Thanks for the feedback. I do have in my presentation notes that the entire vocabulary fits on one page - I meant to emphasize that what I show is a sample, so I should mention the size of the "population".
When I'm talking about "compact", I was thinking of writing a Newton solver in one line but it wouldn't hurt to mention the small size of the interpreter + libraries as well. I estimate this as about 2.7MB for the interpreters and dlls plus about 22MB for the addons, as well as about 17.5MB for the system, tools, help, and icons directories for a total of 42.5MB - still svelte by modern standards: +/ 2723080 22323739 NB. bin/j.exe, jconsole, jnative, jee, j.dll, j.jar + addons 25046819 +/ 6926980 856946 9184784 573168 NB. j602/system, tools, help, bin/icons 17541878 +/ 25046819 17541878 42588697 I'll see if I can wedge in a few more elementary examples though I have less than 50 seconds per slide. Good catch with the missing negative sign - another cut-and-paste "droppo". I'll post an updated version in an hour or so.
