This page is basically my blog. My interests wander mostly around math, statistics and software.

To ease the use of the product of this collaboration in other contexts, you can now use google-spreadsheet-csv to download and upload the CSV version of a sheet.

The last article in the "HD occupation series", Hard drive occupation prediction with R - Part 3, explores how we can use historical data and Monte Carlo simulations to predict the range of possible values for HD occupation at any point in the future.

After the Deadline is a English language checker used by Wordpress.com amon others. I have built a command-line client for it: the atdtool, with a Debian package available in the debian page.

The second article on the "HD occupation" series, Hard drive occupation prediction with R - Part 2, shows us where the linear regression breaks (hint: real life), and uses Monte Carlo simulations to build a more robust method.
