Following Enrico's terminal-emulators comparison, I wanted to implement "start a new terminal tab in my current working directory" for rxvt-unicode aka urxvt. As Enrico notes, this functionality is something between "rather fragile" and non-existing, so I went to implement it myself. Martin Pohlack had the right hint, so here's the patch:

On RedHat/CentOS/rpm systems, there's no dpkg --compare-versions available - sort -V can help to compare version numbers:

Yesterday saw the first beta release of the new PostgreSQL version 9.4. Along with the sources, we uploaded binary packages to Debian experimental and apt.postgresql.org, so there's now packages ready to be tested on Debian wheezy, squeeze, testing/unstable, and Ubuntu trusty, saucy, precise, and lucid.
If you are using one of the release distributions of Debian or Ubuntu, add this to your /etc/apt/sources.list.d/pgdg.list to have 9.4 available:
deb http://apt.postgresql.org/pub/repos/apt/ codename-pgdg main 9.4
On Debian jessie and sid, install the packages from experimental.
Happy testing!
Over the past few weeks, new distributions have been added on apt.postgresql.org: Ubuntu 13.10 codenamed "saucy" and the upcoming Ubuntu LTS release 14.04 codenamed "trusty".
Adding non-LTS releases for the benefit of developers using PostgreSQL on their notebooks and desktop machines has been a frequently requested item since we created the repository. I had some qualms about targeting a new Ubuntu release every 6 months, but with having automated more and more parts of the repository infrastructure, and the bootstrapping process now being painless, the distributions are now available for use. Technically, trusty started as empty, so it hasn't all packages yet, but of course all the PostgreSQL server packages are there, along with pgAdmin. Saucy started as a copy of precise (12.04) so it has all packages. Not all packages have been rebuilt for saucy, but the precise packages included (you can tell by the version number ending in .pgdg12.4+12 or .pgdg13.10+1) will work, unless apt complains about dependency problems. I have rebuilt the packages needing it I was aware about (most notably the postgresql-plperl packages) - if you spot problems, please let us know on the mailing list.
Needless to say, last week's PostgreSQL server updates are already included in the repository.
More and more packages are getting autopkgtest aka DEP-8 testsuites these days. Thanks to Antonio Terceiro, there is ci.debian.net" running the tests.
Last weekend, I've added a "CI" column on DDPO that shows the current test results for your packages. Enjoy, and add tests to your packages!
