While the disposable cards might not always work, you can always create a regular virtual card and delete/freeze it afterwards. Not sure if there are any limits tho

Not really the same thing, but Revolut has disposable virtual cards that you can use (but it’s a full-fledged bank).

Some apps like MBWay in Portugal also allow you to create these virtual cards, but it requires a Portuguese bank account.

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’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.

I’ve been using Restic for a while, and it’s backing up to a Hetzner storage box (1TB).

Restic supports encryption, compression, deduplication, and can forget old backups in a spread out timeline (configurable; e.g. save one yearly, three monthly and 7 daily).

On top of this I also use healthchecks.io to make sure all backups are working.
