Top 3: system design of 20 big companies, how to measure React application performance and inflation

Hello my friends.

Here's what I picked this week, enjoy!

​
​1. System Design And Recommendation Algorithm Of 20 Big Companies​

TL;DR: A breakdown of the architecture of the recommendation algorithms of 20 major companies such as Google, YouTube, Netflix, Spotify, and others.

Who also, like me, likes to study architectures of complex systems, don't fall down the rabbit hole of tons of links in the article. It's only Monday.

​
2. Engineering Levels at Honeycomb: Avoiding the Scope Trap​

TL;DR: An alternative way to evaluate engineering levels.

There are seven levels of engineering in Honeycomb: H1 Intern, H2 Entry, H3 Engineer, H4 Engineer, H5 Senior, H6 Staff and H7 Principle.

And they evaluate the level by two criteria:

1. Scope – scale of tasks performed (tasks → features → projects → products → company)
2. Ownership – level of responsibility (execution → process → solution discovery → problem discovery)

As a "high-level way of evaluating" it looks interesting.

3. Get Fast, Stay Fast: How To Monitor React Render Performance​

TL;DR: How to measure React application performance.

10-K Diver @10kdiver 1/ Get a cup of coffee. Many of us are grappling with high inflation. We are worried about how inflation is going to impact our portfolios, and our costs of living.

That's all for this week, take care and have a great one!
