What happens when a piano is combined with technology?

“Kids or anybody could learn how to play the piano really properly from the best musicians in the world,” said Mischa Dohler, composer and professor of Wireless Communications at King’s College London.

‘Could we digitize skills?’

Dohler’s aim is to build a database that records the movements of a piano player’s hands with the help of a special sensing glove that tracks every movement of the musician’s joints. Once the data is collected, a piano student can then wear another glove that can train the student’s hands.

“You could imagine this so-called exoskeleton that you can put on your hand. It will pressurize the hands and the joints, and will move it gently at the beginning, and nudge essentially the body into the right shape and in the right way of moving your hand,” Dohler said.

It is an example of what Dohler calls the “Internet of Skills” that he is demonstrating at the Optical Fiber Communication Conference and Exhibition in Los Angeles.

“We use digital today to negotiate for jobs. We use LinkedIn, emails, etc., but then to execute the work, we still need to drive. We need to fly. We need to walk. So I was thinking, ‘Could we virtualize it? Could we digitize skills?’”

Health care application

Another application for the “Internet of Skills” is health care.

Motivated by the Ebola crisis in Africa, Dohler is trying to develop a way for doctors to treat a patient thousands of miles away, especially in remote areas where medical skill is lacking, where virtual reality and low-cost technology can link the doctor and patient in a way never before possible.

“What I’m trying to do is first of all give the surgeons back the feeling of touch, so he feels what he does inside the body; and the second thing is, I want him to be able to have this console somewhere in another hospital. So the only thing we’re doing is the cable between the console and the patient and make it longer and make it an internet,” Dohler said.

It is only possible if large amounts of data can travel very quickly, more specifically, 10 milliseconds for action and reaction to occur. Companies are already developing hardware to move information faster.

Depends on data, speed

“It all came about with video. The way we view content today is very different from the way we viewed it before, and getting content to everybody, whether it’s on their iPhone or their android devices or on their PCs everywhere takes the underlying network,” said Eve Griliches, product line manager at Cisco Systems.

She said many new networks that transport and transmit growing amounts of data are being built by private networks.

“Everybody has a stake in the game now. Everybody has a stake,” she said. “And the beauty about getting the content to everybody, more so the other step, is as we’re opening up the networks and creating the sort of open source society in the networking area, it allows people to build on it,” Griliches added.

As technology continues to catch up with what the brain can imagine, Dohler envisions the “Internet of Skills” democratizing labor in about a decade, just as the internet has made knowledge available to all.

A message of resilience posted online in the wake of the London terrorist attack Wednesday was read in Parliament, it was mentioned on the BBC, and it went viral online.

Unfortunately, the hand written message, which appeared in a photo of a whiteboard commonly seen in the London Underground, was a hoax.

The message read: “All terrorists are politely reminded that THIS IS LONDON and whatever you do to us, we will drink tea and jolly well carry on. Thank you.”

One member of Parliament read the message to Prime Minister Theresa May, who then called the sign a “wonderful tribute” that “encapsulated everything everybody in this house has said today.”

An announcer on the BBC’s Radio 4 recited the sign’s message on the air, while other journalists and politicians shared the image online, The Washington Post reported.

Turns out the sign, which looked quite authentic, was created using one of the many sign generators available online.

Whiteboards are common in the London Underground, usually giving service information and occasionally displaying a joke or something meant to be inspirational.

The U.S. Central Intelligence Agency has technology capable of infecting “factory fresh” iPhones and has been bugging the devices since at least 2008, WikiLeaks claimed Thursday.

In a statement released on its website, the whistleblowing organization said the technology developed by the CIA’s Embedded Development Branch (EDB) was designed to be physically installed onto new iPhones.

“It is likely that many CIA physical access attacks have infected the targeted organization’s supply chain including by interdicting mail orders and other shipments [opening, infecting, and resending] leaving the United States or otherwise,” the statement read.

