The current experiment in São Paulo, 8k+ cameras were added to the city with the same justification: security.
But, at least for smartphones robberies, the results are not obvious: on an average of 24 smartphones stolen every hour[1] in one neighborhood (Pinheiros is a big "tech" area).
I just want to point this out because this premise of more recording = more security = more behavior is not necessarily true.
I am building several small tools for myself, no real intention of sharing them yet. Some have better solutions in the market:
* Advanced tab organizer, small chrome extension to organize my bad habit of 200+ tabs, can group them into windows, search, close duplicates, search just on a specific window. Pretty fun.
* A clipboard manager, just wanted to build something in Swift for fun
I personally don't use whatsapp because I like it, but because all my contacts in my country are over there. It is officially more used than SMS here. It is not optional in my case :/
