I just want to use the opportunity to direct the valued readers of this blog to the Wikipedia entry regarding holes. There are always too many where you don't need any, and when you desperately need them they are not there. Be wise and keep some Portable Holes in stock.

1st time on the berg

I was at the berg for the first time in my life... and I had a sausage roll with mustard, not with Ketshup.

< I played around with IPSEC today, it's quite some fun after you have found out all the rough edges :-). But now, hooray, ipsec between the windows-notebook and one linux-machine.

golden cone

Where I live, some prehistoric golden-cone has been found few years ago which gave one of the trails it's name: „Goldkegelweg“ (golden-cone hike).

Very bad code.

Just had a look at legacy code that spans several pages in this style:

 DO 13 K = 1,N
    Z(6) = U(K,I)
    U(K,I) = Z(5) * Z(6) - Z(4) * U(K,J)
    U(K,J) = Z(4) * Z(6) + Z(5) * U(K,J)
    IF(K .EQ. I .OR. K .EQ. J) GOTO 13
    H(I,K) = Z(5) * H(K,I) - Z(4) * H(K,J)
    H(J,K) = Z(4) * H(K,I) + Z(5) * H(K,J)
    H(K,I) = H(I,K)
    H(K,J) = H(J,K)

All variables have 1 or two characters and it is full of magic constants and meaningless array indices.
