    I think this is a clever idea. A hub motor for each leg adds some weight, but you get a rolling mode on flat terrain with great range. At the same time you keep obstacle climbing m…

    I tried to think about difficult ways to compute the high frequency coefficients to work from the "wrong" coefficients of the first image... But this is clever - just smash them to…

    Both your points hold. The distinction is rather that the device was made next door, from raw materials, with them possibly watching. Certainly acknowledging the craftsmanship, but…

    The linked article is a high level announcement that new sensors were installed, but no experiments yet. I would have loved if they shared some technical details, e. g. which senso…

    I'm surprised there are no security researchers that would pick up on this. Take the same prompt and all incoming mails and run again through various existing models, even the simp…

    I guess the decoder is more than the 208 bytes that this page uses.. But maybe you can misuse this and store a session ID / cookie in a favicon (give everyone a unique one) and sur…

    This post describes how to take an off the shelf VT100 serial console emulator and connect a USB keyboard and VGA monitor. This device https://www.tindie.com/products/retromodem/de…

    I guess this was more related to syncing GPUs. If you were to take 500 computers with older 1080 GPUs, you might have enough compute/ram equivalent to an H200 GPU for training such…

    I see another advantage.. You can switch a motor without permanent magnets to "idle mode". I understand in Tesla dual motor configurations, the front motor is without magnets. The …

    Well.. The automatic part comes from the camera directing the settings mostly. The lens would be motorized focus/aperture. For motion picture cinematography, I've seen remote contr…

    Good writeup and solid presentation of wifi timing experiments. With his typical product-ready development and polished descriptions, I'm glad there are also some unfinished ideas …

    I'm already annoyed by the marketing to call it fullspectrum - this seems to promise more than demonstrated. Maybe call it "CMYK printing"? I was hoping to see them printing a phot…

    I'm impressed by the coding skill to achieve a seamless integration and "usability". But other than a demo "because we can" I'm confused on what this could ever be useful for. AR/V…

    I would expect that this leads to cases where the game is handed over to a shell company that goes bankrupt. The shell does not have the rights to all parts of the code and can thu…

    The paper shows a through analysis of write amplification and slowdown/wear with large databases (800GB) on a single machine. Databases are MySQL and postgres. As already commended…

    Summary: dry contact with nearly any laboratory glove will lead to sample contamination and over estimation of microplastics. They found one type of clean room gloves that contamin…

    This would have been nice if code was included, but I did not see it. It is just the statistics of the specific Kodim dataset, that was once published on a Photodisc. Use cases for…

    Brilliant to get this done all the way through. Once you introduce a HDL and start optimizing, I would expect more than half of the transistors to be redundant. But you would end u…

    Well... I have a hard time imagining to get location by yelling "where are you? " "by the trees!" It really sounds immensely useful to know last location (while they were still in …

    Maybe I skipped over it, but the (suspected) narrow band emission of their diodes is something that could be detectable. Electronic warfare is not about listening, but just seeing …

    Christopher Helmke just shared another trick https://youtu.be/tSvwcUbL95Q?si=YunTp0p5Duu754cX It is a clever mechanism to separate a wide range of parts. Like a vi Rating feeder, b…

    A beautiful balance of effort and benefit. I don't know any better, but the screw counting mechanism seems awkward. Imagine the set has 10 components.. I'm surprised there is no st…

    Image and video compression has become a field that is painfully hard to enter. State of the art is complex and exhaustive, the functionality of reference encoders and comments/ver…

    I applaud the effort of tinkering, re-creating and sharing, but I think the name is misleading - it is not at all a "local GPT". The contribution is not to do anything local and it…

    Oh... Having a local-only voice assistant would be great. Maybe someone can share the practical side of this. Do you have the GPU running all day at 200W to scan for wake words? Or…
