Emacs 24.4 in Ubuntu 14.04

How to Install Emacs 24.4 in Ubuntu:

At the moment of writing this tutorial, there’s no PPA repository that contains Emacs 24.4. Fortunately, it’s not hard to build it from the source tarball. I’ve done it successfully in 64-bit Ubuntu 14.04 LTS. Below steps will show you how:

1. If have the old Emacs 24.3 installed, you may first remove it from Ubuntu Software Center so that you can install the new version over it.

2. Press Ctrl+Alt+T on keyboard to open terminal, or open it from the Unity Dash.

Open Terminal to run commands

3. Run command below to install the build-essential:

sudo apt-get install build-essential

4. Install the required dependencies:

sudo apt-get build-dep emacs

While the installing process, you’ll be asked to configure the Postfix.

5. Now download Emacs 24.4 from its official FTP download page.

Emacs FTP download Page

6. Extract the source and go into the result folder in terminal:

cd ~/Downloads && tar -xf emacs-24.4.tar.* && cd emacs-24.4

7. Finally compile the package by running commands below one by one.

./configure

make

sudo make install

Once done, you should be able to launch Emacs by running emacs or emacs-24.4 in terminal and lock the shortcut to the Unity Launcher.

To create a launcher for Emacs 24.4. Thanks to Emad Khoury, run command to create a .desktop file and edit it with Gedit text editor:

sudo gedit /usr/share/applications/Emacs-24.desktop

When the file opens, paste below into it and save the file.

[Desktop Entry]
Version=1.0
Name=Emacs-24
Exec=env UBUNTU_MENUPROXY=0 /usr/local/bin/emacs
Terminal=false
Icon=emacs
Type=Application
Categories=IDE
X-Ayatana-Desktop-Shortcuts=NewWindow
[NewWindow Shortcut Group]
Name=New Window
TargetEnvironment=Unity

Depends on where you install Emacs 24, you may replace the value of Exec and Icon to the path to executable and shortcut icon file.

minecraft ubuntu 14.10

Installing Minecraft in Ubuntu is quite easy. All we need to do is install Java, download and run the .jar executable from its official website.

1.) To get better game experience, you may first install graphics driver for your video card:

  • For Intel graphics, you’re good to go with the default open-source driver.
  • For NVIDIA or AMD graphics, it’s better to use a proprietary video driver. Open Additional Drivers utility from the Unity Dash, select the NVIDIA or AMD driver from the list and install it.

2.) For Java, you can either install OpenJDK Java 7 from Ubuntu Software Center or install Oracle Java from PPA.

To install OpenJDK Java 7, click the button below to bring up Ubuntu Software Center and click the install button.

Click to Install OpenJDK 7

To install Oracle Java, see this post or just run commands below one by one in terminal:

sudo apt-add-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java8-installer

3.) Once Java Runtime is installed, download the Minecraft.jar file from:

Minecraft Download Page

4.) Make the Minecraft.jar file executable.

To do so, right-click on the file in Nautilus browser and go to its Properties windows -> Permissions tab and finally check the box where it says “Allow executing file as program”.

Make Minecraft.jar executable

5.) Finally start the Minecraft Launcher:

MineCraft Launcher

When the launcher opens, log-in with your account and click the Play button. After downloading required packages, you’re finally able to play the game:
