Long-time Slashddot reader Rei writes: On the face of it, sodium seems like about the worst thing you could make a wire out of — it oxidizes rapidly in air, releases hot hydrogen gas in water, melts at 97.8 degrees Centigrade, and has virtually no tensile strength. Yet, in the late 1960s and early 1970s, the Nacon Corporation did just that — producing thousands of kilometers of high-gauge sodium wiring for electrical utilities — and it worked surprisingly well.

While sodium has three times the (volumetric) resistivity of copper and nearly double that of alumium, its incredibly low density gives it a gravimetric resistivity less than a third of copper and half of alumium. Priced similar to alumium per unit resistivity (and much cheaper than copper), limitless, and with almost no environmental impact apart from its production energy consumption, sodium wiring proved to be much more flexible without the fatigue or installation damage risks of alumium. The polyethylene insulation proved to offer sufficient tensile strength on its own to safely pull the wire through conduits, while matching its thermal expansion coefficient. The wiring proved to have tamer responses to both over-current (no insulation burnoff) and over-voltage (high corona inception voltage) scenarios than alumium as well. Meanwhile, "accidental cutting" tests, such as with a backhoe, showed that such events posed no greater danger than cutting copper or alumium cabling. Reliability results in operation were mixed — while few reliability problems were reported with the cables themselves, the low-voltage variety of Nacon cables appeared to have unreliable end connectors, causing some of the cabling to need to be repaired during 13 years of utility-scale testing.

Ultimately, it was economics, not technical factors, that doomed sodium wiring. Lifecycle costs, at 1970s pricing, showed that using sodium wiring was similar to or slightly more expensive for utilities than using alumium. Without an unambiguous and significant economic case to justify taking on the risks of going larger scale, there was a lack of utility interest, and Nacon ceased production.

Long-time Slashdot reader theodp writes: Architectural Digest on Amazon CEO Jeff Bezos' $80 million New York City bachelor pad: "Jeff Bezos is not only taking over the internet but is also ruling the real-estate world too. It was just revealed that he purchased not one but three Manhattan apartments overlooking Madison Square Park for $80 million. Included in the sale was a three-floor penthouse apartment [video], in addition to the two units below, giving the Amazon founder and CEO the potential to create a palatial 17,000-square-foot, 12-bedroom pad. [...] This is just the billionaire's latest purchase. He already owns an apartment overlooking Central Park, four California homes, and homes in Texas, Washington state, and Washington, D.C."

CNET reports on the prison sentence given to "the YouTuber who reportedly filmed himself tricking a homeless man into eating Oreos filled with toothpaste." Barcelona prankster Kanghua Ren, 21, known to his followers as ReSet, was sentenced on Friday to 15 months in prison for his crime against the "moral integrity" of the homeless man, according to El Pais newspaper. The court also reportedly ordered Ren's YouTube and other social media channels to be shut down for five years and said he must give the victim 20,000 euros ($22,305) in compensation....

Ren was 19 when he filmed the prank in early 2017 after being challenged by one of his 1.2 million followers, according to the Times. He also gave the homeless man a 20 euro bill. Ren called the video just a bad joke, but the judge noted that he earned more than 2,000 euros in ad revenue generated from the video, the Times said.
It's unlikely Ren will actually serve time behind bars, The New York Times reports, because Spanish law usually suspends sentences under two years for first-time offenders.

I loved this story. The Hustle remembers how in 1964 a world-renowned medical professor found a way to beat roulette wheels, kicking off a five-year winning streak in which he amassed $1,250,000 ($8,000,000 today). He noticed that at the end of each night, casinos would replace cards and dice with fresh sets -- but the expensive roulette wheels went untouched and often stayed in service for decades before being replaced. Like any other machine, these wheels acquired wear and tear. Jarecki began to suspect that tiny defects -- chips, dents, scratches, unlevel surfaces -- might cause certain wheels to land on certain numbers more frequently than randomocity prescribed. The doctor spent weekends commuting between the operating table and the roulette table, manually recording thousands upon thousands of spins, and analyzing the data for statistical abnormalities. "I [experimented] until I had a rough outline of a system based on the previous winning numbers," he told the Sydney Morning Herald in 1969. "If numbers 1, 2, and 3 won the last 3 rounds, [I could determine] what was most likely to win the next 3...."

