Give users even more confidence in your software by submitting it to Apple for notarization.
Notarization gives users more confidence that the Developer ID-signed software you distribute has been checked by Apple for malicious components. Notarization is not App Review. The Apple notary service is an automated system that scans your software for malicious content, checks for code-signing issues, and returns the results to you quickly. If there are no issues, the notary service generates a ticket for you to staple to your software; the notary service also publishes that ticket online where Gatekeeper can find it.
When the user first installs or runs your software, the presence of a ticket (either online or attached to the executable) tells Gatekeeper that Apple notarized the software. Gatekeeper then places descriptive information in the initial launch dialog to help the user make an informed choice about whether to launch the app.
Gatekeeper lets the user know that Apple notarized the app being launched.
You can notarize several different types of software deliverables, including:
* macOS apps * Non-app bundles, such as kernel extensions * Disk images (UDIF format) * Flat installer packages
Notarization also protects your users if your Developer ID signing key is exposed. The notary service maintains an audit trail of the software distributed using your signing key. If you discover unauthorized versions of your software, you can work with Apple to revoke the tickets associated with those versions.
Beginning in macOS 10.14.5, all new or updated kernel extensions and all software from developers new to distributing with Developer ID must be notarized in order to run. In a future version of macOS, notarization will be required by default for all software.
Notarization requires Xcode 10 or later. Building a new app for notarization requires macOS 10.13.6 or later. Uploading and stapling an app requires macOS 10.12 or later.
Appleʼs notary service requires you to adopt the following protections:
* Enable code-signing for all of the executables you distribute. * Enable the Hardened Runtime capability for your executable targets, as described in Enable hardened runtime. * Use a “Developer ID” application, kernel extension, or installer certificate for your code-signing signature. (Donʼt use a Mac Distribution or local development certificate.) For more information, see Create, export, and delete signing certificates. * Include a secure timestamp with your code-signing signature. (The Xcode distribution workflow includes a secure timestamp by default. For custom workflows, include the --timestamp option when running the codesign tool.) * Don’t include the com.apple.security.get-task-allow entitlement with the value set to any variation of true. If your software hosts third-party plug-ins and needs this entitlement to debug the plug-in in the context of a host executable, see Avoid the Get-Task-Allow Entitlement. * Link against the macOS 10.9 or later SDK.
Apple recommends that you notarize all of the software that you’ve distributed, including older releases, and even software that doesn’t meet all of these requirements or that is unsigned. Apple’s notary service uses a variety of methods, including telemetry, to determine which of the above rules to relax for preexisting software. For more information, see Notarize Your Preexisting Software.
Some preexisting software might not run properly after being successfully notarized. For example, Gatekeeper might find code signing issues that a relaxed notarization process didn’t enforce. Always review the notary log for any warnings, and test your software before distribution.
When you enable the extra security enforced by the hardened runtime, as notarization requires, this impacts both your app and any plug-ins that your app hosts. Plug-ins don’t declare their own entitlements. Instead, they inherit the entitlements of the host process. Therefore, a host app must include all the entitlements that prospective plug-ins require, even when the plug-ins are notarized separately.
Also include resource access entitlements, like the Address Book or Location access entitlements, and the related purpose strings, that support your app’s plug-ins. For example, if a Print Dialog Extension (PDE) that provides fax services wants to access a user’s contact list, the host executable must declare the Address Book Entitlement and include the NSContactsUsageDescription purpose string in its Information Property List for the plug-in to operate.
For a complete list of hardened runtime entitlements, see Hardened Runtime Entitlements. For information about usage strings, see Accessing Protected Resources.
On macOS 10.14.x, for executables using the hardened runtime, PDEs load only if the host executable has the Disable Library Validation Entitlement.
Before distributing your app directly to customers, your Account Holder must sign the app with your Developer ID. Xcode’s Organizer window includes a workflow for generating a distributable version of your app. In Xcode 10 and later, this workflow includes an option to notarize your app automatically. To notarize your app using this workflow, do the following:
1. Open your Xcode project.
2. Create an archive of your app.
3. Open Xcodeʼs Organizer window.
4. In the Archives tab, select the archive you created.
5. Click Distribute App to view the distribution options.
6. Choose Developer ID for your method of distribution.
7. Click Next.
8. Choose Upload to send your archive to the Apple notary service.
9. Click Next.
When distributing an app, choosing the upload option sends the app to Apple to be notarized.
When you click Next, Xcode uploads your archive to the notary service. When the upload is complete, the notary service begins the scanning process, which usually takes less than an hour. While the notary service scans your software, you can continue to prepare your archive for distribution. For example, you can export the archive and perform any final testing that you require prior to making your software available to customers.
When the notarization process finishes, Xcode downloads the ticket and staples it to your archive. At that point, export your archive again to receive a distributable version of your software that includes the notary ticket.
For more information about how to use the Xcode UI to upload your software, see Upload a macOS app to be notarized.
