Technology writer Tom Chanter explores the life story of venture capitalist Marc Andreessen to ask whether software will not only eat the world, but also the jobs of what one historian predicts will be a "massive new unworking class: people devoid of any economic, political or even artistic value." Can Marc Andreessen prevent a so-called "useless class" who "will not merely be unemployed -- it will be unemployable"?

Andreessen grew up in New Lisbon, Wisconsin (population: 1,500), and taught himself the BASIC programming language at age 8. He co-developed the original Mosaic web browser before he'd graduated from college, went on to co-found Netscape, and by age 23 was worth $53 million. He then transformed into a "super angel" investor in companies like Twitter, Airbnb, Lyft, Facebook, Skype, and GitHub. "Having been an innovator in the tech start-up game, Andreessen is now an innovator in the tech venture capital game," writes Chanter. "He is a jedi that has become the master." In 2011, Marc Andreessen published an article in the Wall Street Journal titled, Why Software Is Eating The World. He wrote, "Over the next 10 years, the battles between incumbents and software-powered insurgents will be epic...." 7 years later, it's clear Andreessen was correct. Lyft has destroyed taxi jobs. Airbnb has destroyed hotel jobs. Amazon destroyed independent bookstores. How does Andreessen feel about that? "Screw the independent bookstores," he said in his New Yorker profile. "There weren't any near where I grew up. There were only ones in college towns. The rest of us could go pound sand."
But the 4,900-word article also notes Andreessen's pledge to give half his income to charitable causes -- and his observation in a 2015 interview that outside of the United States, global income inequality is falling, not rising. "He has seen technology transform his own life, and has seen how technology has bridged the global wealth gap. Why shouldn't he be optimistic about the future of America's working class?"

And Andreessen's ultimate answer to the jobs destroyed by technology may be Udacity. The article cites Andreessen's investment in the company in 2012, and points to the online education platform's hopeful mission statement. "Virtually anyone on the planet with an internet connection and a commitment to self-empowerment through learning can come to Udacity, master a suite of job-ready skills, and pursue rewarding employment."

As a boy in Wisconsin he was starved for information. He has created an education institution accessible from Wisconsin to Africa. As a boy in Wisconsin he was starved for connection. He has married an innovative philanthropist and author, Laura Arrillaga-Andreessen. They have a son named John. Andreessen is optimistic for both the working class and the future tech elite.

In his New Yorker profile he says of his son, "He'll come of age in a world where ten or a hundred times more people will be able to contribute in science and medicine and the arts, a more peaceful and prosperous world."

He added, tongue in cheek, "I'm going to teach him how to take over that world!"

An anonymous reader quotes a report from Electrek: Florida Power & Light has joined the race to build the world's largest solar battery storage system, announcing plans for its massive Manatee Energy Storage Center. The utility plans to build a 409 MW/900 MWh battery, to be powered by an existing FPL solar plant in Manatee County, Florida. It will begin serving customers in 2021. FPL says the battery system will be able to power 329,000 homes for two hours. For comparison, FPL notes the battery system is equivalent to 100 million iPhone batteries, or 300 million AA batteries. The system will be used in periods of high demand. The utility company also said that it will accelerate the retirement of two natural gas facilities at a nearby power plant. "FPL says the project will save customers more than $100 million while eliminating more than 1 million tons of carbon emissions, though no cost estimates for the project were disclosed," reports Electrek.

And while the Manatee Energy Storage Center is projected to be the "world's largest solar-powered battery storage system," it will have some competition from Texas where there are plans to build a 495 MW battery storage system that would be paired with an equivalent 495 MW solar farm in Borden County, Texas. It too is due to come online in 2021.

After partnering with HTC to launch the Vive in 2016, Valve has moved ahead with plans to launch its own headset, called the Valve Index, in May 2019. Ars Technica reports: The news came on Friday in the form of a single teaser image, shown above, of a headset with the phrase "Valve Index" written on its front. The front of the headset is flanked by at least two sensors. This shadow-covered hardware matches the leaked headset reported by UploadVR in November of last year. That report hinted to Valve's headset supporting a wider, 135-degree field-of-view (FOV), as opposed to the roughly 110-degree FOV of the original HTC Vive and Oculus Rift.

