  • My dad was an electrical engineer that worked on the Gemini & Apollo programs. He actually worked at Draper Labs in Cambridge, MA which did a lot of work for NASA.

    He likes to tell the story of a coworker he shared an office with. This coworker designed a lot of the circuitry used in the rockets, and back then it was all drawn out by hand on huge sheets of paper on drafting tables. This guy was also fairly short, so he’d practically stand on a stool to reach the upper parts of the drafting table. He’d draw up various circuits, have the papers duplicated, and send the duplicates off to NASA. He kept all the originals on his desk. When it was time to draw up a new circuit he just put down a blank sheet of drafting paper over all the other circuit drawings and start drawing the new one.

    From time to time this guy would get calls from the NASA teams that were actually building the rockets. They’d say they were calling about a specific circuit, so this guy would start flipping through the corners of all the sheets of drafting paper looking for the right one. When he found the right one he’d duck his head under so he could get a good look at the circuit diagram while discussing it on the phone with the NASA people.

    If he had to then he’d actually crawl onto the drafting table during a call. My dad says that more than once he walked into the office to find this guy covered by sheets of drafting paper with only his legs & the telephone cord visible as he talked to the NASA engineers.




  • No, but it’s far easier to explain how to configure your home network such that 182.168.1.* is for your regular devices like laptops, etc. and 192.168.2.* is for your IoT devices. Then block all access from 192.168.2.* to the internet so your IoT devices can’t “phone home”, can’t auto-update without your knowledge, can’t end up as part of a botnet, etc.



  • Politicians routinely use the press in this manner to send messages to adversaries.

    A nephew of mine was serving on board the USS Hartford back in 2020 when they took a CNN camera crew under the Arctic circle and surfaced through the ice. You can find lots of similar news clips involving most/all military branches with just a little bit of effort.

    And back in the 60’s my dad worked at MITRE where he held a top secret clearance. He worked on a missile defense program that was so highly classified at the time that he said only about six people knew the full scope of it. A few months after a successful test, President Kennedy announced it during a state of the union address. My dad is convinced he was sending a public warning to the USSR about our capabilities.





  • Terrorism is all about terror.

    Imagine a major league football or baseball stadium packed to capacity. Two or three drones, each with a relatively small explosive charge surrounded by shrapnel fly in, crash into the spectators, and detonate. You end up with a small number of immediate casualties like what happened at the Boston Marathon. But the stampede of tens of thousands of panicking people trying to rush out of the stadium will probably injure and kill many more. Have a car bomb or two strategically located a couple blocks away where you expect those crowds to run and you’ve succeeded in your terror plans quite nicely…
