James Bond movies
James Bond: Do you expect me to talk? Auric Goldfinger: No, Mr. Bond, I expect you to die! James Bond I’m a big James Bond fan, so naturally I went to watch the new Bond movie Spectre which – spoiler alert! – is pretty bad. It also got me to reminice about the good Bond films of the past. My personal candidate for worst Bond film is Die An...

German Temperature Data
Temperatures Personally, I thrive in cooler weather. In fact, any temperature above 20°C is summer for me, and anything above 25°C is hot.

IP string to integer conversion with Rcpp
IP address conversion At work I recently had to match data on IP addresses and some fuzzy timestamp matching – a mess, to say the least.

Storing IPs as i...

Build your own offshore company
Hackathons are not alike Recently, a number of this blog’s authors were at a data hackathon, the strangest one we’ve been to so far.
