What is your take on functional programming and related technologies (i.e. lambdas and streams)? Is it our salvation? Is it merely another useful design pattern? Or is it a technological dead-end?
Python creator Guido van Rossum has said most programmers aren't used to functional languages, and when he answered Slashdot reader questions in 2013 said the only functional language he knew much about was Haskell, and "any language less popular than Haskell surely has very little practical value." He even added "I also don't think that the current crop of functional languages is ready for mainstream."

An anonymous reader quotes MIT Technology Review:
A group of Australian marine scientists believe that altering clouds might offer one of the best hopes for saving the Great Barrier Reef. For the last six months, researchers at the Sydney Institute of Marine Science and the University of Sydney School of Geosciences have been meeting regularly to explore the possibility of making low-lying clouds off the northeastern coast of Australia more reflective in order to cool the waters surrounding the world's biggest coral reef system...
Last year, as El Nino events cranked up ocean temperatures, at least 20% of the reef died and more than 90% of it was damaged. The Australian researchers took a hard look at a number of potential ways to preserve the reefs. But at this point, making clouds more reflective looks like the most feasible way to protect an ecosystem that stretches across more than 130,000 square miles, says Daniel Harrison, a postdoctoral research associate with the Ocean Technology Group at the University of Sydney. Cloud brightening is the only thing we've identified that's scalable, sensible, and relatively environmentally benign," he says... Next month, he plans to start computer climate modeling to explore whether cloud brightening could make a big enough temperature difference to help.
They're collaborating with Silicon Valley's Marine Cloud Brightening Project, which has spent the last seven years "developing a nozzle that they believe can spray salt particles of just the right size and quantity to alter the clouds. They're attempting to raise several million dollars to build full-scale sprayers." The article describes them as "one of several research groups that have started to explore whether cloud brightening, generally discussed as a potential tool to alter the climate as a whole, could be applied in more targeted ways."Read Replies (0)

Nicholas Carr's book The Shallows: What the Internet Is Doing to Our Brains was a finalist for the 2011 Pulitzer Prize. Now an anonymous Slashdot reader reports on Carr's newest warning:
It seems obvious: The more we learn about other people, the more we'll come to like them. The assumption underpins our deep-seated belief that communication networks, from the telephone system to Facebook, will help create social harmony. But what if the opposite is true? In a Boston Globe article, Nicholas Carr presents evidence showing that as we get more information about other people, we tend to like them less, not more. Through a phenomenon called "dissimilarity cascades," we place greater stress on personal and cultural differences than on similarities, and the bias strengthens as information accumulates. "Proximity makes differences stand out," he writes. The phenomenon intensifies online, where people are rewarded for sharing endless information about themselves. What the research indicates, warns Carr, is that the spread of social media is more likely to create social strife than social harmony.
The article concludes by opposing the idea that "If we get the engineering right, our better angels will triumph. It's a pleasant thought, but it's a fantasy... Technology is an amplifier. It magnifies our best traits, and it magnifies our worst. What it doesn't do is make us better people. That's a job we can't offload on machines."Read Replies (0)

theodp quotes today's New York Times profile of Uber CEO Travis Kalanick:
For months, Mr. Kalanick had pulled a fast one on Apple by directing his employees to help camouflage the ride-hailing app from Apple's engineers. The reason? So Apple would not find out that Uber had secretly been tracking iPhones even after its app had been deleted from the devices, violating Apple's privacy guidelines.
Uber told TechCrunch this afternoon that it still uses a form of this device fingerprinting, saying they need a way to identify those devices which committed fraud in the past -- especially in China, where Uber drivers used stolen iPhones to request dozens of rides from themselves to increase their pay rate. It's been modified to comply with Apple's rules, and "We absolutely do not track individual users or their location if they've deleted the app..." an Uber spokesperson said. "Being able to recognize known bad actors when they try to get back onto our network is an important security measure for both Uber and our users."
The article offers a longer biography of Kalanick, who dropped out of UCLA in 1998 to start a peer-to-peer music-sharing service named Scour. (The service eventually declared bankruptcy after being sued for $250 billion for alleged copyright infringement.) Desperately trying to save his next company, Kalanick "took the tax dollars from employee paychecks -- which are supposed to be withheld and sent to the Internal Revenue Service," according to the Times, "and reinvested the money into the start-up, even as friends and advisers warned him the action was potentially illegal." The money eventually reached the IRS as he "staved off bankruptcy for a second time by raising another round of funding." But the article ultimately argues that Kalanick's drive to win in life "has led to a pattern of risk-taking that has put his ride-hailing company on the brink of implosion."Read Replies (0)

