Optical connectivity – and especially silicon photonics – is expected to become a crucial technology to enable connectivity for next-generation datacenters, particularly those designed HPC applications. With ever-increasing bandwidth requirements needed to keep up with (and keep scaling out) system performance, copper signaling alone won't be enough to keep up. To that end, several companies are developing silicon photonics solutions, including fab providers like TSMC, who this week outlined its 3D Optical Engine roadmap as part of its 2024 North American Technology Symposium, laying out its plan to bring up to 12.8 Tbps optical connectivity to TSMC-fabbed processors.
TSMC's Compact Universal Photonic Engine (COUPE) stacks an electronics integrated circuit on photonic integrated circuit (EIC-on-PIC) using the company's SoIC-X packaging technology. The foundry says that usage of its SoIC-X enables the lowest impedance at the die-to-die interface and therefore the highest energy efficiency. The EIC itself is produced at a 65nm-class process technology.
TSMC's 1st Generation 3D Optical Engine (or COUPE) will be integrated into an OSFP pluggable device running at 1.6 Tbps. That's a transfer rate well ahead of current copper Ethernet standards – which top out at 800 Gbps – underscoring the immediate bandwidth advantage of optical interconnects for heavily-networked compute clusters, never mind the expected power savings.
Looking further ahead, the 2nd Generation of COUPE is designed to integrate into CoWoS packaging as co-packaged optics with a switch, allowing optical interconnections to be brought to the motherboard level. This version COUPE will support data transfer rates of up to 6.40 Tbps with reduced latency compared to the first version.
TSMC's third iteration of COUPE – COUPE running on a CoWoS interposer – is projected to improve on things one step further, increasing transfer rates to 12.8 Tbps while bringing optical connectivity even closer to the processor itself. At present, COUPE-on-CoWoS is in the pathfinding stage of development and TSMC does not have a target date set.
Ultimately, unlike many of its industry peers, TSMC has not participated in the silicon photonics market up until now, leaving this to players like GlobalFoundries. But with its 3D Optical Engine Strategy, the company will enter this important market as it looks to make up for lost time.

Google says it has patched a nasty loophole in the Android TV account security system, which would grant attackers with physical access to your device access to your entire Google account just by sideloading some apps. As 404 Media reports, the issue was originally brought to Google's attention by US Sen. Ron Wyden (D-Ore.) as part of a "review of the privacy practices of streaming TV technology providers." Google originally told the senator that the issue was expected behavior but, after media coverage, decided to change its stance and issue some kind of patch.
"My office is mid-way through a review of the privacy practices of streaming TV technology providers," Wyden told 404 Media. "As part of that inquiry, my staff discovered an alarming video in which a YouTuber demonstrated how with 15 minutes of unsupervised access to an Android TV set-top box, a criminal could get access to private emails of the Gmail user who set up the TV."
The video in question was a PSA from YouTuber Cameron Gray, and it shows that grabbing any Android TV device and sideloading a few apps will grant access to the current Google account. This is obvious if you know how Android works, but it's not obvious to most users looking at a limited TV interface.

Hackers are assailing websites using a prominent WordPress plugin with millions of attempts to exploit a high-severity vulnerability that allows complete takeover, researchers said.
The vulnerability resides in WordPress Automatic, a plugin with more than 38,000 paying customers. Websites running the WordPress content management system use it to incorporate content from other sites. Researchers from security firm Patchstack disclosed last month that WP Automatic versions 3.92.0 and below had a vulnerability with a severity rating of 9.9 out of a possible 10. The plugin developer, ValvePress, silently published a patch, which is available in versions 3.92.1 and beyond.
Researchers have classified the flaw, tracked as CVE-2024-27956, as a SQL injection, a class of vulnerability that stems from a failure by a web application to query backend databases properly. SQL syntax uses apostrophes to indicate the beginning and end of a data string. By entering strings with specially positioned apostrophes into vulnerable website fields, attackers can execute code that performs various sensitive actions, including returning confidential data, giving administrative system privileges, or subverting how the web app works.
On Thursday, the US Department of Energy released its preliminary estimate for the nation's carbon emissions in the previous year. Any drop in emissions puts us on a path that would avoid some of the catastrophic warming scenarios that were still on the table at the turn of the century. But if we're to have a chance of meeting the Paris Agreement goal of keeping the planet from warming beyond 2° C, we'll need to see emissions drop dramatically in the near future.
So, how is the US doing? Emissions continue to trend downward, but there's no sign the drop has accelerated. And most of the drop has come from a single sector: changes in the power grid.
US carbon emissions have been trending downward since roughly 2007, when they peaked at about six gigatonnes. In recent years, the pandemic produced a dramatic drop in emissions in 2020, lowering them to under five gigatonnes for the first time since before 1990, when the EIA's data started. Carbon dioxide release went up a bit afterward, with 2023 marking the first post-pandemic decline, with emissions again clearly below five gigatonnes.

