Is #Thunderbird really the only standalone #Linux desktop calendar app that can just subscribe to #CalDAV calendars? 🤨
#GnomeCalendar needs a ton of dependencies and #GNOME stuff running.
#KOrganizer the same for #KDE.
#Evolution apparently just hooks into GNOME online accounts.
There are some terminal calendar apps, but yeah... If one has #vim keybindings and is configurable via config files, I am open to suggestions.

2025-10-22 10:34:45 GMT

Oh. my. god. is :thunderbird: #Thunderbird's calendar broken. It keeps asking for passwords. And of course doesn't tell for which calendar 🤪. Apparently the only thing it can do is associate a base (!) url (not the full calendar url, no no no) to ONE user/password combination. You have a server with multiple accounts of which you want to access the calendars? No. You put the user@... into the url? Same shit. Something must have changed recently. It was always sketchy, but this is unworkable.

I see two solutions:
1. Add a separate input with your desired nixpkgs, and pin it either manually with the commit in the url, or only nix flake update it individually
2. Put your derivation into a separate flake with its own pinning.

Well yeah, your nixpkgs commit c7ab75210cb8 indeed uses a now deprecated Signal desktop version, so you would need to update your nixpkgs channel (apparently you don't use flakes).
https://github.com/NixOS/nixpkgs/blob/c7ab75210cb8cb16ddd8f290755d9558edde7ee1/pkgs/by-name/si/signal-desktop-bin/signal-desktop.nix#L4
The overlay also works of course, but just updating the channel and nixos-rebuild should do it. Except when you have some mismatch of channel names or other weirdness going on that updating the channel doesn't land in your nixos-rebuild 🤷

You just need to nixos-rebuild --upgrade your system, apparently your #nixpkgs is out of date. #NixOS unstable and 25.05 are on the same signal-desktop versions, which is at least 7.64.0 and working.

That's the reason I eventually switched to :gitannex: to have more control. But it's by far not as convenient as syncthing in many regards.

I'm looking for a self-hostable #FOSS thing that I can throw the rest of my media library in the face (movies, music, downloaded youtube videos, etc.) and it'll sort everything nicely, maybe even query databases to find metadata and the like.

:nixos: #NixOS has made me like :bash: #bash. I use it so frequently with pkgs.writeShellApplication and have accepted to use its non-POSIX "advanced" features like (associative) arrays, the [[ ]] conditional syntax, the variable string mangling magic, etc. I absolutely love how writeShellApplication automatically runs everything through #shellCheck and makes it easy to set runtimeInputs and runtimeEnv. I'd love for it to pass the result through #shfmt though 😉

Oh, it was hard, yes! 😅 Both hardware and software side. Software is my part. But now that I have it in NixOS, the reproducibility and machine management make working on new features or such big structural reorganizations nicely incremental - and you know you can always go back, it's so soothing 😌

I spent the last two weeks migrating and curating all the :nixos: #NixOS configurations for the sensor packages to flakes. Previously, I hand-rolled the pinning, and it involved a lot of manual scripting, which is now gone, what a relief! 🥳
I had to drop :gitannex: #gitAnnex though for tracking assets I want to deploy on the copters. Unfortunately, flakes don't like git annex. 😔 But there is workarounds for many things.

I was using it on a weird Samba share where filesystem bullshit caused all kinds of problems, so I used an export. Sometimes you wonder why git thinks the tree is dirty, especially with unlocked files. But if you keep them locked I guess you won't have problems.

2025-06-24 07:12:16 GMT

- reply

Yes, other clients can also get stuff from exports. My general rule is: If you *can* use a normal git repo, do it. This is what works best and is most versatile. However:
- your TV player might not like symlinks (need unlock then)
- git will refuse to update the tree if for some reason the tree on the remote gets dirty. Even with receive.denyCurrentBranch=updateInstead. This is annoying and caused me to use exports. Exports can also track old versions now.

2025-06-23 17:07:36 GMT

- reply

As in it's the same physical storage behind both? Then you can just `git annex dead theDupeRemote` and if you want to be extra sure run `git annex fsck --from theRightRemote` (or before, never hurts). Then `git remote remove theDupeRemote` to never see it again (except when it was type=git autoenable=true 😉)
Or as you said, get everything from the dupe one, then dead it.

#borgBackup is amazing, indeed. For the regular restore check I'm not there yet to have it automated, but I already have a service that regularly checks if the actual list of backups have happened at the planned intervals and sends me an email if it doesn't.
Next up will be to actually restore some files from backups and check them.

