AVG is better.
I had Avast and found that it didn't fully scan my comp.
Then I decided to install Avira. It scanned, but it didn't seem to be doing anything. Half the time I would have to wake it up.

Microsoft Security Essentials is better

Oh yeah, its super slow but it works.

add ons are under tools in "extensions"
also Google chrome has a spell checker

LaTeX should definately be considered to be put on.

It is basically a program for writing documents like Microsoft Word or OpenOffice.org Writer, however you write in simple code, which allows for adding unusual layouts or specialised character in a far faster way that Word. You are also less bothered with trying to drag an illustration to just the right spot. It also performs better when you are writing long documents, when Word always has a nasty tendency to slow down considerably. To be fair, LaTeX does not compile into easily readible text automatically, like Word, you have to build your tex file to get a PDF file for instance, but building goes fast and it is very nice to get more control over what you're writing. It takes a few hours to be able to work with it to an acceptable degree, but especially if you are considering studying science, it's a definite recommendation.

You can find the download page here. There are versions for Linux, Mac and Windows.

A typical tex file will roughly look like this:



An amazing file has been written by Mr Pakin including nearly 6000 LaTeX character (some of which are include multiple times, for a reason, though). You can find it here.

LaTeX can be intimidating at first, but it quickly becomes very, very rewarding.

Also, no latex jokes, please. They get old very fast.

If you're going to include that, why not include emacs as well?

Would anyone be so kind as to post recommended frame-rate and such for Camtasia? Anything I try seems to turn out wrong.
