Privacy Policy

This page lists privacy issues concerning this site.


The wiki uses a cookie that doesn’t identify individual users. The cookie is used to remember your preferences from one visit to the next. If you examine the cookie, you need to split it along the URL-encoded 0x1e byte (%251e). A typical user’s cookie might contain username AlexSchroeder, for example. This says which username you’d like to use when editing a page.


Nothing requires usernames to be unique. You can pick any valid page name. If you do provide a username, we’re going to store it in various places:

  1. our log files for Recent Changes
  2. any page you edit for the little note at the bottom saying who last edited it
  3. the “keep” pages which are used for the page history (follow the View other revisions link at the bottom of a regular page)

Information on this site is available via the HTML pages, RSS feeds, Atom feeds, Finger, Gopher, and Gemini.


Offline backups of the data exists and will be overwritten at irregular intervals.

Tracking of IP numbers of readers by the wiki

In order to prevent leeching, the wiki also keeps track of the IP numbers that have visited the site in the last twenty seconds. The visitors.log file lists IP numbers and timestamps as follows: 1390729057 1390728798 1390728798 1390728798 1390728797 1390670644 1390670381 1390670381 1390670380 1390670380

This is updated whenever somebody visits the site. This information is not public.

Tracking of IP numbers of authors by the wiki

The wiki also tracks IP numbers whenever a page is edited. The idea is that we want to ban certain people from editing the site via BannedHosts. This information is available in multiple places.

After four days the IP number will be removed from our wiki log files by the maintenance job.

Recent changes records IP number of authors. If you check Recent Changes, you’ll see that we’re translating IP numbers of anonymous edits into a colour code. We’re using a hash function to turn the IP number into an 32bit number, convert it to octal, take the first four digits and show one of eight colours for each one.

Web Server Logs

The web server itself also keeps access log and error logs. These go back four days.

Thank you.

These are blocked in my browser anyway, but it is good to know that I don’t have to fight against the website :)
