Unison & multiple hosts: “Warning: inconsistent state.”

As some of you might know, Unison is this great tool that allows bidirectional synchronisation of two hosts, – no matter which operating system they’re running… Well, at least the well known ones are supported.

Since Unison can also be used to sychronise more than two hosts, it’s perfect for big amounts of data that has to be shared in a team.

A scenario like this is possible and works for me: UserA <-> Server <-> UserB.
But of course, also other users could sync with the server. Unison rocks!

Today, after reinstalling his OS, my friend got the following error message:

GCALDaemon deb-package for Ubuntu/Kubuntu

GCALDaemon is a great tool to synchronize many of Google’s services such as Google Calendar and Contacts with your local PC. Unfortunately, the installation on Ubuntu/Kubuntu and any other Linux distribution is still not the most comfortable. For this reason, I sat down some hours and packed the tool into a deb-package and additionally added a nice command line tool to simplify some of the basics.

Excel: Add weekdays to date (VBA)

Since many companies work with Microsoft Excel it is often necessary to be inventive in order to implement the required functionality in your worksheet.

In some applications you might want to calculate a deadline date within the week, e.g. to make sure that a product or service will be delivered within a time frame of max. 10 working days.

Launch Nautilus in the current working directory

Working on the console is sometimes tiring, especially when you have to rename files. Using Nautilus is much quicker for these types of actions. The problem is, that if you’re working in a deep depth of your file tree and your path is very long, it may take you some extra seconds to open this path in the Nautilus browser. So wouldn’t it be much easier to simply type naut on the console to open Nautilus with the current working directory?

Unison 2.27.57 on Debian Etch and Ubuntu Hardy

The good thing about the file sync tool Unison is, that it’s available for several operating systems. This is great for groups working on different systems (Mac, Linux and Windows) but want to share and synchronize files on a remote server.

Well, the bad thing about Unison on the other hand is, that its backwards compatibility is anything but great, so that you have to make sure that everybody in the team uses the same version. And this can be tricky depending on what system you are using.

My home system is Ubuntu Hardy, the remote server system is Debian Etch. Both come with Unison 2.16.13 which would be great if not Apple’s new Leopard brings the newest version 2.27.57. Long story short, I needed the newest version on Hardy and Etch.

Roundcube login via PHP script

Roundcube is an AJAX/PHP based e-mail application which is really flexible and easy to use in comparison to other free web based solutions.

For the customer interface of Silversun, I wanted to use RC as the internal web mail application and therefore had to embed it into my system. To avoid that the customer has to log in twice (customer interface and Roundcube), I had to simulate the login request with a PHP script.

Switch off sound on Ubuntu before login

Most of the Ubuntu users know the situation: You’re sitting in a public place, let’s say a lecture or a cafĂ©, and you forgot to switch off the sound of your laptop. Unfortunately, you can’t avoid the first short drumming. But by using the following command, it is at least possible to switch off the longer welcome melody of Ubuntu before you actually log in.

Hello world!

Hello world!

This is supposed to be my own web log. I’m not really sure if I have many things to share with the world, but I’m going to try my best to come up with some useful things. I guess most of them will have to do with Silversun and/or Linux problems and solutions.

For those of you who’d like to know more about me, please visit my Xing Profile or my private web site.

Thanks for your attention ;)