Notarizing your preexisting software lets Gatekeeper warn users when they try to run it. It also helps the notary service distinguish your legitimate software from variants that have been tampered with. You can notarize an existing disk image, installer package, or ZIP archive containing your app.
To notarize your preexisting software, do the following:
You don’t need to rebuild or re-sign your software before submitting it for notarization, but you must use Xcode 10 to perform the notarization steps. Submit everything you’ve previously released, as well as your most recent version, to protect users who continue to use older versions of your software.
For tips on how to resolve issues that can occur during notarization, see Resolving Common Notarization Issues.
If you use an automated build system, you can integrate the notarization process into your existing build scripts. The altool and stapler command-line tools (included with Xcode) allow you to upload your software to the Apple notary service, and to staple the resulting ticket to your executable.
For information about how to incorporate notarization into your custom build scripts, see Customizing the Notarization Workflow.

On the NATO's 70th anniversary
The U.S. Congress invited Jens Stoltenberg to demonstrate its unwavering support for NATO amid rising tensions with Russia over the 1987 Intermediate-Range Nuclear Forces treaty aimed at preventing a nuclear confrontation.
“We do not want a new arms race. We do not want a new Cold War. But we must not be naive. An agreement that is only respected by one side will not keep us safe,” said Jens Stoltenberg the NATO Secretary-General.
Drumpf’s individual relationship with NATO has been turbulent, partly because he wants closer relations with Russia, though his administration is pressuring fellow NATO member Turkey to drop an arms purchase from Moscow.
As policymakers in NATO capitals draft flowery speeches for their ministers, and caterers in Washington place their orders for just the right vintage of champagne, allies are making a series of decisions that are rapidly eroding alliance unity. Too few members today—the United State included—see a need to prioritize NATO solidarity. That’s weakening members’ collective hand against the alliance’s adversaries and casting a dark shadow over the 70th anniversary.Also, just saying: It's not even about spending more on interior affairs such as pensions or education, since both of them are heavily underspent, they are saved to death, one could tell. Our schools are degrading, fading into nowhere, while oure retirees either have the façade chance of buying shares on the stockmarkets (with the money they don't have), or dying in poverty. Our financial secretary Olaf Scholz avoids any kind of spendings to maintain the debt cut, to create no debts within the entire year. He's like the German Paul Ryan, although Ryan admitted he was a fiscal Conservative, while Mr. Scholz still claims to be a SocDem.
But the budget decision was never about NATO. Instead, Berlin’s defense spending debate became a choice between bending to Drumpf’s demands or spending more on domestic priorities such as pensions or education. It was also an attempt by the Social Democrats to differentiate themselves from Merkel’s Christian Democrats.
These S-400 batteries, which Russia plans to deliver in July, are unable to connect with the alliance’s early warning systems. U.S. military commanders also worry that the S-400s would compromise the security of the F-35 fighter jets that Turkey just purchased (as well as the F-35s that other NATO allies fly).
3. 93.1 WIBC:
"In 2014 at the NATO summit in Whales, all of our allies agreed of their own accord, to spend at least two percent of their GDP on defense. The United States has done all that and more," said Pence. "Twenty-three of the 28 member nations were still not paying what they should be paying."Instead of judging over other NATO members for not paying their 1.5 percent of their GDP into military, your country would be better off spending more in favour of education, not only in privately owned schools, but also into public schools which are attended by the general public. Just saying, you're setting the wrong scopes. Oh, and also: I don't know whether it was a mistake of yours in terms of pronounciation, but Wales is spelled without an .
Pence pointed at Germany, saying they have a stout economy, and yet would not devote the two percent in their latest budget proposal. He also criticized Germany for their increasing reliance on Russia for energy.1.45 percent is just fine, dude.
Pence said NATO members have opened up dialog with other countries in the region, like Australia, Singapore and South Korea.
NATO’s biggest long-term challenges are a diminishing appetite from the U.S. for security guarantees for Europe, as exemplified by the Drumpf administration's highly ambivalent attitude toward the alliance. This will be compounded by Brexit and the attendant centrifugal forces pulling at Europe, which will in turn undermine political unity — the true Achilles’ heel of an organization that operates on consensus. Finally, there will be downward pressure on defense budgets on both sides of the Atlantic as nations try to address social and infrastructure needs.
I think after the addition of North Macedonia and Montenegro, there will probably be a pause in actual admissions. If Finland and Sweden decide they’re sufficiently threatened by Russia, they may decide to move from a very close partnership to actual membership.
The strategic challenge of the future requires a level of creativity and engagement in developing technologies with a mindset that you need these technologies in place to deter, but you don’t necessarily need to use them.
One other theater NATO should address in the coming decade is the Arctic. The Arctic is a strategically important region, and ignoring its importance for collective security is short-sighted. NATO must take on a greater role in this region, starting with developing a NATO Arctic strategy.
“Since its creation in 1949, NATO has done more to promote democracy, peace, economic prosperity, and security in Europe than any other multilateral organization. NATO continues to form the backbone of security and stability in Europe, and serves as the cornerstone of America’s greatest strength, our alliances with likeminded nations.
