KDE

The ‘focus‘ word has many meanings, ranging from the optical concept of ‘good convergence of light rays generated by an object’ to the cognitive process of directing the attention to a particular target while ignoring other targets.

Now the interesting part: this concept can be used in computers too, especially in user interfaces, to direct the user to relevant information or to help him through a step-by-step process. How to do that? Since every image you see on screen is ‘on focus’ by default, you can easily unfocus unuseful information.

Blurring is the act of altering images so they appear out of focus. My Maestro[2] and other illustriuos people already talked extensively about this topic here on planet KDE. However you don’t improve the world until a technology becomes available to everybody, right?

Then some days ago I read on notmart’s blog that plasma and kwin supported blurring the background on windows.. so I rebuilt KDE4 svn, restarted it, and… boy.. does it make a difference!

Kernel 3.18 development – the kernel column

Linus Torvalds announced Linux 3.17, the Shuffling Zombie Juror, saying, “The past week was fairly calm, and so I have no qualms about releasing 3.17 on the normal schedule”. The latest kernel includes a number of nice headline features, such as the new getrandom() system call and sealed files APIs that we covered in previous issues of LU&D. Linux 3.17 also includes support for less highlighted new features, such as new signature checking of kexec()’d kernel images and sparse files on Samba file systems (which is significant for those mounting Windows and Mac shares).

Python 3 Support Added To The GNOME Shell

The GNOME Shell 3.15.2 release fixes some visual glitching, improves the layout of the extension installation dialog, supports the CSS margin property, and offers other bug fixes and minor enhancements. Most notable to GNOME Shell 3.15.2 though is there's finally Python 3 support. Many GNOME components have long ported their Python 2 code to Python 3 while GNOME Shell's Python support has just received the Py3 treatment. Details on GNOME's overall Python 3 porting work can be found via this Wiki page. Read more