With his wife, Carol, he scouted dozens of wheels at casinos around Europe, from Monte Carlo (Monaco), to Divonne-les-Bains (France), to Baden-Baden (Germany). The pair recruited a team of 8 "clockers" who posted up at these venues, sometimes recording as many as 20,000 spins over a month-long period. Then, in 1964, he made his first strike. After establishing which wheels were biased, he secured a £25,000 loan from a Swiss financier and spent 6 months candidly exacting his strategy. By the end of the run, he'd netted £625,000 (roughly $6,700,000 today).

Jarecki's victories made headlines in newspapers all over the world, from Kansas to Australia. Everyone wanted his "secret" -- but he knew that if he wanted to replicate the feat, he'd have to conceal his true methodology. So, he concocted a "fanciful tale" for the press: He tallied roulette outcomes daily, then fed the information into an Atlas supercomputer, which told him which numbers to pick. At the time, wrote gambling historian, Russell Barnhart, in Beating the Wheel, "Computers were looked upon as creatures from outer space... Few persons, including casino managers, were vocationally qualified to distinguish myth from reality." Hiding behind this technological ruse, Jarecki continued to keep tabs on biased tables -- and prepare for his next big move...

In the decades following Jarecki's dominance, casinos invested heavily in monitoring their roulette tables for defects and building wheels less prone to bias. Today, most wheels have gone digital, run by algorithms programmed to favor the house.

"Ogusers.com -- a forum popular among people involved in hijacking online accounts and conducting SIM swapping attacks to seize control over victims' phone numbers -- has itself been hacked," reports security researcher Brian Krebs, "exposing the email addresses, hashed passwords, IP addresses and private messages for nearly 113,000 forum users." On May 12, the administrator of OGusers explained an outage to forum members by saying a hard drive failure had erased several months' worth of private messages, forum posts and prestige points, and that he'd restored a backup from January 2019. Little did the administrators of OGusers know at the time, but that May 12 incident coincided with the theft of the forum's user database, and the wiping of forum hard drives. On May 16, the administrator of rival hacking community RaidForums announced he'd uploaded the OGusers database for anyone to download for free...

"The website owner has acknowledged data corruption but not a breach so I guess I'm the first to tell you the truth. According to his statement he didn't have any recent backups so I guess I will provide one on this thread lmfao."
Some users of the hijacking forum complained that their email addresses had started getting phishing emails -- and that the forum's owner had since altered the forum's functionality so user's couldn't delete their accounts.

"It's difficult not to admit feeling a bit of schadenfreude in response to this event..." writes Krebs, adding "federal and state law enforcement investigators going after SIM swappers are likely to have a field day with this database, and my guess is this leak will fuel even more arrests and charges for those involved."

In December the breed registry for Thoroughbred horses released their list of the over 42,000 names for currently-registered racehorses. Then research scientist Janelle Shane turned their list into training data for two neural networks, reports Fast Company: It came up with names like She's a Babe, North Storm, Fabulous Charm, Frisky Joe, and Velvet One, which are so good, it's kind of surprising they haven't already been used by the professional horse namers. Of course, not every name was quite as successful. For example, Ginky's Rental, Moretowiththebotterfron, Orcha Shuffleston, Oats and is Fuct, Pat's Glory Dance, Exclusive Bear, and The Madland Cookie. Although if I were a betting man, I would put all my nonexistent trust fund on Snuckles (or maybe Unbridled Dave or Pick's Lilver or maybe Pickle Rake or Rapple Musty. (Look, there's a reason I don't bet).

As an added treat, Shane opted to have a few of the names illustrated by BigGAN, a neural net that generates pictures. Unfortunately, according to Shane, "horse" was not an image option, so Shane used "horse cart" instead, resulting in some very interesting images.
In 2017 Shane trained a neural network on 162,000 Slashdot headlines, coming up with alternate reality-style headlines like "Microsoft To Develop Programming Law" and "More Pong Users for Kernel Project." But for racehorses, Shane points out that there's already a real-world prizewinner named "Cloud Computing" -- so there's obviously room for improvement.

And today the fastest horse in this year's Kentucky Derby was "Maximum Security", who ironically was disqualified for interference for the first time in the race's 145-year history, making the winner a 65-to-1 longshot named "Country House."