Spy Pet, a service that sold access to a rich database of allegedly more than 3 billion Discord messages and details on more than 600 million users, has seemingly been shut down.
404 Media, which broke the story of Spy Pet's offerings, reports that Spy Pet seems mostly shut down. Spy Pet's website was unavailable as of this writing. A Discord spokesperson told Ars that the company's safety team had been "diligently investigating" Spy Pet and that it had banned accounts affiliated with it.
"Scraping our services and self-botting are violations of our Terms of Service and Community Guidelines," the spokesperson wrote. "In addition to banning the affiliated accounts, we are considering appropriate legal action." The spokesperson noted that Discord server administrators can adjust server permissions to prevent future such monitoring on otherwise public servers.

DaVinci Resolve 19 est un logiciel de montage vidéo performant, complet, efficace et qui a le bon goût d’être absolument gratuit. Il existe deux versions de ce logiciel. La première est la version Studio, qui est payante et qui ajoute des tonnes de fonctionnalités très avancées. La seconde est la même, sans ces fonctions avancées mais qui est absolument gratuite.
Et DaVinci Resolve 19 a beau être gratuit, ce n’est pas un logiciel qui fait dans la demie mesure. On peut tout faire avec. Du montage de vidéo multipistes sur des projets très lourds, de la correction et de l’étalonnage de couleurs, des effets spéciaux, de la correction et modification de son, du rendu de qualité et tout ce que l’on demande à un logiciel professionnel de montage vidéo. En fait DaVinci Resolve est un logiciel professionnel de montage vidéo, tout simplement.
Une des nuance qui existe entre la version Studio et la version gratuite depuis toujours est la prise en charge des circuits graphiques pour effectuer des calculs de décodage des fichiers que vous employez. Sur la version Studio, les cartes graphiques sont gérées pour exploiter leurs capacités de calcul massives afin d’accélérer les temps de traitement. C’est un argument fort pour pousser les gens a passer à la version payante du logiciel. Quand vous avez des rushes enregistrés dans des formats exigeants, il faut beaucoup trop de ressources pour que des processeurs seuls s’en sortent confortablement. Un film UltraHD en H.265 par exemple, si vous mélangez plusieurs de ces flux et demandez au logiciel de faire de la correction de couleur ou autre en prime, votre processeur sera à genoux pendant votre montage. Mettant parfois plusieurs secondes a afficher le rendu de votre image à l’écran. Et cela même si vous avez une carte graphique surpuissante dans votre PC puisqu’elle ne sera pas prise en compte par le logiciel.
La détection des dialogues automatisée de Studio permet de générer des sous titres automatiquement
Cette version 19, encore en Beta pour le moment, permet donc de profiter de ce décodage matériel assuré par les circuits graphiques et cela change considérablement la donne. La version Studio existe toujours et elle est encore vendue à un tarif très raisonnable de 330€ TTC en une licence unique.
Pourquoi Blackmagic a t-il décidé d’abandonner cet avantage aux utilisateurs qui ne payent pas de licence ? Probablement parce que ces derniers temps la marque a rajouté des tonnes de nouvelles fonctions liées à l’IA pour la version Studio. Et que ces nouveaux éléments font désormais suffisamment la différence. La version Studio propose des effets d’image comme la réduction de bruit et la correction automatique de couleurs suivant des scénarios. Elle propose également des fonctions de reconnaissance de la voix et de sous-titrage ainsi que des éléments de tracking d’objets, de floutage d’arrière plan, des fonctions de travail collaboratif et autres. Autant de fonctionnalités qui ont pris clairement le relais comme des avantages suffisants pour leur offre payante. Cet usage intelligent et impressionnant de l’IA est peut être le meilleur argument pour le nom choisi par la marque, c’est vraiment de la « magie noire » quand on le découvre.
Caméra et panneau de contrôle signés BlackMagic Design
Il y a également le fait que Blackmagic se sert de son lofgiciel pour vendre du materiel : consoles de montage, d’étalonnage mais aussi ensemble de materiel de studio et de caméras. Des éléments qui montent régulièrement en gamme et qui filment à des définitions de plus en plus élevées dans des formats de plus en plus exigeants. Pour que sa version gratuite de Resolve ait du sens, il est nécessaire qu’elle puisse gérer ces outils de manière efficace. Et cela passe par la prise en charge des circuits graphiques.
Pour télécharger Davinci Resolve 19, cela se passe par ici.

