☕️ Scientifiques et universitaires se mobilisent contre l’extrême-droite

La communauté scientifique se mobilise pour ces élections législatives anticipées. La Société informatique de France (SIF) a publié une tribune rappelant les incohérences de l’extrême droite avec la démarche scientifique ainsi qu’avec « plusieurs des principes édictés par la « Déclaration universelle des droits de l’Homme et du citoyen » ».

Cette société savante, avec 500 adhérents physiques ainsi qu’une centaine de laboratoires membres à travers la France, ajoute que « l’accumulation des savoirs au profit de l’humanité ne peut prospérer que via une coopération mondiale, ouverte, et garantie par une liberté académique totale ». Elle appelle « avec la plus vive énergie à faire barrage à l’extrême-droite pour que notre pays demeure celui des Lumières, de la rationalité, de la liberté, de l’égalité et de la fraternité ».

L’association « Scientifiques en rébellion » appelle, elle, à « la mobilisation contre l’extrême droite ». Dans cette tribune signée par 2 500 scientifiques, dont les chercheurs en informatique Claire Mathieu et Jean-Christophe Soulié et les climatologues Valérie Masson-Delmotte et Christophe Cassou, appellent à lutter contre le Rassemblement national.

Le texte affirme que « l’accès au pouvoir de l’extrême droite fait non seulement peser des risques graves sur la recherche et l’enseignement, sur la place accordée aux faits scientifiques dans le débat public, mais elle menace surtout le modèle même de société auquel nous aspirons : une société démocratique où les décisions émergent de débats collectifs, ouverts, libres, respectueux et bien sûr informés ». Ils ajoutent que le « NFP n’est pas une menace pour la République ».

D’un côté plus institutionnel, le congrès de l’Université de Strasbourg a voté, explique le journal Les Dernières nouvelles d’Alsace, une motion qui s’oppose « à la mise en danger des valeurs de l’université, héritière de l’humanisme ».

Le texte affirme que « l’extrême droite est porteuse d’une idéologie qui s’attaque à cette liberté de pensée, qui veut contrôler à la fois la capacité des universitaires et des étudiantes et étudiants à s’exprimer et les sujets qu’ils et elles peuvent aborder, qui veut contrôler nos établissements pour l’accueil de talents et d’idées venant d’étudiants et étudiantes comme de chercheuses et de chercheurs étrangers. L’extrême droite veut aussi restreindre le nombre d’emplois publics, ce qui aura des effets délétères sur les missions de service public de l’enseignement supérieur et de la recherche ».

Si d’autres associations ou personnalités du secteur des sciences ou du numérique expriment leurs opinions, nous les relaierons bien évidemment. N’hésitez pas à nous les signaler.

☕️ La CNIL et la CPPA, son équivalente californienne, vont travailler de concert

Ashkan Soltani, directeur exécutif de l'Agence californienne de protection de la vie privée (CPPA) et Marie-Laure Denis, présidente de la CNIL

Ashkan Soltani, directeur exécutif de l’Agence californienne de protection de la vie privée (CPPA) et Marie-Laure Denis, présidente de la CNIL, viennent de signer, à Paris, une « déclaration de coopération » qui prévoit, notamment :

  • la conduite de recherches conjointes liées aux nouvelles technologies et aux questions de protection des données ;
  • le partage de bonnes pratiques et d’expériences, y compris dans le cadre de leurs enquêtes ;
  • l’organisation d’ateliers de travail et de réunions périodiques.

L’objectif est de « tisser des liens institutionnels et humains entre la CPPA et la CNIL au travers de projets communs », afin de renforcer leur compréhension des nouvelles technologies et de « relever ensemble les défis posés par la protection des données personnelles dans un contexte d’accroissement des usages numériques ».

La CNIL souligne que la CPPA (pour California Privacy Protection Agency), créée en 2020, est le « premier organisme de réglementation dédié à la protection de la vie privée aux États-Unis ».

La CPPA précise de son côté que la loi californienne sur la protection de la vie privée des consommateurs (CCPA, pour California Consumer Privacy Act) est « la première loi complète sur la protection de la vie privée des consommateurs aux États-Unis », et qu’« elle confère aux consommateurs californiens plusieurs droits, notamment le droit d’accéder à leurs informations personnelles, de les supprimer et de mettre fin à leur vente ».

