SENG 440: Lecture 4 – Task Scheduling and Activity Lifecycle

Dear students, Last time we saw how activities and layouts get married and make the screens of our apps.

We’ll look at ConstraintLayout, updating the user interface without user interaction, […]

Intervals in Deltaphone

The nobler agents of educational reform will also tell our kids that programming is a creative exercise that will make them better thinkers in other […]

SENG 440: Lecture 3 – Activities and Layouts

Flatcaps in Libigl

Madeup’s dowel solidifier has one job: thicken a sequence of line segments into a solid. But what if the sequence isn’t a polyline, but rather a branching structure like a tree or a fork? One could model each branch as a separate dowel and hope that nobody looks too closely at the joints, but that’s […]
