AI-Enhanced Weed-Killing Robots Frighten Pesticide Industry (reuters.com) 73

Rick Schumann writes: A Swiss company called ecoRobotix is betting the agricultural industry will be willing to welcome their solar-powered weed-killing autonomous robot, in an effort to reduce the use of herbicides by up to a factor of 20 and perhaps even eliminate the need for herbicide-resistant GMO crops entirely.

The 'see-and-spray' robot goes from plant to plant, visually differentiating the actual crops and weeds, and squirting the weeds selectively and precisely with weed killer, as opposed to the current technique of using large quantities of weed killer like Monsantos' Roundup to spray entire crops.

Weeds are already becoming resistant to such glyphosate-based herbicides after "more than 20 years of near-ubiquitous use," reports Reuters. (The head of one pesticide company's science division concedes that "That was probably a once-in-a-lifetime product.") But AI-based precision spraying "could mean established herbicides whose effect has worn off on some weeds could be used successfully in more potent, targeted doses."

Meanwhile, another Silicon Valley startup has built a machine using on-board cameras to distinguish weeds from crops -- and was recently acquired by the John Deere tractor company. Reuters calls these companies the "new breed of AI weeders that investors say could disrupt the $100 billion pesticides and seeds industry."

Companies Are Using California Homes As Batteries To Power the Grid (qz.com) 93

"Companies like Tesla and SunRun are starting to bid on utility contracts that would allow them to string together dozens or hundreds of systems that act as an enormous reserve to balance the flow of electricity on the grid," reports Quartz. "Doing so would accelerate the grid's transformation from 20th century hub-and-spoke architecture to a transmission network moving electricity among thousands or millions of customers who generate and store their own power." From the report: In theory, networked home-solar-and-battery systems, acting in coordination over a single geographical area, could replace things like natural gas "peaker" plants need to help support the grid on a moment's notice. But it's an open question whether it makes financial sense. Kamath says renewable mandates could keep home solar-storage solutions for the grid going for a while, but the idea will have to prove itself on the market, perhaps by aggregating large areas, if it wants to seriously compete with existing energy assets.

SunRun told investors in 2017 that its pilot programs suggest it could competitively generate $2,000 worth of services by managing electricity flow back to the grid. The company has recently dropped its combative stance with utilities dragging their feet on accepting home solar. Instead, it's pursuing cooperation with the utilities now, in hopes of selling them home-based power. That would allow it grab a chunk of the billions being spent on modernizing the grid. "We don't want to be in a position of building two competing infrastructures," SunRun's Jurich said.

Google Zooms By Amazon In Smart Speaker Shipments, Report Says (arstechnica.com) 25

A new report released this week says that Google has surpassed Amazon in global smart speaker shipments in the first quarter of 2018. "[Research firm Canalys] says Google shipped 3.2 million Google Home and Home Mini speakers over the course of the quarter," reports Ars Technica. "Amazon, meanwhile, is said to have shipped 2.5 million Echo speakers." From the report: According to the report, Google jumped from taking 19.3 percent of smart speaker shipments in Q1 2017 to 36.2 percent this past quarter. Amazon accounted for a whopping 79.6 percent of shipments in the year-ago quarter but fell to 27.7 percent in Q1 2018, the report says. Now, it appears the Home has reached a point of parity with the Echo; this report would mark the first time Google has overtaken Amazon in total shipments. Canalys credits Google's rise in part to retailers and channel operators "prioritizing" the Home over the Echo, given that Amazon is one of its biggest competitors in retail at large. A couple of caveats: neither Amazon nor Google breaks out quarterly sales figures for each device family, so Canalys' figures likely aren't 100-percent exact. It's also worth noting that "shipments" are not the same as "sales," so it's possible that deals and discounts on the devices have affected the figures to an extent.

Robot Worries Could Cause a 50,000-Worker Strike in Las Vegas (technologyreview.com) 310

Thousands of unionized hotel and casino workers in Las Vegas are ready to go on strike for the first time in more than three decades. From a report: Members of the Culinary Union, who work in many of the city's biggest casinos, have voted to approve a strike unless a deal is reached soon. Some background: On June 1, the contracts of 50,000 union workers expire, making them eligible to strike. Employees range from bartenders to guest room attendants. The last casino worker strike, in 1984, lasted 67 days and cost more than $1 million a day. Why? Higher wages, naturally. But the workers are also looking for better job security, especially from robots. "We support innovations that improve jobs, but we oppose automation when it only destroys jobs," says Geoconda Arguello-Kline, secretary-treasurer for the Culinary Union. "Our industry must innovate without losing the human touch."

