  • At least the ones on the north east coast are close to the wind farms.

    The ones around London are in the worst place imaginable. We all know the state of Thames water, and it’s got the least excess power. Scottish wind farms keep on getting curtailed at great expense. We literally have power to spare up there, but I expect it’s the financial services firms saying they need low latency links to the financial markets.

    We’re a country with a gambling addiction.











  • Risc-V has a base specification and then a bunch of extensions. RV64G is almost as basic as you can get. It has 64-bit registers as opposed to RV32s 32-bit ones and it has floating point instructions. C adds compressed instructions which are good for keeping more code in cache.

    RVA23 is a “profile” which includes a lot more extensions. 56-bit virtual memory, vector processing, and hypervisor mode being the big ones. I don’t think anybody has come out with a RVA23 compliant piece of silicon yet.

    So Debian is supporting existing hardware and Ubuntu has ditched support for the existing processors and is supporting what is currently yet to appear.
