Installing LaTeX packages (sty, cls) - TexLive

See the URL.

A problem you may encounter:

[LaTeX output]
! LaTeX Error: Two \LoadClass commands.
[Type 'h']
You may only use one \LoadClass in a class file

You may be trying to do a \usepackage{class} when you should be using the package on the documentclass level e.g.

\documentclass[a4paper,11pt,titlepage,draft]{thesis}

C# Global Variables

Everything must be defined in a class. Gone are the days of including header files.

Abstract Class vs Interface

If you know your classes will need to interact with other classes whose design may change, an interface is the way to go.

If you need to include some "base-level" or default behaviour (e.g. communications handling) in your class template then an abstract class allows you to do so.

Additionally, in C#, implementation of multiple interfaces is allowed, while multiple inheritance of base classes is not.

sshd server key refused authentication error

Key refused errors generally refer to permissions being incorrectly set on the public key files stored in the user's home directory (generally residing on the server running sshd.)

e.g. the sshd daemon may require the authorized_keys or authorized_keys2 file to be set to 600 or 700 permissions..
