2. We are recovering from a network connectivity issue this
morning and restoring regular flight operations. United Airlines
8th of July 2015 400,000 passengers grounded
3. In our HyperConnected Modern World What is more of a threat?
Which will kill you sooner? CyberTerrorism Or Terrible Code
4. 1980 - NORAD reported that the US was under missile attack.
The problem was caused by a faulty circuit, a possibility the
reporting software hadnt taken into account.
5. 1983 - Soviet Nuclear early warning system malfunctioned and
erroneously reported incoming US missiles Officer in charge decided
to follow gut feelings that it was a false alarm
6. Potentially avoiding World War 3 ??
7. 1985 - Therac-25 Radiation Therapy Machine delivered a
high-powered electron beam with 100 times the intended dose of
radiation, delivering a lethal dose of beta radiation one-byte
counter in a testing routine frequently overflowed
8. 1991 Gulf War Patriot Missile System software had a delay
and was not tracking the missile launch in real time, thus giving
Iraqs missile the opportunity to break through and explode before
anything could be done to stop. In all, 28 were killed with an
additional 100+ injured.
9. 1994 - Scotland, Chinook helicopter crashed and killed all
29 passengers. Initially the pilot was blamed for the crash However
evidence rised that a software error was the actual cause
10. 2000 - Radiation Therapy planning software delivered
different doses depending on the order in which data was entered.
This resulted in massive overdoses 5 deaths where known potentially
21 died
11. 2003 - Race Condition Bug causes blackout across eight US
states and Canada affected 50 million people
12. 2003 - Computer software blunder at St. Marys Mercy Medical
Center in Grand Rapids, Michigan, that cost the lives of 8500
patients.
13. Well on paper anway they where actually alive
14. Real Deaths by Terrible Code = 78 False Deaths by Terrible
Code = 8500 Deaths by CyberTerrorisim = 0
15. Software will EAT the WORLD Marc Andreessen Wall Stree
Journal, August 2011
16. As Software EATS the WORLD Quality of Code becomes not just
important but a nessecity Its not just a website going down there
are human lifes at stake
17. In the olden days Infrastructure was built to have
99.9999999% uptime Modern Containers and MicroServices architecture
allows us to design infrastrcture for failure
18. We need to architect our software for failure We need to
accommodate for failures Software Bugs should NOT take a system
down Fault tolerant Code Design Patterns
19. There are Human Lives at Stake
20. Education is Key Admitting we dont know everything Asking
for HELP Learning from Each Other Test Driven Development Continous
Quality Control Build Checks into Release Cycles
