Bluesky Opens To the Public

An anonymous reader quotes a report from TechCrunch: After almost a year as an invite-only app, Bluesky is now open to the public. Funded by Twitter co-founder Jack Dorsey, Bluesky is one of the more promising micro-blogging platforms that could provide an alternative to Elon Musk’s X. Before opening to the public, the platform had about 3 million sign-ups. Now that anyone can join, the young platform faces a challenge: How can it meaningfully stand up to Threads’ 130 million monthly active users, or even Mastodon’s 1.8 million?

Bluesky looks and functions like Twitter at the outset, but the platform stands out because of what lies under the hood. The company began as a project inside of Twitter that sought to build a decentralized infrastructure called the AT Protocol for social networking. As a decentralized platform, Bluesky’s code is completely open source, which gives people outside of the company transparency into what is being built and how. Developers can even write their own code on top of the AT Protocol, so they can create anything from a custom algorithm to an entirely new social platform.

“What decentralization gets you is the ability to try multiple things in parallel, and so you’re not bottlenecking change on one organization,” Bluesky CEO Jay Graber told TechCrunch. “The way we built Bluesky actually lets anyone insert a change into the product.” This setup gives users more agency to control and curate their social media experience. On a centralized platform like Instagram, for example, users have revolted against algorithm changes that they dislike, but there’s not much they can do to revert or improve upon an undesired app update.

Boston Dynamics’ Atlas Tries Out Inventory Work, Gets Better At Lifting

In a new video released today, Boston Dynamics’ Atlas robot is shown performing “kinetically challenging” work, like moving some medium-weight car parts and precisely picking stuff up. Ars Technica reports: In the latest video, we’re on to what looks like “phase 2” of picking stuff up — being more precise about it. The old clamp hands had a single pivot at the palm and seemed to just apply the maximum grip strength to anything the robot picked up. The most delicate thing Atlas picked up in the last video was a wooden plank, and it was absolutely destroying the wood. Atlas’ new hands look a lot more gentle than The Clamps, with each sporting a set of three fingers with two joints. All the fingers share one big pivot point at the palm of the hand, and there’s a knuckle joint halfway up the finger. The fingers are all very long and have 360 degrees of motion, so they can flex in both directions, which is probably effective but very creepy. Put two fingers on one side of an item and the “thumb” on the other, and Atlas can wrap its hands around objects instead of just crushing them.

Atlas is picking up a set of car struts — an object with extremely complicated topography that weighs around 30 pounds — so there’s a lot to calculate. Atlas does a heavy two-handed lift of a strut from a vertical position on a pallet, walks the strut over to a shelf, and carefully slides it into place. This is all in Boston Dynamics’ lab, but it’s close to repetitive factory or shipping work. Everything here seems designed to give the robot a manipulation challenge. The complicated shape of the strut means there are a million ways you could grip it incorrectly. The strut box has tall metal poles around it, so the robot needs to not bang the strut into the obstacle. The shelf is a tight fit, so the strut has to be placed on the edge of the shelf and slid into place, all while making sure the strut’s many protrusions won’t crash into the shelf.

Self-Proclaimed Bitcoin Inventor’s Claim ‘a Brazen Lie,’ London Court Told

In a London court, lawyers for a group supported by the Crypto Open Patent Alliance (COPA) argued that Craig Wright’s assertion of being the inventor of bitcoin is “a brazen lie,” challenged by accusations of extensive document forgery to substantiate his claim. Wright’s defense disputes these allegations, maintaining that he has presented definitive proof of his role in creating bitcoin. Reuters reports: Craig Wright says he is the author of a 2008 white paper, the foundational text of bitcoin and other cryptocurrencies, published in the name “Satoshi Nakamoto”. He argues this means he owns the copyright in the white paper and has intellectual property rights over the bitcoin blockchain. But the Crypto Open Patent Alliance (COPA) — whose members include Twitter founder Dorsey’s payments firm Block — is asking London’s High Court to rule that Wright is not Satoshi.

