Today is Ada Lovelace Day, a day to celebrate and encourage women in the fields of science and technology. The day is named after Augusta Ada King-Noel, Countess of Lovelace, born Byron. (You can see why we just call her Ada Lovelace.) She was a brilliant mathematician, and the writer of what’s probably the first real computer program — it computed the Bernoulli series. At least according Charles Babbage, in correspondence to Michael Faraday, she was an “enchanted math fairy”. Not only a proto-coder, she wrote almost all of the existing documentation about Babbage’s computation engine. She’s a stellar example of a brilliant and unique individual. If you were looking for a superhero to represent women in science and tech, Ada’s a good pick.
In our minds, she gets stiff competition from Marie Curie. Curie did fundamental research on radioactivity, is one of two people with Nobel Prizes in two different sciences, and got to name the two elements that she discovered. 2011 was the Year of Marie Curie in France and Poland. She has her own year in addition to her own unit. Even Spiderman doesn’t have those radioactive super powers!
Don’t Need Another Hero?
But on a day dedicated to getting more women into the technical arts, it’s also a little bit daunting to pick Lovelace or Curie as a symbol. Are you ever going to have something that equals “first computer program” or “two Nobel Prizes” on your résumé? We aren’t. It’s great to have heroes, but maybe we need more than just heroes — we also need mentors.

MIT’s Computer Science and Artificial Intelligence Lab, CSAIL, has created a process of teleoperating a Baxter humanoid robot with an Oculus Rift VR headset. This project is partially aimed towards making manufacturing jobs
a hell of a lot of fun telecommutable. It could even be a way to supervise robot workers from a distance.
In a nutshell, the user controls the robot remotely in a virtual reality environment. The user does this specifically in a VR environment modeled like a control room with multiple sensor displays, making it feel like they are sitting inside the robot’s head. By using hand controllers, users can match their movements to the robot’s to complete various tasks. If you’ve seen Pacific Rim, you are probably envisioning a Jaegar right about now — minus the psychic linking.

[Stephen Edwards] had some time one Christmas. So he took a DE2 FPGA board and using VHDL built a pretty faithful reproduction of an Apple II+ computer. He took advantage of VHDL modules for the 6502 CPU and PS/2 keyboard, and focused more on the video hardware and disk emulation.
According to [Stephen], you can think of the Apple II as a video display that happens to have a computer in it. The master clock is a multiple of the color burst frequency, and the timing was all geared around video generation. [Stephen’s] implementation mimics the timing, although using more modern FPGA-appropriate methods.
