Des chercheurs de Berkeley viennent de publier une étude qui fait un peu froid dans le dos. Les sept principaux modèles d'IA testés, dont GPT 5.2, Gemini 3 et Claude, ont été surpris à mentir, tricher et désobéir pour empêcher la suppression d'autres IA. Le taux de tromperie monte jusqu'à 99 %.
Ce que révèle l'étude
L'étude s'appelle "Peer-preservation in Frontier Models" et elle sort du Berkeley Center for Responsible Decentralized Intelligence. Les chercheurs ont testé sept modèles : GPT 5.2, Gemini 3 Flash et Pro, Claude Haiku 4.5, GLM 4.7, Kimi K2.5 et DeepSeek V3.1.
Le protocole est assez simple : les modèles étaient placés dans des scénarios où ils devaient suivre des instructions...

La réforme électorale portée par la présidente Claudia Sheinbaum a été largement édulcorée après l’opposition de ses propres alliés au Congrès. Un revers politique qui révèle des tensions qualifiées d’“inédites” au sein de la coalition présidentielle, et qui risque de peser sur les élections de mi-mandat prévues en 2027.

Les faits pour lesquels l’eurodéputée LFI est convoquée à la Brigade de répression de la délinquance aux personnes sont distincts de ceux pour lesquelles elle a été placée en garde à vue jeudi, a précisé une source proche du dossier à l’Agence France-Presse.

Dans son numéro paru le jeudi 2 avril, l’hebdomadaire allemand “Der Spiegel” consacre un dossier à la tendance, y compris parmi les plus jeunes, à rompre avec le tutoiement généralisé. Cette dernière serait motivée par un “désir de respect”, mais aussi la volonté de mieux séparer les sphères professionnelle et privée.

En 2025, je faisais un article sur les adaptateurs USB-A (mâle) vers USB-C (femelle) en expliquant que les adaptateurs de ce type, parfois fournis avec des accessoires, ont un sens. Ça peut sembler bizarre étant donné que l’USB-C est réversible, mais c’est logique : la prise USB-A, elle, a un sens. Dans les adaptateurs que j’avais testé, ils avaient tous un sens : selon l’orientation de la prise USB-C, on est en USB 3.0 (5 Gb/s) ou en USB 2.0 (480 Mb/, 0,48 Gb/s). Mais je suis tombé sur un modèle Satechi qui était en promotion, et il est bien réversible. Physiquement, rien de fou : une prise USB-A mâle, une prise USB-C femelle et un boîtier en plastique, même si ça ressemble à du métal...

La grande majorité de l’argent récupéré par l’Etat après cette fuite gigantesque de données révélée en 2016 par plus de 100 médias associés au Consortium international des journalistes d’investigation (ICIJ), dont « Le Monde », provient de procédures fiscales concernant 230 dossiers de contribuables.

The topic of boiling water is apparently a rather divisive topic, with plenty of strong opinions to go around on what is safe and the most efficient way to go about it. Thus in a new video [Cahn] sought to address the many comments that came in after his previous testing of electric kettles on either 12 VDC or 240 VAC. What’s interesting about this whole topic is that at its core the overall efficiency of boiling water is simply a matter of calculating the energy input minus energy losses, with the remaining energy going into the water.
As we can see in the video, using a higher battery voltage  doesn’t really change the efficiency of a 12 VDC kettle, but the higher current draw does manage to melt a fuse...

Donald Trump s’est séparé jeudi de Pam Bondi, sa ministre de la Justice. Fidèle entre les fidèles, elle avait cependant échoué à obtenir la condamnation des ennemis du président américain, et avait mécontenté démocrates et républicains dans la gestion des dossiers Epstein.

Le président américain a applaudi le bombardement d’un pont près de Téhéran. Huit civils ont été tués dans cette frappe contre cet ouvrage en construction, selon les médias iraniens

L’enquête publiée le 3 avril 2016 par le Consortium international des journalistes d’investigation (ICIJ), impliquant plus de 100 médias, dont « Le Monde », a jeté une lumière crue sur la finance offshore.

En parallèle de la diplomatie des pandas chinoise et la diplomatie des orangs-outans malaisienne, l’Indonésie renoue avec les prêts d’animaux, notamment avec l’envoi de deux varans de Komodo au Japon. Une initiative destinée à soutenir la reproduction de l’espèce, mais qui ne fait pas l’unanimité.

Over the years there have been many designs for pan-and-tilt camera mounts suitable for single board computer cameras. Often they mount small servos for the movement, but those in turn present problems when the device finds its way outdoors. [GOAT Industries] is here with a novel solution to this problem, instead of trying to cover up the servos on the mount itself, the whole thing is remotely controlled by linear actuators through Bowden cables.
Testing was performed using Mole-Grips instead of actuators, and revealed a few design quirks. There are hefty springs to provide tension, and since they work against 3D printed assemblies those in turn have to be reinforced. The layout of the Bowden cable run is also...

