As AMD flexes its muscles in the AI game, it is not only introducing new hardware but is betting on software too, trying to hit new market segments not already dominated by Nvidia. 

Thus, AMD has unveiled its first small language model, AMD-135M, which belongs to the Llama family and is aimed at private business deployments. It is unclear whether the new model has to do anything with the company's recent acquisition of Silo AI (as the deal has to be finalized and cleared by various authorities, so probably not), but this is a clear step in the direction of addressing the needs of specific customers with a pre-trained model done by AMD - using AMD hardware for inference.  

The main reason why AMD's models are fast is because they use so-called speculative decoding. Speculative decoding introduces a smaller 'draft model' that generates multiple candidate tokens in a single forward pass. Tokens are then passed to a larger, more accurate 'target model' that verifies or corrects them. On the one hand, this approach allows for multiple tokens to be generated simultaneously, yet on the other hand this comes at the cost of power due to increased data transactions.  

[...] AMD believes that further optimizations can lead to even better performance. Yet, as the company shares benchmark numbers of its previous-generation GPUs, we can only imagine what its current-generation (MI300X) and next-generation (MI325X) could do.

Oracle could choose to take control of Ampere Computing, the Arm processor designer it has backed and uses in its cloud.

A proxy statement [PDF] filed on Wednesday reveals that Oracle held 29 percent stake in Ampere as of May 31, 2024, and has the option to gain majority control over the chip house in 2027.

"The total carrying value of our investments in Ampere, after accounting for losses under the equity method of accounting, was $1.5 billion as of May 31, 2024," the filing reads.

Oracle also revealed it extended $600 million in loans in the form of convertible debt to Ampere during its 2024 fiscal year, on top of $400 million in debt given during the prior fiscal year.

Ampere's debts are set to mature beginning June 2026, when Oracle will have the option of converting those investments into additional equity in the chip startup. "If either of such options is exercised by us or our co-investors, we would obtain control of Ampere and consolidate its results with our results of operations," the filing explains.

According to the document, Oracle spent roughly $48 million on Ampere processors during its 2023 fiscal year – some of it direct with Ampere and some through a third party. By comparison, Big Red spent just $3 million on Ampere's chips and had $101.1 million worth of products available under a pre-payment order by the end of fiscal year 2024.

This is despite the fact that Oracle is aggressively expanding its datacenter footprint to address growing demand for AI infrastructure. These efforts have included the deployment of massive clusters of GPUs from Nvidia and AMD with the largest campus developments nearing a gigawatt in scale.

[...] Despite being one of the first to successfully commercialize an Arm-compatible datacenter-grade microprocessor – and winning customers including Microsoft and Google – Ampere faces growing competition not only from the likes of Intel and AMD, but its own customers.

To compete with Ampere's 192-core chips, Intel and AMD have competing products with 128 to 288 cores. Meanwhile, Microsoft and Google have announced custom Arm silicon of their own with their Cobalt and Axion chips respectively. Meanwhile, Arm itself has been pushing its Compute Subsystems (CSS) offering for customers that want a customized chip but can't be bothered to design one from the core up.

SpaceX celebrated the first human spaceflight from its Cape Canaveral launch site on Saturday, and while the two humans aboard the Crew Dragon Freedom are safely on their way to the International Space Station, a problem arose with the rocket's second stage that prompted the company to shut down future launches for now.

"After today's successful launch of Crew-9, Falcon 9's second stage was disposed in the ocean as planned, but experienced an off-nominal deorbit burn," SpaceX posted on X. "As a result, the second stage safely landed in the ocean, but outside of the targeted area. We will resume launching after we better understand [the] root cause."

The first victim of the shutdown was a planned launch Sunday from California of a Falcon 9 with a plan to send up the OneWeb Launch 20 mission for EutelsatGroup.

The Federal Aviation Administration still has that launch on its operations plan advisory for as early as Oct. 1, but the last two times SpaceX had an "off-nominal" issue with a Falcon 9 launch, the FAA had grounded the rocket.

The most recent was a fiery landing of a Falcon 9's first-stage booster last month during a Starlink mission.

"The FAA investigates commercial space incidents to determine the root cause and identify corrective actions so they won't happen again," the FAA said in a statement after that incident.

[...] Any significant delay in launches could affect the upcoming Falcon Heavy launch of NASA's Europa Clipper mission to send a massive satellite to Jupiter's icy moon Europa.

That flight is slated to fly as early as Oct. 10 from Kennedy Space Center's Launch Complex 39-A.

The M87 galaxy is monstrous.

