On the topic of doors. I have a hack that speeded up transit and benefited many many people daily.

There was a main entrance gate at my old high school. There was four sets of double door that opened out, that allowed students into the campus. These doors are damn heavy and one night I was cruising with my friend and I told him, I got an idea. I refused to answer any of his inquiries.

We arrived at the high school, I climbed up onto the top of the gate. On each door was the little hydraulic system to stop the doors from slamming shut ( know what I'm sayin?) These hydraulic arms were just little planks of metal. I pushed them down with my foot. This created tension when the door closed on the two arms. Instead of sliding freely(and the door closing), the arms rub and create enough friction to hold the door open.

Now instead of the doors swinging close, they remain open daily, until they are closed for the night. Every day I would walk through them, and see every other student walking through my simple little hack that got the doors to stay open all day.

tl;dr: Hacked some doors at my old high school so they would stay open instead of closing.

Edit: My logic is: I used the doors... four times a day average. Took three seconds to open and walk through vs one second to just walk through. So two seconds to open. About 180 days of school times four years.

180x4x2/60= 24 minutes

While not substantial, I just saved a person 24 minutes of their life.

Here is a hack for you: Doors that are hung slightly off center or with self closing hinges close mostly for convenience. Hydraulic or electrical closers like you encountered are more expensive, and only installed when they are required for some reason (security, child safety, fire doors, etc).

You mentioned four sets of double doors, which also indicates the designer knew the requirement for positive closure would be a flow issue and added extra doors. Had there not been a really good reason for having the doors be closed they probably wouldn't have planned for the extra doors.

I know you believe your "hack" was innocent enough, but essentially you vandalized a system someone carefully thought out to save yourself 24 minutes over 4 years.

I don't know the architecture of your high school or the reasoning behind the positive closure doors, but I hope to god they were not part of a firewall (walls and closed doors designed to prevent fire from spreading through a building faster than it can be safely evacuated).

Like. I do these type of time-saving calculations in my head whenever someone like the bus driver drives too slow and fails to make a light, thus costing everyone on the bus an extra minute of their lives.

You actually saved 24 minutes times, say, 3000 students, which is 24*3000/60/24 = 50 human days saved over the span of four years. Not to mention, this hack may well have lived on since you've graduated, so that's many more days of savings. Nice.

And then you starting calculating how much time you spent in the bathroom and hopefully you realise that time is not the essence of life.
