The web runs on tolerance
If you’ve ever tried to write a computer program, you’ll know the dread of a syntax error. An errant space and your code won’t compile. Miss a semi-colon and the world collapses. Don’t close your brackets and watch how the computer recoils in distress. The modern web isn’t like that. You can make your HTML […]
Transparent Leadership Beats Servant Leadership
tl:dr: Parenting and leadership is similar. Teach a man to fish, etc. I spent a couple of years managing a team, and I entered that role – like many – without knowing anything about how to do it. I tried to figure out how to be a good manager, and doing so I ended up […]
Functional Quadtrees
A Quadtree is a tree data structure, which is useful for giving more focus/detail to certain regions of your data, while saving resources elsewhere. I could only find a couple tutorials/guides and both were imperative, so I figured it’d be fun to do a functional version in Clojure which runs in the browser. A demo […]
Uninitialized garbage on ia64 can be deadly (2004)
On Friday, we talked about some of the bad things that can happen if you call a function with the wrong signature. The ia64 introduces yet another possible bad consequence of a mismatched function signature which you may have thought was harmless. The CreateThread function accepts a LPTHREAD_START_ROUTINE, which has the function signature DWORD CALLBACK […]
I ignore the spotlight as a staff engineer
Lately I’ve been reading Sean Goedecke’s essays on being a Staff+ engineer. His work (particularly Software engineering under the spotlight and It’s Not Your Codebase) is razor-sharp and feels painfully familiar to anyone in Big Tech. On paper, I fit the mold he describes: I’m a Senior Staff engineer at Google. Yet, reading his work […]

The issue is rated CVSS 10.0 and can allow remote code execution when processing attacker-controlled requests in unpatched environments. This vulnerability originates in the upstream React implementation (CVE-2025-55182). This advisory (CVE-2025-66478) tracks the downstream impact on Next.js applications using the App Router. […]
Building optimistic UI in Rails (and learn custom elements)
Custom elements are one of those web platform features that sound complicated but turn out to be surprisingly simple. If you have used Hotwire in Rails, you have already used them. Both and are custom elements. They are just HTML tags with JavaScript behavior attached. This article walks through what custom elements are, how they […]
Programming peaked
by Samir Talwar Tuesday, 25 November 2025 at 09:00 CET I remember my first job vividly. It helps, of course, that I still consider many of the people I worked with friends, and I know some of them even still read this blog. (Hi!) I also think it might have been the beginning of the […]
It’s time to free JavaScript
You have long ago abandoned the JavaScript trademark, and it is causing widespread, unwarranted confusion and disruption. JavaScript is the world’s most popular programming language, powering websites everywhere. Yet, few of the millions who program in it realize that JavaScript is a trademark you, Oracle, control. The disconnect is glaring: JavaScript has become a general-purpose […]