Apple Blocks Steam's Plan To Extend Its Video Games To iPhones (reuters.com) 184

Citing "business conflicts," Apple has blocked Steam's plans to distribute PC-based video games to iPhones. It's "a sign that Apple is serious about protecting its ability to take a cut of digital purchases made inside games on its mobile devices," reports Reuters. From the report: Steam, the dominant online store for downloaded games played on Windows PCs, had planned to release a free mobile phone app called Steam Link so that gamers could continue playing on their mobile phones while away from their desktop machines. But Apple has rejected the app, blocking its release, according to a statement from Steam's parent company, the Bellevue, Washington-based Valve. Steam did not give a precise reason for the App Store denials, saying only that Apple cited "business conflicts with app guidelines." But the conflict likely centers on what are known as in-app purchases or micro-transactions, in which gamers can spend small sums of money inside games to buy tokens, extra lives or others so-called digital goods. Lombardi said Steam disabled purchasing its iOS app but did not elaborate on how the change was made. Many analysts believe Apple could lose revenue if they allow Steam's app, which is essentially a store-within-a-store. "Apple takes a 30 percent cut of such purchases made within apps distributed through its App Store," Reuters notes. "[T]hose purchases are among the primary drivers of revenue in Apple's services business."

Samsung Must Pay Apple $539 Million For Infringing iPhone Design Patents, Jury Finds (cnet.com) 141

Samsung must pay Apple $539 million for infringing five patents with Android phones it sold in 2010 and 2011, a jury has found in a legal fight that dates back seven years. "The unanimous decision, in the U.S. District Court in San Jose in the heart of Silicon Valley, is just about halfway between what the two largest mobile phone makers had sought in a high-profile case that reaches back to 2011," reports CNET. From the report: The bulk of the damages payment, $533,316,606, was for infringing three Apple design patents. The remaining $5,325,050 was for infringing two utility patents. Samsung already had been found to infringe the patents, but this trial determined some of the damages. The jury's rationale isn't clear, but the figure is high enough to help cement the importance of design patents in the tech industry. Even though they only describe cosmetic elements of a product, they clearly can have a lot of value.

Samsung showed its displeasure and indicated the fight isn't over. "Today's decision flies in the face of a unanimous Supreme Court ruling in favor of Samsung on the scope of design patent damages. We will consider all options to obtain an outcome that does not hinder creativity and fair competition for all companies and consumers," Samsung said.

Android Creator Puts Essential Up For Sale, Cancels Next Phone (bloomberg.com) 51

Bloomberg reports that Andy Rubin's Essential Products business is considering selling itself and has canceled development of a new smartphone. The news comes several months after numerous reports suggested that the Essential Phone's sales were tepid. From the report: The startup has hired Credit Suisse Group AG to advise on a potential sale and has received interest from at least one suitor, the people said. Essential is now actively shopping itself to potential suitors, one of the people said. The startup, part of Rubin's incubator Playground Global, has raised about $300 million from several investors, including Amazon, Tencent, and Redpoint Ventures. It was valued at $900 million to $1 billion about a year ago, according to an analysis by Equidate, which runs a market for private company stock.

The startup has spent more than $100 million on developing its first products, about a third of the money it raised to build the company, the people said. Current discussions are focused on a sale of the entire company, including its patent portfolio, hardware products like the original smartphone, an upcoming smart home device and a camera attachment for the phone. Essential's engineering talent, which includes those hired from Apple and Alphabet's Google, would likely be part of a deal. The company hasn't yet made a final decision on a sale, the people said.

Internal Documents Show Apple Knew the iPhone 6 Would Bend (vice.com) 127

In 2014, multiple users reported that their iPhone 6 and 6 Plus handsets were bending under pressure, such as when they were kept in a pocket. As a byproduct of this issue, the touchscreen's internal hardware was also susceptible to losing its connection to the phone's logic board. It turns out, Apple was aware that this could happen. Motherboard: Apple's internal tests found that the iPhone 6 and iPhone 6 Plus are significantly more likely to bend than the iPhone 5S, according to information made public in a recent court filing obtained by Motherboard. Publicly, Apple has never said that the phones have a bending problem, and maintains that position, despite these models commonly being plagued with "touch disease," a flaw that causes the touchscreen to work intermittently that the repair community say is a result of bending associated with normal use. The information is contained in internal Apple documents filed under seal in a class-action lawsuit that alleges Apple misled customers about touch disease. The documents remain under seal, but US District Court judge Lucy Koh made some of the information from them public in a recent opinion in the case. The company found that the iPhone 6 is 3.3 times more likely to bend than the iPhone 5s, and the iPhone 6 Plus is 7.2 times more likely to bend than the iPhone 5s, according to the documents. Koh wrote that "one of the major concerns Apple identified prior to launching the iPhones was that they were 'likely to bend more easily when compared to previous generations.'"

