Thunderbird - Use Gmail as address book

To be reviewed

The article refers to an LDAP server which is installed locally and which connects to Google address book to retrieve the address book information. The guide foresees in the installation on different platforms including Mac OS X.
This can be for that reason a very good alternative to Apple's MobileMe which costs about 79euro per year

Thunderbird - Backup

It seems not very important, but once you loose your appreciated mail history you can be far away from running your business. All of you contacts, appointments etc can be captured in a certain way in your mail archives.
It is therefor very important to make on a regular basis a copy of your thunderbird data so that you can restore it if required.

I have not run into any problem with other problems than Windows yet, so the information is restricted to this environment.

Backing up the data

The procedural steps are very simple:

• go to the directory where the profiles are stored
  The directory can be found (in a standard installation) in \users\\AppData\Roaming\Thunderbird
  The directory named users will seem to be named differently on dutch systems. Using the users directory works however.
• Copy the content of this entire directory
• Paste it on a safe location

How to restore your mails and other data?

Running into this problem after a migration from Vista to Windows 7 I found this article which refers  this tool at this site.
The software - which is a Thunderbird add-on - makes it possible to import thunderbird data of any kind back into the existing thunderbird environment.
Tested the software ... and it worked for importing the folders from a backup set of the thunderbird profile.

apache loadbalancer

This Link is a doc file on how to configure apache to act as a load balancer.

Just in case the document would not last for ever, the scripting involved:

Definition on the virtual host level:

        ServerName www.yourcompany.com
 ServerAlias yourcompany.com

        DocumentRoot /Library/WebServer/Documents

        ProxyRequests Off

        
          Order deny,allow
          Allow from all
        

        ProxyPass /balancer-manager !
        ProxyPass / balancer://mycluster/ stickysession=JSESSIONID nofailover=On
        ProxyPassReverse / ajp://public1.yourcompany.com:8009
        ProxyPassReverse / ajp://public2.yourcompany.com:8009
        
          BalancerMember ajp://public1.yourcompany.com:8009 route=public1
          BalancerMember ajp://public2.yourcompany.com:8009 route=public2
          ProxySet lbmethod=byrequests
        

        
          SetHandler balancer-manager
        

        
    AllowOverride AuthConfig
 

Protection of the balance-manager path.

mkdir /Library/WebServer/Documents/balancer-manager
htpasswd -c /etc/apache2/conf/security/users administrator
cd /Library/WebServer/Documents/balancer-manager
touch .htaccess
vi .htaccess

Text to enter in the .htaccess file:

AuthName "secured"
AuthType Basic
AuthUserFile users

require valid-user

on the balanced server side:

Check the AJP port on the server:
jboss JBOSS_HOME/server/default/deploy/jbossweb-tomcat55.sar/server.xml
tomcat: TOMCAT_HOME/conf/server.xml 
Configuration of this file:

connection link

Not yet tested myself but will not take long ...

Create a VM from a running Windows Environment

Check out the utility disk2vhd which is described here.
It creates a standard Virtual Machine Harddisk from a running Windows system so that the same pc can be run by different VM software distributions.

Browsers - Default proxy configuration

This is just to recall me ... ;-)

WPAD : Web Proxy Auto Discovery

To set automatic proxy configuration use the following line as an automatic proxy script reference:

http://wpad/wpad.dat

This assumes wpad can be found on the local network.
Else no proxy configuration is used.

Move to OpenOffice from MS-OfficeInproductivity Suite

Ever wondered if macro's in OpenOffice are the same as they are in MS-Office?
Well ... they are definitively not.

While discussing the Famous takeover of Sun by Oracle, we got this magnificent product OpenOffice on top of it. So, having all these macro's in our inproductivity Suite we are a little bit stuck with MicroS.


A dear colleague - Marc - has already found some answer and solution to the question : http://www.business-spreadsheets.com/vba2oo.asp.

I have not tested it yet, but knowing Marc I believe him on his words - even those not honorable - that this is the way to go.

Thanks Marc!!
