CNN is reporting on "CityTree", a unique 10-foot tall mobile installation which removes pollutants from the air." An anonymous reader quotes their report:
Berlin-based Green City Solutions claims its invention has the environmental benefit of up to 275 actual trees. But the CityTree isn't, in fact, a tree at all -- it's a moss culture. "Moss cultures have a much larger leaf surface area than any other plant. That means we can capture more pollutants," said Zhengliang Wu, co-founder of Green City Solutions.
The huge surfaces of moss installed in each tree can remove dust, nitrogen dioxide and ozone gases from the air. The installation is autonomous and requires very little maintenance: solar panels provide electricity, while rainwater is collected into a reservoir and then pumped into the soil... "We also have pollution sensors inside the installation, which help monitor the local air quality and tell us how efficient the tree is." Wu said. Its creators say that each CityTree is able to absorb around 250 grams of particulate matter a day and contributes to the capture of greenhouse gases by removing 240 metric tons of CO2 a year... Wu also argued that the CityTree is just one piece of a larger puzzle. "Our ultimate goal is to incorporate technology from the CityTree into existing buildings," he said.
So far they've installed 20 CityTrees -- each of which costs about $25,000.Read Replies (0)

Cushman & Wakefield, one of the world's largest real estate firms, launched a new report identifying America's top tech cities. An anonymous reader quotes their report:
Washington, DC has emerged as the promising tech city center after San Jose (Silicon Valley) and San Francisco... A dominating hub for life sciences and government, Washington, DC also serves as a significant outpost for tech companies seeking proximity to policymakers as well as for burgeoning cyber-security investment. The top 25 tech cities were determined by analyzing the concentration of factors such as talent, capital, and growth opportunity -- the key ingredients that comprise a tech stew. The heartiest of these tech epicenters are: 1. San Jose, CA (Silicon Valley); 2. San Francisco, CA; 3. Washington, DC; 4. Boston/Cambridge, MA; and 5. Raleigh/Durham/Chapel Hill, NC...
Report co-author and Regional Director, Northwest U.S. Research at Cushman & Wakefield, in San Francisco, Robert Sammons, said that while it was not surprising to see San Jose (Silicon Valley) and San Francisco continue to dominate, that mass-transit issues and escalating housing costs in those areas have fanned a tech spillover into secondary markets such as Austin (no. 7), Denver (no. 8), San Diego (no. 9), and Salt Lake City (no. 24)... Mr. Sammons cited cost-of-living in Seattle (no. 6) as a lingering issue, somewhat mitigated by a recent uptick in residential development that's outpacing San Francisco's, as well as mass transit challenges.
There's also several cities in the Midwest among the top tech cities, including Madison, Wisconsin (no. 10), Minneapolis/St. Paul, Minnesota (no. 11), Indianapolis, Indiana (no. 23), and Nashville, Tennessee (no. 25).Read Replies (0)

"I have the seriously growing suspicion that AI is coming for us programmers and IT experts faster than we might want to admit," writes long-time Slashdot reader Qbertino. So he's contemplating a career change -- and wondering what AI work is out there now, and how can he move into it?
Is anything popping up in the industry and AI hype? (And what are these positions called, what do they precisely do, and what are the skills needed to do them?) I suspect something like an "AI Architect", planning AI setups and clearly defining the boundaries of what the AI is supposed to do and explore.
Then I presume the requirements for something like an "AI Maintainer" and/or "AI Trainer" which would probably resemble something like an admin of a big data storage, looking at statistics and making educated decisions on which "AI Training Paths" the AI should continue to explore to gain the skill required and deciding when the "AI" is ready to be let go on to the task... And what about Tensor Flow? Should I toy around with it or are we past that stage already and will others do AI setup and installation better than me before I know how this thing really works...?
Is there a degree program, or other paths to skill and knowledge, for a programmer who's convinced that "AI is today what the web was in 1993"? And if AI of the future ends up tied to specific providers -- AI as a service -- then are there specific vendors he should be focusing on (besides Google?) Leave your best suggestions in the comments. How can programmers move into AI jobs?Read Replies (0)

An anonymous reader quotes the New York Times:
Last week, President Trump announced that the United States would withdraw from the Paris climate agreement. But it will take more than one speech to pull out: Under the rules of the deal, which the White House says it will follow, the earliest any country can leave is November 4, 2020. That means the United States will remain a party to the accord for nearly all of Mr. Trump's current term... Nov. 4, 2019 is the earliest date that the United States can submit a written notice to the United Nations that it is withdrawing from the Paris deal -- exactly three years after it came into force. As soon as that happens, the United States can leave the accord in exactly one year... If a new president enters the White House on Jan. 20, 2021, he or she could easily submit a written notice to the United Nations that the United States would like to rejoin the Paris accord. Within 30 days, the United States could re-enter the agreement and submit a new pledge for how the country plans to tackle climate change.
The article also acknowledges "a growing coalition of states, cities and companies that are pledging to do as much as they can to meet the United States' climate goals on their own."Read Replies (0)

An anonymous reader quotes BleepingComputer: Verelox, a provider of dedicated KVM and VPS servers based in The Hague, Netherlands, suffered a catastrophic outage after a former administrator deleted all customer data and wiped most of the company's servers. Details of what exactly happened aren't available, but according to posts on various web hosting forums [1, 2, 3], the incident appears to have taken place Thursday, when users couldn't access their servers or the company's website.
Verelox's homepage came back online earlier Friday, but the website was plastered with a grim message informing users of the ex-admin's actions. Following the incident, the hosting provider decided to take the rest of its network offline and focus on recovering customer data. Verelox staff don't believe they can recover all data. Saturday night the web site was advising customers that the network and hosting services "will be back this week with security updates," adding that "current customers who are still interested in our services will receive compensation."Read Replies (0)