The North Atlantic region must stand together in meeting the myriad challenges we collectively face. A strong, vibrant transatlantic partnership with the NATO alliance at its core is, and will remain, essential for ensuring peace, prosperity, and geopolitical stability in the 21st century.”

Does the cloud have a future ?
a) Computers continue to get cheaper
b) All the mindbogglingly complicated crapware for cloud orchestration gets replaced by something easy to use
c) Things like AI either exit their overhype phase and/or - I would argue inevitably - become vastly more efficient
Why won't the cloud go the same way as every other bureau service in history ? They progress from 'so much easier' through 'too much of my budget but I guess we need it' to disruption where someone solves the boring 5% of the problem that 90% of the users care about and it becomes a product you lease then one you buy in house.
At the point where you have a 21" rack in the office that has a red network switch and a blue network switch on it and you add computing power or storage nodes by inserting a new node and you connect the blue port to the blue switch with the blue wire, and the red port to the red switch with the red wire and press the pair button would we need the giant cloud providers any more ?
Or were IBM right - the world only needs five computers - Google, Amazon, Tencent. Baidu, ....

#HackerNews #build #cars #cities #future #get #must #our #out #the
This story appears in the April 2019 issue of National Geographic magazine.
The purpose of cities is to bring people together. In the 20th century, we blew them apart. One day last year, Peter Calthorpe took me on a drive through some of the wreckage. He wanted to show me how he proposes to make cities whole again.
Calthorpe is an architect who in the late 1970s helped design one of the first energy-efficient state office buildings, which still stands in Sacramento, California. But he soon widened his focus. “If you really want to affect environmental outcomes and social outcomes, it’s not shaping a single building that matters,” he says. “It’s shaping a community.”
Today he runs a small but globally influential urban design firm, Calthorpe Associates. In his spare, airy office in Berkeley, the charter of the Congress for the New Urbanism hangs framed on the wall, denouncing “the spread of placeless sprawl.” Calthorpe helped launch the group in 1993. The struggle is long and ongoing.
We waited until late morning for the traffic to settle a bit, then got into Calthorpe’s midnight blue Tesla and set a course for Silicon Valley, south of San Francisco on the far side of the distended metropolis.
WELWYN GARDEN CITY, ENGLAND A century ago, when British urban planner Ebenezer Howard envisioned two “garden cities” north of London, people were starting to flee overcrowded cities in Europe and America. Some of Howard’s ideas still seem forward-looking, such as the way he gave Welwyn residents easy access to both green spaces and the metropolis—London is just a half hour away by train.
“The problem with urban environments that are auto oriented,” he said, as we wound our way toward the Bay Bridge, “is that if there’s no choice, if the only way to get around is in a car, lo and behold, people are going to use cars too much. Too much for the climate, too much for people’s pocketbooks, too much for the community in terms of congestion, too much for people’s time. I mean, every way you measure it, it has a negative—no walking is a prescription for obesity. Air quality feeds into respiratory illnesses.”
In the 1990s Calthorpe scored a breakthrough: He helped persuade Portland, Oregon, to build a light-rail line instead of another freeway and to cluster housing, offices, and shops around it. “Transit-oriented development” sealed his reputation as an urban visionary; in Beijing, I met an environmental scientist who has taken many Chinese planners to visit Portland. It was less of a new idea, Calthorpe said, than a call “to reinvent the old streetcar suburb, where you had fabulous downtowns and you had walkable suburbs, and they were linked by transit.”
On the bridge, despite leaving late, we hit stop-and-go traffic.
In Calthorpe’s utopia, in China or America or elsewhere, cities would stop expanding so voraciously, paving over the nature around them; instead they’d find better ways of letting nature into their cores, where it can touch people. They’d grow in dense clusters and small, walkable blocks around a web of rapid transit. These cities of the future would mix things up again: They’d no longer segregate work from home and shopping, as sprawl does now, forcing people into cars to navigate all three; they’d no longer segregate rich from poor, old from young, and white from black, as sprawl does, especially in the United States. Driving less, paving less, city dwellers would heat the air and the planet around them less. That would slow the climate change that threatens, in this century, to make some cities unlivable.
To do all this, in Calthorpe’s view, you don’t really need architectural eye candy or Jetsons technology—although a bit of that can help. You need above all to fix the mistakes and misconceptions of the recent past.
BAKU, AZERBAIJAN This oil-rich capital, the country’s largest city, has followed the Dubai model of urban development: trophy buildings first, an overall plan later. The Flame Towers are meant to evoke flares at natural gas seeps; at night, simulated flames dance on their facades, which are covered with LEDs. The skyscrapers house an upscale hotel, luxury apartments, and a mall with a Lamborghini showroom.
South of the San Francisco airport, Calthorpe turned off the Bayshore Freeway. We were headed for Palo Alto, where he grew up in the 1960s, but we’d really come to drive El Camino Real—the road once traveled by Spanish colonists and priests. “It was the old Mission Trail,” he said. “And right now, it runs through the heart of Silicon Valley, and it’s just low-density crap.”
