- 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.”
ENTRIES TAGGED "Internet of Things"
What “design beyond the screen” means for the industrial Internet.
Design beyond the screen is a much broader and more transformative concept than just that, though: it encompasses changes in the relationships between humans and machines and between machines and other machines. Good design beyond the screen makes interaction more fluid and elevates both people and machines to do their best work. The impact of good design beyond the screen could be huge, and could extend well beyond consumer electronics into heavy industry and infrastructure. Read more…
A suitable network topology for building automation.
Editor’s note: 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.
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.

Data from the Internet of Things makes an integrated data strategy vital.
The Internet of Things (IoT) is more than a network of smart toasters, refrigerators, and thermostats. For the moment, though, domestic appliances are the most visible aspect of the IoT. But they represent merely the tip of a very large and mostly invisible iceberg.
IDC predicts by the end of 2020, the IoT will encompass 212 billion “things,” including hardware we tend not to think about: compressors, pumps, generators, turbines, blowers, rotary kilns, oil-drilling equipment, conveyer belts, diesel locomotives, and medical imaging scanners, to name a few. Sensors embedded in such machines and devices use the IoT to transmit data on such metrics as vibration, temperature, humidity, wind speed, location, fuel consumption, radiation levels, and hundreds of other variables.

When to use a star network.
This article is part of a series exploring the role of networking in the Internet of Things.
In my previous post we evaluated a point-to-point networking technology, specifically Bluetooth, to determine its applicability to our building monitoring and energy application. In this post, we will evaluate the use of a star networking technology to meet our application needs.
A star network consists of one central hub that establishes a point-to-point network connection with all other nodes in the network (e.g. sensor nodes). This central hub acts as a common connection point for all nodes in the network. All peripheral nodes may therefore communicate with all others by transmitting to, and receiving from, the central hub only.
Today, Wi-Fi is by far the most commonly used wireless star topology. It is deployed widely throughout many environments, providing near ubiquitous internet access in facilities such as schools, campuses, office buildings, lodging, residential homes and so on. The term Wi-Fi is not a standard, but a term trademarked by The Wi-Fi Alliance and covering a number of IEEE 802.11 standards along with details of implementation.
As in past posts, let’s take a closer look at the technology and evaluate WI-Fi’s capabilities against the nine key application attributes that characterized our building monitoring and energy management application.
