Smithsonian magazine is comparing computer pioneer Jaron Lanier – one of the people who, indirectly, made what you’re reading (and the way you’re reading it) possible – to a Cold War double agent. Because he’s turned against the web he helped create:

The aptly named ExtremeTech BLOWS THE LID off connection speeds with the HEAD-SPINNING news that American and Israeli researchers have sent 2.5 terabits of data per second through the airwaves:

These twisted signals use orbital angular momentum (OAM) to cram much more data into a single stream. In current state-of-the-art transmission protocols (WiFi, LTE, COFDM), we only modulate the spin [...]

MIT’s Technology Review is not a publication ordinarily given to hyperbole. So it’s a little distracting when their web desk declares that Facebook is heading for an implosion that will take internet business as we know it down with it:

The daily and stubborn reality for everybody building businesses on the strength of Web advertising is that the value [...]
