At Slate, David Auerbach reports on Thursday's hearing concerning the healthcare.gov debacle. It was "a spectacle of tech illiteracy and buck-passing", he says, which may not elicit much surprise around here. He is particularly scornful of the contractors' obsession with checking off milestones rather than with delivering something that works, their willingness to call something 'done' before having tested it, and their apparent obliviousness to how incompetent this shows them to be.

A study presented at the American Sociological Association's annual meeting suggests that simply comparing the frequency with which the candidates' names are mentioned in tweets can predict the result of elections almost as well as conventional polls, even without considering the sentiment (for or against the named candidate) of the messages. Furthermore, the correlation seems strongest in close elections.
Additional commentary can be found at the Wall Street Journal and from Indiana University.

Thorium has attracted interest as a potentially safer fuel for nuclear power generation. In part, this has been because of the absence of a route to nuclear weapons, but a group of British scientists have identified a path that leads to uranium-233 via protactinium-233 from irradiated thorium. The protactinium separation could possibly be done with standard lab equipment, which would allow it to be done covertly, and deliver the minimum of U233 required for a weapon in less than a year.

A couple of months ago, the New York Times published political scientist Andrew Hacker's opinion that teaching algebra is harmful. Today, it has followed up with an article that is clearly intended to indicate the usefulness of basic mathematics by suggesting useful exercises in a variety of 'real-world' topics. While the starter questions in each topic involve formula evaluation rather than symbolic manipulation, the follow-up questions invite readers to delve more deeply.
The value of mathematics education has been a recurring issue in Slashdot.

Andrew Hacker, a professor of Political Science at the City University of New York and author of 'Higher Education? How Colleges Are Wasting Our Money and Failing Our Kids — and What We Can Do About It', attempts to answer this question in the negative in today's New York Times Sunday Review [registration may be required].
His primary claim is that mathematics requirements are prematurely and unreasonably limiting the level of education available to otherwise capable students .

At Boing Boing, Rob Beschizza reports that, in an act of delicious irony, Swiss ISP Ort Cloud [sic] has acquired Righthaven's domain name and has relaunched Righthaven.com as a web hosting service diametrically opposed to the practices of its original owner, a notorious but ultimately unsuccessful copyright troll. The new owners, in partnership with first amendment lawyer Marc Randazza (who was instrumental in the original Rigthhaven's demise), promise "infrajuridsictional infrastructure" — uptime that would require international cooperation to bring down. "Frivolous plaintiffs will find little comfort here" says Ort Cloud's Stefan Thalberg.
The domain name became available in a court-ordered auction of Righthaven LLC's assets, to pay its creditors.

The New York Times summarizes a paper published online by Science:
Taking a test is not just a passive mechanism for assessing how much people know, according to new research. It actually helps people learn, and it works better than a number of other studying techniques.
