change what they think about that
+medium. Let's take "Comedian" by Maurizio Cattelan for example:
+
+![A banana duct-taped to an artist's
+canvas](https://cdn.christine.website/file/christine-static/blog/merlin_165616527_d76f38fc-e45d-4913-9780-1cc939750197-superJumbo.jpg)
+
+By my arbitrary definition above, this is art. This takes assumptions that you
+have about paintings (you know, that they use paint on the canvas) and discards
+them. This lets you change what you think art is. Art is not about the medium or
+the things in it. Art is the expression of these things in new and exiting ways.
+
+<xeblog-conv name="Cadey" mood="coffee">Originally I was going to use some
+Banksky art here, but for understandable reasons it's quite difficult to get
+images of Banksky art.</xeblog-conv>
+
+One of my favorite kinds of art is the "uncanny valley" of realism. Let's take
+Death Stranding as an example of this. Death Stranding is a video game that was
+released in 2019 for the PlayStation 4 and is one of my favorite games of all
+time. The game has a very hyper-realistic art style that is firmly in the
+centre of the uncanny valley:
+
+![A picture of Death Stranding gameplay, showing the protagonist Sam Porter
+Bridges attempting to climb a sheer cliff face using a rope that another player
+left
+behind](https://cdn.christine.website/file/christine-static/blog/20220202215156_3.jpg)
+
+This game mixes very realistic scenery with a story about dead bodies turning
+into antimatter and you being a UPS delivery person that saves America. This is
+art to me. This transformed what a video game could be, even if the entire game
+boils down to Kojima themed fetch quests. Oh and trying not to die even though
+you can't die but when you die it's really bad.
+
+I want to create this kind of art, and I think I have found a good medium to do
+this with. I write a lot on this little independent site called Twitter. This is
+one of the main things that I write on, and through the process of the last 8
+years or so, I've written a shockingly large amount of things. I post a lot of
+weird things there as well as a lot of boring/normal things.
+
+However a lot of my posts boil down to creating a "stream of consciousness", or
+using it as a way to help deal with intrusive thoughts. There's a certain art to
+this, as it is a candid exchange between the author and the reader. The reader
+doesn't get all the context (heck, I doubt that I have all the context lol), but
+from there they get to put the pieces together.
+
+So, when thinking about trying to get into the uncanny valley with this kind of
+art medium, my mind goes back to the old days on IRC channels. Many IRC channels
+run bots to help them run the channel or purely for amusement. One of my
+favorite kinds of bots is a [Markov
+chain](https://en.wikipedia.org/wiki/Markov_chain) bot. These kinds of bots
+learn patterns in text and then try to repeat them at random. With enough
+training data, it can be fairly convincing at first glance. However, you need _a
+lot_ of training data to get there. More training data than I have ever tweeted.
+
+This ends up creating a situation where the markov bot is right in the uncanny
+valley of realism. At first glance it is something that isn't not plausibly
+human. It looks like a bot, but it also looks like a human, but it also looks
+like a bot. It appears to be in the middle. I like this from an artistic
+standpoint because this challenges your assumptions that bots need to be
+obviously bots and humans need to be obviously human.
+
+In the past I have ran a service I call `cadeybot`. It took all of my Discord
+messages, fed them into a Markov chain, and then attempted to create new
+messages as a result. This worked pretty well, but we ran into an issue where it
+would basically regurgitate its training data. So when people thought it was
+being novel about roasting people, someone would search the chat and find out
+that I said those exact words 2 years ago.
+
+This isn't really exciting from an artistic point of view. You could get the
+same result from randomly replying with old chat messages without any additional
+data in the mix.
+
+I haven't run `cadeybot` in some time because of this. It gets really boring
+really fast.
+
+However, I was looking at some DALL-E generated images and then inspiration
+struck:
+
+<xeblog-conv name="Mara" mood="hmm">What if I fed all those tweets into
+[GPT-2](https://en.wikipedia.org/wiki/GPT-2)?</xeblog-conv>
+
+So I did that. I made [@robocadey@botsin.space](https://botsin.space/@robocadey)
+as a fediverse bot that generates new content based on everything I've ever
+tweeted.
