In Brazil we have this http://www.cataki.org/ (pt-br) an app that connects waste pickers to people who want to dispose reusable or recyclable materials.
According to this site 800,000 waste pickers in the country and 300 registered on the service.
FWIW:
"The name Postgres is an accepted alias for the PostgreSQL project. However it is an alias or nickname and is not the official name of the project."
I live in a neighbor city of São Paulo city, Brazil.
I have a 2hrs+ commute , 4hrs+ a day. I take a train (~1hr), a subway(~30min) and another train(~30min), I work next to train station.
The train use to be crowded with no seats to take. I try to make the travel as pleasant and productive as I can, I read news and books - almost finishing Uncle Bob's "Clean Code" -, listen to podcasts and music, watch movies etc..
I am SW developer in a big electronics vendor, we are not allowed to work from home, I lived some time in São Paulo during graduation and working full time, but it was expensive and lonely for me, I live with my parents and near of all my relatives now, but I am thinking to move back soon.
We have no many jobs in my city, so even people that no have skilled jobs use to have long commutes.
It works for me for Chromium on Ubuntu.