It contains several trillions of stars, compared to our Milky Way's hundreds of billions. And the supermassive black hole at its center is shooting an outstretched beam of energy into space. The Hubble Space Telescope, operated by NASA and the European Space Agency, has captured a new image of this energetic cosmic event, which produces a beam of superheated gas 3,000 light-years long (a single light-year is nearly 6 trillion miles).

NASA calls this jet "blowtorch-like," and it seems to be triggering many stars near its trajectory to erupt.

"We don't know what's going on, but it's just a very exciting finding," Alec Lessing of Stanford University, who led the research into the finding, said in an agency statement. "This means there's something missing from our understanding of how black hole jets interact with their surroundings."

In the Hubble telescope image below, the colossal elliptical galaxy M87, which is shaped like a giant egg, looks like "a translucent, fuzzy white cotton ball," ESA explained. The jet, as you can see, is the wavy blue beam blasting out from the galactic core, home to the supermassive black hole (it has the mass of 5.4 billion suns).

As the jet shoots through the galaxy, astronomers suspect it's triggering a type of stellar explosion called a "nova." These eruptions happen in double-star systems with an aging star — which is bloated and shedding its layers — and a white dwarf star, which is the hot core of a sun-like star that has shed its mass. The swollen star dumps material (hydrogen) on the white dwarf. "When the dwarf has tanked up a mile-deep surface layer of hydrogen that layer explodes like a giant nuclear bomb," the agency explained. And then the gradual process renews.

Beijing has published its proposed regulations for satellite broadband, including a requirement that operators conduct censorship in real time.

In its latest draft rules, the Cyberspace Administration of China proposes any organization or individual using terminal equipment with direct connection to satellite services is not allowed to "produce, copy, publish, or disseminate content prohibited by laws and administrative regulations, such as content that incites subversion of state power, overthrows the socialist system, endangers national security and interests, damages the national image, incites secession of the country, undermines national unity and social stability, promotes terrorism, extremism, ethnic hatred, ethnic discrimination, violence, pornography, and false information."

It clarifies that terminal equipment includes civilian handheld, portable, and fixed terminals, as well as terminals installed on aircraft, ships, and vehicles – essentially any device that enables users to access satellite communication systems for voice calls, text messaging, and data exchange.

The document states that providers must align their operations with national security and network security requirements, and prevent illegal activities.

This includes complying with China's cyber security, data security, and personal information protection laws – plus potentially being responsible for users' activities.

"If a terminal equipment direct satellite service provider finds that a user has published or transmitted information prohibited by laws and regulations, it shall immediately stop the transmission, take measures such as elimination in accordance with the law, preserve relevant records, and report to the relevant competent authorities," stipulates the CAC.

The draft rules further include articles that would make tracking of providers and users easier. This includes requiring providers to:

• Obtain licenses and approvals, whether telco, radio frequency related or otherwise;
• Collect real identity information from those using its services, as China already requires of telcos;
• Integrate monitoring and supervision into their platforms to allow Beijing's oversight;
• Locate ground facilities – such as gateway stations and Earth stations – and user data on Chinese soil. Any data that does need to go overseas must be processed through a gateway approved by the telecommunications regulatory department of the State Council.

The rules even go so far as to require anyone who uses satellite broadband to publish news – or distribute video and audio content – to obtain a license.

YouTube Blocks Videos From Adele, Green Day, Bob Dylan, Others in Dispute With SESAC

YouTube blocks videos from Adele, Green Day, Bob Dylan, others in dispute with SESAC:

A number of YouTube videos featuring music from artists such as Adele, Green Day, Bob Dylan, Nirvana, and R.E.M. have been unplayable in the United States since Saturday.

For example, if you try to play Dylan's "Like A Rolling Stone" (whether it's the classic album recording or a live performance), you are instead told: "This video contains content from SESAC. It is not available in your country." Sometimes, you even get to watch a pre-roll ad before you see the message.

However, not all videos featuring these artists are blocked; it's not clear whether the playable videos are exempt from the current dispute or if they've simply been overlooked.

In statements to the press and on social media, YouTube blamed the situation on failed negotiations with SESAC, a performing rights group that says it represents more than 35,000 music artists and publishers.

"Unfortunately, despite our best efforts, we were unable to reach an equitable agreement before its expiration," YouTube said. "We take copyright very seriously and as a result, content represented by SESAC is no longer available on YouTube in the US. We are in active conversations with SESAC and are hoping to reach a new deal as soon as possible."

The situation echoes a dispute between Universal Music Group and TikTok earlier this year, which saw UMG pull songs by artists including Taylor Swift, Billie Eilish and Ariana Grande from the short-form video platform while it was negotiating over royalties.

