- Inside bit.ly’s Distributed Systems — this is a 101 for modern web distributed systems design.
- Patent Trolls are Now 67% of New Patent Lawsuits in USA (WaPo) — data from PwC.
- Intel Made Half a Billion from Internet of Things Last Year (Quartz) — half a billion here, half a billion there, pretty soon it adds up to real money.
- Google’s Project Zero (Wired) — G pays a team to attack common software and report the bugs to the manufacturer. Interesting hypothesis about how the numbers inbalance between Every Russian 14 Year Old and this small team doesn’t matter: modern hacker exploits often chain together a series of hackable flaws to defeat a computer’s defenses. Kill one of those bugs and the entire exploit fails. That means Project Zero may be able to nix entire collections of exploits by finding and patching flaws in a small part of an operating system, like the “sandbox” that’s meant to limit an application’s access to the rest of the computer. ”On certain attack surfaces, we’re optimistic we can fix the bugs faster than they’re being introduced,” Hawkes says. “If you funnel your research into these limited areas, you increase the chances of bug collisions.”

Government sensor networks can streamline processes, cut labor costs, and improve services.
It’s not news to anyone who works in government that we live in a time of ever-tighter budgets and ever-increasing needs. The 2013 federal shutdown only highlighted this precarious situation: government finds it increasingly difficult to summon the resources and manpower needed to meet its current responsibilities, yet faces new ones after each Congressional session.
Sensor networks are an important emerging technology that some areas of government already are implementing to bridge the widening gap between the demand to reduce costs and the demand to improve services. The Department of Defense, for instance, uses RFID chips to monitor its supply chain more accurately, while the U.S. Geological Survey employs sensors to remotely monitor the bacterial levels of rivers and lakes in real time. Additionally, the General Services Administration has begun using sensors to measure and verify the energy efficiency of “green” buildings (PDF), and the Department of Transportation relies on sensors to monitor traffic and control traffic signals and roadways. All of which is productive, but more needs to be done. Read more…
A Suitable Network Topology for Building Automation
This article is part of a series exploring the role of networking in the Internet of Things.
Today we are going to consider the attributes of wireless mesh networking, particularly in the context of our building monitoring and energy application.
A host of new mesh networking technologies came upon the scene in the mid-2000s through start-up ventures such as Millennial Net, Ember, Dust Networks, and others. The mesh network topology is ideally suited to provide broad area coverage for low-power, low-data rate applications found in application areas like industrial automation, home and commercial building automation, medical monitoring, and agriculture.
Business users are becoming more comfortable with graph analytics.
The rise of sensors and connected devices will lead to applications that draw from network/graph data management and analytics. As the number of devices surpasses the number of people — Cisco estimates 50 billion connected devices by 2020 — one can imagine applications that depend on data stored in graphs with many more nodes and edges than the ones currently maintained by social media companies.
This means that researchers and companies will need to produce real-time tools and techniques that scale to much larger graphs (measured in terms of nodes & edges). I previously listed tools for tapping into graph data, and I continue to track improvements in accessibility, scalability, and performance. For example, at the just-concluded Spark Summit, it was apparent that GraphX remains a high-priority project within the Spark1 ecosystem.
The convergence of six factors is creating a climate for mainstream IoT adoption.
The term “Internet of Things” isn’t new. Some say it was coined in 1999 by Kevin Ashton to describe a world where “things,” which can be devices or sensors, are both smart and connected — meaning they have the ability to collect and share data. The data coming from those devices and/or sensors then becomes a kind of currency, which can be combined and analyzed with other types of data to uncover insights that were, until recently, out of reach.
Although technology experts have quoted Moore’s Law, anticipating for decades the evolution of devices with embedded microchips, the proliferation of connected industry devices, and the rise of machine-to-machine communications, today we are seeing that the Internet of Things is at an inflection point.
