  • This is one of the many edge cases that I’ve been convinced will keep self driving cars from becoming mainstream unless/until true AGI is achieved.

    A few years ago I stopped at a red light next to a construction site. I was watching the traffic light, so at first I didn’t notice a cop at the construction site trying to wave me through the red light. He finally took a few steps towards me and yelled to get my attention. Only then did I realize he was waving me through, so I did just that. I seriously doubt any current self driving car would recognize a police officer (and not just a random pedestrian) that’s overriding the traffic signal like that.

    Another edge case, coincidentally at the same intersection a few years earlier was when there was a car fully engulfed in flames as I drove up. I could hear sirens in the distance, and the cars in every direction were making sure to safely get out of the way of the approaching fire trucks. At least one or two cars cautiously crossed on the red to get out of the way. Again, I doubt any current self driving car would have navigated that situation anywhere nearly as well as a human.


  • Not exactly 911, but somewhat similar. A few years ago my wife & I were in a rental SUV while on vacation. It was a fairly new car with only something like 2000 miles on it. We were in the third lane of a 4 lane highway when a drunk driver hit us from behind with almost no warning. It caused our car to spin 360 degrees across 3 lanes before coming to a stop in the breakdown lane.

    Within about 5 seconds of the car coming to a stop we heard a voice asking if we’d been in an accident and were we ok. It turns out the rental car had one of those OnStar types of services. We were so pumped full of adrenaline that it was all just a blur as we tried to remember what highway we were on, near what exit, etc. We were so panicked… Luckily a state trooper on a routine patrol stopped maybe a minute later so we didn’t have to keep trying to figure out how to tell the OnStar person where we were.





  • IT professional for 20 years. C/C++ developer for 10 years prior to that.

    My first job out of college was mostly luck. I took a job doing tech support but after a couple of years was able to transition into development work.

    Virtually every job since that first one has been thanks to connections I made among coworkers. I got my current job because I knew two employees here. One of them was a co-founder of the company, and somebody I’ve known since the 1990’s and worked with at 3 other companies prior to this.










  • You would do well to go read up on the 1990 AT&T long distance network collapse. A single line of changed code, rolled out months earlier, ultimately triggered what you might call these days a DDoS attack that took down all 114 long distance telephone switches in their global network. Over 50 million long distance calls were blocked in the 9 hours it took them to identify the cause and roll out a fix.

    AT&T prided itself on the thoroughness of their testing & rollout strategy for any code changes. The bug that took them down was both timing-dependent and load-dependent, making it extremely difficult to test for, and required fairly specific real world conditions to trigger. That’s how it went unnoticed for months before it triggered.
