Ubuntu 12.04 LTS is out : Download Now!!

Ubuntu 12.04 LTS (a.k.a : Precise Pangolin) stable version has released. So if you’re using older version or the beta version of 12.04 then you can install Ubuntu 12.04 LTS or upgrade the existing one.

12.04 is a LTS (Long Term Support) release so if you wanted a stable version of Ubuntu with longer support (that’s natural -> many people are screwed due to the frequent release cycle of Ubuntu) then you should stick to 12.04 LTS unless there is any specific reason to not.

Here’s an screenshot of Ubuntu 12.04 LTS : looks pretty similar but there are lot of new cools features in Unity, specially the new HUD (Head Up Display, want to checkout – hit Alt key).

The new version of Ubuntu has a lot of changes and new features – specially in terms of performance and Unity has also improved a lot. Gnome shell interface has improved but if you want KDE or Xfce or something else, no problem. The default desktop may be unity but you can use whatever you want.

How to Install Eclipse IDE on Ubuntu 12.04

Eclipse IDE (Integrated Development Environment) is the most popular IDE among Java developers although it is also used as an IDE for C++, PHP, Rails (through aptana plugins), Javascript and Android (SDK) development. In fact – it’s the most popular open source IDE, and it is very extensible (through plugins) so whatever language you use – you can get a way with Eclipse.

Anyway – IDE helps a lot in setting up a complex development environment (in Java or others) – so it may help you in increasing your productivity (although I’m not sure about this, I feel more productive on a simple text editor like gedit or very powerful text editors like Vim or Emacs, I don’t use Java either). Although, I’ve written this post primarily for Ubuntu 12.04 LTS (precise pangolin) users but it should work well in other versions of Ubuntu as well as on other similar distributions – specially Debian based distributions e.g Linux Mint, Kubuntu etc.

steadyflow Download Manager

Download Manager for Ubuntu 12.04

If you’re going to use Ubuntu 12.04 LTS as your primary OS then you must install few basic things first (mandatory), then other essential programs as required. Download Manager is really very useful if you download a lot of stuffs directly over the http or ftp protocol (I mean, from browser, rather some other way like torrents). For downloading mp3 tracks from soundcloud, you can also checkout this web based tool : SoundCloud to mp3 downloader.

Although your web browser (Firefox is installed by default) also provide some options to manage downloading but it doesn’t has much features. So you may try some download managers that can easily resume/download stuffs without any hassle.

How To install Java / JRE on Ubuntu 12.04

Ubuntu 12.04 is a LTS (Long Term Support) release, for desktop as well as server edition. Just after a fresh install of Ubuntu 12.04, you need to install few things to get everything running, atleast for common tasks (you may find my previous post useful – things to do after a fresh install of Ubuntu 12.04).

Now, you want to execute Java programs then you must – so you just need to install a JRE (Java Runtime Environment, includes Java Virtual Machine, JIT (Just in Time compiler, IcedTea plugin)) and you’re ready to run Java Applications and Applets (not so popular anymore, JavaScript rocks!).

But, remember if you want to develop Java Applications then you need more (JDK, Docs etc) than just a JRE. So checkout this post – Install JDK on Ubuntu 12.04 if you want full development environment rather then just the run time environment.

Installing JRE/Java on Ubuntu 12.04

There are many implementation of Java Runtime environment but we will stick to the Open Source implementation of Java – OpenJDK (Open Java Development Kit). The latest stable version is openjdk-7 (although v 8 developer preview version is also available). a terminal (hit Ctrl+Alt+t, to open a bash shell or terminal or whatever shell (such as zsh) you prefer) and execute these command(s) –

sudo apt-get install openjdk-7-jre

(The package size is around ~30MB)

How to install JDK on Ubuntu 12.04

If you are a Java developer or a beginner, who just installed Ubuntu 12.04 LTS (Precise Pangolin) then JDK (Java Development Kit) is the first thing you want to install (although you might consider installing these essential things too).

In the previous version of Ubuntu, sun-jdk was also available – in 12.04 you might install it from an external PPA but it’s not recommended better try open-jdk or oracle-jdk (Oh!, I don’t recommend this either). So this post might help you in setting up Java development environment on Ubuntu 12.04 LTS.

Although, this post explains only about JDK but you may like to setup Eclipse (Most Popular IDE for Java programmers) IDE and Java server environments like Apache Tomcat, JBOSS or whatever depending on your project.

Installing JDK on Ubuntu 12.04 (Precise Pangolin)

In official package, v 6 as well as 7 is available. So if you’re already working on a project then you would obviously go for that, otherwise latest version is recommended.

If you don’t like command line interface then better go for synaptic package manager (above snapshot).