Town after town spooled by, tire shop after U-Haul dealer after cheap motel. El Camino is one of the oldest commercial strips in the western United States, and it’s not the ugliest. To Calthorpe, its interest is not as an eyesore but as an opportunity. Not many people live on the road, because it’s mostly zoned for commercial use. Yet Silicon Valley is desperately short of housing. Tens of thousands of people commute in cars from throughout Northern California. In Mountain View, home of Google, hundreds actually live in parked cars.
Along the 45-mile stretch of El Camino between San Francisco and San Jose, within half a mile of the road, there are 3,750 commercial parcels occupied by a motley collection of mostly one- or two-story buildings. Calthorpe knows this from the software he and his colleagues have developed, called UrbanFootprint, which draws on a nationwide parcel-by-parcel database and a series of analytical models to game out visions of the future for cities to consider. If El Camino were lined with three- to five-story apartment buildings, Calthorpe explained, with stores and offices on the ground floor, it could hold 250,000 new homes. You could solve the Silicon Valley housing shortage and beautify the place at the same time, while reducing carbon emissions and water consumption and wasted human hours.
ROTTERDAM, NETHERLANDS In the city’s historic district, the new Market Hall aims to inspire with its originality—but also to create “a space where we could celebrate and we could meet each other,” says architect Winy Maas. The arched apartment building covers a food market that’s open daily, as well as bars and restaurants.
In that 45-mile “ribbon of urbanism,” children would walk to school again. Their parents would walk to the grocery store and walk or bike to work—or jump on public transit to head up or down the strip. Transit is the key: It would have to be ubiquitous and fast. But it wouldn’t be light rail this time, Calthorpe said. That’s too expensive now, and a better technology is coming.
It’s one many urban planners are terrified of: driverless autonomous vehicles, or AVs. Calthorpe himself thinks that, if AVs are left to individuals or the likes of Uber or Lyft, they will metastasize sprawl. He wants to harness the technology to benefit communities. Down the center of El Camino, on dedicated, tree-lined lanes, he would run autonomous shuttle vans. They’d arrive every few minutes, pass each other at will, and stop rarely, because an app would group passengers by destination. On their protected lanes, as Calthorpe envisions it, the little robots wouldn’t run over people—and the technology wouldn’t run over our world with its unintended consequences.
Calthorpe is a onetime hippie, but of the techno-friendly Whole Earth Catalog kind. In the late 1960s he taught at an alternative high school in the Santa Cruz Mountains, helping the kids build geodesic domes. The valley below wasn’t yet nicknamed for Silicon; it was still the Valley of Heart’s Delight, covered in fruit orchards. In the foothills, an interstate highway was under construction, to relieve congestion on El Camino and the Bayshore Freeway. “In those days, you couldn’t even see the valley,” Calthorpe recalled. “It was just a sea of smog. It was just really clear that something was profoundly wrong.” Today there’s less smog, but the city is still broken, and on his good days, it still seems fixable to him.
When the Congress for the New Urbanism held its annual meeting last year in Savannah, Georgia, the keynote speaker was Jan Gehl, an urban designer from Copenhagen. An oracular octogenarian, Gehl is revered for his simple insights: Architects and urban designers should build “cities for people” (the title of one of Gehl’s books, translated into 39 languages), not cars. They should pay attention to the “life between buildings” (another book title), because it’s crucial to our well-being. Gehl has spent decades observing how people behave in public spaces, collecting data on which kinds encourage civic life and which tend to be dispiriting and empty.
“There is great confusion about how to show the city of the future,” he said as we sat at an outdoor café on a square shaded by live oaks. From time to time a horse clopped by, pulling a carriage full of tourists. “Every time the architects and visionaries try to paint a picture, they end up with something you definitely would not like to go anywhere near.”
SINGAPORE Can a high-rise city be a garden city? Singapore subsidizes vertical gardens like these on the 627-foot Oasia Hotel. Designed by a local firm, the building is cooled by 54 species of trees and flowering vines, which attract bugs and birds—and soothe jangled nerves.
He opened his laptop and showed me a Ford Motor Company website called the City of Tomorrow. The image showed a landscape of towers and verdant boulevards with scattered humans and no sign of them interacting.
“Look at how fun it is to walk there,” Gehl said dryly. “There are only a few hostages down there among the autonomous cars.”
“Towers in the park,” as New Urbanists call this kind of design, is a legacy of modernist architecture, whose godfather was Le Corbusier. In 1925 he proposed that much of central Paris north of the Seine be razed and replaced with a grid of 18 identical glass office towers, 650 feet high and a quarter mile apart. Pedestrians would walk on “vast lawns” gazing up at “these translucent prisms that seem to float in the air.” Cars would whiz by on elevated expressways. Cars, Le Corbusier thought, had made the streets of Paris, “this sea of lusts and faces,” obsolete.