White hat hackers "are in very high demand," says PwC's director of cyber investigation and breach response, in a New York Post article titled "Companies are paying millions to get hacked -- on purpose." An anonymous reader quotes their report:
HackerOne, a San Francisco-based "vulnerability coordination and bug bounty platform," reports that it has some 800 corporate customers who paid out more than $15 million in bonuses to white-hat hackers since its founding in 2012. Most of that bounty was paid in the past two years, as companies have become more aware of their cyber vulnerabilities. Clients that have used the platform include General Motors, Uber, Twitter, Starbucks and even the US Department of Defense.
Google paid $3 million last year through its own bounty program, according to HackerOne's CEO Marten Micko, who touts his company's "turn-key" solution -- a platform which now offers the services of 100,000 ethical (and vetted) hackers. "With a diverse group, all types of vulnerabilities can be found," Micko told TechRepublic. "This is a corollary to the 'given enough eyeballs' wisdom... they find them faster than other solutions, the hunting is ongoing and not happening at just one time, and the cost is a tenth of what it would be with other methods." And one of the platform's white hat hackers has already earned over $600,000 in just two years.Read Replies (0)

Startup Eternime, founded by MIT fellow Marius Ursache, is still working on "immortal avatars" that, after your death, will continue interacting with your loves ones from beyond the grave. An anonymous reader quotes CNET:
Give Eternime access to your social media profiles and the startup's algorithms will scrape your posts and interactions to build a profile... The algorithms will study your memories and mannerisms. They'll learn how to be "you"... Eternime was announced in 2014 after Ursache developed the idea during the MIT Entrepreneurship Development Program. He wasn't entirely sure if he should develop the project further and wanted to get a sense of public reaction.
In the first four days, 3,000 people signed up at Eterni.me, the company's website, for a private beta. Then, Urasche received an email from a man dying of terminal cancer. "Eternime, he wrote, was the last chance to leave something behind for friends and family," Urasche told me. "That was the moment I decided that this was something worth dedicating my life to"... Since 2014, the Eternime website has largely been silent, although it continues to take names of people who want to test the service. Ursache says the Eternime team has been refining the product over the last two years, testing features, figuring out what will work and what won't.
"The private beta test is ongoing," according to the article, "and Ursache says the feedback has been positive." But unfortunately, the service still isn't operational yet.Read Replies (0)

"Comcast's customer service may actually be improving," writes an Oregon newspaper. An anonymous reader quotes their report:
In the second year of Comcast's broad customer service overhaul, complaints to Oregon cable regulators are down 25%. They've also declined 40% since 2014. Complaints are falling nationally, too, according to the highly regarded American Customer Satisfaction Index. Its most recent report showed a surge in Comcast subscriber satisfaction... Two years ago, Comcast made Oregon the test bed for its customer service push, responding both to disparaging headlines and the prospect of growing competition from other telecom companies and from streaming video services.
The company is adding Apple-style retail stores around the metro area and introduced innovations to help consumers understand what they're paying for and when technicians will arrive for service calls. It's rolling out new tools nationally to help them improve their home Wi-Fi, and diagnosing problems before customers call to complain... For example, if several subscribers in the same neighborhood use the company's tool for testing internet speeds, that triggers an alert at Comcast to look for a problem in the local network. The company redesigned its bills to make it clearer what customers subscribe to, and what it costs, in hopes of reducing confusion and calls. And Comcast has a robust social media presence, fielding complaints on Twitter.
The article points out that Comcast's satisfaction scores are still below-average for cable TV providers, "and well below the median among internet service providers. And that's a low bar -- the telecom sector is among the most complained about under ACSI's rankings." Their figures show that the only ISPs in America with a lower score for customer satisfaction are Cox Communications, Time Warner Cable, and MediaCom.Read Replies (0)

An anonymous reader quotes Caltech's announcement about the results of a study funded by NASA and the Department of Energy:
During the early 2000s, environmental scientists studying methane emissions noticed something unexpected: the global concentrations of atmospheric methane -- which had increased for decades, driven by methane emissions from fossil fuels and agriculture -- inexplicably leveled off. The methane levels remained stable for a few years, then started rising again in 2007... New modeling by researchers at Caltech and Harvard University suggests that methane emissions might not have increased dramatically in 2007 after all. Instead, the most likely explanation has less to do with methane emissions and more to do with changes in the availability of the hydroxyl radical, which breaks down methane in the atmosphere... If global levels of hydroxyl decrease, global methane concentrations will increase -- even if methane emissions remain constant, the researchers say...
Tracking decadal trends in both methane and hydroxyl, Christian Frankenberg and his colleagues noted that fluctuations in hydroxyl concentrations correlated strongly with fluctuations in methane... "Think of the atmosphere like a kitchen sink with the faucet running," Frankenberg explains. "When the water level inside the sink rises, that can mean that you've opened up the faucet more. Or it can mean that the drain is blocking up. You have to look at both."
So what's changing the level of hydroxl in the atmosphere? The researchers say they have no idea.Read Replies (0)

