Understanding Rust Lifetimes

Describes rust lifetimes, lifetime parameters.

Compares them to C++ pointers (in the sense they are difficult to learn, but make things explicit).

How to do distributed locking

This article explains the usage of locks (for efficiency - optimization / for correctness).

Explains the usage of the “Redlock” algorithm, to perform distributed locks. Explains a fencing mechanism (using tokens).

References monotonic clocks, stop-the-world garbage collection, consensus mechanisms.

Uses good diagrams for parallelism and concurrency.
