    So I wanted to drop a pinned comment in here to acknowledge and share some of the really helpful messages I've gotten from folk clarifying Sabbath rules to me. I nearly married someone who was Jewish, so I'm very familiar with the hurdles of keeping a kosher kitchen, etc, but never having been Jewish myself I wasn't familiar with some of this and I have been interested to hear these details. 👍
    Here's what I've learned, thanks to folk like Indora and others who have reached out to me:
    * On the Sabbath the prevailing rule is that you shouldn't make *new* work or have others make new work for you.
    * With Sabbath Mode on elevators, the elevator is going to do the same thing we see it doing, regardless of whether or not it has any passengers. (Similarly, many observant folk believe that on the Sabbath you can step onto a moving escalator, but you can't make the escalator move if it was stopped.)
    * Many of the rules regarding power usage (even with modern electronic devices) are derived from the original Sabbath rule about fire: striking a fire is not allowed. (And most modern interpretations treat "turning on a switch" as "striking a fire")
    * But the Sabbath rules make distinction between striking/kindling a new fire versus maintaining a fire that was already going. So, again, making use of or somehow supporting the operation of an electronic device on the Sabbath may be seen as permissible as long as it was started before the Sabbath began.
    In conversations with folk, I pointed out that much of what Howard and I said during this section of the talk was regarding things like Beam-Break sensors and whether the presence of a human could be seen as "flipping a switch" in the elevator controller. But I did begin to understand more about not "making new work" etc etc.
    It was explained to me that things like the elevator's internal adjustments due to the presence of a person are secondary to the main work it was already doing: going from floor to floor. And also (I found this the most interesting, and I like how it is pragmatic and practical) "one can argue that the actions the elevator is taking are OK because they are *safety* actions. Nearly every Sabbath rule can be set aside for these. I know several observant Jews who use continuous glucose monitors and such to manage diabetes on the sabbath. Health and safety trumps everything else." (again, credit there to Indora)
    I like that and I appreciate all of you who have reached out to help me learn, on this and in comments on other videos, as well! 👍😁👍

      Not to be that guy, but who the hell cares? They are all made up arbitrary rules from a made up nonsensical religion. You should not be forced to change your behavior, just because your wife, friend, ect is religious. If it were the other way around, they would cry about you forcing your beliefs on them.
      Call me an ahole all you want, but I don't get this craziness at all.
      BTW, I am not talking about you specifically, but rather others that I have seen, especially as of late. This isn't directed at you so much as it is to everyone and no one.

      IIRC at least in come cases the beams are deactivated (but pressure sensors are not) when "shabbat mode" is activated, and so many of these secondary systems are also not fully active. Regardless there is still much debate whether use of a shabbat elevator is allowed, and by whom. Some ultra-Orthodox Jews do not use them at all, while some people hold that only those who need it (for accessibility reasons) should use one.
      The pragmatic side - which I liked you found interesting - is often the framework that guides the rules in Judaism. Safety and life above all else - even at the expense of the sabbath, then observance of the rules between you and your fellow person, then observance of the rules between you and God.
      edit: BTW - the use of a "sabbath goy" isn't as permissible or straightforward as pop culture has lead people to think it is. I can't just ask someone who isn't Jewish to do anything I want for any reason on Shabbat.

    • @artyboy92
      @artyboy92 3 года назад +28

      Your last point about safety is actually quite interesting and relevant to something my Dad told me. He is Jewish(he converted to Judaism as an adult) and I quite often quiz him about the rules of being Kosher and Shabbat etc. His brand is what's called Progressive Judaism, in contrast to the very strict Orthodox Judaism they take a more pragmatic approach to the rules. He mentioned a time where he went to a social dinner of some sort and the food was about as far from kosher as could be, something along the lines of a dish with ham/bacon and cheese in it. I can't exactly remember his words verbatim but he said something similar to "Sometimes it's better to be nice than right." That yes eating that food was not kosher, however eating that food was being a good neighbor and appreciating the efforts of a friend's hard work in the kitchen, in essence being a good guest, which I believe is touched upon in the Torah. I believe a lot of the interpretation of 'breaking the rules' has to do with intent, of course that judgement changes by the individual.
      On the other hand however he did tell me a story of when he visited an Orthodox Synagogue where one Friday evening the automatic lights had forgot to be set there was a crisis cause nobody could turn them on until my Dad offered to and one of the worshippers literally used my Dad's hand to turn all the switches on as if it 'wasn't him' who turned the switches on. That attitude is incredibly off putting and incredibly hypocritical since of course that worshipper drove to and from the Synagogue in his car. The difference I believe is the attitude behind it and the pragmatism.
      Of course it doesn't matter to me, I spend most of my friday nights happily eating ham and cheese toasties whilst using most of my electronic devices!

