Hope everyone's well, haven't been around much as I'm very busy getting my head done in by the PhD study. Today I was trying to figure out how to convolve two functions which each integrate a Gaussian Process with different covariance. Needless to say, I didn't figure, convolve, or Gaussian Process, although I suspect I may have integrated something. I'm just not sure what.
Anyhow, weirdness today, other than mathematical: I received a parcel notice in the post the other day, which I thought was odd as I hadn't ordered anything. Picked up the parcel today, and it contains two copies of Frederick Forsyth's new book, The Afghan. Signed.
Now, I haven't read anything by Frederick Forsyth since Day of the Jackel when I was about 16, so I'm fairly sure I didn't order two signed copies. There was nothing else in the padded envelope, and nothing on the outside except a postmark indicating that the package was posted in London.
WTF?
