Strategy for writing a logic program
I have had a hard time learning logic programming thus far, and my request for outside resources on this site was met with some opprobrium, so perhaps this question better addresses both my needs and the requirements of this community:
Is saying “if ( $a != null && $a == 5)” the same as “if ($a == 5)”
First off, sorry if this is answered somewhere else. I did a brief search, but wasn’t sure how to ask in search terms.
AND is better or using Internal “IF” [duplicate]
This question already has answers here: Is it bad practice to use short-circuit evaluation instead of an if clause? [duplicate] (7 answers) Closed 9 years ago. In a situation like this:” if ((metadata != null) && (metadata.TypeEnum != VariantInfoMetadata.CellTypeEnum.Status)) do you recommend to keep the code as it is above? Or is it better to […]
How would I combine ‘Command’ and ‘Composite’ to simulate a time delay?
As a learning exercise (I am not in school – just an old guy trying to learn something new), I am trying to write a logic gate simulation that incorporates propagation delay. The user should also be able to group gates together to create higher-level objects.
Given a situation, and some conditions, verify is that situation is possible
Well it’s a problem me and my friend had thought of, and well, haven’t come up with anything to solve the following problem(I’ll try to phrase it in the best way I can):

Calculating WPM given a variable stream of input
I’m creating an application that sits in the background and records all key presses (currently this is done and working; an event is fired every keydown/keyup). I want to offer a feature for the user that will show them their WPM over the entire session the program has been running for. This would be easy if I added a “Start” and “End” button to activate a timer, but I need to detect only when the user is typing continuously – ignoring all one-time keyboard shortcuts and breaks the user takes from typing.

Multivariable decisions
I am running into a situation where my program can have different outcomes depending on the state of some variables. 4 variables are involved and they can all have different ( 3 to 4 different states). All the possible combinations are leading me to about 48 different cases which would be resolved using a 4 level deep nested if/else structure. So, I have a couple of questions,
