Popular Science Is Now a Fully Digital Magazine (popsci.com) 20

kackle writes: I just received an email telling me that "Popular Science" magazine is no more. That is, it is to be delivered to readers from now on only via ones and zeros. I can't say I had a subscription since its beginnings in 1872, but I did learn much from the rag and will sincerely miss it. "Today, we're unveiling our biggest change in my tenure: Popular Science is now a fully digital magazine," writes Editor-in-Chief Corinne Iozzio. In addition to "redesigned" and "reimagined stories" made especially for mobile devices, Iozzio notes that their various apps "include an archive of 15-plus years of back issues..."

"The mediums may change, but even after all these evolutions and iterations, our core belief remains as fixed and focused as it was in 1872: Embracing science and tech means living in the realm of possibility."

Software Program Dr.Fill Finally Wins Prestigious Crossword Puzzle Event 32

Long-time Slashdot reader gregstumph writes: Dr.Fill, a software program that solves crossword puzzles, finished in first place at the 2021 American Crossword Puzzle Tournament, for the first time ever (its previous best was 11th place in 2017). Dr.Fill, created by Matt Ginsberg, has been participating as a non-competitor at the tournament since 2012. This year, Ginsberg made improvements to Dr.Fill with the assistance of a team from the Berkeley NLP Group.
The program finished "a scant 15 points ahead of Erik Agard on the main block of puzzles 1-7," Ginsberg posted on Facebook. This was followed by "then solving the playoff puzzle perfectly in 49 seconds" (while according to Wikipedia the fastest human competitor, Tyler Hinman, took three minutes to solve the puzzle).

The Facebook post adds graciously, "Total kudos to Erik, the true winner of puzzles 1-7, and to Tyler Hinman, the winner of the event itself."

Is SpaceX's Starlink Becoming the World's Dominant ISP? (cringely.com) 162

Technology/space pundit Robert Cringely writes that SpaceX's winning bid on NASA's Artemis lunar lander contract was helped by its flexibility in how it would be paid — made possibly by SpaceX's cushy financial position.

But he believes that's part of a larger story about SpaceX's "steadily crushing its competitors by building a hyper-efficient space ecosystem where the other guys are just building rockets," arguing that SpaceX has already won the global war of ISPs "at a net cost of ZERO dollars," if not a negative net cost, while realizing a dream of a satellite internet service that for 30 years has eluded investors like Bill Gates:

SpaceX making a profit where one would not normally exist comes thanks to U.S. residents who pay telephone and Internet bills. The U.S. Federal Communications Commission (FCC) has been socking-away for a decade about $1.8 billion per year from you and me, saving-up to pay for expansions of rural telephony and broadband. There is now about $16 billion in this federal kitty and the FCC is starting to spend it with telephone and internet service providers, paying them to extend broadband and voice services to remote rural users who are presently underserved or unserved completely. All of this is both perfectly legal and even a good idea. Everybody wins. But circumstances are turning out to indicate that SpaceX is probably winning more than anyone else... So far SpaceX has won auctions for service in parts of 35 states for a total of $885 million... SpaceX just bid for potential customers in places where other companies typically didn't even bother to bid. They took the obvious remote customers and apparently won't be over-charging them or the government, either...

There is no FCC rule saying Comcast couldn't sub-contract...difficult customers to Starlink... Instead of earning $885 million of those FCC subsidies, Starlink is more likely to gain half of the full $9.2 billion — money that can be used for any purpose including financing that Artemis lander. But remember that satellites are a global resource. If SpaceX launches 4000 or 12,000 Starlink satellites to serve the USA, they'll also serve anywhere else the satellites overfly, even North Korea. The same level of service Starlink offers in Omaha will be available in Vietnam or on tankers in the Pacific ocean.

Once Starlink becomes effectively the dominant ISP in America, it will also become the dominant ISP in the world. And all at no cost to SpaceX since the expansion will have been financed from our phone bills.

Cringely cites estimates that 40,000 satellites would be enough to serve every Internet user on Earth, as well as IoT devices and even future as-yet-uninvented network services.

