Stripe To Start Taking Crypto Payments, Starting With USDC Stablecoin (techcrunch.com)

Fintech giant Stripe announced on Thursday that it would let customers accept cryptocurrency payments, starting with USDC stablecoins, initially only on Solana, Ethereum and Polygon. TechCrunch reports: This will be the first time that Stripe has taken crypto payments since 2018, when it dropped support for Bitcoin due to it being too unstable. Stripe in 2022 tried its first reentry into the crypto market when it announced payouts (but not payments) in USDC, with Twitter as its marquee customer for the service. Thursday's news has no customer names attached to it.

On Wednesday the company unveiled a long list of other launches, the most significant update being that Stripe, for the very first time, would let customers integrate competing payment providers with Stripe's other financial services tooling. Thursday's nod to expanding crypto support is also part of that bigger strategy to open up its walled garden. A brief timeline of Stripe's dance with crypto underscores the tricky line that Stripe has walked over the years when it comes to cryptocurrency. True to its disruptive roots as a fintech, the company has wanted to be in the middle of the conversation around how blockchain-based technologies will affect financial services. But it runs the risk of subverting its bigger business and positioning as a stable and sensible financial powerhouse if it dabbles too deeply or for too long in periods of instability. The company processed $1 trillion in transactions last year, and it's still growing; it is currently worth $65 billion on paper.

FCC Votes To Restore Net Neutrality Rules (nytimes.com) 12

An anonymous reader quotes a report from the New York Times: The Federal Communications Commission voted on Thursday to restore regulations that expand government oversight of broadband providersand aim to protect consumer access to the internet, a move that will reignite a long-running battle over the open internet. Known as net neutrality, the regulations were first put in place nearly a decade ago under the Obama administration and are aimed at preventing internet service providers like Verizon or Comcast from blocking or degrading the delivery of services from competitors like Netflix and YouTube. The rules were repealed under President Donald J. Trump, and have proved to be a contentious partisan issue over the years while pitting tech giants against broadband providers.

In a 3-to-2 vote along party lines, the five-member commission appointed by President Biden revived the rules that declare broadband a utility-like service regulated like phones and water. The rules also give the F.C.C. the ability to demand broadband providers report and respond to outages, as well as expand the agency's oversight of the providers' security issues. Broadband providers are expected to sue to try to overturn the reinstated rules.

The core purpose of the regulations is to prevent internet service providers from controlling the quality of consumers' experience when they visit websites and use services online. When the rules were established, Google, Netflix and other online services warned that broadband providers had the incentive to slow down or block access to their services. Consumer and free speech groups supported this view. There have been few examples of blocking or slowing of sites, which proponents of net neutrality say is largely because of fear that the companies would invite scrutiny if they did so. And opponents say the rules could lead to more and unnecessary government oversight of the industry.

Veteran PC Game 'Sopwith' Celebrates 40th Anniversary (github.io) 42

Longtime Slashdot reader sfraggle writes: Biplane shoot-'em up, Sopwith, is celebrating 40 years today since its first release back in 1984. The game is one of the oldest PC games still in active development today, originating as an MS-DOS game for the original IBM PC. The 40th anniversary site has a detailed history of how the game was written as a tech demo for the now-defunct Imaginet networking system. There is also a video interview with its original authors. "The game involves piloting a Sopwith biplane, attempting to bomb enemy buildings while avoiding fire from enemy planes and various other obstacles," reads the Wiki page. "Sopwith uses four-color CGA graphics and music and sound effects use the PC speaker. A sequel with the same name, but often referred to as Sopwith 2, was released in 1985."

What Comes After OLED? Meet QDEL (arstechnica.com) 49

An anonymous reader quotes a report from Ars Technica: Quantum dots are already moving in the premium display category, particularly through QD-OLED TVs and monitors. The next step could be QDEL, short for "quantum dot electroluminescent," also known as NanoLED, screens. Not to be confused with the QLED (quantum light emitting diode) tech already available in TVs, QDEL displays don't have a backlight. Instead, the quantum dots are the light source. The expected result is displays with wider color spaces than today's QD-OLEDs (quantum dot OLEDs) that are also brighter, more affordable, and resistant to burn-in. It seems like QDEL is being eyed as one of the most potentially influential developments for consumer displays over the next two years. If you're into high-end display tech, QDEL should be on your radar.

