Listen Or Speak — Mike Fisher
tl;dr: Mike, former CTO at Etsy, discusses how he navigates leadership styles - the under-importance of listening, the over-emphasis on speaking, and examples of how effective leaders leverage both. “While I still prefer a leadership style of listening before speaking, other than in emergency situations, the convergence of speaking and listening are complementary forces in leadership. The dynamic balance between the two crafts a leader who not only inspires but also empowers. Such leaders create environments where dialogue thrives, ideas flourish, and consensus is reached without compromising the vision or the drive needed for action.”

Strength Dictates Weakness — Andrew Bosworth
tl;dr: Andrew, the CTO at Meta, discusses how “your greatest strengths almost certainly dictate your greatest weaknesses... I have always considered communication a strength of mine. I enjoy speaking and writing, and do so often. I am forceful in championing my point of view. It took years to realize that I was “communicating” so much that I wasn’t listening. I was either drowning out my peers or waiting for my turn to speak.” Andrew discusses how this was a pivotal moment of growth for him. CareerAdvice |

The Self-Rendering Eval Shirt — Eric Simons
tl;dr: The free t-shirts companies give away to developers are everywhere and, with a few exceptions, most are pretty boring: usually just a logo on a t-shirt. In this post, see how StackBlitz’s co-founder broke this mold with a t-shirt design that incorporated the StackBlitz logo constructed with *actually valid* JavaScript code that is the source code of the image itself.

Let's Build The GPT Tokenizer — Andrej Karpathy
tl;dr: “In this lecture we build from scratch the Tokenizer used in the GPT series from OpenAI. In the process, we will see that a lot of weird behaviors and problems of LLMs actually trace back to tokenization. We'll go through a number of these issues, discuss why tokenization is at fault, and why someone out there ideally finds a way to delete this stage entirely.”
