<title>Choosing Your Desktop Linux Distribution</title>

<description>Not all Linux distributions are created equal. When choosing a Linux distribution, there are several things you need to keep in mind.
Release cycle You should choose a distribution which stays close to the stable upstream software releases, typically rolling release distributions. This is because frozen release cycle distributions often dont update package versions and fall behind on security updates.
For frozen distributions, package maintainers are expected to backport patches to fix vulnerabilities (Debian is one such example) rather than bump the software to the “next version” released by the upstream developer.</description>

<title>Choosing Your Desktop Linux Distribution</title>

<description>Not all Linux distributions are created equal. When choosing a Linux distribution, there are several things you need to keep in mind.
Release cycle You should choose a distribution which stays close to the stable upstream software releases, typically rolling release distributions. This is because frozen release cycle distributions often dont update package versions and fall behind on security updates.
For frozen distributions, package maintainers are expected to backport patches to fix vulnerabilities (Debian is one such example) rather than bump the software to the “next version” released by the upstream developer.</description>

SSH keys are more robust since theyre cryptographically sane by default, and are therefore resilient to most bruteforce atacks. Theyre also easier to manage while enabling a form of decentralized authentication (its easy and painless to revoke them). So, whats the next step? And more exactly, why would one need something even better?
Why?
