I have installed the new beta on my MacBook and on a Ubuntu server. No
particular problems, but some fiddling around was required to get jQt working
on the Mac. I only use ssh access to the Linux server, so that removes the
fiddling.
I decided to run my favorite benchmark (inverting a matrix).

Not surprising, but jconsole, and jqt work just fine in OS X 10.13 (High

Also reporting good news that J701 runs fine in iOS 11.
Looking forward to seeing/doing some benchmarks on the new iPhones. Love the *2

I was working with a friend on some curve fitting things and we were

Thank you Brian, using 'type symbol' does avoid the length error, e.g.

but puts a tiny red numeral 2 at (approximately) 2.2,3 on the canvas,

Have you tried your experiments without the intermediate pd show?
The example I suggested does not have the intermediate pd show, for example.

Very nice. I assumed that the fix was pretty minor. But I agree with your first
take on this, that simplicity is the real goal - putting data requirements on
the J side gives a lot more "flexibility" for entry of data.
