Why DRAM Chipmakers Need Their Own OPEC (bloomberg.com) 132

DRAM is just as much a commodity as oil. But manufacturers can only dream about the benefits of negotiating supply together. From a report: You've got to feel for the world's biggest suppliers of DRAM. Makers of these chips, which temporarily store information in PCs, smartphones and services, endured years of boom-bust profit swings and bruising competition long before the trade war began. The sector finally consolidated into just three companies holding 95% of global supply of DRAM. And yet earnings stability still eludes them. SK Hynix early Thursday posted an 88% drop in second-quarter net income, the lowest in three years and missing estimates. Investors cheered when the South Korean company concurrently announced that it will slow expansion.

SK Hynix supplies around 30% of DRAM. As much as manufacturers would like to tell you otherwise, these chips are all pretty similar, which is why they're considered a commodity. And with most commodities, like oil, prices shift with supply and demand. Profits, in turn, depend on balancing price and supply against the cost of the multi-billion dollar factories required to churn out these chips. It's no easy task. In fact, profitability is as much a function of game theory as capacity and cost management. If you cut supply while your competitor maintains output, prices may rise -- but most of that benefit goes to your rival and you miss out. If no one cuts supply even when demand is falling, then you're all likely to suffer lower prices, which could drag you into the red.

There's a collection of 14 nations well aware of how this works that came up with an ingenious solution: Sit down and negotiate supply together. Except they're peddling oil, not chips, and the Organization of the Petroleum Exporting Countries can't always see eye to eye.

Medical research should be entirely funded by the public, and all patents and treatments that result made available to the public for free.

So, you'd ban any privately funded medical research then? That doesn't sound like a society I'd want to live in. In that case the government has a monopoly on medical research and if you had some disease that the government didn't feel like researching then you won't get treated. If you had piles of money that you'd be willing to spend on a cure for your own disease, or donate to someone with a similar goal of finding a cure, then the government would bar you from doing so.

No need to ban it. Just need to stop enforcing the monopolies.
If government paid for it, everyone can have it.
If you paid for it, you can either share it, or not, but the government doesn't prevent others from using it, it's your problem.

What Image Should Represent All of Humanity On Wikipedia? (wired.com) 349

An anonymous reader writes: If aliens ever do come across the Pioneer spacecraft and make assumptions about the entire human species based on the man and woman etched onto the plaque it carries, this is what they will think of us: We all look like white people; we all look about 30ish years old; we do not wear clothes. It's a problem you encounter anytime you have to choose a few individuals to represent an entire group, and it's one that the editors of Wikipedia have debated for years: What image should grace the top of the "human" entry in the online dictionary?

The photo that's there now, after years of feverish debate, is of an Akha couple from a region of Thailand along the Mekong river. "The photo of the Akha couple remain humanity's type specimens on Wikipedia," writes author Ellen Airhart. "Just as a shriveled northeastern leopard frog at the University of Michigan Museum of Zoology represents its whole species, so this couple stands for all of us."

Such musing about the taxonomic representation of the human species could actually have a big impact on our digital future. "Future scientists will have to teach computers, not aliens, to recognize the human image. Right now, software engineers program artificial intelligence to recognize people by feeding them millions of pictures of faces," she writes. "But whose faces? Computer scientists run into the same questions about gender, race, and culture that the Wikipedia editors encountered. Being able to use more than one photo expands the conversation but does not necessarily make it easier."

