The Week in Internet News: Your Doorbell is Spying on You
We’ve got our eyes on you: Ring, the Amazon-owned, IoT-powered video doorbell and security system vendor, has partnered with 400 police departments across the U.S. and is providing them with video footage, the Washington Post reports. Privacy advocates have raised concerns, saying the partnerships could subject innocent people, including those who Ring users have flagged as “suspicious,” to greater surveillance.
We’re listening, too: Meanwhile, Apple has apologized for some of its contractors listening in to recordings of customer’s interactions with the Siri digital assistant, Fox Business News says. Apple had been using the recordings for quality control, but the practice was not in line with Apple’s “high ideals,” the company said.
Also, the apps: Google has pulled a popular file-scanning app, CamSpanner, from the Google Play store, after reports that it contains malware, CNN reports. Researchers Kaspersky had found several negative reviews on the app’s profile that complained the app had the “presence of unwanted features.” The malware could show “intrusive advertising” to users.
Internet spycraft: China and other nations are using popular networking site LinkedIn to recruit spies in Western nations, the New York Times reports. One former foreign policy official in U.S. President Barack Obama’s Continue reading

2019 Chapterthon – Our Chapters, Connecting the World One Community at a Time
Each year, the Chapterthon project competition brings enthusiasm and excitement among our global community. We look forward to this time of year, when our communities mobilize and work alongside each other to achieve a common goal for the development of the Internet.
For the 2019 Chapterthon, we are delighted to announce that 34 Chapters and Special Interest Groups (SIGs) from across the globe have started implementing their work on local solutions that will bring some of the hardest-to-reach places and community segments online—connecting the unconnected.
Over the next two months, these 34 projects will:
- connect underprivileged and rural areas in Armenia, Bangladesh, Benin, Mali, and South Africa;
- build a community network in Kenya;
- establish online databases for rural farmers in Burkina Faso and Saint Vincent and the Grenadines;
- create an online audio library for people living with disabilities in northern rural Argentina;
- revolutionize a mobile network unit in Madagascar for use in the event of a natural disaster;
- educate and empower over fifty rural women on how to use the Internet during a friendly game of “Tag”;
- build an FM broadcast system in rural Ghana; preserve Indigenous culture in rural Brazil;
- sweat it out at a bootcamp in Continue reading
Tech Bytes: Applying Cloud Principles To Networking With Big Switch Networks (Sponsored)
Today's sponsored Tech Bytes explores how Big Switch Networks applies cloud design principles to data center and cloud networks. Network engineers can provide a developer-friendly environment while still enforcing policy, enabling security controls, and getting visibility into the network. Our guest is Big Switch CTO Paul Unbehagen.

Forwarding using sFlow-RT
- Without Forwarding Each sFlow agent is configured to stream sFlow telemetry to each of the analysis applications. This configuration is appropriate when a small number of applications is being used to continuously monitor performance. However, the overhead on the network and agents increases as additional analyzers are added. Often it is not possible to increase the number of analyzers since many embedded sFlow agents have limited resources and only support a small number of sFlow streams. In addition, the complexity of configuring each agent to add or remove an analysis application can be significant since agents may reside in Ethernet switches, routers, servers, hypervisors and applications on many different platforms from a variety of vendors.
- With Forwarding In this case all the agents are configured to send sFlow to a forwarding module which resends the data to the analysis applications. In this case analyzers can be added and removed simply by reconfiguring the forwarder without any changes required to the agent configurations.