Another alleged CIA tool, exposed in the WikiLeaks release Thursday, has the ability to execute code from a USB stick while a Mac computer is still booting up, allowing a user to bypass firmware passwords and load the attack software.

Thursday’s release is the latest batch of documents published by WikiLeaks alleging to show espionage programs used by the U.S. spy agency.  A previous WikiLeaks release purported to expose a massive hacking program employed by the CIA.

Among the revelations in the previous release came accusations that the CIA possesses a library of hacking malware employed by other states, including Russia, that it can use to leave behind false “fingerprints” to cover up its exploits and mislead investigators.

A spokesman for the CIA said at the time the agency does not comment “on the authenticity of purported intelligence documents.”

Google Maps users will soon be able to broadcast their movements to friends and family — the latest test of how much privacy people are willing to sacrifice in an era of rampant sharing.

The location-monitoring feature will begin rolling out Wednesday in an update to the Google Maps mobile app, which is already installed on most of the world’s smartphones. It will also be available on personal computers.

Google believes the new tool will be a more convenient way for people to let someone know where they are without having to text or call them.  The Mountain View, California, company has set up the controls so individuals can decide with whom they want to share their whereabouts and for how long — anywhere from a few minutes to indefinitely.

But location sharing in one of the world’s most popular apps could cause friction in marriages and other relationships if one partner demands to know where the other is at all times. Similar tensions could arise if parents insist their teenagers turn on the location-sharing option before they go out.

Some share concerns

It could also be turned into a way to stalk someone entangled in an abusive relationship, warned Ruth Glenn, executive director for the National Coalition Against Domestic Violence. “It has the potential to be another tool in an abuser’s toolkit,” she said.

Similar tracking is already available on other apps; Glympse, founded by former Microsoft employees, has offered this function for years. Although it isn’t as wide-ranging, Apple also offers a tracking option called “Find My Friends” on its iPhone, iPad and Watch.

That’s one of the reasons Google isn’t expecting a lot of complaints about adding the option to Maps, especially since everyone can decide when to turn it on and who can monitor them.

“We don’t feel like we are changing the game,” said Jen Fitzpatrick, Google’s vice president of maps.

Tracking only a tap away

Maps users will be able to activate the location-sharing feature by tapping a button near the search bar and then picking a person from their contact list to text with the information. If the recipient doesn’t have the Google Maps app on their phone, it will text them a link to open the location on the map in a browser.

The settings also allow users to determine how long their movements can be tracked each time a location is shared. If no time limit is selected, Google will periodically send people email reminders that they’re still sharing their location, a step that Glenn said may help anyone who didn’t know an abusive partner was still following them.

The cost for individual homes in the U.S. to “go solar” has dropped by more than 60 percent over the last decade.

Those low costs helped convince more than a million Americans to install solar panels on their roofs.

Now schools are beginning to get in on the benefits. One of them is the school system in Fremont, Indiana.

The residents of this small town in America’s upper Midwest have always relied on the sun to warm their fields and draw tourists to their lakes. Now school superintendent William Stitt said they’re counting on it to power their schools.

“The technology has advanced so much in the last couple of years that it’s become more energy efficient, more cost effective for schools to get solar energy,” Stitt said.

Start-up cost

Construction of the solar project will cost $3 million. But when finished, it will completely power the elementary, middle and high school buildings. It may generate so much electricity, that the school will be able to sell some back to the power company at a profit.

The system will work through several rows of 3,000-4,000 panels each. They will be located in a special 2.5 hectare solar field behind the middle school.

The district has to lease the equipment from the local power company for 20 years, at a fixed rate.

But Kim Quick, facility director, said that even with that added cost, the schools should save money because the panels should last 40 years.

“[It] is going to cost us approximately the same amount we’re paying for utilities today. So that cost is never going to increase for the next 20 years,” Quick said. “So if the power company comes in next year and says, ‘We want to increase utilities 6 percent,’ we’re going to pay the same we’re paying today 20 years from now.”

