[cctalk] Re: Computer Museum uses GreaseWeazle to help exonerate Maryland Man

I'm familiar with Scratch, my daughter used it in elementary. I had forgotten about it though - it seemed focused on the task of depicting and moving objects on a 2D area, not so much in general information processing (but still, yes it could be a starting point). One hallmark of a "good development environment" that someone once told me is that that development environment can be used to create itself. Like, by Borland Delphi 2, they used Delphi to create Delphi. Same on the Visual Studio development team - they compile and develop VS using VS. So, I wonder if Scratch can create itself? It's not a hard rule, just a casual observation on the "robustness" or maturity of a given development environment. There's always been a kind of "two tiers" of software developers - those who can create reusable routines (libraries) and those who can mold existing libraries to build applications. Obviously some can do both, but generally the latter get "stuck" if there isn't some existing function/routine in an API to do what they need to do -- like open a socket, start a thread, or query system time. The former tends to need to sink into OS and HW specifics. With this "blocked" code floating in VR -- the idea is then "behind the code" to show a virtualization of the resources needed by that code, to quickly get an idea of the hardware requirements (relative to how many resources it is using) and also linkages to other software, to get a feel for the overall complexity. These are important metric to see the versatility of re-using that code in other environments/platforms. And back on the stenography-keyboard like thing -- what about morphing keys? If a keyboard had actual screens on the keys, and the keys change (the actual symbol) based on the context of whatever you're doing. I know we have macros and reprogrammable keyboards, but morphing the actual symbol on the keys might be neat. Also, does any processor support a dynamic instruction set? I've wonder if some instruction-set optimizer might find improvements by indicating your program could be executed more efficiently if such-and-such instruction was available.
