    We shouldn't forget that the movements in memory manufacturers are because datacenter demands pays more compared with consumers demands.

    It's kinda "race". If consumers pay more, datacenters would pay even more.
    This means "cost pressures" on datacenters become higher and it should cause the fee for datacenters to be more expensive.

    So I think keeping data "in premise" being still competitive.

  • Hardware Store Marauder’s Map is Clarkian Magic

    The “Marauder’s Map” is a magical artifact from the Harry Potter franchise. That sort of magic isn’t real, but as Arthur C. Clarke famously pointed out, it doesn’t need to be — we have technology, and we can make our own magic now. Or, rather, [Dave] on the YouTube Channel Dave’s Armoury can make it.

    [Dave]’s hardware store might be in a rough neighborhood, since it has 50 cameras’ worth of CCTV coverage. In this case, the stockman’s loss is the hacker’s gain, as [Dave] has talked his way into accessing all of those various camera feeds and is using machine vision to track every single human in the store.

    Of course, locating individuals in a video feed is easy — to locate them in space from that feed, one first needs an accurate map. To do that, [Dave] first 3D scans the entire store with a rover. The scan is in full 3D, and it’s no small amount of data. On the rover, a Jetson AGX is required to handle it; on the bench, a beefy HP Z8 Fury workstation crunches the point cloud into a map. Luckily it came with 500 GB of RAM, since just opening the mesh file generated from that point cloud needs 126 GB. That is processed into a simple 2D floor plan. While the workflow is impressive, we can’t help but wonder if there was an easier way. (Maybe a tape measure?)

    Once an accurate map has been generated, it turns out NVIDIA already has a turnkey solution for mapping video feeds to a 2D spatial map. When processing so much data — remember, there are 50 camera feeds in the store — it’s not ideal to be passing the image data from RAM to GPU and back again, but luckily NVIDIA’s “Deep Stream” pipeline will do object detection and tracking (including between different video streams) all on the GPU. There’s also pose estimation right in there for more accurate tracking of where a person is standing than just “inside this red box”. With 50 cameras, it’s all a bit much for one card, but luckily [Dave]’s workstation has two GPUs.

    Once the coordinates are spat out of the neural networks, it’s relatively simple to put footprints on the map in true Harry Potter fashion. It really is magic, in the Clarkian sense, what you can do if you throw enough computing power at it.

    Unfortunately for show-accuracy (or fortunately, if you prefer to avoid gross privacy violations), it doesn’t track every individual by name, but it does demonstrate the possibility with [Dave] and his robot. If you want a map of something… else… maybe check out this backyard project.

    @bianot Che io sappia esistono diversi studi sul sonno che avrebbero dimostrato che stare davanti a uno schermo quando è sera riduce la produzione di melatonina e quindi ti fa dormire di meno con tutto quello che ne segue. Questo perché il cervello "crede" (a causa della luce dello schermo) che sia ancora giorno e ti incasina i ritmi circadiani secondo i quali quando fa buio si deve andare a nanna. Poi sicuramente affaticare gli occhi leggendo molto non fa bene e questo a qualsiasi ora...

    Salve a tutte e tutti. Dovrei contattare per lavoro (non per offrire un lavoro!) persone che hanno scritto o sono "nel giro" della saggistica sul videogioco in italiano, ma che abbiano un buon livello di inglese parlato. Ossia che hanno studiato dinamiche, realtà, possibilità del mondo dei videogiochi, meglio se italiani, e poi fatto pubblicazioni.Scrivetemi anche in privato, se preferite, se volete altre info o non sono stato chiaro. Grazie.#mastoaiuto #videogames #saggistica

    Ma veramete il link ufficiale della Italian Tech Resistance è uno spazio social di Meta?Io cerco e cerco ma finisco sempre su instamerd/italian_tech_resistance/#mastoaiutoEDIT 1 link infoautohttps://infoaut.org/confluenza/la-tecnologia-non-salvera-il-mondo-intelligenza-artificiale-e-data-center-tra-false-promesse-e-sfruttamento-dei-territoriEdit 2 ho trovato questo gancio di 7 ore fa: https://gancio.cisti.org/event/italian-tech-resistance

    @talksina Errore mio, non è org ma com.Ad ogni modo ci sono riuscito, bastava scaricare l'app per il cellulare e da lì c'è un'opzione specifica per collegarlo al proprio account mastodon.Semplice e intuitivo direi (sono ironico).Grazie mille!@blog