Figure de proue de la défense de la « privacy » aux États-Unis, Ashkan Soltani s’était fait connaître pour ses travaux au sujet du tracking publicitaire, des révélations Snowden, avant d’être nommé « Chief Technologist » à la Federal Trade Commission (FTC) en 2015, puis directeur exécutif de la CPPA en 2021.

De plus en plus de joueurs PC, sur Steam, avec une manette

Il y a un peu moins d'un an, Valve faisait de gros efforts pour la prise en charge des manettes DualSense sur Steam, avec une meilleure visibilité de son éventuelle prise en charge sur les fiches des jeux. A ce moment, environ 27 % des joueurs Steam avec une manette étaient équipés Sony, et les choses n'ont guère évolué depuis : la dernière étude Steam donné 26 %, contre 59 % avec une manette Xbox. Mais le plus important reste finalement la proportion de joueurs avec une manette, qui est passée de 5 % en 2018 à 15 % pour cette année. […]

SpaceX Scores $843 Million NASA Contract To De-Orbit ISS In 2030

In a contract worth as much as $843 million, NASA announced today SpaceX has been selected to develop a vehicle that will de-orbit the International Space Station in 2030. "As the agency transitions to commercially owned space destinations closer to home, it is crucial to prepare for the safe and responsible deorbit of the International Space Station in a controlled manner after the end of its operational life in 2030," the U.S. space agency said in a statement. TechCrunch reports: Few details about the U.S. Deorbit Vehicle, as NASA calls the craft, have been released so far. However, NASA clarified that the vehicle will be different from SpaceX's Dragon capsule, which delivers cargo and crew to the station, and other vehicles that perform services for the agency. Unlike these vehicles, which are built and operated by SpaceX, NASA will take ownership of the U.S. Deorbit Vehicle post-development and operate it throughout its mission. Both the vehicle and the ISS will destructively break up as they reenter the atmosphere, and one of the big tasks ahead for SpaceX is to ensure that the station reenters in a way that endangers no populated areas. The launch contract for the U.S. Deorbit Vehicle will be announced separately. NASA and its partners had been evaluating using a Russian Roscosmos Progress spacecraft to conduct the de-orbit mission, but studies indicated that a new spacecraft was needed for the de-orbit maneuver. The station's safe demise is a responsibility shared by the five space agencies that operate on the ISS -- NASA, the Canadian Space Agency, European Space Agency, Japan Aerospace Exploration Agency, and State Space Corporation Roscosmos -- but it is unclear whether this contract amount is being paid out by all countries.

World's First Carbon Tax On Livestock Will Cost Farmers $100 Per Cow

An anonymous reader quotes a report from CNN: Dairy farmers in Denmark face having to pay an annual tax of 672 krone ($96) per cow for the planet-heating emissions they generate. The country's coalition government agreed this week to introduce the world's first carbon emissions tax on agriculture. It will mean new levies on livestock starting in 2030. Denmark is a major dairy and pork exporter, and agriculture is the country's biggest source of emissions. The coalition agreement -- which also entails investing 40 billion krone ($3.7 billion) in measures such as reforestation and establishing wetlands -- is aimed at helping the country meet its climate goals. "With today's agreement, we are investing billions in the biggest transformation of the Danish landscape in recent times," Foreign Minister Lars Lokke Rasmussen said in a statement Tuesday. "At the same time, we will be the first country in the world with a (carbon) tax on agriculture." The Danish dairy industry broadly welcomed the agreement and its goals, but it has angered some farmers. [...] The tax, expected to be approved by Denmark's parliament later this year, will amount to 300 krone ($43) per tonne (1.1 ton) of CO2-equivalent emissions from livestock from 2030, rising to 750 krone ($107) in 2035. A 60% tax break will apply, meaning that farmers will effectively be charged 120 krone ($17) per tonne of livestock emissions per year from 2030, rising to 300 krone ($43) in 2035. On average, Danish dairy cows, which account for much of the cattle population, emit 5.6 tons of CO2-equivalent per year, according to Concito, a green think tank in Denmark. Using the lower tax rate of 120 krone results in a charge of 672 krone per cow, or $96. With the tax break in place, that levy will rise to 1,680 krone per cow in 2035 ($241). In the first two years, the proceeds from the tax will be used to support the agricultural industry's green transition and then reassessed. "The whole purpose of the tax is to get the sector to look for solutions to reduce emissions," Concito's chief economist Torsten Hasforth told CNN. For example, farmers could change the feed they use.

