How to Problem Solve - Funny Cats Edition

Problems solving is a skill, one which can be refine and improved in just about anyone...

For my example, I'll be using the simple situation of cleaning a litter box.

Step 1:  Analyze a problem statement, typically expressed as a word problem.

"How is a litter box cleaned?"

Step 2:  Express its essence, abstractly and with examples.

"Get everything I need, clean the poop out until it's gone, then add litter, and put everything away."

Step 3:  Formulate statements and comments in a precise language.

"Prepare for task"
get scooper tool, litter box, bag, litter. find litter box
“Completion detection loop logic”
if no poop detected, goto statement 5
“Remove unwanted objects”
scoop poop, place in bag,
“Scan for unwanted objects”
look for more poop, goto statement 2
“Add required material”
reinsert litter to replace the removed material
“Return to original state”
dispose trash, return litter. return to previous task

Step 4:  Evaluate and revise the activities in light of checks, tests and details.

Think of how your specific situation calls for changes in the overall algorithm.
Think of how you may need to break down certain statements into multiple specific statements, or add new ones entirely to satisfy the requirements.

Understanding Programming

I really like this guide to learning to program, because it doesn't teach you to code.

It's all about logic, which is what programming is really all about.

It's a read everyone ought to investigate.


Understanding the operation regions of Bipolar Transistors

Transistors have two main purposes in modern electronics, switches and amplifiers.

How the transistor's base controls the flow of electron from the collector to emitter is builds upon diode technology, and must be studied to fully understand the transistor.
