HughPickens.com writes: North Korea announced it has detonated its first hydrogen bomb, dramatically escalating the nuclear challenge from one of the world's most isolated and dangerous states. "This is the self-defensive measure we have to take to defend our right to live in the face of the nuclear threats and blackmail by the United States and to guarantee the security of the Korean Peninsula," said a North Korean announcer on the state-run network. "With this hydrogen bomb test, we have joined the major nuclear powers." The North's announcement came about an hour after detection devices around the world had picked up a 5.1 seismic event that South Korea said was 30 miles from the Punggye-ri site where the North has conducted nuclear tests in the past.

"North Korea's fourth test — in the context of repeated statements by U.S., Chinese, and South Korean leaders — throws down the gauntlet to the international community to go beyond paper resolutions and find a way to impose real costs on North Korea for pursuing this course of action," says Scott Snyder, a Korea expert at the Council on Foreign Relations. According to the NY Times, the test is bound to figure in the American presidential campaign, where several candidates have already cited the North's nuclear experimentation as evidence of American weakness — though they have not prescribed alternative strategies for choking off the program. The United States did not develop its first thermonuclear weapons — commonly known as hydrogen bombs — until 1952, seven years after the first and only use of nuclear weapons in wartime.

iONiUM writes: According to an article at Discover, "Authorities in Brazil have recently issued an unusual and unprecedented announcement to women: don't get pregnant, at least not just yet. Amidst an intractable outbreak of the mosquito-borne Zika virus, public health authorities in Brazil are highly suspicious of an unusual surge of cases of microcephaly among newborn children." There were over 3,000 cases in 2015.

It's believed this virus is linked to shrinking newborns brain, and it is spreading. "Zika virus is transmitted by mosquitoes, and it was first detected in Uganda in the 1940s. After spreading through Africa and parts of Asia, it has made its way to Latin America. There is no known vaccine to prevent or medicine to treat the disease caused by the virus. Since May 2015, the Brazilian government estimates that some 1.5 million people have been infected with the virus." The CDC has published an article about it, and travel warnings are now being issued for pregnant women.

the_newsbeagle writes: Now that it's easy and cheap to build strands of DNA, what kinds of strange new organisms will scientists and start-ups build? That's the question raised as synthetic biology companies like Twist Bioscience and Zymergen start up their DNA manufacturing lines. Researchers who order DNA snippets typically pay on a cost-per-nucleobase basis. These companies say their mass-production techniques could bring prices down to 2 cents per base, which would allow researchers to scale up experiments and learn through trial and error.

HughPickens.com writes: CNN reports that a judge dismissed DUI charges against a woman in upstate New York after being presented with evidence the woman suffers from "auto-brewery syndrome" even though she blew a blood alcohol level more than four times the legal limit. "I had never heard of auto-brewery syndrome before this case," says attorney Joseph Marusak. "But I knew something was amiss when the hospital police took the woman to wanted to release her immediately because she wasn't exhibiting any symptoms." Also known as gut-fermentation syndrome, this rare medical condition can occur when abnormal amounts of gastrointestinal yeast convert common food carbohydrates into ethanol. The process is believed to take place in the small bowel, and is vastly different from the normal gut fermentation in the large bowel that gives our bodies energy.

theodp writes: The Education Revolution will be patented. USPTO records show that Khan Academy is seeking a patent for Systems and Methods for Split Testing Educational Videos. From the patent application: "Systems and methods are provided for comparing different videos pertaining to a topic. Two different versions of an educational video may be compared using split comparison testing. A set of questions may be provided along with each video about the topic taught in the video. Users may view one of the videos and answer the questions. Data about the user responses may be aggregated and used to determine which video more effectively conveys information to the viewer based on the question responses." Now it's up to the USPTO to decide if something like the test and control studies conducted 40+ years ago (pdf) by the PLATO system to measure the effectiveness of different teaching methods would count as prior art. In response to an earlier post on Khan Academy's pending patents on learning computer programming and 'social programming,' Slashdot user Khan Academy said that the nonprofit is using patents for good, so not to worry.

nojayuk writes: The world's last operating Magnox nuclear reactor, Wylfa 1 in Anglesey, Wales was closed yesterday after providing carbon-free power for over 40 years. Wylfa1 was originally scheduled to shut in 2012 along with the adjacent Wylfa 2 reactor but it was kept operating for another three years with the innovative use of partially-burnt fuel from Wylfa 2 and remaining stocks of fresh Magnox fuel. The reactor will be defuelled and move into its decommissioning phase over the next year. The Magnox design used gas-cooling and a carbon moderator with the capability to produce weapons-grade plutonium depending on how it was fuelled and operated. Its design fed into the next-generation AGRs which provide about 6GW of Britain's electricity supply today.

HughPickens.com writes: Ben Sisario writes at the NYT that Discogs has built one of the most exhaustive collections of discographical information in the world, and with 24 million items for sale, (eBay's music section lists 11 million) Discogs is on track to do nearly $100 million in business by the end of the year. One of Discog's secrets is the use of Wikipedia's model of user-generated content with historical data cataloged by thousands of volunteer editors in extreme detail. The site's entry for the Beatles' White Album, for instance, contains 309 distinct versions of the record, including its original releases in countries like Uruguay, India and Yugoslavia — in mono and stereo configurations — and decades of reissues, from Greek eight-tracks to Japanese CDs. "There's a record-collector gene," says Kevin Lewandowski. "Some people want to know every little detail about a record."

