Getting Started With Kubernetes On A High Level

One of biggest barriers when trying to get started with Kubernetes is that there's so much content out there that it's kinda overwhelming - and that's totally normal! The intent of this document is to try and provide directed resources in a roadmap like fashion to understand and learn about the horizontals of Kubernetes - post which you can dive deep into any vertical while keeping the bigger picture in mind - that this document hopes to provide.

This is a set of resources for different topics that I found particularly helpful when getting started, and hopefully you do too! I've tried to list them out in order of consumption. If A comes before B under a subtopic, then it's probably that A has topics needed for B, or that A attempts to explain topics of B in a slightly simpler (not nescessarily better) manner than B.

Containers

Feel free to skip over if you're already familiar with containers and have some idea about what they are and why they exist.

Disclaimer

This is not a Documentation format. This is a very close transcription of Academind's video: "TypeScript Course for Beginners 2021 - Learn TypeScript from Scratch!", which was a part of my learning process. I highly recommend watching the entire 3 hours course available on Academind's YouTube channel.

This is not a 1:1 transcription (roughly 90:100) - do not rely on these notes as some parts of the video were skipped and it contains some self-interpreted content.

GitHub anchors might not work, sadly ¯_(ツ)_/¯

How to recover a dropped stash in Git?

1. Find the stash commits

git log --graph --oneline --decorate ( git fsck --no-reflog | awk '/dangling commit/ {print $3}' )

This will show you all the commits at the tips of your commit graph which are no longer referenced from any branch or tag – every lost commit, including every stash commit you’ve ever created, will be somewhere in that graph.

Well, this fun moment when you're trying to follow the answer from stackoverflow =)

Принципы разработки Амплифера

Тут перечислены не законы, последние слово всегда за здравым смыслом. Тут перечислены лишь направление, куда надо стремиться. Принципы, которые должны помочь, когда не знаешь, что выбрать.

Пользователь. Если что-то сильно мешает UX или есть критическая ошибка, то в первую очередь мы спасаем пользователей. Для этого иногда надо взять ответственность на себя, переубедить толпу, написать плохой код.

Node postmortem debugging (OSX)

1. Taking core dump

To get core dump of running node process:

Take PID of that process:
```
pgrep -lf node
```

	import { Application } from "https://deno.land/x/oak/mod.ts";
	import { applyGraphQL, gql } from "https://deno.land/x/oak_graphql/mod.ts";

	const app = new Application();

	const types = gql`
	type Dino {
	name: String
	image: String
	}

	export const ws = webSocket<WebsocketMessage>(`wss://${location.hostname}:${location.protocol === 'https:' ? 443 : 80}/ws/`);

	export const wsObserver = ws
	.pipe(
	retryWhen(errors =>
	errors.pipe(
	delay(1000)
	)
	)
	);
