KTagebuch for KDE4

I am currently porting KTagebuch to KDE4. Saving, loading and browsing is already working.
For people who already want to try this version I created a Ubuntu package for KTagebuch-0.80. Please create a backup of your KTagebuch database which you can find in "~/.kde/share/apps/ktagebuch/", because this version has not been tested much.
I set up a github repository for the source code.

Notes about creating a project with Seam, Eclipse and Maven2

install JBoss, Seam und Eclipse (German): http://javathreads.de/2008/09/tutorial-mit-jboss-seam-und-jee5-unter-eclipse-starten/

I used the following versions: jboss-5.1.0.GA, jboss-seam-2.1.1, Eclipse 3.6M2

Maven Project Template: http://kasper.eobjects.dk/2009/04/seam-ejbs-and-ear-packaging-in-maven.html

1. Change sayHello in ejb-hello.xhtml to sayHello() (with the parentheses)
2. Change version of facelets dependency in web/pom.xml from 1.1.11 to 1.1.15.B1 to work with JBoss AS 5

Eclipse Maven Plugin: http://code.google.com/p/q4e/

Import project directory as Maven2 project (Seam-EJB-...) .

Eclipse File sync Plugin für Deployment http://andrei.gmxhome.de/filesync/index.html

Create configuration for Filesync:

Filename: packaging/.settings/de.loskutov.FileSync.prefs:

#Wed Oct 07 11:34:44 CEST 2009

useCurrentDateForDestinationFiles=false

Reading a CSV File with FasterCSV

I needed to import a data in a CSV file into a database. I needed to find the encoding of the CSV file. I found a method to display the encoding in the VIM statusline, and included this code in .vimrc:

# show file encoding in vim status line
if has("statusline")
 set statusline=%< %f\
%h%m%r%=%{\"[\".(&fenc==\"\"?&enc:&fenc).((exists(\"+bomb\")\ &&\
&bomb)?\",B\":\"\").\"]\ \"}%k\ %-14.(%l,%c%V%)\ %P
endif

The characterset was Latin1, and I converted it to unicode with Iconv. The row with umlauts had to be split manually, because FasterCSV did not split it.

FasterCSV.foreach(csv_file) do |row|
  if(row[1].nil?)
     row=row[0].split(',')
     Iconv.iconv('UTF-8', 'LATIN1',row[0]).join
     Iconv.iconv('UTF-8', 'LATIN1',row[1]).join
  end
end

Is there a more elegant solution?

RBDiary 1.1

This is a slightly improved version. The most visible improvement is the marking of the entries in the calendar.

RBDiary – 1.0

RBDiary - 1.0 another attempt at at diary application. This time I used Ruby and plain QT which means it is cross platform and works on all three OSs. I wrote it in a few hours and it already does everything I need. With KTagebuch it was completely different. I spent many hours just struggling with the automake build tool.

AnimalTracker 0.72

Another user of AnimalTracker appeared which motivated me to work on it again. I mainly fixed some bugs. The distribution calculation crashes for example if no range is defined. So after four years there is AnimalTracker 0.72.