Like most of Le Corbusier’s ideas, the Plan Voisin was never built. But his influence was nonetheless global. It’s seen in the notorious housing projects of American city centers—some since demolished—and in the corporate office parks that dot the suburban landscape. It lives on too in the dozens of entirely new cities now being planned and built all over the world, especially in Asia. Many of those cities claim to prioritize walking and public transit, says Sarah Moser, a McGill University urban geographer who has studied them, but most in fact don’t. Putrajaya, Malaysia’s new federal administrative center, is a good example: Half of it is devoted to green space. But as Moser points out, “it takes a lot of walking to get from building to building.”
The influence of Le Corbusier is felt especially in the new urban districts that China has slapped up over the past four decades. Calthorpe, who spoke at the Savannah conference, argued that those regiments of identical apartment towers, lined up on quarter-mile-long “superblocks,” have something in common with American suburbs, as different as they appear.
“There’s one unified problem,” he said, “and it’s sprawl.” The essence of sprawl, he explained, is “a disconnected environment.” People living in high-rise towers in a park can be just as disconnected—from their neighbors and from the unwalkable street below—as people living on suburban cul-de-sacs. In China’s new towns, narrow streets lined with shops have given way to 10-lane boulevards, crowded with cars rather than bicyclists and pedestrians. “The social and economic fabric is being destroyed,” Calthorpe said.
Sprawl happened in the United States for reasons that made it seem like a good idea at the time. Millions of soldiers had come home from World War II to overcrowded, run-down cities; their new families needed a place to live. Driving to the suburbs felt liberating and modern. In China, sprawl happened for good reasons too.
In People’s Square in Shanghai I toured an exhibit on the city’s history with Pan Haixiao, a transportation researcher at Tongji University. When he arrived as a student in 1979, traffic was already terrible, he said—not because there were so many cars but because of “the very fine urban fabric,” the dense network of narrow streets. In those days, it could take Pan two hours to go downtown from the university, less than four miles away.
Wouldn’t it have been quicker to walk? I asked.
“At that time, we didn’t have enough food,” Pan said. “If you walk, you’ll feel very tired. We were always hungry when I was a student.”
LA PAZ, BOLIVIA Transit binds a city: When La Paz sent its first cable cars sailing over congested mountain roads in 2014, it linked mostly poor El Alto to downtown, 1,300 feet below. By 2018 nine lines were carrying 250,000 people a day. Cabins arrive every 10 to 12 seconds.
LA PAZ, BOLIVIA The Orange Line cable cars pass over La Llamita cemetery. A 10th line is scheduled to open this spring and an 11th in the future.
In the 40 years since Deng Xiaoping decreed the “reform and opening” of China, as its population swelled to 1.4 billion, the country has lifted hundreds of millions of people out of poverty. It has done so essentially by drawing them from the countryside to factory jobs in cities. China’s breakneck urbanization is all the more remarkable for having been preceded by Mao Zedong’s Cultural Revolution, which sent millions of people the other way, from cities into the country.
“After the Cultural Revolution, the first thing was to make everybody have a home and have enough food,” said He Dongquan, a Beijing environmental scientist who is China director for Energy Innovation, a U.S.-based think tank. He grew up in the ’70 and ’80s in Baotou, Inner Mongolia, an industrial city his parents had helped build. It’s now economically distressed—but in its prime it gave young He access to electricity, clean water, and education, for which he considers himself lucky.
As the urbanization drive began, He said, there was a rush to build apartments—and the quickest way was to churn out cookie-cutter towers on superblocks. The financial incentives were powerful, and not just for developers; Chinese city governments can get half or even more of their local revenue from selling land rights. Urban design niceties were overlooked—although following the dictates of feng shui, the towers generally were lined up in orderly, south-facing rows.
Just as with American suburbs, which helped realize millions of American dreams, the results are great, to a degree. The average Chinese family now has 360 square feet of space per person, four times the average of two decades ago. But the spaces between the buildings are uninviting, He said, so people don’t use them.
“Everybody feels lonely and nervous,” He said. Fearing crime, residents demand fences, turning superblocks into gated communities. The city becomes even less friendly and walkable.
Meanwhile, in the past 20 years, the number of private cars in China has gone from negligible to nearly 190 million. Beijing now has seven concentric ring roads rippling outward from the Forbidden City. Seventy percent of the transport infrastructure investment in rapidly developing cities is for cars, said Wang Zhigao, director of the low-carbon cities program at the Energy Foundation China, an internationally funded nonprofit.
Public transit is excellent, by American standards, but not good enough to lure enough people out of cars. Part of the problem, in Beijing and other cities, is the sprawling urban form—the legacy of all those years of building hastily. “If we don’t make the urban form right, it will be there for hundreds of years,” Wang said. “If we continue to provide a driving environment, people will drive, and we’ll still be high carbon, even with electric vehicles.” China still gets most of its electricity from coal.

