The startup Kitchen United calls itself the future of takeout and delivery, with stripped-down locations in Chicago; Austin; Pasadena, California; and Scottsdale, Arizona. It had hoped to open a shop in Berkeley, California. But CEO Jim Collins says city officials there wanted the company to create a more elaborate “front of house” setup akin to a typical restaurant. Kitchen United balked.

Kitchen United is a virtual kitchen, playing host to 10 or so already-established restaurants in each facility. The businesses save money on rent and labor by operating from something like a WeWork for restaurants. Efficiency is the byword here. Customers generally use apps to order—maybe from more than one restaurant at the same time, if one person wants sushi and another wants a falafel sandwich. Each location is designed for app-based takeout and delivery, with space for delivery people to park their cars or bikes and wait for orders.

Some virtual kitchen companies, like Reef Technology or Travis Kalanick’s CloudKitchens, sometimes build their facilities in industrial areas or abandoned parking lots, where rent is cheaper and room is abundant. But Collins and his colleagues don’t like that strategy. Instead, they seek real estate closer to the diners they want to serve. “I don’t want to be on Main and Main,” Collins says. “But I do want to be within a couple of blocks of Main and Main.”

Kitchen United employs greeters and places kiosks near the entrance, in case a confused diner or delivery person wanders in and wants food. But Berekley, Collins said, hoped for more places for customers to linger. “They were trying to improve the feel of the area we were in, and they saw us as a path to get that done,” he says. (City officials did not respond to questions.) So for now, that project isn’t moving forward.

During a pandemic, takeout is hot and so are ghost kitchens. Research completed last year by the consultancy Foodservice IP counted 119 ghost kitchens around the country, run by companies like Kitchen United, Reef, Zuul Kitchens, Katopi, or CloudKitchens. But with traditional restaurants closed or limited to takeout in many places, Tim Powell, the managing principal of Foodservice IP, projects the number of ghost kitchens will double over the next 12 months.

The recommendations app Yelp says that the owners of 15,770 food businesses reported closing permanently between mid-March and mid-June, more than any other business sector tracked by the app. Cloud kitchens hope to fill the gap, and perhaps, expand the pie.

“We’re going to start to see a lot of creative opportunities with a lot of especially second-generation restaurants that unfortunately aren’t going to make it through this,” says Corey Manicone, the cofounder and CEO of Zuul Kitchens. But ghost kitchens generally won’t replace restaurants in the same location. Zuul’s first, which opened May 2019 in New York, hosts nine takeout-only restaurants in 9,000 square feet in a quieter part of SoHo. He’s heard talk of restaurants abandoning brick-and-mortar sites for ghost kitchens, but he’s not sure his business will box out dine-in restaurants. He calls it a “personal mission” to “take a very archaic and challenging industry and bring it into the new era. I never thought it would be accelerated as much as it has been in a Covid world.”

For restaurateurs, delivery feels different. Here’s what Santiago Rodriguez misses most: conversations with regulars and knowing what they’d eat before they ordered; repeat customers who bring in new diners and tip them off about favorites, like they’re sharing a secret; telling people about the new art on display; the folks who come for lunch and stay for hours. But in May 2019, after 20 years in business, Rodriguez’s Belgian-style restaurant Frjtz stopped serving food out of its storefront in San Francisco’s Mission neighborhood. The rent had nearly doubled, and other expenses were climbing.

President Trump’s executive orders seeking to ban China-owned WeChat and TikTok in the US had been signaled for months. When Secretary of State Mike Pompeo told Fox News in early July that the US was “looking at” clamping down on the social media apps, the writing was on the wall. But when Trump followed through with the announcement on Thursday it was still a shock to Chinese living in the United States, including many who are American citizens. The assault on WeChat was particularly stunning and perplexing.

TikTok is mainly used by millennials and gen Zers of all kinds to show off their dance moves, cakes, pranks, or makeup techniques, and it also may have gotten under Trump’s skin when some of his young opponents used it to try to sabotage his last (less-than) big rally in Tulsa in June.

