tictactoe

• What is tic tac toe?
• Build a data structure to represent the game board.
• Write a function that updates the board with somebody's chosen position. Don't worry about detecting if somebody has won.
• Write a function to detect that somebody has won.
• What should the UI look like? Use excalidraw to mock up the layout of the page
• Set up codesandbox.io with React and draw the board using the data structure we built earlier. Don't make it interactive, just draw the board.
• Add a feature so that clicking on the board fills the spot.
• Show a message when the game is over.

Algorithms notes

• Implement binary search in js without recursion
• implement quick sort in py and js
• implement merge sort in js

for queues, you dequeue from 0 and enqueue at -1

Support CORS. Allow the API to be accessed through webapps without having to setup a proxy server in between.

Add documentation! Sneaking around the API and looking at the the trip planner code is not optimal.

Build an API the right way. Provide API keys so you can throttle requests and make sure things aren't getting slow.

More frequent polling of the bus locations. Right now it takes 30-90 seconds for bus locations to update. This sucks for users.

When will the 803 info be added to the GTFS database?

Debugging reselect performance

Some steps I'm taking to debug bad performance with reselect.

My performance problems are coming from the fact that I am not using reselect properly. I wrote a bunch of selectors that use props but don't do anything to make sure they can be shared across multiple components.

The fix for this is: https://github.com/reactjs/reselect/blob/fec65b63b9a2ffa570348271138d20cf831e0185/README.md#sharing-selectors-with-props-across-multiple-components.

But before rewriting tons of code, I'd like to see which selectors are recomputed the most.