Unlike UMG, SESAC isn't a record label, but rather an organization that collects royalties for songwriters and publishers, similar to ASCAP and BMI. In addition to the artists mentioned above, it also represents Burna Boy, George Clinton, Kenny Rogers, Kings of Leon, and many others.

The value of X (formerly Twitter) continues to circle the toilet at an impressive rate.

The social media platform is now worth 79 percent less than what it was worth when Elon Musk purchased it, according to analysis by investor Fidelity.

The financial platform should know what it's talking about, too, because it helped Musk acquire X back in 2022 and owns a stake in the company. Fidelity's initial investment, per TechCrunch, was $19.66 million. Fidelity's latest financial report, meanwhile, lists the value of its X stake as $4,185,614.

That's a yikes-inducing decrease of around 79 percent.

In fairness, the writing has been on the wall for a while. In January 2024 Fidelity already valued its stake in X at 71.5 percent less, and recent documents made it clear just how much X's revenue has plummeted. Meanwhile, a new report has suggested that advertisers — who were already fleeing Musk's platform en masse — are planning to spend even less on X in 2025.

Elsewhere Brazil is battling the platform, and the number of X users in the U.S. and the UK is decreasing.

Not looking great, is it?

Several sites, including OS Technix, are reporting that Arch will be collaborating with Valve. A heavily modified in-house Arch distro is used by Valve for SteamOS.

In an exciting development for the Linux community, Arch Linux has announced a new partnership with Valve, the company behind the Steam gaming platform and Steam Deck. This collaboration will see Valve financially support two major projects for Arch Linux: an improved build service infrastructure and a secure signing enclave.

[...] By providing freelance backing, Valve's support allows Arch Linux to work on these critical projects without being hindered by limitations in volunteer time. This will significantly accelerate progress and enable the Arch Linux team to tackle ambitious endeavours that would have otherwise taken much longer.

The collaboration will lead to the development of a robust build service infrastructure. This infrastructure will involve servers for building software, potentially similar to continuous integration systems. The system will likely manage compiling and distributing software, simplifying the process and reducing the need for custom setups for different devices.

The introduction of a secure signing enclave marks a significant advancement in security for Arch Linux. This enclave will leverage code signing to provide a higher level of assurance that packages downloaded from the official repositories haven't been tampered with. Users will be able to cryptographically verify the origin and integrity of software packages, making it much harder for malicious actors to distribute compromised software.

There is speculation that Valve might publicly release SteamOS in the future or that native support for games on GNU/Linux will improve greatly.

Last week, the House approved a resolution to block the Biden administration's emissions rule that would require more than half of the automobiles sold in the new-car market to be electric by 2032. The 215 representatives who voted for the bill, including eight Democrats, are far more in tune with most of the country than the White House:

Nationwide, the inventory of unsold EVs had grown by nearly 350% over the first half of 2024, creating "a 92-day supply — roughly three months' worth of EVs, and nearly twice the industry average," says Axios, which is 54 days for gasoline-powered vehicles.

Ford, which lost nearly $73,000 on each EV it sold in the second quarter of 2023, continues to yield to reality, now ditching its plans to build a large electric SUV. This "course change," says Just the News, "comes amid lower-than-expected demand for electric vehicles."

[...] "Based on where the market is and where the customer is, we will pivot and adjust and make those tough decisions," said John Lawler, Ford's chief financial officer.

[...] "Of the U.S. consumers planning on purchasing a new vehicle in the next 24 months, only 34% intend to purchase an EV, down 14% from 48% in the 2023," says Ernst & Young's Mobility Consumer Index, "a global survey of almost 20,000 consumers from 28 countries."

The story is much the same in Britain. EVs "are losing value at an 'unsustainable' rate as a slowdown in consumer demand sends used car prices tumbling," the Telegraph reported last week. Meanwhile in France, "the EU's second largest market for battery electric vehicles behind Germany," deliveries have fallen by a third.

Germans are likewise losing interest, as the country has "suffered a 'spectacular' drop in electric car sales as the European Union faces growing calls to delay its net zero vehicle targets," the Telegraph said in a separate story.

There are few bigger names in the world of motorcycles than Harley-Davidson. The brand has been churning out two-wheeled classics left and right for over a century, cultivating a fanbase like no other. Along the way, Harley-Davidson has seen some incredibly important moments in its company history arise, in addition to plenty that have fallen by the wayside. Seeing as it's rarely talked about in the modern era, it's no stretch to say that one of these overlooked points on the Harley timeline is the brand's brief foray into lawn mower technology.