Salon recently talked to Jeffrey Buchanan, who two years ago co-founded a labor rights group "that highlights the plight of security officers, food-service workers, janitors and shuttle-bus drivers in the region." An anonymous reader quotes their report:
The situation among Silicon Valley's low-wage contract workers has become so perilous that in January, thousands of security guards working at immensely profitable companies like Facebook and Cisco followed the shuttle-bus drivers and voted to unionize in an effort to collectively bargain for higher wages and better benefits. The upcoming labor contract negotiations between the roughly 3,000 security guards (represented by SEIU United Service Workers West) and their employers is one of the biggest developments in Silicon Valley labor organizing to happen this year. Buchanan says there's also a broader push this year to get tech companies to be proactive in ensuring these workers can make ends meet, even if these companies have to pay more for the services they procure...
A paper published last year by University of California at Santa Cruz researchers Chris Brenner and Kyle Neering estimates between 19,000 and 39,000 contracted service workers are employed in the Valley at any given time... An additional 78,000 workers are at risk of becoming contract employees, according to the study, a number which includes administrative assistants, sales representatives and medium-wage computer programmers. This is part of a larger societal shift in which salaried workers are converted to contractors -- a transition that benefits business owners, in that they don't have to pay benefits and can hire and fire contractors at will.
Buchanan's group represents contractors typically earning "as little as $20,000 a year." But Salon's headline argues that "programmers may be next" in the drive to organize contractors.Read Replies (0)

"Astronomers have confirmed that the Wow! signal, thought to be the most promising detection by SETI of alien life, was actually caused by a comet," writes schwit1. New Atlas reports:
Last year, a group of researchers from the Center of Planetary Science proposed a new hypothesis that argued a comet might be the culprit. The frequency could be caused by the hydrogen cloud they carry, and the fact that they move accounts for why it seemingly disappeared. Two comets, named 266/P Christensen and P/2008 Y2 (Gibbs), happened to be transiting through that region of space when the Wow! signal was detected, but they weren't discovered until after 2006. To test the hypothesis, the team made 200 radio spectrum observations between November 2016 and February 2017. Sure enough, 266/P Christensen was found to emit radio waves at a frequency of 1,420 MHz, and to double check, the researchers moved their radio telescope by one degree. As expected, the signal vanished, and only returned when the telescope was trained back on the comet.Read Replies (0)

Adam West, star of the 1960s TV series Batman, has died at age 88. An anonymous reader shares a memory of that time the 53-year-old actor wrote an op-ed for a 1982 issue of Videogame and Computer Gaming Illustrated.
"I've been playing with computers longer than most," West wrote on page 6. [PDF] "I had onboard computers in Robinson Crusoe on Mars, having learned in an episode of TV's The Outer Limits that you can't survive on the Red Planet without them. Then, of course, I was up to my cowl in computers as television's Batman... In 1966, when the series began its three season run, all of that was science fiction. Computers were playthings of the researchers at MIT... Today, a lot of the apparatus we had in Batman -- dressed, of course, in less imposing names -- is fact. And we're lucky this is so."
West called videogames "an ideal means to broaden the imaginations of young people," saying the medium "can expand our awareness of the world as it is, was, or might be. The medium is still in its infancy, but read this again in a few years and see if this prediction hasn't come true: as videogaming grows, we will grow."
My favorite story is how West was cast as Batman after the show's producer spotted his performance as super-spy Agent Q in a commercial for Nestle Quik. And CNN also remembers that "later in life, West made appearances on the animated series 'Family Guy' as Mayor Adam West, the oddball leader of Quahog, Rhode Island."Read Replies (0)

An anonymous reader writes:
86 cancer patients were enrolled in a trial of a drug that helps the immune system attack tumors. Though they had different kinds of tumor -- pancreas, prostate, uterus or bone -- they all shared a genetic mutation that disrupts their cells' ability to fix damaged DNA, found in 4% of all cancer patients. But tumors vanished and didn't return for 18 patients in the study, reports the New York Times, while 66 more patients "had their tumors shrink substantially and stabilize, instead of continuing to grow." The drug trial results were "so striking that the Food and Drug Administration already has approved the drug, pembrolizumab, brand name Keytruda, for patients whose cancers arise from the same genetic abnormality. It is the first time a drug has been approved for use against tumors that share a certain genetic profile, whatever their location in the body."
The researchers say that just in the U.S. there are 60,000 new patients every year who could benefit from the new drug.Read Replies (0)

An anonymous reader quotes CNBC:
The so-called "big five" -- Apple , Alphabet Class A shares, Microsoft , Facebook and Amazon -- lost more than $97.5 billion in market value between the close on Thursday and the close on Friday, according to FactSet, dragging the Nasdaq to its worst week of the year. Shares of Apple fell nearly 4 percent on Friday, while the other four companies fell more than 3 percent. For most of the day, only 3 stocks in the S&P 500 tech sector were in the green: IBM , Teradata and Western Union . Apple, Facebook, Amazon, Netflix, and Alphabet all traded more than 2 times their 30-day average volume... "They're just plain overbought," said David Bahnsen founder, managing director and chief investment officer of The Bahnsen Group, a private wealth management firm. "They are extremely stretched from a valuation standpoint."
CNN notes the drop occurred "after a Goldman Sachs analyst questioned this year's run-up in the industry's five biggest names." They also added that "The top five techs today account for 13% of the market value weighting in the S&P 500, even though they are only 1% of the companies in the index."Read Replies (0)
