  • The worst gotchas and limitations I have seen building my own self-host stack with ipv6 in mind has been individual support by bespoke projects more so system infrastructure. As soon as you get into containerized environments, things can get difficult. Podman has been a pain point with networking and ipv6, though newer versions have become more manageable. The most problems I have seen is dealing with various OCI containers and their subpar implementations of ipv6 support.

    You’d think with how long ipv6 has been around, we’d see better adoption from container maintainers, but I suppose the existence of ipv6 in a world originally built on ipv4 is a similar issue of adoption likewise to Linux and Windows as a workstation. Ultimately, if self-rolling everything in your network stack down to the servers, ipv6 is easy to integrate. The more one offloads in the setup to preconfigured and/or specialized tools, the more I have seen ipv6 support fall to the wayside, at least in terms of software.

    Not to mention hardware support and networking capabilities provided by an ISP. My current residential ISP only provides ipv4 behind cgnat to the consumer. To even test my services on ipv6, I need to run a VPN connection tunneling ipv6 traffic to an endpoint beyond my ISP.

    Beyond the article being ancient at this point (in terms of AOSP and Android development lifetime), Stallman’s argument boils down to the same talking points of Free Software purism.

    To the first real point being transformed here: Android is not GNU/Linux because it does not contain much of the GNU Project’s software. While it’s correct to claim it’s not GNU/Linux, how does it not make it Linux still? Is Alpine Linux not considered “Linux” because it doesn’t contain GNU? Please elaborate on this point of Linux being Linux because it has GNU.

    To the second point of including proprietary drivers, firmware, and appplications: we once again meet the questionable argument of transforming an OS to something else. Points are made that Android doesn’t fit the GNU ideals due to its usage and inclusion of proprietary kernel modules, firmware, and userland applications. These are valid points to be made in that these additions muddy the aspect of Android (as packaged by Google and major smartphone manufacturers) being truly free software. However the same can be said about traditional “GNU/Linux distributions”. Any device running on x86 (Intel, AMD) will be subject to needing proprietary firmware in order to function with that firmware having a higher control level than the kernel itself, just as Android would. There is also the note that while it is less necessary now to have a functioning desktop, a good portion of hardware (NVidia, Broadcom, Intel, etc.) require proprietary kernel modules and/or userland drivers in order to have full functionality that the average user may want. Finally, there is proprietary applications as well. Some Linux desktops include proprietary applications like Spotify, Steam, Google Chrome by default. Are we really to also exclude an overwhelming majority of the biggest Linux distros as Linux as well being that they include proprietary software or rely on proprietary code in some fashion? GNU itself lists very few distros as GNU-approved.

    To note, AOSP does have a different userland environment than your standard Linux distro running X11 or Wayland. That is by far the best reason I could think of to classify Android as a different category of ‘Linux’ from say Debian, Fedora, OpenSUSE, Arch, Gentoo, Slackware, and others. However, AOSP is still capable of running with no proprietary userland software and can even be made to still run cli applications as well as run an X11 server that is capable of launching familiar desktop Linux applications. I really think that the arbitrary exclusion of Android from being Linux by virtue that RMS doesn’t think it fits with GNU ideals is silly. If there are better arguments to be said for why Android (especially AOSP) shouldn’t be seen as Linux with a different userland ecosystem rather than not Linux entirely, I’d love to see them. However, I remain unconvinced so far.


  • I have been utilizing BunkerWeb for some of my selfhost sites since it was bunkerized-nginx. It is indeed powerful and flexible, allowing multi-site proxying, hosting while allowing semi-flexible per-site security tweaks (some security options are forcibly global still, a limitation).

    I use it on podman myself, and while it is generally great for having OWasp CRS, general traffic filtering targets and more built on top of nginx in a Docker container, the way Bunkerweb needs to be run hasn’t really remained stable between versions. Throughout several version upgrades, there have been be severe breaking changes that will require reading the setup documentation again to get the new version functional.


  • Before going any further to adjust your Z offset and other factors to tune for better bed adhesion, you should probably adjust your bed to actually be level as well as ensure (seeing that you only have one z lead screw?) that the X axis frame isn’t sagging on the side not containing your Z lead screw. Once you’ve got those factors sorted out, you should check your probe repeatability and then set your Z offset accordingly.

    Bed adhesion even with proper, clean first layers can be a pain depending on the bed surface, material being printed, how clean the bed is of oils and other contaminants, how hot the material is being extruded, and how hot the bed is among other factors. While using a bed mesh will greatly help to account for off-zero unevenness in your bed surface, you really shouldn’t use it to compensate for uneven bed leveling (especially when it looks like you are nearing more than 0.5 mm in unevenness).

    To diagnose other print issues, it will be helpful to see a picture showcasing the problems described in a failed print.


    As a side note, it is somewhat difficult to read your Klipper config file without using view source as it is being markdown formatted. You can negate it by using three graves on the lines above and below it so that it is wrapped in a ‘code block’ and isn’t formatted.
