Backing up Android and Apps for an Upgrade

From time to time, a software upgrade is is needed. A upgrade - in contrast to an update - is a more invasive way to install a new version: Everything is deleted and installed from ground up. This is required e.g. when you want to upgrade from LineageOS 17 to LineageOS 18, like I recently did for a Fairphone 2 phone.


Code signing with let's encrypt certificate for your github pages domain

If you want to sign your code, you need a certificate. You can create a self-signed certificate, but then the users still need to accept your signature. Code signing is often used for eclipse and eclipse plugins. If you install a eclipse plugin, which is not signed, you always need to say “Install anyway…”. If your plugin would be signed - especially with a certificate that is trusted - this dialog wouldn’t show and the plugin is installed without notice.