Valve's dedicated website for the new device includes no other information than the above image and the date "May 2019." It does not include any mention of the new SteamVR Knuckles controllers, which Valve has advertised pretty heavily via developer outreach since their 2016 reveal and a later series of improved prototypes in 2018. This page also doesn't mention a series of three Valve-produced VR games that have been repeatedly advertised by Valve co-founder Gabe Newell since 2017. There's very little information about the headset, but after cranking up the brightness and contrast of the teaser image, Ars Technica's Sam Machkovech was able to find "a series of six dots on one of the headset's surfaces, [...] which may hint to this headset's use of an outside tracking sensor, a la the HTC Vive's infrared trackers." He adds: "Even so, those two giant lenses imply that 'inside-out' tracking, managed entirely by the headset without any extra webcams or sensors, may also be in the cards. Additionally, we can see a giant physical slider, which is likely linked to interpupillary distance (IPD), a precise measurement needed to ensure maximum VR comfort."

After tearing apart Apple's new second-generation AirPods, the repair guide site found that there is no practical way to service or repair them even at a professional shop. They labeled them as "disappointingly disposable." Ars Technica reports: iFixit had to go to almost comical lengths to open the AirPods up, and despite their expertise and tools, the iFixit team was unable to do so without permanently damaging the product. [...] That's disappointing, given that the batteries in the AirPods won't last longer than a few years with heavy use, and they're hard to recycle. Apple does offer to recycle headphones through partners as part of its Apple GiveBack program, but the GiveBack Web portal does not offer a product-specific category for AirPods to consumers like it does with most other Apple products. Consumers may simply select a general "headphones & speakers" category on the site.

The teardown also revealed some differences from the first-generation AirPods. The battery is the same size, but iFixit identified the new, Bluetooth 5-ready H1 chip in the earbuds themselves. The site also found some small differences likely related to Apple's efforts to increase the case's water resistance. For all the details, visit iFixit's teardown page for the product. All told, iFixit gave the AirPods a 0 out of 10 for repairability -- that's low even for Apple products. By contrast, the site also opened up Samsung's Galaxy Buds and gave them a 6 out of 10.

One and a half years after announcing a wireless charging mat for iPhones, Apple Watches, and AirPods called AirPower, Apple has unexpectedly cancelled the accessory. From a report: It notably missed its expected shipping dates multiple times, including a potential release alongside the second-generation version of AirPods and charging case this week. "After much effort, we've concluded AirPower will not achieve our high standards and we have cancelled the project," said Apple SVP of Hardware Engineering Dan Riccio in a statement today. "We apologize to those customers who were looking forward to this launch. We continue to believe that the future is wireless and are committed to push the wireless experience forward." Mark Gurman of Bloomberg, adds, "This is fairly unprecedented and unbelievable. The AirPods even have a picture of the AirPower on the box."

New submitter pecosdave writes: I need suggestions for commercially-made ARM systems that will work in temperature ranges from -35F to 140F (-37C to 60C) for an engineering project. These things are going to be in metal boxes on the side of Texas Highways. The existing Intel systems we're using in other areas are all fan-less, but I'm not going to rule out systems with fans. Considering the extremes of Texas temperatures I'm actually contemplating putting fans on top of our fan-less systems anyways. Almost everything I can find pre-made with ARM is a bare board, or something not nearly as temperature tolerant as some Intel systems I can find. The very nature of an ARM processor should be more tolerant simply because they produce less heat, but I can't seem to find any manufacturers exploiting that fact. Slashdot reader pecosdave added more details in a comment: "It's more closely related to speed cameras, but it's not a speed camera. It's for a toll road, and its main job is to take pictures of a sign at about 10 FPS, though less is probably fine, with a time-stamp so if someone runs the toll we have a separate picture of the current price. If there's a problem with the sign it shows up as well. They just want something local to store it I guess in case the fiber link goes down. We're going to run it rather low-res too to keep the CPU and storage overhead low. I figure 640x480@10FPS is reasonable, but that's not set in stone."

prpplague writes: Despite Linus Torvald's recent claims ARM won't win in the server space, there are very specific use cases where ARM is making advances into the datacenter. One of those is for use with software-defined storage with open-source projects like CEPH. In a recent The Register article, Softiron's CTO Phil Straw states about their ARM-based CEPH appliances: "It's a totally shitty computer, but what we are trying to do here is storage, and not compute, so when you look at the IO, when you look at the buffering, when you look at the data paths, there's amazing performance -- we can approach something like a quarter of a petabyte, at 200Gbps wireline throughput." Straw claimed that, on average, SoftIron servers run 25C cooler than a comparable system powered by Xeons." So... ARM in the datacenter might be saying, "I'm not quite dead yet!"

