Worth Reading: Connecting Nepal

In 1997, we finally got the Internet in Nepal. Unfortunately, it was only available in the capital, Kathmandu, which is very far from my village of Nangi. But almost immediately, I started thinking of ways we could get Nangi online. I was already familiar with the Internet from studying in the United States, and I had a lot of ideas about how being online could improve life in Nangi. —The Internet Society

The Future Internet I Want for Me, Myself and AI

Artificial Intelligence has the potential to bring immense opportunities, but it also poses challenges.

Artificial intelligence (AI) is dominating the R&D agenda of the leading Internet industry. The Silicon Valley and other startup hubs are buzzing about artificial intelligence and the issue has come at the top of policymakers’ agenda including the G20, the ITU, and the OECD, where leaders gathered this week in Paris.

The 40 hour work week

Before 1900 the average American worker worked more than 60 hours a week. A standard schedule was ten-hour days, six days a week. The only structural limits to working were lighting and religion. You stopped working when it was too dark to see or to go to church. It was exhausting. It was often fatal. —Collaborative Fund

The 40 hour work week is foremost a result of the physical limits of the human body—but we often fail to take into account the mental limits, as well. Why was working for more than 40 hours a week on a railroad dangerous? It was not just because people were physically tired, but also because they were mentally tired. The resulting discussion among coders has been rampant and widespread (see, for instance, here).

First, the focus on time and the length of the work week may be a little misdirected. We are still a world focused on physical presence as a proxy for accomplishing work. I know a lot of companies prefer to have people in the office—ironically, this is a big deal with most of the companies in the world that aim to bring networks, and network based services, to the masses.

IDG Contributor Network: Real world challenges between us and the Internet of Things

Many a blog line has been penned on the rich topic of the Internet of Things (IoT) but not much has been written about the real world challenges between our today and the many promises of the IoT tomorrow. Technology considerations can easily blind us “techies” to more mundane realities but, when you work as deeply in the Smart City space as I do, it is difficult to avoid them. In my opinion, the technology challenges surrounding the IoT are relatively small compared to the real world challenges that are perhaps not so obvious.Some say the IoT is now, but I don’t believe that! I believe we are on a journey, and the trajectory of every vertical industry to this destination will be carved somewhat uniquely and at its own necessary pace. Healthcare is often touted as a darling of the IoT, but the privacy, security and regulatory issues here might never be adequately solved in a way that will allow this sensitive data to be leveraged up significantly into any wider value creating ecosystem. The automotive and intelligent transportation verticals, on the other hand, look more promising to me in terms of fast tracking their way to the Continue reading

Worth Reading: pbgpp

pbgpp allows network operators to apply a wide range of filters, either on network layer (src IP, dst IP), but foremost BGP fields — for example, prefix, communities, or next hop. Filters are applied in two steps, improving analysis performance. Before parsing the BGP-specific fields in the captured packet, lower-layer packet header field filters (IP or MAC source or destination) are applied. Thus, we do not parse all packets, but only the matching ones. BGP-specific filters are applied subsequently after parsing. —APNIC
