1 minute read Published: 2019-06-26

"Cognitive dissonance" is a fancy way of saying "I need to remember two (or more) different and contradicting things at the same time to understand this."

Things I Learnt The Hard Way - The Function Documentation Is Its Contract

Soulminder - Timothy Zahn

1 minute read Published: 2018-12-13

GoodReads summary: For Dr. Adrian Sommers, a split second of driving while distracted leads to tragedy-and obsession. His family destroyed, he devotes his entire being to developing Soulminder, a technology that might have saved his son as he wavered on the edge of death. Sommers's vision is to capture a dying person's life essence and hold it safely in stasis while physicians heal the body from injury or disease. Years of experimentation finally end in success—but those who recognize Soulminder's possibilities almost immediately corrupt its original concept to pursue dangerous new frontiers: body-swapping, obstruction of justice, extortion, and perhaps even immortality.