Xiaomi is teasing a new 100W quick-charging solution for mobile phones that can fully charge a large 4,000mAh battery in just 17 minutes. Ars Technica reports: The video shows a charging race between two phones, Xiaomi's unnamed "100W" prototype and a phone with "50W" charging from "Brand O," which looks like it's an Oppo RX17 Pro. I put both of these wattage ratings in quotations because neither phone actually hits its rated charging speed. Xiaomi's video shows a live, in-line power reading, and the "100W" charging shows a sustained ~80W (18V / 4.5A) from about 5-30 percent, with a peak of 88W. The competing 50W Oppo quick-charge solution caps out at around 40W.

Branding aside, what matters is the actual charging speed, and Xiaomi's ability to fully charge a phone battery in 17 minutes is impressive. The test stops when the Xiaomi phone fills up, leaving the Oppo battery stuck at a mere 65 percent. Considering that Xiaomi was charging a 4000mAh battery and that Oppo only had a 3700mAh battery, Xiaomi's solution is about 1.6 times faster than Oppo's quick charge, which is currently the fastest charging scheme on the market. Unfortunately, Xiaomi didn't offer any specifics on how its charging solution works.

GITAI is a robotics startup with offices in Japan and the United States that's developing tech to put humanoid telepresence robots in space to take over for astronauts. IEEE: This week, GITAI is announcing a joint research agreement with JAXA (the Japanese Aerospace Exploration Agency) to see what it takes for robots to be useful in orbit, with the goal of substantially reducing the amount of money spent sending food and air up to those demanding humans on the International Space Station. It's also worth noting that GITAI has some new hires, including folks from the famous (and somewhat mysterious) Japanese bipedal robot company SCHAFT.

[...] GITAI says that their robots will "reduce the cost of space work to 10 percent" of the cost of using a real astronaut, by instead relying on earthbound humans for immersive teleoperation. As you might expect, the trouble with immersive teleoperation between Earth and orbit is getting data back and forth over a restrictive network. Part of GITAI's secret sauce involves compressing "data of 360-degree camera with resolution of 2.7K from original data volume of 800 Mbps to average 2.5 Mbps." At the same time, they've managed to reduce latency to 60 ms, which is really quite good, for talking to space. The plan is to get all of this working in low Earth orbit by 2020.

Massachusetts Senator and Democratic Presidential hopeful Elizabeth Warren has become the highest profile politician to support right to repair legislation in the United States. From a report: On Wednesday, Warren outlined a sweeping plan to support family farms and diminish the power of corporate agriculture. At the top of the list, she supports a national right-to-repair law for tractors and other agricultural equipment. That means she supports the simple idea that people who own a tractor should be able to repair it without permission from John Deere or any other manufacturer. "Farmers should be able to repair their own equipment or choose between multiple repair shops," Warren said in a Medium post outlining her proposal. "That's why I strongly support a national right-to-repair law that empowers farmers to repair their equipment without going to an authorized agent." For now, Warren's proposal would apply only to farm equipment, not consumer electronics.

[...] Farmers operating John Deere tractors have been fighting against John Deere's repair monopoly for years. Device manufacturers don't want people repairing their own stuff and they've taken pains to make it difficult to do so. Newer John Deere equipment comes loaded with software and firmware that make it impossible for farmers to fix their own equipment. Instead, they have to call an authorized dealer and wait for them to show up -- a fix that's too slow and too costly for a farmer. "The national right-to-repair law should require manufacturers of farm equipment to make diagnostic tools, manuals, and other repair-related resources available to any individual or business, not just their own dealerships and authorized agents," Warren said. "This will not only allow individuals to fix their own equipment -- reducing delays -- but it will also create competition among dealers and independent repair shops, bringing down prices overall."