Free electricity, eventually

In 20 years, the school district will own the equipment outright, meaning it won’t pay anything for electricity.

Since the panels are always “on,” Quick said the district will save additional money by banking the unused electricity that’s generated when school is not in session.

“These work year-round. Even in a full moon they will produce electricity,” he said.

Just 3 percent of the nation’s 125,000 schools use some form of solar energy. While not all can use solar power cost-effectively, a recent report by the Solar Foundation found that 72,000 US schools could save money with solar.

Schools could install panels on their roofs or elevate a field of panels over a parking lot. Those innovations would save most schools an average of $1 million over 30 years.

Educational component

Going solar also offers schools an educational component. It provides teachers opportunities to incorporate lessons in science, technology, engineering, and math into the curriculum.

All three schools in the Fremont system will have a live display module that kids can visit daily to learn how much energy is being used and saved.

If all goes according to plan, Fremont School District’s new solar field will be up and running by mid-summer. Superintendent Stitt is already looking further ahead.

“I’d love the community and the kids in 40 years to go, ‘Man, they made a great decision 40 years ago by creating this solar project!’ ” he said.

Google wants to make it easier for you to find answers and recommendations on smartphones without having to think about what to ask its search engine.

Its new feature, called “shortcuts,” will appear as a row of icons below the Google search box. Where now you’d have to ponder and then speak or type a request, the shortcuts will let you tap the icons to get the latest weather, movie times, sports scores, restaurant recommendations and other common requests.

The shortcuts will begin appearing Tuesday in updates to Google’s app for iPhones, Android phones and its mobile website. The Android app will also include various tools such as a currency converter, a language translator and an ATM locator, which you can also summon with a tap. Those tools may eventually make it to the iPhone as well, although Google says it doesn’t know when.

These shortcuts are the latest step in Google’s quest to turn its search engine into a secondary brain that anticipates people’s needs and desires. The search engine gleans these insights by analyzing your past requests and, when you allow it, tracking your location, a practice that periodically raises privacy concerns about Google’s power to create digital profiles of its users.

Based on the knowledge that Google already has accumulated, its shortcuts feature may already list your favorite sports teams or recommend nearby restaurants serving cuisines you prefer.

Adapting to audience

Shortcuts also show how Google’s search engine has been adapting to its audience, now that smartphones have become the primary way millions of people stay connected to the internet.

Since more than half of requests for Google’s search engine now come from smartphones, the Mountain View, California, company has adapted its services to smaller screens, touch keyboards and apps instead of websites.

Early in that process, Google tweaked its search engine to answer many requests with factual summaries at the top of its results page, a change from simply displaying a list of links to other websites. Voice-recognition technology also allows you to speak your request into a phone instead of typing it.

The transition is going well so far. Google’s revenue rose 20 percent last year to $89 billion, propelled by digital ads served up on its search engine, YouTube and Gmail. Although shortcuts won’t initially show ads after you tap them, Google typically sells marketing space if a feature or service becomes popular.

The enemy drone whined in the distance. The Interceptor, a drone-hunting machine from Silicon Valley startup Airspace Systems, slinked off its launch pad and dashed away in hot pursuit.

The hunter twisted through the air to avoid trees, homed in on its target, fired a Kevlar net to capture it, and then carried the rogue drone back to its base like a bald eagle with a kill.

Airspace is among some 70 companies working on counter-drone systems as small consumer and commercial drones proliferate. But unlike others, it aims to catch drones instead of disabling them or shooting them down.

A demonstration at Airspace headquarters in San Leandro, California, showed a compact aircraft just a few feet wide, yet capable of sophisticated, autonomous navigation and accurate targeting of a drone in motion.

It is still early days in the drone-defense business.

