Mystifying Marconi

My attention was recently drawn to an article in the Provincetown Independent entitled The Marconi Mythology. This makes the claim that “His ideas were derived from spiritualism, a pseudo-religious movement of the late 19th and early 20th centuries by which people sought to commune with the spirit world.” It also claims that Marconi believed that “sound never disappears from Earth” and that one could potentially construct a device to recover the sound of the angels singing in Bethlehem!

Unsubscribing from Zoom Release Notes E-Mails

Button labeled "Following" with drop-down menu open

For a long time now Zoom has been sending release notes to the e-mail account I used to register. I didn’t want this and so I scrolled to the bottom looking for a way to unsubscribe, but found nothing. I also searched the web where I found information on unsubscribing from meeting notifications, but nothing about the release note e-mails. Today I finally figured out how to unsubscribe.

Why All Capitals?

Q: Why do some users complete forms all in capital letters?

A: This is because early teleprinters and computer systems had no provision for lower case. Mixed case teleprinters came on the market in the 1930’s, but the standard US military teleprinter of World War II was the Teletype Model 15 (produced from 1928 to 1963) which only printed in upper case. This exposed an entire generation to official communications and reports typed in all upper case. This ‘official’ style was then duplicated by users of typewriters by engaging the Caps Lock toggle key.

Walking on Hypothetical Legs

On September 1st a number of news outlets published stories about the discovery of the skeleton of a whale with four legs. If true, this would lend support to the popular theory that whales evolved from a four-footed land animal which gradually adopted an aquatic way of life.

In most cases the story was illustrated by an artist’s conception provided by one of the discoverers of the skeleton:

Creature with crocodile like snout,
body of a skinny elephant, and long tail dives to attack snark lurking on
bottom

All of the news stories I read leave the reader with the distinct impression that the skeleton as found actually has four legs.

Radio Shack brand may return online

The Radio Shack stores played a big role in my childhood. My first memory of Radio Shack is from around 1975 when I was six. I went with my dad when he bought new speaker cables. We went others times whenever our TV stopped working. Dad would take the back cover off, pull out some vacuum tubes, and take them in to Radio Shack to use the tab tester. Sometimes there would be a line for the tester. If the tester said a tube was weak, dad would go over to a counter and ask the man there for a new one.
