Jet lag has hit me with the full force of a torrent of bricks, although I suspect that last month's overexercise of my mind and sleep deprivation is the real cause here. Whatever the reason, I'm seriously underclocked, spent almost all hours sleeping, and lost count of days. I'm gradually recovering despite the 31C heat (i.e. nearly 90F); hopefully I'll return to some semblance of working condition this week...
