Comme l’a repéré David Libeau, La préfecture de Paris a publié (pdf) lundi 6 mai un arrêté autorisant la RATP à expérimenter dans les stations Nanterre Préfecture et La Défense Grande Arche son dispositif de vidéosurveillance algorithmique pendant une semaine, du mardi 7 mai 2024 à 08h00 au mardi 14 mai 2024 à 08h00. L’arrêté est donc publié seulement 24h avant le début des opérations.

La RATP veut utiliser le concert de Taylor Swift qui aura lieu à la salle du Paris La Défense Arena (les 9, 10, 11 et 12 mai) comme moment de test grandeur nature pour son outil de traitement algorithmique dénommé « Cityvision » et développé par la société Wintic.

Sur sa page de politique générale de confidentialité, l’entreprise de transport indiquait que la durée d’expérimentation serait du 09 mai au 12 mai (les jours des concerts de l’artiste mais aussi « intégrant une phase de conception (sans usage opérationnel) du 29/04/2024 au 11/05/2024 ».

La préfecture lui a donc autorisé une plage d’expérimentation plus importante que prévu.

En février, JeGX publiait la version 2.0 de son application pour analyser les performances et la stabilité de votre GPU (avec un stress intense). La version 2.3 a été mise en ligne hier.

Les notes de version parlent de petits changements comme l’ajout de la vitesse du ventilateur dans la section GPU monitoring. Il y a bien évidemment aussi les traditionnelles corrections de bugs.

Mais on retrouve surtout la prise en charge d’un nouveau système : Raspberry Pi OS (64-bit, arm64/aarch64). Cette version a été compilée sur Debian 11 avec GLIC 2.31.

JeGX en profite pour donner deux résultats : « Sur le Raspberry Pi 4, FurMark 2 fonctionne à 1 FPS (résolution : 1024×640). Le nouveau matériel du Raspberry Pi 5 est beaucoup plus rapide : on atteint 4 FPS (toujours à 1024×640) ».

« J’ai essayé de supprimer les dépendances de Raspberry Pi et j’espère que cette version fonctionnera sur d’autres plates-formes arm64/aarch64 », ajoute-t-il.

Il était attendu, et il n'a visiblement pas déçu les nombreux joueurs qui se sont rués dessus : Hades II est désormais disponible en accès anticipé sur Steam. Et forcément se pose la question du choix de l'accès anticipé alors que Supergiant Games a acquis une belle expérience avec le premier opus, mais les choses sont simples pour le développeur : modifier le jeu en fonction des retours afin que le jeu soit parfait ; tous les détails à son sujet sont ici. La version définitive n'est ainsi pas attendue avant le début de l'année 2025, tandis que la vraie fin du jeu ne sera proposée qu'une fois le jeu terminé. A chacun de faire son choix donc, mais Hades II a déjà ses fans. A juste titre de notre point de vue. […]

Boeing Starliner's First Crewed Mission Scrubbed

"Out of an abundance of caution," Boeing says its historic Starliner launch has been postponed, citing an issue with the oxygen relief valve on the Atlas V rocket's upper stage. It was expected to launch tonight at 10:34 p.m. ET. TechCrunch reports: There are backup launch opportunities on May 7, 10 and 11. After years of delays and over $1 billion in cost overruns, the mission is set to be Boeing's first attempt to transport astronauts to the International Space Station. Once the issue is resolved with the upper stage, the United Launch Alliance Atlas V will carry the CST-100 Starliner capsule to orbit along with the two onboard astronauts -- Butch Wilmore and Sunny Williams -- from Florida's Cape Canaveral at 10:34 PM local time Monday evening. The mission also marks the first time ULA's Atlas will carry crew. The rocket boasts a success rate of 100% across 99 missions. (ULA is a joint venture of Boeing and Lockheed Martin.) The astronauts would now dock at the station at the earliest on Thursday, where they would remain for at least eight days. The two astronauts will return to Earth in the capsule no earlier than May 16. If all goes to plan, Boeing will be able to finally certify its Starliner for human transportation and begin fulfilling the terms of its $4.2 billion NASA astronaut taxi contract. That contract, under the agency's Commercial Crew Program, was awarded in 2014. Elon Musk's SpaceX was also granted a contract under that program, for its Crew Dragon capsule, and has been transporting astronauts to and from the ISS since 2020.

