Why? Typically you age an article to contextualize it (sometimes REALLY important). In this case it is an interactive educational tool, the age hasn't changed its purpose, value, or usage.
HN regulars strongly prefer a year whenever it's not the current year, and the mods have confirmed that we should do so.
To all parents out there, it takes 10 seconds for a toddler to drown. Once in the water, if they go under, they tend to get disoriented and don't know where is up or down. When you are with your kids near a swimming pool or the sea, keep your eyes glued on them. My rule is "never break line of sight" (I borrowed the term from Assassin's Creed where if you break line of sights from the guards chasing you for a few sec…
> My rule is "never break line of sight" That's an actual law with children in Australia, idk about the rest of the world. <5 years old within arms reach, <10 years old within line of sight.

Of course the lifeguard has extra context by just being in the same space with these people beforehand. They're probably already watching certain people more closely before the video starts while you and I enter the space cold (and through a fixed window).
I wonder how people would feel about machine-learning enhanced lifeguard system. Machines are sharp all the time.

Why is there no progress bar? Do you really expect me to sit through several minutes of video of nothing happening just to prove a point? Finally I saw the child go down, so I wanted to rewind a few seconds to see what happened there. Nope, not allowed!
The site has an overlay where you can click on the drowning person and find out if you were correct. Hence the other controls are hidden.
I am impressed by these videos any time the pop up on hacker news. But one thing struck me: that they are using those large floatation rings. A lot of the incidents seem to be where a child looses contact to the ring and then cannot swim on itself. I am wondering, why they are allowed at all. In my personal experience, I have rarely seen such rings in public pools and that basically means, you are not getting far int…
They are just often misused - you are supposed to be supervising them when they are in the pool period and they only need deep enough water to keep their feet off the ground.

They’re also twirling their whistle which helps a lot, I’m sure.
When I took the Lifesaving merit badge, they said that lifeguards have to carry the whistle because it will get in the way if they wear it around their neck when trying to make a rescue.
In addition to what I saw in the videos, it could be interesting to learn how to spot the drowning person because it went unconscious or because of a cramp, etc.
One of the important lessons I learnt from a lifeguard is that movies depict a very inaccurate representation of drowning. The movies would have you believe that drowning is a violent and noisy event when in reality it is an inconspicuous and silent event. The victim cannot shout or call for help when they are struggling to keep their nose above the water level. Another important lesson I learnt that sometimes when s…
Being a lifeguard in a pool is clearly tough enough; being in charge of a stretch of sand with people moving in and out constantly has to be absolutely insane. Especially since a kid could run in, get smashed by a wave, and be underwater in the time you spent glancing down the beach the other way.