Qualcomm Announces Snapdragon 710 Platform For Midrange Android Phones (anandtech.com) 31

An anonymous reader quotes a report from AnandTech: Today Qualcomm announces a new entry to the Snapdragon lineup with the first 700-series SoC platform. The Snapdragon 710 is a direct successor to the Snapdragon 660 but comes with a new branding more worthy of the increased performance characteristics of the SoC. The big IP blocks found on the Snapdragon 710 are very much derivatives of what's found on the flagship Snapdragon 845. On the CPU side we see the same 2.2GHz maximum clock on the big cores, but the Kryo 360 Cortex A75 based CPUs are microarchitectural upgrade over last year's A72 based Kryo 260. The little cores are also based on the newer Cortex A55's and are clocked at up to 1.7GHz. The performance improvements are quoted as an overall 20% uplift in SPECint2000 and 25% faster performance in Octane and Kraken versus the SD660. The SoC now also uses the new system cache first introduced in the Snapdragon 845 -- although I'm expecting a smaller, yet unconfirmed 1MB size in the SD710. The 700-series SoC platform sports the new 600 series Adreno GPUs. They have an expected frequency of around 750MHz and up to 35% higher performance versus the Adreno 512 in the SD660.

"In terms of connectivity the new SoC implements an X15 modem which is capable of UE Category 15 in the downstream with up to 800Mbps in 4x carrier aggregation and up to UE Category 7 in the upload with up to 2x CA and 256 QAM," reports AnandTech. "The new chipset now also offers 2x2 802.11ac digital backend for Wi-Fi -- however it'll still need an external discrete analog RF frontend."

Google and LG Unveil World's Highest-Resolution OLED On-Glass VR Display (androidauthority.com) 53

A couple months ago, Road to VR reported that Google and LG were planning to reveal the "world's highest-resolution OLED on-glass display" for virtual-reality headsets on May 22nd. Well, that day has arrived and the two companies unveiled that very display. Android Authority reports: As expected, the 4.3-inch OLED 18MP display has a resolution of 4,800 x 3,840. The display has a pixel density of 1,443PPI and a 120Hz refresh rate. Google and LG referred to it as the "world's highest-resolution OLED on-glass display." For comparison's sake, the HTC Vive has two 3.6-inch displays with resolutions of 1,200 x 1,080. The higher-end HTC Vive Pro has two 3.5-inch displays with resolutions of 1,600 x 1,440. The Vive Pro maxes out at 615PPI, making this new LG panel about 57% better than HTC's best offering. However, there's already one display that's better than anything on offer, and that's your own vision. A person with great vision sees in an estimated resolution of 9,600 x 9,000 with a PPI density of 2,183. In other words, this new display from Google and LG is about half as good as our own eyes. Unfortunately, there are no plans to use them in any consumer products yet. Google rep Carlin Verri told 9to5Google that the companies started this project to push the industry forward.

Razer Slims Down Blade, Debuts MacOS-Compatible eGPU Enclosure (arstechnica.com) 40

An anonymous reader quotes a report from Ars Technica: Today, Razer debuted big updates to its Razer Blade laptop, focusing on design and performance to usher the gaming notebook into 2018. While the new Blade still looks unmistakably "Razer," its design has changed dramatically for the better. Razer upped the screen size from 14 inches to 15.6 inches, reducing the surrounding bezels to just 4.9mm so that the device fits in with the other nearly bezel-less ultrabooks popular today. Razer is offering 1080p 60Hz or 144Hz panels, along with a 4K touchscreen option as well. The larger display panel makes the laptop slightly heavier than its predecessor, and it's a bit wider overall, too (4.7 pounds and 9.3 inches, respectively). However, the slimmer bezels, sharper edges, and aluminum unibody make the new Razer Blade look like a clear upgrade from the previous model.

