  • My summary of that whole 12VHPWR situation:

    • Still no hard data on failure rates. We simply don’t know if the 12VHPWR is more error-prone. There is however less wiggle room for imperfections because 600W is a lot of power.

    • Igor writes like NVIDIA is some kind of bad villain that infiltrated the PCI SIG. I have no idea how the PCI SIG works, I simply find it laughable to think that NVIDIA can dictate stuff to the PCI SIG. It is a consortium with experts from AMD, NVIDIA, Intel, and many, many more people and companies. To suggest otherwise is dishonest.

    • There were badly produced ASTRON adapters

    • CableMod adapters are a stupid idea to begin with. Unlike a cable, a hard PCB has no wiggle room and thus can not compensate for a non-perfect production.

    • Flipped ASUS design is a bad idea

    • Igor again argues that NVIDIA tried to blame users for user errors. I agree that there could have been a better design that allows for more wiggle room and user error. But then again, without any numbers on how many cards actually failed it is hard to tell. What if this is not really an issue in real life? What if besides ASTRON, ASUS, and CableMod adapters, millions of cards work flawlessly and only a handful of users are affected? Even to Igor’s own numbers (which he got from CableMod), if we leave out the twisted ASUS design, it is an extremely small issue.

    • Igor again argues that NVIDIA blames users because it would have affected Q3 results negatively. Assuming this is true, why did it not affect later quarterly results? Also, why should any at NVIDIA care? Because otherwise, they would have to do insider trading and sell their stocks before the bad news. That is not how it works.

    • PCI acknowledged design flows and came up with 12V-2×6. You could now scream “See?! The old 12VHPWR was bad! That is why they changed it!” but that does not have to be true. If a Boeing crashed, because there was ice on the ground speed sensor, it is easy to say “Well, there needs to be redundancy and some kind of heating, this is a stupid design to begin with, how did the FAA approve that? Boeing probably pressured the FAA! And they hide the truth because quarterly earnings are up.” If Boeing then does implement these changes, it is still not a gotcha moment.

    I like the work Igor has done here. These old-school electrical engineers who later switched or grew into IT are very much needed. They offer excellent knowledge. And I think if we look at Igor’s reporting, we can feel that he had a lot of fun and put his heart into it. But it also affected his objectivity. He himself acknowledges that! That is not easy, hats off!




  • It is not green to repair a phone, it is green to get a case for your phone so you don’t destroy it in the first place.

    Also I saw way more phones and laptops go into the trash because I could not buy a replacement part (2,5y old Acer Laptop, according to Acer end of life, could not find a new battery) or because software support ended (Windows 10 support will end 2025, lots of laptops don’t meet the hardware requirement for Win11, or smartphones like Galaxy S20 only getting 3y of security updates) is a WAY bigger factor than „easy repairability“.

    I also don’t agree that something is difficult to repair, just because you need some tools or have to peel of some glue that prevented water damage of thousands of smartphones. I also don’t agree with the iFixit conclusion that it is anti consumer that the iOS tells the customer if the screen, battery or something else was replaced, which could potentially be of worse quality. As long as the device does not block these parts (which it does not to my knowledge) I think it is pro consumer because it prevents second hand ripoff’s.




  • We also simply apply the batch AI to stuff we already did years ago but did not call it AI back then. Like, Airbus using machine learning to find better and lighter shapes for airplane parts.

    And for stuff like writing code, it turns out to be not as helpful as expected. It is impressive for coding noobs like me. According to people I know that code for a living, it is not that big of a deal. A nice addition that helps a little bit on some tasks.

    AI really shines in tasks where accuracy is not important. Like making up stories, drawing pictures, creating designs and logos, and writing buzzword PR. And of course rule 34!



  • Remember 4y ago, when 5G was the next big thing?

    Self-driving cars thanks to 5G?

    Every industry will be transformed and every single production line will have a 5G campus network.

    We will only stream games over 5G!

    5G was so frigging important, we needed to ban Huawei from building cell towers because otherwise, they could shut down our whole economy because our whole economy depends on 5G?

    Well, that turned out to be a hype. Of course, it did not go away, just like AI will not go away. But it will have a completely different focus, than what most think now. I see a bigger future for AI in girlfriend simulators or user preference adult movies than in replacing STEM jobs.



  • PermitRootLogin I would set to yes.

    sudo systemctl restart ssh will only restart your ssh client and not the ssh server you try to restart. Use sshd insted.

    I personally find it easier to use no root during setup and import my ssh keys from github using ssh-import-id.

    UFW doesn’t harm, but if the host is on your Proxmox Hypervisor, it is probably behind a deny all incoming firewall anyway. That is also why I would leave IPv6 on.

    Like other have noted, Crowdsec is a little bit more complex to setup but also offers more features. As a side note, Fail2ban is unfortunatly not IPv6 ready.
