Ubuntu 11.04 vs Mac OS X

Ubuntu 11.04 (Natty Narwhal) is the latest stable release (released few months ago, and it is the successor of Ubuntu 10.10>10.04 .. and it has arrived with a lot of surprising features).it’s the most popular Linux distribution among the desktop users and the community as well as users has augmented exponentially in the past few years. Ubuntu has established a new reputation among the common desktop users, because of its ease of use and simplicity. Before Ubuntu, Linux based distro were used only by computer ‘geeks’ but now, the Ubuntu is so simple that any non technical human can easily use most of its features (but it may takes some time (it depends on the users I.Q)). Ubuntu (The term ‘ubuntu’ has been borrowed from Africa which means ‘humanity for others’) is an open source software, released under GPL (GNU public License); available free for all Human. The word free doesn’t only mean that – ‘you don’t have to pay for it’ but also in other sense such as ‘you free to use it as you want i.e free also stands for freedom, there is no restriction!’. That’s why Ubuntu is well suitable for those who want higher degree of customization (Go ahead dude!, the only limit is your imagination).
Mac OS X is a closed source operating system developed by Apple Inc. Mac OS X is a unix like operating system comes by default with Macintosh computer. Mac OS X has very nice and robust GUI (Graphical User Interface) better than all other operating systems on this planet. The latest version – 10.7 (Lion, the successor of 10.6(Snow Leopard) released on August 28, 2009) in Xth series was released on October 20, 2010.

Ubuntu vs Mac OS

#1 Cost : Ubuntu is 100% free while Mac OS is not!

#2 Customization/Control : Ubuntu is better because it is an open source software, so it can be customized to any extent on the other hand Mac OS is a closed source software so a lot of restrictions are there.

#3 Usability : Even though, Ubuntu has made GNU/Linux a lot easier to use it’s still more complex than Mac OS. So Mac OS is better (The user interface is simply great in ease of use as well as for productivity) in this sense.

#4 Learning : Ubuntu is better than Learning because Linux distributions are well suitable for trying new things which eventually leads to serve as a better learning platform than any other on this planet (or may be universe, I don’t know :)).

#5 Applications : Ubuntu has a lot of applications with One click installation feature and most of them are free, while Mac OS do have some cool applications such as TextMate (An excellent text editor available only for Mac OS, TextMate is very popular among web developers and programmers because of its features and productivity; if you are an Ubuntu user then you can customize gedit to look like TextMate), but you have to pay for that and the options are limited because most of the developers target only Windows and GNU/Linux (while developing applications).

#6 Security : Ubuntu is more secure (after all it is a Linux distro) than the Mac OS X or any other non Linux distributions.

#7 Speed : Ubuntu 11.04 is faster than Mac OS X because Mac OS is focused mainly on how it looks not on how it performs; while Ubuntu is modular, focused primarily on performance and speed, and it has a lot of good looking desktops such as KDE, Gnome, Natty etc (if you think about the look and feel).

#8 Fun : Ubuntu is always fun because it has a lot of new stuffs/things to try you will never get bored. Mac OS is also Fun! but ??
Now it’s you who is going to decide the best! So get your opinion counted in the poll (see below) and share your views as well as experience through comment(s) (it’s not optional :)).


keyboard shortcuts

Ubuntu 11.04 keyboard shortcuts

Ubuntu is the most popular Linux desktop, the latest version ubuntu 11.04 (code name : Natty Narwhal) has arrived a month ago with a lot of changes, modification and surprises (such as Unity is now the default desktop in Ubuntu). If you’ve been using Ubuntu from long time then upgrading to Ubuntu 11.04, may not be a good idea as Unity is almost different and so you have to customize and learn new tricks as well as keyboard and mouse shortcuts for better experience.

Unity desktop has removed the bottom panel, which is helpful in accessing opened windows and other running applications, instead of that – it has a left panel  – Launcher (with auto hide features) seem almost similar to Dock Application but with some different functionality and 3D effects.

Why should you try keyboard shortcuts in Ubuntu?

Although an average computer user do not use shortcuts a lot but shortcuts can improve (a lot) the experience with Ubuntu (or any other Linux based distribution because all are 100% customizable) and it will also save a lot of time and effort, eventually resulting in better productivity. That’s the importance of keyboard shortcuts. Let’s consider an example – to open a terminal you will have to spend  3-6 seconds, if you don’t use any shortcuts, on the other hand if you use shortcut then 1-2 seconds will be enough; it means you saved 2-4 seconds in opening an applications…so finally you will save a lot of time if you apply this to some of your favorite applications or actions. The layout of unity also encourage us to use keyboard shortcuts, because there is no bottom panel is available from which we can select the apps window in single mouse click, instead of that first we have to move the mouse to launcher’s location, then launcher will appear, now we can select the desired apps.

keyboard shortcuts

Okay, lets come to the point – learn some cool and best keyboard shortcuts (these are default shortcuts, if you want you can customize/configure out in your way) that you can use in Ubuntu 11.04 with unity Desktop (although some of them may works with Gnome desktop as well as in older versions of Ubuntu such as 10.10 (Maverick Meerkat) or 10.04 LTS (Lucid Lynx)..just try (of course carefully) you will figure out in minutes).

Top 10 keyboard shortcuts for Ubuntu 11.04 Users

#1 : Ctrl+Alt+T => Opens a Terminal (Command Line or shell).

#2 : Super => Shows Unity Launcher (with Numbers indicated for each Apps) .       /* Super key => key with Windows Logo */

#3 : Super + {Number} => Opens corresponding Application (according to the number).       /* e.g Super+1 opens Home directory on my desktop */

#4 : Super+T => Opens Trash (Recycle Bin of Ubuntu).

#5 : Super+A => Opens the Application Lens.

