My doctor, my financial planner and my trust attorney all roll their eyes when I tell them I intend to live to 100, but I am dead serious. Although I have yet to become a germophobic vegan gym rat, I am still drawn to click-bait like “10 ways to Live Longer and Better.” Beyond the no-smoking, moderate drinking, green leafy vegetable edicts, one standout is connections – being connected through healthy relationships is essential to longevity. Seventeenth-century Englishman John Donne foretold this with his oft-quoted “No man is an island”, noting that we all rely on others in one way or another.
Whether you believe that the physical world we inhabit was intelligently designed, or that it arose spontaneously through some improbable coincidence, it’s impossible to overlook many of the connections that surround us. A few of them are fairly subtle and call for the discernment of experts.
One such legendary though elusive connection is explained by Dr. Ian Malcolm.
“It simply deals with unpredictability in complex systems,” says Dr. M. “The shorthand is ‘the butterfly effect.’ A butterfly can flap its wings in Peking, and in Central Park, you get rain instead of sunshine.”
Dr. Malcolm’s credentials are well-established - he is the character played by actor Jeff Goldblum in the movie Jurassic Park. Whether or not a fly can produce the same effect by flapping its wings is left unsaid.
The technical term for this connection is Chaos Theory, which is based on the sensitivity of complex deterministic non-linear systems to small changes in initial conditions. Some of the confusion with respect to winged insects can be traced to the ad hoc father of Chaos Theory, meteorologist Ed Lorenz. For the record, Ed actually said something to the effect that even if we could account for every single butterfly, we still couldn’t predict the weather. If the flap of a butterfly wing in the Amazon really does cause a tornado in Texas, we will probably never know.
The world is full of connections that are very real, but that took some time to unravel. A familiar classic is the Tacoma Narrows Bridge which opened on July 1, 1940, in Pierce County, Washington. Construction workers noted how the bridge moved around on windy days, giving it the nickname “Galloping Gertie.” Engineers and consultants tried unsuccessfully to stop the motion until, on November 7, 1940, the structure collapsed in high winds. It was a decade later that the symbiotic connection between wind and bridge, now known as aeroelastic flutter, was established and the bridge was reopened.
If you are one of those people like me who sometimes plays music on your computer while working, don’t – that is, if your computer’s local files are stored on an ancient relic known as a hard drive. In 2005, a major manufacturer of HDDs for laptops noticed, in their testing lab, that Janet Jackson’s 1989 hit “Rhythm Nation” would crash the hard drive in the computer playing it. The song was so catchy that even nearby drives would sometimes fail as well. This connection was issued an official Denial Of Service identifier (CVE-2022-38392) by the U.S. government agency responsible for tracking security vulnerabilities. Ms. Jackson, the alleged hacker, was never charged.
In retrospect - considering all that physics stuff about sound, vibration, and resonant frequencies – the Rhythm Nation connection seems unsurprising and avoidable. After all, isn’t that the reason marching soldiers break cadence when crossing a bridge? But crashing a disk drive isn’t the only concern, and data center disk arrays are carefully engineered such that a frantic search for files on one will not cause data transfer interruptions or delays on adjacent drives. In 2009, Sun Microsystems engineer Brendan Gregg put together a video highlighting the dangers of a similar but little-known connection – yelling at the equipment. Note: this is a PSA for those network data professionals who occasionally shout and verbally threaten the hardware only to wonder why latency is spiking. You know who you are.
The famously inquisitive Leonardo da Vinci had this advice –
“Learn how to see. Realize that everything connects to everything else.”
Connections are everything for humans, machines, and combinations thereof. Discernment is key - not all humans, or computers, share your taste in music. Shouting at your human connections, or your data center hardware, can lead to poor performance or even catastrophic failure.
And perhaps most importantly, realize that not all connections are real – sometimes you are just flapping your wings.
