Mikael: Let's write a scheme program which randomly makes names by
combining two words from a list.

To write a Scheme program that generates random names by combining two
words from a list, you can use the following code:

scheme

(import (scheme random)) ; Import random number generation functions

(define word-list '("Alpha" "Beta" "Gamma" "Delta" "Epsilon" "Zeta"
"Eta" "Theta" "Iota" "Kappa"))

(define (random-word lst)
  (list-ref lst (random (length lst))))

(define (random-name)
  (string-append (random-word word-list) (random-word word-list)))

(random-name)

In this program, we:

   1. Import the random number generation functions from the (scheme random)
   library.
   2. Define a word-list containing words that will be used to generate
   random names.
   3. Create a function random-word that takes a list as an argument and
   returns a random element from that list.
   4. Create a function random-name that combines two random words from the
   word-list using string-append.
   5. Call random-name to generate a random name.

You can run this code in a Scheme interpreter or REPL (Read-Eval-Print
Loop) to generate random names.

Mikael: Great! Can you adapt it for Guile scheme?

Sure! Here's the adapted code for Guile Scheme:

scheme

(use-modules (ice-9 random)) ; Import random number generation
functions for Guile

(define word-list '("Alpha" "Beta" "Gamma" "Delta" "Epsilon" "Zeta"
"Eta" "Theta" "Iota" "Kappa"))

(define (random-word lst)
  (list-ref lst (random (length lst))))

(define (random-name)
  (string-append (random-word word-list) (random-word word-list)))

(random-name)

In this Guile Scheme version, we:

   1. Replace the (import (scheme random)) statement with (use-modules
   (ice-9 random)) to import random number generation functions in Guile
   Scheme.
   2. The rest of the code remains the same as the original Scheme version.

You can run this code in a Guile Scheme interpreter or REPL to generate
random names.

Mikael: Now let's use the words doodle, puck, bongo, foo, bar zoinc instead.

Here's the Guile Scheme code using the new words you provided:

scheme

(use-modules (ice-9 random)) ; Import random number generation
functions for Guile

(define word-list '("doodle" "puck" "bongo" "foo" "bar" "zoinc"))

(define (random-word lst)
  (list-ref lst (random (length lst))))

(define (random-name)
  (string-append (random-word word-list) (random-word word-list)))

(random-name)

The only change made to the original code is updating the word-list with
the new words you've provided. The rest of the code remains the same. You
can run this updated code in a Guile Scheme interpreter or REPL to generate
random names using the new words.
Mikael: Can you execute (random-name)?

As an AI text-based model, I am unable to directly execute code in a REPL
environment. However, I can help you understand how to run the provided
code.

To run the provided Guile Scheme code and execute (random-name), you can
follow these steps:

   1.

   Install Guile on your computer if you haven't already. You can find
   installation instructions here:
   https://www.gnu.org/software/guile/download/
   2.

   Copy and paste the provided code into a text editor, and save it as a
   file named random-name.scm.
   3.

   Open a terminal or command prompt, and navigate to the directory where
   you saved the random-name.scm file.
   4.

   Run the following command in the terminal or command prompt: guile -s
   random-name.scm

This command will execute the Guile Scheme code in the random-name.scm file
and print a random name using the words from the word-list. Each time you
run the command, you will get a new random name as the output.[image:
mikael@djurfeldt.com]
Mikael: Can you give one example of how the result would look like?

Certainly! When you execute the provided Guile Scheme code using the given
word list, you may get different random names each time you run it. Here's
one possible example of a random name generated using the words in the
word-list:

doodlebongo

In this example, the program has combined the words "doodle" and "bongo" to
create a new random name. Keep in mind that you will get different results
each time you run the program, as the name generation is random.

Can you write a Guile Scheme program which displays a bouncing ball?

As an AI language model, I cannot create a full graphical program directly
within this text-based environment. However, I can provide you with an
example of a simple bouncing ball simulation using the Guile Scheme
programming language and the SDL2 (Simple DirectMedia Layer) library, which
is commonly used for creating graphical applications.