You may know QDEL as NanoLED because that's what Nanosys, a quantum dot supplier developing the technology, calls it. QDEL has gone by other names, such as QLED -- before Samsung claimed that acronym for LCD-LED TVs that use quantum dots. You may also see QDEL referred to as QD-EL, QD-LED, or EL-QD. As the alphabet soup suggests, there are still some things to finalize with this tech. This article will mostly use the term QDEL, with occasional references to NanoLED. If none of those names sound familiar, it's probably because you can't buy any QDEL products yet. Suppliers suggest that could change in the next few years; Nanosys is targeting 2026 for commercial availability. [...]

Today's OLED screens use OLED material as their light source, with QD-OLED specifically applying quantum dots to convert the light into color. In QLED, the light source is a white backlight; QDEL displays apply electricity directly to quantum dots, which then generate light. QDEL uses a layer of quantum dots sandwiched between an anode and cathode to facilitates the flow of electricity into the quantum dots. QDEL displays have pixels made of a red quantum dot subpixel, green quantum dot subpixel, and -- differing from today's QLED and QD-OLED displays -- blue quantum dot subpixel. QDEL displays use the same quantum dot cores that QD-OLED and QLED products use, [Jeff Yurek, Nanosys' VP of marketing] told me, adding, "The functionalization of the outer layer of the [quantum dots] needs to be changed to make it compatible with each display architecture, but the cores that do the heavy lifting are pretty much the same across all of these."

Because QDEL pixels make their own light and can therefore turn off completely, QDEL displays can deliver the same deep blacks and rich contrast that made OLED popular. But with the use of direct-view quantum dots, stakeholders are claiming the potential for wider color gamuts than we've seen in consumer displays before. With fewer layers and parts, there are also implications for QDEL product pricing, longevity, and even thinness. [...] The fact that quantum dots are already being successfully applied to LCD-LED and OLED screens is encouraging for future QDEL products. QDEL stakeholders claim that the tech could bring efficiencies like lower power consumption and higher brightness than OLED. (Research using a prototype device has recorded quantum dot light-emitting diodes reaching 614,000 nits. Of course, those aren't the type of results you should expect to see in a real-life consumer product.) There's also hope that QDEL could eventually last longer than OLED, especially since QDEL doesn't rely on organic materials that can cause burn-in.

The Ingenuity Mars Helicopter Just Sent Its Last Message Home (livescience.com) 27

Two months ago the team behind NASA's Ingenuity Helicopter released a video reflecting on its historic explorations of Mars, flying 10.5 miles (17.0 kilometers) in 72 different flights over three years. It was the team's way of saying goodbye, according to NASA's video.

And this week, LiveScience reports, Ingenuity answered back: On April 16, Ingenuity beamed back its final signal to Earth, which included the remaining data it had stored in its memory bank and information about its final flight. Ingenuity mission scientists gathered in a control room at NASA's Jet Propulsion Laboratory (JPL) in California to celebrate and analyze the helicopter's final message, which was received via NASA's Deep Space Network, made up of ground stations located across the globe.

In addition to the remaining data files, Ingenuity sent the team a goodbye message including the names of all the people who worked on the mission. This special message had been sent to Perseverance the day before and relayed to Ingenuity to send home.

The helicopter, which still has power, will now spend the rest of its days collecting data from its final landing spot in Valinor Hills, named after a location in J.R.R. Tolkien's "The Lord of the Rings" books.

The chopper will wake up daily to test its equipment, collect a temperature reading and take a single photo of its surroundings. It will continue to do this until it loses power or fills up its remaining memory space, which could take 20 years. Such a long-term dataset could not only benefit future designs for Martian vehicles but also "provide a long-term perspective on Martian weather patterns and dust movement," researchers wrote in the statement. However, the data will be kept on board the helicopter and not beamed back to Earth, so it must be retrieved by future Martian vehicles or astronauts.

"Whenever humanity revisits Valinor Hills — either with a rover, a new aircraft, or future astronauts — Ingenuity will be waiting with her last gift of data," Teddy Tzanetos, an Ingenuity scientist at JPL, said in the statement.

Thursday NASA's Jet Propulsion Laboratory released another new video tracing the entire route of Ingenuity's expedition over the surface of Mars.

"Ingenuity's success could pave the way for more extensive aerial exploration of Mars down the road," adds Spacae.com: Mission team members are already working on designs for larger, more capable rotorcraft that could collect a variety of science data on the Red Planet, for example. And Mars isn't the only drone target: In 2028, NASA plans to launch Dragonfly, a $3.3 billion mission to Saturn's huge moon Titan, which hosts lakes, seas and rivers of liquid hydrocarbons on its frigid surface. The 1,000-pound (450 kg) Dragonfly will hop from spot to spot on Titan, characterizing the moon's various environments and assessing its habitability.

