Make Ubuntu play CD and DVD

As Windows 10 is unusable for me I decided to switch to Linux almost entirely. Therefore I’m testing various distributions and make different test subjects use them. I always thought that the biggest challenge would be a dumb user of an old auntie sort. Apparently not! Ubuntu works great for the gunea pig – fabulous. It works even better than new crippled Windows – my dear ginuea pig had Windows XP so far and on her old computer with just 3GB RAM and Core2Duo we had even no need for Lubuntu. And the user interface of full Ubuntu was a love at first sight for the lady. Congratulations to the Ubuntu team.

First challenge was with playing CD – the lady has a big collection of music CDs and the modern iPods and other devil inventions like buying music files on-line are absent from her soul. Unfortunately when she inserts a CD various applications dump core on her. In this case being on friendly terms with a sorcerer who controls devil forces helps.

I was well prepared to take-up the challenge – I had guest Ubuntu in VirtualBox already installed. I even had a USB CD/DVD drive and it took me a second to add it as a CD drive in my virtual machine.

Ubuntu storage settings - CD host drive

Ubuntu storage settings – CD host drive

But when I inserted a music CD the first obstacle appeared – I can see the files, but I cannot play the music – both Rhythmbox and Sound Juicer swear at me with error messages.

Is this a problem for a real hero? I bet not.

Quick Internet search revealed a “passthrough” option:

Ubuntu storage settings - passthrough option for a CD host drive

Ubuntu storage settings – passthrough option for a CD host drive

Astonished that an USB drive is added as a secondary IDE device? No wonder – all the fuss about about virtualization is that all different sorts of strange modern devices can potentially be presented in a well known and stable way to the guest systems. That’s actually a subject per se for the whole article.

Voilà – now Rhythmbox works like a charm. I can listen to the CDs and even make flacs out of it (Sound Juicer required). And what a nice surprise – it connects to the musicbrainz.org and downloads the CD description, song titles etc. Well, to say the truth, not much downloading but rather uploading – apparently Music Brainz collection of classic CDs is rather scarce. However if you google well there is an alternative solution with CDDB of freedb.org which is much richer, they say.

Now the second topic of my post – playing DVD. To make long things short – do not fight with Totem – just install VLC media player that’s available via Ubuntu Software Center. VLC Player has everything you need and worked for me from the first try.

Which Subversion client on Ubuntu?

Well, as you may have noticed I slowly started to play with Ubuntu. As an old Slackware user that started on 1,44 floppies with kernel 0.16 I am really amazed with ease of use and ergonomy of this distribution.

Now I need to find the complete suite of apps that match the needs of a lame business user.

LibreOffice works great, now’s the time for GUI SVN client. Found only three:

Rapid SVN unfortunately seems dormant (http://rapidsvn.tigris.org/).

Than comes a number of options to use full-blown RCS as a Subversion client – that’s not the best option for a non-technical user.

Which one would you suggest? Any other alternatives?