The five-week hearing, at which Wright will give evidence from Tuesday, is the culmination of years of speculation about the true identity of Satoshi. Wright first publicly claimed to be Satoshi in 2016 and has since taken legal action against cryptocurrency developers and exchanges. COPA, however, says Wright has never provided any genuine proof, accusing him of repeatedly forging documents to support his claim, which Wright denies. Wright sat in court as COPA’s lawyer Jonathan Hough said his claim was “a brazen lie, an elaborate false narrative supported by forgery on an industrial scale.” Hough said that “there are elements of Dr Wright’s conduct that stray into farce,” citing his alleged use of ChatGPT to produce forgeries.

But he added: “Dr Wright’s conduct is also deadly serious. On the basis of his dishonest claim to be Satoshi, he has pursued claims he puts at hundreds of billions of dollars, including against numerous private individuals.” Wright’s lawyer Anthony Grabiner, however, argued in court filings that he has produced “clear evidence demonstrating his authorship of the white paper and creation of bitcoin.” Grabiner added that it was “striking” that no one else had publicly claimed to be Satoshi. “If Dr Wright were not Satoshi, the real Satoshi would have been expected to come forward to counter the claim,” he said.

Dartmouth College Reinstates the SAT

Longtime Slashdot reader ardmhacha writes: After making the submission of SAT/ACT results optional (along with most other colleges in the U.S.) for admissions because of the disruptions due to COVID-19, Dartmouth announced that they will reinstate the standardized test requirement for applications to the Class of 2029 (admission in Fall 2025) and beyond. “Informed by new research, Dartmouth will reactivate the standardized testing requirement for undergraduate admission beginning with applicants to the Class of 2029,” reads an update to the college’s testing policy page.

A study conducted (PDF) by the college found that “SAT and ACT scores are highly predictive of academic performance at Dartmouth” and that “certain non-test score inputs in the admissions process, such as guidance counselor recommendations, do not predict college performance even though they do advantage more-advantaged applicants at IvyPlus institutions, increasing their admissions chances.” MIT had previously reinstated the SAT/ACT requirement.

Hugging Face Launches Open Source AI Assistant Maker To Rival OpenAI’s Custom GPTs

Carl Franzen reports via VentureBeat: Hugging Face, the New York City-based startup that offers a popular, developer-focused repository for open source AI code and frameworks (and hosted last year’s “Woodstock of AI”), today announced the launch of third-party, customizable Hugging Chat Assistants. The new, free product offering allows users of Hugging Chat, the startup’s open source alternative to OpenAI’s ChatGPT, to easily create their own customized AI chatbots with specific capabilities, similar both in functionality and intention to OpenAI’s custom GPT Builder â” though that requires a paid subscription to ChatGPT Plus ($20 per month), Team ($25 per user per month paid annually), and Enterprise (variable pricing depending on the needs).

Phillip Schmid, Hugging Face’s Technical Lead & LLMs Director, posted the news on the social network X (formerly known as Twitter), explaining that users could build a new personal Hugging Face Chat Assistant “in 2 clicks!” Schmid also openly compared the new capabilities to OpenAI’s custom GPTs. However, in addition to being free, the other big difference between Hugging Chat Assistant and the GPT Builder and GPT Store is that the latter tools depend entirely on OpenAI’s proprietary large language models (LLM) GPT-4 and GPT-4 Vision/Turbo. Users of Hugging Chat Assistant, by contrast, can choose which of several open source LLMs they wish to use to power the intelligence of their AI Assistant on the backend, including everything from Mistral’s Mixtral to Meta’s Llama 2. That’s in keeping with Hugging Face’s overarching approach to AI — offering a broad swath of different models and frameworks for users to choose between — as well as the same approach it takes with Hugging Chat itself, where users can select between several different open source models to power it.

Ask Slashdot: How Can I Stop Security Firms From Harvesting My Data?

Slashdot reader Unpopular Opinions requests suggestions from the Slashdot community:
Lately a boom of companies decided to play their “nice guy” card, providing us with a trove of information about our own sites, DNS servers, email servers, pretty much anything about any online service you host.

