<i>Upside</i>, October 2001 <br><br> <p> In discussing the development of semiconductors in Silicon Valley, many roads originate with
Arnold Beckman, the man who hired William Shockley away from Bell Labs and brought him to the San Francisco Bay area to establish the Shockley Semiconductor Labs of Beckman Instruments (now Beckman Coulter). Semiconductors had been around for several decades - odd materials that had the ability to conduct electricity under certain conditions. They are, Gordon Moore says, "halfway between insulators and metals. The wonderful thing about semiconductors is that you can control the amount of their connectivity through introducing impurities."<p>Bell Labs, as the research arm for the Bell companies - owners of millions of electromechanical relays across the nation used in its telephone switching networks - was one of the most interested parties in semiconductors and their ability to conduct electrical currents. Bell executives had the foresight to hope that, one day, Bell could repl

Catastrophic Failure
On my part.
I've got a sheets backup from July 25 2016 restored.
I'm going to vomit, then hide for a bit and then get a postmortem up.

Useful bookmarklets for better-looking browsing: remove nuisances and improve readability

Some bookmarklets for improving the appearance and usability of websites.

See also rdd.me aka readability.com who have a bookmarklet which usually reformats just the main text of a page into a readable format, and can also email or send to a Kindle.

blacktext - change text to black to improve contrast allgrey - change background colours to grey, which I find much more relaxing greenlinks - make hyperlinks dark green which shows up better zapit - delete an annoying element like a sidebar or header or footer greythis - make one element's background colour grey, in case allgrey missed it