Yes, as it was making its name as one of the United States' foremost motorcycle manufacturers, Harley-Davidson took a detour into landscaping territory. Way back in 1929, the company began providing single cylinder side-valve engines for the Worthington Mower Company's Overgreen lawn mowers. These massive mowers were used commercially to cut large swaths of grass like golf courses. Harley's engines powered them throughout the Great Depression, though the motorcycle giant didn't stick with lawn mowers for the long haul. Thus, it was never destined to sit alongside the best and worst major lawn mower brands.

It has been nearly 100 years since Harley-Davidson's Worthington collaboration came and went, yet some folks are still keen on trying to power their mowers with the bike favorite's technology.

With modern perceptions of Harley-Davidson as strictly a motorcycle brand, the idea of it contributing to the Worthington Mower Company's Overgreen lawn mowers sounds absurd. After all, throughout its century-long history, it has only branched out to create non-motorcycle products a few times. For instance, it created the LR-64 drone rocket engine for the U.S. military, and took a dip in the marine technology pool with its purchase of the Tomahawk Boating Company in 1961. Still, this hasn't prevented some folks from trying to bring its modern tech to back to the realm of landscaping.

Over on YouTube, Specialised Motorcycle Transport showcased what a modern lawn mower could look like with a Harley engine inside. It looks like a conventional riding mower with some unique aesthetic touches, but sounds just like motorcycle and is designed to get the speed of one too. This contraption was constructed for racing purposes rather than lawn maintenance. MrOildale on YouTube featured a similar piece on their channel. This orange riding mower — dubbed the "mower cycle" — came equipped with a 1,500cc Harley engine, certainly making it better suited for the racetrack than for cutting grass. It more than likely can't outrun the fastest Harley-Davidson motorcycles ever built, but it'll leave most average riding mowers out there in the dust.

Odds are Harley-Davidson's efforts in terms of lawn mowing are long over, but so long as mechanics can make its engines compatible with the latest riding mowers, chances are its legacy in the space will endure well into the future.

In an earlier article, I discussed a few of the flaws in Europe’s flagship data privacy law, the General Data Protection Regulation (GDPR). Building on that critique, I would now like to go further, proposing specifications for developing a robust privacy protection regime in the US.

Writers must overcome several hurdles to have a chance at persuading readers about possible flaws in the GDPR. First, some readers are skeptical of any piece criticizing the GDPR because they believe the law is still too young to evaluate. Second, some are suspicious of any piece criticizing the GDPR because they suspect that the authors might be covert supporters of Big Tech’s anti-GDPR agenda. (I can assure readers that I am not, nor have I ever, worked to support any agenda of Big Tech companies.)

In this piece, I will highlight the price of ignoring the GDPR. Then, I will present several conceptual flaws of the GDPR that have been acknowledged by one of the lead architects of the law. Next, I will propose certain characteristics and design requirements that countries like the United States should consider when developing a privacy protection law. Lastly, I provide a few reasons why everyone should care about this project.

People sometimes assume that the GDPR is mostly a “bureaucratic headache”—but this perspective is no longer valid. Consider the following actions by administrators of the GDPR in different countries.

In other words, the GDPR is not merely a bureaucratic matter; it can trigger hefty, unexpected fines. The notion that the GDPR can be ignored is a fatal error.

Axel Voss is one of the lead architects of the GDPR. He is a member of the European Parliament and authored the 2011 initiative report titled “Comprehensive Approach to Personal Data Protection in the EU” when he was the European Parliament's rapporteur. His call for action resulted in the development of the GDPR legislation. After observing the unfulfilled promises of the GDPR, Voss wrote a position paper highlighting the law's weaknesses. I want to mention nine of the flaws that Voss described.

First, while the GDPR was excellent in theory and pointed a path toward the improvement of standards for data protection, it is an overly bureaucratic law created largely using a top-down approach by EU bureaucrats.

Second, the law is based on the premise that data protection should be a fundamental right of EU persons. Hence, the stipulations are absolute and one-sided or laser-focused only on protecting the "fundamental rights and freedoms" of natural persons. In making this change, the GDPR architects have transferred the relationship between the state and the citizen and applied it to the relationship between citizens and companies and the relationship between companies and their peers. This construction is one reason why the obligations imposed on data controllers and processors are rigid.

Third, the GDPR law aims to empower the data subjects by giving them rights and enshrining these rights into law. Specifically, the law enshrines nine data subject rights into law. They are: the right to be informed, the right to access, the right to rectification, the right to be forgotten/or to erasure, the right to data portability, the right to restrict processing, the right to object to the processing of personal data, the right to object to automated processing and the right to withdraw consent. As with any list, there is always a concern that some rights may be missing. If critical rights are omitted from the GDPR, it would hinder the effectiveness of the law in protecting privacy and data protection. Specifically, in the case of the GDPR, the protected data subject rights are not exhaustive.

