  • @evan @mayintoronto wow. You made me realise I have not used a word processor for the past month! Woohoo! That was fun!

    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.

    @SteveClough @cstross I write nothing more creative than documentation for the software I produce, but people misunderstand that, too.The experience of people misunderstanding my docs, or simply failing to read them, was one of the things that turned me away from evangelicalism. (I bet you didn't see that coming.) I wasn't using parables to hint at ineffable spiritual truths in the face of religious persecution: I was just explaining how software worked, how to see its current state, and how to configure and maintain systems. People who were paid to read and understand this material would not or could not do so: their repeated questions made it obvious. Within a very few years, instead of reading TFM, people developed folk stories of commands they could type that usually did something that could be mistaken for success. They veered constantly off-course, and I kept having to drag them back. They consulted each other, rather than the docs, and developed their own mythology about how the software worked. They intuitively felt they knew the software better than I did, because my approach to problem-solving was careful and methodical but they knew a golden shortcut.If concrete, human-level explanations, written out literally, landed so badly, there's no chance that people will have remembered the figurative and unfathomable teachings of Jesus seventy years after his death, written them down accurately and fully, and built from them a useful picture of worlds seen and unseen and the will of God. I'm sorry; it just doesn't ring true.

    #writersCoffeeClub 4 Nov 'What's the funniest thing you've ever written?'The dinner party in "The Nightmare Stacks". Alex, a CS nerd (turned vampire) is visiting his very conventional middle-class parents: he takes his new girlfriend Cassie (an elven spy who is helping to pave the way for an invasion) on the back of his borrowed ... conveyance. Then they discover his sister has brought her girlfriend too, and the misconceptions start to spiral ...

    Ooh I thought of another aspect of letters within fiction. A letter or any other text message is unlike dialog in that it persists to be re-read later, maybe not by the intended recipient, and can be loaded with hidden meanings that you wouldn't expect someone to pick up on or remember accurately if they heard the same words spoken.I used this twice in The Silk Mind, in a letter to the Badger Survey from Doctor Grey, and rather pointed diplomatic letters between him and Celandine.
