OTA Rootkeeper still works when updating to Android 4.2.1

Note (2013-02-18):

There is a newer blog entry available which says that OTA Rootkeeper did not properly reroot the device after upgrading to Android 4.2.1.

The observations I made when I wrote this post seem to be false.

Original blog posting:

And surprise, surprise OTA Rootkeeper has helped me once again to keep root on my Nexus 7 device.
BTW, Google rolled out Android 4.2.1 today and I already received the OTA update :-)

Remove the page title in Confluence PDF export

Confluence always adds a page title when you export a page to PDF format.
If you want to get rid off the title do the following:

Go to

 Browse -> Space Admin -> Look and Feel -> PDF Stylesheet -> PDF Export Stylesheet -> Edit  

and add the following line:

 .pagetitle h1 { display: none; }  

Now PDF exports don't show the title anymore.

Pagebreaks in Confluence PDF Export

It is often necessary to export a wiki page to PDF so managers, customers or other people who can't (or don't want to) access the wiki can read documents.
One thing that embarrasses me the most is that you don't have control over page breaks in Confluence PDF exports. There is - at least to my knowledge - no predefined macro available.
But there is a community macro which solves the problem. Take a look at the pagebreak user macro and try it.
With this macro you are in full control over page breaks in PDF exports.

Making Screenshots with Greenshot under Windows

I don't think I have high requirements for a good screenshot tool but Greenshot is by far the best one I have ever used.
It even has plugins for Jira and Confluence. Moreover it is free to use even in commercial environment. Cool :-)

Keeping root on Nexus 7 when updating Android from 4.1.2 to 4.2

Yesterday Google rolled out Android 4.2 for the Nexus 7 devices. I hesitated to do an instant update because I was not sure if OTA Rootkeeper was capable of rooting my device (using Android 4.1.2) again after the update.
Searching through the usually suspects boards (xda-developers, android-hilfe, etc ...) didn't yield a result. Seems that no one has tried it so far or no one has found the time to post his experiences :(
At least I found out that the Nexus 7 Root Toolkit was updated and therefore able to root a Nexus 7 device with Android 4.2 (afaik your device will be wiped after rooting - please check board posting on xda-developers).
That was the starting signal for me to do the update and try rooting again with rootkeeper. If rootkeeper does not work I still can reroot my device again using the toolkit.
Well it turns out my fear was baseless.
Rootkeeper was able to root my device again so I still have a rooted Nexus 7 using Android 4.2.
Great tool :-)

Multiple Virtual Desktops in Windows 7

Most Linux desktops / window managers support it out of the box: Multiple virtual desktops. I really miss this feature on Windows 7.

A great tool for managing virtual desktops under Windows is Dexpot.

It's a great alternative to VirtuaWin and free of charge for private use.