Joanna Stern, writing for the Wall Street Journal [the link may be paywalled]: Why is the breaking of my MacBook Air keyboard so insanely maddening? Let's take a trip down Memory Lane.
April 2015: Apple releases the all-new MacBook with a "butterfly" keyboard. In order to achieve extreme thinness, the keys are much flatter than older generations but the butterfly mechanism underneath, for which the keyboard is named, aims to replicate the bounce of a more traditional keyboard.
October 2016: The MacBook Pro arrives with a second-generation butterfly keyboard. A few months later, some begin to report that letters or characters don't appear, that keys get stuck or that letters unexpectedly repeat.
June 2018: Apple launches a keyboard repair program for what the company says is a "small percentage" of MacBook and MacBook Pro keyboards impacted.
July 2018: Apple releases a new high-end MacBook Pro with the third-generation of the keyboard that's said to fix the issues.
October 2018: Apple's new MacBook Air also has the third-generation keyboard. I recommend it, and even get one for myself.

Which brings us to the grand year 2019 and my MacBook Air's faulty E and R keys. Others have had problems with Apple's latest laptops, too. A proposed nationwide class-action suit alleges that Apple has been aware of the defective nature of these keyboards since 2015 yet sold affected laptops without disclosing the problem. "We are aware that a small number of users are having issues with their third-generation butterfly keyboard and for that we are sorry," an Apple spokesman said in a statement. "The vast majority of Mac notebook customers are having a positive experience with the new keyboard." If you have a problem, contact Apple customer service, he added. John Gruber, a long time Apple columnist: I consider these keyboards the worst products in Apple history. MacBooks should have the best keyboards in the industry; instead they're the worst. They're doing lasting harm to the reputation of the MacBook brand.

Engineers at the University of Michigan have built the first millimeter-scale stand-alone device that meets Bluetooth Low Energy (BLE) specifications. "Consuming just 0.6 milliwatts during transmission, it would broadcast for 11 years using a typical 5.8-mm coin battery," reports IEEE Spectrum. "Such a millimeter-scale BLE radio would allow these ant-sized sensors to communicate with ordinary equipment, even a smartphone." From the report: The transmitter chip, which debuted last month at IEEE International Solid-State Circuits Conference, had to solve two problems. The first is power consumption, and the second is the size of the antenna. An ordinary transmitter circuit requires a tunable RF oscillator to generate the frequency, a power amplifier to boost its amplitude, and an antenna to radiate the signal. The Michigan team combined the oscillator and the antenna in a way that made the amplifier unnecessary. They called their invention a power oscillator. The key part of an oscillator is the resonant tank circuit: an inductor and a capacitor. Energy sloshes back and forth between the inductor's magnetic field and the capacitor's electric field at a resonant frequency determined by the capacitance and inductance. In the new circuit, the team used the antenna itself as the inductor in the resonant tank. Because it was acting as an inductor, the antenna radiated using changing magnetic field instead of an electric field; that meant it could be more compact.

However, size wasn't the only thing. Quality factor, or Q, is a dimensionless quantity that basically says how efficient your resonator is. As a 14-mm long loop of conductor, the antenna was considerably larger than an on-chip inductor for a millimeter-scale radio could be. That led to a Q was that was about five times what an on-chip inductor would deliver. Though it was a much more efficient solution, in order to meet BLE specifications, the team needed a better way to power the power oscillator. Their solution was to build an on-chip transformer into the circuit that supplies power to it. The transformer looks like two nested coils. One coil is attached to the supply voltage end of the oscillator circuit, and the other is attached to ground side. Pumping the transformer at a frequency twice that of the power amplifier wound up efficiently boosting the flow of power to the antenna.

Two variants of the Pixel Slate, a tablet-laptop hybrid that Google unveiled last year, have been "out of stock" for months now, leading many to believe that Google may have quietly gotten rid of them. From a report: [The Pixel Slate that are powered by the Celeron processor] are nowhere to be seen. They've been out of stock on the Google Store -- the only place these models were very briefly available -- since shortly after launch, four months ago. The $599 and $699 versions of the Pixel Slate brought sub-iPad Pro pricing to Google's prosumer tablet, even if it turned out that the tablet itself beat the iPad in pretty much no sense that mattered. Marques Brownlee, typically known for his easy-going takes and willingness to embrace misunderstood tech products, basically called the cheaper Celeron Slate a turd. This was not a good look for Google. Shortly after that, the Celeron Pixel Slate showed up as sold out on the Google Store, and that status hasn't changed since.

