Creating A Culture Of Listening

— Kim Scott


tl;dr: Kim contrasts (1) Quiet listening: listening with periods of silence to encourage others to talk with (1) Loud listening: saying things to prompt a reaction from others and have them challenge you. Whether through quiet or loud listening, leaders must create an environment where everyone's ideas are heard, debated, and tested. Embrace diverse perspectives, empower employees to contribute, and establish systems for generating ideas and addressing concerns.

Leadership Management Productivity


“I’m opposed to setting aside time for refactoring. In my view refactoring is not an activity you set aside time to do. Refactoring is something you do all the time in little bursts.”  


— Martin Folwer


How To Evaluate Dependencies

— Phil Booth


tl;dr: “One of my stock interview questions goes: "When picking between dependencies to use in production, what factors contribute to your decision?" I'm surprised by how often I receive an answer along the lines of "Github stars" and not much else. I happen to think Github stars is a terrible metric for selecting production code, so this post sets out my idea of a healthier framework to evaluate dependencies.”

Investigating The Impact Of HTTP3 On Network Latency For Search


tl;dr: The Dropbox engineering team discusses experiments conducted to improve search latency: “at the beginning of our investigation into network latency, we only knew the hypothetical benefits of HTTP3.

Is 20M Of Rows Still A Valid Soft Limit Of MySQL Table In 2023?

— Yisheng Gong


tl;dr: “There’s rumor around the internet that we should avoid having > 20M rows in a single MySQL table. Otherwise, the table’s performance will be downgraded, you will find SQL query much slower than usual when it’s above the soft limit. These judgements were made on HDD many years ago. I’m wondering if it’s still true for MySQL on SSD in 2023, and if true, why is that?”

Donald Knuth On ChatGPT

— Donald Knuth


tl;dr: “Since one of today's popular recreations is to play with ChatGPT, I decided to try my own little experiment, as part of a correspondence with Stephen Wolfram.The results were sufficiently interesting that I passed them onto a few friends the next day, and I've also been mentioning them in conversation when the topic comes up. So I was asked to post the story online.”