TikTok owner ByteDance is preparing to sue the US government now that President Biden has signed into law a bill that will ban TikTok in the US if its Chinese owner doesn't sell the company within 270 days. While it's impossible to predict the outcome with certainty, law professors speaking to Ars believe that ByteDance will have a strong First Amendment case in its lawsuit against the US.
One reason for this belief is that just a few months ago, a US District Court judge blocked a Montana state law that attempted to ban TikTok. In October 2020, another federal judge in Pennsylvania blocked a Trump administration order that would have banned TikTok from operating inside the US. TikTok also won a preliminary injunction against Trump in US District Court for the District of Columbia in September 2020.
"Courts have said that a TikTok ban is a First Amendment problem," Santa Clara University law professor Eric Goldman, who writes frequent analysis of legal cases involving technology, told Ars this week. "And Congress didn't really try to navigate away from that. They just went ahead and disregarded the court rulings to date."

Microsoft has open-sourced another bit of computing history this week: The company teamed up with IBM to release the source code of 1988's MS-DOS 4.00, a version better known for its unpopularity, bugginess, and convoluted development history than its utility as a computer operating system.
The MS-DOS 4.00 code is available on Microsoft's MS-DOS GitHub page along with versions 1.25 and 2.0, which Microsoft open-sourced in cooperation with the Computer History Museum back in 2014. All open-source versions of DOS have been released under the MIT License.
Initially, MS-DOS 4.00 was slated to include new multitasking features that allow software to run in the background. This release of DOS, also sometimes called "MT-DOS" or "Mutitasking MS-DOS" to distinguish it from other releases, was only released through a few European PC OEMs and never as a standalone retail product.
Bonjour,
Je souhaite proposer aux utilisateurs de DeltaCMS une méthode permettant d’intégrer sur leur site un Framagenda. Le CMS possède déjà un module agenda mais je trouve Framagenda facile à utiliser et puis j’ai vu sur un des sites deltacms un très vilain google agenda !
J’ai suivi la méthode pour récupérer le code d’intégration, le résultat est très satisfaisant en grand écran ( largeur >1000 px ) mais en petit écran la partie menu (supérieure) n’est pas du tout responsive. Et comme 90% des consultations de pages web se font à partir d’un smartphone j’hésite à poursuivre
C’est dommage que pour la version embed de l’agenda les concepteurs n’aient pas utilisé le même css que pour une vue directe de l’agenda qui elle est parfaitement responsive avec un menu disposé à gauche et qui devient burger en petit écran.
Une modification du CSS de la version embed est-elle envisageable ?
Cordialement
Sylvain Lelièvre

Tesla's lousy week continues. On Tuesday, the electric car maker posted its quarterly results showing precipitous falls in sales and profitability. Today, we've learned that the National Highway Traffic Safety Administration is concerned that Tesla's massive recall to fix its Autopilot driver assist—which was pushed out to more than 2 million cars last December—has not actually made the system that much safer.
NHTSA's Office of Defects Investigation has been scrutinizing Tesla Autopilot since August 2021, when it opened a preliminary investigation in response to a spate of Teslas crashing into parked emergency responder vehicles while operating under Autopilot.
In June 2022, the ODI upgraded that investigation into an engineering analysis, and in December 2023, Tesla was forced to recall more than 2 million cars after the analysis found that the car company had inadequate driver-monitoring systems and had designed a system with the potential for "foreseeable misuse."

