One thing I did not learn at the language school in Arequipa is computing vocabulary. But for my work here in Lima, I need quite some of that. So I have been digging at bit for vocabulary lists.
PONS has a list of new vocabulary (German/Spanish) which includes a lot of computing speech. For example recently some blog-related words have been added. Yo soy un bitacorero, I am a Blogger.
Apart from that I usually look over at DIX, a German-Spanish dictionary.