CNN tells the story of 24-year-old "social media influencer" Rossi Lorathio Adams II who'd wanted his domain to be the slogan of his social media sites (which at one point had over a million followers on Snapchat, Instagram and Twitter). Unfortunately, that domain was already owned by another man in Iowa -- but Adams came up with a solution: In June 2017, Adams enlisted his cousin to break into the domain owner's home and force him to transfer it. The cousin drove to the domain owner's house and provided a demand note [which contained "a series of directions on how to change an Internet domain name from the domain owner's GoDaddy account to one of Adams' GoDaddy accounts."] After entering the home, the intruder grabbed the victim's arm and ordered him to connect his computer to the internet. He put the firearm against the victim's head and ordered him to follow the instructions.

"Fearing for his life, the victim quickly turned to move the gun away from his head. The victim then managed to gain control of the gun," court records show. The victim shot the intruder multiple times and called the police. The intruder, Adams' cousin Sherman Hopkins Jr., was sentenced to 20 years in prison last year. Now it's Adams' turn. He will remain in custody pending sentencing. He faces a maximum 20 years in prison, a $250,000 fine and three years of supervised release.

Bearhouse shares a new study from the UK's "National Cyber Security Centre," which advises the public on computer security, about the world's most-frequently cracked passwords. It's probably no surprise to the Slashdot readership: people use bad passwords. A recent study of publicly-available "hacked" accounts -- by the UK National Cyber Security Centre -- reveals "123456" was top, followed by the much more secure "123456789" and hard-to-guess "qwerty". If you're a soccer (football) fan, then try "Liverpool" or "Chelsea" -- they'll work in more than half a million cases. Finally, for musicians, Metallica gets beaten down by 50cent, 140k to 190k respectively.
The most common fictional names used as passwords were "superman" (333,139 users), "naruto" (242,749), "tigger" (237,290), "pokemon" (226,947), and "batman" (203,116).

The organization recommends instead choosing three random words as a password -- and also checking "password blacklists" that show passwords that have already been found in past data breaches. (Developers and sysadmins are also advised to implement these checks as part of their rules for which user passwords will be allowed.) The organization also released a file from the "Have I Been Pwned" site containing the top 100,000 passwords.

So what are the top ten most-frequently used passwords?

• 123456
• 123456789
• qwerty
• password
• 111111
• 12345678
• abc123
• 1234567
• password1
• 12345

At a flat-earth conference in May, Mad Mike Hughes will announce details of "an Antarctic expedition with the goal of reaching the edge of the world...to prove once and for all that this Earth is flat." But before that, he's heading for outer space.

An anonymous reader quotes PhillyVoice: If you recognize the name Mad Mike Hughes, it's likely because he strapped himself into a rocket last March and traveled three-tenths of a mile into the heavens in the name of Flat Earth awareness. (See for yourself!) Well, nearly a year to the date after that momentous achievement, the limousine-driving daredevil and gubernatorial candidate has announced he's building upon the lessons learned last year and pushing the limits even further...

We caught up with him Thursday afternoon on the phone from California where he was "putting decals on the rocket right now!" Before any sort of Antarctica excursion, he's planning for a May 9 launch either in New Mexico "or the middle of the ocean if the government tries to stop me..." He hopes to reach the Kármán line, some 62.8 miles above Earth where space begins. "That way, we'll see what shape this rock really is," he said.

"More people will watch this than those who watched the fake moon landing. It will be an incredible, incredible event. People will see what I'm seeing for three hours up there and back and they'll be able to make up their own minds.... I'm the only guy capable of actually proving what shape this rock is, and that's by going up into space to do it."
The Science Channel is now filming Hughes' progress. (Here's a slick trailer for an upcoming documentary called "Rocketman".)

And Hughes says he's also claimed the legal entities that famous people are operating under, including Elon Musk, Mark Zuckerberg, and Warren Buffett, putting these powerful people in a precarious position because now "they can't even exist..."

"I have a lot of court cases going on."

"While lawmakers debate what to do about the roboscourge, engineers have cooked up some clever ways to make bots work for us, not against us," writes the Washington Post, taking a look at apps like the $4-per-month RoboKiller -- which offers malicious "answer bots": They're voicemail messages that try to keep robots and human telemarketers on the line, listening to nonsense. Answer bot options range from Trump impersonators and extended coughing sessions to someone doing vocal exercises. Even better, RoboKiller will send you an often-hilarious recording of the interaction. (It only uses these recordings when it's very sure it's a spam call.)

