  • At the end of the interview when they ask “do you have any other questions for us”, if it went well and you decide that you want to work there, ask about what your first day looks like compared to an average day after you’re settled in.

    This can be a little social engineering push to have your interviewer shift their perception of you into someone that is already hired.







  • Im not sure exactly how the system works, but if I were designing one, there would be 3 approaches I can think of.

    The first is to equip the lock with a GPS system and dictate that it locks if it’s not within range of a particular location. This one would be the most expensive to implement, but should come with minimal opportunity for messing with it.

    Next down the list is each lock is equipped with a radio to connect to a wifi or sub-GHz broadcaster, and as soon as it misses enough heartbeats to a central control point, it locks the wheels. This could be disrupted by jamming the signal, but jammers of this type are highly illegal, and easily trackable.

    Last is the cheapest option, which is to include an RFID module tied to the lock and a system to broadcast a signal at the perimeter. If a cart comes within range for a long enough period then the RFID tag is activated and the wheels lock.

    I suspect it’s probably a sub-GHz radio situation, with the broadcast power tuned to be within a few hundred meters of the store. If you had some kind of SDR you could probably pinpoint the signal they use and repeat it, letting you wheel a cart outside the zone, but as soon as you stop the signal the wheels will lock.

    “The brand new car I bought has been out of commission for roughly 25% of the time Ive owned it. Is it a bad car?”

    “All the people telling me this car is bad are wrong because it’s the best car in the world, but my question still stands. Is it a bad car?”







  • I work in an office as a network administrator. Largely my day to day is a meeting every morning to go over what everyone is doing for the day, then looking through and responding to all the alerts that came up from all the servers I manage(things like failing backups, unexpected reboots, stopped services, strange login behavior, etc)

    Then, if I still have time in the day, I put time towards some of the long term projects I have which largely consists of finding things that can be automated and scripting up solutions to that
