Formatting Dates in JExcel

Jexcel has an annoying Feature: It exports Dates always as UTC.
They have published some kind of workaround for reading Excelfiles, but it does not work for Writing Excel files.
My workaround:

TimeZone tz = TimeZone.getDefault();
int offset = tz.getOffset(date.getTime());
Calendar cal = new GregorianCalendar();
cal.setTime(date);
cal.add(Calendar.MILLISECOND, offset);
DateTime datetime = new DateTime(j,i, cal.getTime());
WritableCellFormat cf = new WritableCellFormat(df);
datetime.setCellFormat(cf);

Things not working in Ubuntu oneirc

* Upgrading the flashplugin. Solution: deinstall the flashplugin before doing a system upgrade
* Nvidia-Twinview + unity. Solution: Don’t use unity
* Migrating .kde from 4.6 to 4.7: So far none, i made a new user
* Booting is hanging for 2minutes if there is no network connection.
Solution: So far none.
Resume: Don’t upgrade now

Modifying Keyboard layouts on Ubuntu

1. Modify the layouts in /usr/share/X11/xkb/symbols
2. Delete xkm files in /var/lib/xkb/*
3. Call setxkbmap
All the tutorials on the internet don’t mention the xkm files, so it took me some time time to find out, why my changes were not applied.

jboss5 + seam on FreeBSD

  1. Install jboss5 port
  2. ln -sf /var/jboss5 /usr/local/share/jboss5/server
  3. edit /etc/rc.conf: 
    jboss5_enable="YES"
jboss5_jvm_opts="-server -Xms128m -Xmx512m -XX:MaxPermSize=256m \
-Dorg.jboss.resolver.warning=true \
-Dsun.rmi.dgc.client.gcInterval=3600000 \
-Dsun.rmi.dgc.server.gcInterval=3600000 -Djboss.bind.address=0.0.0.0 \
-Djava.awt.headless=true"

    Notice the jboss.bind.address and java.awt.headless=true (to prevent annoying warnings about missing X11).

  4. Edit /etc/sysctl.conf: 
    kern.ps_arg_cache_limit=1024

    Necessary for the shutdown script to work

  5. Add 
    jboss.home=/usr/local/share/jboss5

    to seam’s build.properties

  6. …to be continued

Bustraveling in Turkey

I recently traveled a week in Turkey by bus. Here are my experiences:
Metro: Traveld Kapıkule/Edirne-Istanbul, Kapıkule/Edirne-Bursa. Sales Office Experience: . At the Metro Haskovo Counter they speak understandable Turkish and are also very friendly. At the Edirne Counter (Metro Volkan) personal was very stressed and unfriendly. Avoid travelling to or from Edirne with Metro anyway, the bus stops somewhere on the highway, if it stops (In my case it didn’t which resulted in some adventourus hitchhiking to Haskovo).
Ulusoy: Traveled Bursa-Ankara. Sales Office Bursa was friendly, but the Conductor was not very friendly and threw his garbage out into the nature. Ulusoy uses its own otogar in Ankara, which is not really convenient.
Kamil Koc: Traveled Ankara-Canakkale. Not the fastes but the most luxurious bus with personal TV stations and a big plus for the head phones.
Canakkale Truva/Soma Seyahat: Traveled Canakkale-Edirne: Unprofessional counter personal. Suicidal driver. I am lucky i survived.