Security professionals both public and private worry about dangerous drones at military sites, airports, data centers, and public venues like baseball stadiums. But counter-measures carry risk, too.

For example, the U.S. Air Force recently tested experimental shotgun shells for shooting down drones. But if the drone carries a payload like a bomb or chemical weapon, it could still fall on its target.

Jamming the radio signals to the drone does not always work, either. Drones differ from “remote-controlled” aircraft because they can fly to pre-set coordinates autonomously. The fastest drones can reach 150 miles per hour (240 km), too quick for human pilots flying another drone to catch.

The technical challenge of safely stopping a dangerous drone appealed to Guy Bar-Nahum, one of the inventors of the Apple iPod and the engineering brains behind Airspace Systems.

“We are creating a very primitive brain of an insect, a dragonfly,” Bar-Nahum said. “It wakes up, sees the world and doesn’t really know where it is. But it has goals to capture the other drone, and it’s planning a path in the world and knows how to move through the world.”

The Interceptor must pack computing power and sophisticated software into that tiny drone brain. Unlike the emerging driverless car, it has to understand its environment without the benefit of an internet connection to a massive mapping database.

“My background is in physics, and it’s all about modeling the world” with math, Bar-Nahum said. “What we do in this lowly startup that looks to be a normal, military ‘take ’em down’ kind of company is build machines that can model the world.”

The business model is challenging too. Currently, only law enforcement officials have the authority to interfere with another drone’s flight. Regulations also require a certified pilot to stand ready to intervene in any commercial drone flight and keep a line-of-sight view of the aircraft.

Thus, Airspace Systems will not be selling its aircraft, but rather leasing a system — complete with operators and a mobile command center — to customers.

The New York Mets have an interest in using the system to protect Citi Field in New York City, according to Sterling VC, the venture capital arm of Sterling Equities, which owns the stadium and also invested in Airspace.

Detection and destruction

The danger from hostile drones became more clear in the last few months when the U.S. military said Islamic State fighters were using them to attack Iraqi troops in the battle over Mosul.

The military news site Defense One reported IS was using an array of consumer-style drones, including an agile quadcopter version for dropping explosives.

At least 70 companies worldwide are working on various types of counter-drone systems, said Mike Blades, aerospace and defense analyst with Frost & Sullivan.

San Francisco-based Dedrone, for example, has raised $28 million in venture capital and is focused on detecting drone incursions. It now has about 200 customers, according to CEO and co-founder Joerg Lamprecht. Some are car companies looking to protect new designs from the automotive press and others are data center owners looking to keep drones from damaging critical rooftop cooling systems.

“Most of the market is going to be detection, something like a burglar alarm,” Lamprecht said.

DroneShield, an Australian company, also makes a detection system and has developed a prototype electronic jamming gun to ground a drone.

Airspace, backed by $5 million from Shasta Ventures and Sterling VC, hopes to bring its drone-capture system to market as early as this summer.

But Airspace’s approach has limitations. Chief among them: The Interceptor catches one drone at a time. To defend against multiple drones, Airspace must launch multiple machines.

“The swarm of drones is going to be the threat,” said Blades.

Beyond that, catching drones incurs expense and complication when simpler measures might do. Dedrone’s Lamprecht gives an example from a German customer that makes cars.

At its test track, the customer wanted to protect new car designs from drones’ prying eyes. When Dedrone detects an intrusion, the car’s driver hits a dashboard button to fire a fog bomb to obscure the car.

But James Bond-style diversions, or even forcing a drone down, may prove insufficient if a craft is hovering above a crowd with something dangerous, like an explosive or poison. In such a situation, capturing and carrying away the enemy drone may be the best option, even if it is complex and expensive.

For Airspace, perfecting a drone-hunting machine than can see — and chase — on its own is not as crazy as it may seem.

“This is an old ambition. You can read about it in Jules Verne or Aldous Huxley,” said Bar-Nahum. “That’s why autonomous movement is the next decade for me.”