The site, once run from a computer in Lewandowski's closet and originally restricted to electronic music, has grown rapidly. "It took about six months working nights and weekends on Discogs, and I launched it in November 2000. It was very simplistic compared to what it is now, but it started growing right away." Discogs now has 37 employees around the world, 20 million online visitors a month and three million registered users. Lewandowski, who is the sole owner of Discogs, says he had no interest in selling the business. He has watched other players enter the field over the last 15 years, including Amazon, which in 2008 introduced SoundUnwound, a Wikipedia-like site for music that was quietly shut down four years later. Discogs may have survived because of the innovation of its marketplace, giving collectors an incentive to expand the database with every imaginable detail. "I want it to go on forever," says Lewandowski.

HughPickens.com writes: Jad Mouawad writes at the NYT that a driver's license may no longer be enough for airline passengers to clear security in some states, if the Department of Homeland Security has its way the Department of Transportation will start enforcing the Real ID Act, which was enacted by Congress in 2005 following the recommendations of the 9/11 Commission. Homeland Security officials insist there will be no more delays. In recent months, federal officials have visited Minnesota and other states to stress that the clock was ticking. The message was that while participation was voluntary, there would be consequences for failing to comply. "The federal government has quietly gone around and clubbed states into submission," says Warren Limmer, a state senator in Minnesota and one of the authors of a 2009 state law that prohibits local officials from complying with the federal law. "That's a pretty heavy club."

Privacy experts, civil liberty organizations and libertarian groups fear the law would create something like a national identification card. Presently twenty-nine states are not in compliance with the act and more than a dozen have passed laws barring their motor vehicle departments from complying with the law, according to the National Conference of State Legislatures. The new standards require more stringent proof of identity and will eventually allow users' information to be shared more easily in a national database. Marc Rotenberg, the president of the Electronic Privacy Information Center,says he is concerned with all the information being available on the cards in a way that makes it more shareable and notes that the recent theft of millions of private records from the Office of Personnel Management did not inspire confidence in the government's ability to maintain secure databases. "You create more risk when you connect databases,"says Rotenberg. "One vulnerability becomes multiple vulnerabilities."

JustAnotherOldGuy writes: Peter "brokep" Sunde, co-founder of The Pirate Bay, has built a machine that makes 100 copies per second of Gnarls Barkley's "Crazy," storing them in /dev/null (which is of course, deleting them even as they're created). The machine, called a "Kopimashin," is cobbled together out of a Raspberry Pi, some hacky python that he doesn't want to show anyone, and an LCD screen that calculates a running tally of the damages he's inflicted upon the record industry through its use. The 8,000,000 copies it makes every day costs the record industry $10m/day in losses. At that rate, they'll be bankrupt in a few weeks at most.

HughPickens.com writes: Scott Shane writes in the NY Times that the National Archives and Records Administration has released a detailed list of the United States' potential targets for atomic bombers in the event of war with the Soviet Union, showing the number and the variety of targets on its territory, as well as in Eastern Europe and China. The Strategic Air Command study includes chilling details. According to its authors, their target priorities and nuclear bombing tactics would expose nearby civilians and "friendly forces and people" to high levels of deadly radioactive fallout. Moreover, the authors developed a plan for the "systematic destruction" of Soviet bloc urban-industrial targets that specifically and explicitly targeted "population" in all cities, including Beijing, Moscow, Leningrad, East Berlin, and Warsaw.

The target list was produced at a time before intercontinental or submarine-launched missiles, when piloted bombers were essentially the only means of delivering nuclear weapons. The United States then had a huge advantage over the Soviet Union, with a nuclear arsenal about 10 times as big. "We've known the general contours of nuclear war planning for a few decades," says Stephen I. Schwartz. "But it's great that the details are coming out. These are extraordinary weapons, capable of incredible destruction. And this document may be history, but unfortunately the weapons are not yet history."

hypnosec writes: Oak Ridge National Laboratory has successfully produced 50 grams of plutonium-238, an isotope that produces heat without a lot of other, problematic radiation. This makes it suitable for use in radioisotope thermoelectric generators, which can power space probes. The new sample effectively revives the U.S.'s end-to-end plutonium-238 production capabilities, which have been dormant for around 30 years since work was stopped at the Savannah River Plant in South Carolina. The ORNL is optimistic this important milestone will pave the way for regular production of the material, ensuring constant supply for NASA's future missions.

The probe will be in service for three years to observe the direction, energy and electric charge of high-energy particles in space in search of dark matter. Two further missions will blast off next year: the world's first quantum-communications satellite and an X-ray telescope observing in a unique energy band. Together, these missions mark a new start for space science in China which previously focused on non-science missions, says Wu Ji, director-general of the National Space Science Centre (NSSC).

