# Learning Topic Log

## Python

- Get PEP8 working in VSCode as linter and add to execute on save. (These are conventions not syntactic enforcements, style)

- Is there a thing like prettier to enforce double quotes over single for instance?

- Research: How do I make sure I am using `conda` and not the default install in VSCode ? PyCharm makes it easy to select environment.

- Research: best practice for separating projects into `conda` environments like npm

- Read-up more on types: what does it mean for Python to be dynamically typed. What is type-hinting really?
  - Use provided pdfs and John's books

## Bash

- Best way to run a command in a script - is it to `echo` it?
- How to handle the return value of a command
  - If it returns multiple values, how to isolate and loop through them
- ~~What the weird variable symbols mean like errors and stuff~~
- ~~Read up properly about `find` and `read`~~
- `.list` file extension
- Error handling
- ~~Splitting strings~~

  - https://dane-bulat.medium.com/the-awk-programming-language-an-introduction-7035d343cd30
- Why do we have to do `"$var"` instead of `$var` or `${var}` at times

## SQL

- What is a _schema_ in MySQL/ SQL ?

- Do basic exercises from Amazon on aspects I am interested in to get a practical feel for it
- Elastic Beanstalk and how it differs from using multiple different services at once
- AWS Amplify
- Deploy my own website on AWS

## NodeJS

- Build examples of read stream and write stream

## Git

- What is rebasing?
- What is cherry-picking?
- GitFlow methodology in the context of releases, hotfixes etc
- How can you rollback without a hard-reset, i.e. how can you keep the future state (from the point of view of the rolled-back branch) accessible?
- Tagging (also in relation to Git flow)
- See if there is an advanced Git course on LinkedIn

## JavaScript

Look into these new features:

- Proxy object
