How zustand works internally
import { useSyncExternalStore } from "react";
// For more on the useSyncExternalStore hook, see https://react.dev/reference/react/useSyncExternalStore
// The code is almost identical to the source code of zustand, without types and some features stripped out.
// Check the links to see the references in the source code.
// The links are referencing the v5 of the library. If you plan on reading the source code yourself v5 is the best way to start.
// The current v4 version contains lot of deprecated code and extra stuff that makes it hard to reason about if you're new to this.

How to install mysql2 gem on m1 Mac

Problem

Installing mysql2 gem errors on Apple silicon M1, M2 or M3 Mac running macOS Sonoma.

Solution

Make sure mysql-client, openssl and zstd are installed on Mac via Homebrew.

Replace mysql-client with whichever mysql package you are using

How to install different Ruby versions with chruby

Managing Ruby Versions with chruby

So I'm always forgetting how to do this! I guess I'm only ever updating Ruby versions every now and then.

Checking out which Ruby versions chruby has access to

$ chruby will display your installed rubies and show you the version you're currently using in your shell.

   ruby-2.1.2
   ruby-2.2.1
 ruby-2.3.1
#!/bin/bash
# Jenkins Configuraitons Directory
cd $JENKINS_HOME
# Add general configurations, job configurations, and user content
git add -- *.xml jobs/*/*.xml userContent/* ansible/*
# only add user configurations if they exist
if [ -d users ]; then
user_configs=`ls users/*/config.xml`

statement on event-stream compromise

Hey everyone - this is not just a one off thing, there are likely to be many other modules in your dependency trees that are now a burden to their authors. I didn't create this code for altruistic motivations, I created it for fun. I was learning, and learning is fun. I gave it away because it was easy to do so, and because sharing helps learning too. I think most of the small modules on npm were created for reasons like this. However, that was a long time ago. I've since moved on from this module and moved on from that thing too and in the process of moving on from that as well. I've written way better modules than this, the internet just hasn't fully caught up.

@broros

otherwise why would he hand over a popular package to a stranger?

If it's not fun anymore, you get literally nothing from maintaining a popular package.

One time, I was working as a dishwasher in a restu

npm publish a beta package

Steps to publish a npm package to beta that won't be available via latest and won't auto install on ncu updates etc

  1. Ensure any compile is run npm run dist etc
  2. Modify version in package.json to the following format (match with existing verion numbers etc) "version": "0.1.120-beta.1" where beta.x is the number of those betas
  3. Publish to npm npm publish --tag beta

There are two options for install:

  • Always install beta with npm install packagename@beta
  • Install specific version with npm install package@0.1.120-beta.1
