Linear programming explained as skating downhill
Linear programming is an algorithm that solves the general problem of maximizing a linear outcome given linear constraints. This includes the very broad category of problems "Given a limited of resources, objectives using those resources, and a value for each objective, how can I output objectives to maximize value?". What exactly does this mean though, and how can we solve these kinds of problems? Let's go over it, using skating downhill as an analogy to help us understand both what these problems look like and what solving them looks like.

The 2038 Problem
The "2038 Problem" stems from how Unix-based systems store dates and timestamps using a 32-bit signed integer, which can only represent seconds up to 2147483647 since January 1st, 1970. Once this limit is reached on January 19, 2038, at 03:14:07 UTC, an integer overflow occurs, potentially causing disruptions in various systems that rely on accurate date and time recording.