+
+<iframe src="https://botsin.space/@robocadey/108219835651549836/embed"
+class="mastodon-embed" style="max-width: 100%; border: 0" width="500"
+height="245" allowfullscreen="allowfullscreen"></iframe>
+
+## Data
+
+The first step of this is getting all of my tweet data out of Twitter. This
+was a lot easier than I thought. All I had to do was submit a GDPR data request,
+wait a few days for the cloud to think and then I got a 3 gigabyte zip file full
+of everything I've ever tweeted. Cool!
+
+Looking through the dump, I found a 45 megabyte file called `tweets.js`. This
+looked like it could be important! So I grabbed it and looked at the first few
+lines:
+
+```javascript
+$ head tweet.js
+window.YTD.tweet.part0 = [
+  {
+    "tweet" : {
+      "retweeted" : false,
+      "source" : "<a href=\"http://www.bitlbee.org/\" rel=\"nofollow\">BitlBee</a>",
+      "entities" : {
+        "hashtags" : [ ],
+        "symbols" : [ ],
+        "user_mentions" : [
+          {
+```
+
+So it looks like most of this is really just a giant block of data that's
+stuffed into JavaScript so that the embedded HTML can show off everything you've
+ever tweeted. Neat, but I only need the tweet contents. We can strip off the
+preamble with `sed`, and then grab the first entry out of `tweets.js` with a
+command like this:
+
+```json
+$ cat tweet.js | sed 's/window.YTD.tweet.part0 = //' | jq .[0]
+{
+  "tweet": {
+    "retweeted": false,
+    "source": "<a href=\"http://www.bitlbee.org/\" rel=\"nofollow\">BitlBee</a>",
+    "entities": {
+      "hashtags": [],
+      "symbols": [],
+      "user_mentions": [
+        {
+          "name": "@Lyude@queer.party🌹",
+          "screen_name": "_Lyude",
+          "indices": [
+            "0",
+            "7"
+          ],
+          "id_str": "1568160860",
+          "id": "1568160860"
+        }
+      ],
+      "urls": []
+    },
+    "display_text_range": [
+      "0",
+      "83"
+    ],
+    "favorite_count": "0",
+    "in_reply_to_status_id_str": "481634023295709185",
+    "id_str": "481634194729488386",
+    "in_reply_to_user_id": "1568160860",
+    "truncated": false,
+    "retweet_count": "0",
+    "id": "481634194729488386",
+    "in_reply_to_status_id": "481634023295709185",
+    "created_at": "Wed Jun 25 03:05:15 +0000 2014",
+    "favorited": false,
+    "full_text": "@_Lyude but how many licks does it take to get to the centre of a tootsie roll pop?",
+    "lang": "en",
+    "in_reply_to_screen_name": "_Lyude",
+    "in_reply_to_user_id_str": "1568160860"
+  }
+}
+```
+
+It looks like most of what I want is in `.tweet.full_text`, so let's make a
+giant text file with everything in it:
+
+```sh
+sed 's/window.YTD.tweet.part0 = //' < tweets.js \
+  | jq '.[] | [ select(.tweet.retweeted == false) ] | .[].tweet.full_text' \
+  | sed -r 's/\s*\.?@[A-Za-z0-9_]+\s*//g' \
+  | grep -v 'RT:' \
+  | jq --slurp . \
+  | jq -r .[] \
+  | sed -e 's!http[s]\?://\S*!!g' \
+  | sed '/^$/d' \
+  > tweets.txt
+```
+
+This does a few things:
+
+1. Removes that twitter preamble so jq is happy
+2. Removes all at-mentions from the training data (so the bot doesn't go on a
+   mentioning massacre)
+3. Removes the "retweet" prefixed tweets from the dataset
+4. Removes all urls
+5. Removes all blank lines
+
+This should hopefully cut out all the irrelevant extra crap and let the machine
+learning focus on my text, which is what I actually care about.
