I'm building a socket application that need to shuffle a lot of small/medium sized files, something like 5-100kb sized files to a lot of different clients (sort of like a web server, but still not quite).

I've been checking out using a system called ROS ( http://www.ros.org ) for some work.
There are lots of different types of data that get sent between network nodes in ROS. You define a struct of data that you want to send in a message, and ROS will handle...

I do not know the specifics of ROS but in networking it comes down to the following constraints:
Distance: speed of light is fast but over a distance it starts making a difference
Protocol Overhead: connection oriented vs .
It depends.

These can hold as much data as TEXT and NTEXT respectively which will be deprecated in the future .
In SQL Server 2005 onwards, you can use VARCHAR(MAX) (or NVARCHAR(MAX) for unicode) .

I need to perform a complicated calculation. In my case it seemed most natural to create a Calculator class (abstracted using a strategy pattern).

To fetch specific columns from a table, rather than all (*) use this:
->from(array('r' => 'recipes'), array('id', 'title', 'method'))
or
->joinLeft(array('rp' => 'recipe_pictures'), 'r.id... .
Use joinLeft instead of join to produce left joins.

My computer has become awfully slow lately. I suspect that there might be some problems with my hard drive as every time it hangs, it works its ass off.. Do you have any suggestions for how to determine if the problem is related to the hard drive?
