#introducion I'm an unemployed Python backend developer and today I have ended up spending the whole day:

  1. watching some tutorial videos about GNU Guix (powered by Guile Scheme)
  2. reading/bookmarking random articles about Scheme/Lisp (still don't understand what is the difference, but Scheme seems to be newer and standardized)
  3. remembering/learning again how to code in Logo — my very first programming language, which happens to be based on lisp; 10 years ago I hadn't realized that "var is a plain string literal and :var is a syntactic sugar for (thing "var)
  4. reading about various Logo implementations
  5. figuring out how to export images from ucblogo and trying to avoid crashes (don't use label if you export image with epspict; and don't press random keys if you don't wanna get segmentation fault O_o)
  6. writing a bash script to convert *.lg program into *.png (feat. sed and ImageMagick)

I forgot to go to the store to buy some food before it was too late, so now I'm hungry... But in return I have a picture... of something.

If you know Logo, why not share some random #turtleGraphics #art

make "t 0
repeat 18 [
rt 20
repeat 3 [
rt 20
repeat 10 [
make "t :t + 1
setpencolor (list
(1 + cos (:t / 3)) * 50
(1 + sin (:t / 2)) * 50
:t / 7
)
fd 10
rt 10

@th Very nice! 😊 Sadly I never came across Logo in real life

At first glance, it seems a strangely domain-specific language to use to teach programming

And yet I can see that what it does at that level is far more interesting than arguably equally domain-specific languages like BASIC

(Any language whose standard beginner’s example is of the hello-world type is at least geared towards text processing, and on the first computers I used, all graphics were made out of text)

Side note: TIL that Logo is the same age as me (el.media.mit.edu/logo-foundati)

el.media.mit.eduLogo Foundation

Mai avrei pensato di "appassionarmi" a LOGO a quasi quarant'anni 😅
Se solo la prof. delle medie non fosse stata così terribilmente noiosa 🤣

Due MOOC molto interessanti.

"Coding a scuola con Software Libero

Impara come usare il coding per l'apprendimento della matematica, delle arti e della grammatica."