Another new addition to the Razer lineup is the Core X, a Thunderbolt 3 external graphics enclosure with space for large, three-slot wide graphics cards. The Core X joins the Core V2 graphics enclosure as one of Razer's solutions for gamers who want to add desktop-like graphics power to their laptops -- and it's more affordable than the V2 as well. While it's a bit stockier than Razer's existing enclosure, the Core X has an aluminum body with open vents to properly handle heat, regardless of the task at hand. The Core X connects to a compatible notebook through one Thunderbolt 3 port, providing eGPU access and 100W of power thanks to its 650 ATX power supply. It's both cheaper and seemingly easier to use than the V2, but that comes with some compromises: the Core X doesn't have Chroma lighting, and it lacks USB and Ethernet ports.
Some other specs of the new Blade include a Intel Core i7-8750H processor, Nvidia GTX 1060 or 1070 with Max-Q graphics, up to 32GB of RAM, up to 2TB of PCIe-based SSD, and 80Whr battery. There are three USB-A 3.1 ports, one proprietary charging port, one Thunderbolt 3 port, a Mini DisplayPort, and an HDMI port.

Creeping Lava Now Threatens Major Hawaiian Power Plant (gizmodo.com) 68

An anonymous reader quotes a report from Gizmodo: Molten lava from Hawaii's Kilauea volcano has entered the grounds of Puna Geothermal Venture, a geothermal power plant that provides about 25 percent of the Big Island's power. The 38 Megawatt Puna Geothermal Venture (PGV) power plant, which is located in the east rift zone of the Kilauea volcano, was shut down soon after the eruptions began on May 3. Yesterday, lava from Fissure 22 came to within 820 feet (250 meters) of the plant's nearest well pad before stalling, as Reuters reports. Overnight, workers managed to cap the 11th and final well at the facility in anticipation of the lava eventually reaching the facility, and to prevent the uncontrollable release of toxic gases. Mercifully, the lava flow stopped at a ridge near the PGV plant, but as the events of the past two weeks have shown, Mount Kilauea is in an extremely volatile state. The HCCD said Fissure 22 is producing most of the lava feeding the flows, so the situation near the power plant remains precarious.

The Toughest (And Weakest) Phones Currently On the Market (tomsguide.com) 112

New submitter Daneel Olivaw R. shares a report from Tom's Guide: To measure each phone's toughness, [Tom's Guide] dropped it from both 4 and 6 feet onto wood and concrete. After each test, we recorded the damage to the phone. If a phone was rendered unusable -- the screen totally shattered, for instance -- then we stopped dropping it. [More details on the testing process can be found here.] Each drop was worth a maximum of 5 points; if a phone made it through all of the rounds unscathed, it would earn 35 points. The more severe the damage per drop was, the more points were deducted. If a phone was rendered unusable after a given drop, it would earn no points, and would not undergo any subsequent test. In total, there were seven tests. [...] If a phone died in the 6-foot edge drop, it was penalized an extra 10 percent. If it died in the 6-foot face drop, it was penalized 5 percent. And if it died when dropped into the toilet, it lost 2.5 percent. We then divided the total score by 3.5, to put it on a 10-point scale. Here are the scores of each device:

Motorola Moto Z2 Force - Toughness score: 8.5/10
LG X Venture - Toughness score: 6.6/10
Apple iPhone X - Toughness score: 6.2/10
LG V30 - Toughness score: 6/10
Samsung Galaxy S9 - Toughness score: 6/10
Motorola Moto G5 Plus - Toughness score: 5.1/10
Apple iPhone 8 - Toughness score: 4.9/10
Samsung Galaxy Note 8 - Toughness score: 4.3/10
OnePlus 5T - Toughness score: 4.3/10
Huawei Mate 10 Pro - Toughness score: 4.3/10
Google Pixel 2 XL - Toughness score: 4.3/10
iPhone SE - Toughness score: 3.9/10

Tesla Model 3 Falls Short of Consumer Reports Recommendation (cnbc.com) 295

Consumer Reports published their review of the Tesla Model 3 today. The product review site liked the vehicle's range of the battery and agile handling, but had issues with braking, controls, and ride quality. Overall, it failed to get a recommendation. CNBC highlights the key shortfalls: "Our testers also found flaws -- big flaws -- such as long stopping distances in our emergency braking test and difficult-to-use controls," said a review in the publication. In particular, the car's stopping distance of 152 feet from a speed of 60 miles per hour was slower than any of its contemporaries, including the Ford F-150, a full-size pickup. The location of almost all of Tesla's controls on a touchscreen and the vehicle's ride quality were also factors in the group's decision. Tesla issued a statement in response to Consumer Reports' stopping distance claim: "Tesla's own testing has found braking distances with an average of 133 feet when conducting the 60-0 mph stops using the 18-inch Michelin all season tire and as low as 126 feet with all tires currently available. Stopping distance results are affected by variables such as road surface, weather conditions, tire temperature, brake conditioning, outside temperature, and past driving behavior that may have affected the brake system. Unlike other vehicles, Tesla is uniquely positioned to address more corner cases over time through over-the-air software updates, and it continually does so to improve factors such as stopping distance."