New submitter rafaelj writes: Apparently, Tim Berners Lee was not aware of the real impact on internet freedom in Brazil when he supported the Marco Civil to pass in the Brazilian congress last year. Using the Brazilian Civil "Rights" Framework, a minor Brazilian court ordered WhatsApp service to be suspended in the whole country after WhatsApp refused to provide user's data. The order was happily accomplished by the Brazilian mobile phone companies as they have been lobbying to convince the government to regulate the service in Brazil since their profits are decreasing steadily after Brazilians started using WhastsApp instead of (tolled) SMS and phone calls. Brazil has the most expensive cell phone rates on the planet. Adds readers André Costa: The ban is a result of WhatsApp failing to comply with two previous court orders, on July 23 and August 7. Even though [the ban] affects millions of users, the service of course remains accessible through Wi-Fi. The plaintiff's identity is being kept secret. The news has already spread worldwide). The ban on WhatsApp resulted in more than 1.5 million users joining its competitor Telegram.

subh_arya writes: Researchers from NYU, UToronto and MIT have come up with a technique that captures human learning abilities for a large class of simple visual concepts to recognize handwritten characters from World's Alphabet. Their computational model (abstract) represents concepts as simple programs that best explain observed examples under a Bayesian criterion. Unlike recent deep learning approaches that require thousands of examples to train an efficient model, their model can achieve human-level performance with only one example. Additionally, the authors present several "visual Turing tests" probing the model's creative generalization abilities, which in many cases are indistinguishable from human behavior.

The L.A. Times reports that researchers using the Kepler and Spitzer space telescopes have discovered an astronomical first: a low-mass star with a huge, persistent, swirling surface feature akin to the long-lived storm on Jupiter. The star, W1906+40 , is cool enough ("a mere 3,500 degrees Fahrenheit or so") to allow cloud formation. A slice: This star was first spotted by NASA's Wide-field Infrared Survey Explorer (or WISE) in 2011; study leader John Gizis of the University of Delaware, Newark and colleagues then looked through NASA's Kepler data to further examine the star. (It just so happened that Kepler was pointing in the right direction to spot the L-dwarf.) ... "The long life of the cloud is in contrast with weather changes seen in cooler brown dwarfs on the timescale of hours and days," they wrote. In fact, the researchers believe the storm has been going strong for at least two years — a stability they seemed to find slightly baffling. "Evidently the W1906+40 spot is very long-lived compared to the 'weather' features in cooler L and T dwarfs," they wrote. "Why would the clouds in W1906+40 be stable?"

The Department of Homeland Security is said to have put up the single engine craft over the California city and ordered it to make repeated circles overhead. The craft would likely have been equipped with Dirtbox technology which can scan tens of thousands of phones in one go to identify suspects. The report adds to the intrigue about whether or not there were accomplices in the San Bernardino attacks, which took place last Wednesday and were the worst terrorist attack on American soil since 9/11.

StartsWithABang writes: If you calculate the forces between two fundamental particles separated by subatomic distances, you find that the strong, electromagnetic or weak nuclear force could all be the strongest, dependent on the particulars of your setup. But throw gravity in there, and it turns out to be weaker by some 40 orders of magnitude. This discrepancy, that gravity is such an oddball, is known as the hierarchy problem, and is by many measures the greatest unsolved problem in theoretical physics. Yet the new, upgraded run of the LHC has the potential to uncover any one of four possible solutions, some of which we have hints for already.

New submitter Maury Markowitz writes: Star Raiders was the Atari 8-bit home computer's killer app, inspiring Ted Nelson to claim that "The Atari machine is the most extraordinary computer graphics box ever made, and Star Raiders is its virtuoso demonstration game." It was not until many years later that a sequel, of sorts, was released. This Star Raiders II was nothing at all like the original, as it was originally The Last Starfighter, a licensed tie-in to that was rebranded to avoid the stench of the box-office flop.

Well now, three decades later, Kevin Savetz of the excellent ANTIC podcast has dropped a bomb on the retrogaming community: there was a real Star Raiders II under construction for a long time, but it disappeared as Atari imploded. Kevin tracked down the author, Aric Wilmunder, and convinced him to release it after all these years. You can download the game for the emulator of your choice, and read the manual and backstory on the Internet Archive.

So it's probably not too surprising that Wolfram's new book, An Elementary Introduction to the Wolfram Language (free on the web), aspires to teach those new to programming how to do much more than just move Minecraft and Star Wars characters around. "The goal of the book," explains Wolfram in a blog post, "is to take people from zero to the point where they know enough about the Wolfram Language that they can routinely use it to create programs for things they want to do. And when I say 'zero', I really mean 'zero'. This is a book for everyone. It doesn't assume any knowledge of programming, or math (beyond basic arithmetic), or anything else. It just starts from scratch and explains things. I've tried to make it appropriate for both adults and kids. I think it'll work for typical kids aged about 12 and up."

HughPickens.com writes: Dave Phillipps has an interesting article in the NY Times about B-52's and why the Air Force's largest bomber, now in its 60th year of active service and scheduled to fly until 2040, are not retiring anytime soon. "Many of our B-52 bombers are now older than the pilots who fly them," said Ronald Reagan in 1980. Today, there is a B-52 pilot whose father and grandfather flew the plane. Originally slated for retirement generations ago, the B.U.F.F. — a colorful acronym that the Air Force euphemistically paraphrases as Big Ugly Fat Fellow — continues to be deployed in conflict after conflict. It dropped the first hydrogen bomb in the Bikini Islands in 1956, and laser-guided bombs in Afghanistan in 2006. It has outlived its replacement. And its replacement's replacement. And its replacement's replacement's replacement. The unexpectedly long career is due in part to a rugged design that has allowed the B-52 to go nearly anywhere and drop nearly anything the Pentagon desires, including both atomic bombs and leaflets. But it is also due to the decidedly underwhelming jets put forth to take its place. The $283 million B-1B Lancer first rolled off the assembly line in 1988 with a state-of-the-art radar-jamming system that jammed its own radar. The $2 billion B-2 Spirit, introduced a decade later, had stealth technology so delicate that it could not go into the rain. "There have been a series of attempts to build a better intercontinental bomber, and they have consistently failed," says Owen Coté. "Turns out whenever we try to improve on the B-52, we run into problems, so we still have the B-52."

