We can know the version of Debian / Ubuntu we have installed by running the following command:
$ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=14.04 DISTRIB_CODENAME=trusty DISTRIB_DESCRIPTION="Ubuntu 14.04.4 LTS"
If you have installed Debian XFCE and you try putting your computer into hibernation or suspension mode as shown in the figure:
If we want to have a dictionary on our computer we install the following packages:

yum install dictd dict
To handle NTFS partitions in GNU/Linux you should install the package ntfs-3g
Note: From April 2011 the ntfs-3g and ntfsprogs projects joined forces so now everything is in a single suite: ntfs-3g.
Most likely your distribution may already have installed the suite ntfs-3g else you can do it by exec
$ sudo apt-get install ntfs-3g
# yum install ntfs-3g
We can get CPU information in GNU/Linux by typing the following command:
$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 22 model name : Intel(R) Celeron(R) CPU 430 @ 1.80GHz stepping : 1 cpu MHz : 1800.045 ...
If you want to concatenate RewriteCond with logical AND it is enough to put them one under the other view:

If your site respond to urls that contain uppercase and lowercase characters (the same page responds to urls: yourdomain.com/my-Url, yourdomain.com/my-url), taking into account SEO parameters that is not good since the search engines are case-sensitive so you'd have more than one page indexed with the same content.

One of the easiest and safest ways to find duplicate files on GNU / Linux files is using the tool fdupes, fdupes find duplicate files comparing the file sizes, making a check MD5 followed by a byte to byte comparison.

LibreOffice is a free office suite compatible with Microsoft Windows, Mac and GNU/Linux. It has a text processor (Writer), a spreadsheet (Calc), a presentations creator (Impress), a databases manager (Base), a vector graphics editor (Draw) , and an editor of mathematical formulas (Math).
To the previous definition, I would add that it is also compatible with BSD OS (FreeBSD, OpenBSD, NetBSD).
LibreOffice covers a wide range of office needs and therefore can replace proprietary suites such as: Microsoft Office.