+
+## Getting It Up
+
+As a prototype, I fed this all into Markov chains. This is boring, but I was
+able to graft together a few projects to get that prototype up quickly. After
+some testing, I ended up with things like this:
+
+<iframe src="https://botsin.space/@robocadey/108201675365283068/embed"
+class="mastodon-embed" style="max-width: 100%; border: 0" width="500"
+height="225" allowfullscreen="allowfullscreen"></iframe>
+
+This was probably the best thing to come out of the Markov chain testing phase,
+the rest of it was regurgitating old tweets.
+
+While I was doing this, I got GPT-2 training thanks to [this iPython
+notebook](https://colab.research.google.com/github/sarthakmalik/GPT2.Training.Google.Colaboratory/blob/master/Train_a_GPT_2_Text_Generating_Model_w_GPU.ipynb).
+I uploaded my 1.5 megabyte tweets.txt file and let the big pile of linear
+algebra mix around for a bit.
+
+Once it was done, I got a one gigabyte tarball that I extracted into a new
+folder imaginatively named `gpt2`. Now I had the model, all I needed to do was
+run it. So I wrote some Python:
+
+```python
+#!/usr/bin/env python3
+
+import gpt_2_simple as gpt2
+import json
+import os
+import socket
+import sys
+from datetime import datetime
+
+sockpath = "/xe/gpt2/checkpoint/server.sock"
+
+sess = gpt2.start_tf_sess()
+gpt2.load_gpt2(sess, run_name='run1')
+
+if os.path.exists(sockpath):
+    os.remove(sockpath)
+
+sock = socket.socket(socket.AF_UNIX)
+sock.bind(sockpath)
+
+print("Listening on", sockpath)
+sock.listen(1)
+
+while True:
+    connection, client_address = sock.accept()
+    try:
+        print("generating shitpost")
+        result = gpt2.generate(sess,
+                    length=512,
+                    temperature=0.8,
+                    nsamples=1,
+                    batch_size=1,
+                    return_as_list=True,
+                    top_p=0.9,
+                    )[0].split("\n")[1:][:-1]
+        print("shitpost generated")
+        connection.send(json.dumps(result).encode())
+    finally:
+        connection.close()
+
+server.close()
+os.remove("/xe/gpt2/checkpoint/server.sock")
+```
+
+And I used a Dockerfile to set up its environment:
+
+```Dockerfile
+FROM python:3
+RUN pip3 install gpt-2-simple
+WORKDIR /xe/gpt2
+COPY . .
+CMD python3 main.py
+```
+
+Then I bind-mounted the premade model into the container and asked it to think
+up something for me. I got back a list of replies and then I knew it was good to
+go:
+
+```json
+[
+  "oh dear. I don't know if you're the best mannered technologist you've come to expect from such a unique perspective.

+  "The main thing I am trying to do is make it easy to type backwards. This is going to take experimentation. I am trying to make it slightly different sounding.",
+  "Is this vehicle of mercy?",

+
+However, this involved using Docker. Docker is decent, but if I have the ability
+not to, I don't want to use Docker. A friend of mine named `ckie` saw that I was
+using Docker for this and decided to package the `gpt_2_simple` library [into
+nixpkgs](https://github.com/NixOS/nixpkgs/pull/170713). They also made it easy
+for me to pull it into robocadey's environment and then I ripped out Docker,
+never to return.
+
+Now the bot could fly. Here was the first thing it posted after it got online
+with GPT-2 in a proper way:

+If you want to influence `robocadey` into giving you an artistic experience,

+It will think a bit and then reply with a brand new post for you.
+
+## Setting It Up
+
+You probably don't want to do this, but if you're convinced you do then here's
+some things that may help you.
+
+1. Use the systemd units in `/run` of [github:Xe/x](https://github.com/Xe/x).
+2. Put your model into a squashfs volume that you mount to the
+   `/var/lib/private/xeserv.robocadey-gpt2/checkpoint` folder.