NASA Veteran Behind Propellantless Propulsion Drive Announces Major Discovery (thedebrief.org) 258

Longtime Slashdot reader garyisabusyguy shares a report from The Debrief: Dr. Charles Buhler, a NASA engineer and the co-founder of Exodus Propulsion Technologies, has revealed that his company's propellantless propulsion drive, which appears to defy the known laws of physics, has produced enough thrust to counteract Earth's gravity. "The most important message to convey to the public is that a major discovery occurred," Buhler told The Debrief. "This discovery of a New Force is fundamental in that electric fields alone can generate a sustainable force onto an object and allow center-of-mass translation of said object without expelling mass." "There are rules that include conservation of energy, but if done correctly, one can generate forces unlike anything humankind has done before," Buhler added. "It will be this force that we will use to propel objects for the next 1,000 years until the next thing comes."

To document his team's discovery as well as the process behind their work, which Dr. Buhler cautions is in no way affiliated with NASA or the U.S. Government, the outwardly amiable researcher presented his findings at a recent Alternative Propulsion Energy Conference (APEC). Filled with both highly-credentialed career engineers and propulsion hobbyists, APEC is an organization The Debrief once referred to as the World's Most Exclusive (And Strange) Anti-Gravity Club. In conjunction with that presentation, "The Discovery of Propellantless Propulsion: The Direct Conversion of Electrical Energy into Physical Thrust," Dr. Buhler also sat down with APEC co-founder and moderator Tim Ventura to explain how his past in electrostatics, which is his primary area of expertise, ended up being a key component of his discovery of this new force. [...]

Up next, Buhler says his team is seeking funding to test their devices in space to better understand the force at work. "We're hoping to do some demos," said Buhler. "Some space demos. That's what we're trying to get some funding to do. I think that would be a great way to show off the technology." Besides proving once and for all that the force they are seeing is real, the accomplished engineer believes that such tests could encourage other scientists to search for an explanation of what exactly it is they are seeing. "I think it's a good opportunity for people to run these tests, look at them, watch them go in space, watch it move in space, and then say, "what does it imply? What are the implications?'" Until that time, Buhler says he believes his work proves that the force they are seeing is "fundamental" and that understanding it is the next logical step. "You can't deny this," he told Ventura. "There's not a lot to this. You're just charging up Teflon, copper tape, and foam, and you have this thrust."

So, while his team believes their experiments speak for themselves, the veteran scientist says he also believes it is the job of science to analyze and understand this discovery. If successful, he thinks it may even address some of the harder questions in science, including the nature of dark energy or even space/time itself. "It's easy to make these things," he said, "so it's a tool for the scientific community to use to try to explore those hard questions."
If there are companies or individuals interested in working with Exodus Propulsion Technologies, Buhler asks that they reach out via their LinkedIn page.

Android Gets a New Software-Based AV1 Decoder (9to5google.com) 13

Ben Schoon reports via 9to5Google: Google's Arif Dikici confirmed on LinkedIn this week that Android is now using VideoLAN's (the makers of VLC) "dav1d" software decoder to allow AV1 to work on more devices. This is now available on all devices running Android 12 or higher via a software update. Mishaal Rahman points out that this started to roll out with the March 2024 Google Play system update.

Dikici says that "most" devices can at least support 720p at 30 frames per second, but that apps will need to opt in "for now" to support AV1 via software decoding. One app that has opted in is YouTube, which now uses AV1 on all compatible devices (though it may have reverted this). This may result in increased power usage depending on your device, though. Improvements on that front may be coming, though, says VideoLAN on Twitter/X.

Reddit Is Taking Over Google (businessinsider.com) 86

An anonymous reader quotes a report from Business Insider: If you think you've been seeing an awful lot more Reddit results lately when you search on Google, you're not imagining things. The internet is in upheaval, and for website owners the rules of "winning" Google Search have never been murkier. Google's generative AI search engine is coming from one direction. It's creeping closer to mainstream deployment and bringing an existential crisis for SEOs and website makers everywhere. Coming from the other direction is an influx of posts from Reddit, Quora, and other internet forums that have climbed up through the traditional set of Google links. Data analysis from Semrush, which predicts traffic based on search ranking, shows that traffic to Reddit has climbed at an impressive clip since August. Semrush estimated that Reddit had over 132 million visitors in August 2023. At the time of publishing, it was projected to have over 346 million visitors in April 2024.