Le Geekom A8 est annoncé ! En décembre 2023 le fabricant indiquait l’arrivée des Geekom A8 Max et A8Pro. Le A8 Max devait embarquer des puces Ryzen 7 8840HS et Ryzen 9 8940HS. Le Geekom A8 « tout court » proposera des solutions Hawk Point Ryzen 7 8845HS et Ryzen 9 8945HS.
On retrouve le même format de machine avec un MiniPC très traditionnel de 11.7 cm de large pour 11.2 cm de profondeur et 3.42 cm d’épaisseur. Une taille qui ne lui permet pas de fantaisies au niveau stockage., On retrouvera donc à son bord un unique port M.2 2280 aux format NVMe PCIe Gen4 x4 et SATA3. Pas de second port de stockage ni de baie 2.5″ mais un double slot SODIMM DDR5-5600. Ces éléments seront donc en compagnie de deux processeurs AMD.
| Cores / Threads | Boost/Base Frequency | Cache | TDP | cTDP | NPU | |
| AMD Ryzen 9 8945HS | 8C/16T | 5.2 GHz / 4.0 GHz | 24MB | 45W | 35 – 54W | Oui |
| AMD Ryzen 7 8845HS | 8C/16T | 5.1 GHz / 3.8 GHz | 24MB | 45W | 35 – 54W | Oui |
Des puces Zen 4 au TDP assez élevé dans cette gamme de minimachines avec 45 watts annoncés et un cTDP programmable de 35 watts. On ne sait pas pour le moment quel sera la consommation retenue par le constructeur. Dans tous les cas ces processeurs proposeront un excellent circuit graphique Radeon 780M en RDNA 3 ainsi qu’un NPU maison.
La connectique embarquée sera très complète avec en tout trois ports USB 3.2 Gen 2 Type-A plus un au format Type-C avec Power Delivery, un USB4, un USB 2.0, un jack audio combo 3.5 mm, un Ethernet 2.5 Gigabit, deux HDMI 2.0 et un lecteur de cartes SDXC. Une distribution réalisée dans un châssis en aluminium monobloc ventilé de manière classique avec des micro perforations sur le côté et une évacuation de l’air chaud vers l’arrière. Deux caloducs transporteront la chaleur vers des ailettes placées devant l’extraction d’un ventilateur de type portable pour la repousser vers l’extérieur.
Un module Wi-Fi7 et Bluetooth 5.4 trouvera sa voie au travers d’antennes probablement placées sur la partie arrière de l’engin, seul élément plastique capable de laisser passer le signal sans fil de la machine. Enfin, une licence de Windows 11 Pro sera préinstallée sur les modèles équipés de mémoire et de stockage. Pas d’idée précise sur le prix ni sur la date de disponibilité de ces deux machines mais j’ai cru comprendre qu’elles seront mise en vente dans les prochains mois.

Enlarge / The slide-on Joy-Con connection point shown in the center of the image may be a thing of the past on the Switch 2
The iconic slide-in "click" of the Switch Joy-Cons may be replaced with a magnetic attachment mechanism in the Switch 2, according to a report from Spanish-language gaming news site Vandal.
The site notes that this new design could make direct Switch 2 backward compatibility with existing Switch Joy-Cons "difficult." Even so, we can envision some sort of optional magnetic shim that could make older Joy-Cons attachable with the new system's magnetic connection points. Current Switch Pro Controllers, which do not physically attach to the Switch, should be fully compatible with the Switch 2, according to the report.
Vandal cites several unnamed accessory and peripheral makers who reportedly got to touch the new console inside of an opaque box, which was used to balance design secrecy with the need to provide general knowledge of the unit's dimensions. According to those sources, the Switch 2 will be "larger than the Switch, although without reaching the size of the Steam Deck."
