    Yesterday, Microsoft announced that it made 31 percent less off Xbox hardware in the first quarter of 2024 (ending in March) than it had the year before, a decrease it says was "driven by lower volume of consoles sold." And that's not because the console sold particularly well a year ago, either; Xbox hardware revenue for the first calendar quarter of 2023 was already down 30 percent from the previous year.

    Those two data points speak to a console that is struggling to substantially increase its player base during a period that should, historically, be its strongest sales period. But getting wider context on those numbers is a bit difficult because of how Microsoft reports its Xbox sales numbers (i.e., only in terms of quarterly changes in total console hardware revenue). Comparing those annual shifts to the unit sales numbers that Nintendo and Sony report every quarter is not exactly simple.

    Context clues

    To attempt some direct contextual comparison, we took unit sales numbers for some recent successful Sony and Nintendo consoles and converted them to Microsoft-style year-over-year percentage changes (aligned with the launch date for each console). For this analysis, we skipped over each console's launch quarter, which contains less than three months of total sales (and often includes a lot of pent-up early adopter demand). We also skipped the first four quarters of a console's life cycle, which don't have a year-over-year comparison point from 12 months prior.

      Google parent Alphabet hits $2tn valuation as it announces first dividend

      news.movim.eu / TheGuardian · Yesterday - 15:27

    Tech company’s shares rise as it plans to reward investors after strong quarterly results

    Google’s parent company has hit a stock market value of $2tn (£1.6tn) as investors reacted to a declaration of its first ever dividend alongside strong results on Thursday.

    Shares in Alphabet rose 10% in early Wall Street trading on Friday to give the tech group a stock market capitalisation – a measure of a corporation’s value – of more than $2tn. Alphabet last hit that level in intraday trading in 2021, but has yet to close above that benchmark after a day’s trading.

      Multitasking MS-DOS 4 – L’OS oublié de Microsoft

      news.movim.eu / Korben · Yesterday - 06:00 · 3 minutes

    Multitasking MS-DOS 4 . Rien que le nom ça fait rêver. Un nom qui respire le futur, qui transpire l’innovation. Mais c’est quoi en fait ?

    Et bien au début des années 80, alors qu’on se battait encore en duel avec des disquettes 5″1/4, Microsoft avait dans ses cartons un projet d’OS révolutionnaire baptisé Multitasking MS-DOS 4. Bon, ce n’est pas le nom le plus sexy de l’histoire de l’informatique mais derrière cette appellation austère se cachait un système d’exploitation qui promettait déjà le multitâche et tout un tas de fonctionnalités incroyables pour l’époque !

    L’histoire commence en 1983 lorsque Microsoft rassemble une équipe de développeurs talentueux pour plancher sur la nouvelle version de MS-DOS, qui doit apporter un max de nouveautés pour l’époque : multitâche, multi-threading, pipes, sémaphores… Tout ça sur les modestes processeurs 8086/8088 qui avaient une mémoire limitée.

    Le projet s’appelle d’abord MS-DOS 3.0 avant d’être renommé MS-DOS 4.0 en avril 1984. En parallèle, Microsoft travaille sur le « vrai » DOS 3.0 qui sortira en août 1984. Vous suivez ? C’est un peu le bazar mais c’est ça qui est bon !

    Puis en juin 1984, une première beta de Multitasking DOS 4 est envoyée à quelques privilégiés. Et autant vous dire que ça décoiffe ! Le multitâche fonctionne déjà, géré par un composant baptisé « Session Manager ». On peut lancer jusqu’à 6 applications en même temps en leur attribuant des raccourcis clavier. Le Session Manager gère aussi les fameuses « erreurs fatales » qui pouvaient faire planter tout le système. Avec lui, si un programme plante, il n’embarque pas tout le système avec lui. C’est un concept révolutionnaire pour l’époque !

    MS-DOS 4.0 apportait également son lot d’améliorations comme une meilleure gestion de la mémoire, le support des disques durs de plus de 10 Mo (si si, à l’époque c’était énorme !), une API étendue, et même un système de fichiers réseau (Microsoft Networks).

    Le développement de ce MS-DOS 4.0 s’est fait en étroite collaboration avec IBM car le géant informatique planchait à l’époque sur son propre OS avec une architecture similaire à MS-DOS 4.0. Mais plutôt que de se faire concurrence, Microsoft et IBM ont décidé de joindre leurs forces. MS-DOS 4.0 a ainsi servi de base au développement d’IBM PC-DOS 4.0. Les deux OS partageaient une grande partie de leur code source et étaient compatibles entre eux. Une belle démonstration du partenariat entre Microsoft et IBM !

    Malheureusement, malgré toutes ses qualités, MS-DOS 4.0 n’a jamais été commercialisé. Son développement a été stoppé au profit d’OS/2, le nouveau projet de Microsoft et IBM et la plupart de ses fonctionnalités ont été recyclées dans ce nouvel OS.

    Multitasking MS-DOS 4 est ainsi resté à l’état de projet, même si certaines de ses innovations ont survécu dans d’autres OS. Son code source est longtemps resté dans les cartons de Microsoft, jusqu’à ce que l a société décide de le libérer en open source, sous licence MIT . Un joli cadeau pour les passionnés d’histoire de l’informatique !

    Alors si vous êtes curieux d’essayer MS-DOS 4.0 par vous-même, sachez que c’est possible ! Grâce à la libération du code source, des passionnés ont pu recompiler l’OS et le faire tourner sur des machines modernes via des émulateurs comme DOSBox.