The usefulness of the large bomber — and bombers in general — has come under question in the modern era of insurgent wars and stateless armies. In the Persian Gulf war, Kosovo, Afghanistan and the Iraq war, the lumbering jets, well-established as a symbol of death and destruction, demoralized enemy ground troops by first dropping tons of leaflets with messages like "flee and live, or stay and die," then returning the next day with tons of explosives. In recent years, it has flown what the Air Force calls "assurance and deterrence" missions near North Korea and Russia. Two B-52 strategic bombers recently flew near artificial Chinese-built islands in the South China Sea and were contacted by Chinese ground controllers but continued their mission undeterred. "The B.U.F.F. is like the rook in a chess game," says Maj. Mark Burleys. "Just by how you position it on the board, it changes the posture of your adversary."

Although many developers prefer developing in C/C++ using GCC, developer David Bolton (in a new Dice article) makes an argument for why you should switch to Clang. While GCC is probably still best when it comes to speed, he argues, Clang is improving release by release, and features tools that developers could find useful.

Alternatively: spaceships sheltering from detection behind an asteroid, or dodging asteroids, or pretty much anything else involving asteroids that don't look like [a pock-marked potato]." Another big red flag for Stross is when authors fail to appreciate Newton's second law, having their characters undergo impacts or accelerations that would turn them into a thin, reddish paste on their starship's hull. Some interesting examples from commenters include: futuristic yet manually-aimed weapons, technobabble as a plot device, and science officers with Ph.D. levels of expertise in dozens of fields.

HughPickens.com writes: 75% of the Earth's population, i.e. four billion people, effectively "don't exist" to modern computer systems because they have no physical address. The "unaddressed" can't open a bank account, can't deal properly with a hospital or an administration, and can even struggle to get a delivery. Now Frédéric Filloux writes at Monday Note that What3Words, a London startup, is seeking to solve this problem by providing a combination of three words, in any language, that specify every 3-meter by 3-meter square in the world. Each square has a 3-word address that can be communicated quickly, easily and with no ambiguity. Altogether, 40,000 words combined in triplets label 57 trillion squares. Thus far, the system has been built in 10 languages: English, Spanish, French, German, Italian, Swahili, Portuguese, Swedish, Turkish and, starting next month, Arabic. All together, this lingua franca requires only 5 megabytes of data, small enough to reside in any smartphone and work offline. Each square has its identity in its own language that is not a translation of another.

Messy addressing systems have measurable consequences. UPS, the world's largest parcel delivery provider, calculated that if its trucks merely drove one mile less per day, the company would save $50m a year. In United Kingdom, bad addressing costs the Royal Mail £775m per year. "One might say latitude and longitude can solve this. Sure thing. Except that GPS coordinates require 16 digits, 2 characters (+/-/N/S/E/W), 2 decimal points, space and comma, to specify a location of the size of a housing block," writes Filloux. "Not helpful for a densely populated African village, or a Mumbai slum." The system is already being used to deliver packages in the favelas in Brasil with Cartero Amigo, solar lights to the Slums in India with Pollinate-Energy and mosquito traps in Tanzania with in2care. For What3Words, the decisive boost will come from its integration in major mapping suppliers such as Google Maps or Waze.

"He remains completely free to do as he wishes with his money," writes Eisinger. "That's what America is all about. But as a society, we don't generally call these types of activities 'charity.'"

A charitable foundation is subject to rules and oversight. It has to allocate a certain percentage of its assets every year. The new Zuckerberg LLC won't be subject to those rules and won't have any transparency requirements. According to Eisinger what this means is that Zuckerberg has amassed one of the greatest fortunes in the world — and is likely never to pay any taxes on it. "Instead of lavishing praise on Mr. Zuckerberg for having issued a news release with a promise, this should be an occasion to mull what kind of society we want to live in," concludes Eisinger. "The point is that we are turning into a society of oligarchs. And I am not as excited as some to welcome the new Silicon Valley overlords."

Thousands of planetary candidates emerged via the transit method, where periodic dips of 3% or less were noted with regularity. However, a follow-up study has come out on the giant exoplanets, finding that over 50% of them aren't giant planets after all, but wound up being eclipsing binary stars. Perhaps our lone star Solar System is the oddity, after all.

trbdavies writes: Reporting from the CRISPR (clustered regularly interspaced short palindromic repeats) gene-editing summit in D.C., the Washington Post quotes Harvard genetics professor George Church as expressing "confidence that in just five or six years he will be able to reverse the aging process in human beings." He says: "A scenario is, everyone takes gene therapy — not just curing rare diseases like cystic fibrosis, but diseases that everyone has, like aging," CRISPR is a powerful technology, but many at the summit have expressed caution about both the ethics and the feasibility of using it to cure disease. The story quotes Klaus Rajewsky, of the Max Delbruck Center for Molecular Medicine saying "We have become masters in the art of manipulating genes, but our understanding of their function and interaction is far more limited."

We all know (or know about) Richard M. Stallmann, founder of and vociferous spokesman for the Free Software Foundation. But the organization is far from a one-man band, and Donald Robertson, their copyright administrator (and wearer of several other hats as well) is the person to turn to when you want to get into the murky depths of copyright and patent law. He's also somewhat of an expert on the Trans Pacific Partnership (TPP), which the FSF says, '...has a number of truly dangerous provisions that harm software freedom."

