Moving away from the general theme of depression and existential angst, I'd like to report a (however partial) small success: I'm posting this from my desktop computer, without the need for it to "piggy-back" on my laptop's wireless connection.

There's a slight catch, though: I'm having to do it roughly the same way I did it on Ubuntu: install ndiswrapper, set up the Windows driver for my Netgear WN111 USB wireless dongle through ndiswrapper, and hope for the best. It...

Introduction

OpenSSH is a daemon (a "service" in Unix environments) which helps system administrators to manage server remotely.
