## The complexity of the IoT requires experience design solutions

### Claire Rowland on interoperability, networks, and latency.

The Internet of Things (IoT) is challenging designers to rethink their craft. I recently sat down with Claire Rowland, independent designer and author of the forthcoming book Designing Connected Products to talk about the changing design landscape.

During our interview, Rowland brought up three points that resonated with me.

## Interoperability and the Internet of Things

This is an IoT issue that affects everyone — engineers, designers, and consumers alike. Rowland recalled a fitting quote she’d once heard to describe the standards landscape: “Standards are like toothbrushes, everyone knows you need one, but nobody wants to use anybody else’s.”

Designers, like everyone else involved with the Internet of Things, will need equal amounts of patience and agility as the standards issue works itself out. Read more…

## Smarter buildings through data tracking

### Buildings are ready to be smart — we just need to collect and monitor the data.

Buildings, like people, can benefit from lessons built up over time. Just as Amazon.com recommends books based on purchasing patterns or doctors recommend behavior change based on what they’ve learned by tracking thousands of people, a service such as Clockworks from KGS Buildings can figure out that a boiler is about to fail based on patterns built up through decades of data.

I had the chance to be enlightened about intelligent buildings through a conversation with Nicholas Gayeski, cofounder of KGS Buildings, and Mark Pacelle, an engineer with experience in building controls who has written for O’Reilly about the Internet of Things. Read more…

## 8 key attributes of Bluetooth networking

### Bluetooth networking within the Internet of Things

Previously, we set out to choose the wireless technology standard that best fits the needs of our hypothetical building monitoring and energy application. Going forward, we will look at candidate technologies within all three networking topologies discussed earlier: point-to-point, star, and mesh. We’ll start with Bluetooth, the focus of this post.

Bluetooth is the most common wireless point-to-point networking standard, designed for exchanging data over short distances. It was developed to replace the cables connecting portable and/or fixed devices.

Today, Bluetooth is well suited for relatively simple applications where two devices need to connect with minimal configuration setup, like a button press, as in a cell phone headset. The technology is used to transfer information between two devices that are near each other in low-bandwidth situations such as with tablets, media players, robotics systems, handheld and console gaming equipment, and some high-definition headsets, modems, and watches.

When considering Bluetooth for use in our building application, we must consider the capabilities of the technology and compare these capabilities to the nine application attributes outlined in my previous post. Let’s take a closer look at Bluetooth across these eight key attributes.

## Health IT is a growth area for programmers

### New report covers areas of innovation and their difficulties

O’Reilly recently released a report I wrote called The Information Technology Fix for Health: Barriers and Pathways to the Use of Information Technology for Better Health Care. Along with our book Hacking Healthcare, I hope this report helps programmers who are curious about Health IT see what they need to learn and what they in turn can contribute to the field.

Computers in health are a potentially lucrative domain, to be sure, given a health care system through which $2.8 trillion, or$8.915 per person, passes through each year in the US alone. Interest by venture capitalists ebbs and flows, but the impetus to creative technological hacking is strong, as shown by the large number of challenges run by governments, pharmaceutical companies, insurers, and others.

Some things you should consider doing include:

Join open source projects

Numerous projects to collect and process health data are being conducted as free software; find one that raises your heartbeat and contribute. For instance, the most respected health care system in the country, VistA from the Department of Veterans Affairs, has new leadership in OSEHRA, which is trying to create a community of vendors and volunteers. You don’t need to understand the oddities of the MUMPS language on which VistA is based to contribute, although I believe some knowledge of the underlying database would be useful. But there are plenty of other projects too, such as the OpenMRS electronic record system and the projects that cooperate under the aegis of Open Health Tools

## Business models that make the Internet of Things feasible

### The bid for widespread home use may drive technical improvements.

For some people, it’s too early to plan mass consumerization of the Internet of Things. Developers are contentedly tinkering with Arduinos and clip cables, demonstrating cool one-off applications. We know that home automation can save energy, keep the elderly and disabled independent, and make life better for a lot of people. But no one seems sure how to realize this goal, outside of security systems and a few high-end items for luxury markets (like the Nest devices, now being integrated into Google’s grand plan).

