The end of the Prologue to HtDP2e ends with a section titled You Are a Programmer Now. If you have read it you know what it contains (if you haven't read it then you are not likely able to respond intelligently to this question). My question is: in that section are the authors describing "progr

(Actually, I bought the book and was just working through the Prologue today. And didn't turn the page, it appears. ) Thank you for your response. More specifically, what I was referring to was a response that has gotten a fair bit of circulation given by Gerry Sussman when asked why SICP was n

The idea that we need to deal with software systems as if we were natural scientists shows up time and again. Gerry is correct about this but this does not mean we should not teach good attitudes about code and coding etc. ;; - - - As far as I am concerned, SiCP never served the purpose tha

[racket-users] A (long) question regarding parameters and scope

2018-08-01 Thread Carlos Lopez
Hello Racket friends, I was playing with the plot module (which is very nice, btw) and discovered that the parameter plot-decorations? is ignored when plotting to a new window. The file plot3d.rkt (plot\plot-gui-lib\plot\private\gui) is where plot-new-window? makes a distinction of the cases a

2018-08-01 Thread Alex Harsanyi
Parameters don't keep their values across threads, and since the plot library needs to re-draw the plot when it is rotated or zoomed, it saves parameters for later use in a different thread, where the drawing actually happpens. There is an explicit list of parameters that are saved and restore