What can you do to help stop this trade agreement that has gotten the FSF (and the EFF, among others) up in arms? Don answers that question in the video (and accompanying transcript for those who would rather read than watch). And any unanswered questions will probably be taken care of in a second video interview with Mr. Robertson that we plan to run in the next day or two.

An anonymous reader sends word that a three-day summit has begun in Washington to discuss the future of genetic engineering. It has a particular focus on the CRISPR technique, which has made gene editing quicker and more robust than ever before. "The reason CRISPR is so controversial is that it works well on 'germline' cells, such as sperm, eggs and embryonic cells, and the genetic editing results in heritable traits. Many scientific organizations have called for a time-out on any experiments on human cells, fearing that this crosses into dicey ethical territory. This meeting in Washington could potentially generate a new call for restraint, or some guidelines in how to handle the explosive technology." Many scientists, lawyers, and policymakers are present at the summit to try to reach consensus on how the scientific community should proceed with such research, and how the fruits of their research should be used. Professor Alta Charo said, "The more we can have effective systems for responsible oversight for the development and deployment of a technology, the more we can take chances. We have the chance to back up at the end, and change course."

A few weeks ago you had a chance to ask author, entrepreneur, and software developer Jeff Atwood about founding Stack Overflow and the Stack Exchange Network, as well as his new endeavor, the Discourse open-source discussion platform. Below you will find his answers to your questions. Magic wand
by Anonymous Coward

If you had a magic wand to make one change in technology right now, what would it be?

Atwood: Users would not have to generate, remember, enter, or ever think about passwords again. Computers would automatically know who the user is through a combination of ambient biometrics plus physical possession of some kind of device. Like, say, a smartphone.

Passwords are the enemy. And the users, because we are the idiots put in charge of making up the passwords. But mostly, it's the *goddamn passwords*.



Why did you choose Microsoft Platform for SE?
by Sadsfae

I don't see many large, high profile sites running an entire Microsoft Windows stack nowadays (IIS/SQL Server, etc) but Stack Exchange is one of them.

What were the reasons behind choosing a full Microsoft stack versus any of the Open Source alternatives which seem much more prevalent, especially in start-ups and smaller businesses for web presence?

Atwood: Mostly, C# is what I knew and what I was skilled in -- and I'm a great fan of its primary architect Anders Hejsberg who also created Turbo Pascal and Delphi. Performance was a goal, too, and since C# is a compiled language it's *extremely* fast. I think you can see for yourself that Stack Overflow is absurdly fast. Having switched to Ruby with the Discourse project, I can also testify that Ruby .. is, uh ... not ... absurdly fast.

The only downside of the .NET environment is, honestly, the SQL Server licensing costs which can be quite extreme at scale. There is movement to make .NET more open source. Plus the long running mono effort.

The main weakness of .NET is that it's not great for open source projects, though that has changed a bit over the last few years. It never really made sense to open source Stack Overflow -- ask yourself, how many Stack Overflow clones have flourished? Why is that? As a closed source project, the performance, great language design, and scaling of C# worked for us.

I made different choices for Discourse which *was* designed to be an open source project, a tool that is widely applicable to many communities, from day zero.



History of StackExchange
by unencode200x

A question on the history of Stack Exchange. What was the original idea that drove you to make StackExchange and how has it evolved or added since?

Atwood: Do you remember a site called Experts-Exchange? No? That means we succeeded at our original goal.

The basic concept was to do a 100% community driven Q&A that had elements of:

- Wikipedia (all the articles are always up to date and not dead tombstones from six years ago).
- Reddit (voting up the good information and voting down the bad information).
- Blogs (ownership, curation, and responsibility for content that has your name on it).
- Videogames (the Xbox 360 Achievements system, points, and ways of encouraging and incentivizing positive community behavior that are fun).

Where everything we build together is creative commons, and belongs to all of us, since you guys and gals are the ones doing all the work in the system!



Reputation mechanisms & scientific quality
by Anonymous Coward

Jeff, have you thought about how to use reputation mechanisms to improve the quality of published scientific results? I'm asking in the context of John P. A. Ioannidis' famous paper.

It seems to me one fix for this (horrible) problem might be an online reputation mechanism where scientists could rate the reproducibility of published results. Thoughts? (thanks for inventing Stack Exchange - you've done the world a big favor).

Atwood: It certainly seems applicable. The Stack engine works best for systems of data, fact, and science -- or at least a "tome of knowledge" -- where you can actually verify an answer (or five answers) as plausibly correct. You can see which topics do best on the Stack engine in the Stack Exchange directory, with a massive, Jupiter sized Stack Overflow right at the top.

There's always more than one way to do it, of course, but when you start getting dozens or hundreds of "answers" you don't have Q&A, you have a discussion with no clear answers, just opinions.



User Reputation, Moderating, and Discourse
by T.E.D.

I think its probably inarguable that the biggest innovation StackOverflow brought to the web was the centrality of reputation and user moderation to its design. Sure, our own /. had done something similar years before, and it was hardly the first either, but no website I know of had before taken it to its logical conclusion in quite the way SO does. This effectively "crowdsourced" a lot of traditional website administrative activities, which turned out to be an incredibly powerful idea. Practically all the functionality of SO is built around the concept.

