This week we’re recognizing astronaut and aerospace engineer, Neil Armstrong. After serving as a naval aviator from 1949 to 1952, Armstrong joined the National Advisory Committee for Aeronautics (NACA) in 1955. Over the next 17 years, he was an engineer, test pilot, astronaut and administrator for NACA and its successor agency, NASA. Armstrong transferred to astronaut status in 1962 and was command pilot for the Gemini 8 mission, where he performed the first successful docking of two vehicles in space. As spacecraft commander for Apollo 11, Armstrong became the first man to land a craft on the moon and the first human to step on its surface.

Whether you pronounce it “Jif” or “Gif,” the graphics interchange format (GIF) improved on black and white image transfers with 256 colors, while still retaining a compressed format that slow modems could load easily. Steve Wilhite of CompuServe was the engineering lead on the team that adapted the GIF file format in 1987, which became the standard for 8-bit color images on the Internet until PNG came around. Although there is no official first GIF, Wilhite thinks the first GIF was a picture of a plane.

Alexander Graham Bell originally suggested 'ahoy-hoy' be adopted as the standard greeting when answering a telephone. Ahoy-hoy derives from the term “ahoy”, which is generally thought of as a nautical term used for hailing ships. Ahoy-hoy was later replaced when “hello,” suggested by Thomas Edison, became common.
