Build a Deep Learning Library
Instead of just learning how to use a deep learning library, we are going to learn how to create one.

LLMs could be, but shouldn't be compilers
I’ve been going round and round in my mind about a particular discussion around LLMs: are they really similar to compilers? Are we headed toward a world where people don’t look at the underlying code for their programs?

Something Big Is Happening
A personal note for the non-tech people in my life on what AI is starting to change — why it's moving faster than you think, and what to do about it.

For AI leaders Doom is a form of hype
Why AI doom rhetoric from Anthropic, OpenAI and other tech leaders functions as hype, regulatory strategy, and a distraction from present harms.

The current balance of power in open models
The expanded form of a testimony I prepared for Congress.

DeepSeek-v4.1 Flash: Pushing the Limits of KV Cache Compression
A deep dive into the DeepSeek-V4.1 Flash technical report: CED, CSA2, HSI, Single-Pass mHC, Engram and FP4 KV Cache — how the KV cache was compressed to just 890 bytes per token.

Stop using natural language interfaces
Natural language is a wonderful interface, but just because we suddenly can doesn't mean we always should.

I turned Markdown into a protocol for generative UI
An AI assistant that builds reactive UIs mid-conversation — forms, streaming data, callbacks — using markdown code fences and a mount() UI primitive.

If AI coding is lowering your code quality, you're not managing quality right
One common take on the coding agents that I see goes something like this: “Sure, AI helps you output more code, but won’t the quality suffer?”

AI is destroying my CS degree
I am a computer science student. I got a scholarship to study computer science and AI last year and I love it! It's something that I wanted to do since I was...

Expertise in the age of AI
Junior engineers are expensive, both in salary and seniors engineers’ time. This cost was partially recouped through code contributions, but today, it’s more effective to directly maximize the output of your senior engineers. The hiring market reflects this trend: senior engineers have an easy time finding jobs, while…

After the AI Crash
Everything I read about the AI industry leads me to think there will be an AI crash. Consider the following: Unsustainable Capital Expenses. It’s hard to imagine there can ever be enough revenue to…

AI didn't simplify software engineering: It just made bad engineering easier
AI tools lower the barrier to producing code, not to building reliable systems. The hard part — maintaining alignment between specifications, tests, and implementation — has not gone away. Expertise still matters.

AI Is Breaking This Thing We Call Trust
AI-generated work can look finished without being understood. That uncertainty erodes trust, slows reviews, and leaves colleagues doing the missing work.

What happens inside an LLM when it tries to calculate with nothing but matrices.

When AI Costs More Than the Engineer
Anthropic spends 2.3x payroll on compute. Top software firms spend 0.4x. Three scenarios for where the rest of the market lands by 2029.

Will I ever own a zettaflop?
As the eleventh hour dawns all the pieces start to fall into place. I lived my life knowing this would happen, yet when it is I may be just as unprepared as anyone else. As any self driving car maker knows, predicting doesn’t mean you can act.

Local Indexing to reduce tool calling and token usage
Pensieve for developers: a local MCP server that gives Claude Code, Codex and Cursor your context. A thread for every piece of work. Free and open source, for Mac.

Claude Duet is the first personal-assistant-type harness that feels useful
Look, I really didn’t want to like Duet. I don’t want to be an Anthropic fanboy and it annoys me when they do things better than the competition. But they have done it again.