So when I saw you were tackling online message boards, I expected the same kind of thing. But browsing around a typical Discourse thread, I'm not seeing that at all. Sure, users can "heart" posts, but all that does is bump a small counter next to the heart. There is no way to tell at a glance which posts users found the best and/or worst. Higher rated posts don't sort to the top, or get bigger or anything. As a result, I don't even see that feature used much. Certainly its nothing like SO, where post voting is the central activity. It also seems like moderation on Discourse is designed to be done by administrators, not users. I don't see any facility for users getting moderation privs as they gain reputation. Compared to SO, Discourse seems kind of, well, like a big step backwards in interactivity.

I'm sure I'm missing something here. What is it? Or did you really decide SO's centering of its design around users and their opinion on posts was a mistake, or perhaps just not a good fit for a more generalized discussion board?

Atwood: Sorting a conversation by votes is a pretty effective way to destroy conversation. How can you follow the logical flow of back and forth, chronological dialog when the ground is constantly shifting underneath you as posts get voted up or down? You can't.

Stack is a system of technical Q&A, where opinions are fascinating, and all, but they are completely trumped by facts, data, and science. Stack only tolerates the minimum amount of discussion necessary to get the best questions and the best answers. The goal isn't for people to talk to each other, the goal is for people to *answer the damn question*. Ideally with the aforementioned facts, data, and science, so our peers can objectively decide if the answer is correct and works.

Discourse, on the other hand, is explicitly a system of discussion and opinion. There is no right and wrong. You can't tell me my opinion that Wolverine is the coolest X-Man is wrong. Long after people have forgotten what exactly was said, they will remember how you made them feel. That's what the like (heart) action is about, and why it is featured so prominently: empathy. Discourse is a system of empathy.

We do have user trust levels in Discourse, it's just less obvious, because we're playing a different kind of game. Compare that with Stack, where your reputation number and badge counts appear prominently next to your name every time you post. Trust me, people *do* notice when you like their post. And if they see your post got 20 likes whereas their post only got two, or none, they absolutely notice that too. Discourse is more of a collaborative game, where Stack is an explicitly competitive game, and that's why the score is so prominent. The best way to motivate a programmer is to tell them someone else did it better. Don't try to race sheep, don't try to herd race horses.

There may not be re-ordering by votes in Discourse, as there is in Stack Overflow, but there is a summary mode for topics when they reach 50 or more replies. If you'd like to see this in action, visit a longer topic and press the "Summarize Topic" button at the top near the estimated read time, or as I like to call it, the TL;DR button. Then you'll see only the "best" 10 percent of that long topic. That factors in a lot of data from each post such as likes, incoming and outgoing links to the post, the number of times it has been read, total read time (we track actual on-screen read time for all posts in Discourse), number of times it has been bookmarked, number of replies, and so on. You can also expand context above (in reply to) and below (replies) for each post as needed. Or you can expand the collapsed gaps as needed. Try it, you just need a long topic with over 50 replies to see it in action.



Cargo cult programming and Stack Overflow
by Anonymous Coward

I don't mean to minimize StackOverflow's contribution to the online knowledge base, because it's a great tool when used properly. I'm a systems guy and Server Fault is often more useful than vendor support for looking up strange error messages and possible troubleshooting routes. But, there are a lot of low skill programmers and sysadmins out there who lean on these tools way too much. How do you feel about these properties contributing to the crappy cargo cult programming and sysadmin work we see in our field?

Atwood: Stack is a system of peer education at its core. The key insight is realizing that crappy programmers hurt all of us, and it's our job to learn from each other so that we have less terrible code and terrible coders to deal with in the future. Even if that terrible coder is us!

The best way to learn a topic is to teach it to someone else. That is the skill at the heart of the Stack engine. It works at three levels:

1. Selfish. I need the answer to this question or I may get fired. Give me the answer. This is ideally handled through a good search result. They get what they need.

2. Self Improvement. I want to get reputation and prove to my peers that I know what I am doing. The more I learn, the better I am at my job, the more skilled I am, and the more job satisfaction / money / prestige I can gain.

3. Advancement of our craft. Programming, physics, and math will be here long after we are all dead. It's an honor to help move science forward together as much as we can together in our lifetime, so that future programmers, physicists, and mathematicians can stand on our shoulders and do amazing, incredible things for the future of humanity.

It's fine for people to play the game at level one, because they are also helping others learn and work their way up the skill ladder. If someone is learning, and someone is teaching, we all win.



Rampant closure of questions
by WaffleMonster

From time to time I search stackoverflow for easy answers and I would say about 20% of the time the question has been closed even though it is the reason I went to stackoverflow in the first place. In most of these instances a useful answer was also provided before closure. So my question to you is simply what gives.

The most common reason for closure I run into is that the people closing it don't have any domain clue what is being asked and appear to assume if they don't understand nobody else does either.

Another common reason for closure is the "duplicate" question meme in which nuance is overlooked and questions are marked as duplicates because the people doing the marking failed to understand or appreciate the difference. This is very annoying.

Less common but equally annoying issues are closure due to chatter about domain specific algorithms not being "programming questions" or even more amusing someone posting a question that is more specifically addressed by one of a hundred different stack exchanges even though it is still on topic.

Atwood: Remember that Stack is for questions that can be explicitly answered, *not* discussion. It's not a place for "what's the best way to.." opinion sinkholes. Humans love this kind of stuff because they are social animals, and there's nothing wrong with wanting to have a discussion -- you just need to have that discussion elsewhere, because you can't have it on Stack Overflow.