+3. Don't expect any warranty, reliability promises or assistance setting this
+   up. I made this for myself, not for others. Its source code is made available
+   to make the code part of that art, but the code is not the art that it makes.
+
+Good luck.
+
+---
+
+I guess what I think about art is that it's not just the medium. It's not just
+the expression. It's the combination of it all. The expression, the medium, the
+circumstances, all of that leads into what art really is. I could say that art
+is the intangible expressions, emotions, and whatever that you experience when
+looking at things; but that sounds really really pretentious, so let's just say
+that art doesn't exist. Well it does, but only in the mind of the viewer.
+
+There's not some objective scale that can say that something is or is not an
+art. Art is imagined and we are conditioned to believe that things are or are
+not art based on our upbringing.
+
+I feel that as a shitposter my goal is to challenge people's "objective sense"
+of what "can" and "can't" be art by sitting right in the middle of the two and
+laughing. Projects like `robocadey` are how I make art. It's like what 200 lines
+of code at most. You could probably recreate most of it based on the contents of
+this post alone. I wonder if part of the art here comes from the fact that most
+of this is so iterative yet so novel. Through the iteration process I end up
+creating novelty.
+
+You could also say that art is the antidote to the kind of suffering that comes
+from the fundamental dissatisfactions that people have with everyday life. By
+that defintion, I think that `robocadey` counts as art.
+
+Either way, it's fun to do these things. I hope that this art can help inspire
+you to think differently about the world. Even though it's through a chatbot
+that says things like this:

+height="200" allowfullscreen="allowfullscreen"></iframe>
+
+What is this if not art?

+title: "Twitter, Mastodon and The Parable of rasengan"
+date: 2022-04-25
+tags:
+ - twitter
+ - reaction
+---
+
+So a lot of things happened today. The threat that Elon Musk made to
+buy Twitter seems to have been true. As I write this, my current
+understanding is that the Twitter board of directors is in the process
+of accepting the offer that Elon Musk to buy the company.
+
+<xeblog-conv name="Cadey" mood="coffee">This was not on my bingo card
+for 2022. I'm starting to think that I got a dud bingo card. I was
+hoping that "Alien Invasion" would win out but it looks like that
+won't be the case yet. Damn.</xeblog-conv>
+
+I genuinely have no idea how I should be reacting to this news. I
+spend a lot of time on Twitter. It's a lot of how I talk with people,
+network in the tech community and generally shitpost. I do so much
+idle shitposting on Twitter that it would probably count for a lot of
+the non-work written word I produce on a weekly basis.
+
+I'm really not sure what I feel about this, but the feelings that I am
+getting remind me of [what happened to
+freenode](/blog/series/freenode). A while ago someone I follow on
+Twitter made a tweet that said something like:
+
+> Elon Musk is to Twitter as rasengan is to freenode
+
+<xeblog-conv name="Mara" mood="hacker">For context: rasengan is the
+person that single-handedly destroyed freenode by apparently buying a
+worthless holding company and then inciting a lot of
+drama. For more information, check out the book Closed
+Projects.</xeblog-conv>
+
+I have made my book [Closed
+Projects](/blog/closed-projects-2022-03-24) free for the next week.
+This contains my moods, reactions and emotions as I was processing
+everything falling apart around me. I feel this may help you
+understand the emotions that you get watching this shitshow unfold
+with Twitter.
+
+For a direct link to the sale page, click
+[here](https://itch.io/s/69916/elon-bought-twitter-sale). I will
+donate proceeds from this sale to charity. If you choose to send me a
+couple bucks for my book, I will donate them to the [Orca
+Conservancy](https://www.orcaconservancy.org/).
+
+I am also on Mastodon at
+[@cadey@pony.social](https://pony.social/@cadey). Should something
+happen to Twitter such that I can't participate there anymore, I will
+be on Mastodon. If Twitter really starts falling apart, I will
+probably be a lot more active on Mastodon. And probably writing a lot
+more.
+
+Let's hope things turn out well.
