Jupgrade [migrating undefined]

The last week or so I've been working on updating and migrating a Joomla! site. Going from Joomla! 1.5.26 to 2.5 seemed to be smart upgrade. Unfortunately I ran into some problems when trying to use Jupgrade to migrate the database. I also got some problems with some outdated components but I got most of the stuff working.
The biggest problem I encountered was the "migrating undefined" problem. Luckily I found an easy, but perhaps ugly, solution to this problem.

Converting imagefiles

Using your digital camera or mobile phone makes it easy to take snapshots you want to share online, on facebook or by email. But the size of these images can be quite big since many cameras and mobile phones take pictures at 8-12 Megapixels. Then it is nice to know about the convert-command on linux that will allow you to batch convert images.

Changing the info for a pdf-file

Usually when creating a pdf-file I do it from Libreoffice. But sometimes I need to scan some pages and create a pdf-file from that. On those occasions the title showing up in the pdf-viewers title bar is either blank or is being filled by the scanner software.
I like my pdfs to look more professional so I change the Title value and usually also the Author value.

Adding an index to your pdf-file

Have you ever created a pdf-file from multiple documents? And wanted to have a clickable index for the pdf-file?
on more than one occasion have I created documents that I need to make an index to, and after some gogling I have come up with the solution that I will share in this article.
We only ned a couple of files and programs to make this work.

Merging pdf-files

Merging and splitting pdf-files is very easy if you have pdftk installed. Using it is as simple as you could ever want it. But I usually end up having to check the man-page if I want to do more complex stuff. I use it everytime I need to do something with a pdf-file. Although there are GUI options my preferred program for working with pdf-files are pdftk.

Google AdSense

Google AdSense is a way of trying to make some extra income for making an effort on the internet... As long as your website is accepted. My blog was disapproved because of not enough content.

Does adding this little piece of content help at all?
I suppose not... I will continue working this blog for a while and then request a new audit.

Mozilla Thunderbird have quite a few good extensions. One of them is MailMerge. This extension allows for using Thunderbird to send personalized emails. Of course there are some rules you need to obey to for this to work. But here is a quick how-to for sending personalized emails to a group of friends or colleagues.

Linux Project Blog

This blog is about using linux to do different things. We will be using both server and desktop versions. Since Linux have so many different flavours I find it easier to stick to one distro for both my server an desktop. Currently this is Ubuntu LTS editions. I prefer LTS editions because I find updating every 6 months to be too often and the differences are small between the versions.