Microsoft Blamed For Million-Plus Patient Record Theft At US Hospital Giant

Brandon Vigliarolo reports via The Register: American healthcare provider Geisinger fears highly personal data on more than a million of its patients has been stolen -- and claimed a former employee at a Microsoft subsidiary is the likely culprit. Geisinger on Monday announced the results of a probe into a November computer security breach, placing the blame on Microsoft-owned Nuance Communications for not cutting off one of its employees' access to corporate files after that person was fired. The Pennsylvania-based healthcare giant uses Nuance as an IT provider. We're told that after the Microsoft-owned entity terminated one of its workers, that staffer two days later may have accessed and taken copies of sensitive records on a huge number of Geisinger patients -- for reasons as yet unknown. Geisinger -- which says it operates 13 hospitals and has more than 600,000 members -- said it discovered the improper access on November 29, informed Nuance, and the IT supplier immediately cut off the former employee from the healthcare group's data before involving police. "Because it could have impeded their investigation, law enforcement investigators asked Nuance to delay notifying patients of this incident until now," Geisinger claimed, explaining why only now this is coming to light. "The former Nuance employee has been arrested and is facing federal charges." It's not immediately clear if or what charges have been laid -- we've asked Geisinger for details. Speech recognition firm Nuance performed its own probe, according to Geisinger, and determined that the former employee may have stolen information on a million-plus people. That info would include birth dates, addresses, hospital admission and discharge records, demographic information, and other medical data. The ex-employee didn't swipe insurance or other financial information, the multi-billion-dollar healthcare group stated. "We continue to work closely with the authorities on this investigation, and while I am grateful that the perpetrator was caught and is now facing federal charges," Geisinger chief privacy officer Jonathan Friesen alleged, adding: "I am sorry that this happened."

Apple Pauses Work On Planned North Carolina Campus

In 2021, Apple announced plans for a new $1 billion campus in North Carolina, set to include a new engineering and research center and support up to 3,000 employees. According to Lauren Ohnesorge of Triangle Business Journal (paywalled), Apple remains committed to the project, but the timeline has been delayed by four years. MacRumors reports: A limited amount of progress on the campus has been made since the announcement, and Apple has not provided updates on construction until now. Apple told Triangle Business Journal that it has paused work on the campus, and it is working with North Carolina Governor Roy Cooper and the North Carolina Department of Commerce to extend the project's timeline by four years. Apple last year filed development plans for the first phase of construction, but the specific timeline for the project has never been clear. Apple's plans for Research Triangle Park include six buildings and a parking garage totaling 700,000 square feet of office space, 190,000 square feet of accessory space, and close to 3,000 parking spaces spanning 41 acres. Apple owns 281 acres of land in the area where it plans to build its campus, so there could ultimately be several phases of construction. As it prepares to build the NC research center, Apple is leasing more than 200,000 square feet of office space in Cary, North Carolina. In a statement, Apple said it is still committed to the project: "Apple has been operating in North Carolina for over two decades. And we're deeply committed to growing our teams here. In the last three years, we've added more than 600 people to our team in Raleigh, and we're looking forward to developing our new campus in the coming years."

