Jonathan Zdziarski's HOPE X talk, Identifying Backdoors, Attack Points, and Surveillance Mechanisms in iOS Devices, suggests that hundreds of millions of Iphone and Ipad devices ship from Apple with intentional back-doors that can be exploited by law enforcement, identity thieves, spies, and employers.

Raffi Krikorian is a smart engineer and technical manager; I've know him for decades, but didn't realize that he was currently Vice President for Platform Engineering at Twitter. This interview with him at InfoQ gives a really fascinating flavor for how Twitter's reliability engineering is baked in at the systems level:

Here's a very short and snappy explanation for why so much of the UK's government IT infrastructure is so fantastically, awfully bad: it's an RFP from a Northern Irish government business development fund for a "Content Management System to manage all Invest NI websites and intranets." Here's how they express their priorities:
The most economically advantageous tender in terms of
1. Price. Weighting 95
2. Quality. Weighting 5
This is for a 523 000 GBP contract, by the way.
Invest NI wishes to appoint a suitably qualified service provider to install, configure, maintain and support a Content Management System to manage all Invest NI websites and intranets... (Thanks, Angie!)
As someone who's spent a bit of time working in corporate IT management, I had to laugh and wince at Simon Wardley spot-on chart of the enterprise IT adoption cycle. It's so sadly accurate, including the steepness of the curve between "Oh fuck" and full adoption (which is why so many vendors hammer away at IT departments with technologies that IT has already rejected).
The US Office of the National Coordinator for Health Information Technology (ONC) is hosting a Healthy New Year Video Challenge with cash prizes of up to $2,000. They're soliciting short videos with the theme of a New Year’s resolution for improving your health or the health of a loved one, through technology.
"Videos must show how you will use information technology to achieve your resolution and how you plan to maintain it," according to the contest website. The sort of topics one might address (one per video) include obtaining your health records from your doctors and learning how to read and understand their contents, finding online support communities for a specific illness, or direct health improvement actions like using an electronic pedometer to track physical activity, or an iPhone app to count calories or monitor sleep cycles.
Server farms generate so much heat that they have to run air conditioning year round. That requires energy, which costs money and tends to mean burning more fossil fuels. Meanwhile, in winter, a lot of houses are cold. The people who live there have to turn on the heat, which costs money and tends to mean burning more fossil fuels.
So here's an idea: Why not distribute the hardware from a server farm, putting heat-producing equipment in houses that actually need the heat?
If a home has a broadband Internet connection, it can serve as a micro data center. One, two or three cabinets filled with servers could be installed where the furnace sits and connected with the existing circulation fan and ductwork. Each cabinet could have slots for, say, 40 motherboards — each one counting as a server. In the coldest climate, about 110 motherboards could keep a home as toasty as a conventional furnace does.
The rest of the year, the servers would still run, but the heat generated would be vented to the outside, as harmless as a clothes dryer’s. The researchers suggest that only if the local temperature reached 95 degrees or above would the machines need to be shut down to avoid overheating. (Of course, adding a new outside vent on the side of the house could give some homeowners pause.)
According to the researchers’ calculations, a conventional data center must invest about $400 a year to run each server, or about $16,000 for a cabinet filled with 40 of them. (This includes the costs of building a bricks-and-mortar center and of cooling the machines.)
Having homes host the machines could reduce the need for a company to build new data centers. And the company’s cost to operate the same cabinet in a home would be less than $3,600 a year — and leave a smaller carbon footprint, too. The company’s data center could thus cover the homeowner’s electricity costs for the servers and still come out way ahead financially.
It could certainly produce some logistical problems with security, but it's an intriguing idea, and a great example of how we can get the energy services we want for much less energy use. The researchers who proposed it, from Microsoft and the University of Virginia, call it a "data furnace." It'll be interesting to see where the idea goes from here.
