DESCRIPTION
An introduction to Taleb's idea of antifragile and how it's useful when thinking about computer systems.TRANSCRIPT
Antifragility@dlutzy
Fragile Robust
Fragile Robust
Antifragile
Fragile Example: glass
Shatters when exposed to even a small stressor.
Robust Example: steel bar
Resists even a large amount stress. But is inflexible. When exposed to enough stress it breaks.
Antifragile Example: muscle
When exposed to stress it gets stronger.
Is this idea applicable to computer systems?
“if antifragility is the property of all those natural (and complex) systems that have survived, depriving these systems of volatility, randomness, and stressors will harm them.” - Taleb
Without change something sleeps inside us, and seldom awakens. The sleeper must awaken.
- Duke Leto Atreides
Antifragility is all around us, if we look for it.

Continouous integration/deployment == antifragile
Legacy systems == robust or (more likely) fragile
