Intersection of Art and Chip Design circa 1990

In 1990, I was working as multipurpose software sales, marketing, fill in engineer, for Synergy Computer Graphics. One of the most interesting things to happen, was the need to plot some very large cool chip plots for some cool chip companies. The internet had not taken off yet, so I received tapes from Intel, TI, etc.

Because I had a keen eye for color, and how fill patterns worked with overlap in color, I got the assignment. 20 plots in one week.

Here as the announcement from Moma.org

Here was the book on Amazon

Why did this job go to Synergy Computer Graphics (later absorbed into Nippon Steel) ? Because at that time, they had a patent on single-pass four color plotting and the only device on earth that could do it. The device was large, but fast. All other devices did 4 colors in 4 long passes of the rolled up plotting paper. These sold for $125K at that time.

Visual Recall Devices for Electrodynamics formulas

Ingenious use of hand shapes to recall the structure of formulas in Electrodynamics. The kernal of this wisdom is that the hand is one of the few “devices” that must be allowed in any testing situation for students. Yes, I know there is an iPhone app for each formula that plots in 3D, etc. But what if you had solve these equations after a ship wreck?

Coordinate Transformation Rules

When I was a kid it took me a long time to learn this.  So, I thought it would useful to put a link to it here.  The transformations are from rectangular to polar, cylindrical and back in a useful structured approach.

This is a link to Dan Fleisch’s site for his book.  He is an Associate Professor in the Department of Physics at Wittenberg University, where he specializes in electromagnetics and space physics.  He is the author of A Student’s Guide to Maxwell’s Equations published by Cambridge University Press in 2008

Green Marketing Case Study: Is it really good for you?

Earth Shoes.  “They are good for your posture and good for the earth”.  How convenient is that? Finally some inventor did the right thing, designed a prosaic object such that both entities that came in contact with it benefited enormously [environmentalism]. And at that time there were no forums, no social media, no websites, no internet to “rise up and reveal the lie”.

On April 1, 1970, a new shoe shop opened its doors for business on East 17th Street in Manhattan.  The owners, Raymond and Eleanor Jacobs, soon began to see throngs of hippies flocking by on their way to Union Square to celebrate the first ever Earth Day. In a flash of brilliance, the Jacobses wrote a sign advertising “Earth Shoes” and stuck it in the storefront window.  What used to be plain footwear suddenly became a generational phenomenon; for the better part of the next decade, so-called Earth Shoes were a staple of the American environmentalist’s wardrobe.

The Earth Shoe phenomenon was not just a right-place, right-time aligning of the stars.  It was the first—and perhaps the most successful—case of green-stamping.  Now a well-established practiced, green-stamping involves marketing a product for its environmental benefits.  Seems simple, yes?  The problem lies in the discernment between true sustainability and fakery.  The case study of the Earth Shoe can help shine a light on our own susceptibility to false green-stamping, and let us see clearly the consequences of being duped.

The manufacturing of Earth Shoes, as you can gather, had no connection whatsoever to the environmental ideals promoted by Earth Day.  However, the podiatric craze was filtered through the underlying fabric of a broader social movement, and so it was accepted without much fuss.  It survived for so long because of its unquestioned linguistic connection to early environmentalism (perpetuation by cultural contact high, if you will).

Where does Big Data come from?

Searching for all green technical images, I found this one.

Where does big data come from?
How are they getting all this data?

 

 

 

 

 

 

 

 

 

Some of the many sources for online data collection going on every second, 24/7, every day:

  1. Surfed several websites gathering info for a presentation – My connectivity provider (Sprint) and Google added more info about me inside their already significant repositories
  2. Paid a few bills online – Credit card companies not only have my original transactions and buying habits but now they know my payment tendencies as well
  3. Downloaded a movie from iTunes for my trip – Apple adds this to the profile I have been populating for almost a decade
  4. Called my wife from my mobile phone to her car phone – Sprint and OnStar just got some more info about usage time and calling locations
  5. Printed boarding passes for a flight – Southwest knows where I have been, where I’m going and my general flight patterns.
  6. Drove to the airport – Sprint knows roughly the path I took from Home to the airport via my mobile phone switching between cell towers.
  7. Browsed email and some apps on my iPad – Apple and who knows what app developers just gathered access and some location data
  8. Landed in Los Angeles, El Paso & Dallas – Phone turned on at every stop and has tracked some level of information on my location and calls.
  9. Got into rented car and drove to meeting site – Hertz captures the location, type of car, duration etc. Plus Sprint knows roughly where I’m at too.
  10. Checked into room and had dinner – The hotel and credit card companies have that covered and logged.
  11. Browsed a few websites, email and writing an article – The hotel network and connectivity provider logged everyone of them, I promise.Read more herehttp://www.tjcrawford.com/2012/02/17/big-data-is-everyday-data/
