I thought it was a problem with my phone since I'm using a custom ROM and it did not happen before. When I open Firefox and it has been in the background for a while, it shows a black screen where the web content should be and often crashes if you try to open another tab or do something else. Also happens if I open a link from another app. The only solution is to close Firefox and swipe it off the recent apps and reopen it. Is this the same problem you have?

That's great to hear! There are still some apps on my phone that aren't taking advantage of it then -- or perhaps it has something to do with my custom ROM.

I'm unsure if this is still the case in the latest Android versions, but the terrible camera APIs in 3rd party apps/social media apps is still a big reason why my non-techy friends switched to an iPhone. Even if the quality of pictures using the stock camera app is good, if the photos that come out while using Instagram or Snapchat or whatever kids are using these days are low-quality, they'll consider moving to an iPhone. Again, I'm unsure if the APIs already exist or if it's just app developers that are not using them. Either way, there needs to be a push in this direction.

I personally use Firefly-III. It is completely self-hosted (there is no cloud version that I know of), and is quite feature-complete. Their data importer allows you to import transactions directly from your bank (check if you bank is supported, but all European banks are), so you don't need to create anything manually.

For example, I have the data importer running daily, and then I only have to set the correct category for each transaction, which doesn't take that long.

I'm in the process of migrating my servers to NixOS. It takes a lot of time and the learning curve is steep, but I have one config shared for all the servers and PCs. I have setup the servers to automatically pull the latest configuration everyday and even restart if there's a kernel update.

This means I just need to update my laptop and push the changes to the repository, and all the servers will also update.

I haven't had this setup long enough to know if things will break unexpectedly with updates tho. NixOS has a great feature where you can rollback to a previous configuration (generation) with a single command. You can always keep using containers to isolate updates, if you want (Nix allows you to declare those in the config as well).

As an example, you can take a look at my config.

EDIT: Systemd timers have an option to randomize the time a service runs, I use it all the time. The option for Nix's config pulling is using systemd timers, so you can use that.