Boeing Starliner

On pourrait presque croire à un gag. Cinq ans après le premier vol non habité, Boeing devait envoyer cette nuit ses premiers astronautes dans l’espace, direction la Station spatiale internationale. La tentative a été annulée « en raison d’un problème de soupape sur l’étage supérieur du lanceur », explique le constructeur.

La décision a été prise par le fabricant de la fusée : « United Launch Alliance (ULA), avec l’accord de Boeing et de la NASA, a annulé le lancement un peu plus de deux heures avant l’heure de décollage initialement prévue pour l’essai en vol de l’équipage CST-100 Starliner ». Les astronautes de la NASA Butch Wilmore et Suni Williams sont sortis de la capsule et sont retournés dans leur quartier.

Les analyses sont en cours pour « bien comprendre le problème et déterminer les mesures correctives ». TechCrunch rappelle que des dates de secours sont prévues les 7, 10 et 11 mai, mais encore faut-il que le souci soit identifié et corrigé.

Pour la NASA, la date de lancement ne sera pas avant le 10 mai : ” Ce délai permet aux équipes de compléter l’analyse des données sur une vanne de régulation de pression du réservoir d’oxygène liquide de l’étage supérieur Centaur de la fusée Atlas V, et déterminer s’il est nécessaire de la remplacer ”

Apple's iPhone Spyware Problem Is Getting Worse

✇Slashdot
Par : BeauHD
7 mai 2024 à 03:30
An anonymous reader quotes a report from Wired: In April, Apple sent notifications to iPhone users in 92 countries, warning them they'd been targeted with spyware. "Apple detected that you are being targeted by a mercenary spyware attack that is trying to remotely compromise the iPhone associated with your Apple ID," the notification reads. Users quickly took to social media sites including X, trying to work out what the notification meant. Many of those targeted were based inIndia, but others in Europe also reported receiving Apple's warning. Weeks later, little is still known about the latest iPhone attacks. Former smartphone giant Blackberry, now a security firm, has released research indicating they are linked to a Chinese spyware campaign dubbed "LightSpy," but Apple spokesperson Shane Bauer says this is inaccurate. While Apple says the latest spyware notifications aren't linked to LightSpy, the spyware remains a growing threat, particularly to people who may be targeted in Southern Asia, according to Blackberry's researchers. Described as a "sophisticated iOS implant," LightSpy first emerged targeting Hong Kong protesters in 2020. However, the latest iteration is much more capable than the first. "It is a fully-featured modular surveillance toolset that primarily focuses on exfiltrating victims' private information, including hyper-specific location data and sound recording during voice over IP calls," the researchers wrote. April's warnings were not the first time Apple has issued notifications of this kind. The iPhone maker has sent out alerts to people in over 150 countries since 2021 as spyware continues to target high-profile figures across the globe. Spyware can be weaponized by nation-state adversaries -- but this is relatively rare and expensive. Its deployment is typically highly targeted against a very specific group of people, including journalists, political dissidents, government workers, and businesses in certain sectors. "Such attacks are vastly more complex than regular cybercriminal activity and consumer malware, as mercenary spyware attackers apply exceptional resources to target a very small number of specific individuals and their devices," Apple wrote in an advisory in April. "Mercenary spyware attacks cost millions of dollars and often have a short shelf life, making them much harder to detect and prevent. The vast majority of users will never be targeted by such attacks." Plus, Apple says its Lockdown Mode feature can successfully protect against attacks. "As we have said before, we are not aware of anyone using Lockdown Mode being successfully attacked with mercenary spyware," Bauer says. Still, for those who are targeted and caught unaware, spyware is extremely dangerous. There are a number of ways to protect yourself against spyware and zero-click exploits in particular: 1. Regularly Update Devices: Keep your devices updated to the latest software to protect against known vulnerabilities. 2. Restart Devices Daily: Regularly restarting your device can help disrupt persistent spyware infections by forcing attackers to reinfect the device, potentially increasing their chances of detection. 3. Disable Vulnerable Features: Consider disabling features prone to exploits, such as iMessage and FaceTime, especially if you suspect you're a target for spyware. 4. Use Multifactor Authentication and Secure Sources: Employ multifactor authentication and only install apps from verified sources to prevent unauthorized access and downloads. 5. Monitor for Indicators: Be vigilant for signs of infection such as battery drain, unexpected shutdowns, and high data usage, though these may not always be present with more sophisticated spyware. 6. Seek Professional Help: If you suspect a spyware infection, consider professional assistance or helplines like Access Now's Digital Security Helpline for guidance on removal. 7. Utilize Advanced Security Features: Activate security features like Apple's Lockdown Mode, which limits device functionality to reduce vulnerabilities, thus safeguarding against infections.

