exim: select smarthost according to sender address

When sending mails from my systems, I usually want to use different smarthosts according to the sender address. If I use the sender address, I want the mail to be delivered via, if I use one of my addresses, I want to use the smarthost at Manitu and so on. With exim, this is possible with a few configuration adaptions.

First create a file named /etc/exim/smarthosts that will contain the routing information. The contents look like this:

Laptop Maintenance Mode for Gentoo Linux

I run Gentoo Linux on a variety of laptops, and while I'm generally happy with it, there are some places where the default system just doesn't fit my needs. Sometimes you can just feel how parts of the software were designed for 24/7 servers and not for mobile devices. For example, there are some processes that need to be run frequently, but that you really don't want to kick in when you're out in the field and running on battery power - updatedb, makewhatis or Leafnode's texpire for example. And there are some other maintenance actions that should be performed on a regular basis, too - emerge --sync and backup for example. And most of the time, I just don't feel inclined to manually perform all these tasks when retuning home after a working day. This is why I added a "maintenance mode" to my laptop installations. Usage of this maintenance mode is very straight forward - plug the laptop into the local network, power it on, select "maintenance mode" in the boot loader menu and go away. The system will automatically perform all actions and then power down.

MDD meets ABAP

MDD is a hot topic for some time now. With the arrival of powerful tools like EMF an oAW, it's become possible to actually use the benefits of model-driven development without spending too much time and money on the tools. MDD has long reached it's break-even point between intellectual investment and development speed-up for certain types of projects. It's not the solution to all problems, but it's a really powerful technique with a set of stable and proven tools available.

Why I enjoy ABAP development (2)

In the first article, I already mentioned some of the aspects that make ABAP one of my favorite development environments: the central data dictionary and its connections with the language and runtime system, database access and the change and transport system. In this article, I'll tell you a bit about what you may or may not have to consider when developing ABAP programs.

Why I enjoy ABAP development

It was another one of these déja-vu experiences. At the Eclipse Modeling Stammtisch yesterday, I mentioned that Eclipse is more or less a hobby of mine. I did (and still do, if I can spare the time) SAP R/3 development for a living. Yep, that's right: ABAP. And I actually enjoy it. Now you can imagine the expressions of the average IT guy - varying from astonishment to disbelief or even disgust. ABAP - how could you come to like that?

The Old Rambler

A small Irish (?) tune, found somewhere in my files and edited for acoustic guitar (including notation and tabs).

RCP Introductory Workshop

This is the handout for an introductory workshop on the Eclipse Rich Client Platform (RCP). For now, the document is available in German only.

MDA / MDSE for SAP R/3 Development Projects

This article used to contain the slides of my presentation held at the Special Interest Group Model-Driven Software Engineering (SIG-MDSE) on May 30th of 2008. I've created these slides using the Siemens Corporate Design, but I am no longer with Siemens. In order to avoid trouble, I have removed the slides - if you're interested in the contents, please contact me.
