    Those are symptoms of sitting at that operation point permanently, and they are a of course a concern. What I’m after is that people think that energy gets put in to the battery, i.e. it gets charged, as long as a “charger” is connected to the device (hence terms like “overcharged”). But that is not true, because what is commonly referred to as “charger” is no charger. It is just a power supply and has literally zero say in if, how and when the battery gets charged. It only gets charged if the charge controller in the device decides to do that now, and if the protection circuit allows it. And that is designed to only happen if the battery is not full. When it is full, nothing more happens, no currents flow in+out of the battery anymore. There’s no damage due to being charged all the time, because no device keeps on pumping energy into the cell if it is full.

    There is however damage from sitting (!) at 100% charge with medium to high heat. That happens indipendently from a power supply being connected to the device or not. You can just as well damage your cells by charging them to 100% and storing them in a warm place while topping them of once in a while. This is why you want to have them at lower room temperature and at ~60%, no matter if a device/“charger” is connected or not.

    (Of course keeping a battery at 60% all the time defeats the purpose of the battery. So just try to keep it cool, charged to >20% and <80% most of the time, and you’re fine)


  • “overcharging” doesn’t exist. There are two circuits preventing the battery from being charged beyond 100%: the usual battery controller, and normally another protection circuit in the battery cell. Sitting at 100% and being warm all the time is enough for a significant hit on the cell’s longetivity though. An easy measure that is possible on many laptops (like thinkpads) is to set a threshold where to stop charging at. Ideal for longetivity is around 60%. Also ensure good cooling.

    Sorry for being pedantic, but as an electricial engineer it annoys me that there’s more wrong information about li-po/-ion batteries, chargers and even usb wall warts and usb power delivery than there’s correct information.


  • It is not that easy to understand what you want, to me it reads like you want something like Nextcloud - i.e. your own little cloud, where you can put all your stuff, and view it through the webbrowser or the nextcloud apps, and also keep selected parts of your stuff in sync with your devices (or automatically upload photos take with your smartphone for example).

    Backup of Nextcloud (or whatever you want to use) is a seperate topic. Any incremental backup tool would apply though, so there’s much to choose from. I personally use btrbk which uses Btrfs Send+Receive to push incremental snapshots to an offsite server.




  • We recently moved away from Trello and settled on GitLab. Might sound a weird decision at first glance, but you can just create an empty repo, create issues instead of cards and visualize them in den “Boards” view.

    Key drivers for doing so were that we rely heavily on GitLab already, and that we wanted a trustworthy solution in terms of data privacy. But I guess you’d have a bit of a hard time selling this to an audience that has no experience with GitLab, so decide for yourself if its viable in your case


  • The bitwarden clients also work when there’s no connection to the server, since they sync the vault. You just can’t add any new entries. That means spotty internet is not that much of an issue in terms of using it. It also means, that every device that has a client installed and gets used regularly (to give the client a chance of syncing) is automatically a backup device.


  • To give you an idea of what you’ll experience in your self-hosting journey: adding services is the easy part, maintaining a system in production over many years is the hard part. And the self hosting solutions you mean are quite bad at that. Eventually I ditched even Proxmox because its updates are cumbersome and you never know wheter you’ll end up with a working system after the upgrade.

    Ultimately, you want to avoid any complex transitions in your system altogether. Decouple everything, make everything disposable, especially your OS. The ootb-selfhosting-solutions are the antithesis of that: lots of hidden magic behind colorful buttons, which makes it immensely hard to get a working setup the second something goes wrong. And that will inevitably happen with time passing.

    What happens in the Windows world: Microsoft is not capable of creating and distributing a patch timely. Or they wait for “patch day”, the made up nonsense reason to delay patches for nothing. Also since Windows has no sensible means of keeping software up to date, the user itself has to constantly update every single thing, with varying diligence. Hence Antivirus: there is so much time between a virus becoming known and actual patches landing on windows, that antivirus vendors can easily implement and distribute code that recognizes that virus in the meantime.

    What happens in the linux world: a patch is delivered often in a matter of hours, usually even before news outlets get to report about the vulnerability.






  • Do you do some sort of versioning/snapshotting of your services? I’m on the compose route as well, and have one btrfs subvolume per service that holds the compose.yml and all bind-mounted folders for perstistent data. That again gets regularly snapshotted by snapper.

    What leaves me a bit astounded is, that nobody seems to version the containers they are running. But without that, rolling back if something breaks might become a game of guessing the correct container version. I started building a tool that snapshots a service, then rewrites the image: in compose.yml to reflect what ever the current :latest tag resolves to. Surprisingly, there doesn’t seem to be an off-the-shelf solution for that…