OR make a git annex special remote for immich! Shouldn't be too hard as immich's api seems nice and apparently it hashes the files itself, so doesn't alter them I guess. Then git annex would sync directly with immich, possibly two-way, which would be awesome.

2025-06-18 02:17:51 GMT

- reply

I'm still pondering how to do it with my personal photos (did it for work first), which are also in git annex. I don't really see a direct possibility to keep it that way. My strategy would be:
- upload everything to immich (with immich-cli e.g.)
- set up storage template for a nicer folder structure
- add immich storage as special remote with importtree=yes and import from it
- rinse repeat?
Not very elegant though

2025-06-17 18:09:12 GMT

I have joined the #Immich cult and I am *very* impressed. :nixos: #NixOS made setup a breeze and it slurped 100GB of photos and videos like a champ while staying responsive. Facial recognition is amazing, a bit of manual merging and tagging is necessary, but that's expected. Also the keyword search works nicely - without you ever setting any 😁
For a workgroup that just wants to dump photos and search/tag later, I figured a single shared account works best.

I always thought the annex-cost is only to prioritise which remote to *download* a file from, not for things like locking or pushing order. 🤔

2025-06-17 06:58:14 GMT

- reply

Exactly, add --numcopies=1 to get rid of the locking for this one command. commenting the remote out in git config --edit could also help, but then your numcopies setting might prevent the move alltogether. Git annex tries very hard to not accidentally delete data, that's why it behaves lile this.

40k files should be ok. I would `git annex get` a bunch of files, tag them, `git annex add` them, then optionally commit, then do the next batch. 40k commits is not necessary.

Exactly. You wouldn't be in this situation otherwise, right 😉 Ideally, only add perfect static files you never want to touch.

No that's not what he means. He means put the tags into separate files. Use only a single player that by accident reads this one format. Not what you want.
If you really want the tags to be INSIDE the mp3 files, then the only thing you can do is retag and re-add. It would be cool if you could make a smudge filter that takes git-annex metadata (you'd put your tags there) and on the fly adds those to the mp3 upon checkout.

At least it doesn't while doing nix builds, e.g. rustdesk. Just tells you the crates, which doesn't really help estimate an ETA. If it has a progress bar, I guess they disable it in nix builds to not fuck up the terminal. Does it also have a simple percentage display?

Then, git annex won't ever put content there and will make sure anything gets off of it (if any and if there are enough copies elsewhere). A manual git annex move or copy will still put it there but the next sync/assist will remove it again.

#eMail #selfHosting gurus: I am looking for the simplest possible way to host myself a mailbox I can add to my email clients (Thunderbird, phone, etc.) as usual, so I can move mails there to free up space on the 3rd party "real" emails, then back them up separately on my server.
I do not want receiving or sending emails to work. Just an IMAP or whatever box I can shove emails in the face by dragging them in Thunderbird or with a script.
Ideally available in :nixos: #NixOS
#dovecot? 🤔

I have a ridiculous pile of keys on several rings, attached with a thin but long rope to my belt with a screw-lockable carabiner. Looks ridiculous and regularly destroys my pockets, but losing or dropping keys is one thing I never want to worry about ever again.
I also designed this #keyGuardian for #3dPrinting to organise keys others also need to use and force everyone to document who took which key:

#Krankenkasse⁣⁣n-Tipp: Patientenquittung beantragen. Bei der #TechnikerKrankenkasse sehr einfach über diesen Link:
https://www.tk.de/service/form/2006506/tkviabestellen.form
Dauert einen Tag, dann kommt ein PDF raus mit allen Behandlungen und Diagnosen, die man so hatte, chronologisch, mit Abrechnungsziffer (kann man nach suchen für mehr Infos) und Kosten.
Hilfreich, um z.B. einer #BerufsunfähigkeitsVersicherung zu beweisen, dass man bisher nichts Gravierendes hatte.
Oder einfach als Anamnese.

I take back all my rambling about :nixos: nix flakes. They are plain awesome:
· clear what input and outputs are
· easy updates of inputs
· everything is *much* faster due to evaluation caching
· easy reuse of other flakes
· nix shell/develop/run goodness
· ...

~/.config/Thunar/uca.xml, Thunar's custom actions config file, which I'm writing a module for:
https://gitlab.com/nobodyinperson/nixconfig/-/blob/main/modules/home-manager/thunar-custom-actions.nix?ref_type=heads
It always complains that it would `clobber the .bak file`, which I don't understand. But it is indeed a symlink / 'home-manager file', so that wording was probably wrong.

For its own files, yes, but if it needs to replace a non-home-manager file (which is sometimes necessary), it dies as described above.

