Submission + - The Quantum Secret to Superconductivity (quantamagazine.org)

An anonymous reader writes: The experimental team, led by LNCMI staff scientist Cyril Proust and Louis Taillefer of the University of Sherbrooke in Canada, used their 90-tesla magnet — which creates a magnetic field nearly two million times as strong as the one enshrouding Earth — to momentarily strip away superconductivity in their cuprate sample. This revealed details of the underlying phase from which the behavior seems to arise.

With the veil lifted, the scientists discovered a sharp change in behavior at what appears to be a “quantum critical point” in cuprates, reminiscent of the freezing point of water. Theorists have long speculated that such a quantum critical point might exist, and that it could play a key role in superconductivity, said Andrey Chubukov, a condensed-matter theorist at the University of Minnesota. “One thing is to say this; another thing is to measure it,” Chubukov said.

Submission + - What Bell Labs was like c.1967 1

niittyniemi writes: There's a rather interesting photo-gallery over at The Guardian which gives an indication of what life was like at Bell Labs c.1967.

This was the year that Dennis Ritchie joined Bell Labs and went on to produce a body of work which has been pretty much unrivalled in its influence on the modern computing landscape, even some 50 years later.

What's noticeable about the pictures, is that they are of woman. I don't think this is a result of the photographer just photographing "eye candy". I think it's because he was surrounded by women, whom from his comments he very much respected and hence photographed.

In those times, wrangling with a computer was very much seen as "clerical work" and therefore the domain of woman. This can be seen as far back as Bletchley Park and before that Ada Lovelace.

Yet 50 years later, the IT industry has turned full-circle. Look at any IT company and the percentage of women doing software development or similar is woeful. Why and how has this happened? Discuss.

You could use a separate subdomain: secure.slashdot.org, just make that host default to https. But a looming problem is that browser vendors may start making non-https look bad: http://thevarguy.com/secure-cl... I suppose the inverse could be done too, default to https on the regular address and have a subdomain dedicate to non-https.

I expect to get what I pay for. If I pay for 65Mbps of bandwidth, just as I pay for Netflix to stream to 4 devices simulaneously. If I have 4 devices (2 adults + 2 kids) in my house, and each is streaming 15Mbps video, there should be enough bandwidth to satisfy all with 5Mbps left over for web browsing, email, etc. ISPs are just upset that we are relagating them to the status of a utility and envious of the profits enjoyed by the video services who CAN actually deliver what we each want, on demand.

These services are built around the idea of a normalized distribution of usage.

And they realize that as that distribution drifts over time, their lucrative business of broadcasting packages of channels, turns into managing the plumbing for their partners/competitors.
