How much Hard disk space you should allocate to Time Machine on your MAC is one of those tough ones because it depends on two really big questions:

1. How much CAN you afford to allocate to Time Machine?
2. How long do you want time machine to keep your changes?

Here some help deciding...

Mac users who have used PCs in the past often think that upgrading your HDD (like changing to an SDD) means re-installing the disk. This is not the case, Apple Mac OS X will happily be cloned to another HDD. On a PC with windows, it is posible to simply clone the HDD but it's not recommended and anyway, usually if you went to the trouble to upgrade your hard disk you would also take the trouble to fix the bloated windows system with a system re-intstall. Yet another reason why MAC's save you time (and therefor money).

Heres how to clone you hard disk on a MAC.

Red dots and screen problems

Are you getting red dots on your screen? They could be flickering red dots randomly appearing or whole screens worth of red pixels in some kind of random pattern. Here's how to troubleshoot this problem

Before we start. If you are looking for a solution to the problem of single black pixels in a particular place whenever there is a white or light background, these are dead pixels and there is probably not much you can do about them. If you have more than 4 or 5 and are under warranty, take it back. If not you'll probably have to live with them.

I found Joomla and Joomfish language packs caused many errors related to using the wrong pack when I was new to Joomla. One thing that’s always hard when you come across something new is jargon. It can get really confusing when different things which can seem somewhat similar (and may in fact be related) use similar words. Here is some clarification about Joomla and Joomfish language packs.

If the domain you enter into Google Analytics is different than where the Joomla site actually resides, you may need to alter the Google Analytics code to make it work.
