Linear types make performance more predictable by Jean-Philippe Bernardy and Arnaud Spiwack
Linear types for Haskell: "We can use linear types to manually, yet safely, manage data with malloc: because linearity forces the programmer using a value at least once, we can ensure that the programmer eventually calls free. And because it forces to use a value at most once, we can make sure that free-d data is never used (no use-after-free or double-free bugs). Anything that we malloc explicitly doesn’t end up on the GC heap, so doesn’t participate in increasing GC pause times."

A day in the trenches – The Old New Thing
"Product support calls let you participate in the other end of the pipeline. The software is written, it's out there, and now you have to pay for all your mistakes and bad designs when people call in with their problems. It's software karma."
