Hacker News Stories and Comments
All the comments and stories posted to Hacker News that reference this video.⬐ lprovenWhat on Earth is the point of this? It seems like such a trivial exercise. No labels? Only Zone 1? No option to zoom out or pan around, which might have made for some interesting code and explanations thereof.⬐ flemhansNice. I wonder how it would look if the non-existing colors were drawn as dotted lines using two different colors.⬐ mellosoulsWhen I was a kid I created a pseudo-Draw command for Mode 7 (which I vaguely remember didn't allow graphics).This entailed (again from vague memory) working out roughly where the line should be plotted (which algorithm I later proudly discovered had a name - "Bresenham's line algorithm") and printing modified characters to generate the line. I think eventually you ran out of characters so it only worked for a few lines before odd effects started happening.
I can't fathom what motivated me to do this, it seems utterly pointless beyond childish nerd bragging rights, though I had done a project related to the modified character stuff so perhaps it was that.
Anyway, my rambling point is that computers then seemed so much fun for little hackers-to-be, so easy to get stuck into instantly even if the things you were doing had no greater goal than your own amusement.
Many years on and evaluating them in these heady days of raspberries (same heritage), python and its infinite libraries and I don't know what else (we are in another golden age I think) - the BBC computers are still as good as anything I have ever used in that regard.
