Aha, the first full day of the first week of work; now back from vacation. Now, I can start learning DMRG!
Err...what's this? The postdoc, Stefan, that I'm supposed to be learning from with various questions just got a job at a software company on his vacation! He's going to leave very shortly! Wow! Congratulations!
Hmm, I guess that means my time table must be moved up...better get to it.