None of this is accidental. For years, Google has been watching users tack on "Reddit" to the end of search queries and finally decided to do something about it. Google started dropping hints in 2022 when it promised to do a better job of promoting sites that weren't just chasing the top of search but were more helpful and human. Last August, Google rolled out a big update to Search that seemed to kick this into action. Reddit, Quora, and other forum sites started getting more visibility in Google, both within the traditional links and within a new "discussions and forums" section, which you may have spotted if you're US-based. The timing of this Reddit bump has led to some conspiracy theories. In February, Google and Reddit announced a blockbuster deal that would let Google train its AI models on Reddit content. Google said the deal, reportedly worth $60 million, would "facilitate more content-forward displays of Reddit information," leading to some speculation that Google promised Reddit better visibility in exchange for the valuable training data. A few weeks later, Reddit also went public.

Steve Paine, marketing manager at Sistrix, called the rise of Reddit "unprecedented." "There hasn't been a website that's grown so much search visibility so quickly in the US in at least the last five years," he told Business Insider. Right now, Reddit ranks high for product searches. Reddit's main competitors are Wikipedia, YouTube, and Fandom, Paine said, and it also competes in "high-value commercial searches," putting it up against Amazon. The "real competitors," he said, are the subreddits that compete with brands on the web.
A Google spokesperson told Business Insider that the company is essentially just giving users what they want: "Our research has shown that people often want to learn from others' experiences with a topic, so we've continued to make it easier to find helpful perspectives on Search when it's relevant to a query. Our systems surface content from hundreds of forums and other communities across the web, and we conduct rigorous testing to ensure results are helpful and high quality."

Boston Dynamics' New Atlas Robot Is a Swiveling, Shape-Shifting Nightmare (theverge.com) 57

Jess Weatherbed reports via The Verge: It's alive! A day after announcing it was retiring Atlas, its hydraulic robot, Boston Dynamics has introduced a new, all-electric version of its humanoid machine. The next-generation Atlas robot is designed to offer a far greater range of movement than its predecessor. Boston Dynamics wanted the new version to show that Atlas can keep a humanoid form without limiting "how a bipedal robot can move." The new version has been redesigned with swiveling joints that the company claims make it "uniquely capable of tackling dull, dirty, and dangerous tasks."

The teaser showcasing the new robot's capabilities is as unnerving as it is theatrical. The video starts with Atlas lying in a cadaver-like fashion on the floor before it swiftly folds its legs backward over its body and rises to a standing position in a manner befitting some kind of Cronenberg body-horror flick. Its curved, illuminated head does add some Pixar lamp-like charm, but the way Atlas then spins at the waist and marches toward the camera really feels rather jarring. The design itself is also a little more humanoid. Similar to bipedal robots like Tesla's Optimus, the new Atlas now has longer limbs, a straighter back, and a distinct "head" that can swivel around as needed. There are no cables in sight, and its "face" includes a built-in ring light. It is a marked improvement on its predecessor and now features a bunch of Boston Dynamics' new AI and machine learning tools. [...] Boston Dynamics said the new Atlas will be tested with a small group of customers "over the next few years," starting with Hyundai.

Telegram Founder Accuses Google and Apple of Censorship Threat (youtube.com) 35

Pavel Durov, the founder of Telegram messaging app, has accused tech giants Google and Apple of threatening to censor content on smartphones [YouTube link]. In an interview with Tucker Carlson, Durov claimed that these companies told Telegram to comply with their guidelines or face removal from their app stores.

"Those two platforms, they could basically censor everything you can read, access on your smart phone," Durov said. With 900 million active users, Telegram is expected to cross the one billion mark within a year.

ISPs Can Charge Extra For Fast Gaming Under FCC's Internet Rules, Critics Say (arstechnica.com) 29

An anonymous reader quotes a report from Ars Technica: Some net neutrality proponents are worried that soon-to-be-approved Federal Communications Commission rules will allow harmful fast lanes because the plan doesn't explicitly ban "positive" discrimination. FCC Chairwoman Jessica Rosenworcel's proposed rules for Internet service providers would prohibit blocking, throttling, and paid prioritization. The rules mirror the ones imposed by the FCC during the Obama era and repealed during Trump's presidency. But some advocates are criticizing a decision to let Internet service providers speed up certain types of applications as long as application providers don't have to pay for special treatment. Stanford Law Professor Barbara van Schewick, who has consistently argued for stricter net neutrality rules, wrote in a blog post on Thursday that "harmful 5G fast lanes are coming."

