  • I remember living in a world where i was shocked when companies started asking for credit card details when activating a free trial.

    I’m signing up for a free trial. I shouldn’t need to even give you my name. Just put a 30-day limit on the key i activate the software with. If i want to buy it, then i can decide that during the trial.

    The fact that we are at a point where the anger is directed to the part AFTER i have given all my details and credit card info is so painful to see.

    There are a few things they could try. You can get biodegradable bottles, you could use glass or metal, there are cardboard bottles and silicon and even ceramic.

    You could also change the way we buy these drinks from bottles we buy and throw away to containers we keep and refill from dispensers. The infrastructure isn’t there for it, but with the amount of money the major drinks companies make its not unreasonable to assume they could afford to implement it.

    And arguing that these alternatives are not practical is a wasted effort because an alternative IS needed to stop mass plastic waste and protect the environment so we need to get used to the bar being set at a different height.









  • I’ve had a look into it, and it doesn’t work if you try to do it mathmatically. You always need more than 3 gos on the seesaw.

    There is a solution in the replies to my original comment that is the actual solution, and it works every time and is much simpler than any grouping method.

    It involves assigning a letter to each person and then aligning that with a grid of positions “left” or “right” or “none” on the seesaw. Over the three rounds. So, person A is on the right all three rounds person b is on the right for 2 rounds then on the left for the 3rd round.

    You end up with a list of 12 patterns that do not repeat or mirror any other pattern like “LLL” “LLR” “LRR” “LR-” etc. Then you do all three rounds and compare the position the seesaw was in with those patterns.

    If the seesaw was down on the left 2 times the down on the right the third time then you look for which person had that pattern in this case it was person B. So they are the one with a different weight and they were heavier.

    Equally, if the opposite pattern occurred. It was down on the right 2 times, then down on the left for round, then that is the opposite pattern of person B and does not occur anywhere else, so it was person B, and they were lighter.

    person:  A B C D E F G H I J K L
    
    round 1: L L L L R R R R — — — -
    
    round 2: L L R R R — — — L R L -
    
    round 3: L R R — — L R — L L — R
