The printing quality got worse a couple of months ago – low-colour stripes, where I expected bright colour.
I called support yesterday.
He told me to take everything out (all 4 cartridges, the waster toner (box) (in Geman: Resttonerbehälter), and the other beast (I will tell you its name, once I remember)).
I should shake the cartridges a little.
I should clean "it" (that glass area, where the pictures are captured) with something fluff-free and a little wet.
I should let it dry for a couple of hours.
I should also open and close the cover a couple of times, as that would activate a cleaning mechanism.
I actually went for the dry variant, and I was rather successful. I am rather satisfied now.

Google Contacts as XML – rough edges
Some vCards come with a field called SORT-STRING.
It appears to me (I will update this, once I know better), that Google (Mail) Contacts loads this field into their field by the name of "Name (phonetic)". In XML this goes into an attribute of fullName, that they call yomi.

reverse-engineering ORM class interfaces from RDBMS schemas
I found software to create such interfaces for Perl / in Perl; some such software is oriented towards DBIx::Class, some is oriented towards other approaches. I found that in the books on Catalyst.
Is there any such thing for Ruby? Can ActiveRecord do it?
I find that a rather smart thing. Usually you find a lot of existing schemas (if you are in such a situation), and if you are lucky, you can choose the ORM approach.

That documentation includes a nice diagram, and that diagram led me to MySQL Workbench, now I have an idea of how to create nice database diagrams.

RubyForge: XML::Simple (with my experiences as updates)
RubyForge: XmlSimple: Project Info
Rather short after discovering this module, I made use of it with my FRITZ!Box call monitor in order to read my Google Contacts as XML. With this approach, that was a rather easy piece of cake.
Update 2011-03-29:
If an element has not attributes, the (text) content of that element simply gets appended as string to the list at the hash field by the name of that element.
Now if the element has attributes, the (text) content goes together with the attributes to a hash list, that gets appended to that list instead. The (text) content actually goes into a hash field by the name of "content".

Example:
My Ruby code operates like this:text -> "e"=>[ "text"]text -> "e"=>[{"content"=>"text","a"=>"v"}]
x.instance_of?(Hash) ? x['content'] : x

GMarks (Add-ons for Firefox) – Google Bookmarks in the sidebar
GMarks :: Add-ons for Firefox
I loved this explore-like display of my Google Bookmarks in the Firebox sidebar. It's not supported any longer for Firefox 4. And Chrome and Chrome don't have a sidebar anyway.
I really loved adding bookmarks that way.

Google Health can export your health profile as CCR, an XML dialect.
Today I added another "problem" to my Google Health profile.

I started using eRuby to create JasperReport JRXML files
All of a sudden I knew, I would immediately need a template mechanism. During the last "Stuttgart.pm" meet-up Mason got mentioned, but I was already a little familiar with eRuby, so I gave it a try, and it was just the right thing to do. The XML file to handle got smaller and smaller and smaller – really, really nice to see.
Update 2011-03-25:
A few days later I am really rather satisfied with this decision.
Of course: eRuby XML files are no longer clean XML, so they are not supported by any editing mode (apart from "text-mode") in emacs, but then that's not too terrible.
Update 2011-04-20:
Of course (again) being able to deal with eRuby XML files as XML files within nxml-mode would be a charm. There are 2 obstacles to overcome:
In order to interpolate ruby expressions into XML this syntax is used:
but nxml-mode does not accept that for a legal XML attribute value.

Lines starting with '%' are for ruby code, nxml-mode should / may consider them as comments:

an extra blank page on PDF-s created by JasperReport has gone
The JRXML, I am creating programmatically, caused the generated PDF to have an extra blank page.
I didn't care a lot, as long as I had not achieved my main goal. Now, that I am going to deliver (OMG!), I tried to smooth that rough edge. As I had not clue, where the problem source really was, I urgently needed to solve that problem today. Spent some time on it, solved it!
My document has only two bands: the Title and the the Background Band.
The Title Band actually doesn't share the page space with any other band. Therefore I thought it may take all the 842 points of height, that the document has itself. That's apparently not true. Apparently the Title Band must be at least be one point smaller the available height. If I respect that rule, I don't have that extra blank page any more.
