Unexpected Help With Coding Projects

Fair warning, this is a post in two parts. First a project idea and second musings on the tools I used to create it.

I really do like to write code for fun. Nothing complicated (been there, done that, got the T-shirt - literally) but just little things to "scratch an itch" as they say.

Lately as I played Wordle I was wondering which letters appeared most in each place in the five letter words in my word list. A couple of nights ago, I wrote some code to find out. I had my code output a comma delimited file so I could use Excel to look at the results. That’s what the image to the side shows.

Now this sort of thing is highly dependent on the word list of course. But for my list, S is the most common letter in the first and fifth location. Not surprising as S is used to make plurals. Wordle doesn’t use plurals so I note that the second most common fifth letter is E with Y a close second.

The letter A is the most common second and third letter. The letter E is the most common fourth letter.

If I were ambitious, I could probably use this information to make a smarter Wordle solver. I’m not quite that ambitious though. I am toying with gathering some other statistics though.

I develop using Visual Studio – the full blown version. That means that Copilot jumps in to help. That’s not something I anticipated when I started but I confess that I found it surprisingly helpful. I did specifically ask Copilot to write one specific method – generate a string array of two character combinations – but it jumped in on its own with a couple of small bits of code. I was surprised at how well it anticipated what I wanted.

The implications for teaching programming are something to think about. On one hand it’s scary that AI tools can so easily write coding solutions to simple programming assignments. That turns our process of evaluating learning on its head a bit. At the same time, I am not ready to blindly trust AI generated code. I do not want students to blindly trust it either. So asking students to test generated code seems like a reasonable thing to assign. Yes, I suppose some students will ask AI to generate test cases but if we can’t trust AI to write the code in the first place we can’t trust the generated test cases.

We could ask students to explain the test and related tests. Could be quite a recursive rat hole.

We can also ask students to explain the generated code. We should probably ask them to do that either verbally or by writing manual in class so they can’t ask AI to do it for them.

What I keep coming back to in my own thinking is a focus on abstraction and top down design. Can we ask students to break the problem down to component parts and have them prompt the AI to implement various methods and code pieces. A focus on design rather than writing code. We could have students submit the design document and the various prompts that they use. Add to that some serious examination of testing and verification.

Students are going to have to work with artificial intelligence. They can’t let it do all the work for them because AI is not I enough yet. I don’t think it ever will be either.

User Interfaces and Microwaves and Artificial Intelligence

It seems like just about everything has a user interface these days. It is sometimes hard for me to question them. What sort of decisions go into their design? Microwaves are one such thing that I keep thinking about. My current microwave defaults to pushing a number button running that many minutes. That’s great when you want it to run in whole numbers of minutes. What about fractions of minutes?

For fractions of minutes there is a button that is pressed first to let the microwave know you want to enter the number of seconds. So far so good. It can get complicated though if you don’t have the default whole minutes option.

My previous microwave did not default to whole minutes. If you enter 100 is that one hundred seconds or 100% of a minute? i.e 60 seconds? How is the decision made on something like that? What is intuitive to the user? Actually, I don’t know what my current microwave would do if I asked to seconds and entered 100. I think it would do 100 seconds as 90 does run for a minute and a half. I should try it I suppose.

It’s a computer related question of course because there is a little microprocessor in there somewhere and someone has had to program answers to these questions. I wonder how artificial intelligence would make UI decisions about things like this. It largely depends on the instructions or prompts given to the AI. People are going to have to have some input there. Right?

Will AIs have access to research on things like that? Will they be able to design and run human factors research? Will they think research is necessary or even desirable or just assume they know what is best for us?
