May 5, 2010I have sendmail setup with sasl and multiple domains.I'm sure there is an easy fix for this but I can send emails to anyuser@<anyofmyvirtualdomains.dom> and it will be accepted. I'm just trying to cut down on any confusion that may occur later. Is it possible "restrict" or classify a user into a particular domain? I've setup virtusertable and aliases but no luck in accomplishing my goal.I've searched to find no particular information on this.

General :: Recommended Directory Structure For Application System Development?
Apr 27, 2010I have to set up my development environment under OEL 5.4. The internal directory structure is more or less fixed, the question is where to put the whole application tree in standard FHS for the development phase.For production, the system will be deployed on a server where data is kept with an Oracle 11g database. Development goes with JDeveloper which has its own internal application/project directory structure; however, I whould like to be independent from this. Unfortunately, by carefully studying the web for FHS, if I will adhere to it I only find ready-made packages to put under /opt, for example. No development aspects are mentioned. make some proposal, possibly with respect to best practices.

Ubuntu :: Exporting ALL Evolution Address Books?
Mar 26, 2010Exporting the default evolution address book to a cvs file is relatively simple:"There is an obscure utility called evolution-addressbook-export that does the job. To find it use the locate command on your system as it isn't in your normal path. Mine was located :
/usr/libexec/evolution/2.6/evolution-addressbook-export
to use is simple :
/usr/libexec/evolution/2.6/evolution-addressbook-export --format=csv >contacts.csv"[URL]..
But this ONLY exports contacts from the default address book (Personal address book), not other address books one may have created in evolution. SO HOW SHOULD THE COMMAND BE MODIFIED TO EXPORT ADDITIONAL ADDRESS BOOKS THAT ONE HAS CREATED?Cannot find an answer to this anywhere - most frustrating.
Ubuntu :: 11.04 Evolution 2.32.2 - Multiple Address Books
May 18, 2011I'm having an issue in Evolution after upgrading to 11.04 in which upon autocompletion when typing emailaddresses in the To/CC fields, is slower than molasses.
I'm trying to troubleshoot this issue, but in my Evolution the Personal addressbook (from Contacts) is displayed 7 times. That is I have one CouchDB, one entry for the Exchange 2003 server, and 7 "On This Computer/Personal" addressbooks.
Any contact I add in one of these end up in every single of the others, even though none of these addressbooks are in use. But I can give every addressbook an individual name, so it appears to individual addressbooks.
I have searched the home folder and /usr for where I can find these and remove them, but they simply are nowhere to be found.
Does anyone know in which file I need to edit in order to fix this, and does anyone else have the slow autocompletion problem after upgrading to 11.04?
Ubuntu :: Can't Open Evolution Address Books
Jul 2, 2011Suddenly I can't open some of my evolution address books. I get this error message :
Unable to open address book
This address book cannot be opened. This either means that an incorrect URI was entered, or the server is unreachable.
Detailed error message: Invalid source
This doesn't happens with 3 out of 5 address books. All the books in question are on my computer. My ubuntuone and google address books work fine. I've looked around for answers, but most of the issues seem to be related to the ubuntuone book, which is working fine for me.
Software :: Audio Books Storing With Categorization
Apr 8, 2010I'm starting to take advantage of a lot of the software packages that come with Ubuntu, and I am finding an abundance of software for just about everything. So far, the best application for my needs is the Calibre E-Book Reader, and I am wondering if a similar program exists for audio books. Something which would store them altogether, and categorise them by title, date, genre, author etc.

Ubuntu :: Thumbnailing Of Comic Books Fails In Lucid
Apr 19, 2010There is a following convention: tar/zip/rar archive renamed to cbt/cbr/cbz is recognized by some application as a comic book file, so file managers can open it using corresponding viewers, which treat sequence of images inside as pages of a book. And nautilus used to recognize cbt files, making thumbnails from the first image in such renamed archive back in karmic. It still recognizes such file as "Comic Book Archive" after upgrade to lucid but fails to thumbnail it now. It tries to do that though, showing icon with the clock for a moment, but almost instantly fails, printing "Error loading document: File type Tar archive (application/x-tar) is not supported" to the console. When I am trying to open cbt file in evince (which is responsible for making document thumbs in gnome afaik) it displays exactly the same error message. Cbt files itself are completely valid and can be opened easily with Comix for example. Thumbs created in karmic are still displaying fine as well.

Jan 4, 2011I noted in another post that gtkpod was suggested for audio book use. I had a look at the documentation but it did not give any clear indication of this.
Using iTunes it is possible to link all the tracks on 1 CD which makes for uninterupted listening and will also offer the facility to stop and re-start the book from where I left off. Is this available using gtkpod?
My laptop is purely a Linux setup. I am told that I would have to change the BIOS settings which is well beyond my capabilities. As I particularly wish to keep my system pure I need to find the best possible way to work with audio books rather than to capitulate to Microsoft or Apple.
