As part of the winnings, Adobe is donating software and 3D printers to Waters' school in his name. "The semaphore had been transmitting the audio broadcast of Neil Armstrong's historic moon landing in 1969," reports The Mercury News. "That's right, not the text but the actual audio." The report provides some backstory: "Waters discovered the project, San Jose Semaphore, last summer while he was looking up something about Thomas Pynchon's 1966 novel, 'The Crying of Lot 49.' The text of that work was the code originally programmed by New York-based artist Ben Rubin in 2006. Seeing there was a new message, Waters began trying to decipher it while watching and writing down the sequences online from Tennessee. He discovered a pattern that led him to believe it could represent a space -- or a silence -- in an audio file, and when he graphed the results it looked like an audio wave. He dismissed that as being too difficult but came back to it and eventually ran his results into a program that would convert his numbers to audio. The first results came back sounding like chipmunks squeaking. So he tweaked things and found himself listening to the historic broadcast, which ends with Armstrong's famous line, 'That's one small step for man, one giant leap for mankind.'" You can listen to the semaphore message here.

When I joined almost 10 years ago I was in good company with peers who were very computer literate -- able to develop their own complex excel macros, be their own IT tech support, diagnose issues communicating with or operating instrumentation, and generally dive into any technology-related problem to help themselves. In 2017, these skills and tendencies are more essential than they were 10 years ago; our instruments run on modern OS's and are network/internet-capable, the heavy data processing and analysis we need to do is python-based (SciPy, NumPy) and runs on AWS EC2 instances, and some projects require engineers to interface various data-acquisition hardware and software together in unique ways. The younger generation, while bright in their respective engineering disciplines, seems to rely on senior staff to a concerning degree when it comes to tech challenges, and we're stuck in a situation where we've provided procedures to get results but inevitably the procedures don't cover the vast array of scenarios faced day-to-day. Being a small company we don't have dedicated IT specialists. I believe I gathered my skills and knowledge through insatiable curiosity of all things technology as a child, self-teaching things like Pascal, building and experimenting with my own home LAN, and assembling computers from discrete components. Technology was a fringe thing back then, which I think drew me in. I doubt I'd be nearly as curious about it growing up today given its ubiquity, so I sort of understand why interest might be less common in today's youth.

How do we instill a desire to learn the fundamentals of networking, computing, and coding, so that the younger generation can be self-sufficient and confident working with the modern technology and tools they need to perform -- and be innovative in -- their jobs? I believe that the most effective learning occurs when there's a clearly useful purpose or application, so I'm hesitant to build a training program that consists solely of throwing some online courses at staff. That said, online courses may be a good place to get some background that can be built upon, however most that I've come across are intended for people pursuing careers in computer science, web development, software engineering, etc. Are there any good resources that approach these topics from a more general purpose angle?