Which is not anything new… Companies have been doing this for decades, except as paid services you requested. Now the trend is basically anyone can do it over my systems, and they are always more than happy to sell anyone, me included, my data they collected without authorization or consent. It’s data they never had the rights to collect and/or compile to begin with, including data collected thru access attempts via known default accounts (Administrator, root, admin, guest) and/or leaked credentials provided by hacked databases when a few elements seemingly match…

“Just block those crawlers”? That’s what some of those companies advise, but not only does the site operator have to automate it themself, not all companies offer lists of their source IP addresses or identify them. Some use multiple/different crawler domain names from their commercial product, or use cloud providers such as Google Cloud, AWS and Azure â” so one can’t just block access to their company’s networks without massive implications. They also change their own information with no warning, and many times, no updates to their own lists. Then, there is the indirect cost: computing cost, network cost, development cost, review cycle cost. It is a cat-and-mice game that has become very boring.

With the raise of concerns and ethical questions about AI harvesting and learning from copyrighted work, how are those security companies any different from AI, and how could one legally put a stop on this?

Block those crawlers? Change your Terms of Service? What’s the best fix… Share your own thoughts and suggestions in the comments.

Disneyland’s New ‘Pixar Place’ Hotel is Like Visiting the Studio

The Orange County Register reports:

The new Pixar Place Hotel next door to Disneyland and Disney California Adventure is designed to look like you’ve walked onto the Pixar Animation Studios campus in Emeryville with concept drawings, character maquettes and final designs sprinkled throughout the hotel. “For those of you who are into the creative process, I think you’ll be really happy. This hotel really celebrates that,” Pixar Chief Creative Officer Pete Docter said during the opening ceremony for the hotel. “You get to see rough drawings, color studies and animation sketches as the animators were working. It really feels like you’re walking into Pixar in a way when you step in here.”

The multimillion-dollar transformation of the former Paradise Pier Hotel into the new Pixar Place Hotel debuted on Tuesday, January 30 after three years in the making at the Disneyland resort in Anaheim. The front lobby of the hotel is intended to feel like a gallery of curated artwork and custom creations inspired by Pixar’s famed studio in Northern California. The rear lobby takes visitors through the animated filmmaking process from hand-drawn sketches to wire-frame character designs. Red, yellow and blue bursts of primary colors serve as bold accents at the front desk in contrast to the muted colors of modern hotel designs.

More details from the Los Angeles Times:

The showcase piece of the lobby is a large mobile, situated above the Pixar lamp and ball, with abstracted, stained glass-like figures from “The Incredibles,” “Wall-E,” “Finding Nemo” and more. They are flanked by colored panels, which react to the music played in the area, an effect that is of course better seen in the evening.

“Pixar is a balance of sophistication and whimsy that really is core to their values,” said Kirstin Makela, an art director at Walt Disney Imagineering, the company’s secretive arm devoted to theme park experiences. “They’re a studio that’s been at the cutting edge of what they do. They take it very seriously that their characters are represented in that high esteem that they deserve because they are works of art. “So it really is about creating a space that feels like a living art gallery that allows for the work to be elevated and feel celebrated, and allows for the work to get that dynamic pop of color and energy,” Makela continued…

[I]ncluded in the rooms is the hardbound “The Art of Pixar” book, and various depictions of the Pixar lamp and ball, from an actual lamp on the desk to traces of the ball and the lamp in the bedding, carpeting and decorative pillows…

In a sampling of room rates throughout the year, I found nothing lower than $405 per night for a standard room, and about $100 more for high-traffic holiday months.

Will Microsoft Bring the Linux ‘Sudo’ Command to Windows Server?

An anonymous reader shared this report from BleepingComputer

Microsoft released the first Windows Server 2025 Insider preview build last week. However, soon after, a newer version was leaked online. As first reported by Windows Latest, the leaked version contains some new in-development features, including new settings for a Windows ‘sudo’ command.

These settings are only available after enabling developer mode, and the sudo command does not currently work from the command line yet, showing it is early in development. However, the sudo settings provide some clues as to how the command will work, with the ability to run sudo applications ‘In a new windows’, ‘With input disabled’, and ‘Inline’….

It is important to note that Microsoft commonly tests new features in preview builds that do not make it into the production builds.

Obligatory XKCD.

How CS Students Go From Code.org Into Its Founders’ Mentorship/Angel Investment Fund, ‘Neo’

The VC fund Neo “identifies awesome young engineers, includes them in a community of tech veterans, and invests in companies they start or join,”
TechCrunch explained in 2018.