He also asks whether this might ultimately make it harder for China to censor the internet — and whether Apple might attempt a competing satellite-to-phone network, possibly using technology from Samsung.

Security Researcher Dan Kaminsky Has Died 56

Security researcher Marc Rogers (also a BBC contributor) tweeted this morning "I guess theres no hiding it now. We lost Dan Kaminsky yesterday. One of the brightest lights in infosec and probably the kindest soul I knew. The vacuum he leaves behind is impossible to measure. Please keep speculation to yourself and be respectful of his family and friends."

In later tweets, Rogers says he was proud that Kaminsky was his friend, adding "I could literally wrote a book of Dan Kaminsky tales. From shenanigans at events all over the world, to parties and just crazy stuff that happened at the spur of a moment. But most about his crazy brilliant kind generous ideas and offers of help and support. He was one of a kind."

Even the stories in Kaminsky's Wikipedia entry are impressive: He is known among computer security experts for his work on DNS cache poisoning, and for showing that the Sony Rootkit had infected at least 568,200 computers and for his talks at the Black Hat Briefings.

In June 2010, Kaminsky released Interpolique, a beta framework for addressing injection attacks such as SQL injection and cross-site scripting in a manner comfortable to developers.

On June 16, 2010, he was named by ICANN as one of the Trusted Community Representatives for the DNSSEC root.

"Dan was a force of nature," adds Marc Rogers on Twitter. "A hacker who saw not just 1 or 2 moves ahead but so many you sometimes wondered if he was playing the same game: I asked him for a demo. He brought a record turntable he used to move a VM forwards & backwards in time like a DJ scratching."

Founder of Adobe Dies at Age 81 (gizmodo.com) 98

Long-time Slashdot reader sandbagger brings the news that Charles 'Chuck' Geschke, the co-founder of Adobe, had died at the age of 81.

The company started in co-founder John Warnock's garage in 1982, and was named after the Adobe Creek which ran behind Warnock's home, offering pioneering capabilities in "What you see is what you get" (or WYSIWYG) desktop publishing.

Gizmodo reports: "This is a huge loss for the entire Adobe community and the technology industry, for whom he has been a guide and hero for decades," Adobe CEO Shantanu Narayen wrote in an email to staff.

"As co-founders of Adobe, Chuck and John Warnock developed groundbreaking software that has revolutionized how people create and communicate, " he continued. "Chuck instilled a relentless drive for innovation in the company, resulting in some of the most transformative software inventions, including the ubiquitous PDF, Acrobat, Illustrator, Premiere Pro and Photoshop."

After earning a doctorate from Carnegie Mellon University, Geschke met Warnock while working at the Xerox Palo Alto Research Center, according to the Mercury News. The two left the company in 1982 and founded Adobe to develop software. Their first product was Adobe PostScript, which Narayen lauded as "an innovative technology that provided a radical new way to print text and images on paper and sparked the desktop publishing revolution."

Debian Votes to Issue No Statement on Stallman's Return to the FSF Board (debian.org) 209

An anonymous reader writes: Debian Project Secretary Kurt Roeckx has announced the results of a closely-watched vote on what statement would be made about Richard Stallman's readmission to the Free Software Foundation's board.
Seven options were considered, with the Debian project's 420 voting developers also asked to rank their preferred outcomes:
  • Option 1: "Call for the FSF board removal, as in rms-open-letter.github.io"
  • Option 2: "Call for Stallman's resignation from all FSF bodies"
  • Option 3: "Discourage collaboration with the FSF while Stallman is in a leading position"
  • Option 4: "Call on the FSF to further its governance processes"
  • Option 5: "Support Stallman's reinstatement, as in rms-support-letter.github.io"
  • Option 6: "Denounce the witch-hunt against RMS and the FSF"
  • Option 7: "Debian will not issue a public statement on this issue"

While all seven options achieved a quorum of votes, two failed to achieve a majority — options 5 and 6. ("Support Stallman's reinstatement" and "Denounce the witch-hunt...") The option receiving the most votes was #7 (not issuing a public statement) — but it wasn't that simple. The vote's final outcome was determined by comparing every possible pair of options to determine which option would still be preferred by a majority of voters in each possible comparision.