#6 : Super+F => Opens the File and Folders Lens.

#7 : Alt+F2 => Run a command.

#8 : Alt+F1 =>Puts focus on a Launcher.

#9: Super+D => Minimizes or Restores all Windows

#10 : Ctrl+Alt+Numpad x => where

x = 0 : Maximizes the Window

x = 1, 2, 3….9 : Move the window to different location on the screen depending on the number, so focus on a window and try it.

I’ve explained only few simple keyboard shortcuts, if you know something extra then feel free to share with us – through comments!

JDK

how to install jdk on Ubuntu 11.04

Ubuntu (Latest Stable Version : Ubuntu 11.04 (Natty Narwhal) ) is one of the most popular Linux distribution on this planet while Java, the most popular programming language (Platform independent features makes Java Great! and superior to any other programming language, for building web and Desktop Applications). Due to a number of free( and of course they’re good) tools, compilers and other options Ubuntu has become the No. 1 choice, as a development platform, among the Java Developers (specifically young programmers).

If you are just a common user then you need only JRE (Java Runtime Environment) to execute java programs but If are going to write java programs or develop Apps then you need to install Java Development Kit (JDK, complete suite for Java Developers) along with some IDE like Eclipse or Netbeans (Not really necessary for absolute beginners). A lot of JDK’s are available, so if you have programmed before then choose the one you like, but on the other hand, try open-jdk-6, an open source Java Development Kit (contains Javac, an open source Java compiler and ). This post will explain – about installation procedure of Open-JDK on a freshly installed Ubuntu 11.04.

Ubuntu 11.04 vs Windows 7

Whether you are an Ubuntu user or a Windows user, this post is aimed to compare Ubuntu 11.04 with Windows 7 in every aspects… So let’s start a positive debate between them. Your view/idea is very important for this discussion so add your opinion through comments.

I ‘ve been using Ubuntu on my computer, from the last 2.4 years (Although I started with Windows Vista, and now I am using Windows 7 in triple boot mode, along with Ubuntu 10.10 (Maverick Meerkat) and 11.04 (Natty Narwhal) ), and I don’t Windows in general (exceptional case : like playing games). There are lot of reasons why prefer Ubuntu over Windows or any other operating system, and of course you will notice few of them, in the comparison table.

Update 1 : Two new rows added !

Update 2 : Two more rows added! (Thanks to Conualfy for his/her comment!)

Points Ubuntu 11.04 Windows 7
Control Since Ubuntu is an open source software, you can customize it as you want..There is no limit on the level of customization because the source code is available to use as you want (under GPL). it’s an proprietary software so forget about the source code and full customization.
Cost it’s completely free to use and distribute! Not free! No way, how can you think of that ?
Fun Ubuntu is complete fun! probably due to fact that there is always something new and exciting thing/stuffs try, just for Fun! You will get bored because there is lack of new things, so it feels like ‘got trapped in a box’.
Learning Ubuntu or any other Linux based Distros is excellent from learning point of view, specifically recommended for those who are interested in learning about modern Operating Systems (OS) and want to understand how it works. Forget about that, it doesn’t make any sense here.
Security/Virus STOP!!!  Ubuntu or any Linux based OS are virus free!, because it doesn’t work on the Ubuntu platform (probably due to the reason that most of the viruses were targeted to Windows and GNU/Linux is secure by default) so using ubuntu means that we are entering into the Virus free zone. Virus is one of the greatest threat to Windows based OS..and some one said – Windows and Security do not appear together – in a single sentence.
Diversity There is always new things waiting to try – e.g if you don’t like Gnome desktop, try something different such as KDE or XFCE or LMDE etc..it’s very flexible or in other words – modular. It has some desktop optimized for old hardwares while on the other hand you can enjoy 3D desktop effects with your new computer and graphics Card. There is nothing new on this side! choose something from the Menu and go on!!
Softwares A lot of free and open source software are available right there – in the Software Center or package Manager; just select and install in moments. Whether you are a student learning – “how to program” or a developer (desktop based software or web Apps), Ubuntu has better compiler (GCC, G++ etc), IDE(Eclipse, NetBeans), editors (gedit), Terminal (Bash) and all the tools you need. For programmers the apps are good but most common desktop applications – open office, Evolution Mail etc. sucks! Some proprietary softwares are good such as – Microsoft Visual compiler/IDE, Windows Live Writer, Microsoft word,One Note, Adobe Photoshop etc, but you can get an equivalent open source software for Ubuntu. E.g Gimp instead of Photoshop, Open Office in place of MS Word etc. In short, Windows has better commonly used Applications but a lack of programming tools and Apps. Windows Console sucks! (On the other hand bash Terminal is far better, powerful and Fun!)
Ease of Use GNU/Linux has very bad reputation if we consider this point (probably due to the fact that initially Linux based OS were used by only geeks who couldn’t think about non technical users), although Ubuntu is the most simple and easy to use – Linux based distro, it is difficult (for common desktop users) to use as compare to windows 7. File permission, root … irritates a lot to a normal desktop user. Windows 7 is very simple to use! as compare to Ubuntu 11.04 or any other Linux based distro.
Stability Ubuntu 11.04 or any other version of Ubuntu has very high frequency of releasing new versions which makes it very unstable and there are always a lot of crappy bugs waiting to fix. so it doesn’t seem  –  suitable for production/personal environment, even though LTS (Long Term Support) versions can be used in production environment. Windows 7 is very stable as compare to Ubuntu 11.04, so well suitable for production environment.
Drivers Compatibility Ubuntu has a lot of compatibility problems when it comes to device drivers e.g Graphics Card drivers, Webcam drivers… All device manufacturers releases the driver software for Windows 7 so there is no compatibility issue in this case.
