SEO and AI, but not sketchy

Andrew Laws

Thoughts on Carbon

Phil Nash

with Phil Nash

The world runs on C++ - but it has a reputation for being unsafe and complex. While alternatives, like Rust, exist they lack sufficient interoperability with legacy C++ to really take over the mantle. Carbon has been designed with this goal at its centre. But how does it stack up? Can it take over? All I can do is give my opinion, as a user of many languages, but three decades of history with C++.

How to 10x learning a new programming language

Raymond Coulstock

with Raymond Coulstock

What is simplicity and why do we value it so much? How does it relate to complexity? When is complexity good and when is it bad? How does simplicity differ from ease? As we examine these questions we'll find that the situation is not quite as simple (!) as it might first appear. In the course of the discussion we'll come up with a mental model for framing problems that we can apply to many things - but we'll particularly look at how we can apply it to our designs and code. We'll also look at how some programming languages help us more than others in our drive towards simplicity.
