Many years ago, when I was an undergraduate CS student, my professor informed me that the Boolean Satisfiability problem was NP-Complete. I took this to mean it was not something I should waste any time thinking about or expect to be a useful tool in the future.

Enterprise architecture feels like a conceptual mountain of technology – which unfortunately is true. Organizations today are investing in endless platforms, software, and features, much of it is AI. Enterprise Architects is a role many leaders don’t know they need until it’s too late, resulting in continued silos and cumbersome processes that cost too much and don’t provide business value, but stick around because the c-suite committed to investing in it despite not understanding it.

AI tools are writing more code than ever, but how much of that code will your team want to maintain six months from now? As coding agents become a daily part of development, many teams risk drowning in bloated, inconsistent, and unreadable code.

Traditional object-oriented approaches are often intrusive, relying on (public) inheritance and runtime polymorphism. There are upsides to these approaches, of course, but there are quite a few downsi...

We all hate legacy code and want to modernize our old systems. But the journey from the architecture we have now to the shiny new modernized system we want to have can be long.

Algorithms + Data Structures = Programs -- a famous book title from the late Turing award winner Niklaus Wirth that tells us what a program is. What makes programming creative is how we wield algorith...

For years we’ve built design systems on top of frameworks like React, Vue, Angular, Svelte - and we’ve paid the price with rewrites, migrations, tight coupling, performance overhead, and endless fragm...

AI coding assistants are rapidly becoming part of every developer’s workflow, but what happens when the very tools meant to help are turned against you?

One of the top goals of the Carbon Language project is to have an absurdly fast compiler and toolchain. Much of this stems from leveraging the ideas of data-oriented design to make the data structures...