Long-time Slashdot reader theodp notes that Neo is also benefiting from the education non-profit Code.org:

Eleven years ago, Neo Founder and CEO Ali Partovi together with twin brother Hadi (Code.org CEO and a Neo investor) publicly launched the nonprofit Code.org (backed and advised by big tech companies). With the support of prominent tech giant leaders and their companies, Code.org pushed coding into K-12 classrooms (NYT, alt.) and now boasts that “591,636 teachers have signed up to teach our intro courses on Code Studio and 19,177,297 students are enrolled,” helping to build a pipeline of “college students who excel at CS”. Neo taps into this pipeline, and it looks like others also betting on their success include Neo investors tied to Microsoft, Google, Meta, Amazon, and Uber — including Code.org boosters Bill Gates, Satya Nadella, Reid Hoffman, Jeff Wilke, Sheryl Sandberg, Eric Schmidt.

“I love meeting more and more @Neo founders and Neo scholar candidates who learned to code on Code.org,” Neo CEO Ali Partovi tweeted last summer.

in November Partovi welcomed “32 exceptional CS students” chosen from over 1,000 applicants to be Neo Scholars, “a year-long program of events, trips, and mentorship, as well as long-term membership in our community.”

James Cameron Loves Apple’s Vision Pro. But Will It Be Addictive?

James Cameron tells Vanity Fair’s Nick Bilton that his experience with Apple’s Vision Pro “was religious. I was skeptical at first. I don’t bow down before the great god of Apple, but I was really, really blown away… I think it’s not evolutionary; it’s revolutionary. And I’m speaking as someone who has worked in VR for 18 years.”

He explained that the reason it looks so real is because the Apple Vision Pro is writing a 4K image into my eyes. “That’s the equivalent of the resolution of a 75-inch TV into each of your eyeballs — 23 million pixels.” To put that into perspective, the average 4K television has around 8 million pixels. Apple engineers didn’t slice off a rectangle from the corner of a 4K display and put it in the Apple Vision Pro. They somehow compressed twice as many pixels into a space as small as your eyeball. This, to people like Cameron who have been working in this space for two decades, “solves every problem.”

But even with all this wonder, with 23 million pixels that are so clear and crisp that you can’t tell reality from a digital composite of it…. the more I’ve used the Apple Vision Pro over the past two weeks, the more one glaring problem revealed itself to me. It’s not the weight (which is a problem but will come down over time), or the size (which will shrink with each iteration), or the worry that it will drive us to consume more content alone (almost half of Americans already watch TV alone). Or how tech giants like Meta, Netflix, Spotify, and Google are currently withholding their apps from the device. (Content creators may come around once the consumers are there, and some, like Disney, are already embracing the device, making 150 movies available in 3D, including from mega-franchises like Star Wars and Marvel.) And it’s not even the price, because if Apple wanted to, the company could subsidize the cost of the Apple Vision Pro and it would have about as much financial impact as Cook losing a nickel between his couch cushions.

I’m talking about something that I don’t see a solution for… I can see a day when we all can’t imagine living without an augmented reality. When we’re enveloped more and more by technology, to the point that we crave these glasses like a drug, like we crave our iPhones today but with more desire for the dopamine hit this resolution of AR can deliver. I know deep down that the Apple Vision Pro is too immersive, and yet all I want to do is see the world through it. “I’m sure the technology is terrific. I still think and hope it fails,” one Silicon Valley investor said to me. “Apple feels more and more like a tech fentanyl dealer that poses as a rehab provider.” Harsh words, but he feels what we all feel, a slave to our smartphone, and he’s seen this play before and he knows what the first act is like, and the second act, and he knows how it ends.

Political blogger Taegan Goddard says the Vision Pro “offers a glimpse of how we might use computers in the future. If you’re skeptical — and many people are — you need to try it before drawing any conclusions. It’s hard to explain unless you’ve worn it. But I can assure you, it’s mind-blowing.”

Apple CEO Tim Cook tells Bilton “You can actually lay on your sofa and put the displays on your ceiling if you wish. I watched the third season of Ted Lasso on my ceiling and it was unbelievable!”

Dan Ives, a senior analyst at the investment firm Wedbush Securities, tells Bilton, “We think a few years from now it’ll resemble sunglasses and be less than $1,500.”
