What to do after install Fedora?

1. Install a decent Terminal (ROXTerm) and personalize it
Go to the software centre and search in the section "System-->Terminal emulators" and install a terminal emulator. I tried ROXTerm, and I can say it works very well and it is very customizable, so you have to try it.
I prefer to use a black backgroung with the font in green (like old computers).

You also can use Gnome Tweak Tool to personalize more and more your Fedora.

PRELIMINAR NOTE:
If you are coding in Terminal/command line the system show a message that says "you need to be root user to execute that command" or something like that, you have to write:

su

and then write your password, and then write or copy/paste the commands

2. Install a Musique music player and video codecs
To install the codecs you must go to the software centre in the section "Complementos" and install it all. Especially "extra codecs", that contains the codecs to play mp3, mp4,... files.

You can download 'Musique' and 'Audacious' from the software centre.

Codecs
Before we get started, the RPM Fusion will need to be enabled on you system (if it isn’t already). Open a terminal window and enter the command below and the RPM  Fusion repository will be installed and enabled.

sudo -c 'yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm'

Proprietary media codecs do not come bundled with Fedora because it does not mesh with Fedora’s ‘Free And Open Source’ philosophy (and for legal reasons). However, if you have files (like .mp3 files) that you want to play on Fedora, you’ll need to have these codecs installed. Enter the command below into your terminal window, and soon after the installation finishes, all of the proprietary media codecs that you’ll need will be installed. Then:

sudo yum install gstreamer gstreamer-ffmpeg gstreamer-plugins-bad gstreamer-plugins-bad-free gstreamer-plugins-bad-nonfree gstreamer-plugins-base gstreamer-plugins-good gstreamer-plugins-ugly gstreamer-plugin-crystalhd gstreamer1-plugins-bad-freeworld gstreamer1-plugins-bad-free gstreamer1-plugins-good gstreamer1-libav ffmpeg


Also

# yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm

# yum install gstreamer gstreamer-ffmpeg gstreamer-plugins-bad gstreamer-plugins-bad-free gstreamer-plugins-bad-free-extras gstreamer-plugins bad-nonfree gstreamer-plugins-base gstreamer-plugins-good gstreamer-plugins-ugly install faad2 faac libdca wget compat-libstdc++-33 compat-libstdc++-296  xine-lib-extras-freeworld

And Fedy

su -c "curl https://satya164.github.io/fedy/fedy-installer -o fedy-installer && chmod +x fedy-installer && ./fedy-installer"

With Fedy you can install easily the media codecs and also a lot of system improvements!

If doesn't work

yum install gstreamer-plugins-bad gstreamer-plugins-bad-free-extras gstreamer-plugins-bad-nonfree gstreamer-plugins-ugly gstreamer-ffmpeg gstreamer1-libav gstreamer1-plugins-bad-free-extras gstreamer1-plugins-bad-freeworld gstreamer1-plugins-base-tools updates gstreamer1-plugins-good-extras gstreamer1-plugins-ugly gstreamer1-plugins-bad-free gstreamer1-plugins-good gstreamer1-plugins-base gstreamer1

sudo yum -y install x264

And in last case

su -c'yum update'

Then again install the codecs

Flash Player
yum install http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm -y

sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux

sudo yum install flash-plugin -y

Or download the .rpm from the official website

3. Install PlayOnLinux and Wine

sudo yum localinstall http://rpm.playonlinux.com/playonlinux-yum-4-1.noarch.rpm

sudo yum install playonlinux

For Wine:
http://sourceforge.net/projects/wine/files/Source/wine-1.6.2.tar.bz2/download?use_mirror=ufpr

4. Install basic utility tools

Paint for Linux: Kolourpaint

Download the .rpm from rpmfind.net/linux/rpm2html/search.php?query=kolourpaint

In my case Fedora 20 32 bits x86 ftp://rpmfind.net/linux/fedora/linux/releases/20/Everything/i386/os/Packages/k/kolourpaint-4.11.3-1.fc20.i686.rpm

Text editor: Sublime

wget -c http://c758482.r82.cf2.rackcdn.com/Sublime%20Text%202.0.2.tar.bz2
tar vxjf Sublime\ Text\ 2.0.2.tar.bz2

sudo mv Sublime\ Text\ 2 /opt/

sudo ln -s /opt/Sublime\ Text\ 2/sublime_text /usr/bin/sublime

To run it from the terminal/command line, just type “sublime” and we are good to go

Compression (like Winrar)
su -c 'yum install unrar unace unzip file-roller xarchiver'

CCleaner for Linux: Beachbit
You can search it in the Fedora software centre.

Video converter: Handbrake
Very powerful, fast and complete. Is a rare video converter but is the best I know and it can be installed via Terminal:

wget http://negativo17.org/repos/fedora-handbrake.repo -O \
   /etc/yum.repos.d/fedora-handbrake.repo

yum install HandBrake-gui

If it doesn't work, you can download from http://sourceforge.net/projects/handbrakerpm/files/latest/download

Download manager: Jdownlader
wget http://installer.jdownloader.org/jd_unix_0_9.sh -O jd.sh

chmod -x jd.sh

./jd.sh

Bittorrent client: Flush
You can find it in the Fedora software centre.

Media player: VLC

yum install vlc

RecordMyDesktop
It works like Fraps, a program that can 'film' what you do on your computer. An alternative is Kazam


5. Allow sudo in Fedora (requires root)
su -

# echo 'username  ALL=(ALL)     ALL' >> /etc/sudoers

# exit

Note: replace username by your username. Verify if is all ok.

$ sudo yum update

6. Install better icons
Fedora can be a very good SO, but have ugly icons, so you should install better icons as 'Pacifica icons' used in the Elementary distro.

http://fsvh.github.io/

Download from this page the zip, extract and place the folder Pacifica on home/user/.icons or usr/share/icons. With GNOME tweak you can activate it.

7. Other things that you'll may use
I installed Fedora 20 Electronics Lab, so it comes by default with a lot of interesting tools like Octave (similar to Matlab), KiCAD, etc; but also you'll may use:
-Comix comic reader
-Photoshop
-Evernote for Linux: Everpad
-ROS (for robotics)
-Fritzring (for circuits)

Partition manager: blivet-gui

The most complete partition manager for Fedora blivet-gui

If you'd like to test blivet-gui, there is a copr repository for Fedora 20.
Then, you can add it and install blivet-gui using:

su -c "dnf copr enable vtrefny/blivet-gui && dnf install blivet-gui"
