lookbehind regex in PHP

Today, I was facing a problem how to split something like following text

a="Some Text" b="Some more Text" c="Even more text about \" this text\"" d="aaaaaaa"

into array, into pairs key => value. I couldn't just use explode(), because spaces could be inside the quotes..

After a little searching, I founded that solution lies in lookbehind regular expressions.. Nifty things ^_^

This

/(?<![\\\|=])\" /

expressions would split it into following array:

array (

  0 => 'a="Some Text',

  1 => 'b="Some more Text',

  2 => 'c="Even more text about \" this text\"',

  3 => 'd="aaaaaaa"',

)

so exactly what we wanted :)

YaCy on Archlinux

Today I decided to deploy YaCy on my VPS running Archlinux. I installed package and all went well until I noticed, that no images are being displayed. After some searching (30 minutes?) I finally figured it out.

To correctly show (generated) images, YaCy requires X Server and libcups, even on server running only in console.

I already requested adding those two packages into dependecies, but until it's done, if you having problem running YaCy without X server, just run "pacman -S xorg-server libcups" and it should be ok.
