Disconnect from campus WiFi when possible. When not, stick to the Brown Guest SSID with MAC randomization. Always use a VPN. For swipe cards, tailgate into buildings. Brown's building access is so restrictive, and the experience of

Hah, great account name! [0] Brown's security camera surveillance is about twenty years in the making. [1] There were student complaints as it was initially expanded, but it's long since faded into being just another part of cam

I'm not positive that they are. This post has already spawned one FERPA request, so I guess we'll find out! I think the chances are good. If Brown is using IT records to determine academic standing, they're very much academic

Ah, sorry, I didn't mean to take a conspiratorial tone. On campus, a LOT of students (perhaps the less technically adept ones) found it very surprising that Brown claimed to know where students were. This post was aimed primarily at t

Putting on my tinfoil hat, I'll note that mobile providers depends on Brown University for antenna space on at least three tall campus buildings.