Swedish energy company Stockholm Exergi and Microsoft have announced a 10-year deal that will provide the tech giant with more than 3.3 million tons of carbon removal certificates through bioenergy with carbon capture and storage. While the value of the deal was not disclosed, it stands as the largest of its kind globally. Carbon Herald reports: Scheduled to commence in 2028 and span a decade, the agreement underscores a pivotal moment in combatting climate change. Anders Egelrud, CEO of Stockholm Exergi, lauded the deal as a "huge step" for the company and its BECCS project, emphasizing its profound implications for climate action. "I believe the agreement will inspire corporations with ambitious climate objectives, and we target to announce more deals with other pioneering companies over the coming months," he said. Recognizing the imperative of permanent carbon removals in limiting global warming to 1.5C or below, the deal aligns with Microsoft's ambitious goal of becoming carbon negative by 2030. "Leveraging existing biomass power plants is a crucial first step to building worldwide carbon removal capacity," Brian Marrs, Microsoft's Senior Director of Energy & Carbon Removal, said, highlighting the importance of sustainable biomass sourcing for BECCS projects, as is the case with Stockholm Exergi. The partners will adhere to stringent quality standards, ensuring transparent reporting and adherence to sustainability criteria. The BECCS facility, once operational, will remove up to 800,000 tons of carbon dioxide (CO2) annually, contributing significantly to atmospheric carbon reduction. With environmental permits secured and construction set to commence in 2025, Stockholm Exergi plans to reach the final investment decision by the end of the year.