"T-Mobile, AT&T and Verizon are all testing ways to create these 5G fast lanes for apps such as video conferencing, games, and video where the ISP chooses and controls what gets boosted," van Schewick wrote. "They use a technical feature in 5G called network slicing, where part of their radio spectrum gets used as a special lane for the chosen app or apps, separated from the usual Internet traffic. The FCC's draft order opens the door to these fast lanes, so long as the app provider isn't charged for them." In an FCC filing yesterday, AT&T said that carriers will use network slicing "to better meet the needs of particular business applications and consumer preferences than they could over a best-efforts network that generally treats all traffic the same."

Van Schewick warns that carriers could charge consumers more for plans that speed up specific types of content. For example, a mobile operator could offer a basic plan alongside more expensive tiers that boost certain online games or a tier that boosts services like YouTube and TikTok. Ericsson, a telecommunications vendor that sells equipment to carriers including AT&T, Verizon, and T-Mobile, has pushed for exactly this type of service. In a report on how network slicing can be used commercially, Ericsson said that "many gamers are willing to pay for enhanced gaming experiences" and would "pay up to $10.99 more for a guaranteed gaming experience on top of their 5G monthly subscription."

YouTube's Ad Blocker Crackdown Now Includes Third-Party Apps (theverge.com) 204

YouTube has updated its policies to no longer allow "third-party apps to turn off ads." The Verge reports: This appears to target mobile ad blockers like AdGuard, which lets you open YouTube within the ad blocking app, where you'll get to view videos interruption-free. "We only allow third-party apps to use our API when they follow our API Services Terms of Service," YouTube says. "When we find an app that violates these terms, we will take appropriate action to protect our platform, creators, and viewers." To get around this, YouTube once again suggests signing up for the ad-free YouTube Premium.

Disneyland Adds 'Stars Wars' Touches (and New Droids) for 'Season of the Force' Event (sfgate.com) 49

A monthslong "Star Wars"-themed festival called Season of the Force is now happening at Disneyland — including John Williams compositions in the Star Wars: Galaxy's Edge land during the park's fireworks. SFGate reports: Before the show starts, a voice rings through the land. "Black Spire Outpost has a long and colorful history of heroes and legends, Jedi and Sith, royalty and resistance," it says. "Those who would rule and those who refuse to bow. Here we celebrate that fiery spirit tonight." Then as the first fireworks fly into the sky, the majestic "Star Wars" music begins...

During the day, the land is overrun with tiny robots. Season of the Force also includes daily appearances from the new BDX Droids, cute little "explorer companions," per Disneyland, designed to assist with "exploration and research." These new audio-animatronics interact with guests, clicking and whirring with a surprising amount of personality.

Sabine Wren from "Ahsoka" is also making appearances in Galaxy's Edge during Season of the Force, and there are specialty food offerings in the land like the Celto Slush (a green, pandan-flavored horchata cold brew coffee drink) and the return of Dewback Chili Noodles (spicy fettuccine with ginger-spiced ground pork, broccolini stems and shredded red cabbage).

For the event, Disneyland's long-running Star Tours ride now includes appearances from the Mandalorian (and Grogu), Ahsoka, and Cassian Andor, according to the article. "Also back this year is Hyperspace Mountain, the seasonal overlay of Space Mountain that puts riders into an intergalactic fight between the Resistance and the First Order."

Stop 'Harmful 5G Fast Lanes', Legal Scholar Warns America's FCC (stanford.edu) 41

America's FCC votes on net neutrality April 25th. And the director of Stanford Law School's "Center for Internet and Society" (also a law professor) says mostly there's "much to celebrate" in the draft rules released earlier this month. Mobile carriers like T-Mobile, AT&T and Verizon that have been degrading video quality for mobile users will have to stop. The FCC kept in place state neutrality protections like California's net neutrality law, allowing for layers of enforcement. The FCC also made it harder for ISPs to evade net neutrality at the point where data enters their networks.
However, the draft rules also have "a huge problem." The proposed rules make it possible for mobile ISPs to start picking applications and putting them in a fast lane — where they'll perform better generally and much better if the network gets congested.

T-Mobile, AT&T and Verizon are all testing ways to create these 5G fast lanes for apps such as video conferencing, games, and video where the ISP chooses and controls what gets boosted. They use a technical feature in 5G called network slicing, where part of their radio spectrum gets used as a special lane for the chosen app or apps, separated from the usual internet traffic. The FCC's draft order opens the door to these fast lanes, so long as the app provider isn't charged for them.

They warn of things like cellphone plans "Optimized for YouTube and TikTok... Or we could see add-ons like Enhanced Video Conferencing for $10 a month, or one-time 24-hour passes to have Prioritized Online Gaming." This isn't imagination. The ISPs write about this in their blogs and press releases. They talk about these efforts and dreams openly at conferences, and their equipment vendors plainly lay out how ISPs can chop up internet service into all manner of fast lanes.