Crypto Industry Super PAC Is 33-2 In Primaries, With $100 Million For House and Senate Races

A super PAC called Fairshake, funded primarily by top cryptocurrency companies, achieved several wins in congressional primaries and plans to spend over $100 million to support pro-crypto candidates in the general elections. CNBC reports: Fairshake and its two affiliated political action committees, one for Republicans, one for Democrats, quietly racked up half a dozen other wins Tuesday as the candidates they backed glided to victory, although none of the races were competitive. They included Rep. John Curtis, who won the Republican nomination for Utah's open Senate seat. Created last year as part of a joint effort between more than a dozen crypto firms, Fairshake PAC has emerged as one of the top-spending PACs in the 2024 election cycle. Fairshake and its two affiliated PACs have put more than $37 million so far into advertisements in primary races, according to AdImpact. Despite a broad mission to defend the entire $2.2 trillion crypto market, Fairshake is funded by a very small set of donors. Of the $160 million in total contributions Fairshake has raised since it was founded, around $155 million -- or 94% -- can be traced back to just four companies: Ripple, Andreesen Horowitz, Coinbase and Jump Crypto. But it's not just money that the crypto industry plans to deploy this fall. The nonprofit Stand With Crypto says it has collected more than 1.1 million email addresses of crypto "advocates" it hopes to engage all the way to the ballot box. The strength of the crypto groups is getting noticed on Capitol Hill, especially among lawmakers who are facing tough elections in 2025, where a few thousand voters, or a hefty donation, could make a difference in not only a race but in which party controls each chamber. [...] In the coming months, the group doesn't plan to spend on the presidential race, but rather the House and Senate, according to a Fairshake spokesperson. Both of those chambers are in play for 2025. Fairshake has yet to start spending in the general election cycle, but several officials in the industry said they are keeping an eye on states such as Ohio and Montana, where Democratic incumbents who are bearish on crypto face challengers who have embraced the technology. [...] Ads funded by Fairshake deliver messages that are typically less about a candidates' support for or opposition to crypto, and more about broader issues that resound with voters, such as fairness and integrity.

A Russian Propaganda Network Is Promoting an AI-Manipulated Biden Video

An anonymous reader quotes a report from Wired: In recent weeks, as so-called cheap fake video clips suggesting President Joe Biden is unfit for office have gone viral on social media, a Kremlin-affiliated disinformation network has been promoting a parody music video featuring Biden wearing a diaper and being pushed around in a wheelchair. The video is called "Bye, Bye Biden" and has been viewed more than 5 million times on X since it was first promoted in the middle of May. It depicts Biden as senile, wearing a hearing aid, and taking a lot of medication. It also shows him giving money to a character who seems to represent illegal migrants while denying money to US citizens until they change their costume to mimic the Ukrainian flag. Another scene shows Biden opening the front door of a family home that features a Confederate flag on the wall and allowing migrants to come in and take over. Finally, the video contains references to stolen election conspiracies pushed by former president Donald Trump. The video was created by Little Bug, a group that mimics the style of Little Big, a real Russian band that fled the country in 2022 following Russia's invasion of Ukraine. The video features several Moscow-based actors -- who spoke with Russian media outlet Agency.Media -- but also appears to use artificial intelligence technology to make the actors resemble Biden and Trump, as well as Ilya Prusikin, the lead singer of Little Big. "Biden and Trump appear to be the same actor, with deepfake video-editing changing his facial features until he resembles Biden in one case and Trump in the other case," says Alex Fink, an AI and machine-vision expert who analyzed the video for WIRED. "The editing is inconsistent, so you can see that in some cases he resembles Biden more and in others less. The facial features keep changing." An analysis by True Media, a nonprofit that was founded to tackle the spread of election-related deepfakes, found with 100 percent confidence that there was AI-generated audio used in the video. It also assessed with 78 percent confidence that some AI technology was used to manipulate the faces of the actors. Fink says the obvious nature of the deepfake technology on display here suggests that the video was created in a rush, using a small number of iterations of a generative adversarial network in order to create the characters of Biden and Trump. It is unclear who is behind the video, but "Bye, Bye Biden" has been promoted by the Kremlin-aligned network known as Doppelganger. The campaign posted tens of thousands of times on X and was uncovered by Antibot4Navalny, an anonymous collective of Russian researchers who have been tracking Doppelganger's activity for the past six months. The campaign first began on May 21, and there have been almost 4,000 posts on X promoting the video in 13 languages that were promoted by a network of almost 25,000 accounts. The Antibot4Navalny researchers concluded that the posts were written with the help of generative AI technology. The video has been shared 6.5 million times on X and has been viewed almost 5 million times.

