Recycling Plants Start Installing Trash-Spotting AI Systems (yahoo.com) 60

The world's biggest builder of recycling plants has teamed with a startup to install AI-powered systems for sorting recycling, reports the Washington Post. And now over the next few years, "The companies plan to retrofit thousands of recycling facilities around the world with computers that can analyze and identify every item that passes through a waste plant, they said Wednesday." "[S]orted" recyclables, particularly plastic, wind up contaminated with other forms of trash, according to Lokendra Pal, a professor of sustainable materials engineering at North Carolina State University... [W]aste plants don't catch everything. [AI startup] Greyparrot has already installed over 100 of its AI trash spotters in about 50 sorting facilities around the world, and [co-founder Ambarish] Mitra said as much as 30 percent of potentially recyclable material winds up getting lumped in with the trash that's headed for the landfill. Failing to recycle means companies have to make more things from scratch, including a lot of plastic from fossil fuels. Also, more waste ends up in landfills and incinerators, which belch greenhouse gases into the atmosphere and pollute their surroundings.

Mitra said putting Greyparrot's AI tools in thousands of waste plants around the world can raise the percentage of glass, plastic, metal and paper that makes it to recycling facilities. "If we can move the needle by even 5 to 10 percent, that would be a phenomenal outcome on a planetary basis for greenhouse gas emissions and environmental impact," he said. Cutting contamination would make recycled materials more valuable and raise the chances that companies would use them to make new products, according to Reck. "If the AI and the robots potentially helped to increase the quality of the recycling stream, that's huge," she said...

Greyparrot's device is, basically, a set of visual and infrared cameras hooked up to a computer, which monitors trash as it passes by on a conveyor belt and labels it under 70 categories, from loose bottle caps (not recyclable!) to books (sometimes recyclable!) to aluminum cans (recyclable!). Waste plants could connect these AI systems to sorting robots to help them separate trash from recyclables more accurately. They could also use the AI as a quality control system to measure how well they're sorting trash from recyclables. That could help plant managers tinker with their assembly lines to recover more recyclables, or verify that a bundle of recyclables is free of contaminants, which would allow them to sell for a higher price.

GreyParrot's co-founder said their trash-spotting computers "could one day help regulators crack down on companies that produce tsunamis of non-recyclable packaging," according to the article.

"The AI systems are so accurate, he said, that they can identify the brands on individual items. 'There could be insights that make them more accountable for ... the commitments they made to the public or to shareholders,' he said."

Why Didn't Sidecar's Flex Pricing Work? 190

Bennett Haselton writes Sidecar is a little-known alternative to Lyft and Uber, deployed in only ten cities so far, which lets drivers set their own prices to undercut other ride-sharing services. Given that most amateur drivers would be willing to give someone a ride for far less than the rider would be willing to pay, why didn't the flex-pricing option take off?

Virtual DVDs, Revisited 147

Bennett Haselton writes: "In March I asked why Netflix doesn't offer their rental DVD service in 'virtual DVD' form -- where you can 'check out' a fixed number of 'virtual DVDs' per month, just as you would with their physical DVDs by mail, but by accessing the 'virtual DVDs' in streaming format so that you could watch them on a phone or a tablet or a laptop without a DVD drive. My argument was that this is an interesting, non-trivial question, because it seems Netflix and (by proxy) the studios are leaving cash on the table by not offering this as an option to DVD-challenged users. I thought some commenters' responses raised questions that were worth delving into further." Read on for the rest of Bennett's thoughts.

Bug Bounties Don't Help If Bugs Never Run Out 235

Bennett Haselton writes: "I was an early advocate of companies offering cash prizes to researchers who found security holes in their products, so that the vulnerabilities can be fixed before the bad guys exploited them. I still believe that prize programs can make a product safer under certain conditions. But I had naively overlooked that under an alternate set of assumptions, you might find that not only do cash prizes not make the product any safer, but that nothing makes the product any safer — you might as well not bother fixing certain security holes at all, whether they were found through a prize program or not."

Are DVDs Inconvenient On Purpose? 490

Slashdot contributor Bennett Haselton writes: "Why do Netflix and a few other companies keep the DVD format alive, when streaming is more convenient for almost all users? The answer is not obvious, but my best theory is that it has to do with what economists call price discrimination. Netflix is still the cheapest legal way to watch a dozen recent releases every month — but only if you're willing to put up with those clunky DVDs." Read on for the rest of Bennett's thoughts.

