Deflattred

The idea of Flattr is nice, but they have one problem: They don't have good peerings for hosting their API and even worse, their DNS is slow as hell.

While their performance in Europe is ok, it's poor in the US, so I deflattred until they've fixed that.

Before:

After:

Nasty Bug in Ubuntu 10.04 TeX Live Listings Package

Since upgrading to Ubuntu 10.04, changing counters in listings packages isn't possible anymore (worked perfectly with 8.04, 9.04, 9.10).

The Ubuntu folks don't seem to care a lot (Bug #573653), does anyone have an idea how to fix this? Please send me an email.

Update

A solution/workaround seems to be this:

\lstset{
  numberbychapter=false,
}
