Technical texts like this are relatively easy to get right. English is not my native language and when I was young I could read computer related stuff, but had trouble understanding, for example Harry Potter. If Google has an example of such a text, they can learn all the translations for all the technical terms from that data. However, a news article is much more difficult because they often have lot's of metaphors, etc. If you try to translate those, you get a lot of halve finished sentences and stuff like that.
