# 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~~ - Awk - 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 - The `test` program (does it actually use the word 'test' or is this implicit?) and its use of `-z` and and `-e` flags ## Linux - `/dev/null` in greater depth ## SQL - What is a _schema_ in MySQL/ SQL ? - Proper definition of "migrating a database"? ## GraphQL - What is a transformer? ## AWS - Start reading more specifically about key services: Lambda, step functions, CloudFormation, Elasticache, CloudFront, CloudWatch - 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 - `Object.hasOwn()` - Top level `await` - `Error.Prototype.cause()` - Dynamic import - Temporal - `Promise.allSettled()`, `Promise.any()`