In this case, that winner was still the option which had also received the most votes:


Debian will not issue a public statement on this issue.
The Debian Project will not issue a public statement on whether Richard Stallman should be removed from leadership positions or not.

Any individual (including Debian members) wishing to (co-)sign any of the open letters on this subject is invited to do this in a personal capacity.



The results are captured in an elaborate graph. Numbers inside the ovals show the final ratio of yes to no votes (so a number higher than 1.00 indicates a majority, with much higher numbers indicating much larger majorities). Numbers outside the ovals (along the lines) indicate the number of voters who'd preferred the winning choice over the losing choice (toward which the arrow is pointing).

The winning option is highlighted in blue.

Human Taste Buds Can Tell the Difference Between Normal and 'Heavy' Water, Study Finds (sciencealert.com) 104

An anonymous reader quotes a report from ScienceAlert: [T]here's been a longstanding question over whether heavy water tastes the same as regular drinking water -- or whether its subtle isotopic variation yields a different taste that people may be able to perceive. "There is anecdotal evidence from the 1930s that the taste of pure D2O is distinct from the neutral one of pure H2O, being described mostly as 'sweet,'" an international team of researchers led by first authors and biochemists Natalie Ben Abu and Philip E. Mason explains in a new study. [I]n their new research, Ben Abu, Mason, and their team can finally confirm that there really is something a bit different about the taste of heavy water. "Despite the fact that the two isotopes are nominally chemically identical, we have shown conclusively that humans can distinguish by taste (which is based on chemical sensing) between H2O and D2O, with the latter having a distinct sweet taste," explains senior author and physical chemist Pavel Jungwirth from the Czech Academy of Sciences.

In a taste-testing experiment with 28 participants, most people were able to distinguish between H2O and D2O, and tests with mixed amounts of the waters revealed that greater proportions of heavy water were perceived as tasting sweeter. In tests with mice, however, the animals did not seem to prefer drinking heavy water over regular water, although they did show a preference for sugared water -- suggesting that in mice, D2O does not elicit the same sweet taste that people can perceive. Other taste tests conducted by the team suggest why this is so, indicating that human taste receptivity to D2O is mediated by the taste receptor TAS1R2/TAS1R3, which is known to respond to sweetness in both natural sugars and artificial sweeteners. Experiments in the lab with HEK 293 cells confirmed the same thing, showing robust responses in TAS1R2/TAS1R3 expressing cells when exposed to D2O.
The findings are published in the journal Communications Biology.

'Why We're Freaking Out About Substack' (nytimes.com) 113

The New York Times explores whether Substack is just a company that makes it easy to charge for newsletters — or a new direct-to-consumer media that's part of a larger cultural shift? This new ability of individuals to make a living directly from their audiences isn't just transforming journalism. It's also been the case for adult performers on OnlyFans, musicians on Patreon, B-list celebrities on Cameo. In Hollywood, too, power has migrated toward talent, whether it's marquee showrunners or actors. This power shift is a major headache for big institutions, from The New York Times to record labels. And Silicon Valley investors, eager to disrupt and angry at their portrayal in big media, have been gleefully backing it. Substack embodies this cultural shift, but it's riding the wave, not creating it...

A New York Times opinion writer, Charlie Warzel, is departing to start a publication on Substack called Galaxy Brain... The Times wouldn't comment on his move, but is among the media companies trying to develop its own answer to Substack and recently brought the columnist Paul Krugman's free Substack newsletter to the Times platform... [T]he biggest threat to Substack is unlikely to be the Twitter-centric political battles among some of its writers. The real threat is competing platforms with a different model. The most technically powerful of those is probably Ghost, which allows writers to send and charge for newsletters, with monthly fees starting at $9. While Substack is backed by the venture capital firm Andreessen Horowitz, Ghost has Wikipedia vibes: It is open-source software developed by a nonprofit...

And it's easy to leave. Unlike on Facebook or Twitter, Substack writers can simply take their email lists and direct connections to their readers with them. Substack's model of taking 10 percent of its writers' subscriptions is "too greedy of a slice to take of anyone's business with very little in return," said Ghost's founder and chief executive, John O'Nolan, a tattooed, nomadic Irishman who is bivouacked in Hollywood, Fla. He said he believed subscription newsletter publishing was "destined to be commoditized."

