In this month's Newsletter Keynote, we look at three companies that had a gold rush month.

The year started off with a riot in US capitol building which then turned every social media company against President Donald Trump. While giants like Facebook and Twitter blocked the President everywhere, a conservative free speech outlet Parler started gaining followers by second. Parler started stuttering as the loads increased and later altogether as AWS banned them from their servers. But here's a tech lesson from Parler debacle.

Whatsapp was all set to update it's terms and services starting next month and share some user information with their parent company Facebook. But there was widespread outrage regarding the policy to the point that WhatsApp had to claim a misinformation campaign later. People rushed to competing platforms like Signal and Telegram; Signal in particular gaining about 40 million users.

The joy was short-lived as Signal went down for long time and most people went back to WhatsApp following full page ads promising privacy from Facebook. How useful is a chat app if some of your friends are not on it?

The third company of the month is GameStop. They are a video game retailer in US who were kinda struggling because of the pandemic, blowing off some Steam. Some very large hedge funds were shorting the stocks for GameStop (well, including AMC theatres, Bed Bath and Beyond and others) and betting on it to fail. At some point, they went completely overboard as to have borrowed 130% of the stock.

This is when a subreddit that gambles on stock market called r/wallstreetbets caught a whiff of the money going round. The subreddit in a collective effort (raid!) pushed up prices of the stock and suffice to say, it skyrocketed.

Short after hedge funds starting complaining that the free market was too free, Robinhood the popular stock trading app stopped trading $GME and $AMC making everyone involved angry.

Tech Companies caught in this gold rush:

• Reddit: The subreddit had to be taken private due to sudden influx of users.
• Discord: The subreddit moved to it's own discord channel which had to banned as it got difficult to moderate. The channel is now back up as Discord is personally assisting their team.
• Twitch: That AOC stream
• Robinhood: Went up the ladder and fell as fast.

Releases

• Chrome 88 - Brings support for a much awaited property on the Web - aspect-ratio. No more padding-bottom tricks. (As always, check out browser compatibility). This update also defaults links with target=_blank to rel=noopener to prevent tabnabbing. It might be too quick to switch the error off on eslint, but it's safer now.
• Houdini Worklets - CSS Houdini allows you to create worklets - Tiny functions to extend CSS (Here's an explainer if you haven't heard it before). This page contains examples that you can use on modern browsers right now.
• Firefox for Apple Silicon - Apple might have mentioned it's a day task to port software to new Silicon. Firefox has published their case study of porting a browser.
• Snowpack 3 - Snowpack is a super fast web development environment and in v3 it ships with in build bundling, preloading, minification and more (in production mode of course). They have been on the rise in last few months - other alternatives are vite, wmr.
• WCAG 3 - First Public Draft. It's supposed to be easier to read, let me know if you did that.

Tutorials

• Performance Checklist 2021 - Smashing Magazine - Always amazing checklist for web performance from SmashingMag. Check out the Low hanging fruits section for some easy wins. They have also put out a long detailed case study of improving performance their own site
• Apollo Odyssey - Learning Platform - If you want to learn GraphQL with Apollo™️, hop onto their new learning platform complete with space puns. Netlify released JamStack Explorers last month, so it seems like Space is the theme so far.
• styled-components best practices - As I reiterate every chance I get, styled-components happens to be my favourite styling library. This best practices blog from Josh is an absolute treasure chest.
• TailwindCSS isn't for me - Tailwind is the new cool, but it might not be everyone. The article and comments contain some interesting distinctions and discussions. I hold that the popularity of Tailwind is not about CSS at all, it's about how it made developers feel like they didn't need designers (that was how bootstrap worked too). But in case you are a fan, here is a Tailwind romance novel.

In the Spotlight 🔦

Let's look at state management in React.

I have maintained my apprehension against using Redux because of my experiences of using it so far. One of my favourite instances are from starting out as a contractor on a project my first ticket was that all dropdowns on the page were being triggered simultaneously. A developer had put the state for dropdown in Redux not anticipating that there could ever be two dropdowns on the same page!

I can currently live with no third party libraries, just React Context, but then that's not state management, it's just global state. As Mark Erickson eloquently puts it:

Context is a form of Dependency Injection. It is a transport mechanism - it doesn't "manage" anything. Any "state management" is done by you and your own code, typically via useState/useReducer.

Link to his blog post explaining differences in detail.

There are a large number of solutions for state management that are currently available for React. Here is how they stack up:

Redux or comparable solutions pass only the store object to the components meaning that all components in the tree do not have to rerender if one value in the store changes. But this is not the case with Context. But this is changing, once this experiment goes through, useSelectedContext will enable to users to select when they want components to rerender.

Based on #20890 This is not a final API. It's meant for internal experimentation only. If we land this feature in our stable release channel, it will likely differ from the version presented here. ...
