For anyone reading this who is unfamiliar with Debian’s release process, the Testing distribution is not a release. Rather, it is a holding area for packages that may eventually become part of a release.

Some people choose to run it instead of Debian Stable in order to get more recent non-security updates to packages, with the understanding that occasional breakage is normal for Testing.

The right answer is definitely not landfill.

Most people use their computers to run a web browser, maybe a word processor or media player, and… not much else. Even someone who has only used Windows can figure out those basics on a Linux desktop.

If the charities are unable/unwilling to provide support for Linux, they could give computers away on Craigslist before dumping more e-waste into our environment.

Doesn’t Apple Contacts support CardDAV natively? These sites say it does:

I’ll never be happy about almost every smartphone user I know happily putting my personal details into their phone, which then sends them to the likes of Google, Apple, and Facebook.

I de-googled my phone and sync my contacts to a trustworthy server. I hope this will eventually be easy for everyone.