These kinds of ISP-controlled fast lanes violate core net neutrality principles and would limit user choice, distort competition, hamper startups, and help cement platform dominance. Even small differences in load times affect how long people stay on a site, how much they pay, and whether they'll come back. Those differences also affect how high up sites show in search results. Thus, letting ISPs choose which apps get to be in a fast lane lets them, not users, pick winners and losers online... [T]he biggest apps will end up in all the fast lanes, while most others would be left out. The ones left out would likely include messaging apps like Signal, local news sites, decentralized Fediverse apps like Mastodon and PeerTube, niche video sites like Dropout, indie music sites like Bandcamp, and the millions of other sites and apps in the long tail.

One subheading emphasizes that "This is not controversial," noting that "Even proposed Republican net neutrality bills prohibited ISPs from speeding up and slowing down apps and kinds of apps..." Yet "While draft order acknowledges that some speeding up of apps could violate the no-throttling rule, it added some unclear, nebulous language suggesting that the FCC would review any fast lanes case-by-case, without explaining how it would do that... Companies that do file complaints will waste years litigating the meaning of "unreasonably discriminatory," all the while going up against giant telecoms that stockpile lawyers and lobbyists."

"Net neutrality means that we, the people who use the internet, get to decide what we do online, without interference from ISPs. ISPs do not get to interfere with our choices by blocking, speeding up or slowing down apps or kinds of apps..."

They urge the FCC to edit their draft order before April 24 to clarify "that the no-throttling rule also prohibits ISPs from creating fast lanes for select apps or kinds of apps."

Code.org Launches AI Teaching Assistant For Grades 6-10 In Stanford Partnership (illinois.edu) 16

theodp writes: From a Wednesday press release: "Code.org, in collaboration with The Piech Lab at Stanford University, launched today its AI Teaching Assistant, ushering in a new era of computer science instruction to support teachers in preparing students with the foundational skills necessary to work, live and thrive in an AI world. [...] Launching as a part of Code.org's leading Computer Science Discoveries (CSD) curriculum [for grades 6-10], the tool is designed to bolster teacher confidence in teaching computer science." EdWeek reports that in a limited pilot project involving twenty teachers nationwide, the AI computer science grading tool cut one middle school teacher's grading time in half. Code.org is now inviting an additional 300 teachers to give the tool a try. "Many teachers who lead computer science courses," EdWeek notes, "don't have a degree in the subject -- or even much training on how to teach it -- and might be the only educator in their school leading a computer science course."

Stanford's Piech Lab is headed by assistant professor of CS Chris Piech, who also runs the wildly-successful free Code in Place MOOC (30,000+ learners and counting), which teaches fundamentals from Stanford's flagship introduction to Python course. Prior to coming up with the new AI teaching assistant, which automatically assesses Code.org students' JavaScript game code, Piech worked on a Stanford Research team that partnered with Code.org nearly a decade ago to create algorithms to generate hints for K-12 students trying to solve Code.org's Hour of Code block-based programming puzzles (2015 paper [PDF]). And several years ago, Piech's lab again teamed with Code.org on Play-to-Grade, which sought to "provide scalable automated grading on all types of coding assignments" by analyzing the game play of Code.org students' projects. Play-to-Grade, a 2022 paper (PDF) noted, was "supported in part by a Stanford Hoffman-Yee Human Centered AI grant" for AI tutors to help prepare students for the 21st century workforce. That project also aimed to develop a "Super Teaching Assistant" for Piech's Code in Place MOOC. LinkedIn co-founder Reid Hoffman, who was present for the presentation of the 'AI Tutors' work he and his wife funded, is a Code.org Diamond Supporter ($1+ million).
In other AI grading news, Texas will use computers to grade written answers on this year's STAAR tests. The state will save more than $15 million by using technology similar to ChatGPT to give initial scores, reducing the number of human graders needed.

The US is Right To Target TikTok, Says Vinod Khosla (ft.com) 90

Vinod Khosla, the founder of venture capital firm Khosla Ventures, opines on the bill that seeks to ban TikTok or force its parent firm to divest the U.S. business: Even if one could argue that this bill strikes at the First Amendment, there is legal precedent for doing so. In 1981, Haig vs Agee established that there are circumstances under which the government can lawfully impinge upon an individual's First Amendment rights if it is necessary to protect national security and prevent substantial harm. TikTok and the AI that can be channelled through it are national and homeland security issues that meet these standards.