WeChat, on the other hand, is mainly favored in the US by most of the country’s more than 3 million Chinese immigrants of all ages, both to communicate with other Chinese in the country and with people back home in China, where it is ubiquitous and has most of its billion-strong user base. In China, WeChat is about as powerful as Twitter, WhatsApp, and Facebook are combined in the US.

In recent years, WeChat has been partially hijacked by conservative thinkers in the Chinese community. Indeed, it was the birthplace of Chinese Trumpism in 2016, and it’s where many of the president’s Chinese supporters are mobilizing for his re-election. With the election less than 90 days away and (if the executive order is actually executed) as WeChat might be paralyzed by late September, some Chinese Trump supporters are wondering if Trump realizes the implications of what he’s doing.

To be sure, the real impact of the executive orders is still subject to the government’s interpretation. The orders declare that “any transaction” related to WeChat, TikTok, or their parent companies—Tencent and ByteDance, respectively—be prohibited 45 days after August 6. What “transaction” means won’t be spelled out until around the time the orders come into effect.

While TikTok’s US operations may be sold to Microsoft or another American company before the deadline, WeChat is unlikely to be saved. To many Chinese living in the US, the app may have been sentenced to death.

To them, a ban on WeChat means they won’t be able to talk to their families in China anytime they like, nor exchange information with one another about everything from the latest movies to breastfeeding, often in specialist chatting groups.

It means American businesses will find it hard to communicate with their Chinese suppliers, customers, or partners, and Chinese students—who’ve already faced a battering over allegations of espionage and various immigration controls—will be less likely to come here to study.

It also means the last effective two-way channel between China and the US will be closed, as all other non-China-owned communication apps are banned in China. To be sure, WeChat has been used by trolls in China to spread disinformation about events in the US, China, and the world, but it also gave people living here the chance to counter them with the truth.

If the WeChat clampdown had occurred six months ago, it would have made it much more difficult for Chinese in the US to locate and import millions of pieces of invaluable personal protective equipment that were donated to hospitals, clinics, nursing homes and police precincts here.

It’s the restraints on his own supporters that could backfire most for Trump with an election looming.

The Democrats used to be able to assume they had overwhelming support from the Chinese community in the US. But in recent years, some new immigrants have put their feet firmly in the Trump camp. This is partly because of his pro-business policies, but also because they feel Democrat leaders in cities like New York have ignored concerns about education and law and order policies in particular.

Phone and Accessory Deals

We’ve got three great Android phones you can get for a little less than their original price. Check out our Best Android Phones and Best Cheap Phones guides for more recommendations.

• Google Pixel 4 XL for $836 ($63 off): The Pixel 4 XL has been discontinued by Google, but it’s still a good buy. This isn’t the lowest price we’ve seen, but it likely won’t go on sale for much longer as stock runs out. It has an excellent camera, a really nice screen with a 90-Hz refresh rate, and you get extra perks like wireless charging. The downside? Battery life is unremarkable.

• OnePlus 7T T-Mobile Version for $399 ($200 off): This phone was our runner-up pick in our Best Android Phones guide for a better part of the year. We recently took it out because the unlocked model is no longer in stock (it looks like OnePlus is trying to clear out its inventory). But you can get the T-Mobile version for $200 off. This phone was already a great value, but at this price it’s a steal. You get an amazing screen, phenomenal performance, and solid cameras. It should work on other GSM networks like AT&T, but unlocking it may be a hassle.

• Moto Edge for $500 ($200 off): This is a limited-time discounted launch price—it will go back to its $700 MSRP eventually. At $500, it’s a pretty solid phone with good performance, almost two-day battery life, and decent cameras. The screen curves toward the edges, which makes it a bit unpleasant to hold, but if you like the look, you’ll enjoy this phone.

• Totallee iPhone Cases for $5 ($30 off): Totallee is clearing out its inventory for older iPhones to make room for the upcoming iPhone 12. So if you have or are getting an iPhone 11 Pro, 11 Pro Max, iPhone XS, or iPhone X, you can nab select cases for just $5. Some screen protectors are also similarly discounted.