But what if the willful creation of a mass consumer market could make the technology even better? Perhaps the Internet of Things needs a consumer focus to achieve its potential. This view was illuminated for me through a couple recent talks with Mike Harris, CEO of the home automation software platform Zonoff.

## 3 topologies driving IoT networking standards

### The importance of network architecture on the Internet of Things

There are a lot of moving parts in the networking for the Internet of Things; a lot to sort out between WiFi, WiFi LP, Bluetooth, Bluetooth LE, Zigbee, Z-Wave, EnOcean and others. Some standards are governed by open, independent standards bodies, while others are developed by a single company and are being positioned as defacto standards. Some are well established, others are in the early adoption stage. All were initially developed to meet unique application-specific requirements such as range, power consumption, bandwidth, and scalability. Although these are familiar issues, they take on a new urgency in IoT networks.

To begin establishing the right networking technology for your application, it is important to first understand the network architecture, or the network topology, that is supported by each technology standard. The networking standards being used today in IoT can be categorized into three basic network topologies; point-to-point, star, and mesh. Read more…

## Internet of Things in celebration and provocation at MIT

### IoTFest reveals exemplary applications as well as challenges

Last Saturday’s IoT Festival at MIT became a meeting ground for people connecting the physical world. Embedded systems developers, security experts, data scientists, and artists all joined in this event. Although it was called a festival, it had a typical conference format with speakers, slides, and question periods. Hallway discussions were intense.

However you define the Internet of Things (O’Reilly has its own take on it, in our Solid blog site and conference), a lot stands in the way of its promise. And these hurdles are more social than technical.

## Hurdles to the Internet of Things prove more social than technical

### MIT's IoTFest reveals the IoT poses as much challenge as it does promise.

Last Saturday’s IoT Festival at MIT became a meeting-ground for people connecting the physical world. Embedded systems developers, security experts, data scientists, and artists all joined in this event. Although it was called a festival, it had a typical conference format with speakers, slides, and question periods. Hallway discussions were intense.

However you define the Internet of Things (O’Reilly has its own take on it, in our Solid blog site and conference), a lot stands in the way of its promise. And these hurdles are more social than technical.

Some of the social discussion we have to have before we get the Internet of Things rolling are:

• What effects will all this data collection, and the injection of intelligence into devices, have on privacy and personal autonomy? And how much of these precious values are we willing to risk to reap the IoT’s potential for improving life, saving resources, and lowering costs?

## MathML forges on

### The standard for mathematical content in publishing work flows, technical writing, and math software

20 years into the web, math and science are still second class citizens on the web. While MathML is part of HTML 5, its adoption has seen ups and downs but if you look closely you can see there is more light than shadow and a great opportunity to revolutionize educational, scientific and technical communication.

Somebody once compared the first 20 years of the web to the first 100 years of the printing press. It has become my favorite perspective when thinking about web standards, the web platform and in particular browser development. 100 years after Gutenberg the novel had yet to be invented, typesetting quality was crude at best and the main products were illegally copied pamphlets. Still, the printing press had revolutionized communication and enabled social change on a massive scale.

In the near future, all our current web technology will look like Gutenberg’s original press sitting next to an offset digital printing machine.

With faster and faster release cycles it is sometimes hard to keep in mind what is important in the long run—enabling and revolutionizing human communication.

Since I joined the MathJax team in 2012, I have gained many new perspectives on MathML, the web standard for display of mathematical content, and its role in making scientific content a first class citizen on the web. But it is rather useless to talk about MathML’s potential without knowing about the state of MathML on the web. So let’s tackle that in this post.

## Security After the Death of Trust

### Not just paying attention, but starting over

Security has to reboot. What has passed for strong security until now is going to be considered only casual security going forward. As I put it last week, the damage that has become visible over the past few months means that “we need to start planning for a computing world with minimal trust.”

So what are our options? I’m not sure if this ordering goes precisely from worst to best, but today this order seems sensible.

Stay the Course

This situation may not be that bad, right?
