It's summertime in Silicon Valley (ah, the sweet image of poolside geeks, roasting in oil while wearing Snapchat specs and Star Wars arm floaties). Still, the tech news keeps right on coming. Russia stayed in the headlines, as the US set up a new task force to fight Russian election interference and Putin & Co. threatened Google for promoting "illegal mass events" on YouTube.
