I’m just back from watching Mastering Claude Code in 30 Minutes , a talk by Boris Cherny, who, I learned, created Claude Code. I was struck by Boris’s reply to one question from the crowd: Hey, why did you build a CLI tool instead of an IDE? Yeah, it’s a good question. There are two reasons. We started this at Anthropic, where people use a broad range of IDEs. Some people use VS code. Other people use Zed, Xcode, Vim, or Emacs. And..

This article was originally published in 2018, yet its core insights into Go’s garbage collection model remain highly relevant for developers today. While some implementation details of Go’s runtime have evolved, the foundational concepts explored here—such as the semantics of the tri-color mark and sweep algorithm, Stop The World (STW) events, and GC trace interpretation—are still essential to understanding how Go manages memory. Whether y..

After going in deep in product, I found myself drawn to a different challenge: making other developers more productive. As one of my biggest mentors would always say: “Developer productivity is always ‘Multiplier work’, especially in places where you have a lot of developers. By saving a couple minutes from every developer, every day, you’ve saved years of human life waiting for stuff.” The project that really forged me was the Office migra..

Update 6/10: Based on a short conversation with an engineering lead at X, some of the devices used at X are claimed to be using HSMs. See more further below. Matthew Garrett has a nice post about Twitter (uh, X)’s new end-to-end encryption messaging protocol, which is now called XChat. The TL;DR of Matthew’s post … Continue reading A bit more on Twitter/X’s new encrypted messaging →

I build databases for a living, and as such, I spend a great deal of time working with file I/O. Since the database I build is cross-platform, I run into different I/O behavior on different operating systems all the time. One of the more annoying aspects for a database developer is handling file metadata changes between Windows and Linux (and POSIX in general). You can read more about the details in this excellent post by Dan Luu. On Wi....

Previously I had covered the worst program I had ever worked on (although that probably needs updating now) and the worst individual and the most incompetent individual I ever worked with. I thought it was time to lay out one of my own failures, of which resulted in me adopting trust by verify for a all future interactions… at least until I am more familiar with the individual. This was back when I was working on C#, SQL Server an..

I decided to write this post because something that seemed simple and easy, turned into a deep rabbit hole of UPS units, USB updates, serial cables, network cards, and other mess… Introduction It all starts when I decided to change the UPS that keeps the server/cabinet running. I had found an offer on Amazon for the same UPS as my actual one but the new model, which has the option to be monitored via apcupsd exporter , this is the model:..

Why Bell Labs Worked is a fascinating, evocative read. We live in a metrics obsessed culture that is obsessed with narrowly defined productivity. There’s too much focus on accountability and too little focus on creativity. The reason why we don’t have Bell Labs is because we’re unwilling to do what it takes to create Bell Labs — giving smart people radical freedom and autonomy. The freedom to waste time. The freedom to waste resources...

Federico Pereiro’s Being Fat is a Trap is, I think, a great piece of advice. Way more people than I wish who are close to me are struggling with eating disorders of all kinds, so I’m sensible about the topic. This sentence, in particular, rings true in an aching way: Judging people inside the fat trap just intensifies their misery and reduces the odds they can get out of it.

Since I got into programming, I’ve regularly seen operating-systems tutorials and implementation guides pass by. They always leave a lingering desire behind them, an echo of the well-known siren song: “when are you going to create your toy operating system?” Inevitably, time passes and the desire fades, till the next tutorial shows up and the cycle repeats. Today I’m breaking the cycle. I’m setting a challenge for myself, and I’m publishing..
