    A couple things to check using a quick bash script:

    #!/usr/bin/env bash
    
    cd /sys/class/power_supply/BAT*/
    echo "Charge cycles: $(cat cycle_count)"
    printf '%s\0' 'Health: ' &
    bc <<< "scale=3; ($(cat charge_full) / $(cat charge_full_design)) * 100"
    

    That should print out the wear cycles the battery has endured and its reported capacity over design capacity. If your battery has less than 1000 cycles and the health reported from the battery is less than 80%, it might be best to contact Framework for warranty replacement as the battery is likely defective.


  • Just note that with Bambu printers about past data collection practices and their in general mid to atrocious after-sales support. If this doesn’t deter you, then go ahead and get one.

    I do a lot of my functional parts in ABS, ASA though printing such material may be difficult on an open-air machine. The two obvious choices will generally be PLA or PETG. PLA is one of the most common printed materials, and is fairly balanced in material strength. PETG parts are more likely to permanently deform heavily before fully snapping, as well as they have a but more temperature resistance than PLA. Additionally most PETG plastics hold up decently well to UV, often making them more suitable for parts that need to be outdoors.

    PLA takes not much consideration on surface to print, as most printers come with a smooth PEI build sheet by default. It will however need more cooling than printing with PETG at equivalent speeds. If you use a PEI sheet for PETG, make sure it is textured. You will destroy a smooth sheet if it doesn’t have some kind of release coating to lower its adhesive properties to PETG.

    There is no guarantee for spools of filament to actually arrive dry, so a filament dryer isn’t a bad idea. I don’t have any particular recommendations for a good filament dryer. I have a Filadryer S2 from Sunlu, but am not impressed by it.














  • The flatpak documentation has a semi-relevant page on setting up a flatpak repo utilizing gitlab pages and gitlab’s CI runners on a pipeline. Obviously, you’d need to substitute Gitlab Pages for a webserver of your choice and to port the CI logic over to Gitea Actions (ensuring your Gitea instance is setup for it).

    A flatpak repo itself is little more than a web server with a related GPG key for checking the signatures of assembled packages. The docs recommend setting up the CI pipeline to run less on-commit to the package repos and more on the lines of checking for available updates on interval, though I imagine other scenarios in a fully-controlled environment such as a selfhosted one might offer some flexibility.


  • As I am teaching myself right now maintainable selfhost setups using popular apps (admittedly with Kubernetes vs something minimal in functionality like Docker Desktop), there is a lot of complexity involved in getting these services both functional and maintainable while also having to consider the security implications of various setups.

    While I agree the concept of self-host is a good thing to advocate, I think the complexity and difficulty involved not just to do it, but to do it right is going to be a straight cliff of a learning curve for those not already technically inclined in databases, networking, and filesystems/block storage.

    Honestly, taking the burden of being IT for a reasonable subscription cost for your efforts is a better way to go, especially if the setup allows for expanding your offerings to other members in a localized community.



  • The headphones you have don’t have any actual surround sound capabilities. The only thing they do is have a software driver that maps a set of channels from 7.1 surround sound to the binaural sound mapping of the headphones.

    The pipewire sound server can do the same thing as iCue with filter chains and specific plugins. See this post for some pointers and guidance if you wish to set it up for yourself.

    Do note that unless you have content built with actual 5.1 or 7.1 surround sound, there won’t be much actual benefit to using virtual surround sound on headphones in the first place.

    As I found out recently myself, you should almost always set the minimum amount of reserved memory for the iGPU on modern hardware. The reserved memory is just that— reserved. The kernel still dynamically allocates memory for GPU usage as needed on iGPUs.

    Alongside many others, I agree that using QEMU through GUI frontends like virt-manager or GNOME Boxes, or even server-focused solutions like Cockpit+VM plugin or Proxmox layered on top of your installation.

    I just want to note a decent point against other solutions like VirtualBox or the VMWare products that work on Linux: these solutions that don’t rely on QEMU almost certainly need the user to install out-of-tree kernel modules (that in some cases may also be proprietary). QEMU and its frontends don’t need out-of-tree modules in a majority of distros and can work out of the box with all features (given BIOS configuration of the host and hardware supports them).


  • I started dual booting Linux after an upgrade to an insider preview of Windows 10 soft-bricked my Windows 7 install. I later stopped booting into Windows and eventually reclaimed the partitions to extend whatever distro was installed at that point when the actual release of Windows 10 decided to attempt automatically upgrading my Windows 7 system, soft-bricking it a second time. 2016 onwards, I haven’t used Windows on my systems outside of occasionally booting LTSC in a VM.
