Startup Has a New Way to Make Rare Earths and Other Metals

The ceramic material Powell showed me—which is made of zirconium oxide—replaces the carbon electrode and eliminates those emissions. Researchers have been trying to replace carbon for many years, but the molten salts have corroded the alternatives. The key advance for Infinium was developing alternative molten salts that don’t react with the zirconium oxide, so that it can last long enough to be practical.

Finding an alternative to carbon has long been the “dream” of the metals industry, says Donald Sadoway, a professor of materials science at MIT who is not involved with the company. “I believe [Infinium’s] technology is sound. It’s real,” he says. Whether the company succeeds “is all about the economics,” he says. “No one cares about the flow chart for the process. You care about the prices. If it produces a good metal at a lower cost, people will be interested.”

Instrumental Variables Methods

Estimating causal impacts is fraught with difficulty. Even randomized trials are imperfect, in part because we can seldom, if ever, conduct true experiments (though experimental design is still the gold standard of statistical research). IV is one of the more compelling quasi-experimental methods of estimating impacts, largely because the assumptions needed to justify the IV method are often more plausible than those needed to justify other methods, such as regression.

Hundreds of Cities Are Wired With Fiber—But Telecom Lobbying Keeps It Unused

Throughout the country, companies like Comcast, Time Warner Cable, CenturyLink, and Verizon have signed agreements with cities that prohibit local governments from becoming internet service providers and prohibit municipalities from selling or leasing their fiber to local startups who would compete with these huge corporations.

First patent troll ordered to pay “extraordinary case” fees

“Lumen’s motivation in this litigation was to extract a nuisance settlement from FTB on the theory that FTB would rather pay an unjustified license fee than bear the costs of the threatened expensive litigation,” Cote stated in the order she issued on Friday. “Lumen’s threats of ‘full-scale litigation,’ ‘protracted discovery,’ and a settlement demand escalator should FTB file responsive papers, were aimed at convincing FTB that a pay-off was the lesser injustice.”

TrueCrypt Website Says To Switch To BitLocker

I do not know precisely what this means, as I have no contact with the developers anymore: but this is what was agreed upon.

They should no longer be trusted, their binaries should not be executed, their site should be considered compromised, and their key should be treated as revoked. It may be that they have been approached by an aggressive intelligence agency or NSLed, but I don’t know for sure.

While the source of 7.2 does not appear to my eyes to be backdoored, other than obviously not supporting encryption anymore, I have not analysed the binary and distrust it. It shouldn’t be distributed or executed.

TrueCrypt’s formal code audit will continue as planned. Then the code will be forked, the product’s license restructured, and it will evolve. The name will be changed because the developers wish to preserve the integrity of the name they have built. They won’t allow their name to continue without them. But the world will get some future version, that runs on future operating systems, and future mass storage systems.

There will be continuity . . . as an interesting new chapter of Internet lore is born.