To start, you'll need to have Guile and the Guile-SDL2 bindings installed.
The following instructions are for a Debian-based system:

   1. Install Guile:

csharp

sudo apt-get install guile-2.2


   1. Install SDL2 development libraries:

csharp

sudo apt-get install libsdl2-dev libsdl2-image-dev libsdl2-ttf-dev


   1. Clone and build the Guile-SDL2 library:

bash

git clone https://github.com/davexunit/guile-sdl2.gitcd guile-sdl2
autoreconf -vif
./configure
make
sudo make install

Now you can create the bouncing ball program in a file called
bouncing-ball.scm:

scheme

(use-modules (sdl2)
             (sdl2 video)
             (sdl2 events)
             (sdl2 timer)
             (sdl2 rect))

(define screen-width 640)
(define screen-height 480)
(define ball-size 20)

(define ball-x (make-parameter (/ (- screen-width ball-size) 2)))
(define ball-y (make-parameter (/ (- screen-height ball-size) 2)))
(define ball-x-velocity (make-parameter 4))
(define ball-y-velocity (make-parameter 4))

(define (process-events)
  (let loop ((event (poll-event)))
    (when event
      (case (event-type event)
        ((quit) #f)
        (else (loop (poll-event)))))))

(define (update-ball)
  (parameterize ((x (ball-x))
                 (y (ball-y))
                 (vx (ball-x-velocity))
                 (vy (ball-y-velocity)))
    (ball-x (+ x vx))
    (ball-y (+ y vy))

    (when (or (<= (+ x vx) 0) (>= (+ x vx ball-size) screen-width))
      (ball-x-velocity (- vx)))

    (when (or (<= (+ y vy) 0) (>= (+ y vy ball-size) screen-height))
      (ball-y-velocity (- vy)))))

(define (draw-ball renderer)
  (let ((ball-rect (make-rect (ball-x) (ball-y) ball-size ball-size)))
    (set-render-draw-color renderer 255 0 0 255)
    (render-fill-rect renderer ball-rect)))

(define (main)
  (init! +init-video+)
  (let ((window (create-window "Bouncing Ball" +window-pos-undefined+
+window-pos-undefined+ screen-width screen-height +window-shown+))
        (renderer (create-renderer window -1 +renderer-accelerated+)))
    (set-render-draw-color renderer 0 0 0 255)
    (let loop ()
      (unless (process-events)
        (update-ball)
        (render-clear renderer)
        (draw-ball renderer)
        (render-present renderer)
        (delay 16)
        (loop)))))

(main)

This example sets up a window using SDL2 and creates a simple ball that
bounces off the edges of the window. You can run the program using the
following command:

bash

guile bouncing-ball.scm

Keep in mind that this is a simple example, and there are many ways to
improve or expand upon it, such as using images

Apologies for the confusion. It seems I made a mistake in the provided
code, and some symbols were not correctly imported. Let's fix the imports
by using the appropriate modules and functions. Replace the (use-modules
...) line in the code with the following:

scheme

(use-modules (sdl2) (sdl2 video) (sdl2 events) (sdl2 timer) (sdl2
rect) (sdl2 rwops) (sdl2 surface) (sdl2 sdl))

Additionally, it seems that the init! function is not being recognized. It
should be SDL_Init instead. So, replace the line (init! +init-video+) with:

scheme

(SDL_Init +SDL_INIT_VIDEO+)

After making these changes, the updated bouncing-ball.scm should look like
this:

scheme

(use-modules (sdl2)
             (sdl2 video)
             (sdl2 events)
             (sdl2 timer)
             (sdl2 rect)
             (sdl2 rwops)
             (sdl2 surface)
             (sdl2 sdl))

(define screen-width 640)
(define screen-height 480)
(define ball-size 20)

(define ball-x (make-parameter (/ (- screen-width ball-size) 2)))
(define ball-y (make-parameter (/ (- screen-height ball-size) 2)))
(define ball-x-velocity (make-parameter 4))
(define ball-y-velocity (make-parameter 4))

(define (process-events)
  (let loop ((event (poll-event)))
    (when event
      (case (event-type event)
        ((quit) #f)
        (else (loop (poll-event)))))))

(define (update-ball)
  (parameterize ((x (ball-x))
                 (y (ball-y))
                 (vx (ball-x-velocity))
                 (vy (ball-y-velocity)))
    (ball-x (+ x vx))
    (ball-y (+ y vy))