But Ghost represents an even purer departure from legacy media. More than half of the sites on the platform simply run the software off their own servers. "The technology is designed to be decentralized, and there's no one institution or one corporation that can decide what is OK," he said.

The article also notes that Twitter recently bought the newsletter platform Revue, while Facebook "is developing ambitious plans for a rival that will provide a platform for local journalists, among other writers."

And in a section on indie spirit, it adds as an aside that Bustle Digital Group "confirmed to me that it's reviving the legendary blog Gawker under a former Gawker writer, Leah Finnegan."

Would You Tell an Angel Investor How to Start a New Country? (1729.com) 59

Angel investor Balaji S. Srinivasan (also the former CTO of Coinbase) is now focused on 1729.com, which wants to give you money to do his bidding — or something like that. He's calling it "the first newsletter that pays you.

"It has a regular feed of paid tasks and tutorials with $1000+ in crypto prizes per day, and doubles as a vehicle for distributing a new book I've been writing called The Network State."

His latest post? "How to Start a New Country" (which envisions starting with a "cloud first" digital community): We recruit online for a group of people interested in founding a new virtual social network, a new city, and eventually a new country. We build the embryonic state as an open source project, we organize our internal economy around remote work, we cultivate in-person levels of civility, we simulate architecture in VR, and we create art and literature that reflects our values.

Over time we eventually crowdfund territory in the real world, but not necessarily contiguous territory. Because an under-appreciated fact is that the internet allows us to network enclaves. Put another way, a cloud community need not acquire all its territory in one place at one time. It can connect a thousand apartments, a hundred houses, and a dozen cul-de-sacs in different cities into a new kind of fractal polity with its capital in the cloud. Over time, community members migrate between these enclaves and crowdfund territory nearby, with every individual dwelling and group house presenting an independent opportunity for expansion...

[Cloud countries] are set up to be a scaled live action role-playing game (LARP), a feat of imagination practiced by large numbers of people at the same time. And the experience of cryptocurrencies over the last decade shows us just how powerful such a shared LARP can be...

The cloud country concept "just" requires stacking together many existing technologies, rather than inventing new ones like Mars-capable rockets or permanent-habitation seasteads. Yet at the same time it avoids the obvious pathways of election, revolution, and war — all of which are ugly and none of which provide much venue for individual initiative...

Could a sufficiently robust cloud country with, say, 1-10M committed digital citizens, provable cryptocurrency reserves, and physical holdings all over the earth similarly achieve societal recognition from the United Nations?

For the "do his bidding" part, the post promises that up to ten $100 prizes will be awarded to people who share constructive reviews on their sites/social media pages (including proposals for extensions).

Previously the site had offered $100 for the ten best hirelings "running a newsletter for technological progressives at your own domain, as a way to begin incentivizing the decentralization of media." (It cited a tweet that argues succinctly that "The NYT is telling anti-longevity stories for us. We must take control of our own story.") In general the site describes itself as "a newsletter for technological progressives. That means people who are into cryptocurrencies, startup cities, mathematics, transhumanism, space travel, reversing aging, and initially-crazy-seeming-but-technologically-feasible ideas." So the newsletter-creating task had envisioned them all "constantly pushing for technology in general and reversing aging in particular, writing like their lives depended on it. In other words, blog or die!"

Other rewards went to the first 10 people to complete three Elixir problems, the 100 people who posted the best inspiring proof-of-exercising photos, and 40 people who helped identify people and places "where the ascending world is surpassing the declining world."

For one of his latest "tasks," Srinivasan wants you to read a long essay on quantum computing (and answer questions), with an optional series of "review emails". $10 in bitcoin will be awarded only to the first and last 50 readers/question-answerers, while another $100 in bitcoin will be awarded to the first and last 5 review-email readers who "persist for a month."

