Using shared-structs with Workers <3

This showcases how you can use shared-structs over an SharedArrayBuffer, to share complex data structures between worker_threads in Node.js

The main.js example starts a worker and passes a shared struct to it.

The worker will periodically update the struct with an incrementing tick and a random number

ESM modules in node: npm edition

The proposal you’re about to read is not just a proposal. We have a working implementation of almost everything we discussed here. We encourage you to checkout and build our branch: our fork, with the relevant branch selected. Building and using the implementation will give you a better understanding of what using it as a developer is like.

Our implementation ended up differing from the proposal on some minor points. As our last action item before making a PR, we’re writing documentation on what we did. While I loathe pointing to tests in lieu of documentation, they will be helpful until we complete writing docs: the unit tests.

This repo also contains a bundled version of npm that has a new command, asset. You can read the documentation for and goals of that comma

Откат ошибочной команды `git push --force`

Иногда при работе с несколькими удалёнными репозиториями в git, может произойти страшное: git push --force в не тот remote и/или не в ту ветку.

Такое может случиться, например, если вы используете [Deis], в котором деплой запускается при git push нужного коммита в сборщик, когда при отладке деплоя после очередного git commit --amend по запарке вместо git push deis master --force делается просто git push --force. Упс.

Как результат, последние коммиты коллег безвозвратно потеряны, и вы чувствуете неотвратимость их ярости…

Но это git, а значит всё можно починить!

What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

	// This is an advanced example! It is not typically required for application code.
	// If you are using a library like Redux or MobX, use the container component provided by that library.
	// If you are authoring such a library, use the technique shown below.

	// This example shows how to safely update subscriptions in response to props changes.
	// In this case, it is important to wait until `componentDidUpdate` before removing a subscription.
	// In the event that a render is cancelled before being committed, this will prevent us from unsubscribing prematurely.

	// We also need to be careful about how we handle events that are dispatched in between
	// `getDerivedStateFromProps` and `componentDidUpdate` so that we don't put stale values into the `state`.
