### Re: 2D graphics/turtle lib suitable for kids?

I'm all for simplicity, and I'll take it in whatever form it comes in, low level or high. Resolution independence shouldn't be that hard: turn +width+ and +height+ to *width* and *height*, set them to your resolution and rerun the program. That is how postscript does it, it's just a variant of Fort...

### Re: 2D graphics/turtle lib suitable for kids?

You're not teaching trigonometry, but basic geometry. You're still working from coordinates, just abstract ones. fd 1 (forward one, in a hypothetical dialect) could be one pixel (it was in Apple Logo) but it could also be an arbitrary distance, with 1.235 as a possibility, as well. Advocating direc...

### Re: 2D graphics/turtle lib suitable for kids?

Different strokes for different folks, but I would have found that tedious and painful. LOGO is beautiful, because once you write a few routines you can use those to draw stick figures and other simple objects, and if you have something more complete at your disposal (like SDL gives) you can grow f...

### Re: 2D graphics/turtle lib suitable for kids?

I think Duke's idea is a good one (if you have the time). I discovered programming through Basic, because I could put it into mode 13h and draw pixels. I think pixel plotting is probably an easier starting point than rotation, recursion and line drawing. Were it me, I'd probably use SDL to create a...

BAH! Just use a triangle!
It was good enough for when I was learning how to work Apple Logo on my //c with the tiny phosphorescent green-screen

### Re: ECL: Compile Lisp to C

I wrote a bash script, which creates a backup of the .c/.h files after being written to them. Now I have another question: Did anyone manage to compile ECL on Windows using MSVC++? I get the error "msvcrt.lib" not found (by nmake), although ...\VC\lib is in PATH. It's designed to work with GCC iirc...

I didn't ever do touch-typing exercises, not intentionally anyway.
In fact, seeing as I'm dysgraphic, those touch-typing exercises they had me doing were systematic in a way that left me spelling things weirdly until I got off qwerty.