Critical Zoom Vulnerability Triggers Remote Code Execution Without User Input (zdnet.com) 14

An anonymous reader quotes a report from ZDNet: A zero-day vulnerability in Zoom which can be used to launch remote code execution (RCE) attacks has been disclosed by researchers. The researchers from Computest demonstrated a three-bug attack chain that caused an RCE on a target machine, and all without any form of user interaction. As Zoom has not yet had time to patch the critical security issue, the specific technical details of the vulnerability are being kept under wraps. However, an animation of the attack in action demonstrates how an attacker was able to open the calculator program of a machine running Zoom following its exploit. As noted by Malwarebytes, the attack works on both Windows and Mac versions of Zoom, but it has not -- yet -- been tested on iOS or Android. The browser version of the videoconferencing software is not impacted. Computest researchers Daan Keuper and Thijs Alkemade earned themselves $200,000 for this Zoom discovery, as it was part of the Pwn2Own contest.

In a statement to Tom's Guide, Zoom thanked the Computest researchers and said the company was "working to mitigate this issue with respect to Zoom Chat." In-session Zoom Meetings and Zoom Video Webinars are not affected. "The attack must also originate from an accepted external contact or be a part of the target's same organizational account," Zoom added. "As a best practice, Zoom recommends that all users only accept contact requests from individuals they know and trust."

Wix and Their Dirty Tricks (ma.tt) 60

Matt Mullenweg, co-founder of the open-source blogging platform WordPress, writes: Wix, the website builder company you may remember from stealing WordPress code and lying about it, has now decided the best way to gain relevance is attacking the open source WordPress community in a bizarre set of ads. They can't even come up with original concepts for attack ads, and have tried to rip-off of Apple's Mac vs PC ads, but tastelessly personify the WordPress community as an absent, drunken father in a therapy session.

I have a lot of empathy for whoever was forced to work on these ads, including the actors, it must have felt bad working on something that's like Encyclopedia Britannica attacking Wikipedia. WordPress is a global movement of hundreds of thousands of volunteers and community members, coming together to make the web a better place. The code, and everything you put into it, belongs to you, and its open source license ensures that you're in complete control, now and forever. WordPress is free, and also gives you freedom. So if we're comparing website builders to abusive relationships, Wix is one that locks you in the basement and doesn't let you leave. I'm surprised consumer protection agencies haven't gone after them.

Wix is a for-profit company with a valuation that peaked at around 20 billion dollars, and whose business model is getting customers to pay more and more every year and making it difficult to leave or get a refund. (Don't take my word for it, look at their investor presentations.) They are so insecure that they are also the only website creator I'm aware of that doesn't allow you to export your content, so they're like a roach motel where you can check in but never check out. Once you buy into their proprietary stack you're locked in, which even their support documentation admits.

Why IBM is Pushing 'Fully Homomorphic Encryption' (venturebeat.com) 122

VentureBeat reports on a "next-generation security" technique that allows data to remain encrypted while it's being processed.

"A security process known as fully homomorphic encryption is now on the verge of making its way out of the labs and into the hands of early adopters after a long gestation period." Companies such as Microsoft and Intel have been big proponents of homomorphic encryption. Last December, IBM made a splash when it released its first homomorphic encryption services. That package included educational material, support, and prototyping environments for companies that want to experiment. In a recent media presentation on the future of cryptography, IBM director of strategy and emerging technology Eric Maass explained why the company is so bullish on "fully homomorphic encryption" (FHE)...

"IBM has been working on FHE for more than a decade, and we're finally reaching an apex where we believe this is ready for clients to begin adopting in a more widespread manner," Maass said. "And that becomes the next challenge: widespread adoption. There are currently very few organizations here that have the skills and expertise to use FHE." To accelerate that development, IBM Research has released open source toolkits, while IBM Security launched its first commercial FHE service in December...

Maass said in the near term, IBM envisions FHE being attractive to highly regulated industries, such as financial services and health care. "They have both the need to unlock the value of that data, but also face extreme pressures to secure and preserve the privacy of the data that they're computing upon," he said.

The Wikipedia entry for homomorphic encryption calls it "an extension of either symmetric-key or public-key cryptography."

