The story ended up on the front page of Digg, stayed there for nearly 12 hours and was picked up by a bunch of secondary sources, resulting in 100,000 Visitors within a day (most of them within the first 12 hours). Trying to keep my server up and alive, I learned a lot about what it takes to keep the server alive, hence I decided to slide a non photography related post in, hopefully giving everyone who finds themselves in a similar situation some points to consider.

rrdtool (round robin database tool) by Tobi Oetiker is a small database and graphing tool for many kinds of data. If you know, mrtg, you´ll have an idea of what its output may look like; just think of rrdtool as far more flexible (and thus a good deal more complex ;). On this page, I have put up some snippets that I used in the past to create graphs about different kinds of data. They´re provided as-is -- i.e. you might have some work to do before they work exactly the way you want them to.
