Software is all about logic. Programming has garnered a reputation of being a field that is heavy on the math and crazy equations. And computer science seems to be at…

Now that we know that the abstract syntax tree is important (but not necessarily intimidating!), we can start to dissect it a tiny bit more. An interesting aspect about how…

Okay, so now we have two trees to keep straight in our heads. We already had a parse tree, and how there’s yet another data structure to learn! And apparently,…

Before I started on this journey of trying to learn computer science, there were certain terms and phrases that made me want to run the other direction. But instead of…

The differences between interpretation and compilation and their respective translators tells us a lot about how these two programs are implemented. If we compare these two methodologies, we’ll start to…

There is perhaps nothing more satisfying than seeing the pieces of a puzzle come together. This is the case for actual puzzles, which I am pretty bad at because I…

New "classification models" sense how well humans trust intelligent machines they collaborate with, a step toward improving the quality of interactions and teamwork. The long-term goal of the overall field…