Sony Is Done Working For Peanuts in the Hardware Business, New CEO To Detail Shift Away From Gadgets (bloomberg.com) 132

Kenichiro Yoshida, who took over as chief executive officer in April, is set to unveil a three-year plan on Tuesday that embraces Sony's growing reliance on income from gaming subscriptions and entertainment. From a report: The transition is already happening: even though the company sold fewer hardware products such as televisions, digital cameras, smartphones and PlayStation consoles in the year through March, it was able to post record operating profit. It's a tectonic shift for a company built on manufacturing prowess. Sony popularized transistor radios, gave the world portable music with the Walkman and its TVs were considered top-of-the-line for decades. With the rise of Chinese manufacturing, making and selling gadgets has become a business with razor-thin profit margins. Investors have applauded the transformation that's been under way since Kazuo Hirai took over as CEO in 2012, with the shares climbing more than five-fold amid a turnaround.

Scientists Transfer Memory Between Snails (scientificamerican.com) 92

An anonymous reader quotes a report from Scientific American: UCLA neuroscientists reported Monday that they have transferred a memory from one animal to another via injections of RNA, a startling result that challenges the widely held view of where and how memories are stored in the brain. The finding from the lab of David Glanzman hints at the potential for new RNA-based treatments to one day restore lost memories and, if correct, could shake up the field of memory and learning. The researchers extracted RNA from the nervous systems of snails that had been shocked and injected the material into unshocked snails. RNA's primary role is to serve as a messenger inside cells, carrying protein-making instructions from its cousin DNA. But when this RNA was injected, these naive snails withdrew their siphons for extended periods of time after a soft touch. Control snails that received injections of RNA from snails that had not received shocks did not withdraw their siphons for as long.

Glanzman's group went further, showing that Aplysia sensory neurons in Petri dishes were more excitable, as they tend to be after being shocked, if they were exposed to RNA from shocked snails. Exposure to RNA from snails that had never been shocked did not cause the cells to become more excitable. The results, said Glanzman, suggest that memories may be stored within the nucleus of neurons, where RNA is synthesized and can act on DNA to turn genes on and off. He said he thought memory storage involved these epigenetic changes -- changes in the activity of genes and not in the DNA sequences that make up those genes -- that are mediated by RNA. This view challenges the widely held notion that memories are stored by enhancing synaptic connections between neurons. Rather, Glanzman sees synaptic changes that occur during memory formation as flowing from the information that the RNA is carrying.
The study has been published in the journal eNeuro.

The Verge Goes Hands-On With the 'Wildly Ambitious' RED Hydrogen One Smartphone (theverge.com) 53

It's been almost a year since RED, a company known for its high-end $10,000+ cameras, teased a smartphone called the RED Hydrogen One. Several months have passed since the phone was announced and we still don't know much about it, aside from it having a very industrial design and "Hydrogen holographic display." Earlier this week, AT&T and Verizon confirmed that they'll launch the device later this year. Now, The Verge's Dieter Bohn has shared his hands-on impressions with the device, which he claims to be "one of the most ambitious smartphones in years from a company not named Apple, Google, or Samsung." Here's an excerpt from the report: The company better known for high-end 4K cameras with names like "Weapon" and "Epic-w" isn't entering the smartphone game simply to sell you a better Android phone. No, this phone is meant to be one piece of a modular system of cameras and other media creation equipment -- the company claims it will be "the foundation of a future multi-dimensional media system." To that end, it has a big set of pogo-pins on the back to connect it to RED's other cameras also to allow users to attach (forthcoming) modules to it, including lens mounts. If it were just a modular smartphone, we'd be talking about whether we really expected the company to produce enough modules to support it.