Comment Malevolence or Mediocrity? (Score 1) 56

Two roughly similar problems over 5 years might lead you to suppose they did this out of malevolence. But let's look at the value proposition. Bing Lord 1: Let's censor all Chines language results to please our Mainland Chinese overlords! Bing Lord 2: Good idea! They'll appreciate it if we solve a problem we already solved for them. Bing Lord 1: Yes! In the meantime we'll piss off everybody else who gets wind of it, and get lots of free publicity from the ensuing shit storm! Both: We are incredibly smart! It seems more likely to me that this is the result of bungling at one or more points in the chain from design to infrastructure, probably caused by managerial bungling.

I haven't hung out on Slashdot for many years, so I come to the site with expectations shaped by years of use from the 90s to 2006 or so. The current site isn't too jarring from that point of view. The changes are mostly obvious improvements. Most important for me, the community is still recognizable. The same paranoid ranting and trolling, with occasionally very interesting/insightful/funny and useful contributions from a few posters, whose comments get modded up effectively. I think the motto, "News for Nerds" still applies, and that's comforting. (Although Slashdot seldom breaks a story, by design, it's a great place to get nerdy reactions to the news.)

The new design is familiar looking. It's the sort of thing you'll see on Google+ or many Wordpress blogs.Headlines are bigger. The in-your-face topic drop-down is startling, but effective. Assuming the sidebars are still customizable, I don't have an argument with the esthetics of the design. But it does affect my workflow to a slight degree. When I'm browsing Slashdot, I scan down the headlines until I see something that interests me. I immediately open the link to the original story in a new tab. If the article interests me, I keep the tab open, and click through to the comments in yet another tab. If I don't like the article, I close the tab and go back to scanning headlines. Since the link to the fine article isn't in the headline, the beta site forces me to open the submission just to get to TFA. It's a minor quibble, but I don't like change. ( :)

I'd like to add a couple more notes. First of all, thanks for providing this mechanism and for listening. Despite the paranoid trolls, It's clear you are listening. Also, I can't imagine you aren't eating your own dog food on this one. Trolls that accuse you of this without a shred of evidence are annoying. (They wouldn't be trolls if they didn't try to be annoying. Right.) One more thing, I'm concerned by your statement that you are trying to make the site more accessible to less technical users. Though I totally understand you trying to grow your audience, you still have "News for Nerds" in your title. It's always a challenge to balance a friendly interface with a nerdy "give me information now" sensibility. Without irony, I wish you good luck in your efforts to achieve that.

Bennett Haselton: Google+ To Gmail Controversy Missing the Point 244

Bennett Haselton writes "Google created controversy by announcing that Google+ users will now be able to send email to Gmail users even without having those Gmail users' email addresses. I think this debate misses the point, because it's unlikely to create a deluge of unsolicited email to Gmail users, as long as Google can throttle outgoing messages from Google+ users and terminate abusive accounts. The real controversy should be over the fact that Google+ users can search a public database of the names of all Gmail users in the first place. And limiting the ability of Google+ users to write to those Gmail accounts, won't do anything to address that." Read below to see what Bennett has to say.

Should Facebook 'Likes' Count As Commercial Endorsements? 189

Slashdot contributor Bennett Haselton writes: "Facebook settled out of court over displaying ads that told you which of your friends had 'liked' a product or service, and another lawsuit is currently pending over the use of minors' pictures specifically in similar ads. (Not to be confused with another recently filed lawsuit alleging that Facebook converts private messages into public 'likes'.) Google+ tried to limit its liability by only showing the faces of users over 18 when showing which friends 'like' a page. I'm all for more privacy for social networking users, and if it's true that Facebook has been silently marking users as publicly 'liking' a page because they mentioned the page in a private message, the plaintiff's lawyers ought to clean them out for that one. But in cases where you willingly and knowingly 'liked' a page, Facebook and Google+ ought to be able to tell that to your friends in advertisements, without being sued for it."

From the article: 'The Portable Document Format (PDF) is one of the file formats of choice commonly used in today's enterprises, since it's widely deployed across different operating systems. But on a down-side this format has also known vulnerabilites which are exploited in the wild. Secure Computing's Anti-Malware Research Labs spotted a new and yet unknown exploit toolkit which exclusively targets Adobe's PDF format.'"
