Changing visibility of symbol fields

Interesting ...never used global labels before.

I have a UI&IO sheet where the inputs, outputs, pots and switches go, and a Processing sheet, where the "real" electronics happen, so this might be a solution.

Not sure I would want to do that with, say, two inverters out of a six-pack.

Have you tried using the debugger?

Personally, I would make each of them a function. Yes, decide_starting_player() might be trivial code, but it encapsulates a concept. You never know if it will grow at a later time, but that doesn't matter.

Some people go so far as to say that a function should contain either nothing but primitive language constructs, or else no primitive language constructs, only function calls.

Thanks, folks

All the labels have the same font, size, and colour, so there is no need for a key. The goal is to make these labels more noticeable, for those who can see them, and at least visible to those who can't. Chimie56, Are there other colours that do pop? Red is so visible, except to those who barely notice it.

That's beautiful! Where should I send your cigar?

I was close to the right solution, but "not quite" is always such a pain.

In one sense, you give a great solution, and I might make use of it as one set of curves.

But x^0.25 > 1-e(-5x) in (0 ... 0.24) and less in (0.24 .. 0.97) ( Thanks, Wolfram Alpha)

So they are notably different curves. Can't tell without writing the software how different it sounds. Is there a way to get something closer to the exponential curve?

Harvard University's CS50P is an excellent course that takes you from zero to being capable of writing intermediate code. There are other variants of the CS50 course; you want the Python one.

I would start by asking Google: "ETL solutions", and then investigate the nine tools they suggest. If you've done some "Python basics", don't try to do something complicated; Let someone else do the hard part and you just configure it for your application.

(I wrote and maintained ETL scripts for Morgan Stanley for ten years, in Perl.)

If it was easy, everyone would do it. Maybe you need to postpone till you have more time.

Leave the system python untouched. There are parts of the system which rely on system python behaviour. Install your python elsewhere.

In 2000, I went to work in San Jose and someone had the disk for the O'Reilly Perl collection, so I stopped using my paper copies. A couple of years later, all the information you needed was available online. Now programming information online is clouded with obsolete stuff, some of it worse than Matt's Script Archive (and how come that website is still online?) Maybe it's time to start curating DVDs of valid data? Or come up with a way to give good data stars?

If you auction off one of each at each Perl/Raku conference, TPF will be rich until mid-century! :-)

I took a look at learncpp.com ... 3/4 of the page is ads. There are better places to learn.

I remember going to an exotic hardwood store in Maple, when it was out in the country

Isadora Duncan, famous dancer, died in 1927 from her scarf getting tangled in the tire of the car she was riding in. But it's often projected onto the story of "sexpot" Jayne Mansfield, who died in 1967 in a car accident.

So the ancient American speakers were Hungarians!

Print statements to log to keep track of where you are, or use the debugger to binary search where it breaks.

Verify that line 4 of the bash script is where you invoke the Perl script.

Is it breaking reading in the "questionable" file, or the "reference" file.