2025-03-03 15:24:19 GMT

Same for me. One flake, home-manager NixOS module. I'd like my `nixos-rebuild ...` to just do it, and not require manual cleanup before or after.

2025-03-03 15:22:38 GMT

Sure that's possible, but wtf? At least provide an option to nuke backups or don't care about any existing files. Home-manager also stops the entire setup if one little thing fails, which can have very annoying consequences.

2025-03-03 15:10:18 GMT

Come on, #homeManager, you can do better than this... 😑
(no, not even `home-manager.backupFileExtension = "${toString args.self.lastModified}.bak"` helps, home-manager REFUSES to make backups like bak1, bak2, etc., causing the entire setup to stop and die unfinished.)

Many years I have tried building systems that allow me to declare #Thunar custom actions (contex menu entries), as those *really* don't want you to do that unfortunately.
From merging complex templates into the user config (1-2&image) to diving deeper with an entire #Python plugin system (3) I think the best solution is now #nix/#homeManager 🏠. Here (4) is my current approach.

Easily! 😉
`hellishly educational` is indeed a core #nix / #NixOS learning experience 😅 But I'm mostly past that pain now. #annextimelog says building this flake with all the customisations and auto-updating etc. took me ~35h in total. Still kinda many hours, but considering I'll reduce maintenance time drastically with this new system compared to the ever-breaking imperative distros, I consider it worth it.

Yeah I gotta clean it up and make it a separate public repo. Currently it's rather entangled with other experiments involving declaring private SSH keys and decrypting (un-password-ing) them interactively after login, so I can't open it up yet.

I yanked :manjaro: #Manjaro off of my mother's laptop and replaced it with a nicely customized :nixos: #NixOS.
She now has a button to pull config updates from my #homelab and build it (also done regularly in the background). Old versions stay selectable at boot.
When she has a problem, there's shortcuts for #RustDesk and ad-hoc reverse #SSH tunnels.
I can test everything in a VM, then add changes, she'll pick it up eventually or right away.
Loosely inspired by @npub1fgp…fhkc's #nixbook.

:nixos: #nix and #NixOS do HaaS: Hard-coding as a Service.
You tell it what you want your system to look like and it hard-codes the sh*t out of it.
This comes with all the benefits of hard-coding: Your environment, your PATH, manually installed software, etc. don't interfere with your base system at all. Every program and service sees exactly the dependencies and configurations they were given. The amount of power this gives for servers/embedded/purpose-built machines cannot be overstated!

Another day, another #3Dprint designed in #SolveSpace. This time it's a strain relief and dirt protection housing for a USB extender coupling.
BTW the USB cable on the left with the transparent plug costs 200€ (!). Manufacturers of measurement equipment for #meteorology sure know how to make money...

First time I managed to f*ck up :nixos: #NixOS so badly that I couldn't do anything anymore. I somehow made an ordering problem in systemd, causing nixos-rebuild --rollback to fail, systemctl edit <problemunit> also didn't help, I couldn't reboot (#systemd wouldn't let me, "resource deadlock prevented" or something), but luckily I had not `nixos-rebuild switch`ed but only `test`ed, so I could still power-cycle the machine to boot back into a working generation 🙃

No 24.11. But it sure feels that way. If I do nix-shell -p datalad, no build&test, but might just be because this one was cached locally. I wish there was a --explain flag that concisely runs down why exactly something is built.

How does one specify the private host ssh key with :nixos: #NixOS?
- putting in nix store is no-go (publicly readable for all users)
- secret management tools like agenix (and sops-nix?) have a bootstrapping problem: they themselves need the secret ssh host key to decrypt all the secrets.
So how does one then bring up a VM or a new fresh installation? How to specify the user passwordfiles then? This was a major roadbump during my last NixOS install on my laptop.

Oh I very well think so. They wouldn't do this if it didn't make them more money. Probably this is an A/B test where they want to find out what keeps users watching longer. Language barriers keep people from watching videos and as long as they don't lose more views from annoyed users like us than they gain views from people who didn't understand the language before, they'll keep it.

That's where we circulate back to the it-does-not-work-with-flakes part 😃
For unlocked files, it puts the useless relative symlink into the nix store or something like that and for unlocked files it only puts the placeholder files. Both equally unhelpful.
I think you can get nix to interpret a path as absolute to that one repo and not put it into the nix store, but that is very dirty.
Someone mentioned it working when the tree is dirty. Also doesn't feel right.

The fetcher would be less convenient. I want annexed files to work the same as any other file. I'm fine with making sure they are present manually, I mostly `git annex assist` anyway to commit and sync. Having to use a fetcher to fetch a file that's present right there just feels wrong.
