As is traditional, I have not tried it, however ...

GNU source-highlight offers a LaTeX output mode (-f latexcolor) and it
has a mode for highlighting patches (-s diff) so you could probably
combine those together to get what you want.

By the way, I found "UNIX Internals: The New Frontiers" by Uresh Vahalia
to be the most instructive text on the workings of virtual memory
across multiple OSes. May be a little outdated on implementation details
but the theory hasn't changed much in the last 30 years (and being a
1996 publication, it doesn't include that young whipper snapper Linux.)

Thunderbird problem

Hello,
   I do not use Thunderbird or Microsoft, but I have just been asked about a
problem using Thunderbird on Microsoft. An email arrived with reply-to
address different from the originating address, but while typing it in on
the reply, as soon as the  <at>  was entered the entire line turned red and it
would not send until the new address was entered into the address book. Is
there a correct way to do it?  Thanks.

I don't use those products either. My response to questions about them
is "I don't use those. I expect that if you click on the Help option
from the menu there will be an option for getting in contact with those
responsible for the product".

I don't use Windows but I do use Thunderbird.  I'm puzzled by your problem.

If the email has a reply-to address, why is your friend trying to type 
the address in?  Just hit "Reply" and any decent MUA will use the 
reply-to address correctly.

Thunderbird displays addresses which it doesn't know in red, but it 
doesn't stop you sending to them.

   Thanks for the reply, I will pass it on. The person who asked has been
trying to wean people away from total Microsoft and was trying to provide
help. He had not found an answer via Google, I have never seen the problem,
could not find Thunderbird running here, and was just going out, so I asked
here.

We use and support TB extensively on Windows and Linux, and agree 
completely with the above.

Talking dictionary for Linux

Guys

A severely dyslexic friend of mine needs her laptop overhauled.  She's keen to try Linux but the one piece of
software she must have is a talking dictionary.  Anyone know of a talking dictionary being available for linux?

   There is speech software available for at least Debian, and Klaus Knopper
even produces a CD called Adriane-Knoppix specifically for blind users,
named after his wife who is blind.