Ask Slashdot: Is a Software RAID Better Than a Hardware RAID? (wikipedia.org) 359

RockDoctor (Slashdot reader #15,477) wants to build a personal network-attached storage solution, maybe using a multiple-disk array (e.g., a RAID). But unfortunately, "My hardware pool is very shallow." I eBay'd a desktop chassis, whose motherboard claims (I discovered, on arrival) RAID capabilities. There, I have a significant choice — to use the on-board RAID, or do it entirely in software (e.g. OpenMediaVault)?

I'm domestic — a handful of terabytes — but I expect the answer to change as one goes through the petabytes into the exabytes. What do the dotters of the slash think?

Privacy Advocate Confronts ACLU Over Its Use of Google and Facebook's Targeted Advertising (twitter.com) 20

Ashkan Soltani was the Chief Technologist of America's Federal Trade Commission in 2014 — and earlier was a staff technologist in its Division of Privacy and Identity Protection helping investigate tech companies including Google and Facebook

Friday on Twitter he accused another group of privacy violations: the nonprofit rights organization, the American Civil Liberties Union. Yesterday, the ACLU updated their privacy statement to finally disclose that they share constituent information with 'service providers' like Facebook for targeted advertising, flying in the face of the org's public advocacy and statements.

In fact, I was retained by the ACLU last summer to perform a privacy audit after concerns were raised internally regarding their data sharing practices. I only agreed to do this work on the promisee by ACLU's Executive Director that the findings would be made public. Unfortunately, after reviewing my findings, the ACLU decided against publishing my report and instead sat on it for ~6 months before quietly updating their terms of service and privacy policy without explanation for the context or motivations for doing so. While I'm bound by a nondisclosure agreement to not disclose the information I uncovered or my specific findings, I can say with confidence that the ACLU's updated privacy statements do not reflect the full picture of their practices.

For example, public transparency data from Google shows that the ACLU has paid Google nearly half a million dollars to deliver targeted advertisements since 2018 (when the data first was made public). The ACLU also opted to only disclose its advertising relationship with Facebook only began in 2021, when in truth, the relationship spans back years totaling over $5 million in ad-spend. These relationships fly against the principles and public statements of the ACLU regarding transparency, control, and disclosure before use, even as the organization claims to be a strong advocate for privacy rights at the federal and state level. In fact, the NY Attorney General conducted an inquiry into whether the ACLU had violated its promises to protect the privacy of donors and members in 2004. The results of which many aren't aware of. And to be clear, the practices described would very much constitute a 'sale' of members' PII under the California Privacy Rights Act (CPRA).

The irony is not lost on me that the ACLU vehemently opposed the CPRA — the toughest state privacy law in the country — when it was proposed. While I have tremendous respect for the work the ACLU and other NGOs do, it's important that nonprofits are bound by the same privacy standards they espouse for everyone else. (Full disclosure: I'm on the EFF advisory board and was recently invited to join EPIC's board.)

My experience with the ACLU further amplifies the need to have strong legal privacy protections that apply to nonprofits as well as businesses — partially since many of the underlying practices, particularly in the area of fundraising and advocacy, are similar if not worse.

Soltani also re-tweeted an interesting response from Alex Fowler, a former EFF VP who was also Mozilla's chief privacy officer for three years: I'm reminded of EFF co-founder John Gilmore telling me about the Coders' Code: If you find a bug or vulnerability, tell the coder. If coder ignores you or refuses to fix the issue, tell the users.

Isamu Akasaki, Inventor of First Efficient Blue LED, Dies At 92 (japantimes.co.jp) 22

Physicist Isamu Akasaki, a co-winner of the 2014 Nobel Prize in physics for inventing the world's first efficient blue light-emitting diodes, has died, Meijo University said Friday. He was 92. The Japan Times reports: Akasaki, born in Kagoshima Prefecture, graduated from Kyoto University in 1952 before working at Matsushita Electric Industrial Co., now Panasonic Corp. He started working at Nagoya University as a professor in 1981 and was later given an honorary title. In 2014, he shared the Nobel Prize with physicist Hiroshi Amano, professor at the university, and Japan-born American Shuji Nakamura, professor at the University of California, Santa Barbara.