Apple is cutting prices on two iPad models and introducing red iPhones, but the company held back on updating its higher-end iPad Pro tablets.

A much-speculated 10.5-inch iPad Pro didn’t materialize, nor did new versions of existing sizes in the Pro lineup, which is aimed at businesses and creative professionals. The new devices are mostly refreshes of existing models. Apple unveiled them through press releases Tuesday rather than a staged event, as it typically does for bigger product releases.

 

The iPad updates come as the tablet market continues to decline, after a few years of rapid growth. According to IDC, tablet shipments fell 20 percent to 53 million worldwide in the final three months of 2016, compared with the same period in 2015.

The new lineup

The iPad Air 2 is replaced by a new model simply called the iPad. It retains a 9.7-inch screen, but gains a little weight and thickness. The display is brighter and the processor faster. Its price starts at $329 for 32 gigabytes of storage, down from $399. The standard-size iPad is now cheaper than the smaller Mini model.

 

The 7.9-inch iPad Mini 4 now comes with 128 gigabytes of storage starting at $399, rather than $499 before. Apple is eliminating the 32-gigabyte model, which used to sell for $399. Nothing else is changing.

Apple is also releasing a red edition of the iPhone 7 and 7 Plus; for each phone sold, Apple is donating an unspecified amount to HIV and AIDS programs. And Apple is doubling the storage on the smaller iPhone SE while keeping the $399 starting price.

 

The new iPad Mini 4 is available right away, while the standard-size iPad comes out next week, with orders to begin Friday. The new iPhone SE comes out Friday, while the red iPhones are expected by the end of the month, with advance orders beginning Friday.

The missing device

IDC analyst Jorge Vela had high hopes for a 10.5-inch iPad. He said such a size might have offered room for a better keyboard, compared with the 9.7-inch iPad Pro, and it wouldn’t have been as bulky as the 12.9-inch version.

And Apple typically sparks consumer interest when it has new sizes and designs, Vela said, as seen by a jump in sales following the introduction of larger iPhones in 2014 (iPhone sales have since dropped.) Vela said a 10.5-inch version might have been enough for existing iPad owners to upgrade.

A 10.5-inch version may still come this year, closer to the holiday shopping season, along with updates to existing Pro sizes.

Jackdaw Research analyst Jan Dawson said Tuesday’s announcement makes it “even clearer that there are two very distinct iPad tiers now — the iPad Pro and the basic iPads. The iPad Pros will likely continue to get all the best new features, while the basic iPad will get occasional updates and new features a little later than the Pros, lagging a generation or two behind.”

The processor in the new standard-size iPad, for instance, is akin to what’s in the iPhone 6S from 2015. The Mini’s processor is even older.

Down, but not out

In the last three months of 2016, iPhones generated 10 times the revenue as iPads. Unit sales of iPads fell 19 percent from the previous year. Yet Apple CEO Tim Cook has expressed optimism because many people were buying iPads for the first time, indicating that the market had yet to reach saturation, the point at which everyone who wants a particular product already has one.

 

Dawson agrees that the number of tablet owners is still growing, even if overall sales are declining because people aren’t upgrading often. He said the new $329 price for the 9.7-inch iPad should help spur sales. New 9.7-inch models have previously cost at least $499.

Far from holding a clearance sale, Vela said Apple is merely taking advantage of lower prices for older components. And Apple might be able to preserve higher profit margins by pushing people into a model with four times the storage, or 128 gigabytes; the extra storage costs Apple far less than the extra $100 that model sells for, Vela said.

Challengers

Apple remains the market leader, accounting for about a quarter of all tablets shipped in the fourth quarter, according to IDC.

Samsung beat Apple to a tablet announcement by nearly a month, though Samsung’s Android-based Galaxy Tab S3 doesn’t actually start selling until this Friday, for $600.