Novel Attack Against Virtually All VPN Apps Neuters Their Entire Purpose

✇Slashdot
Par : BeauHD
7 mai 2024 à 01:41
Researchers have discovered a new attack that can force VPN applications to route traffic outside the encrypted tunnel, thereby exposing the user's traffic to potential snooping or manipulation. This vulnerability, named TunnelVision, is found in almost all VPNs on non-Linux and non-Android systems. It's believe that the vulnerability "may have been possible since 2002 and may already have been discovered and used in the wild since then," reports Ars Technica. From the report: The effect of TunnelVision is "the victim's traffic is now decloaked and being routed through the attacker directly," a video demonstration explained. "The attacker can read, drop or modify the leaked traffic and the victim maintains their connection to both the VPN and the Internet." The attack works by manipulating the DHCP server that allocates IP addresses to devices trying to connect to the local network. A setting known as option 121 allows the DHCP server to override default routing rules that send VPN traffic through a local IP address that initiates the encrypted tunnel. By using option 121 to route VPN traffic through the DHCP server, the attack diverts the data to the DHCP server itself. [...] The attack can most effectively be carried out by a person who has administrative control over the network the target is connecting to. In that scenario, the attacker configures the DHCP server to use option 121. It's also possible for people who can connect to the network as an unprivileged user to perform the attack by setting up their own rogue DHCP server. The attack allows some or all traffic to be routed through the unencrypted tunnel. In either case, the VPN application will report that all data is being sent through the protected connection. Any traffic that's diverted away from this tunnel will not be encrypted by the VPN and the Internet IP address viewable by the remote user will belong to the network the VPN user is connected to, rather than one designated by the VPN app. Interestingly, Android is the only operating system that fully immunizes VPN apps from the attack because it doesn't implement option 121. For all other OSes, there are no complete fixes. When apps run on Linux there's a setting that minimizes the effects, but even then TunnelVision can be used to exploit a side channel that can be used to de-anonymize destination traffic and perform targeted denial-of-service attacks. Network firewalls can also be configured to deny inbound and outbound traffic to and from the physical interface. This remedy is problematic for two reasons: (1) a VPN user connecting to an untrusted network has no ability to control the firewall and (2) it opens the same side channel present with the Linux mitigation. The most effective fixes are to run the VPN inside of a virtual machine whose network adapter isn't in bridged mode or to connect the VPN to the Internet through the Wi-Fi network of a cellular device. You can learn more about the research here.

Google Fit Dev APIs Shutdown Set, Fate of Android and Wear OS Apps Go Unannounced

7 mai 2024 à 00:53
Abner Li reports via 9to5Google: Since the launch of Health Connect in 2022, Google has been winding down the Google Fit developer APIs. Earlier this week, the company fully detailed how the "Google Fit APIs have been deprecated and will be supported until June 30, 2025." Fitness and exercise apps that previously used Google Fit have until the June 2025 deadline to switch to Health Connect, with Google broadly referring to it as the "Android Health platform." Google's migration guide for developers lists what they're supposed to switch to on Android phones and Wear OS. However, there is no replacement for the Goals API that lets Google Fit users set "how many steps and heart points they want to aim for each day." Google says it will "share more details about what's next for Android Health" at I/O later this month. As of this API shutdown announcement, Google has said nothing about the Google Fit apps on Android, Wear OS, and iOS. They still work to track activity and house your full archive. [...] At this point, it's clear that Google Fit is not the future. On the Pixel Watch, Fitbit is the default, while Samsung and other Wear OS manufacturers have their own health tracking solutions. If Google were to announce a deprecation of the Fit app, having it coincide with the June 2025 developer deadline makes sense.

Pokemon Go Players Are Vandalizing Real Maps With Fake Data To Catch Rare Pokemon

✇Slashdot

7 mai 2024 à 00:02
An anonymous reader quotes a report from 404 Media: Pokemon Go players are creating a headache for members of the open source map tool OpenStreetMaps by adding fake beaches where they don't exist in hopes of more easily catching Wigletts, a Pokemon that only spawns on beaches. OpenStreetMaps is a free, open source map tool much like Google or Apple maps, but is maintained by a self-governing community of volunteers where anyone is welcome to contribute. An April 27 thread in the OpenStreetMap community forum first spotted the issue, flagging two users in Italy who began marking beaches in all sorts of locations where they don't actually exist. The OpenStreetMap user who noticed the fictitious beaches immediately connected the dots: Pokemon Go, the mega popular mobile game where players catch Pokemon and can engage in different activities depending on their geolocation, introduced different "biomes" like beach, city, forest, and mountains. Each of these have a different look, and critically, some specific Pokemon will only spawn at specific biomes. Wiglett, for example, only spawns at beaches. Some video game sites quickly noticed that Pokemon Go's beaches were appearing in real world locations like golf courses, sports fields, and other places that are not real beaches. Pokemon Go uses OpenStreetMap for its map data, and is how the game knows players are near certain points of interest. The OpenStreetMap user created a filter of OpenStreetMap that surfaced instances where "new mappers" added beaches to the map, revealing a number of clearly fake submissions. [...] It's not clear how often Pokemon Go updates the game with data from OpenStreetMaps, but in theory the people who are manipulating the data would have easier access to the beach biome the next time it does. The OpenStreetMap thread goes on to identify one repeat offender who added dozens of fake beaches. Some are near bodies of water, like lakes, rivers, or docks, and others are landlocked schools, parking lots, and random strips of land. If there was any doubt that some of these changes are being made by Pokemon Go players, the same repeat offender also marked the map with his handle, as well as a poke ball.