Another service, called Jolly Roger, doesn't sell itself as a robocall blocker but takes this auto-generated annoyance idea a step further by actively trying to game the spammers' systems, such as when to press 1 to speak to a human. It calls this tech "artificial stupidity." It costs $11.88 per year.

It's possible you're better off not engaging with a robocall in the hopes the dialer with decide the line is dead. And it's also not clear how much these actually cost the people placing robocalls. But any time robocallers spend with your bot might be minutes they're not calling someone else, so you can think of it as community service.
I'm also not sure this does any good -- but the Post's article also includes a run-down of other robocall-blocking services available from both wireless carriers and independent companies. It recommends starting with the free YouMail app, which collates data from 10 million registered users to determine which calls to block -- and in addition, "tries to trick known robocallers into taking you off their lists by playing them the beep-beep-beep sound of a dead line."

If you live in America, you can also add your phone number to the Federal government's official "Do not call" registry. "It won't help much," writes the Post, "but it only takes 30 seconds so why not?"

An anonymous reader quotes the Washington Post: Griffin Spikoski spends as much as 18 hours a day glued to his computer screen playing the wildly popular, multiplayer video game "Fortnite." His YouTube channel -- where he regularly uploads videos of himself playing the online game -- has nearly 1.2 million subscribers and more than 71 million views; figures that have netted him advertisers, sponsorships and a steady stream of income. Last year, that income totaled nearly $200,000... "It's kind of like my job," Griffin told ABC affiliate WABC-TV, noting he plays about eight hours a day in his Long Island home...

His big break came last year when Spikoski beat a well-known Fortnite player and uploaded a video of the battle to YouTube, quickly resulting in 7.5 million views, according to WABC-TV. It didn't take long, the station reported, for the teenager to make his first $100 from Twitch. Not long after, his father, Chris said, everything changed. "Two months went by and we were like, 'Alright, we're going to need to get an accountant and get a financial adviser,'" he said.

Spikoski's parents told filmmakers that they decided to remove their son from high school as his dedication to gaming deepened... Spikoski's parents said their son had been pushing them to allow him to pursue online schooling. With his success growing, they eventually relented. "It's been his dream to be a gamer, to be in e-sports, just to be in this field since he was a kid," Spikoski said, noting that his son began playing video games at age three. "We don't really see that you need a 9-to-5 job to get by in life and you can actually have fun with a career and enjoy your love and do what you love and make a living out of it," he added.

Yesterday Billboard magazine reported that Elon Musk had dropped a rap song on SoundCloud -- an auto-tuned song called "RIP Harambe." Posted under the handle Emo G Records, the two-minute track pays tribute to the Cincinnati Zoo gorilla who was killed in 2016 after a 3-year-old climbed into its living area. It's unclear if Musk stumbled upon the track, which has his name on it, or if he released the track himself...

"RIP Harambe" had more than 200,000 plays as of Sunday afternoon.
Some Twitter users left bemused replies, like "Dude, sober up by Thursday's contempt hearing." But the song appears to be part of a longer series of tweets. An anonymous reader writes: On Friday Musk had shared a blank tweet containing nothing but an emoji of a duck with his 25.5 million followers. It drew over 24,000 re-tweets, and 4,300 comments -- far more than the Harambe song (which drew only 14,000 retweets and 1,600 comments.) "Duck emoji FTW," Musk tweeted triumphantly on Sunday, following up on his earlier observation that "Duck emoji defeats Emo G Records. Crushing victory."
In its comments there was also a joke about X.com (the original online banking site Musk launched in 1999, which was eventually merged into PayPal). In 2017 Musk repurchased the domain because "it has great sentimental value" -- but replaced it with an entirely blank page with one lowercase x. In response to the duck emoji, someone tweeted that next Musk needed to update X.com.

Musk promptly replied by tweeting the URL x.com/x -- which (due to the site's error-handling) pulls up a web page with a single lowercase y.