How to Turn on Nearby Share

The easiest and universal way to find Nearby Share is to head to your phone’s Settings menu, scroll down to Google, tap on Device connections, and here you should see Nearby Share. If it’s not there, you most likely do not have the feature yet. The other way to find it is through Settings > Connected devices > Connection preferences > Nearby Share, but this is where the menus might look different based on your phone.

Sticking with the first approach of finding it in the Google section of your Settings menu, tap on Nearby Share. Toggle it on, and in the process, you can change your Device Name and choose your Device Visibility. If you don’t want to share your name when sending files or photos with other nearby devices, then it’s a good idea to change your device name to something more nondescript. You can only use Nearby Share with people in your contacts list.

In terms of Device Visibility, you have three options: All Contacts, Some Contacts, and Hidden. Choosing the first option means your phone will be visible to your contacts that have Nearby Share turned on, and you’ll see devices near you with Nearby Share open. Some Contacts, as the name suggests, lets you toggle select people in your contacts list to use Nearby Share with. And Hidden means no one nearby will be able to see your device, but you can still see your contacts’ devices if they are trying to share something nearby.

There is a big caveat with Nearby Share. To use it, you’ll need to have the email addresses for all your contacts (the one they use for their Google Account) stored in their contact information. Alternatively, if your contact has verified their Google Account with a phone number, you’ll be able to use Nearby Share with them. To connect your phone number to your Google Account, head here on your phone and toggle on your device. It might take some time to authenticate.

Back in the Nearby Share settings, you can also choose whether you want to send stuff via Data, Wi-Fi Only, or Without Internet. If you don’t have an unlimited data plan, it might be a good idea to choose the latter two options.

How to Use Nearby Share

Whenever you want to share something with a friend or family member nearby, whether it’s an address in Google Maps, a photo, a file, or a web link, simply tap the share button, and from the Share Menu, find and tap on Nearby Share. Your phone will start searching for devices nearby you can share with.

The person you’re sharing with will need to be relatively close, and they may need to tap on a pop-up notification to become visible to you. You and the person you’re sharing stuff with may get a prompt to turn on Bluetooth and Location if they aren’t on already.

Once they’re visible, tap their device name (they will need to accept), and that’s it! The sharing process will begin and it should only take a few seconds, depending on what you’re sending.

Eventually, Google says Nearby Share will work on Chromebooks, allowing you to quickly send stuff from your phone to your ChromeOS-powered laptop with just a few taps.

This story originally appeared in The Guardian and is part of the Climate Desk collaboration.

Satellite images have revealed 11 previously unknown emperor penguin colonies in Antarctica, boosting the number of known colonies of the imperilled birds by 20 percent.

The discoveries were made by spotting the distinctive red-brown guano patches the birds leave on the ice. The finds were made possible by higher-resolution images from a new satellite, as previous scans were unable to pick up smaller colonies.

Two of the colonies were a particular surprise. They were found far from the coast, living on sea ice that is anchored to grounded icebergs, a location never seen before.

The new colonies are thought to number a few hundred penguins each, which is smaller than average, so the discoveries increase the total population of emperor penguins by a smaller proportion of about 5 to 10 percent.

Emperor penguins are the only penguins that breed on sea ice, rather than land, making them especially vulnerable to the climate crisis. All the new colonies are in areas that are at risk, and researchers say these will be the “canaries in the coal mine” as global heating increasingly affects Antarctica.

“The [new colonies] are an exciting discovery,” said Peter Fretwell, at the British Antarctic Survey (BAS), who led the research. “Whilst this is good news, the colonies are small and so only take the overall population count up to just over half a million penguins.”

Philip Trathan, also at BAS, said: “The new breeding sites are all in locations where recent model projections suggest emperor penguins will decline. These birds are therefore probably the canaries in the coal mine–we need to watch these sites carefully as climate change will affect this region.”

