new-in-testing

Finding what was new in testing today

I played too much with sources.list and aptitude lost track of what packages are new and what was already in the system.

The place to recover this kind of information is the debian-testing-changes mailing list archive: new packages are those that say "(not in testing)" in the "previous" column.

Thank you dato for pointing me at it.

GPL and Business FAQ

I sometimes happen to be in a dialogue like this:

X: According to GPL, you can sell copies of your software at any price you want, right?

Me: Right.

X: But your customers can in turn sell copies of your software at any price they want, right?

Me: Right.

X: So, the only way a GPL developer can make money is by charge for development of their software?

procmailrc-trap

Procmailrc, TRAP and LASTFOLDER

I use procmail and lbdb.

lbdb is invoked at the beginning of procmailrc harvesting From: addresses from all incoming mail, so that they can later be queried with mutt. It's really neat.

However, if it's put at the beginning of procmailrc, it harvests From addresses from spam, too. This causes the ldbd databse to become very big, slow to query, and in some unlucky cases, to return lots of bad results.

Filtering Debian Packages file
pkgprune - Filter a Packages file

Usage: pkgprune Packages > Packages.filtered

Filters a Debian Packages file by removing either a list of packages (and
their reverse dependencies) or the packages that have given tags.

Dependencies in the filtered Packages file will still be satisfied.

Available via:

wget http://people.debian.org/~enrico/2007-08/pkgprune/pkgprune

or:

hg clone static-http://people.debian.org/~enrico/2007-08/pkgprune

The top of the script has a configuration section:
