Young Reacts #95 – Erikson’s A (Mostly) Complete Guide to React Rendering Behavior

I watched a fascinating talk on GraphQL. Its premise is what made it fascinating; to convince people on the other side, we need to understand their reasoning to the point where we can make the argument more convincing than they can. Instead of talking about why we need to use GraphQL, Robert Zhu discusses the pitfalls of GraphQL at a GraphQL conference so that we understand the skeptics. Watching this talk made me reexamine how I promoted new ideas at work.

Blogged Answers: A (Mostly) Complete Guide to React Rendering Behavior – Mark Erikson

As I worked on building an interactive and performant table of thousands of items, I learned I still didn’t fully understand how React hooks behave. For example,

  • When I have multiple setState statements, will they force the component to rerender multiple times?

GitLab’s outbound recruiting model – Gitlab

GitLab has turned its recruiting model on its head. They explicitly state that “we do not accept inbound applications for our roles.” Looking back at my manager days, I realize all my best hires were from referrals and outbound sourcing. Maybe it’s not a bad approach if I can invest a significant amount of time recruiting.

Bond was the last straw: Regal and Cineworld will reportedly close all theaters in US and UK next week – The Verge

With the disappointing result from the highly expected movie “Tenet” and other blockbusters postponed until 2021, the second-largest US theater chain is also now shutting down its operations until 2021. Given the way things are going in the US, I wonder if any theaters will survive at all.