Akasaki, when he was a professor at Nagoya University, worked with Amano to produce gallium nitride crystals, and succeeded in 1989 in creating the world's first blue LED. Akasaki was honored in 1997 by the Japanese government with the Medal with Purple Ribbon, an honor bestowed on those who have made contributions to academic and artistic developments.

Scientists Just Killed the EmDrive (popularmechanics.com) 137

In major international tests, the physics-defying EmDrive has failed to produce the amount of thrust proponents were expecting. In fact, in one test at Germany's Dresden University, it didn't produce any thrust at all. Is this the end of the line for EmDrive? Popular Mechanics: The crux of the EmDrive is if you bounce microwaves around inside the tube, they exert more force in one direction than the other, creating a net thrust without the need for any propellant. And when NASA and a team at Xi'an in China tried this, they actually got a small-but-distinct net force. Now, however, physicists at the Dresden University of Technology (TU Dresden) are saying those promising results showing thrust were all false positives that are explained by outside forces. The scientists recently presented their findings in three papers at Space Propulsion Conference 2020 +1, with titles like "High-Accuracy Thrust Measurements of the EmDrive and Elimination of False-Positive Effects." (Other two studies here and here)

Using a new measuring scale and different suspension points of the same engine, the TU Dresden scientists "were able to reproduce apparent thrust forces similar to those measured by the NASA team, but also to make them disappear by means of a point suspension," researcher Martin Tajmar told the German site GreWi. The verdict: "When power flows into the EmDrive, the engine warms up. This also causes the fastening elements on the scale to warp, causing the scale to move to a new zero point. We were able to prevent that in an improved structure. Our measurements refute all EmDrive claims by at least 3 orders of magnitude."

UNIX's Founders Created Another OS at Bell Labs: 'Plan 9' (bell-labs.com) 135

The team behind UNIX also built another operating system at Bell Labs, writes the corporate CTO and president of Nokia Bell Labs: Starting in the late 1980s, a group led by Rob Pike and UNIX co-creators Ken Thompson and Dennis Ritchie developed "Plan 9". Their motivation was two-fold: to build an operating system that would fit an increasingly distributed world, and to do so in a clean and elegant manner. The plan was not to build directly on the Unix foundation but to implement a new design from scratch. The result was named Plan 9 from Bell Labs — the name an inside joke inspired by the cult B-movie "Plan 9 from Outer Space."

Plan 9 is built around a radically different model from that of conventional operating systems. The OS is structured as a collection of loosely coupled services, which may be hosted on different machines. Another key concept in its design is that of a per-process name space: services can be mapped on to local names fixed by convention, so that programs using those services need not change if the current services are replaced by others providing the same functionality.

Despite the groundbreaking innovations in Plan 9, the operating system did not take off — at least not enough to justify Bell Labs continued investment in Plan 9 development. But Plan 9's innovations found their way into many commercial OSes: the concept of making OS services available via the file system is now pervasive in Linux; Plan 9's minimalist windowing system design has been replicated many times; the UTF-8 character encoding used universally today in browsers was invented for, and first implemented in, Plan 9; and the design of Plan 9 anticipated today's microservice architectures by more than a decade...!

Starting this week, Plan 9 will have a new home in the space it helped define: cyberspace. We are transferring the copyright in Plan 9 software to the Plan 9 Foundation for all future development, allowing them to carry on the good work that Bell Labs and many other Plan 9 enthusiasts have undertaken over the past couple of decades. Indeed, there is an active community of people who have been working on Plan 9 and who are interested in the future evolution of this groundbreaking operating system. That community is organizing itself bottom-up into the new Plan 9 Foundation, which is making the OS code publicly available under a suitable open-source software license.

We at Nokia and Bell Labs are huge advocates for the power of open-source communities for such pioneering systems that have the potential to benefit the global software development community. Who knows, perhaps Plan 9 will become a part of the emerging distributed cloud infrastructure that will underpin the coming industrial revolution?