"DEVUAN.ORG HAS BEEN PWNED" reads a new message at the home page for Devuan (a fork of Debian without systemd) -- which re-redirects to a new page named pwned.html, reports Slashdot reader DevNull127: In all capital letters, its carefully-indented message (complete with an ascii-art logo) now informs visitors that "the web sucks -- JavaScript sucks -- browsers suck." Posting the URLs to several gopher sites, it adds that "Gopher is the way -- gopher is the future."

"Kiss port 80 goodbye. Join the revolution on port 70."
The attackers identify themselves as "Green Hat Hackers," a term generally understood to mean ambitious newbie hackers who want to improve their skills. "Stop the madness," continues their message, which appeared just hours before the first day of April.

"Get yourself a gopher client."

"The Tinder dating app will soon be asking men to submit photos in order to verify their height," writes long-time Slashdot reader SonicSpike, sharing a post made Friday (March 29th) on the official Tinder blog. Let's be real, when it comes to online dating -- honesty is the best policy. Yes, your height matters as long as every other shallow aspect of physical attraction does. Please try not to take it to heart...

Height-lying ends here. To require everyone under 6' to own up to their real height, we're bringing truthfulness back into the world of online dating. Introducing Tinder's Height Verification Badge (HVB), because yes -- sometimes it matters. It's the tool we've had in our back-pockets for years, but we were hoping your honesty would allow us to keep it there... Simply input your true, accurate height with a screenshot of you standing next to any commercial building. We'll do some state-of-the-art verifying and you'll receive your badge directly on your profile.

Oh, and by the way? Only 14.5% of the U.S. male population is actually 6' and beyond. So, we're expecting to see a huge decline in the 80% of males on Tinder who are claiming that they are well over 6 feet.
The post concludes that "Tinder's HVB is coming soon to a phone near you," and Tinder's official Twitter account described the feature as "the thing you never asked for, but definitely always wanted," with a short video showing their app displaying errors for incorrect heights. (The second error message reads "Seriously... Please enter your correct height.") The video has been viewed 2.78 million times. Its tagline? "Let's bring honesty back to dating."

"It's unknown at this point if this is a real feature that the company is adding to its dating app," reported one local news site, "or an early April Fool's joke."

Slashdot reader RockDoctor writes: The project to actually construct Babbage's Analytical Engine, the first design for a general purpose computing machine, continues with the documentation phase of the programme. Since Babbage continued to refine his design almost until the day of his death, working out what he actually wanted to build is quite a task. The last year's work is reported to includes work on a batch of previously unknown and uncatalogued materials discovered since the project's inception in 2011.

These decades, people don't think much of producing a new programming language to suit particular tasks — to "scratch an itch" in the vernacular. As with so many things, Babbage was a pioneer, according to the Plan 28 blog: :

There have already been significant finds. The Notations for Difference Engine 1, dating from 1834, thought to exist, had never come to light. These have now been found and represent a crucial piece in the puzzle of the developmental trajectory of the symbolic language Babbage developed as a design aid, to describe and specify his engine, and used extensively in the development of the Analytical Engine.

RockDoctor adds, "Anyone who has been tasked with taking over a project from someone else (retired, sacked, beheaded, whatever) will recognise this feeling..."

The survey so far has identified mis-titled drawings, single drawings that have two unrelated catalogue entries, and drawings known to exist from earlier scholarly work but not located.

"The hope of the project is to have a working machine in time for Babbages sesquicentenary in 2021."

IEEE Spectrum is publishing a six-part series exploring the human history of AI. the_newsbeagle writes: The 19th century British engineer Charles Babbage is sometimes called the father of the computer. But his first design for a massive computing machine, a contraption called the Difference Engine that had some 25,000 parts, was just a giant calculator intended to handle logarithmic tables. It wasn't until he began designing his first Analytical Engine that he began to dream of a smart machine that could handle more general-purpose computations.

This short essay argues that Babbage's creative leap was inspired by an early example of AI hype: A supposed chess-playing machine called The Turk that had astounded onlookers throughout the courts of Europe. Babbage played two games against the Turk, and lost both.

