  • GPUs that are banned from export to China can be easily acquired in low numbers in the country due to individuals bringing in banned GPUs which get sold just like unbanned GPUs after passing through several people. Also possible that some banned cards are repaired QC failures from the Chinese factories that produce these cards (the cards are produced in China, but are supposed to be exported and banned from export back into China). The export restrictions present more of a barrier for building out large AI clusters with many, many GPUs.
    Nvidia almost certainly knows about this but turns a blind eye because they want to sell more cards and China is a large market.
    There are some repair shops in China that can not only repair the GPUs, but can also transfer the GPU die onto an aftermarket PCB and give it double the amount of VRAM to create a card that Nvidia doesn’t even sell.
    Individual banned GPUs are easier to get than the full systems that Nvidia also sells. AMD GPUs are much less popular, Intel GPUs are basically non-existent. The overall most popular card for smuggling into China seems to be the RTX 4090.



    • For Steam apps, the previous method doesn’t work (for some reason - maybe it uses a custom launch process?), but after trying many different ways, I was able to get most Steam apps to use the correct GPU (GPU 0) by adding the custom launch option PROTON_USE_WINED3D=0 %command%

    Steam runs the commands to launch the games directly, so editing .desktop files won’t affect anything launched through steam directly.
    PROTON_USE_WINED3D=0 is related to the graphics back ends, so I wouldn’t use it for selecting the GPU, as, while it might work for making a game use the dedicated GPU, it probably won’t work reliably as you’ve discovered. For setting a game to run on the NVIDIA GPU I think PRIME and NVIDIA Optimus are the solution, but I can’t help you much since all my systems have only a single GPU enabled. One of the following 3 launch options in steam should work:
    __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia __VK_LAYER_NV_optimus=NVIDIA_only %command%

    DRI_PRIME=1 %command%

    prime-run %command%



  • 111 isn’t an urgent line (if it’s genuinely an emergency go to A&E or call 999) and from personal experience it takes hours for them to get back to you, at which point you’ve either already told them your symptoms have got worse, still had no call back and gone to A&E or they get back to you eventually and tell you that you might be fine, but should go to the hospital anyway and sit in a queue for 6 hours so they can make sure it’s not actually something serious. NHS 111 is just as useless as the NHS Direct it replaced

    For GP appointments that are released on the day, in the morning, you can avoid waiting in a long call queue to the GP by booking the appointment through the NHS app if your GP supports it.








  • For security disable password authentication - use public key instead, disable root login via ssh - use sudo or su from another user.

    To reduce the number of attempts of others trying to get in change the ssh port and/or set-up fail2ban.

    You could also set a firewall rule to only allow ssh from your IP address, if you have a static address at home and only need access from there, or have a way to VPN into your home network. Make sure you have a static address if you do this though, you don’t want your IP to change and be left locked out of your server.