Should this bill turn into law, the president would have the power to force any foreign-owned social media to be sold if US intelligence agencies deem them a national security threat. This broader scope should protect against challenges that this is a bill of attainder. Similar language helped protect effective bans on Huawei and Kaspersky Lab. As for TikTok's value as a boon to consumers and businesses, there are many companies that could quickly replace it. In 2020, after India banned TikTok amid geopolitical tensions between Beijing and New Delhi, services including Instagram Reels, YouTube Shorts, MX TakaTak, Chingari and others filled the void.Â

Few appreciate that TikTok is not available in China. Instead, Chinese consumers use Douyin, the sister app that features educational and patriotic videos, and is limited to 40 minutes per day of total usage. Spinach for Chinese kids, fentanyl -- another chief export of China's -- for ours. Worse still, TikTok is a programmable fentanyl whose effects are under the control of the CCP.

The Courts

Cox Plans To Take Piracy Liability Battle To the Supreme Court (torrentfreak.com) 70

An anonymous reader quotes a report from TorrentFreak: Cox Communications doesn't believe that ISPs should be held liable for the activities of their pirating subscribers. After a disappointing verdict from a Virginia jury and an unsatisfactory outcome at the Court of Appeals, the internet provider now intends to escalate the matter to the Supreme Court. If the present verdict stands, innocent people risk losing their Internet access, the ISP notes. [...] That's notable, as it would be the first time that a "repeat infringer" case ends up at the highest court United States. Cox asked the court of appeals to also stay its mandate pending its Supreme Court application, as this could steer the legal battle in yet another direction.

According to Cox, the Supreme Court has substantial reasons to take on the case. For one, there are currently conflicting court of appeals rulings on the "material contribution" aspect of copyright infringement. The Supreme Court could give more clarity on when a service, with a myriad of lawful uses, can be held liable for infringers. In addition, Cox also cites the recent 'Twitter vs. Taamneh' Supreme Court ruling, which held that social media platforms aren't liable for terrorists who use their network. While that's not a copyright case, it's relevant for the secondary liability question, the ISP argues. "Though Twitter was not a copyright case, it confronted a directly analogous theory of secondary liability: that social-media platforms, including Twitter and YouTube, could be liable for continuing to provide services to those they knew were using them for illegal purposes," Cox writes.

Finally, Cox notes that the Supreme Court should hear the case because it deals with an issue that's 'exceptionally important' to ISPs as well as the public. If the present verdict stands, Internet providers may be much more likely to terminate Internet access, even if the subscriber is innocent. "This Court's material-contribution standard provides powerful incentives for ISPs of all stripes to swiftly terminate internet services that have been used to infringe -- no matter the universe of lawful uses to which those services are put, or the consequences to innocent, non-infringing people who also use those services. "That is why a chorus of amici urged this Court not to adopt this standard at the panel and en banc stages, and will likely urge the Supreme Court to grant review as well," Cox adds, referring to the support it received from third-parties previously.
"Cox hasn't filed a writ of certiorari yet and still has time, as it's due June 17, 2024," notes TorrentFreak. "The intention to go to the Supreme Court would be another reason to halt the new damages trial, according to Cox, but the court of appeals rejected the request."

"This means that the new damages trial can start, even if the case is still pending at the Supreme Court. However, it's clear that this legal battle is far from over yet."

ULA Launches Final Delta Rocket After 64 Years (space.com) 22

After 64 years of service, ULA on Tuesday launched its last-ever Delta rocket carrying a classified payload for the U.S. National Reconnaissance Office (NRO). "The powerful booster departed Space Launch Complex-37 (SLC-37) at Cape Canaveral Space Force Station in Florida at 12:53 p.m. EDT (1653 GMT), literally setting itself on fire for the 16th and final time," reports Space.com. From the report: That spectacle, which was unique to the Delta IV in its heaviest configuration, was the result of hydrogen building up in the flame trench and then rising up alongside the rocket after it was used to cool down the three RS-68A engines to cryogenic temperatures. When the engines fired, the hydrogen ignited and flames lapped at the orange insulation covering the core stage and its two side-mounted boosters. The two boosters were jettisoned about four minutes into the flight, followed by the core, or first stage, separating one minute and 45 seconds later. A single RL10C-2-1 engine on the Delta cryogenic second stage then took over, propelling the NROL-70 payload into space. Due to national security concerns, coverage of the launch ceased following fairing jettison at about 6 minutes and 40 seconds into the flight.