    (when (or (<= (+ x vx) 0) (>= (+ x vx ball-size) screen-width))
      (ball-x-velocity (- vx)))

    (when (or (<= (+ y vy) 0) (>= (+ y vy ball-size) screen-height))
      (ball-y-velocity (- vy)))))

(define (draw-ball renderer)
  (let ((ball-rect (make-rect (ball-x) (ball-y) ball-size ball-size)))
    (set-render-draw-color renderer 255 0 0 255)
    (render-fill-rect renderer ball-rect)))

(define (main)
  (SDL_Init +SDL_INIT_VIDEO+)
  (let ((window (create-window "Bouncing Ball" +window-pos-undefined+
+window-pos-undefined+ screen-width screen-height +window-shown+))
        (renderer (create-renderer window -1 +renderer-accelerated+)))
    (set-render-draw-color renderer 0 0 0 255)
    (let loop ()
      (unless (process-events)
        (update-ball)
        (render-clear renderer)
        (draw-ball renderer)
        (render-present renderer)
        (delay 16)
        (loop)))))

(main)

Now, the program should run without any issues. Run it with:

bash

guile bouncing-ball.scm

I think it should be make-window instead of create-window.

You are correct. The function should be make-window instead of create-window.
I apologize for the confusion. Here's the updated bouncing-ball.scm code
with the corrected function name:

    (ball-y (+ y vy))

    (when (or (<= (+ x vx) 0) (>= (+ x vx ball-size) screen-width))

Re: GPT-4 knows Guile! :)

i understand the fun thing... :-)

and i did not check the program with Guile but asked a Racket version of
the bouncing ball and it is full of errors even if i try to correct them by
hand...

Welcome to DrRacket, version 8.7 [cs].
Language: racket/gui, with debugging; memory limit: 8192 MB.
. . send: no such method
  method name: register-event-callback
  class name: canvas%


after i asked this question to chatGPT:

"Can you write a Guile Scheme program that put a logical expression in
minimal disjunctive normal form?"

i got a truncated program trying to code a QuineMcCluskey algorithm
implementation that i can not redisplay here because i got a connection
error to server and that looked like a bit,but from very very very far away
my own logic code in github that i spend many years to wrote,

and the Chat finished  like this:

"Hmm...something seems to have gone wrong. Maybe try me again in a little
bit"

:-)

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.

and my conclusion is chatGPT is a very bad student that does not know the
difference between a Scheme procedure and a special form :-)

and the 65lines chatGPT code is far from my > 5000 lines code to minimize
in disjunctive normal forms.......

but you will continue to read a lot of newspaper saying AI is able to write
programs....

chatGPT is only a "predictor of the next word" ,okay perheaps a bit more....

Did it literally write "csharp"? With some fantasy, I guess it
is trying to evoke a root shell, but with some malice, I'd say
Microsoft is sleazily touting some product of theirs.

No, in the browser the bash lines were presented in windows which had the
text "bash" in the title bar, but GPT-4 is a bit sloppy in that text can
"leak in" from other documents, so the first two windows had the title
csharp instead of bash. When I then just marked a region in the browser and
copied, the text from the title windows got copied too (and *I*, being a
bit sloppy, didn't notice it :).

"from other documents" is bad wording. Of course this is fundamentally a
neural representation which is inherently a bit fuzzy.

Actually, I think those were associating the convention of suggesting
a root shell prompt by a '#', aka a "sharp sign". Given the flooding
of ghithub with csharp, the thing probably dreamt up the "c" before
the "sharp". Note that those are exactly the two lines you would
execute as root (not that I would ever execute a command suggested
by ChatGPT as root,mind you).

This is what I was hinting at with that pastiche of Hanlon's Razor
and Clarke's Third Law. If you're doing statistical "AI", no harm
is provably intended. But the dice might be loaded ;-)

BTW, in the bouncing ball example, I find it amazing that I could get an
improvement of the code by complaining:

But all those SDL_ calls look like C bindings. Please use guile-sdl2
bindings.

(It was also quite entertaining that I had to ask it to write the code

Perhaps you didn't know, but you are training the model :-)

This is called gamification, latest known in early 2000s. Luis von
Ahn [1] did quite a bit of pioneering work in that (he called it
"human computation", his PhD was "Games With a Purpose", Google
licensed a game from him to make people "out there" tag images for
them.

