  • I really have a hard time deciding if that is the scandal the article makes it out to be (although there is some backpedaling going on). The crucial point is: 8% of the decisions turn out to be wrong or misjudged. The article seems to want us to think that the use of the algorithm is to blame. Yet, is it? Is there evidence that a human would have judged those cases differently? Is there evidence that the algorithm does a worse job than humans? If not, then the article devolves onto blatant fear mongering and the message turns from “algorithm is to blame for deaths” into “algorithm unable to predict the future in 100% of cases”, which of course it can’t…


  • That’s what happens when a) the CPU manufacturer drives the chips to the absolute limit in order to “win the benchmarks” b) then the mainboard manufacturer drives the chips even further in order to “win the benchmarks” and then c) the user goes over even that because the CPU is “overclockable” (which is sold as a feature) and one wants to “win the benchmarks”

    And all of that, while the added performance of high-tier CPUs and/or overclocking, is often minimal in the grand scheme of things at best. CPUs get marketed and hyped by the media with percentages, not with absolute numbers. Want to know why that is? Because a “10% performance increase” sounds substantial, right? Well, humans are rubbish when it comes to intuition and numbers. A 10% performance plus is an increase from 100FPS to 110FPS. Depending on how sensitive you are to FPS, that might be visible, for many others it’s just not. Yet, those increases come at hefty costs regarding power consumption and heat generated, usually. The lesson is: Going for the fastest, beefiest CPU is a bad idea in about 90% of use cases, I’d say.









  • Why can’t you? I don’t see where the issue is. During password creation, you choose your organization and it’s done. If the entry already exists, edit the entry and choose the organization under “owner”. It’s four clicks max. Do you use this so differently than I do?




  • BEFORE you mess with your VNC, it is extremely important to have a backup connection. So either you have the ability to connect your pi to a monitor and a keyboard locally, or you really, really should setup SSH before you mess with your VNC server.

    Use SSH with a Certificate, described here: https://raspberrypi-guide.github.io/networking/connecting-via-ssh (“passwordless”) This guide doesn’t show how to set up SSH, but how to install a key in a more detailed way: https://pimylifeup.com/raspberry-pi-ssh-keys/

    The good thing: Once you got this working, you’re basically done. Just ditch VNC and go straight to SSH from now on. It’s more secure and has better performance usually.

    Yet, if you like your VNC and want to continue using it, you first connect via SSH do not do this while using a VNC connection! Now, first, you do all this: https://www.tomshardware.com/how-to/install-vnc-raspberry-pi-os then you do a

    sudo update-alternatives --list vncserver
    sudo update-alternatives --list vncserver-x11
    

    you should see tightvnc listed there. Don’t freak out if one of the two returns an error that the application was not found. That’s okay. Not all versions of Raspbian used the same application name in the past, so I listed them both. As long as one of them works, you’re fine.

    Then, you do a

    sudo update-alternatives --config vncserver
    sudo update-alternatives --config vncserver-x11
    

    and change it to tightvnc. now you can stop your running VNC:

    sudo vncserver-x11 -service -stop && sudo vncserver -service -stop
    sudo vncserver-x11 -service -start && sudo vncserver -service -start
    

    Once you did that, connect to tightvnc as described in the article. If this works, do sudo apt uninstall realvnc

    You should now be able to connect via VNC without weird account bullshit.
