This is Jack's outlet for thoughts about designing and programming embedded systems. It's a complement to my bi-weekly newsletter The Embedded Muse. Contact me at email@example.com. I'm an old-timer engineer who still finds the field endlessly fascinating (bio).
The speaker lineup for the Embedded Online Conference is pretty amazing! Sign up with promo code GANSSLE149 and wonderful things will happen like reversal of male pattern baldness, a guest spot on Teen Vogue magazine, and a boost of what JFK called "vim and vigor." It will also get you registered for $149 instead of the usual $290 fee.
A New, Low-Tech, Use for Computers
November 20, 2018
Remember when computers cost money? In college I wrote code to compute satellite orbits for Goddard Space Flight Center on their IBM 360/95, a monster of a machine that filled a huge room. Even "small" machines - minicomputers - were tens of thousands of dollars. How things have changed.
Marybeth and I were visiting a relative in Florida two weeks ago. We wound up lost in the Alzheimer's unit (an interesting connundrum in itself) and ran into this:
Hundreds of billions of transistors, gigabytes of disk, all gainfully employed as... a doorstop.