A decade ago, Wang and He got wind of a new development called Chenggong, in the southwestern city of Kunming. Planned for 1.5 million people, it was a typical Chinese new town: The main street was 90 yards across from curb to curb, 200 from building to building. “We contacted Peter and some other experts then, and they were shocked,” Wang recalled. “They said, ‘This street is not for human beings.’ ”
The Energy Foundation flew Calthorpe and an architect from Gehl’s firm to Kunming to talk with city officials. “That first lecture, they started buying into the ideas,” Wang said. Ultimately the Energy Foundation paid for Calthorpe to redo the plan for Chenggong. “It was already planned, and they already had started the infrastructure,” Calthorpe recalls. “They had already laid out the superblocks.” Where it was still possible, he divided each one into nine squares, like a tic-tac-toe board, with smaller roads. He put the buildings closer to the street, with stores on the ground level below offices and apartments.
The project, still under construction, became the first of many that Calthorpe and a young colleague, Zhuojian (Nelson) Peng, have worked on in China. It got the attention of the national housing ministry. And it reinforced a change in mind-set that already was bubbling up from Chinese urban planners—one that then got ratified in a startling way. In 2016 the Communist Party Central Committee and the State Council, the highest organs of the state, issued a decree: From now on Chinese cities were to preserve farmland and their own heritage; have smaller, unfenced blocks and narrower, pedestrian-friendly streets; develop around public transit; and so on. In 2017 the guidelines were translated into a manual for Chinese planners called Emerald Cities. Calthorpe Associates wrote most of it.
“We were a little surprised,” said Zou Tao, director of the Tsinghua Tongheng Urban Planning and Design Institute in Beijing, who also contributed to Emerald Cities. “For more than 10 years we’ve been telling people to do this. We’re still getting used to it—and still figuring out how to make it happen in the real world.”

One of sub-Saharan Africa’s first light-rail lines, financed and built largely by China, opened in 2015. Carrying more than 100,000 passengers a day in packed cars, it has begun to transform the capital, allowing workers to reach jobs far from their homes. In Africa’s rapidly growing cities, sprawl is an epic challenge.
Chinese urbanization is at a turning point. The government aims to move nearly 300 million more people—almost equal to the entire U.S. population—into cities by 2030. China faces both a shortage of decent affordable housing and a housing bubble, because many people invest in apartments and keep them off the market, said Wang Hao, a planner who spent 20 years at the Chinese Academy of Urban Planning and Design. “Half the people have moved into the city; the other half can’t afford it,” she said. The government is trying, all at once, to design cities more humanely and sustainably and deflate the housing bubble without crashing the economy. No one is sure how to do all that, Wang said.
The key test may come in Xiongan, a 680-square-mile stretch of swampy land, including a heavily polluted lake, about 65 miles southwest of Beijing. In April 2017 President Xi Jinping announced, again to general surprise, that he wanted to build a new city there. Ultimately it could house five million people and relieve congestion and pollution in Beijing. Last summer, when I visited the site with He and a vanload of planners, all that had been built was a temporary city hall complex. Chinese tourists strolled the treelined streets. An autonomous shuttle bus circulated experimentally and emptily.
PUTRAJAYA, MALAYSIA The federal administrative center was planned in the 1990s to relieve congestion in nearby Kuala Lumpur. The new city has devoted more than a third of its area to green space—but walking distances are long.
Xi has declared Xiongan a project for the millennium. A video in the visitors center shows a low-rise, small-block, and extremely green city. It isn’t supposed to be completed until after 2035—an eternity by Chinese standards—but the master plan approved in December suggests it will be consistent with the Emerald Cities rule book. Calthorpe hopes to design part of it.
“We’re trying to solve all Chinese city problems,” said a landscape architect I met, a woman who preferred not to be identified. “We’re not sure we’re going to. This place will be an experiment.”
The next morning, He took me to see a more spontaneous experiment: a trendy arts district called 798, which lies in northeastern Beijing between the fourth and fifth rings. We waited until midmorning for the subway crowds to thin out—during the morning rush, the queues at some stations stretch all the way outside, because everyone is leaving one district to work in another. The nearest station to 798 was a few superblocks and about a mile away. Fortunately, dockless shared bikes have lately invaded the capital. We rented a couple and pedaled off.
It was a warm late-summer day, with a blue “meeting sky”—African heads of state were in town, He said, so the government had shut down smoke-spewing factories outside Beijing. The 798 district occupies the site of old factories that used to be outside the city too, before the city engulfed them. After the government closed the complex in the 1990s, artists began occupying the low brick buildings. Gradually a neighborhood of galleries, bars, and shops emerged. The blocks are small because they were laid out for a factory compound.
“This is very close to Portland,” He said, as we strolled the narrow streets. “We always take Portland as a good example.”
Planners face a big challenge: fighting the sprawl that has disconnected so many communities.
In an alley under a large, idle smokestack, we sipped cappuccinos, discussing the dramatic ideological change in Chinese urban planning. Undoing the effects of 30 years of superblock construction, He said, won’t be easy. “Given the scale and the economic challenges, it will take 20 to 30 years. You see points, small pieces here and there. We hope that over time, all the urban landscape will change.”