Fretwell said one of the colonies was 180 kilometers (112 miles) from the Antarctic continent: “Many of the penguin scientists we have talked to were disbelieving, as normally you expect them to be at the coast.” Emperor penguins need stable sea ice, usually attached to land, for nine months of the year to breed successfully.

There were only 30 colonies known a decade ago, as they are usually in remote and inaccessible locations, where temperatures can fall as low as -50 Celsius (-58 Fahrenheit) in winter. But then Landsat satellite images began to be used. These have a resolution of 30 meters, which is enough to spot the larger colonies.

This week marked the first-ever online-only Black Hat and Defcon security conferences, both of which still produced impactful work despite going remote. But before you dive into everything that’s broken, start off with a tale of perseverance that starts with the private keys needed to recover $300,000 of bitcoin trapped in an old zip file.

Dutch researchers figured out how to mess with traffic lights across at least 10 cities in the Netherlands. At most they could have caused a few traffic jams—not multicar pileups—but it’s an important reminder about the potential fragility of connected city infrastructure. Also fragile: a file type known as Symbolic Link, which gave Apple hacker Patrick Wardle the foothold he needed to compromise macOS in a since-patched vulnerability chain. After months of qualifying rounds, the US Air Force’s Hack-a-Sat finals arrived, albeit remotely thanks to the Covid-19 pandemic. And speaking of satellites, hackers have built cheap ground stations that allow anyone to intercept their transmissions. Neat!

We also took a look at how IoT botnets made from high-wattage machines like home appliances could potentially be used to game the energy markets. Decades-old flaws in email protocols make it possible for anyone to hide their true identity, a scary thought given the prevalence of high-stakes phishing attacks. And hackers took over dozens of subreddits Friday, plastering their pages with MAGA imagery and comments.

We talked to former national intelligence official Sue Gordon about how to prevent the next “Cyber 9/11.” We explained why the Trump administration’s TikTok obsession is just a distraction. And we looked at how Chinese hackers have run roughshod over Taiwan’s semiconductor industry, hitting at least seven companies in what researchers are calling Operation Skeleton Key.

This week, the National Security Agency shared a three-page primer on how to limit your location data exposure. They would know! As a baseline it’s a healthy reminder that your smartphone feeds on your location and that a lot of unscrupulous, invisible parties try to sell and obtain it. But it also provides some actually useful advice, especially if this isn’t a topic you’ve given much thought to already.

In addition to turning off location services on your device, the NSA says, you should turn off Bluetooth and Wi-Fi whenever you’re not using them. For extra caution, turn on Airplane Mode whenever you’re not actively using your phone. Turn off or decline location-sharing permissions for apps whenever possible—including your browser—or at the very least limit their ability to check your location to when you have the app open. Reset your phone’s advertising ID at least weekly to confound the ad networks that track you—we have our own guide on how to do that here. Don’t use iOS and Android’s FindMy or FindMyDevice features, and consider using a trusted VPN provider.

There is also a folder dedicated to the Intel Management Engine, but its contents, too, aren’t anything Intel integrators don’t already know. They’re test code and recommendations for when and how often to run those automated tests while designing systems that include an Intel CPU with the Intel ME.

One of the dump’s newer bits included “Whitley/Cedar Island Platform Message of the Week,” dated May 5. Cedar Island is the motherboard architecture that lies beneath both Cooper Lake and Ice Lake Xeon CPUs. Some of those chips were released earlier this year, while some have yet to become generally available. Whitley is the dual-socket architecture for both Cooper Lake (14 nm) and Ice Lake (10 nm) Xeons. Cedar Island is for Cooper Lake only

Some contents provide a cryptic reference to voltage failures in some Ice Lake samples. It’s not clear if the failures apply to actual hardware delivered to customers or if they’re happening on reference boards Intel provided to OEMs for use in designing their own boards.

