Hardening a credit card

When I get a new credit (or debit) card from a bank, I like to do a few things to strengthen its security, none of it ends up breaking my use cases or anything, but it could do so to you. So beware.

Pre-requisites

Do not ever use your physical card for online purchases or any form of purchase using its details, if you've done so, even for Google Pay, get a new one.
This guide assumes the card is brand new, as some stuff depends on certain details never being revealed, you can follow it anyway, but beware
Credit cards overall are not great at security, you can not confirm the value of the purchase before making one, for example.

Aplicando uma película

Já vi muitas recomendações esquisitas sobre como se deve aplicar uma película de celular, a maior mentira são os paninhos que vem com ela normalmente, eles sujam mais do que qualquer coisa.

Com isso em mente, vim dar minhas recomendações nisto para que não tenha nenhuma bolha ou mancha na tela ao aplicar.

Recursos

Pano microfibra (preferencialmente 2), como alternativa você pode usar toalhas de papel de cozinha

Troubleshooting issues with CalyxOS' flasher (command line)

This guide is meant to try and help with common issues when using the CalyxOS flasher. First of all, we will try to get your environment right. Be sure to follow the official instructions for your device, this is a different resource.

The flasher and docs usually recommend enabling USB debugging, in this case we will not, but you can anyway. USB debugging is used only for rebooting the device into bootloader/fastboot mode, instead of that, we will do this manually, as this step can cause issues.

Getting the device in bootloader/fastboot mode

After the preparation steps for your device, such as enabling OEM Unlocking, we will shut down the device and get into bootloader/fastboot mode.

Seedvault + Syncthing = ⁉️

I just tested using Seedvault with Syncthing and to me it feels like a great setup. I still need to configure it for all time use, but so far, first test seems like everything works fine. It allows me to use a connected service where my data isn't just one place, without needing physical things like a USB flash drive, etc, but without needing to pay for the cloud, and dealing with bad speeds, especially with something that can be as demanding as device backups.

Downsides

Your device essentially has half the storage, since you'll need to keep your backups inside your phone, so there's redundant data there.
This is not a fully tested setup, and you may lose data with it.

How to properly install android-tools in Fedora

Currently, it seems as if Fedora doesn't install udev-rules, to get this working, I've had to manually install them from a community project. I'm not very knowledgable in Linux, these are just the steps I had to do to get things working that I'd like to document.

Install android-tools

Install android-tools from DNF.

sudo dnf install android-tools
