Measuring and Reducing the Environmental Impact of Software
Software applications often manage big amounts of data; most of them are internet-based applications, and incorporate artificial intelligence. According to Coral Calero, these three aspects improve the capabilities and functionalities provided by software but they have also increased the amount of energy needed. We need to measure energy consumption of software to control its environmental impact.

How Testing in the Metaverse Looks
The "metaverse" typically refers to a collective virtual shared space that is created by the convergence of a virtually enhanced physical reality and a persistent virtual reality. According to Jonathon Wright, testing requires a mix of manual testing, automated testing, user testing, emulators, and simulators. Real-world testing environments are used to cover as many scenarios as possible.

How to Do Sustainable Software Development
Software sustainability includes computing for environmental purposes and using resources appropriately. According to Coral Calero, software engineers need a holistic way of looking at software and should be aware of the environmental impact of software. Several tools and frameworks are available for software engineers to do sustainable software development.

Sustainable Internet: Reducing the Environmental Impact
To be sustainable, the internet needs to assess, mitigate, and live up to its responsibilities for a healthy environment. By understanding the environmental impact, we can point to avenues where progress is possible and identify aspects of our digital infrastructures that come with unintended consequences that are too severe to look the other way.

Scaling Global Traffic at Dropbox with Edge Locations and GSLB
The Dropbox engineering team shared their experience of architecting and scaling their global network of edge locations. Located around the globe, these run a custom stack of nginx and IPVS and connect to the Dropbox backend servers over their backbone network. A combination of GeoDNS and BGP Anycast ensures availability and low latency for end users.

Digital Disruption via Space: High-Speed Internet Access through Satellites
Satellites are enabling high speed access to the internet in rural areas, on airplanes, and for internet service providers to the core network. Space technology innovations like electric propulsion, digitalization revolutionize telecommunications and new entrants like SpaceX are forcing launch costs down. These developments will enable new services and lower the costs of existing ones.

America runs out of IPv4 Addresses as IPv6 Usage Rises
ARIN, the resource registry that hands out allocations for IPv4 addresses, has announced that it has no more IPv4 addresses to give out. Although this doesn't mean no more IPv4 addresses will be allocated, it has brought to an end the question of when such addresses will run out. Meanwhile, IPv6 usage continues to climb with the release of iOS 9.