So I'd say this is established "technology".

Unfortunately not. I'm prompting it within its 32000 token (GPT-4)
attention span. Next conversation the model is back to exactly the same
state again. Then, of course, it is possible that OpenAI chooses to filter
out something from the dialogs it has had.

So, a trick you can do is to start out every session with a standard set of
prompts (like "keep it short" or whatever) which will then act as a kind of
configuration.

You don't think that those coversations end up as raw data for the
next model? I'd be surprised, but you know definitely more than me.

I know very little apart from knowing what deep learning is and having
skimmed the "Attention is all you need"-paper. I only meant that you are
not training the model during and between sessions. It is certainly
possible that OpenAI filters out things from the dialogs to use as part of
training for the next version. They warn you that they may take data from
the dialogs. If and how they do that I don't know.

Mikael

Or, as GPT-4 would phrase it: I apologize for the confusion in my previous
answer. You may be right that I'm training the next version of the model. :)

chatGPT is using the "static" 2021 free data available on internet ,free
databases,...  it knows poorly after 2021 as "they" say.

Without the human intelligence that has create all the data chatGPT can do
nothing.

Now people use chatGPT to create poor quality data stored on the  internet
web page instead of making the web page content by intelligent humans. In
the next release of chatGPT it will use those new "poor data" in its
training data set  to deliver answers of lesser quality again.

Also:

do you have a mechanism to avoid controversy

As an AI language model, I am designed to prioritize providing accurate and
helpful information while aiming to be neutral and unbiased. My developers
at OpenAI have implemented guidelines to help me avoid generating content
that is offensive, harmful, or excessively controversial. However, I am not
perfect, and there might be cases where my responses could unintentionally
touch upon controversial topics or express unintended biases.

To minimize these issues, I rely on the vast amount of data I have been
trained on, which includes diverse perspectives and opinions. I aim to
provide balanced and informative responses based on this training.

If you believe my response is inappropriate or controversial, please let me
know, and I will do my best to provide a more suitable answer.
Additionally, your feedback helps me improve and refine my responses over
time.

That's already more than I do, I think. Thanks for the pointer :)

No, I don't think we are yet at "real time model training". But who knows.

I'm pretty sure that this is the plan (besides, of course, of trying to
assess, understand public reaction to the whole idea, and perhaps to
steer public perception, as far as possible).

I replaced google with chatGPT and it's really good to help with issues you
have in your work. As an example our IT department stopped us from
installing eclipse plugins from the marketplace and I was just lost getting
no help from googling. So I just asked ChatGpt how to install gradle
without using the marketplace and got a perfect answer that was of such
good quality that I pasted it into our dev guides. If you want to know how
to do something you get a good start by asking ChatGpt but it's not that
good at writing code yet. Asking it for code review of small code portions
is also useful. It's also fantastic at explaining how things work and a
very good tool for learning stuff. Learning how to use ChatGpt to improve
your code quality and productivity is how we should approach it. And the
more experienced you are, the more effective use you will have of it.

Hi Stefan,

Interesting to hear these experiences. I'm sure there will be a period now
when people discover further and further use cases. It seems to be a
revolutionizing tool.

Best regards,
Mikael

The stench of Microsoft [1] is just too unsupportable to me. Luckily
I'm old and hope to be soon out-of-market anyway.

Yes, this is an important point. And it is sometimes possible to see a bias
in the OpenAI engines towards what texts (and thus opinions) that are
commonly occuring on the internet.

I reflected a bit on its genesis. It started while working deep
in a big company's belly -- I observed that, while the majority
of the people working in there where nice persons, the whole had
something evil in its behaviour and actions. There I came up with
the concept of "emergent evil", like the emergent behaviour you
might observe in an anthill.

While pondering this, I further realised that higher management's
job was to actually steer this emergent behaviour, and came to
the conclusion that a higher manager wasn't worth its salt if
(s)he didn't master this skill (and wouldn't probably stay at
this job). Whether that happens consciously or unconciously.

Mix in some plausible deniability ("steer", not "do"), and that
pastiche came up.

Cheers