In the U.S. landscape too, islands of hope are emerging in the sea of sprawl.
Ellen Dunham-Jones, an architect and urban designer at Georgia Tech in Atlanta, one of the most sprawling cities on Earth, keeps a database of them. In 2009, when she and June Williamson of the City College of New York cowrote their book Retrofitting Suburbia, they reviewed around 80 cases of suburban spaces being transformed, mostly into something urban—that is, denser and more walkable. Today the number of projects in the database has grown to 1,500. Across the country, Dunham-Jones told me, developers are adding buildings mixing residential and retail to some 170 office parks. As online shopping kills hundreds of malls, she said, around 90 are in the process of “becoming the downtowns their suburbs never had.”
Market forces are driving the transition. The nuclear family for whom suburban subdivisions were envisioned is no longer the statistical norm; only a little over a quarter of all U.S. households consist of people with children. Young people are looking for an urban lifestyle, and so are many of the parents they left behind in the suburbs. In the little towns around Atlanta, as elsewhere in the U.S., Dunham-Jones said, “main streets were mostly killed off in the 1970s. Now that the malls are dying, those main streets are coming back.”
SHANGHAI, CHINA An elevated walkway allows pedestrians to survive the Mingzhu Roundabout in Pudong and to navigate among the widely spaced office buildings and malls. Roughly a quarter million Chinese die on the roads each year; more than half are pedestrians or cyclists.
In Duluth, Georgia, 25 miles northeast of Atlanta in Gwinnett County, I visited one. Gwinnett was farm country until sprawl hit like a tsunami, Chris McGahee, Duluth’s economic development director, told me. From 1970 to 2008, the county’s population ballooned from 72,000 to 770,000, Duluth’s from 1,800 to 25,000. “When you leave to go to college, you come back and can’t find anything you remember,” McGahee said. “Except in downtown Duluth, there’s a little string of eight buildings that are more than a hundred years old. For some reason, they survive.”
McGahee started work in October 2008, at the height of the financial crisis. Out of the pain grew opportunity. “What the recession did for us is make land affordable,” he said. Over the next few years the town managed to buy 35 acres around those eight buildings along the railroad tracks. The buildings were nothing special, just little brick relics from the late 19th century. But they had charm and emotional weight.
They’ve now become the nucleus of a restaurant district with a music venue that offers experiences people can’t get online. Around that Main Street, the town is working to have 2,500 units of housing within a 10-minute walk. Townhomes are selling out before they’re finished, McGahee said. He lives in one and walks to work at the monumental city hall, which faces a large green.
The most ambitious revitalization project in the Atlanta area is the BeltLine: an effort to breathe new life into a 22-mile loop of abandoned railway lines around the city center. Five segments of the loop, about a third of the total, are now a paved trail for walking and jogging, biking and skating.
“The economic story is a wild success,” said Ryan Gravel, who first envisioned the BeltLine in 1999 for his master’s in urban planning at Georgia Tech. The $500 million that Atlanta has invested in it has stimulated four billion dollars in development, Gravel said, mostly on the city’s east side. Where the Eastside Trail crosses Ponce de Leon Avenue, for example, a giant old Sears, Roebuck warehouse has become the Ponce City Market, a food hall, mall, and office complex. A Ford factory that once made Model T’s is now loft apartments.
But Gravel’s idea was that the BeltLine could bind the fragmented city more powerfully: It was meant to be a streetcar line as well, one that would spur economic development and affordable housing in the places that needed it most—the African-American neighborhoods in the south and west of the city. MARTA, the Atlanta transit authority, has built one small streetcar line and has a $2.7 billion expansion plan. But it has no plans to build the whole 22-mile loop anytime soon. Gravel worries that “the promise won’t ever be delivered.”
He grew up in Chamblee, a suburb to the northeast, “going to the mall, stuck in traffic on I-285,” he said. “Practically every year they added another lane.” Then in college he spent a year in Paris. He discovered a functioning subway and the joy of wandering the streets aimlessly. “I learned how to walk in Paris,” he said. He came back to Atlanta to be part of changing it.
From the Ponce City Market, we walked south to an old telephone factory, where Gravel plans to open a café and forum to bring people together to talk about the Atlanta they want. Joggers and cyclists and pedestrians streamed by us on the trail. The rail line had always been a physical barrier that separated neighborhoods; now it’s a place that connects people.
“That’s kind of beautiful,” Gravel said.
A century ago, as the Ford plant on Ponce de Leon was starting to churn out Model T’s, Atlanta was shooting outward along streetcar lines. Many major cities in the U.S. were doing the same, stretching tentacles of rail into the countryside and building villages around the stations. Until after World War II, Los Angeles had the world’s most extensive urban rail network, more than a thousand miles of track.
“That is what creates the urban form,” said Joe DiStefano, a longtime colleague of Calthorpe’s who runs the UrbanFootprint business. “Berkeley is a walkable place because the urban form was generated by the investment in a streetcar system.” Even in spread-out Los Angeles, most places were within walking distance of a transit stop, until the city and the country shifted, DiStefano said, “until the automobile made it possible for us to travel broader distances on our own—the automobile, and trillions of dollars of investment in the infrastructure to move it.”