Microsoft's Canceled Xbox Cloud Console Gets Detailed In New Patent

Microsoft's canceled Xbox cloud console, codenamed Keystone, has been detailed in a new patent spotted by Windows Central's Zac Bowden. From the report: Back in 2021, Microsoft announced that it was working on a dedicated streaming device for Xbox Game Pass. That device was later revealed to be codenamed Keystone, which took the form of a streaming box that would sit under your TV, cost a fraction of the price of a normal Xbox, and enable the ability to play Xbox games via the cloud. Unfortunately, it appears Microsoft has since scrapped plans to ship Xbox Keystone due to an inability to bring the price down to a level where it made sense for customers. Xbox CEO Phil Spencer is on record saying the device should have costed around $99 or $129, but the company was unable to achieve this. Thanks to a patent discovered by Windows Central, we can finally take a closer look at the box Microsoft had conjured up internally. First up, the patent reveals that the console took the form of an even square with a circle shape on top, similar to the black circular vent on an Xbox Series S. The front of the box had the Xbox power button, and a USB-A port. Around the back, there were three additional ports; HDMI, ethernet, and power. On the right side of the console there was appears to be an Xbox controller pairing button, and the underside featured a circular "Hello from Seattle" plate that the console sat on, similar to the Xbox Series X. This patent was filed in June 2022, which was around the time when the first details of Xbox Keystone were being revealed.

Frore Unveils Waterproof AirJet Mini Sport for Smartphones

Over the past couple of years, Frore Systems has demonstrated several ways that its AirJet solid-state active cooling systems can be used to improve cooling in fanless devices like laptops, tablets, SSDs, and edge computing devices. But there are a subset of those applications that need their cooling options to also be waterproof, and Frore is looking to address those as well. To that end, this week Frore introduced its AirJet Mini Sport, a waterproof, IP68-rated solid-state cooling device that is aimed at use in smartphones and action cameras.

Introduced at MWC Shanghai to attract attention of China-based handset vendors, edge and industrial computing devices, and action cameras, the AirJet Mini Sport is an enhanced version of Frore's AirJet Mini Slim. This version has been fully waterproofed, offering IP68-level protection that allows it to work while being submerged in over 1.5 meters of water for up to 30 minutes. Internally, the AirJet Mini Sport can effectively dissipate 5.25 Watts of heat by generating 1750 Pascals of back pressure, while consuming 1 Watt of energy itself.

Elsewhere, Frore claims that the AirJet Mini Sport can be used to provide 2.5 Watts of cooling capacity to smartphones. Which, although not enough to cover the complete power consumption/heat dissipation of a high-end SoC, would have a significant impact on both burst and steady-state performance by allowing those chips to run at peak clocks and power for longer periods of time.

To ensure consistent performance of Frore's AirJet Mini Sport in diverse environments, the cooling device includes features such as dust resistance and self-cleaning. In addition, just like AirJet Mini Slim, the Sport-badged version its own thermal sensor to control its own operation and maintain optimal performance. As a result, Frore claims that smartphones and action cameras with the AirJet Mini Sport can achieve up to 80% better performance.

"We are excited to announce the waterproof AirJet Mini Sport," said Dr. Seshu Madhavapeddy, founder and CEO of Frore Systems. "Consumers demand increased performance in compact devices they can use anywhere, on land or in water. AirJet unleashes device performance, now enabling users to do more with their IP68 dustproof and waterproof devices."

Australian Bank Spots Scams via How Users Hold Their Phones

National Australia Bank seems to think that monitoring the angle customers hold their phones will offer extra protection against scammers. "Speaking during the Australian Banking Association Conference in Melbourne Wednesday (June 26), CEO Andrew Irvine said the lender introduced more 'friction' to payments processes and new predictive protection tools to spot scammers," reports PYMNTS.com, citing a (paywalled) Bloomberg report. From the report: "We've added tooling that looks at biometrics and the way you actually interact with your devices and how you think about keystrokes," said Irvine, per the report. "If these things are different to how you've used your phone in the past, our intelligence will kick in." Irvine, who called fraudsters the "scourge of our times," also noted that Australia is one of the few countries where bank fraud has declined, the report said. Still, he said that as scammers have embraced new technology like artificial intelligence, banks have had to shift from making payments fast and simple to adding more steps to protect against fraudulent transactions, per the report. "These threat actors go where the money is," Irvine said, according to the report. "You want to be the best alarm system in the street and right now Australia's leading the way."

