Ch.1

data intensive apps are built from building blocks:

• db - store data to find it again later
• caches - remember res of expensive calculation
• search indexes - allow users to search via keyword or other ways
• stream processing send msg to another process to be handled async
• batch processing - periodically crunch a bunch of accumulated data.

questions for designing systems

• how do you make sure data remains correct and complete, even when things go wrong internally?

State

'clear the clutter in our heads and our minds'

Invert

• we're evolutionarily wired for 'easy', embrace it
• Carl Jacobi, Mathematician - "one must invert, always invert" ^ transform a problem into a different representation to make it easier to work with

just asking, "what if this could be easy?" is a simple way to reset your thinking

choosing an indirect approach - for a really difficult task (as opposed to hitting it head-on)..how do you do this in practice? Consider strategy before doing aka "how should I approach this for ease?"

Combined guide from reading https://pne.people.si.umich.edu/PDF/howtoread.pdf and How To Read a Book by Mortimer Adler.

1. Decide how much time you'll spend

2. Have a purpose and a strategy

why you're gonna read it and how you're gonna do it

• Who is the author?
• What are the book’s arguments?
• What is the evidence that supports these?

Notes taken from reading How To Read a Book by Mortimer Adler.

"Knowledge is not as much a prerequisite to understanding as is commonly supposed. We don't have to know everything about something in order to understand it; too many facts are often as much of an obstacle to understanding as too few. There is a sense in which we moderns are inundated with facts to the detriment of our understanding." - p.4

"Reading is a complex activity that consists of several acts, all of which must be performed to be 'good reading'."

Levels of Reading

1. Elementary - "what does the sentence say?"

Notes from Putting An Age-Old Battle To Rest

Traditional rules of simple code design:

1. pass its tests
2. minimalizes duplication
3. reveals its intent
4. reduces the number of classes/modules/packages

^This is put in order of importance. Now some have argued over the order of 2 & 3, because when you're doing one you're doing the other...these 2 rules inform each other in a rapid feedback cycle.

React Performance

Notes From Steve Kinney's "React Performance" Frontend Masters Course

General

re: optimizations: "Start with a problem first, then solve it. dont go looking for problems."

"measure first before you optimize for performance. And then measure again."

Dictionaries

TL;DR: An object which stores objects/arrays by key

Sometimes we need to represent a type for dictionaries, where values of a consistent type are retrievable by keys.