Vela doesn’t consider it a serious threat to Apple. Even though the Tab S3 is more in line with iPad Pros in quality, Vela said people tend to buy Samsung tablets as media-consumption devices, something they can do with the cheaper iPads.

Samsung also has two Windows 10 tablets coming. Called the Galaxy Book, the Windows devices are more likely to challenge Microsoft’s Surface than iPads. Microsoft is due for a refresh of its Surface Pro tablet, last updated in October 2015.

Twitter suspended more than 376,000 accounts in the second half of 2016, most of which it said were promoting terrorism.

Most of the accounts, 74 percent, were removed by proprietary software, the company said in its latest transparency report. The software reportedly determines a terrorism related account through how it behaves, rather than what it posts, saying the accounts have “distinctive behavior.”

Two percent of the accounts were suspended by various government requests, according to Twitter.

The number of suspensions is three times more than the social media site deleted in the last half of 2015.

In total, the company says it suspended 636,280 accounts from August 1, 2015 to December 31, 2016.

The report comes as Facebook and Google are wrestling with how to prevent objectionable content from their sites.

An organization affiliated with Google is offering tools that news organizations and election-related sites can use to protect themselves from hacking.

Jigsaw, a research arm of Google parent company Alphabet Inc., says that free and fair elections depend on access to information. . To ensure such access, Jigsaw says, sites for news, human rights and election monitoring need to be protected from cyberattacks.

Jigsaw’s suite of tools, called Protect Your Election, is mostly a repackaging of existing tools:

– Project Shield will help websites guard against denial-of-service attacks, in which hackers flood sites with so much traffic that legitimate visitors can’t get through. Users of Project Shield will be tapping technology and servers that Google already uses to protect its own sites from such attacks.

– Password Alert is software that people can add to Chrome browsers to warn them when they try to enter their Google password on another site, often a sign of a phishing attempt.

– 2-Step Verification helps beef up security beyond passwords by requiring a second access code, such as a text sent to a verified cellphone. Though Jigsaw directs users to turn this on for Google accounts, most major rivals offer similar protections, too.

“This is as much an occasion to have a conversation about digital security as it is putting all the tools in one place,” Jigsaw spokesman Dan Keyserling said.

While the tools can be useful to a variety of groups and individuals, Jigsaw says it is focusing on elections because cyberattacks often increase against news organizations and election information sites around election time. In particular, Jigsaw wants to help sites deploy the tools ahead of the French presidential elections, which begin April 23.

The tools are free, though Project Shield is limited to news organizations, individual journalists, human-rights groups and election-monitoring organizations.

It’s not known whether the tools might have prevented some of the high-profile attacks in the past, including the theft of emails from Democratic Party computers during the 2016 U.S. presidential campaign. The tools do not directly address such break-ins, but they could help guard against password stealing, a common precursor to break-ins.

Cutting-edge technologies — from drones to data collected by taxi drivers — are becoming key weapons in the global battle to improve land rights and fight poverty, experts said Monday.

Advances in earth observation, digital connectivity and computing power provide an array of information, from detailed topographical maps to transportation use, that was previously unimaginable, geospatial experts said at a World Bank Conference on Land and Poverty.

The information collected can be instrumental to helping establish property records and land titling systems in countries where there is no formal ownership or land-use documentation.

Drones help map Africa

Survey-mapping drones may look like toys but are powerful machines having a huge impact on land-use planning in Africa, said Edward Anderson, a senior World Bank disaster management expert.

High-quality, high-resolution images taken by drones in Zanzibar identified nearly 2,000 new buildings in one 12-month period alone, he said.

The mapping exercise, budgeted at $2 million in 2005, was completed at a tenth of the price by local university students operating the small, light, unmanned drones, Anderson said.

“Coastal zones are developing and urbanizing so quickly, waterside areas are being developed into hotels, residential properties,” he said.

“Until now, there was no way of quantifying this change and making comparisons,” Anderson said.