Archive.org argues robots.txt files are geared toward search engines, and now plans instead to represent the web "as it really was, and is, from a user's perspective."
We have also seen an upsurge of the use of robots.txt files to remove entire domains from search engines when they transition from a live web site into a parked domain, which has historically also removed the entire domain from view in the Wayback Machine... We receive inquiries and complaints on these "disappeared" sites almost daily."
In response, Slashdot reader Lauren Weinstein writes:
We can stipulate at the outset that the venerable Internet Archive and its associated systems like Wayback Machine have done a lot of good for many years -- for example by providing chronological archives of websites who have chosen to participate in their efforts. But now, it appears that the Internet Archive has joined the dark side of the Internet, by announcing that they will no longer honor the access control requests of any websites.
He's wondering what will happen when "a flood of other players decide that they must emulate the Internet Archive's dismal reasoning to remain competitive," adding that if sys-admins start blocking spiders with web server configuration directives, other unrelated sites could become "collateral damage." But BoingBoing is calling it "an excellent decision... a splendid reminder that nothing published on the web is ever meaningfully private, and will always go on your permanent record." So what do Slashdot's readers think? Should Archive.org ignore robots.txt directives and cache everything?Read Replies (0)

An anonymous reader writes:
Microsoft is still encouraging businesses to rent their Office software, according to TechRadar. "In a bid to further persuade users of the standalone versions of Office to shift over to a cloud subscription (Office 365), Microsoft has announced that those who made a one-off purchase of an Office product will no longer get access to the business flavours of OneDrive and Skype come the end of the decade." PC World explains that in reality this affects very few users. "If you've been saving all of your Excel spreadsheets into your OneDrive for Business cloud, you'll need to download and move them over to a personal subscription -- or pony up for Office 365, as Microsoft really wants you to do."
Microsoft is claiming that when customers connect to Office 365 services using a legacy version of Office, "they're not enjoying all that the service has to offer. The IT security and reliability benefits and end user experiences in the apps is limited to the features shipped at a point in time. To ensure that customers are getting the most out of their Office 365 subscription, we are updating our system requirements." And in another blog post, they're almost daring people to switch to Linux. "Providing over three years advance notice for this change to Office 365 system requirements for client connectivity gives you time to review your long-term desktop strategy, budget and plan for any change to your environment."
In a follow-up comment, Microsoft's Alistair Speirs explained that "There is still an option to get monthly desktop updates, but we are changing the 3x a year update channel to be 2x a year to align closer to Windows 10 update model. We are trying to strike the right balance between agile, ship-when-ready updates and enterprise needs of predictability, reliability and advanced notice to validate and prepare."Read Replies (0)

MIT Technology Review reports:
David Mitchell, a lanky, soft-spoken atmospheric physicist, believes frigid clouds in the upper troposphere may offer one of our best fallback plans for combating climate change... Fleets of large drones would crisscross the upper latitudes of the globe during winter months, sprinkling the skies with tons of extremely fine dust-like materials every year. If Mitchell is right, this would produce larger ice crystals than normal, creating thinner cirrus clouds that dissipate faster. "That would allow more radiation into space, cooling the earth," Mitchell says...
Increasingly grim climate projections have convinced a growing number of scientists it's time to start conducting experiments to find out what might work. In addition, an impressive list of institutions including Harvard University, the Carnegie Council, and the University of California, Los Angeles, have recently established research initiatives... By this time next year, Harvard professors David Keith and Frank Keutsch hope to launch a high-altitude balloon from a site in Tucson, Arizona. This will mark the beginning of a research project to explore the feasibility and risks of an approach known as solar radiation management. The basic idea is that spraying materials into the stratosphere could help reflect more heat back into space, mimicking a natural cooling phenomenon that occurs after volcanoes blast tens of millions of tons of sulfur dioxide into the sky.
"I don't really know what the answer is," says a former associate director at Lawrence Livermore National Laboratory. "But I do believe we need to keep saying what the truth is, and the truth is, we might need it."Read Replies (0)

Long-time reader Esther Schindler writes:
Innovation occurs outside the Bay Area, New York, Boston, and Austin. So why is it so hard for a startup to get attention and acquire venture capital? Steve Case and Kara Swisher discussed this never-ending-topic recently, such as the fact 78% of U.S. venture capital last year went to just three states: California, New York, and Massachusetts. Case sees a "third wave" of venture capital funding and through his VC firm is investing in startups based outside major tech centers.
But, points out Stealthmode's Francine Hardaway, if you're in Boise or Baltimore you don't have to wait for Case to come to town. She shares advice about what's worked in other startup communities, focusing on the #YesPhx efforts.

Network World reports that customers are being notified "on a rolling basis... Once customers are notified, they are presented with a personal take-action date that is 30 days from the original notification." But even after that date, verizon.net email addresses can be revived using AOL Mail. "Over the years we've realized that there are more capable email platforms out there," Verizon concedes.
