Mendeley with Fedora 16

Few months ago I wrote about my problems with running this very nice software on my Fedora 14.

After while, I've upgrade my Fedora to 15, next to 16 and recently I've noticed that Mendeley again have not worked.
What I've got on console is some memory pointer error:

[teodor@zuzia lib]$ mendeley
Running /home/teodor/download/apps/mendeleydesktop-1.1.3-linux-x86_64/bin/..//lib/mendeleydesktop/libexec/mendeleydesktop.x86_64
loaded the Generic plugin
QSharedPointer: pointer 0x260f550 already has reference counting

Google said that problem is related to the Qt library, again.. this time you can simply run mendeleydesktop with option that switch app to use internal version of library. I've modified running script and set this option on by add after line 199 this statement:

use_system_qt = False

That's all for a while... Mendeley starts but it shows similary error like in previous post.
QSslSocket: cannot call unresolved function d2i_X509
QSslSocket: cannot call unresolved function d2i_X509
QSslSocket: cannot call unresolved function SSLv3_client_method
QSslSocket: cannot call unresolved function SSL_CTX_new

This time solution is rather different. You need to install package openssl-devel:

su -c 'yum install openssl-devel' 

Gnome 3.2 and two screens

GNOME 3.2 try to be considered as the most user-friendly environment around the Linux world. Maybe that's why most settings has to be set up by dconf-editor or via so very intuitive dialog box:

Guess what, I want to set primary display to Goldstar. And I can't do it by some select box, dialog box or other stuff. So the tip:
To set up primary display, you need to drag this black bar on display which you want to be your primary display.
Next point, of course it works, your topbar is moved on your primary desktop, but what was funny  Message bar (bottom bar) was still on laptop display. So next tip:

You need to move your displays on the same level to set up message bar on primary display

Why it cannot look like here, with small checkbox Primary display ? Or maybe it looks to much complicated for typical GNOME user?

Problem with SVN

It looks like that I forget about this blog. Well in some part this is true. I've got a lot to do on my studies and apart of them. But today it' s beautiful day, 30 ºC in Poznan, very nice weather, you know ;) every geeks and nerds love that weather. Back to root topic

Yesterday I was fighting with very strange bug. I create new repository

svnadmin create /home/teodor/svnroot

and next try to commit something to this repo I got some nasty and unclear bug

svn: Commit failed (details follow):
svn: Can't open activity db: APR does not understand this error code

in apache logs there was of course nothing special, like everytime. But previous I got error
that it couldn't save something in db/transaction path. I've change persmisons and that bug was fixed, so also this time this bug was linked with file persmions. svn running under mod_dav module have to be able to store some files under transaction/ directory.

1. First we have to add www-data user to the same group like svnroot have. In my case it was teodor group (I working under Debian OS, every user has own group, it's very nice construction for admin e.g. www servers), so I added www-data to teodor group
2. Next we have to change owners of all files under svnroot/,

   chown -R teodor:www-data *

   in svnroot/ directory
3. And last add read/write permision to user/group :

   chmod -R 0770 *

   in svnroot/

That's all, after that everything should work correct. Have nice day ;)
