That's very cool, Dan. Thanks for the example. (Although, shouldn't -4^2
+ 4^2 = 32, not 31?)
If/when you do the 'further challenges' section, could you post the result
here? It looks like it would be useful.

When you use `system` or `process`, the immediate new process runs a
shell. The shell process then starts another one to run the command
that you give it.
I recommend using `process*` to avoid the shell process and to avoid
encoding issues when passing arguments:

I'm having trouble with two interacting processes and am hoping someone can
point out whatever it is that I'm missing.
Process A starts process B and interacts with it but conditionally needs to
kill it. But using the procedure of one argument returned (as the fifth
element of a list) by pro
Maybe someone should verbalize what many of us know: DrRacket is useful,
and pretty neat.
I'm a long-time Emacs person, but DrRacket has some conveniences and
killer features that keep me coming back.

That makes sense. Thank you, Rickard.

It looks like it's not a question of running DrRacket for a while, but
of having multiple tabs in DrRacket. And, more specifically, it's not
about DrRacket, but about showing a window containing a `tab-panel%`
instance that uses the 'no-border style on OS X.
For example, start DrRacket with your p

I should have been more positive. It could be and is on the path to
improving, but I think i
mode-lambda is intended for this kind of work load. Try taking the demo,
going to the "rand" workload (line 140) and change in the in-range for W to
something like (* 10 W) (which would be 2.5k) and evaluating the
