When overwhelmed by the stupidity, ignorance and despair around me, I like going back to these just to regain some hope in humanity:
5-minute video of the beginning of Hackerspace and Makerspace movement in the Middle East, narrated by awesome Bilal Ghalib - sudo make hope. The whole movement inspires me with their irresistibility - even after having their hackerspace bulldozed by the government Tarek Omar and other people continue to educate and encourage people all around Egypt.
20-minute video of Mitch Altman sharing his stories and ideas from hackerspaces in Germany and USA. Spiritual father of many communities around the world doesn't want to be a bearded sage in an ivory tower - he's out there, hacking and having fun with other people!
During the Ebola epidemic in 2014 Sierra Leone was crippled as a country. There was no management system existing to coordinate all the doctors and international aid workers, the salaries haven't been paid for months, the riots were just starting. Several self-taught hackers took a little over a month to develop an open ERP system and a mobile banking platform which saved the country.
Sheer wonder of the world
A beautiful spiritual description of Earth and our civilization by Carl Sagan from his book of the same title.
Very transhumanist, optimistic short on the world around us.
