DEPENDENT TYPES AND HOW TO GET RID OF THEM

Dependent types are a programming language feature where types can depend on values, and the concept can be broken down into three ideas: functions returning types, input values determining output types, and tuple values influencing the types of other tuple elements. To optimize, compilers can erase values that are never used at runtime. Dependently typed languages often automatically identify and erase unused parameters.

MEMORY SAFETY FOR SKEPTICS

Memory safety is still important to understand, even with languages like Rust that are memory-safe by default. This means targeting practical strategies, like prioritizing memory safety in new code, targeting rewrites for critical components, and wrapping unsafe code with safe interfaces. While governments aren't banning C or C++, having better memory safety improves software performance and costs overall.