Tesla Is Prohibiting Commercial Drivers From Using Its Supercharger Stations (theverge.com) 282

Tesla has issued a new policy called Supercharger Fair Use, which prohibits new commercial drivers from using the red-and-white charging ports. The reason behind this new policy is to help alleviate congestion and improve the experience for others who rely on the Supercharging services. The Verge reports: Tesla says that the stations are intended for drivers who don't have ready options for charging at home or at work, and that when they're not used for this purpose, "it negatively impacts the availability of Supercharging services for others." Thus, the new policy says that for vehicles purchased after December 15th, drivers who plan to use their vehicles as a taxi, for ridesharing, commercial delivery or transportation, governmental purposes, or other commercial ventures won't be permitted to use the free stations. The company tracks usage and driver behavior, and if they find that someone isn't complying with the policy, they might be asked to stop, and simply limit or block one's vehicle from the stations in certain instances. The policy went into effect on Friday, December 15th, 2017. A Tesla spokesperson said that the company does "encourage the use of Teslas for commercial purposes," and that they will work with drivers to find other places to charge their vehicles. The policy carve out an exception, saying that some stations might be excluded, depending on local circumstances.

Elon Musk Inspired an Industry of Hyperloop Startups. Now He's Building His Own (bloomberg.com) 153

An anonymous reader shares a report: Elon Musk introduced his vision for a futuristic mode of tube-based transportation called the hyperloop in 2013. In an exhaustive white paper, he laid out a body of research conducted with his team at Space Exploration Technologies demonstrating the system's viability and seemingly offered it as a gift to the entrepreneurial community. "I don't have any plan to execute because I must remain focused on SpaceX and Tesla," he said in a conference call at the time. He apparently changed his mind. Last month, the SpaceX and Tesla chief executive officer revealed on Twitter that he'd received "verbal government approval" to build a hyperloop capable of ferrying passengers between New York and Washington, D.C., in 29 minutes. The tweet came as a shock to executives at the various startups racing to develop their own hyperloops based on Musk's specifications. Several of them initially expressed hope that Musk would simply dig the tunnels and perhaps choose one of their startups to create the physical infrastructure, which involves a tube-encased train traveling at speeds faster than an airplane. Nope. A person close to Musk said his plan is to build the entire thing, including the hyperloop system. Musk also holds a trademark for "Hyperloop" through SpaceX, which could be used to prevent other companies from using the term, according to U.S. public records. The billionaire's unexpected entry into the hyperloop business could threaten the ambitions of three startups, which have raised about $200 million combined from venture backers. "There's probably a finite amount of capital willing to bet on this space -- and bet against him," said Jonathan Silver, the former loan programs director at the U.S. Department of Energy. Silver learned not to underestimate Musk after overseeing a 2010 loan of $465 million to Tesla, which the electric carmaker paid back, with interest, nine years ahead of schedule.

Uber Drivers Gang Up To Cause Surge Pricing, Research Says (telegraph.co.uk) 164

Researchers at the University of Warwick found Uber drivers team up in gangs to force higher prices before they pick up passengers. How do they perform such a feat? They trick the app into thinking their is a shortage of cars in order to raise surge prices. The Telegraph reports: According to the study. drivers manipulate Uber's algorithm by logging out of the app at the same time, making it think that there is a shortage of cars. Uber raises its fare prices when there is a high demand for vehicles and a short supply of drivers available. Fares are known to increase during peak times such as rush hour, during public events and late at night. Surge pricing can boost the cost of rides to multiple times the normal rate. The study said drivers have been coordinating forced surge pricing, after interviews with drivers in London and New York, and research on online forums such as Uberpeople.net. In a post on the website for drivers, seen by the researchers, one person said: "Guys, stay logged off until surge. Less supply high demand = surge." The researchers said the collusion reflects driver dissatisfaction with Uber's policies regarding them, and exposes the "ethically questionable" nature of its algorithm. It is not clear how much impact the trick has had on prices. Uber denied that the practice is widespread.

