Berkeley Logo has higher order mapping functions like "cascade" and "crossmap" which I miss in modern Emacs Lisp with its countless packages for example. If you want something more fancier, NetLogo provides agent based p

You lucky! My kid's school teaches Delphi/TurboPascal (8. grade, first programming language course), which they replaced with Lazarus unable to install Delphi on modern PCs.

It's not GPU, it's called RIP - Raster Image Processor. And yes, one of the benefits of print is, that it is already pre-rendered. Waiting for a PDF reader/browser to show a complex vector image is just annoying.

What is this mass psychosis of feeling the urge to own a dog or cat anyway? And how it comes, that environmentalists don't get loud on the harm on nature caused by domestic cats and dogs?

This is how socialism "works". One pays enormous taxes his whole life, but then, when it comes for government to protect one's health, they do nothing and name this even "liberal".

So, there are ventilators sitting around useless, because there may be needed "in a week or two" and the EU is not able to organize and coordinate the JIT dirstribution of the equipment across the countries?

I tried to explain recursion to my son with the monks from "Towers of Hanoi": What is a monk handing out to the next one? Is he waiting? What is a monk's contribution to the answer? How many monks do we need? What does the la

Berkeley Logo (brand new in version 6.1). I have compiled two versions, with and without wx. The file with the procedures is on github: https://github.com/pgtan/puzzles/blob/master/baum1.lg https:/

But it is also a excellent concatenative (left-to-right) language with brilliant procedure definition mechanism. Here as example, an oneliner to draw ascii christmas tree, we made with the kid last year: ? tanne.print tanne.output tanne.s

I see LOGO also as a kind of (lispy, interactive, left to right!) concatenative langugage. Here is an example, an ASCII christmass tree we made with the kid recently: ? tanne.print tanne.output tanne.shift tanne.split 19 3 3

Yes, LOGO already has all the list evaluating like the real Lisp. ? run `[print ,[sum 2 3]] 5 But also a very sophisticated way to define functions with many default and within even optional parameters without the need of parentheses . Fro

LOGO is already Lisp without parentheses and with infix notation. Recently, doing exercises in LOGO with my kid,he asked: can we put some parentheses around the functions for better clearness? I said: my son, you just discovered Lisp!

Prolog gives you backtracking for free and liberates you from loops and if's.

Even simple thing like drawing the Euler spiral has much more effect, if you visualize the turtle motion, so you can see how the motion turns at some point and the turtle starts going back on the same way down. cs repeat 360 [fd 10 lt produ

For me, COBOL is so over-presented in the media among the old (mainframe) lagnuages, but I recently was surprised to see a production mainframe LPAR offering an APL2 interface,and it seems the language is still maintained on zOS[1]. But I n
