Hiring a new assistant

A business was hiring a new assistant. They put out ads everywhere. A couple of days later, a surprise visitor appeared at their office: a dog, holding a newspaper. The dog pointed to the hiring ad with his paw. The manager, though intrigued, was skeptical and decided to challenge the dog:
" I need a someone who can use a computer."
Without hesitation, the dog hopped onto a desk, powered up the computer, and even printed a document.
Impressed, the manager continued, "Okay, but can you work with spreadsheets?"
The dog promptly opened up Excel, swiftly inputting data and generating graphs.
Nearly speechless, the manager had one last test: "All that's impressive, but can you speak another language?"
The dog replied:"Meow"

First Audion tube

In 1906, the first triode was ordered by Lee de Forest who instructed the New York automobile lamp maker, H. W. Candless, to make a glass bulb containing a "grid" wire between a filament and an electrode plate. These specifications extended the Fleming two-element diode valve design previously published in the Proceedings of the Royal Society. The third element - the grid wire - regulated the flow of electrons between the filament and the anode plate, producing an amplification of the variations in a signal voltage applied to the grid. De Forest named his invention the "Audion." Within a few years (1913-1917) he was able to profit from his patents that he sold to AT&T for a total of $390,000.«[Image: A de Forest Audion tube, circa 1912.]