Los Angeles became the paragon of car culture. But these days it’s trying to move out of that trap—back to the future. Since 2008, Los Angeles County voters have twice approved, by two-thirds majorities, half-cent hikes in the sales tax to pay for an extensive transit expansion—in part, no doubt, because they hope it will get other people off the freeway. “We have soul-crushing congestion,” said Therese McMillan, chief planning officer for Metro, the transit authority. The Expo light-rail line to Santa Monica was completed in 2016; the Purple subway line is being extended nine miles, from downtown to near UCLA; and a light-rail line is planned to the southeast—along an old streetcar right-of-way.
Transit alone can’t fix Los Angeles; ridership actually fell last year. “Driving’s too cheap, housing’s too expensive,” said Michael Manville, an urban planner at UCLA. People have to pay to ride transit, but not to drive the freeway or to park in most places. Meanwhile, an affordable-housing crisis brought on by gentrification and citizen resistance to multifamily housing pushes low-income people, the ones most likely to ride public transit, to the fringes of the metropolis, where public transit is sparse.
Change is happening: In Santa Monica I met one architect, Johannes Van Tilburg, who has designed 10,000 units of housing near transit lines in the past 15 years. But can the whole fabric of a sprawling city be changed?
“I think the answer is absolutely yes,” DiStefano said. It took us only 50 years to blow up a walkable urban form that had endured millennia, he said; we could undo that in another 50. DiStefano worked with Calthorpe on the El Camino thought experiment. “That corridor is Anywhere, U.S.A.,” he said. The same opportunity exists on strips around the country—the same opportunity to create walkable, connected cities to house a growing population, without cutting another tree or paving another mile.
Before Anywhere, U.S.A., is reimagined, however, it’s likely to be hit by the next explosive new technology. Self-driving cars should ultimately be safer than human-driven ones. Bombing along bumper to bumper in 60-mile-an-hour platoons, they may increase road capacity and reduce the space we devote to parking. But by the same logic, they could also dramatically increase the number of vehicle miles traveled, as robotic Uber and Lyft taxis deadhead around the metropolis 24/7, waiting for fares, and as personal-AV owners leave them spinning in traffic to go shopping. And consider, finally, the new impetus that robotic chauffeurs could inject into urban sprawl. If your car becomes a self-driving office or living room or bedroom, how far would you be willing to commute in it?
How about if your car were a plane? In a hangar south of San Jose, I got a glimpse of a future that may not be far off. The hangar belonged to a company called Kitty Hawk, and it contained four little aircraft with cheerful yellow fuselages. Each wing had six electric propellers pointed upward. Cora, as the plane is called, takes off like a helicopter and runs on battery power. It has two seats, and neither is for a pilot—Cora flies itself. A pilot on the ground monitors its progress, taking control remotely if necessary.
Former Virgin America CEO Fred Reid, who oversaw Cora until early this year, explained the rationale for self-flying planes. He began by showing me a video of that soul-crushing traffic in Los Angeles. “There’s no doubt in any thinking man’s or woman’s brain that this is not only going to happen, it has to happen,” he said. Kitty Hawk has a bunch of competitors.
Across the U.S., renewed desire for an urban lifestyle is sprinkling suburbia with new ‘downtowns.’
The initial market for Cora would be as an air taxi, Reid said. You’d arrive at LAX, say, and a Cora would whisk you a thousand feet above the traffic, flying a predetermined route. It would be relatively cheap, he said, closer to an Uber Black in price than to a helicopter. Being electric, it would be quiet and relatively green. Also, Reid added, “we try to make our planes pretty.” He pictures thousands in the skies above L.A.
I’d take one in a heartbeat, I realized.
But what will it be like, I asked Reid, to have thousands of these zipping around the skyline? You’re inventing a new technology that has just as much revolutionary potential as automobiles. What kind of world will it make?
“We’ll figure it out,” Reid said.
Maybe we will. But it might be wise to do some of the figuring first. We didn’t have to go completely nuts about cars, allowing them to become the tail that wagged the urban dog. We didn’t have to rip up all the streetcar lines. We didn’t have to forget that cities are for people—and we don’t need to do it again.
When Gehl started his career in 1960, Copenhagen was choked with cars too. Gehl began as an architect in the modernist tradition, designing the kinds of buildings that he now dismisses as “perfume bottles”—sculptural compositions rather than humanistic ones. But he changed course, and so did his city. Copenhagen has committed to becoming the world’s best city for pedestrians and cyclists. It’s working. Two-fifths of all commutes now are by bike.
The point is not that bikes are the answer; it’s that we can be thoughtful about the shape of our cities. “Waking up every morning and knowing that the city is a little bit better than it was yesterday—that’s very nice when you have children,” Gehl said. “Think about that … Your children have a better place to live, and your grandchildren have a better place to grow up than you could when you were young. I think that’s what it should be like.”