ULA is retiring the Delta IV, and eventually its other legacy rocket, the Atlas V, in favor of its newly introduced Vulcan, which flew a near-perfect first mission in January. The Vulcan was developed to replace both long-flying rockets in all of their configurations. "This is a great mission to think about that transition, because national security space missions is our core and the unique set of missions there require a high-energy launch vehicle. We designed Vulcan specifically for that," said [Tory Bruno, chief executive officer of United Launch Alliance]. In addition to being the 16th Delta IV Heavy, Tuesday's launch was also the 45th liftoff of a Delta IV, the 35th Delta IV to fly from Florida and the 389th Delta launch of any kind since 1960 (of which 294 were sent skyward from Cape Canaveral). Half of the Delta IV Heavy launches were devoted to sending NRO payloads into orbit. The rocket and its less powerful configurations were also used in support of NASA, NOAA (the U.S. National Oceanic and Atmospheric Administration), U.S. Air Force and commercial payloads.

Nine of the 10 Most-Watched Streaming Programs Are Reruns (bloomberg.com) 215

Despite investing billions in new streaming services, media giants have failed to dethrone old favorites, according to Nielsen data. The 21-year-old legal drama "NCIS" tops the list, with viewers streaming 11.4 million episodes per week. Netflix dominates the top 10, with eight shows owing most of their viewership to the platform. Reruns from CBS and other networks make up the majority of the list, with "Stranger Things" being the only original series.

"Nine of the 10 most-watched streaming programs are reruns. In addition to the three from CBS, there is one from YouTube (CoComelon), one from Canada (Heartland), one from Australia (Bluey) and Suits. The only original series to crack the list is Stranger Things," Bloomberg writes. However: "While reruns dominate the top 10, that is not the case overall. Most of the 100 most popular titles of the last three years are original series," it added.

VCs Invest $90M in Varda Space Industries' Microgravity Drug Manufacturing (techcrunch.com) 20

"Varda Space Industries has closed a massive tranche of funding," reports TechCrunch, "just weeks after its first drug manufacturing capsule returned from orbit."

Varda has now raised $145 million to date, the article points out, and the $90 million in new Series B funding "marks an inflection point for the company, which is now gearing up to scale from the initial demonstration mission to a regular set of missions carrying customer payloads, Varda founder Delian Asparouhov told TechCrunch." El Segundo-based Varda was founded in 2021 by Asparouhov, who is also a partner at Founders Fund, and Will Bruey, a spacecraft engineer who cut his teeth at SpaceX. The pair had an audacious goal to commercialize what until very recently was promising but ultimately small-scale research into the effects of microgravity on pharmaceutical crystals... Astronauts have been conducting protein crystallization experiments in space for decades on the International Space Station and before that, the Space Shuttle. But the business case for expanding this research has never materialized — until now...

Part of the reason Varda is possible today is due to the availability of regular, low-cost rideshare launches from SpaceX and Rocket Lab's innovations in satellite bus manufacturing. Even beyond these external partnerships, the startup has made significant headway in its own right, as the success of the first mission showed: Their reentry capsule appears to have performed flawlessly and the experiment to reformulate the HIV medicine ritonavir was executed without a hitch, it says. Varda has also started publishing the results of its internal R&D efforts, including a scientific paper on its hyper-gravity (as opposed to microgravity) crystallization platform, which the startup developed as a sort of screening method prior to sending drugs to space. [The paper is titled "Gravity as a Knob for Tuning Particle Size Distributions of Small Molecules."] It's an entirely new field of research that takes advantage of the ability to truly unlock gravity as a variable in scientific experiments. "Over time, we will be able to generate data sets between both hyper-gravity and microgravity and start to show correlations," he said....

In a recent podcast appearance, he specified that the all-in initial mission cost around $12 million, which will drop to $5-6 million by mission 4 and $2.5 million or less by mission 10.) Larger capsules are also in the longer-term pipeline, though also not until the 2027 time frame. Asparouhov also confirmed that pharmaceuticals will be Varda's sole focus for the next 10-20 (or more) years, based on the company's conviction that pharmaceutical products will generate more economic value compared to other materials. A lot of that comes down to the fact that there are a significant set of drugs that require only a "seed" of the material that can only be made in microgravity, and the rest of the drug formulation can be completed here on Earth...

The company is also aiming to improve the processing capabilities of the on-board pharmaceutical reactor. The first mission carried just one drug protein, but in the future the company hopes to process multiple drug products that could be run through different processing regimes. In the future, other missions could carry larger reactors for drugs that do need more than the "seed" crystal, and those mission profiles would be closer to something like mass manufacturing.

Varda already has "a handful" of signed contracts with biotech companies, according to the article — and Varda's next manufacturing mission "will launch later this year."