Jack Dorsey is no longer on the board of Bluesky, the Twitter alternative he helped start. The announcement comes shortly after Dorsey unfollowed all but three accounts on X and referred to Elon Musk's platform as "freedom technology." The Verge reports: In two posts today, Bluesky thanked Dorsey while confirming his departure and adding that it's searching for a new board member "who shares our commitment to building a social network that puts people in control of their experience." [...] Neither Bluesky nor Dorsey himself seem to have said how or why he left the board. For now, two board members remain: CEO, Jay Graeber, and Jabber / XMPP inventor Jeremie Miller. Dorsey originally backed Bluesky in 2019 as a project to develop an open-source social media standard that he wanted Twitter to move to. He later joined its board of directors when it split from Twitter in 2022.

The Rabbit R1 Could've Just Been a Mobile App

✇Slashdot
Par : BeauHD
6 mai 2024 à 22:40
The Rabbit R1 is one of the first standalone AI companion devices to hit the market, offering the ability to translate languages, identify objects in your environment, and order DoorDash, among other things. It's been in the news last week for its all around poor reviews that cite poor battery life, painfully slow responses, and missing features (sound familiar?). Now, it's been confirmed that the Rabbit R1 is powered by an Android app that can run on existing Android phones. Android Authority reports: What ended up souring a lot of people's opinions on the product was the revelation -- in an Android Authority original report -- that the R1 is basically an Android app in a box. Many consumers who believed that the product would be better suited as a mobile app felt validated after our report, but there was one stickler in it that we needed to address: how we got the R1 launcher up and running on an Android phone. See, in our preliminary report, we mentioned that the Rabbit R1's launcher app is intended to be preinstalled in the firmware and be granted several privileged, system-level permissions. While that statement is still true, we should've clarified that the R1 launcher doesn't actually need those permissions. In fact, none of the system-level permissions that the R1 launcher requests are at all necessary for the app to perform its core functionality. To prove this, we got the Rabbit R1 launcher up and running again on a stock, unrooted Android device (a Xiaomi 13T Pro), thanks to help from a team of reverse engineers including ChromMob, EmilyLShepherd, marceld505, thel3l, and uwukko. We were able to go through the entire setup process as if our device was an actual Rabbit R1. Afterwards, we were able to talk to ChatGPT, use the Vision function to identify objects, play music from Spotify, and even record voice notes. As demonstrated in our hands-on video at the top of this article, all of the existing core functionality that the Rabbit R1 offers would work as an Android or even iOS app. The only functions that wouldn't work are unrelated to the product's core functionality and are things your phone can already do, such as powering off or rebooting the device, toggling Bluetooth, connecting to a cellular or Wi-Fi network, or setting a screen lock. During our research, Android Authority was also able to obtain a copy of the Rabbit R1's firmware. Our analysis reveals that Rabbit did not make significant modifications to the BSP (Board Support Package) provided by MediaTek. The R1, in fact, still ships with all the standard apps included in AOSP, as well as the many apps provided by MediaTek. This is despite the fact that none of these apps are needed nor ever shown to the user, obviously. Rabbit only made a few changes to the AOSP build that MediaTek provided them, such as adding the aforementioned R1 launcher app, adding a fork of the open-source "AnySoftKeyboard" app with a custom theme, adding an OTA updater app, and adding a custom boot animation. [...] Yes, it's true that all the R1 launcher does is act as a local client to the cloud services offered by Rabbit, which is what truly handles the core functionality. It's also true that there's nothing wrong or unusual with companies using AOSP for their own hardware. But the fact of the matter is that Rabbit does little to justify its use of custom hardware except by making the R1 have an eye-catching design.

