  • Why are you being so condescending about this?

    FPGAs are a great tool, but they’re not magic.

    They are a great way to prototype ASICs or for performing relatively simple low latency/high-throughput tasks below the economies of scale where actually taping out an ASIC would make sense but there is pretty much no case where an FPGA with a bunch of the same logic path is going to outperform a dedicated ASIC of the same logic.

    NPUs are already the defacto ASIC accelerator for ML. Trying to replicate that functionality on an FPGA fabric of an older process node with longer path lengths constraining timing is going to be worse than a physically smaller dedicated ASIC.

    It was the same deal with crypto-mining, the path for optimizing parallel compute is often doing it badly on a GPU first, moving to FPGA if memory isn’t a major constraint, then tape out ASICs once the bugs in the gateware are ironed out (and economies of scale allow)

    And that doesn’t even begin to cover the pain of FPGA tooling in general and particularly vendor HLS stacks.














  • Used Ubuntu for ~15 years, switched to NixOS a couple months ago and haven’t looked back.

    I’ve made a habit of clean installing all of the desktops/laptops/servers in my life on the first point release of each LTS (i.e. 22.04.1). That would mean there was time for the dust to settle and for me to tweak my install/customization scripts from the previous LTS.

    So since I knew I was gonna have to modify my Ubuntu install scripts to work with 24.04 anyways, I fiigured it was a decent time to try and see if I could get the install scripts converted to a nix config instead, and it ended up working a treat.



  • The Walmart app provides historical receipt data if you have an associated card. A few months ago I spot-checked a ‘standard basket of goods’ (food and household items often repurchased) for myself between then and the end of 2019 (right before covid), and the average increase in price of those goods over that period of time was just about 50% overall for my personal basket of goods.