While Intel said it doesn’t believe the documents were obtained through a network breach, a screenshot of the conversation Kottmann had with the source provided an alternate explanation. The source said that the documents were hosted on an unsecured server hosted on Akamai’s content delivery network. The source claimed to have identified the server using the nmap port-scanning tool and from there, used a python script to guess default passwords.

Here’s the conversation:

source: They have a server hosted online by Akami CDN that wasn’t properly secure. After an internet wide nmap scan I found my target port open and went through a list of 370 possible servers based on details that nmap provided with an NSE script.

source: I used a python script I made to probe different aspects of the server including username defaults and unsecure file/folder access.

source: The folders were just lying open if you could guess the name of one. Then when you were in the folder you could go back to root and just click into the other folders that you didn’t know the name of.

deletescape: holy shit that’s incredibly funny

source: Best of all, due to another misconfiguration, I could masqurade as any of their employees or make my own user.

deletescape: LOL

source: Another funny thing is that on the zip files you may find password protected. Most of them use the password Intel123 or a lowercase intel123

source: Security at it’s finest.

Kottmann said they didn’t know the source well, but, based on the apparent authenticity of the material, there’s no reason to doubt the source’s account of how it was obtained.

The Intel spokeswoman didn’t immediately provide a response to the claim.

Many onlookers have expressed alarm that the source code has comments containing the word backdoor. Kottmann told Ars that the word appeared two times in the source code associated with Intel’s Purely Refresh chipset for Xeon CPUs. So far, there are no known analyses of the source code that have found any covert methods for bypassing authentication, encryption, or other security protections. Besides, the term backdoor in coding can sometimes refer to debugging functions or have other benign meanings.

People are also lampooning the use of the passwords Intel123 and intel123. These are no doubt weak passwords, but it’s unlikely their purpose was to secure the contents of the archive files from unauthorized people.

The social network defined key government officials as senior officials that are the voice of the nation-state abroad, including foreign ministers, institutional entities, ambassadors, official spokespeople and key diplomatic leaders.

For now, this policy only applies to the five permanent members of the U.N. Security Council—China, France, the Russian Federation, the U.K. and the U.S.—but the social network said it plans to continue expanding this approach to additional countries over time.

The social network clarified in a blog post, “For transparency and practicality, we are starting with a limited and clearly defined group of countries before expanding to a wider range of countries in the future. We believe this is an important step so that when people see an account discussing geopolitical issues from another country, they have context on its national affiliation and are better informed about who they represent. At this time, we’re not labeling the personal accounts of heads of state, as these accounts enjoy widespread name recognition, media attention and public awareness. Institutional accounts associated with their offices that change over depending on election results will be labeled, however.”

Twitter defined state-affiliated media entities as outlets where the state exercises control over editorial content via financial resources, political pressures (direct or indirect) or control over production and distribution, and its new policy applies to the entities themselves, their editors in chief and their senior staff.

The social network said state-affiliated media accounts or their tweets will no longer be amplified via its recommendation system on timeline and through notifications and search.

Twitter explained, “Unlike independent media, state-affiliated media frequently use their news coverage as a means to advance a political agenda. We believe that people have the right to know when a media account is affiliated directly or indirectly with a state actor. State-financed media organizations with editorial independence, like the BBC in the U.K. or NPR in the U.S., will not be labeled. As part of the development of this process, we consulted with a number of expert groups, including members of the Digital and Human Rights Advisory group in Twitter’s Trust & Safety Council.”

Clicking the labels in either category will bring users to this help center page explaining the policy and refer them to the Twitter Transparency Report for additional information.

Twitter said accounts that are labeled will be notified, and the account owner can appeal if it believes this was done in error.

The social network wrote in its blog post, “Twitter provides an unmatched way to connect with and directly speak to public officials and representatives. This direct line of communication with leaders and officials has helped to democratize political discourse and increase transparency and accountability. We also took steps to protect that discourse because we believe political reach should be earned, not bought. In 2019, we banned all state-backed media advertising and political advertising from Twitter. Today, we’re expanding the types of political accounts we label.”