Dadbot: How a Son Made a Chatbot of His Dying Dad (www.cbc.ca) 114

theodp writes: In A Son's Race to Give His Dying Father Artificial Immortality (Warning: may be paywalled; alternate source), James Vlahos recounts his efforts to turn the story of his father's life -- as told by his 80-year-old Dad in his final months after being diagnosed with stage IV lung cancer -- into what Vlahos calls "a Dadbot -- a chatbot that emulates not a children's toy but the very real man who is my father." Given the limits of tech at the time (2016) and his own inexperience as a programmer, Vlahos recognized that the bot would never be more than a shadow of his real dad, but hoped to get the bot to communicate in his father's distinctive manner and convey at least some sense of his personality. Of the first time he demoed the bot for his parents, Vlahos writes: "Emboldened, I bring up something that has preoccupied me for months. 'This is a leading question, but answer it honestly,' I say, fumbling for words. 'Does it give you any comfort, or perhaps none -- the idea that whenever it is that you shed this mortal coil, that there is something that can help tell your stories and knows your history?' My dad looks off. When he answers, he sounds wearier than he did moments before. 'I know all of this shit,' he says, dismissing the compendium of facts stored in the Dadbot with a little wave. But he does take comfort in knowing that the Dadbot will share them with others. 'My family, particularly. And the grandkids, who won't know any of this stuff.' He's got seven of them, including my sons, Jonah and Zeke, all of whom call him Papou, the Greek term for grandfather. 'So this is great,' my dad says. 'I very much appreciate it.'"

"when there's really a need (ie big deadline ..."

That's what I mean by "braindead". A big deadline should not translate to OT, and OT is never a good fix for bad planning.
The fact that you don't realize that is what makes you braindead.

A better thing to value is people that get the work done, regardless the means. If I have a lazy sysadmin, that writes scripts in the morning so they can play videogames all afternoon, I'll value that, because that is what drives value . Effort is worth nothing. Results are.

What you say has some truth, but has nothing to do with the post you replied to.
I was saying that for a certain kind of management, appearances are more important than success, so you need to look the part they expect in order to get ahead.

Of course, there are several different ways of creating value for a company. Looks like you take pride in being a firefighter. I personally don't like that line of work, and prefer to not have a need for those.
Same thing for planning. If your company meets deadlines by working OT, then all managers involved are incompetent and unreliable.

May be both, but not in the obvious way.

Long hours mean lower productivity, but it also means you are there, in the office, pushing hard.

That is misread as "work ethic", and hard work, and productivity.

Braindead managers will think they are getting more bang for their buck by getting more than 40 hours a week, so you will be seen as more valuable than someone doing their 40 hours, no matter the results.

The thing is that braindead managers do exist, and it may be the case that you need to appeal to them to get ahead.

It happens more in large companies, old fashioned ones, or any organization not strictly focused on success, or at least where productivity is hard to measure.

Researchers Create a T-Shirt That Monitors the Wearer's Breathing Rate In Real Time (sciencedaily.com) 38

"Researchers at Universite Laval's Faculty of Science and Engineering and its Center for Optics, Photonics, and Lasers have created a smart T-shirt that monitors the wearer's respiratory rate in real time," reports Science Daily. The details have been published in the latest edition of Sensors. From the report: Unlike other methods of measuring respiratory rate, the smart T shirt works without any wires, electrodes, or sensors attached to the user's body, explains Younes Messaddeq, the professor who led the team that developed the technology. "The T shirt is really comfortable and doesn't inhibit the subject's natural movements. Our tests show that the data captured by the shirt is reliable, whether the user is lying down, sitting, standing, or moving around." The key to the smart T shirt is an antenna sewn in at chest level that's made of a hollow optical fiber coated with a thin layer of silver on its inner surface. The fiber's exterior surface is covered in a polymer that protects it against the environment. "The antenna does double duty, sensing and transmitting the signals created by respiratory movements," adds Professor Messaddeq, who also holds the Canada Excellence Research Chair in Photonic Innovations. "The data can be sent to the user's smartphone or a nearby computer." As the wearer breathes in, the smart fiber senses the increase in both thorax circumference and the volume of air in the lungs, explains Messaddeq. "These changes modify some of the resonant frequency of the antenna. That's why the T shirt doesn't need to be tight or in direct contact with the wearer's skin. The oscillations that occur with each breath are enough for the fiber to sense the user's respiratory rate."