We're strict about this because we've seen what happens when systems are not explicit about their goals. This way lies madness. This way lies Yahoo Answers. In Stack's case the goal is *learning*. And I do not mean accidental, random, meandering, oh-hey-check-out-this-crazy-thing-I-saw-on-Reddit learning, but highly efficient, directed learning where you are a classroom, not a social club.

Duplicates are a hard problem, for sure. That's the one place I felt we didn't make a ton of progress in my four years there, unfortunately. Human beings have the incredibly annoying habit of asking the same questions using completely and utterly different words. They're really good at it. And it is true that over time there are more and more questions and answers on Stack Overflow, so the minefield of "is this a duplicate of...?" is only getting bigger over time. It is a super hard problem. If you have specific ideas of how to handle duplicates better, don't hesitate to ask or search some of the existing topics there.

Remember, Stack Overflow is governed by programmers just like you, you are a citizen of its community just like me, and you get a say in what happens there. You could even be elected a moderator by participating in the yearly elections. So if you don't like the way things work, it's like any other democracy -- make your voice heard, vote, campaign, or run for office.



Relevance of old answers
by Scottingham

As SO ages, some of the offered solutions are no longer valid. Are there currently plans to automate some way of validating old answers automatically? This problem seems to be a larger problem with forums in general. Do you have any musings regarding aging forums?

Atwood: Anyone, even anonymous users, can suggest an edit to any question or answer on any Stack Exchange site. It is like Wikipedia in that regard. Once two other users with sufficient reputation approve the edit it goes through. Alternately, if you earn enough reputation, you can make direct edits yourself.

If you see information that's out of date, edit it to make it more up to date! Be the change you want to see, and all that.



Signal To Noise: Trolls
by Anonymous Coward

In reading your work for years and seeing your various contributions, it seems like you are fascinated with filtering out the most useful information. In many of your blog posts the insight is not yours but rather a conglomeration of chosen useful quotes and sources. I very much appreciate this. My question for you is how do you handle critical feedback vs trolls when dealing with communities. For example, the down button is often a disagree button rather than a negative point. How do you deal with mixed opinions?

To use a real life personal example, TEF noted how he felt you were suggesting that people shouldn't play around to learn. Yet, the way he said it was clearly inflammatory. How do you separate the legitimate concern and critical feedback from the troll who doesn't want to listen to your response?

Atwood: There is a reason we don't have a "dislike" or "downvote" in Discourse. How can an opinion be wrong? It can be rude, offensive, misinformed, misguided, or just plumb crazy -- but it can't be objectively *wrong*. Often the way you judge posts in Discourse is by their *lack* of likes. If nobody feels strongly enough about your reply to push the heart button on it, and 'co-sign' it with their name in public, that says something.

As for separating legitimate criticism from trolling, I don't know that actual trolls, by the strict definition of the word troll, are that common. I think bad faith makes itself quite clear in the tone and delivery of the criticism. Are you saying this in the hope that we can both learn something from the interaction, or are you saying it because you want to hurt or shame or denigrate or discredit me? Truth alone, as it turns out, isn't the whole truth. How you say something matters.

Bad faith is especially visible to the audience, who has no stake in the argument, and can be surprisingly objective in judging authenticity. One of the most striking things about the early days of Stack Overflow was seeing how people would not upvote cruelty. They wouldn't necessarily downvote it, mind you, but overt cruelty and meanness in an answer was never an effective way to get upvotes and reputation even if the technical information was sound. The best way to win an argument isn't to convince the other person, necessarily -- good luck with that -- but to convince everyone who is watching. And you will never convince an audience watching you be cruel to another person.

In life, being cruel to others may achieve some short term goals, but it is *never* a winning long term strategy. And I think that is exactly how it should be.



How do you have a good debate online?
by AmiMoJo

It seems like the internet is mostly a terrible place to have debates. Many forums quickly become echo chambers for people who want to be as offensive as possible just to prove that they can exercise their free speech rights. Other times debates are derailed by cheap tactics like being deliberately offensive to derail the arguments and bog everyone down in accusations that they are "SJWs". Ad-hominems and obvious logical fallacies seem to be the norm.

How do you plan to avoid this happening? So far no-one seems to have found a way.

Atwood: We have a few tricks up our sleeve at Discourse. We try to teach communities not just how the software works, but how human beings should work, with stuff like our Universal Rules of Civilized Discourse which is prominently featured in every install of Discourse and of course Creative Commons licensed.

I believe in the “Just in Time" theory of human behavior where we try to reach you at the exact moment you start typing your first post with the TL;DR version of those rules. And the most important rule of all for empathy is a simple one: hey, there's another person on the other side of that screen. Not just an abstract name, an avatar, a collection of pixels, but a real live human being, just like you.

I don't know if we can weaponize empathy but I'd sure like to try. Not every space has to be open to everyone, unless you work for Facebook or Twitter. Sometimes the point of having your own community is being able to close the door on people who demonstrate that they can't behave themselves in your house. Live with wolves, and you learn to howl.



Stackoverflow in hindsight
by jez9999

In hindsight, would you have reduced the scope of on-topic questions for Stackoverflow to where it's at today when you started the site knowing what you do now, and do you think it would've made the site less popular?

Atwood: Much of the strictness of Stack Overflow evolved as a side effect of the reputation system. Once you have a reputation score, you want to protect that score, and nothing devalues your own reputation more than seeing some other programmer get 300 reputation points from a humorous answer containing nothing but an XKCD comic. Anyone can post an XKCD comic; that takes no particular competence or knowledge. So the evolution in strictness -- peer reputation should come from expression of *skill*, not funny anecdotes -- was largely driven by the community, not by anyone employed at Stack Overflow.

