Ubuntu 12.10 has released with lots of new exciting features, but most users didn’t welcome the one feature which – integrates the amazon products in Unity dash serch results.
So, if you’ve installed Ubuntu 12.10 (Quantal Quetzal) and hates this amazon results in Dash search, then you should know that it can be easily disabled from System Settings -> Privacy -> Include Online results in search -> OFF.
Ubuntu 12.10 (code name: ‘Quantal Quetzal’) stable is out! the ISO (~800MB, for USB/DVD) is available for download. It’s the second major release this year, preceded by Ubuntu 12.04 LTS (Precise Pangolin).
If you want to know about the major changes or features coming in this version, then read – what’s new in Ubuntu 12.10 . In short, graphics performance would be better, you can easily integrate web apps to desktop, improved security (you can enable the entire disk encryption during installation step itself), unity has improved a lot and new packages/apps as usual (Python 3, GIMP, Firefox etc).
Unity is the default desktop environment, but if you’re not happy with it, then you can try some alternative desktop environments. For absolute beginners, I recommend this article – 10 things to do after installing Ubuntu 12.10, specially if you are facing problem in getting things done on Ubuntu 12.10 or just moved in from Windows 7 or XP.
Unity is the default desktop environment in Ubuntu 12.10. Although, it has improved a lot but if you’re still looking for an alternative desktop with classic GNOME 2 style layout then you may try MATE.
MATE is a GNOME 2 based desktop, it’s easy to use, and the it’s stable too. it’s the default desktop environment in Linux Mint, an Ubuntu based distribution, more human-friendly for beginner users.
MATE Desktop environment is available for various platform, including ubuntu, fedora, etc. In Ubuntu, the best way to install MATE would be through the official PPA.
PPA(Personal Package Archive) is great for installing new and cool apps/utils in Ubuntu or similar GNU/Linux distro such as Linux Mint etc. Due to PPA, publishing and distributing apps has become very easy.
Sometimes you may want to remove an application installed using PPA (may be because some sort of conflict occurred between the app installed from official repository and PPA) or may be you added a wrong PPA address and you get some error messages (on terminal, e.g file not found) or update manager is not working properly due to broken PPA etc. In that case, just follow any of the method (to uninstall the ppa) –
Removing a PPA address in Ubuntu 12.04/12.10/.. Linux Mint / similar_distro
Method #1. remove the ppa file(*.list) from /etc/apt/sources.list.d directory. Open a terminal and execute the command
ppa_1.list ppa_2.list .... ppa_no_longer_required.list
sudo rm /etc/apt/sources.list.d/ppa_no_longer_required.list
Method #2. If the ppa contains a newer version of standard package, then you have to use the command –
sudo ppa-purge <ppa_address>
ppa_address will be in the format of ppa:name/sub_directory (if required)
(so that it fall back to old version of the application as if there was no PPA)
Method #3. From Software Sources – go to Ubuntu Software Center -> software sources -> other software (In Ubuntu 12.10, you can directly go to software sources) and uncheck the ppa you want to remove.
Finally, update the package cache, using the command –
Markdown is a lightweight markup language. Using markdown, you can write content in a simple and easy to read plain text, and finally, it will generate the equivalent html(valid XHTML or html) for publishing on web. So, it’s certainly more human friendly for web writers, specifically if you are looking for a simple and efficient replacement for WYSIWYG editor.
Ubuntu 12.04/12.10 comes with a plain text editor called – gedit. gedit is good text editor, you can also use it as a markdown editor (it will highlight the syntax well) but the problem is that – you can not preview your document. You can’t export your markdown text to html or pdf or any format. You will have to manually export it using the command line utility and if anything goes wrong, then again – edit -> save -> export. That’s not very efficient.
So a dedicated a Markdown editor is obviously, a better choice. There are many markdown editors available for Ubuntu 12.04/12.10 such as ReText, Uberwriter etc but ReText is the best one!
