Deluge: ‘PreferencesManager’ object has no attribute ‘do_config_set_func’

Deluge is a torrent client. Some days ago I updated it to latest version (1.3.12) on my ArchLinux and the Scheduler plugin was not working as it should.

I found the following error in the log

AttributeError: 'PreferencesManager' object has no attribute 'do_config_set_func'

In the forum title Scheduler locked in slow mode, the reply stated

Yes sorry I make a mistake in 1.3.12 when fixing another issue. Here is the fix applied for next release: http://git.deluge-torrent.org/deluge/commit/?h=1.3-stable&id=cdf301601fe71bd697f3796cf0a5656d437d140e

Mac screen sharing and Remmina on Linux

I have a Mac mini (Yosemite) and a laptop with Xubuntu 14.04. I needed to remote control my macmini from my laptop (in same network).

First, I setup the mac according to the knowledge base.

Second, I configured Remmina (1.2) for remote access.

Windows 10 vs Gnome 3

The following is the opinion of the writer Avish Kumar

Linux is years ahead of Windows. Their approach is different. In near future windows won’t stand anywhere around Linux and there is nothing for which a Linux user need to go to Windows 10.

Thunderbird and OpenLDAP

I setup OpenLDAP according to the archlinux wiki and this page. 

The server was up, search ok and I was ready to setup thunderbird to use the LDAP. 

I setup thunderbird and then no entry in the view. I thought it was some fault on the configuration. I tried JXplorer, ldapaddrbook, apache directory studio and couldn’t find the problem. 

I stumble upon this page via google and I stop scratching my head and pulling my hair. 

This is a thunderbird-bug – not an OpenLDAP issue:

ldap-address-book gets synchronized but you do not see any entries in the overview

but it is there when you start typing in an address of a ldap-reciepient…so it’s there but you have to start searching by typing in some letters

plz consult the mozilla-people for further infos and bug-cleanup as this is a third-party application developed by them