Toys 'R' Us Riles Critics With 'First-Ever' AI-Generated Commercial Using Sora

An anonymous reader quotes a report from Ars Technica: On Monday, Toys "R" Us announced that it had partnered with an ad agency called Native Foreign to create what it calls "the first-ever brand film using OpenAI's new text-to-video tool, Sora." OpenAI debuted Sora in February, but the video synthesis tool has not yet become available to the public. The brand film tells the story of Toys "R" Us founder Charles Lazarus using AI-generated video clips. "We are thrilled to partner with Native Foreign to push the boundaries of Sora, a groundbreaking new technology from OpenAI that's gaining global attention," wrote Toys "R" Us on its website. "Sora can create up to one-minute-long videos featuring realistic scenes and multiple characters, all generated from text instruction. Imagine the excitement of creating a young Charles Lazarus, the founder of Toys "R" Us, and envisioning his dreams for our iconic brand and beloved mascot Geoffrey the Giraffe in the early 1930s." The company says that The Origin of Toys "R" Us commercial was co-produced by Toys "R" Us Studios President Kim Miller Olko as executive producer and Native Foreign's Nik Kleverov as director. "Charles Lazarus was a visionary ahead of his time, and we wanted to honor his legacy with a spot using the most cutting-edge technology available," Miller Olko said in a statement. In the video, we see a child version of Lazarus, presumably generated using Sora, falling asleep and having a dream that he is flying through a land of toys. Along the way, he meets Geoffery, the store's mascot, who hands the child a small red car. Many of the scenes retain obvious hallmarks of AI-generated imagery, such as unnatural movement, strange visual artifacts, and the irregular shape of eyeglasses. [...] Although the Toys "R" Us video uses key visual elements from Sora, it still required quite a bit of human post-production work to put it together. Sora eliminated the need for actors and cameras, but creating successful generations and piecing together the rest still took human scriptwriters and VFX artists to fill in the AI model's shortcomings. "The brand film was almost entirely created with Sora, with some corrective VFX and an original music score composed by Aaron Marsh of famed indie rock band Copeland," wrote Toys "R" Us in a press release. Comedy writer Mike Drucker wrapped up several of these criticisms into one post, writing: "Love this commercial is like, 'Toys R Us started with the dream of a little boy who wanted to share his imagination with the world. And to show how, we fired our artists and dried Lake Superior using a server farm to generate what that would look like in Stephen King's nightmares.'" Other critical comments were more frank. Filmmaker Joe Russo posted: "TOYS 'R US released an AI commercial and it fucking sucks."

Exam Submissions By AI Found To Earn Higher Grades Than Real-Life Students

Exam submissions generated by AI can not only evade detection but also earn higher grades than those submitted by university students, a real-world test has shown. From a report: The findings come as concerns mount about students submitting AI-generated work as their own, with questions being raised about the academic integrity of universities and other higher education institutions. It also shows even experienced markers could struggle to spot answers generated by AI, the University of Reading academics said. Peter Scarfe, an associate professor at Reading's School of Psychology and Clinical Language Sciences said the findings should serve as a "wake-up call" for educational institutions as AI tools such as ChatGPT become more advanced and widespread. He said: "The data in our study shows it is very difficult to detect AI-generated answers. There has been quite a lot of talk about the use of so-called AI detectors, which are also another form of AI but (the scope here) is limited." For the study, published in the journal Plos One, Prof Scarfe and his team generated answers to exam questions using GPT-4 and submitted these on behalf of 33 fake students. Exam markers at Reading's School of Psychology and Clinical Language Sciences were unaware of the study. Answers submitted for many undergraduate psychology modules went undetected in 94% of cases and, on average, got higher grades than real student submissions, Prof Scarfe said.
