Airbnb hosts offer free housing to evacuees displaced by California wildfires

With California’s recent cluster of devastating wildfires destroying homes and claiming lives, Airbnb is offering some shelter to displaced residents in its home state. This week, the company added free housing listings to serve evacuees affected by the Hill and Woolsey Fires outside Los Angeles and the Camp Fire in northern California.

The free Airbnb housing is currently available through November 29, 2018 for both displaced residents and relief workers helping out with recovery. The Camp Fire area shows as many as 700 participating homes in the area and the Hill and Woolsey fire areas show more than 1,400.

The California fires aren’t the first disaster relief housing that Airbnb has coordinated. The company has a disaster relief hub where it surfaces current disasters in which people might be in need of housing. Right now, Airbnb is also coordinating free housing through hosts near Marseille after a building collapsed in the French city earlier this month. Two months ago, Airbnb encouraged hosts to sign up to offer their homes as residents evacuated before Hurricane Florence.

To sign up as an emergency housing host in one of those areas, you can follow the instructions behind the button to “sign up your home” after clicking through to your area from Airbnb’s main emergency housing portal.

RFID stickers could signal contaminated food

If a food item isn’t safe to eat, it’s best to find that out before someone eats it. But manual testing of every jar and bottle isn’t possible, even when a threat, like the recent baby food scare, is known. MIT researchers have found a way to check many items instantly, non-invasively and from a distance — using the RFID tags many products already have.

RFID, or radio frequency identification, uses a tiny antenna embedded in a sticker or label that’s activated and powered by radio waves at a very specific frequency. When a transceiver sends out a 950Mhz signal, the RFID tag wakes up and re-transmits a slightly different signal identifying itself. Products that announce themselves? Convenient for doing inventory!

What the researchers found was that this return signal, outside the actual information-bearing part, can be affected by the actual contents of the product, since the radio waves have to pass through them. Consequently, a jar full of pasta sauce and one full of olives would produce different signal profiles — as would an untouched jar of baby food compared with one contaminated with melamine.

“It’s almost as if we have transformed cheap RFIDs into tiny radio frequency spectroscopes,” said Fadel Adib, co-author of the paper describing the new system, in an MIT news release.

The problem is that these differences can be very minor and it’s not like they’ve been documented anywhere — this is the first time anyone’s tried this. So naturally, the team turned to machine learning. They trained up a model that can tell with confidence what a signal profile corresponds to, with the minor variations that come from, say, slight differences in orientation or glass width.

Right now the system, which they call RFIQ, can tell the difference between pure and melamine-contaminated baby formula, and between various adulterations of pure ethyl alcohol. That’s pretty much everything on my shopping list so I’m set, but obviously the team would like to have it apply to many more products. Now that the method has been shown to work, that’s the plan.

The task will only get harder, as things like environmental variables (shelves) and other wireless interference add to the problem. But machine learning algorithms are good at plucking signal out of the noise, so with luck the technique will work without too much trouble.

You can read the full paper documenting the RFIQ system here (PDF).

The Correspondent launches campaign to bring its ad-free journalism to the US

De Correspondent, a Dutch news organization aiming to “unbreak the news,” is planning to launch in the United States next year as The Correspondent. To fund its efforts, it’s hoping to raise $2.5 million from future readers.

Co-founder and CEO Ernst Pfauth (a former tech journalist who previously served as editor in chief at The Next Web) said this campaign is meant to test the waters of whether U.S. readers are interested in The Correspondent’s journalism. If it raises the money, it will launch in the U.S. next spring. If it doesn’t, it will reconsider those plans.

“We want there to be a critical mass that supports this,” Pfauth said. “We don’t want to launch, then see if enough people are interested.”

What the company has developed in the Netherlands, and what it’s hoping to replicate in the U.S., is a news organization with a direct connection to readers. For one thing, that means foregoing any ad revenue and relying entirely on readers for support. (Hence the crowdfunding campaign, where you can sign up by paying any amount you want.) It has a paywall, but any member can circumvent it and promote stories they think are important by sharing the individual links.

For another, it means treating readers as a key source for stories. In Pfauth’s view, by signing up as a “founding member,” you’re not so simply paying for a subscription, “You’re joining a cause. You not just giving us your money — though the money is essential — but you’re sharing your knowledge and spreading articles.”

The Correspondent

If that sounds a bit touchy-feely, here’s a concrete example: Last year, the organization broke the news that a videotape and related documents showed that Shell had detailed knowledge about the dangers of climate change as far back as 1991. And apparently it obtained the crucial material from a reader.

Pfauth said that in most cases, reporters at The Correspondent will share their story ideas with members as soon as they start working on it, which allows readers to share their perspectives as the story develops. That can mean talking to doctors about hospital bureaucracy, or interviewing refugees about their experiences. It also means that The Correspondent encourages its journalists to spend 30 to 50 percent of their time going through the comments section (which it calls the “contributions” section), where only members can post.

Pfauth argued that all of this is crucial for breaking out of the limited perspective of so many news stories, where journalists “only talk to people who get paid to talk to the press.” That description struck close to home — I’m someone who spends a lot of their time dealing with PR pros who, yes, get paid to talk to me, or to entrepreneurs who are trying to convince me to write about their companies.

So how do you get people to share their perspective in a less self-interested (or, in the case of comments, less rant-y) way? Pfauth pointed to tactics like making sure to verify the identity of sources and asking “really specific questions.” But he also said, “Most people are idealistic about the thing they really care about. They want the information to be good.”

“You are going to find examples of other newspapers who have done things like this, but it’s always incidental, it’s not routine,” he added. “In our organization, we have this systematic approach to every story that we cover.”

This strategy makes it harder to quickly cover breaking news, but in fact, Pfauth said that’s quite intentional.

“We tell our correspondents, please ignore the news — the news is about incidents,” he said. “Focus on the topics in your beat that are really changing our society.”

As part of this campaign, The Correspondent has also enlisted a number of high-profile “ambassadors” who support its mission. Those ambassadors include FiveThirtyEight’s Nate Silver, Wikimedia’s Jimmy Wales, director Judd Apatow, journalist, musician Roseanne Cash, journalist and investor Om Malik and others.