"Baseball's potential future will be showcased in the independent Atlantic League this year, and it includes robot umpires..." reports ESPN, calling it part of "a wide variety of experiments that the Atlantic League will run this season as part of its new partnership with Major League Baseball." While MLB has long tested potential rule changes in the minor leagues, its three-year partnership with the Atlantic League -- an eight-team league that features former major leaguers trying to return to affiliated ball -- offers the ability to try more radical rules. MLB has chafed at using technology to replace ball-and-strike-calling duties for umpires, fearful that it's not yet consistent enough to warrant implementation... [W]ith the TrackMan system installed at Atlantic League stadiums, MLB will have a trove of data to analyze and see the effect of doing so.
Other changes aim to speed up the game, including bans on visits to the pitcher's mound and shortening the amount of time between innings.

An anonymous reader quotes Business Insider's update on Microsoft Clippy, the animated cartoon paperclip that was Office's virtual assistant until the early 2000s, that "everyone loved to hate."

After 18 years, has it become retro chic? When Chloe Condon, a newly hired Microsoft cloud evangelist, ordered new business cards, she avoided the standard corporate look and instead went with Clippy-themed cards and tweeted them out... They've got a picture of Clippy on the front and on the back they say, "It looks like you are trying to get in touch with Chloe," with her contact info listed below...

Naturally, the Clippy The Paperclip Twitter account loved these cards. He tweeted, "@chloecondon It looks like you're using my likeness on your new business cards. Would you like help with WAIT I'M ON BUSINESS CARDS NOW?!" And then former Microsoft exec Steven Sinofsky, the man credited for developing Microsoft Office into a massive hit, noticed the cards and tweeted, "I suppose if you live long enough, others will wear your failures as a badge of honor...."

After four years of scorn, Clippy was officially retired in 2001. Sinofsky tells Business Insider that the company even issued a funny press release about it.... Microsoft even held an official retirement party for him in San Francisco, too. Sinfosky shared a photo from that party with us... If you look closely, you'll see unemployed Clippy is actually using the party thrown in his honor to collect charity for himself and beg for food.

A burn surgeon at Loyola University Medical has treated eight different people for second and third-degree burns after they attempted to replicate the viral "boiling water challenge," according to one local news station. These people (like many others as seen across social media) heated water and threw it into the sub-zero air, expecting it to transform into a powder-like state and blow away in the wind. But that apparently didn't work out for everyone; sometimes the water stayed liquid and hit people. The youngest patient seen at Loyola is 3 years old. Sanford said that individual (like some of the other patients) was just standing next to someone else throwing the water.... Sanford said there are likely several others out there with first degree burns that didn't seek medical attention.
CNN Wire Services also reports at least three more "boiling water challenge" burn victims in Minneapolis and Iowa.

"What's the worst that can happen?" thought Nicko Feinberg last December when he listed his house on Airbnb. The listing explicitly said no parties. Then a request came through to book the house for one night on New Year's Day. It was from a young man, probably in his early 20s. He had one review but it was terrific.... I picked up my boys and we stayed down the road at my mother's apartment... When I got back [the next day] I saw three or four cars in the driveway. I threw my food down and knew I was screwed. Inside there were about 12 young adults, all trying to clean.

The floors looked like someone had poured Jagermeister and champagne everywhere and then danced on them. Everything seemed wrong: my artwork was not on the walls; there was furniture missing; the glass panel on my staircase was shattered; even the floor didn't seem level any more. Then I noticed they were using my best sheets and towels as mops....I told them no one was leaving and I called the police and Airbnb. When a police officer turned up, he said it was a civil matter, before adding: "We were here last night...."

Ultimately, it was just stuff and I knew it would be OK. But I felt a massive disappointment in humanity. That night, it wasn't hard for me and my boys to find Instagram pictures and videos of the party. It was horrifying to see so many people in the house, jumping up and down on the furniture and windowsills. They broke my hot tub and tiles in the bathroom; when I looked in the rubbish bags, I saw all my drinks bottles empty, as well as broken glasses and towels. I found an image online of the invite that said, "Mansion Party" with my address. There had been 300 people there. Boys were charged to enter; girls got in free.
While he won't disclose what Airbnb paid him for the damage, "a year later repairs are continuing. The floor is still uneven." But he told one local news channel that the damage was over $100,000, adding "There's footprints on my bathroom walls."

At one point more than 100 cars had been parked outside, according to a police report, and the 23-year-old was ultimately charged with "disorderly conduct". He also was banned permanently from Airbnb -- which said in a statement that "negative incidents are incredibly rare."