On cURL's 23rd Anniversary, Creator Daniel Stenberg Celebrated With 3D-Printed 'GitHub Steel' Contribution Graph (daniel.haxx.se) 25

This week Swedish developer Daniel Stenberg posted a remarkable reflection on the 23rd anniversary of his command-line data tool, cURL: curl was adopted in Red Hat Linux in late 1998, became a Debian package in May 1999, shipped in Mac OS X 10.1 in August 2001. Today, it is also shipped by default in Windows 10 and in iOS and Android devices. Not to mention the game consoles, Nintendo Switch, Xbox and Sony PS5.

Amusingly, libcurl is used by the two major mobile OSes but not provided as an API by them, so lots of apps, including many extremely large volume apps bundle their own libcurl build: YouTube, Skype, Instagram, Spotify, Google Photos, Netflix etc. Meaning that most smartphone users today have many separate curl installations in their phones.

Further, libcurl is used by some of the most played computer games of all times: GTA V, Fortnite, PUBG mobile, Red Dead Redemption 2 etc.

libcurl powers media players and set-top boxes such as Roku, Apple TV by maybe half a billion TVs.

curl and libcurl ships in virtually every Internet server and is the default transfer engine in PHP, which is found in almost 80% of the world's almost two billion websites.

Cars are Internet-connected now. libcurl is used in virtually every modern car these days to transfer data to and from the vehicles.

Then add media players, kitchen and medical devices, printers, smart watches and lots of "smart"; IoT things. Practically speaking, just about every Internet-connected device in existence runs curl.

I'm convinced I'm not exaggerating when I claim that curl exists in over ten billion installations world-wide...

Those 300 lines of code in late 1996 have grown to 172,000 lines in March 2021.

Stenberg attributes cURL's success to persistence. "We hold out. We endure and keep polishing. We're here for the long run. It took me two years (counting from the precursors) to reach 300 downloads. It took another ten or so until it was really widely available and used." But he adds that 22 different CPU architectures and 86 different operating systems are now known to have run curl.

In a later blog post titled "GitHub Steel," Stenberg also reveals that GitHub gave him a 3D-printed steel version of his 2020 GitHub contribution matrix — accompanied by a friendly note. "Please accept this small gift as a token of appreciation on behalf of all of us here at GitHub, and everyone who benefits from your work."

Watch AI Grow a Walking Caterpillar In Minecraft (sciencemag.org) 22

sciencehabit shares a report from Science Magazine: The video in this story will be familiar to anyone who's played the 3D world-building game Minecraft. But it's not a human constructing these castles, trees, and caterpillars -- it's artificial intelligence. The algorithm takes its cue from the "Game of Life," a so-called cellular automaton. There, squares in a grid turn black or white over a series of timesteps based on how many of their neighbors are black or white. The program mimics biological development, in which cells in an embryo behave according to cues in their local environment.

The scientists taught neural networks to grow single cubes into complex designs containing thousands of bricks, like the castle or tree or furnished apartment building above, and even into functional machines, like the caterpillar. And when they sliced a creation in half, it regenerated. (Normally in Minecraft, a user would have to reconstruct the object by hand.) Going forward, the researchers hope to train systems to grow not only predefined forms, but to invent designs that perform certain functions. This could include flying, allowing engineers to find solutions human designers would not have otherwise foreseen. Or tiny robots might use local interactions to assemble rescue robots or self-healing buildings.
The researchers presented their system in a paper posted on arXiv.

Progress Continues On Recreating the Babbage Programmable Computer (plan28.org) 12

Long-time Slashdot reader RockDoctor writes: A project to create a working example of [english mathematician and computer pioneer Charles Babbage's] original "steampunk computer," referred to by Babbage as the "Analytical Engine 30," is continuing. The update comes via a "Spring 2021 report" to the Computer Conservation Society.

The main news is that a new series of plans, dating from about 1857 have been found and are being examined for incorporation into the final design. "One remarkable feature is the extension of the Store to 1000 registers, and most intriguingly various methods of mechanically addressing the store contents," reads the update. This would compare well with electronic processor design... not that anyone is expecting this machine, when built, to be blisteringly fast.

Could a steam-powered Analytical Engine support backup DNS services in a post-apocalyptic world? Is this Cloudflare's ultimate plan?
