Synchronizing OmniFocus via WebDAV on Gentoo Linux
The biggest new feature in [OmniFocus](http://www.omnigroup.com/applications/omnifocus) 1.5 will be the possibility to synchronize multiple OmniFocus to one single database.
This is very nice as, I suppose, a lot of people have multiple installations of OmniFocus and keeping all of them up to date is a hassle. Especially now, as OmniFocus is also available for the iPhone a synchronization feature is an absolute must to keep doing GTD "stress-free".
There are several ways to set up the synchronization feature:
* **[MobileMe](http://me.com)** This is probably the most convenient way but it requires you to have a MobileMe account.
* **Bonjour** Synchronizing via Bonjour requires to make one Mac to function as a "database server" (which has to be up and running if you want to sync) and synchronizing is only possible over the local network.
* **Disk** If you have NAS system or a USB hard drive connected to your AirPort you could use this option. But unfortunately the iPhone does not support this way.
* **WebDAV** If you have access to a web server you could use that one as an OmniFocus database server. This way you have access to your tasks from all over the world.
In this tutorial I want to show you how you can configure an apache web server to support WebDAV and what you have to do to make OmniFocus use your very own "cloud".
Building PostgreSQL on Leopard
As you might know the [PostgreSQL Global Development Group](http://www.postgresql.org) is currently working on the final version of the PostgreSQL Database Management System (DBMS) 8.3 which has some nice features. Unfortunately, there is no prebuilt package available for Mac OS X of the current beta versions. But fortunately building PostgreSQL is very easy on Leopard:
Block Specific E-mail Addresses with Exim
Recently I was flooded with e-mails a friend sent me. Mails with PowerPoint or PDF attachments of hundreds of kilobytes with jokes. Although I told him to stop this he ignored me and continued sending me this crap.
I could create a rule in Mail.app which deletes such mails but that wouldn't help as the rule mechanism only works with received mails. But I don't even want to have to download them.
A better solution is to let the mail server (here [Exim](http://www.exim.org)) deny such mails while they are delivered.
Mounting Remote Computers Using MacFUSE and sshfs
With the Linux kernel version 2.6.14 a technology called FUSE was merged into the mainstream Linux kernel. FUSE stands for *Filesystem in Userspace* and it allows normal, non-privileged users to create their own filesystems.
Amit Singh (author of the book [Mac OS X Internals](http://www.osxbook.com)) ported this great technology to the Mac: MacFUSE.
So Long, and Thanks for All the Fish
After years of bleat-less serving my web pages and emails I had to shut down euklid forever.

Implementing Greylisting with Exim
Due to the increasing amount of annoying SPAM mails there exist many techniques to reduce that junk.
One very successful approach is called "[Greylisting](http://en.wikipedia.org/wiki/Greylisting)".