A reader shares a report from Engadget: ASUS may have inadvertently pushed malware to some of its computers through its update tool, but it at least it has a fix ready to go. The PC maker has released a new version of its Live Update software for laptops that addresses the ShadowHammer backdoor attack. It also promised "multiple security verification mechanisms" to reduce the chances of further attacks, and started using an "enhanced end-to-end encryption mechanism." There are upgrades to the behind-the-scenes server system to prevent future attacks, ASUS added.

The company simultaneously reiterated the narrow scope of ShadowHammer, noting that the malware targeted a "very small and specific user group." It's believed to be an Advanced Persistent Threat -- that is, a state-backed assault against organizations rather than everyday users. Other ASUS devices weren't affected, according to a notice. While the fix is reassuring, it also raises questions as to why the systems weren't locked down earlier. Update tools are prime targets for hackers precisely because they're both trusted and have deep access to the operating system -- tight security is necessary to prevent an intruder from hijacking the process.

An anonymous reader quotes a report from The Guardian: About 1.5 million workers in Britain are at high risk of losing their jobs to automation, according to government estimates, with women and those in part-time work most affected. Supermarket checkout assistants have already borne the brunt of the phenomenon, the Office for National Statistics found, with 25.3% of jobs disappearing between 2011 and 2017. Other jobs where automation has taken its toll include laundry workers, farm workers and tyre fitters, among which numbers have dropped by 15% or more, said the ONS, as machines have replaced labor.

Women are most likely to lose out, said the ONS. "The analysis showed a higher proportion of roles currently filled by women are at risk of automation; in 2017, 70.2% of high-risk jobs were held by women." It named Tamworth, Rutland and South Holland in Lincolnshire as the areas most exposed to automation -- partly reflecting a relatively high level of farm workers -- while Camden in north London has the workers least at risk. But the ONS analysis also found many workers -- especially those in their mid to late 30s and who work in London and the south-east -- have little to fear from the rise of the robots. Those with higher levels of education appear to be better protected. "The ONS said that, of the jobs at risk, 39% were held by people whose educational attainment level was GCSE or below, while 1.2% were held by those who had been through higher education or university," the report says.

Employment has fallen in jobs that can be easily automated and risen in those which are trickier for robots, damping hopes that higher minimum wages could unleash a wave of investment in automation. From a report: Statistics from the Office for National Statistics published on Monday showed that in 2011 about 8.1 per cent of workers were in jobs with a "high" risk of automation, but by 2017 that had fallen to 7.4 per cent. [Editor's note: the link may be paywalled; alternative source and original study.] The ONS report highlighted that fewer workers remain in areas that can be easily automated, such as dry cleaning and laundry jobs, which fell by 28 per cent between 2011 and 2017, and retail cashier work, which fell by 25.3 per cent over the same period.

Since the financial crisis the UK has enjoyed rapid growth in employment combined with one of the lowest rates of investment spending of any large rich country. Many economists have suggested that hiring cheap labour instead of investment in new techniques is behind the country's weak rate of productivity growth. Policymakers had hoped that increasing the minimum wage would spur companies to replace low-paid jobs with machines, in turn boosting growth in productivity. [...] But the ONS analysis suggests the increase in employment over the past decade has not come from jobs that could easily be done by machines. Instead, since 2011 the UK lost jobs with a high or medium risk of automation, like shelf fillers, but gained them in areas with a low risk, such as physiotherapy.

"In a remote stretch of New Mexico desert, the U.S. government put in motion an experiment aimed at proving to the world that radioactive waste could be safely disposed of deep underground..." reports the Associated Press: Twenty years and more than 12,380 shipments later, tons of Cold War-era waste from decades of bomb-making and nuclear research across the U.S. have been stashed in the salt caverns that make up the underground facility. Each week, several shipments of special boxes and barrels packed with lab coats, rubber gloves, tools and debris contaminated with plutonium and other radioactive elements are trucked to the site.

