I'm Boris and I created Claude Code. Lots of people have asked how I use Claude Code, so I wanted to show off my setup a bit.
My setup might be surprisingly vanilla! Claude Code works great out of the box, so I personally don't customize it much. There is no one correct way to

Update: This post has now become a book! Check out LLM-book.com which contains (Chapter 3) an updated and expanded version of this post speaking about the latest Transformer models and how they've evolved in the seven years since the original Transformer (like Multi-Query Attention and RoPE Positional embeddings).
In the previous post, we looked at Attention – a ubiquitous method in modern deep learning models. Attention is a concept that helped improve the performance of neural machine translation applications. In this post, we will look at The Transformer – a model that uses attention to boost the speed with which these models can be trained. The Transformer outperforms the Google Neural Machine Translation model in specific tasks. The biggest benefit, however, comes from how The Transformer lends itself to parallelization. It is in fact Google Cloud’s recommendation to use The Transformer as a reference model to use their Cloud TPU offering. So let’s try to break the model apart and look at how it functions.
The Transformer was proposed in the paper Attention is All You Need. A TensorFlow implementation of it is available as a part of the Tensor2Tensor package. Harvard’s NLP group created a guide annotating the paper with PyTorch implementation. In this post, we will attempt to oversimplify things a bit and introduce the concepts one by one to hopefully make it easier to understand to people without in-depth knowledge of the subject matter.
2025 Update: We’ve built a free short course that brings the contents of this post up-to-date with animations:
A High-Level Look
Let’s begin by looking at the model as a single black box. In a machine translation application, it would take a sentence in one language, and output its translation in another.
CTOs Reveal How AI Changed Software Developer Hiring in 2025
We asked 12 CTOs and CEOs what skill they now prioritize when hiring developers because of AI. Their answers validate what experienced developers suspected all along.
As we approach the 10 year anniversary of the 1.0 release of Kubernetes, let's take stock of the successes and failures of the project in the wild. Also what would be on a wish list for a Kubernetes 2.0 release.
Real-world engineering challenges: building Cursor
Cursor has grown 100x in load in just a year, sees 1M+ QPS for its data layer, and serves billions of code completions, daily. A deepdive into how it’s built with cofounder, Sualeh Asif
At the PGConf.dev 2025 Global Developer Conference, Bohan Zhang from OpenAI shared OpenAI’s best practices with PostgreSQL, offering a glimpse into the database usage of one of the most prominen
Today’s my last day at Carta, where I got the chance to serve as their CTO
for the past two years. I’ve learned so much working there, and I wanted
to end my chapter there by collecting my thoughts on what I learned.
(I am heading somewhere, and will share news in a week or two after
firming up the communication plan with my new team there.)
The most important things I learned at Carta were:
We might be seeing the end of remote interviews as we know them, and a return of in-person interviews, trial weeks and longer trial periods. Could hiring be returning to pre-pandemic norms?
Interview processes are changing in a tech market that’s both cooling AND heating up at the same time. A deepdive with Hello Interview founders, Evan King and Stefan Mai