Alternative Clouds Are Booming As Companies Seek Cheaper Access To GPUs

✇Slashdot
Par : BeauHD
6 mai 2024 à 22:02
An anonymous reader quotes a report from TechCrunch: CoreWeave, the GPU infrastructure provider that began life as a cryptocurrency mining operation, this week raised $1.1 billion in new funding from investors, including Coatue, Fidelity and Altimeter Capital. The round brings its valuation to $19 billion post-money and its total raised to $5 billion in debt and equity -- a remarkable figure for a company that's less than 10 years old. It's not just CoreWeave. Lambda Labs, which also offers an array of cloud-hosted GPU instances, in early April secured a "special purpose financing vehicle" of up to $500 million, months after closing a $320 million Series C round. The nonprofit Voltage Park, backed by crypto billionaire Jed McCaleb, last October announced that it's investing $500 million in GPU-backed data centers. And Together AI, a cloud GPU host that also conducts generative AI research, in March landed $106 million in a Salesforce-led round. So why all the enthusiasm for -- and cash pouring into -- the alternative cloud space? The answer, as you might expect, is generative AI. As the generative AI boom times continue, so does the demand for the hardware to run and train generative AI models at scale. GPUs, architecturally, are the logical choice for training, fine-tuning and running models because they contain thousands of cores that can work in parallel to perform the linear algebra equations that make up generative models. But installing GPUs is expensive. So most devs and organizations turn to the cloud instead. Incumbents in the cloud computing space -- Amazon Web Services (AWS), Google Cloud and Microsoft Azure -- offer no shortage of GPU and specialty hardware instances optimized for generative AI workloads. But for at least some models and projects, alternative clouds can end up being cheaper -- and delivering better availability. On CoreWeave, renting an Nvidia A100 40GB -- one popular choice for model training and inferencing -- costs $2.39 per hour, which works out to $1,200 per month. On Azure, the same GPU costs $3.40 per hour, or $2,482 per month; on Google Cloud, it's $3.67 per hour, or $2,682 per month. Given generative AI workloads are usually performed on clusters of GPUs, the cost deltas quickly grow. "Companies like CoreWeave participate in a market we call specialty 'GPU as a service' cloud providers," Sid Nag, VP of cloud services and technologies at Gartner, told TechCrunch. "Given the high demand for GPUs, they offers an alternate to the hyperscalers, where they've taken Nvidia GPUs and provided another route to market and access to those GPUs." Nag points out that even some Big Tech firms have begun to lean on alternative cloud providers as they run up against compute capacity challenges. Microsoft signed a multi-billion-dollar deal with CoreWeave last June to help provide enough power to train OpenAI's generative AI models. "Nvidia, the furnisher of the bulk of CoreWeave's chips, sees this as a desirable trend, perhaps for leverage reasons; it's said to have given some alternative cloud providers preferential access to its GPUs," reports TechCrunch.

'The Good Enough Trap'

An anonymous reader shares an essay: Software designers refer to "the good enough principle." It means, simply put, that sometimes you should prioritise functionality over perfection. As a relentless imperfectionist, I'm inclined to embrace this idea. I gave this newsletter its name to encourage myself to post rough versions of my pieces rather than not to write them at all. When it comes to parenting, I'm a Winnicottian: I believe you shouldn't try to be the perfect mum or dad because there's no such thing. At work and in life, it's often true that the optimal strategy is not to strive for the optimal result, but to aim for what works and hope for the best. The good enough can be a staging post to the perfect. The iPhone's camera was a "good enough" substitute for a compact camera. It did the job, but it wasn't as good as a Kodak or a Fuji. Until it was. Technological innovation often works like this, but the improvement curve isn't always as steep as with the smartphone camera.