Massive growth exposed

While more than 87 percent of the land mass of Europe is mapped at a local level, such maps exist for only about 3 percent of the entire African continent, he said.

A project using drones in Mauritania, a country twice the size of France but with a population of less than four million, has allowed authorities to document the massive growth of cities such as its capital, Nouakchott, said University of Arizona professor Mamadou Baro.

Originally established in 1959 with fewer than 5,000 residents, Nouakchott is the largest city in the Sahara and home to more than 1.5 million people.

“This is placing huge pressure on social infrastructure and chaos in the development of the city,” Baro said. “Drones are very helpful in attempting to manage and track this kind of enormous growth.”

Private companies that collect data as part of their businesses are being encouraged to share with state planning authorities as well, said Holly Krambeck, a World Bank transport planning expert.

Taxi drivers track roads 

GPS data collected by taxi drivers is helping to design plans for infrastructure and roads in countries such as Brazil and in North Africa, she said.

The shared data comes through agreements with technology companies such as Grab that operates ride-hailing and logistics services apps in Southeast Asia, including the Philippines, Thailand, Vietnam and Indonesia.

Using technology can also help identify new sources of tax revenue, experts said.

In Tanzania, improved mapping data revealed that up to two-thirds of properties in secondary cities were not on the tax rolls, they said.

Zander Dejah, 25, pays $1,900 a month rent to live in a downtown San Francisco house with at least 40 other people, many of whom sleep in bunk beds.

Dejah is a resident of The Negev, a communal living space that styles itself as a home for millennial tech workers to brainstorm ideas, write code and create apps, even if they have to share toilets and bathrooms with dozens of others.

Houses like The Negev, located in a neighborhood known as “SoMa” or South of Market, have cropped up around San Francisco as an influx of young professionals, many of whom are tech workers, have faced the city’s notoriously high rents and apartment shortages. It has three floors and roughly 50 rooms, filled with bunk beds, beer bottles and laptops, according to residents.

Dejah, born and raised in New York, graduated last year with a degree in computer science and math from McGill University.

Unemployed, he moved to California six months ago and found his  room at The Negev on Craigslist.

“I thought New York was expensive,” said Dejah, who quickly landed a job as a virtual reality engineer at consulting firm moBack. “It’s basically an extension of college. We sort of live in a frat house.”

The home is certainly filled with parties on weekends, but the residents make sure to sit down every Sunday for a communal dinner, akin to a traditional family gathering.

While some say communal housing provides a solution for many first-time workers fresh out of college, such housing also has created its share of controversy. Housing advocates have complained that this new dorm-like style of living has pushed up rents and forced longtime residents to move out.

Alon Gutman, who co-founded a company called The Negev and began leasing the building on Sixth Street in 2014, said, “We have never made somebody move out of that building,” adding that his tenants pay 30 percent to 50 percent less than others in the neighborhood.

“We are trying to solve the housing crisis and increase density in a positive way.”

The Negev company runs nine communal properties, three of which are in San Francisco. The others are in Austin, Texas, and Oakland, California.

The Negev properties, generally in run-down, low-income neighborhoods, are restructured to accommodate a large number of tenants, Gutman explained.

Sarah Sherburn-Zimmer, executive director of the Housing Rights Committee of San Francisco, said housing problems have arisen because occupants leave buildings being converted to communal homes and cannot afford to move back in or the space is no longer suitable for them.

“The Negev house takes affordable housing and makes it unaffordable,” said Sherburn-Zimmer. “All they’ve done is take away housing from people who had it and loved it and pushed them out to make a quick buck.”

Kumar Srikantappa, 31, who also pays $1,900 a month for a single room at The Negev, said he chose the house because of the social experience. After eight months there, the software engineer for Oracle Corp said he would soon be ready to live elsewhere.

“I met a bunch of friends, and I just want to move on to another location and into a bigger place,” he said. “It’s time.”
