Having a kid is the best thing you can do in life.

It's pretty much the worst; you bring a child to this world without their consent. And the kid will live through the death of their parents, and then unavoidably die themselves. Read about antinatalism

Do you regret being born?

Do you regret being born?

I do. Many others as well. The only solution to this problem is to not procreate

Swimming 3 times a week for about 45 minutes changes the body and mind. And is a little addictive like ex. running. Background: I've been swimming for the last few years for about 10-20 minutes twice a week and I've experienced the changes. Switching few months ago to more intense sessions led to dramatically higher rate of the change and I start to think about the ways of sustaining this. For now I've bought the swi…

I learnt how to swim this year (36M), and I've never felt better. I LOVE being in the water. It is an amazing feeling, and the cold water helps me calm down

I’m sorry to hear you feel that way. I can’t relate to those types of feelings but I sympathize and hope the best for you.

And then I got a bunch of geek friends together to cooperate with solving where the large explosions from the illegal fireworks come from. There are 5x in the group now with another couple coming online soon. Not to do anything with that except to confirm the science works over those distances, I was a kid once as well. Anyway, the goal now is to find physical evidence that the localization was correct. In my area, t…

This is cool, do you think this would work as a phone application? Does it do any kind of sound identification or matching? So if I sneeze around the device around the same time another system picks up a firework sound, will it be able to figure that out or is that a post process thing? Would be interesting for you and your friends to pick a very exact point on GPS somewhere in the middle of all you and light off a b…

Automatic matching is the next phase. Some people have done nice Phd projects on that have have posted github code. It will take a while to integrate that because there are very few gunshots here. First I want to establish what can we ultimately expect out of it and so that's manual testing. There are several big illegal explosions a week so there's test data enough. Likely when developing an automated system I'll have to detune it or train it on fireworks just so there's something to test against.

Currently I have about 7x people in a group so soon we will be able to test if you can localize an explosion from 5km away to something the size of a small car park, that being the case you have something to justify a bigger project in a place that really needs it.

There's another, less obvious usecase as well. Currently in the US there are innocent people being arrested and thrown in jail on the basis of the sound localization and no other evidence. If the people in those areas had their own localizer they could counter false arrest and challenge localizations that could well have been the result of bounces. I like the idea of a tool that can help fight against injustice.

Nice, I have been doing this twice per week two and the results in my mood are awesome. The waves have been a bit wild this week at my local beach but hoping it comes back to quiet to go back again
