Possibly not the best use of my development time
I’m building and running a variety of test programs on an ipad emulator while I try to feel my way around using Apple’s Xcode CDE in tandem with a terminal window and levee (I’m sure it would be lovely to use whatever integrated editor Apple supplies with Xcode, but levee is a better editor) and, after a round of watching how one of the tinned demo programs worked, I brought up Safari and went to take a look at tsfr.
Isn’t it a lovely, if pointless, waste of time?
