Airbnb has grown significantly over the last 3 years. To support demand, the company uses 200 Amazon Elastic Compute Cloud (Amazon EC2) instances for its application, memcache, and search servers. Within Amazon EC2, Airbnb is using Elastic Load Balancing, which automatically distributes incoming traffic between multiple Amazon EC2 instances. To easily process and analyze 50 Gigabytes of data daily, Airbnb uses Amazon Elastic MapReduce (Amazon EMR). Airbnb is also using Amazon Simple Storage Service (Amazon S3) to house backups and static files, including 10 terabytes of user pictures. To monitor all of its server resources, Airbnb uses Amazon CloudWatch, which allows the company to easily supervise all of its Amazon EC2 assets through the AWS Management Console, Command Line Tools, or a Web services API.

American Airlines' wastewater treatment plant recycles water used at the base to wash aircraft, process rinse water tanks, and irrigate landscape. That alone has saved almost $1 million since 2002. In addition to that, American Airlines has also won the award for the reduction of hazardous waste that saved them $229,000 after a $2,000 investment. A bar code system is used to track hazardous waste. It has led to reduction of waste by 50 percent since 2000.[80]

One year later, there were 15 people working from Chesky and Gebbia's loft apartment on Rausch Street in San Francisco. To make room for employees, Brian Chesky gave up his bedroom and lived at lodging booked via the Airbnb service until the company moved into its first office space.[32][18] In April 2009, the company received $600,000 in seed money from Sequoia Capital[18] and, in November 2010, raised $7.2 million in financing from Greylock Partners and, again, from Sequoia Capital, in a Series A round, then announcing that out of 700,000 nights booked, 80% had occurred in the previous six months.[33]

TSA Plans to Use More Biometrics at Airport Security Checkpoints: This may creep out some passengers, but it’s probably the right move. Facial scans don’t have a 100 percent success rate, but neither do humans. And facial scans are probably faster than today’s process, in which humans must check a face against an ID card or passport. Alan Levin of Bloomberg explains what TSA plans.
As of January 2018, the airline has had almost sixty aircraft hull losses due to all causes since the crash of an American Airways Ford 5-AT-C Trimotor in August 1931.[81][82] Of these most were propeller driven aircraft, including three Lockheed L-188 Electra turboprop aircraft (of which one, the crash in 1959 of Flight 320, resulted in fatalities).[82] Seventeen jet aircraft have been written off due to crashes – including Flight 587 in 2001, Flight 965 in 1995, Flight 191 in 1979, Flight 1 in 1962 and two aircraft destroyed in the September 11 attacks – and other accidents (such as the Flight 383 engine failure and fire in 2016); two of these were training flights in which only the crew were killed and six resulted in no fatalities.[82] Another four jet aircraft have been written off due to incidents while they were parked between flights or while undergoing maintenance.[82]

Instead of relying on individual atoms, we started considering our components as elements of a living organism. They have a function and personality, are defined by a set of properties, can co-exists with others and can evolve independently. A unified design language should not just be a set of static rules and individual atoms, but an evolving ecosystem.