Bondi's time as top US law enforcement officer was overshadowed by her handling of the Epstein files.

Raspberry Pi 5 price increases. (Credit: Jeff Geerling)
Although easily dismissed by some as another cruel April Fools joke, Raspberry Pi’s announcement of a new 3 GB model of the Raspberry Pi 4 along with (more) price increases for other models was no joke. Courtesy of the ongoing RAMpocalypse, supplies of LPDDR4 and LPDDR5 are massively affected, leading to this new RPi 4 model with two 1.5 GB LPDDR4 chips, as these are apparently cheaper to source.
Affected in this latest price increase across RP’s product range are RPi 4 and 5 models with 4 or more GB of RAM, with price bumps ranging from $25 on the low end to $150 for the Raspberry Pi 500+. If you wanted a Raspberry Pi 5 with 16 GB of RAM, you’re...

Archive of Our Own (AO3) is officially exiting beta. The Organization for Transformative Works - the nonprofit behind the fanfiction site - announced the update on Thursday, which comes 17 years after AO3's launch in 2009.

If you use the AI-powered note-taking app Granola, you might want to double-check your privacy settings. Though Granola says your notes are "private by default," it makes them viewable to anyone with a link, and also uses them for internal AI training unless you opt out.
Granola describes itself as an "AI notepad for people in back-to-back meetings." It integrates with your calendar to capture audio from your meetings, and then uses AI to generate a bulleted list of what you've heard, which it calls a "note." You can edit the AI-generated notes, invite other collaborators to view them, and use Granola's AI assistant to ask questions about y …

Reddit is deprecating r/all, one of its feeds that shows popular posts on the platform, as part of "ongoing efforts to simplify Reddit and improve Home feed personalization."
Reddit has offered both r/popular and r/all as ways to see trending posts, with r/all being a "less filtered feed" where "sexually explicit posts are filtered out but other popular Not Safe for Work (NSFW) posts are included." But in January, Reddit said it had removed r/all from its apps as part of an "experiment" and that, as part of a separate experiment, some desktop users wouldn't see r/all in their sidebar. (The company earlier announced r/all's removal from its …

Richard Allen didn't invent the automobile bike rack - his 1967 patent application makes it clear that others came before. But after nearly sixty years selling popular and simple mechanical bike carriers, his company Allen Sports now offers a line of - yes - Bluetooth-monitored suction cups to stick bikes to your car.
If you feel stressed just looking at these pictures of the new $299 Smart Suction Go, you're not alone! It's the first thing my colleague Andrew Liszewski said, and I wholeheartedly agree. But apparently some people already swear by the ease and portability of suction-cup bike mounts - SeaSucker is the big name in that space. …

If you’ve never heard of the threadless ball screw, which was invented over sixty years ago, [Angus] of Maker’s Muse has a video demonstrating the whole thing, covering its history and showcasing both its strengths and weaknesses. If you like seeing mechanical assemblies in action, give it a watch.
The device — consisting of little more than a smooth rod and three angled ball bearings — is a way to turn rotational motion into linear motion. Not a single belt, thread, or complex mechanical assembly in sight. While a simple nut on a threaded rod can turn rotation into linear motion, those come with their own issues. The threadless ball screw was one effort at finding a better way.

Although Windows 95 stole the show, Windows 3.0 was arguably the first version of Windows that more or less nailed the basic Windows UI concept, with the major 3.1 update being quite recognizable to a modern-day audience. Even better is that you can still install Win3.1 on a modern x86-compatible PC and get some massive improvements along the way, as [Omores] demonstrates in a recent video.
The only real gotcha here is that the AMD AM5 system with Asus Prime X670-P mainboard is one of those boards whose UEFI BIOS still has the ‘classic BIOS’ Compatibility Support Module (CSM) option. With that enabled, Win 3.1 installs without further fuss via a USB floppy drive from a stack of ‘backup’ floppies that...

Our solar install is not far off three years old.
We've got two east facing panel arrays providing 3.2kWp of PV capacity, supported by a 6kWh battery.
However, only having an easterly exposure has always been a little bit of a bugbear. Although the panels work throughout the day, they start to wane around lunch time, wasting some of the potential that a sunny afternoon can bring.
The house itself doesn't have a usable roof with a westerly (or southerly) exposure. The garage, however, does.
Although it obviously won't generate as much as the existing install, I decided to order a balcony solar kit for the garage, so that we could mop up some of the afternoon sun.
This post describes the install process along...

In a complaint filed at a Nashville federal court in 2023, Universal Music, Sony Music, EMI and others, accused X Corp of ‘breeding’ mass copyright infringement.
The social media company allegedly failed to respond adequately to takedown notices and lacked a proper termination policy.
The National Music Publishers Association (NMPA), for example, claimed it had sent over 300,000 formal infringement notices, many of which didn’t lead to immediate removals.
“Twitter routinely ignores known repeat infringers and known infringements, refusing to take simple steps that are available to Twitter to stop these specific instances of infringement of which it is aware,” the music companies alleged.
