  • 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.


  • Yeah, I search the AUR not to discover packages, but to see if something I want to install is in there, if it is I check the PKGBUILD and make sure none of the sources/commands/patches are suspicious.
    People need to remember it’s not some carefully vetted app store and that they need to be the ones vetting any packages they install and any changes when updating.







  • 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.






  • Runways can be used from either direction, usually they try to land with a headwind if there is significant wind I think. I think the localizer antenna can be at both ends of the runway if both directions have ILS approaches, but I’m not an expert. The concrete mound for the antenna is getting a lot of focus because it made a runway excursion so much worse.

    It seems to me like they may have decided to make the landing then due to losing altitude and thinking they wouldn’t be able to climb again, but hopefully the investigation can figure out what probably happened.
