Resolving git rebase conflicts

When a git rebase conflict occurs you will be presented with a conflict region (or “hunk”) that shows why the rebased commit couldn’t be applied to the base branch. To resolve a rebase conflict, your task is to apply the logically-intended (i.e. semantic) change of the rebased commit to the base branch.

CSS: The Important Stuff (Box Model)

CSS is one of those technologies that has a low barrier to entry (good thing 🎉), but because of this sometimes how it works can seem like magic. It's easy to get started writing CSS, so we quickly dive head first into it. Sometimes we smash our face into the concrete with frustration. Why won't my text move over yonder? Where did that scroll bar come from? How do I center this junk?

This is a series I'm starting called, "CSS: The Important Stuff". The goal is to take a dive into the mechanics of CSS so we can get a better intuition when styling and positioning elements. In part one we'll take a look at Box Model; the underlying layout of the web.

An invitation to category theory

Early in our mathematical education, we learn about a strong interplay between algebra and geometry—algebraic equations give rise to graphs and geometric figures, and geometric features can be encoded in algebraic expressions. It’s almost as if there’s a portal or bridge connecting these two realms in the grand landscape of mathematics: whatever occurs on one side of the bridge is mirrored on the other.

So although algebra and geometry are very different areas of mathematics, this connection suggests that they are intrinsically related. Incidentally, the `bridge’ that spans them is a but a dim foreshadow of much deeper connections that exist between other branches of mathematics that also may, a priori, seem unrelated: set theory, group theory, linear algebra, topology, graph theory, differential geometry, and more. And what’s amazing is that these relationships—these bridges—are more than just a neat observation. They are mathematics, and that mathematics has a name: category theory.