    Voici les étapes pour lancer MS-DOS 4.0 sur votre PC :

    1. Téléchargez l’émulateur DOSBox sur le site officiel
    2. Installez DOSBox sur votre machine
    3. Récupérez une image disque de MS-DOS 4.0. Vous pouvez en trouver sur des sites d’archives comme WinWorldPC
    4. Ouvrez DOSBox et montez l’image disque de MS-DOS 4.0 avec la commande :
      mount c /chemin/vers/image_dos4.img -t iso
    5. Démarrez MS-DOS 4.0 en tapant : c:

    Sinon, vous pouvez le tester directement en ligne ici .

    Et voilà, vous pouvez maintenant explorer ce morceau d’histoire de l’informatique et découvrir par vous-même les prémices du multitâche sous DOS !

    Amusez-vous bien !

    Microsoft releases one of the most popular versions of MS-DOS as open source today. stikves shares a post:Ten years ago, Microsoft released the source for MS-DOS 1.25 and 2.0 to the Computer History Museum, and then later republished them for reference purposes. This code holds an important place in history and is a fascinating read of an operating system that was written entirely in 8086 assembly code nearly 45 years ago. Today, in partnership with IBM and in the spirit of open innovation, we're releasing the source code to MS-DOS 4.00 under the MIT license. There's a somewhat complex and fascinating history behind the 4.0 versions of DOS, as Microsoft partnered with IBM for portions of the code but also created a branch of DOS called Multitasking DOS that did not see a wide release.

    Logitech announced a new mouse last week. A company rep reached out to inform Ars of Logitech’s “newest wireless mouse.” The gadget’s product page reads the same as of this writing.

    I’ve had good experience with Logitech mice, especially wireless ones, one of which I'm using now . So I was keen to learn what Logitech might have done to improve on its previous wireless mouse designs. A quieter click ? A new shape to better accommodate my overworked right hand? Multiple onboard profiles in a business-ready design?

    I was disappointed to learn that the most distinct feature of the Logitech Signature AI Edition M750 is a button located south of the scroll wheel. This button is preprogrammed to launch the ChatGPT prompt builder, which Logitech recently added to its peripherals configuration app Options+.

    In the world of AI, what might be called "small language models" have been growing in popularity recently because they can be run on a local device instead of requiring data center-grade computers in the cloud. On Wednesday, Apple introduced a set of tiny source-available AI language models called OpenELM that are small enough to run directly on a smartphone. They're mostly proof-of-concept research models for now, but they could form the basis of future on-device AI offerings from Apple.

    Apple's new AI models, collectively named OpenELM for "Open-source Efficient Language Models," are currently available on the Hugging Face under an Apple Sample Code License . Since there are some restrictions in the license, it may not fit the commonly accepted definition of "open source," but the source code for OpenELM is available.

    On Tuesday, we covered Microsoft's Phi-3 models , which aim to achieve something similar: a useful level of language understanding and processing performance in small AI models that can run locally. Phi-3-mini features 3.8 billion parameters, but some of Apple's OpenELM models are much smaller, ranging from 270 million to 3 billion parameters in eight distinct models.

    Qualcomm says lower-end Snapdragon X Plus chips can still outrun Apple’s M3

    Qualcomm’s Snapdragon X series of chips promises to be the company’s first that can go toe-to-toe with Apple Silicon, and the PC ecosystem is reacting accordingly . Microsoft reportedly plans for the Arm version of its next Surface tablet to be the flagship, and major apps like Chrome and Dropbox have recently released Arm-native Windows versions for the first time.

    Ahead of the chips' launch late this year, Qualcomm announced a new lower-end model destined for cheaper devices. Dubbed the Snapdragon X Plus, it shares a lot in common with the flagship Snapdragon X Elite .

    The Snapdragon X Plus includes 10 CPU cores instead of the Elite’s 12, though the more noticeable change is its lack of support for clock-speed boosting; the chip’s 3.4 GHz base frequency is as fast as it goes, where the Elite chips can boost two cores to 4.2 GHz and one core up to 4.3 GHz, depending on the specific model. Qualcomm also rates the X Plus’ integrated GPU at 3.8 TFLOPs, down from the X Elite’s maximum of 4.6 TFLOPs. Aside from those high-level FLOP numbers, we still know very little about how the GPU will be configured; we also don’t know the ratio of “big” and “little” CPU cores.

      Microsoft’s Phi-3 shows the surprising power of small, locally run AI language models

    On Tuesday, Microsoft announced a new, freely available lightweight AI language model named Phi-3-mini, which is simpler and less expensive to operate than traditional large language models (LLMs) like OpenAI's GPT-4 Turbo . Its small size is ideal for running locally, which could bring an AI model of similar capability to the free version of ChatGPT to a smartphone without needing an Internet connection to run it.

    The AI field typically measures AI language model size by parameter count. Parameters are numerical values in a neural network that determine how the language model processes and generates text. They are learned during training on large datasets and essentially encode the model's knowledge into quantified form. More parameters generally allow the model to capture more nuanced and complex language-generation capabilities but also require more computational resources to train and run.

    Some of the largest language models today, like Google's PaLM 2 , have hundreds of billions of parameters. OpenAI's GPT-4 is rumored to have over a trillion parameters but spread over eight 220-billion parameter models in a mixture-of-experts configuration. Both models require heavy-duty data center GPUs (and supporting systems) to run properly.