Even knowing what I already knew, which is that putting a number next to someone's name will cause them to do whatever it takes to make that number go up -- I didn't anticipate how strong this effect would be. But ultimately I agree with it, and I think systems should trend to slightly increasing strictness over time as they grow bigger. Big cities have different problems than small cities, and they need more structure.

HughPickens.com writes: Peter Thiel writes in the NYT that what's especially strange about the failed push for renewables is that we already had a practical plan back in the 1960s to become fully carbon-free without any need of wind or solar: nuclear power. "But after years of cost overruns, technical challenges and the bizarre coincidence of an accident at Three Mile Island and the 1979 release of the Hollywood horror movie "The China Syndrome," about a hundred proposed reactors were canceled," says Thiel. "If we had kept building, our power grid could have been carbon-free years ago. Instead, we went in reverse."

According to Thiel, a new generation of American nuclear scientists has produced designs for better reactors. Crucially, these new designs may finally overcome the most fundamental obstacle to the success of nuclear power: high cost. Designs using molten salt, alternative fuels and small modular reactors have all attracted interest not just from academics but also from entrepreneurs and venture capitalists like me ready to put money behind nuclear power. However, none of these new designs can benefit the real world without a path to regulatory approval, and today's regulations are tailored for traditional reactors, making it almost impossible to commercialize new ones. "Both the right's fear of government and the left's fear of technology have jointly stunted our nuclear energy policy," concludes Thiel. "supporting nuclear power with more than words is the litmus test for seriousness about climate change. Like Nixon's going to China, this is something only Mr. Obama can do. If this president clears the path for a new atomic age, American scientists are ready to build it."

During a NATO wargame in November, 1983, that software met all conditions necessary to forecast the beginning of a nuclear war. "Many of these procedures and tactics were things the Soviets had never seen, and the whole exercise came after a series of feints by U.S. and NATO forces to size up Soviet defenses and the downing of Korean Air Lines Flight 007 on September 1, 1983. So as Soviet leaders monitored the exercise and considered the current climate, they put one and one together. Able Archer, according to Soviet leadership at least, must have been a cover for a genuine surprise attack planned by the U.S., then led by a president possibly insane enough to do it." Fortunately, when the military exercise ended, so did Soviet fears that an attack was imminent.

HughPickens.com writes: Brad Tuttle reports at Money Magazine that while the terms "Black Friday" and "Cyber Monday" are more ubiquitous than ever, the importance of the can't-miss shopping days is undeniably fading. Retailers seem to want it both ways: They want shoppers to spend money long before these key shopping events, and yet they also want shoppers to turn out in full force to make purchases over the epic Black Friday weekend. When they use the "Cheap Stuff!" card day after day and week after week, the deals on any single day stop seeming special. Add to that the trend of manufacturers creating stripped-down versions of their electronics to sell on Black Friday, and consumers have less reason than ever to flood retail stores.

The true story behind Black Friday is not as sunny as retailers might have you believe. Back in the 1950s, police in the city of Philadelphia used the term to describe the chaos that ensued on the day after Thanksgiving, when hordes of suburban shoppers and tourists flooded into the city in advance of the big Army-Navy football game held on that Saturday every year. Shoplifters would also take advantage of the bedlam in stores to make off with merchandise, adding to the law enforcement headache. Sometime in the late 1980s, however, retailers found a way to reinvent Black Friday and turn it into something that reflected positively, rather than negatively, on them and their customers. The result was the "red to black" concept of the holiday mentioned earlier, and the notion that the day after Thanksgiving marked the occasion when America's stores finally turned a profit.

HughPickens.com writes: Murtaza Hussain writes at The Intercept that although it remains in use at sensitive security areas throughout the world, the ADE 651 is a complete fraud and the ADE-651's manufacturer sold it with the full knowledge that it was useless at detecting explosives. There are no batteries in the unit and it consists of a swivelling aerial mounted to a hinge on a hand-grip. The device contains nothing but the type of anti-theft tag used to prevent stealing in high street stores and critics have likened it to a glorified dowsing rod.

The story of how the ADE 651 came into use involves the 2003 U.S. invasion of Iraq. At the height of the conflict, as the new Iraqi government battled a wave of deadly car bombings, it purchased more than 7,000 ADE 651 units worth tens of millions of dollars in a desperate effort to stop the attacks. Not only did the units not help, the device actually heightened the bloodshed by creating "a false sense of security" that contributed to the deaths of hundreds of Iraqi civilians. A BBC investigation led to a subsequent export ban on the devices.

The device is once again back in the news as it was reportedly used for security screening at hotels in the Egyptian resort city of Sharm el-Sheikh where a Russian airliner that took off from that city's airport was recently destroyed in a likely bombing attack by the militant Islamic State group. Speaking to The Independent about the hotel screening, the U.K. Foreign Office stated it would "continue to raise concerns" over the use of the ADE 651. James McCormick, the man responsible for the manufacture and sale of the ADE 651, received a 10-year prison sentence for his part in manufacture of the devices, sold to Iraq for $40,000 each. An employee of McCormick who later became a whistleblower said that after becoming concerned and questioning McCormick about the device, McCormick told him the ADE 651 "does exactly what it's designed to. It makes money."
