Business Relationships  - 
That's one of my favorite articles about business relationships that can go very wrong especially with inexperienced start-up owners and of course small business that things get too cozy...
Definitely worth a share.

Google and Stavros Niarchos Foundation are shaping up the future of the local library starting from Greece.

"The Stavros Niarchos Foundation is investing EUR560 million to build a Cultural Center which will host the National Library of Greece and the Greek National Opera. As part of the project, the Foundation is also funding “Future Library”, an effort that aims to transform public libraries into media labs and hubs of creativity, innovation and learning, attracting many groups who now spend little time there - entrepreneurs, students, unemployed, and immigrants."

"Google is participating, providing design know-how to the architects hired by Future Library to help create innovative and creative spaces."

"Some might have imagined that the Internet would make libraries superfluous or irrelevant. But the reality looks like quite the opposite - the Internet can help libraries become a center for new digital learning and a point of reference for local communities."

Awesome news +Giannis Kollias  thanks.

Recovering from btrfs  error Couldn't read chunk root.

I accidentally dd'ed the wrong disc /dev/sdb when it should be /dev/sdc but i stopped in something like 2 sec. and a small part of my 2tb disc was overwritten with openSUSE  milestone 3 the ruby baked yast flavor :).

I was able to see, access and use my data in the /dev/sdb disc, but not after the reboot, so at the moment unsuccessfully am trying to mount with different options like:

mount -t btrfs -o compress=lzo /dev/sdb /mnt/Kyrios
mount: wrong fs type, bad option, bad superblock on /dev/sdb,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so

mount /dev/sdb /mnt/Kyrios
mount: wrong fs type, bad option, bad superblock on /dev/sdb,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so
mount -t /dev/sdb /mnt/Kyrios
mount: can't find /mnt/Kyrios in /etc/fstab

mount -t btrfs -o compress=lzo /dev/sdb /mnt/Kyrios
mount: wrong fs type, bad option, bad superblock on /dev/sdb,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so

mnt-Kyrios.mount mount process exited status=32
failed to mount /mnt/Kyrios defined by systemd
dependency failed for local file systems unit has failed unit mnt-Kyrios.mount entered failed state.

Useful info:
I am using btrfs-progs 0.20 rc1 and kernel 3.9.2
The whole (1.8TB) disc is pure btrfs with no gpt or other formats like ext4 is just created by mkfs.btrfs /dev/sdb and all my files are in subvolumes Root, Media, Home, Opt, etc.

What i did till now was to use wipefs and delete the opensuse and the dos filesystems that were created by the dd command on top of the pure btrfs disc. Before i use the wipefs i wasnt able to see sdb btrfs info at all with blkid command but now i can as can confirm the blkid output above. At the moment i play with etc/fstab but adding the line:
UUID=b5d84724-f93a-4478-a3eb-3c45c7e5ac72    /mnt/Kyrios    btrfs    defaults,compress=lzo    0    1

/dev/sdb /mnt               btrfs   defaults,compress=lzo 0       1

leaves my system unbootable and asks me to see the journalctl

Not sure what i do next. Can anyone spot the error? How can i fix it?

Big headache with lots of valuable data (no i did not use snapper for backup as was a new disc migration and left it for a month in the back of my mind:()

Any help will be appreciated.