RED is planning on starting with a module that is essentially a huge camera sensor -- the company is not ready to give exact details, but the plan is definitely more towards DSLR size than smartphone size. Then, according to CEO Jim Jannard, the company wants any traditional big camera lens to be attached to it. Answering a fan question, he joked that support for lenses will be "pretty limited," working "just" with Fuji, Canon, Nikon, Leica, and more. [...] The processor inside will be a slightly-out-of-date Qualcomm Snapdragon 835, but it seemed fast enough in the few demos I was able to try. Honestly, though, if you're looking to get this thing just as a phone, you're probably making your decision based on the wrong metrics. It's probably going to be a perfectly capable phone, but at this price (starting at $1,195) what you're buying into is the module ecosystem.

No Fossil Fuel-Based Generation Was Added To US Grid Last Month (arstechnica.com) 123

An anonymous reader quotes a report from Ars Technica: In the U.S., two types of electricity generation are on the rise: natural gas and renewables. If one of those is set to make a bigger mark than the other this year, it's natural gas: in 2018, natural gas-burning capacity is expected to outpace renewable capacity for the first time in five years, according to data from the Energy Information Agency. Although natural gas additions are expected to overtake renewable energy additions in 2018, forecasts for renewable energy additions to the grid roughly match what we saw in 2017. Natural gas is overtaking renewables not because renewable energy adoption is slowing, but more because natural gas facilities are seeing a considerable boom.

In fact, barring any changes in the EIA numbers, natural gas, wind, and solar generation are the only electricity generation sources that will be added to the U.S. grid in any consequential manner in 2018. Battery, hydroelectric, and biomass facilities make up the small percentage of "other" sources that are expected to come online this year. Renewable energy also started off the year strong. According to the EIA, "in February 2018, for the first time in decades, all of the new generating capacity coming online within a month were non-fossil-fueled. Of the 475 MW of capacity that came online in February, 81 percent was wind, 16 percent was solar photovoltaic, and the remaining 3 percent was hydro and biomass."

Ask Slashdot: Could Asimov's Three Laws of Robotics Ensure Safe AI? (wikipedia.org) 234

"If science-fiction has already explored the issue of humans and intelligent robots or AI co-existing in various ways, isn't there a lot to be learned...?" asks Slashdot reader OpenSourceAllTheWay. There is much screaming lately about possible dangers to humanity posed by AI that gets smarter and smarter and more capable and might -- at some point -- even decide that humans are a problem for the planet. But some seminal science-fiction works mulled such scenarios long before even 8-bit home computers entered our lives.
The original submission cites Isaac Asimov's Three Laws of Robotics from the 1950 collection I, Robot.
  • A robot may not injure a human being or, through inaction, allow a human being to come to harm.
  • A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
  • A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.

The original submission asks, "If you programmed an AI not to be able to break an updated and extended version of Asimov's Laws, would you not have reasonable confidence that the AI won't go crazy and start harming humans? Or are Asimov and other writers who mulled these questions 'So 20th Century' that AI builders won't even consider learning from their work?"

Wolfrider (Slashdot reader #856) is an Asimov fan, and writes that "Eventually I came across an article with the critical observation that the '3 Laws' were used by Asimov to drive plot points and were not to be seriously considered as 'basics' for robot behavior. Additionally, Giskard comes up with a '4th Law' on his own and (as he is dying) passes it on to R. Daneel Olivaw."

And Slashdot reader Rick Schumann argues that Asimov's Three Laws of Robotics "would only ever apply to a synthetic mind that can actually think; nothing currently being produced is capable of any such thing, therefore it does not apply..."

But what are your own thoughts? Do you think Asimov's Three Laws of Robotics could ensure safe AI?

Rebuilding the PDP-11/70 with a Raspberry Pi (wixsite.com) 93

"You could look at this as a smallish PDP-11/70, built with modern parts," Oscar Vermeulen writes on his site. "Or alternatively, and equally valid, as a fancy front panel case for a Raspberry Pi."

Long-time Slashdot reader cptnapalm writes: Oscar Vermeulen's PiDP-11 front panel, modeling a PDP-11/70 in all its colorful glory, has been released to beta testers. This is Mr. Vermeulen's second DEC front panel; his PiDP-8 was released a few years ago. The PiDP-11 panel is designed to work with a Raspberry Pi running simh or, possibly, a FPGA implementation of the Digital Equipment Corporation PDP-11... In addition to the front panel with its switches and blinkenlights, also included is a prototyping area for the possibility of adding new hardware...

UNIX and later BSD were developed on the PDP-11, including both the creation of the C language, the pipe concept and the text editor vi.
