Q: functional vs state-based

Saw Thinkar Nay HtooAs mentioned in Lambda Calculus - Computerphile, Alonzo Church's method is functional where a function as a blackbox, takes an input, processes, and produces an output, and Turing machines have internal state. First, I would like to know what does it exactly mean by functional and sta...

The down side of having a HNQ.
The current uptime on my Mac is 28+ days. I used to have a SUN that had over a year of uptime. I do normally restart the mac about once a month, though. But it normally takes that long for flakiness to appear.

If I wanted to add some thoughts to the touch typing question would you suggest I edit the question or my answer? I'd like to distinguish three things:
Typing with 9 fingers instead of three
Typing while looking at the hands or elsewhere (screen or notes)
Hunt-peck vs knowing the keyboard even for 3 finger typists.
--- I don't think that experienced 3 finger typists actually hunt and peck. They know by "feel" where the next key is.
I think the answers are confusing these things.
@thesecretmaster ^^^. Any advice?

Hello
I think clarifying that there are three circumstances which may occur would be helpful in the question (and possibly adding a plee for answers to be sourced), but your opinion on that should remain in your answer.
 
Buffy
Buffy
I don't think my answer would change for any of the three things. I would just add a note that there are three different things being merged.
Question then?
Let me try. Roll it back if you think it out of bounds.

How to grade my quizzes quickly?

You know about the "throw them down the stairs" method I assume.

They're not papers! They're all the same length, unfortunately.

Some land upright, some face down.
For a directory of work. Open a directory of papers. Close your eyes and click somewhere. Start at A for first paper chosen and work your way down.
Or let your kid point. Even better.
Except for the applesauce on your screen.

@BenI.Just make your exams follow the model set by Harvard College, Fall 2007, Computer Science 50: Introduction to Computer Science I, Quiz 1. Of course there is some work involved for the instructor. You have to explicitly instruct the students to "Read the entire quiz before doing anything else."
Or, depending on the value of your time, you could hire a TA.

It is possible, though difficult and time consuming, to make really good multiple choice quizzes that require work and not memory to get right. They can then be auto graded. But such questions also require work to validate since some are negatively correlated with overall knowledge and success.

Q: Requisites, pre- and post

Scott RoweSomeone kicked the anthill with the question about touch-typing, which raised the issue of prerequisites, which brings up the concept of a curriculum, which invokes the area of what in the world are we trying to accomplish anyway? The program of study that I used to teach had a very definite goa...

The explanation of the paper you cite certainly seems to say that touch typing is less important for a programmer, since most compose as they type.

And the alternative to looking at your hands is likely looking at the screen, not notes on the side, as secretaries do.
Font works fine.
Which font family is that?

Secretaries are some of the ones that need touch-typing skills

Yes, of course. But there are few secretaries anymore. People mostly type their own stuff I think (other than Lawyers).

@Buffy It's unicode, but that block is one of the better supported blocks.
Dictations still are common in upper levels of management and executive suites.
The only time that looking at the keyboard, or the screen, is "slower" is when you actually do have to look at notes or other "source" material.
I can touch type QWERTY and Dvorak at secretarial speeds. I still observer my fingers when coding. And usually when just composing other thoughts as well.
My "screen" time for the eyes is usually limited to when I'm in chat.

Here I have to watch the screen since the autocorrect sometimes gets it wrong. Same on my iPhone.
 
Gypsy Spellweaver

On the phone, when I must use it, the auto- correct/suggest sometimes comes in handy, and sometimes is not so handy. On the PC I have no such feature enabled (except for what Google does in the search).
I also don't use auto complete (hint/suggest/etc) in my code editing.
I do believe that muscle memory is a good part of the ability to touch-type. I watched a news story about some girl winning the spelling bee. I couldn't figure out what she was doing with her hands at first.
Then I finally realized she was "typing" the word, and reciting the letters her fingers would have pressed if she'd had a keyboard.

@GypsySpellweaver KOOL. In the extreme.
I've been pressing people pretty hard, I guess, on their lack of logic in their posts. I'm surprised no one has yet got on a down-voting binge for my other posts.
One user really wants to have the last word in comment streams. If he ended with something at least sensible, I could let it go, but there has been a lot of nonsense stated here as "simple fact". Tablets from Mt Sinai.
 
Gypsy Spellweaver
Gypsy Spellweaver
Your are referring to the tablets that became dust a few centuries back, yes?

Something like that, yes.
