Coders from Colombia give people a lifeline in crisis

One of the first challenges of a severe weather event is often a loss of electricity and communication systems. Damaged infrastructure cannot be repaired until it is safe to do so, leaving people in the dark and out of reach for emergency response services. Finding a way to bring people online to send out distress signals could help locate injured people and save lives. Read more.
