This has changed to just System -> Startup Applications, in Precise 12.04 at least.

comment Is there a VRML2 (VRML97 / WRL) viewer?
As of Ubuntu Trusty 14.04, view3dscene is also packaged, as discussed at this (duplicate) question: (VRML) Files, How to Render - Ask Ubuntu. It has a much more intuitive interface than whitedune for simple viewing.

comment (VRML) Files, How to Render
view3dscene is packaged in the standard ubuntu archive for safe, convenient installation via your choice of package management tools as of Trusty 14.04 LTS. As noted in Is there a VRML2 (VRML97 / WRL) viewer? - Ask Ubuntu‌​, whitedune is an option in earlier versions of Ubuntu, back to lucid 11.10, but the interface in view3dscene is much more intuitive.

Odd. The /etc/default/keyboard approach works fine for me on Ubuntu trusty.

comment Are there any fax sending applications?
Do you have a fax modem and a phone line? E.g. a Class 1, Class 2, or class 2.0 fax modem? Or are you looking for something that would use VOIP (FOIP)? Or perhaps a web service like metrofax?

comment How to install Django 1.6?
sudo pip install is a bad practice, which may work for django but can really screw up someone's system in other situations. Don't undermine the advantages of having Ubuntu manage your packages. The clean way to do it is with virtualenvwrapper.

comment Find duplicate files and folders and move these to a different folder
I agree with @AndersonGreen that the question of finding duplicate folders / directories needs an answer. See one option at Find all folders in a directory with the same content - Unix & Linux Stack Exchange

comment How to use Rhythmbox python console
Note that at least as of Ubuntu Trusty tahr 14.04, rhythmbox embeds python 3.4.0. So the command 'print "hello world"' is a syntax error ;) Instead, use the new Python 3 print function: 'print("hello world")'

comment Installing Java 7 Update 25 on 12.04 LTS?
PPAs can indeed be dangerous. But they can also be smart and more secure than a direct download, in the sense that they automate the process of upgrading. If the people running the ppa are trustworthy, and they sign their packages etc, then they are a good alternative to having people check the checksums of the tar.gz themselves, do the intstalls, and then constantly watch for notice of the need for a security update, and do it all over again. Note also that the ppa package does a number of other "update-alternatives" calls, for various installed programs that use java.

comment Can I control brightness on second monitor?
This is not in the normal repos, but is in the software center at least for 12.04. It does not change the backlight brighness, but does change the overall brightness, though I'm not sure how. It says it uses a proprietary license, but also says it is "gpl-3". Very odd. And I'd like a command-line interface that I can script to gradually lower brightness in the evening. But I'm still glad to have it - thanks!

comment What are the differences between 32-bit and 64-bit, and which should I choose?
@Sergey But I'm pointing out that even with 8 GB, I typically have some swap due to tons of browser tabs. And in both cases in your charts with Firefox, there is swapping (in 1 GB), so I can't learn much there. If I could get, say, 50 of my typical browser tabs without swapping using 32-bit, while I'd start to swap at 40 browser tabs with 64-bit (I'm making the numbers up of course), then 32-bit starts looking nice. But I don't know if the 30% vs 10% rule applies to javascript/web pages/threads in modern browsers.

comment What are the differences between 32-bit and 64-bit, and which should I choose?
I'm curious how modern browsers with lots of open tabs and javascript fare here. I often run into swap (even with 8 GB RAM) by opening up lots of tabs, and modern web sites use lots of javascript libraries etc. How do the memory and cpu speed compare for heavy chrome or firefox usage?

comment Ubuntu cgroup architecture: cgroup-lite vs cgroup-bin and default config for lxc, libvirt-bin?
I've seen some bugs that may be related, such as lxc-start: failed to spawn

comment lxc-start: failed to spawn
@NeilenMarais lxc doesn't depend on cgroup-lite, but recommends it (or cgroup-bin). That could be the problem.

comment Is it recommended to create a cgroup per process?
It would help to describe what kind of monitoring data you want to get, and alternative options you've considered, and why you'd avoid both systemd and upstart, and how you start your daemons in that case.
