Google Technical Events Blog
Google has presence in many technical events, from academic conferences to hackathons, developer conferences and others, and their presence is of interest to the global technical and academic community. For example, this should be of interest to graduate students looking for travel support, meeting Engineers and Researchers from Google, or pursuing jobs, etc. There is a nice blog that shows both upcoming events as well as commentary on events with Google presence. Enjoy!! (I learned about the mobility data contest from this blog).