But the Waste Isolation Pilot Plant has not been without issues. A 2014 radiation leak forced an expensive, nearly three-year closure, delayed the federal government's cleanup program and prompted policy changes at national laboratories and defense-related sites across the U.S. More recently, the U.S. Department of Energy said it would investigate reports that workers may have been exposed last year to hazardous chemicals. Still, supporters consider the repository a success, saying it provides a viable option for dealing with a multibillion-dollar mess that stretches from a decommissioned nuclear weapons production site in Washington state to one of the nation's top nuclear research labs, in Idaho, and locations as far east as South Carolina. If it weren't for the Waste Isolation Pilot Plant, many containers of plutonium-contaminated waste would be outside, exposed to the weather and susceptible to natural disasters, said J.R. Stroble, head of business operations at the Department of Energy's Carlsbad Field Office, which oversees the contractor that operates the repository.

"The whole purpose of WIPP is to isolate this long-lived radioactive, hazardous waste from the accessible environment, from people and the things people need in order to live life on Earth," he told The Associated Press.

Some of the same podcasters who first extolled AirPods are now complaining about them, reports the Atlantic: The battery can no longer hold a charge, they say, rendering them functionally useless. Apple bloggers agree: "AirPods are starting to show their age for early adopters," Zac Hall, an editor at 9to5Mac, wrote in a post in January, detailing how he frequently hears a low-battery warning in his AirPods now. Earlier this month, Apple Insider tested a pair of AirPods purchased in 2016 against a pair from 2018, and found that the older pair died after two hours and 16 minutes. "That's less than half the stated battery life for a new pair," the writer William Gallagher concluded. Desmond Hughes, who is 35 and lives in Newport News, Virginia, has noticed a similar thing about his own set: At first, their charge lasted five hours, but now they sometimes last only half an hour. He frequently listens to one while charging the other -- not optimal conditions for expensive headphones. He's now gearing up to plunk down more money on another pair....

The lithium-ion batteries that power AirPods are everywhere. One industry report forecast that sales would grow to $109.72 billion by 2026, from $36.2 billion in 2018. They charge faster, last longer, and pack more power into a small space than other types of batteries do. But they die faster, too, often after just a few years, because every time you charge them, they degrade a little. They can also catch fire or explode if they become damaged, so technology companies make them difficult, if not impossible, for consumers to replace themselves. The result: A lot of barely chargeable AirPods and wireless mice and Bluetooth speakers are ending up in the trash as consumers go through products -- even expensive ones -- faster than ever....

Of the 3.4 million tons of electronic waste generated in America in 2012 -- an 80 percent increase from 2000 -- just 29 percent was recycled.
The article notes that Wednesday Apple announced a new generation of AirPods -- but "did not say whether the devices would have longer lives."

They also report that Apple "does allow consumers to pay for what it calls a 'battery replacement' for AirPods, but each 'replaced' AirPod is $49."

Esther Schindler (Slashdot reader #16,185) shared this story from Hewlett Packard's Enterprise blog: Storage is a staple of both science and science fiction, and forms the basis, or a crucial component, of many a piece of speculative fiction... [H]ere are eight past visions of the storage future that either passed their error checks or succumbed to bit rot.

Why store vast quantities of data on a device when you can just slap it into someone's head?
The article acknowledges that in many science fiction stories, data is simply preserved using such primitive technologies as "the written word" and "brute-force [human] memory," as well as ordinary real-world storage technologies like the server room in Rogue One: A Star Wars Story, or basic non-cloud-based computers. But there's also wetware -- think "Johnny Mnemonic "-- and the data crystals in Babylon Five.

The article even acknowledges that time Batman beat Mr. Freeze by carving binary code into a wall, giving future generations the recipe for antifreeze.

dmoberhaus writes: In a major breakthrough for DNA computing, researchers from UC Davis, Caltech and Maynooth University developed a technique for creating molecular algorithms that can be reprogrammed. Prior to this research, molecular algorithms had to be painstakingly designed for specific purposes, which is "like having to build a new computer out of new hardware just to run a new piece of software," according to the researchers. This new technique could blow open the door for a host of futuristic DNA computing applications -- nanofactories, light-based computers, etc. -- that would've been impossible before. The paper was published this week in Nature.