Fourth, the GDPR is grounded on a prohibition and limitation approach to data protection. For example, the principle of purpose limitation excludes chance discoveries in science. This ignores the reality that current technologies, e.g., machine learning and artificial Intelligence applications, function differently. Hence, these old data protection mindsets, such as data minimization and storage limitation, are not workable anymore.

SpaceX launches rescue mission for NASA astronauts stuck in space until next year:

CAPE CANAVERAL, Fla. — SpaceX launched a rescue mission for the two stuck astronauts at the International Space Station on Saturday, sending up a downsized crew to bring them home but not until next year.

[...] Since NASA rotates space station crews approximately every six months, this newly launched flight with two empty seats reserved for Wilmore and Williams won't return until late February. Officials said there wasn't a way to bring them back earlier on SpaceX without interrupting other scheduled missions.

By the time they return, the pair will have logged more than eight months in space. They expected to be gone just a week when they signed up for Boeing's first astronaut flight that launched in June.

[...] Williams has since been promoted to commander of the space station, which will soon be back to its normal population of seven. Once Hague and Gorbunov arrive this weekend, four astronauts living there since March can leave in their own SpaceX capsule. Their homecoming was delayed a month by Starliner's turmoil.

Hague noted before the flight that change is the one constant in human spaceflight.

"There's always something that is changing. Maybe this time it's been a little more visible to the public," he said.

As expected, Winamp's source code has been publicly released on GitHub. The Winamp for Windows project, as it's officially called by Llama Group, will receive a few updates per year, adding new features and ensuring proper security practices. Just don't get your hopes up about creating alternative projects from this "freely" available code.

Llama Group is looking to the GitHub community for help in developing new capabilities and maintaining (or even modernizing) a codebase that dates back several decades. Originally introduced in 1997, Winamp has long been praised for its flexibility and broad compatibility with various audio formats.

[...] Winamp's source code is now freely available, but the license it was released under has sparked controversy. The Winamp Collaborative License imposes significant restrictions on what people can do with the code, including a ban on releasing modified third-party modified versions. The license explicitly states that no public forks are permitted, and only the maintainers of the official repository are allowed to release the software or any new (approved) modifications.

Llama Group appears eager to benefit from community contributions to Winamp, but the software itself cannot be repurposed to create something new. Despite the legal threat, developers are undeterred, with hundreds of "unofficial" forks of Winamp's source code already surfacing online. As time goes on, this trend is only expected to grow.

Legal concerns aside, it seems clear that Llama Group no longer wants the full responsibility of maintaining the still-popular PC media player. The company has shifted its focus to different business ventures, including cloud-based products that leverage the "Winamp" brand to capitalize on music creators and streaming services.

A six-year investigation into the vast Thwaites glacier in Antarctica has concluded with a grim outlook on its future.

Often dubbed the “doomsday glacier”, this huge mass of ice is comparable in size to Britain or Florida and its collapse alone would raise sea levels by 65 centimetres. Worse still, this is expected to trigger a more widespread loss of the ice sheet covering West Antarctica, causing a calamitous sea level rise of 3.3 metres and threatening cities like New York, Kolkata and Shanghai.

It is an extremely remote and difficult area to get to, but the International Thwaites Glacier Collaboration (ITGC), a joint UK-US research programme, has managed to deploy 100 scientists there over the past six years, using planes, ships and underwater robots to study the dynamics of this ice in detail.  “It was a tremendous challenge, and yet we really learned a lot,” says Ted Scambos at University of Colorado Boulder.

These discoveries include the fact that Thwaites glacier is particularly vulnerable, as it rests on a bed of rock that is well below sea level and is being melted from the underside by warmer seawater. What’s more, the bedrock slopes downwards towards the interior of the ice sheet, so, as the glacier retreats, even more ice is exposed to warm seawater, threatening to accelerate the collapse.

[...] “It’s not going to instantaneously lead to a catastrophic retreat in the next year or the year after, but, at the same time, we are very sure that Thwaites is going to continue to retreat, and ultimately the retreat is going to accelerate,” says Rob Larter at the British Antarctic Survey, another member of the team. “We can’t put an exact time frame on that.”

Ultimately, however, the ITCG researchers think that, by the end of the 23^rd century, Thwaites glacier and much of the West Antarctic ice sheet might be lost.