    • @GaviLazan
      @GaviLazan 3 года назад +9

      @@artyboy92 I would say that Orthodox Jews would probably politely avoid the not kosher food. There are ways of being a good neighbor without having to eat not kosher. If this was a life of death situation (let's say, he was stranded on a desert isle) then eating not kosher would probably be ok. When one needs to break the rules a lot of the emphasis is about the "why" and "how" - if it can be done in a way that is different than normal, better that way. If it's to save lives, that's permitted.
      In regards to your second story, I am very confused. If this was an Orthodox synagogue, they wouldn't be ok with your dad flipping a switch - since he is Jewish too, and definitely wouldn't use his arm to flip a switch. They also wouldn't have driven to synagogue, and if they did they would likely be ok with flipping a switch themselves. Either that person was trying to hide their "lesser" level of observance from the rest of the community, or something is missing from the story.

    As a twelve-year-old kid in the 1960's, I would spend hours playing in the elevator machine room at the hotel where we lived. It was fascinating to watch the equipment operating, and I eventually figured out how to manipulate the relays on the control board to make it do whatever I wanted. For example, when a passenger entered the elevator and selected floor 6, I could cancel the call and send them to floor 7. Other times, I'd send the elevator to the floor they selected but keep the door from opening, and then immediately return the car to the floor they started from. Things like that. Such fun!

    When I was a carpenter, working in a refinery, I got trapped inside an old Ottis elevator for five hours with a guy who was claustrophobic. Bad thing was, this elevator was on a running processing unit and the whole superstructure shook. So here we are, not able to get out, stuck between the 8th and 9th floor (industrial floors, 25’-30’), being slammed from wall to wall like being in a washing machine, not knowing if the “emergency call” button was connected to anything and it’s too loud to yell for help. Come to find out, the “emergency call” button wasn’t connected to anything and/or the light had burned out. No one knew we were in there until the elevator repair team showed up. The guy that was in there with me never rode that elevator again. He would always take the stairs…..

      I come from the land of expedition level cave exploration. Bad air is almost never a problem in the limestone caves of Kentucky: the air is good and flowing. But I know of accidents in caving where rebreathers were used, leftover from WWII. If you run out of O2 you don't notice because there's no CO2, which is what tells your body you need to take another breath. So you die not knowing anything's wrong.
      Another danger is open air cave pits (open to the sky) in southern Indiana. Dead leaves both plug the airflow, and generate CO2. Tragically, one person will rappel in and asphyxiate, and worse, not knowing the danger, their buddies die by rappelling down to save them.

A bunch of us piled in one and hit the up button.....well it didn't go up, it went down and felt like it was a free fall.. it stopped halfway where the building floor level was chest high so we had to crawl out. Apparently the motor started the wrong way due to being overloaded and it went fast enough the emergency brakes activated.
    The floor we crawled out on was a haunted house so lots of blood and gore , it was great !

    Waiting for the fire department makes me laugh. Myself and another rescue paramedic that happened to work in the emergency department with me, and who both have elevator rescue as certifications, nearly got fired, because we got asked to deal with a critical patient stuck in the main elevators. Turns out the elevators were functioning properly, the wheels on the patient beds were just narrow enough to fit between the car and the threshold if perfectly aligned. My coworker and I assessed the situation and lifted the bed up about 1cm with the sick patient on it and we gave each wheel a quick kick while we lifted. This critical patient and 6 staff had been stuck in an elevator at floor level with the doors open for 30 minutes before someone stepped out walked 70m to the ER to ask for help.
    I appreciate how many times you told people not to do stupid stuff, because so many people have no sense. But we people can't function in the other direction either, ie "something is wrong, but I've heard so much doom and gloom that I can't function if things work less than perfectly."

    On the section about being behind the times on security, and running on old windows versions, that’s so true.
    I’ve seen a badge system running on server 2008 r2, but the kicker was that we couldn’t upgrade the server because it needed the badge system licensing, and it was old enough that new licenses weren’t available, but the physical panels were too old and didn’t work with newer software.
    So they were stuck on ancient windows server, with old software, until they spent ~$15k to replace working badge panels

    I once got caught in an elevator with some buddies when drunk. We were jumping so obviously hit a failsafe and the thing just stopped dead. Emergency call button rang somewhere but no-one answered. Eventually we got hold of the fire dept (cell phone) and they did exactly what you said not to above. That is we climbed out with the elevator not level with the floor. Afterwards I believe they just 'turned it off and on again' and all was good. This got my thinking this should have been done with us still in the cab!

