The ever-plummeting chances of a PhD finding a faculty job:
Since 1982, almost 800,000 PhDs were awarded in science and engineering fields, whereas only about 100,000 academic faculty positions were created in those fields within the same time frame. The number of S&E PhDs awarded annually has also increased over this time frame, from ~19,000 in 1982 to ~36,000 in 2011. The number of faculty positions created each year, however, has not changed, with roughly 3,000 new positions created annually.(via Javier Omar Garcia)

‘A Ruby gem providing “time travel” and “time freezing” capabilities, making it dead simple to test time-dependent code. It provides a unified method to mock Time.now, Date.today, and DateTime.now in a single call.’ This is about the nicest mock-time library I’ve found so far. (via Ben)
this is brilliant
