The Queen of code

-

You probably don’t know the name Grace Hopper, but you should.

As a rear admiral in the U.S. Navy, Hopper worked on the first computer, the Harvard Mark 1. And she headed the team that created the first compiler, which led to the creation ofCOBOL, a programming language that by the year 2000 accounted for 70 percent of all actively used code. Passing away in 1992, she left behind an inimitable legacy as a brilliant programmer and pioneering woman in male-dominated fields.

Hopper’s story is told in “The Queen of Code,” directed by Gillian Jacobs (of “Community” fame). It’s the latest film in FiveThirtyEight’s “Signals” series.

The History of Julius Maggi MAGGI owes its name to founder Julius Maggi (1846 - 1912), entrepreneur and inventor of the first product to bear the brand - MAGGI Soup Seasoning. Born in Frauenfeld, Switzerland, Julius took over a hammer mill from his father in 1869. At the time the milling industry was in crisis so Julius decided to open up new areas of production. He got in touch with physician Fridolin Schuler who had a concept for improving the nutritional content of meals for the labouring classes by making packaged foods out of milled pulses or legumes. Together they began product development and after two years of experimentation, the first industrially produced leguminous flour was put on the Swiss market in 1884. When the expected market breakthrough failed to occur, Julius went back to the drawing board and created MAGGI ready-to-use soups in in 1886, then launched MAGGI flavouring later in the year. More and more new products followed between 1887 and 1889. Julius op

The following are   NASA's plan if an asteroid is heading to Earth  Step 1: A text message would be sent to a team of 12 scientists.  Step 2: The scientist immediately start tracing the asteroid's path  Step 3:  They measure the size of the object and predict the time of impact  Step 4: They confirm with authorities whether the impact is unavoidable.  Step 5: A public statement would then be issued. Photo by  Bryan Goff  on  Unsplash Then NASA and emergency agencies how best to protect the Earth. They have simulated this experiment many times and come up with a few defensive options. They include firing lasers into the asteroid. Crashing a spacecraft into an approaching asteroid is another possibility. As is detonating a bomb next to an incoming object. There is no risk at the moment though. NASA can't detect any asteroid currently heading towards us. No large object is likely to strike for at least several hundred years.