    She takes the stairs when possible, but that time wasn't possible.
    Had another friend that called the elevator in his building, then had a thought and decided to go back out, only to come back to a building full of police. Elevator came crashing with a guy inside from a high floor, guy didn't make it.
    These accidents are not common so it's weird I know these people? city ain't THAT big, i suspect no one takes proper care of their elevators. Mine is always off-floor and when fixed it stays fixed for a month.

    The one time i saw 7 used it was by a guy in full biohazard suit with a cylinder on a trolley. I came around the corner and went to walk in the elevator and he just looked up at us from the ground with his key turned and finger hovering over 7. "I'll get the next one mate no worries." Why does a four story building have 1234 and 7? wheres 5 and 6!! This particular building has a one kilometre long probe driven into the earth underneath it for seismic reading. Geoscience Canberra

    I was trapped in an elevator in a new building after an earthquake in the mid 80s. When I pressed the autodial emergency button, I got "You must first dial a 1 before dialing this number. Please try again." On a weekend. In an empty building.
    The sprinkler system had gone off due to the shaking (not due to a fire) and water was running down the shaft from the upper floors. They had contaminated the sensors so the hydraulic ram wasn't moving, it was just "jumping" a few inches every 20 seconds. I was hoping it would just settle to the ground floor. It didn't.
    I was able to get the doors open as it was almost at the bottom floor and crawled out.

      @sebastiannielsen 3 года назад +8

      Elevator license is usually not always enough. For example here in sweden, if you want to order access credentials to building sites, you BOTH need a license (credential that you have gone through the certification course) AND you also need a permission paper from your employer with his signature (to show that you are acting for a company, not acting "privately").
      And usually these credentials have to be paid by the company too, you can't pay them yourself. This to prevent people from "black-ordering" these in some company's name - by having it so the accounting will notice the bill if the credentials wasn't legitimately ordered by the company.

    Last time I nearly got stuck in an elevator was because of an issue with the 3-phase supply, caused the motor to burn out and filled all floors of the office building with smoke.

    Interestingly enough, I realised quite soon that I _had_ seen it before, but it was entertaining, so I watched it again :)

    Never in my life have I ever thought I'd watch an almost 1:30 minute video about elevators , yet here I am. Pretty entertaining I'll say.

    From the security point of view, no lock is ever safe but elevators could do one thing you don't ever mention here and that is to report potential security breaches. Meaning if security is a focus, there's going to be someone on guard and if someone turns the elevator to firefighter mode, it could sound an alarm on that person's desk leaving it up to them to decide if someone should go check it or if it's fine because the building is on fire. If that's not already being done, I'm surprised.

      In his other talks about elevators this is actually mentioned as a function of most elevator controllers. They often have extra dry contacts which you can wire into your monitoring system to indicate if it's gone into independent or fire mode. Modern ones I'd presume can do this all over network with the right integration.

    Oh, it's the video that led me to find you in the first place! Amazing. There's always too much information to remember...especially when it might matter! Rewatch = good

    I was once trapped in a lift by myself. None of the internal buttons did anything, including the alarm and intercom buttons. I got out by yelling and banging on the door until someone pressed the call button outside. It was a Schindler Lift BTW. I've been wary of lifts ever since.

      @@DeviantOllam I'm very interested in phreaking but I haven't seen the exact device shown at 1:12:44 do you have the name of the device, or know where I could find more information about. I hope this isn't something I should already know, you mentioned it like it's something every pentester owns. Thanks though amazing video.

    I once worked in an old 4 story building. The only elevator was a freight elevator. It had just two buttons - UP & DOWN, and you had to hold one in. The motor had two speeds - ON & OFF. It had only two cables (ropes). If we had a heavy load, it would bounce up & down when the button was pressed. There was a crude overspeed brake that made use of a separate hemp rope.

    Aww, I told you I'm bingeing. This was a great video and actually the 2nd of yours I watched a long time ago. The dude with you was like an encyclopedia of El knowledge, it was pretty fascinating. I think? that dude is the not so civil engineer, though I'm probably wrong. He's cool too, greta ideas and efficiency in all things UDT. Anywho, a good watch again.
