See, I’m not unattractive, the lighting’s just wrong everywhere.
Dumbledore would have been happier than anybody to think that there was a little more love in the world.
Rear Admiral Grace Hopper would have been 107 today, and is being honored with a great Google Doodle. It’s quite literally impossible for us to imagine, as we sit here reading about her on the internet, but people used to use things like paper and pencils and chalk and slide rules to solve (and often not solve) complicated problems. Grace Hopper quite simply helped usher in the modern age, her impact, I think, is no less than the steam engine or the cotton gin.
Some awesome stuff she did: Grace Hopper developed first compiler, allowing computer calculations to move beyond simple arithmetic and into more complex problems. She also developed first standardized computer language, COBOL, which laid the groundwork for all the languages we use today.
One day she found a dead moth disrupting one of the electronic relays in the Mark 1 computer, and upon removing it (and fixing the computer), the term “debugging" was born. Here’s her daily log from that day, with the offending moth taped to the page:
Beyond that, she was a charming scientific communicator, and she possessed a marvelous ability to make people, and mind you this was in a time when almost no one owned their own computer, truly appreciate both the importance and the complexity of computing technology.
She famously carried around a bundle of nanoseconds in her purse for illustrative purposes. Here she is charming the socks off of David Letterman, and giving him a nanosecond of his very own (don’t miss the picosecond joke, either) :

"In my view, the defining feature of digital language is that it quantifies whatever is put into it and makes it granular. Ambiguity and fluidity are represented by strategically arranging unambiguous and discrete units. When quantifying color digitally, people had to ask what a suitable unit size would be, and as i understand it, in the standard digital RGB space, there are 256 possible values of each primary, so you get more than 16 million discrete colors.I personally I love the RGB cube because of it’s elegance and relationship to the way we perceive space. Each of the three light primaries— red, green and blue— is assigned an axis , and the cube is essentially defined as the area within which the values for red, green and blue go from 0% - 100%. At the origin, where all three values are zero, there is no light and so that corner of the cube is black. At the opposite corner where all three values are a 100%, there is all light and so that corner is white. The other six corners of the cube are the light primaries and light secondaries, which also correspond to the process primaries - cyan, magenta and yellow.”
