I usually get annoyed by spam robots. They are able nowadays to even bypass captchas. So what helps? I recently read an article saying that scientists work on a new kind of spam filters that can identify spam by the way the actual text looks like. That raised an idea in my head. Why not just count the number of links that a new guestbook entry contains? Usually this is what they do at my guestbook. They leave dozens of links. So I added a simple count in my guestbook plugin. Whenever there are too many links, I just ignore the entry. 🙂
My current job often challenge me with various country codes and timezones. So I prepared two lists providing you with this information. country_codes.csv list all country codes (ICAO, ISO 2-letter, ISO 3-letter, ISO 3-digit), country names and continents. timezones.csv will list the ISO 2-letter code together with country name and Unix Timezone. Both lists might not be complete. So if you find errors or omissions, just let me know.
