Installing DBDesigner 4 on Ubuntu

The only way I found to install DBDesigner 4 on Ubuntu is as follows:

• Download the *.rpm file of DBDesigner.

• Download the library package and extract it using:

tar xzvf kylixlibs3-borqt-3.0-2.tar.gz

• After extracting it do the following:

sudo cp kylixlibs3-borqt/libborqt-6.9.0-qt2.3.so /lib/libborqt-6.9-qt2.3.so

Now your DBDesigner will be working, the executable file DBDesigner4 can be found at /opt/DBDesigner.

Found the solution on the following link.

Installing Adobe Flash Plugin on Ubuntu

Installing Adobe Flash Plugin on latest versions of Ubuntu (11 +) is straight forward and can easily be done by directly search and install from Ubuntu Software Center.

The problem comes when you are using the old versions of Ubuntu. Yesterday I have to install Ubuntu 9.10 on my system and got the problem of installing flash player plugin. After some searching I found the solution that requires enabling of repositories. Step by step solution is as follows:

• Go to "System > Administration > Software Sources" from the menu.
• Click "Other Software" tab and check the two options that represents the repositories. Selecting those repositories allows Ubuntu to download other softwares that includes adobe flash plugin as well.
• Go to  "System > Administration > Synaptic Package Manager" and search for 'adobe flash plugin'. It will give the package to install, you just need to select that package and click the 'Apply' button on the top.

Now you can run flash videos/games on your system.

Manually Install Erlang on Linux

Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of its uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance.

Applications that are built on Erlang also required Erlang's runtime for execution. Last week I got a chance to work on a Message Broker 'RabbitMQ' (will discuss it in other post) which is built on Erlang. So to get RabbitMQ Server installed on my machine I have to setup Erlang first. This post contains the steps for installing RabbitMQ Server manually on Linux machine. Following are the steps:

Get the Erlang package that you need to install

• In my case I have otp_src_R14B02.tar.gz

Unzip the package:

• tar xvzf otp_src_R14B02.tar.gz

Go to folder:

• cd otp_src_R14B02/

Following files may be required to install on your OS before running the configuration file:

If it gives gcc compiler error then install gcc compiler with following command:

• sudo yum install gcc gcc-c++ autoconf automake
• sudo yum install make
• sudo yum install ncurses-devel

For Ubuntu following command will be used:

• sudo apt-get install build-essential
• sudo apt-get install libncurses5 libncurses5-dev

Run cofigure File

• ./configure

After running the configuration file, run the make command on same folder:

• make

And in the and execute following command:

• sudo make install

This will install Erlang on Linux and it can be tested using following command:

• erl

It will show following lines:

Erlang R14B02 (erts-5.8.3) [source] [smp:4:4] [rq:4] [async-threads:0] [hipe] [kernel-poll:false]

Eshell V5.8.3  (abort with ^G)

My Experience of Installing MongoDB on Ubuntu

In my last post I have write some very basic and initial points related to MongoDB. That was my initial observation of what MongoDB is and what are its basic features.

This article does not contains the detailed step by step tutorial of how to install MongoDB on Ubuntu. There are already lots of articles available on the installation of MongoDB on Ubuntu &Windows operating systems. In this post I am going to write my experience of Installing MongoDB on Ubuntu.

There are two common ways of installing any kind of software on Ubuntu. One is by using the "Ubuntu Software Center" and other is to download the package and install it manually. Option one is commonly used by users as it is very simple and it automatically download and install the target software on Ubuntu. In the case of MongoDB both option can be used for installation.

For testing purpose I have installed MongoDB using the Software Center (you can also use apt-get command that also download and install package from Software Center). Initially it works good by using it from terminal. I can able to start and stop MongoDB and execute different types of queries. The problem begins when I try to use MongoDB programmaticaly. I cannot able to connect with MongoDB using Java and Eclipse IDE even MongoDB is running and can be used from terminal. So, I have removed all the packages of MongoDB and install it manually. After that I am able to use it via terminal as well as programmatically.

This seems to be something related to version issue as also mentioned on this link. If someone knows what is the actual reason of this different behavior on different installation options do comment here. This is what I have experienced when installing and using MongoDB on Ubuntu.

Open Transport Tycoon Deluxe (TTD)

TTD is one of my most favorite games that I have played and when I saw the 'Open' with it, I was really excited to install it on my Ubuntu OS.

The installation of Open TTD is difficult and you need to be a bit keera of shell scripting to do this job. I have followed all the steps on this link and managed to install OTTD successfully. After completing installation and launching the game I was really amazed by watching the same TTD main screen as what I was playing on my 'Windows OS' four years back.

The game is upgraded now and contains four different types of maps with each map containing different industries, disasters, vehicles etc. Maps are also really interesting with environment like a Desert area map, Snow area map, Toyland area map and a default one as well. I have some getty images of the game that are as follows:

All TTD lovers do enjoy this on your Linux OS.

Installing Virtual Box Guest Addition (Problem/Solution)

I have a VirtualBox-OSE installed on my Ubuntu from which I am running WindowsXP. The 'OSE' type of VBox that was installed on my machine is not much rich i.e. no pointer sharing between operating systems, no full screen display for Virtual Box's OS etc. I need to overcome these problems to make my working more easy.

After reading comments on different forums, I conclude that I need a 'Guest Addition' of VBox. So I have started to install the Guest Addition for my VirtualBox-OSE. I follow the same steps as mentioned on forums to install the guest version but always gets the following error messages:

Could not find the VirtualBox Guest Additions CD image file /usr/share/virtualbox/VBoxGuestAdditions.iso or /usr/lib/virtualbox/additions/VBoxGuestAdditions.iso. (i.e. it cannot able to find 'VBoxGuestAdditions.iso' file) Do you want to download this CD image from the Internet? And then it returns 404 :s

Now on one of the forum I found different information related to VirtualBox Editions: "There are two different Editions of VBox: PUEL and OSE. PUEL has a lot richer functionality but is available from proprietory Sun repositories. The GA are bundled this as an ISO. In the OSE version the GA are typically available as a separate virtualbox-ose-modules package."

The next thing that I have done is to uninstall the VirtualBox-OSE right away. I have downloaded the PUEL Edition of VBox and installed it. Now I have got the PUEL Edition, I can install the 'Guest Addition' on this VBox. The missing file 'VBoxGuestAdditions.iso' is now available in the folder. I doesn't have any issued in installing the guest addition after that. And finally have some rich features in my VBox.

NOTE:
=====

Executing Command-4 gives me the following error:

"IEs4Linux 2 is developed to be used with recent Wine versions (0.9.x). It seems that you are using an old version. It's recommended that you update your wine to the latest version (Go to: winehq.com).
You need to install cabextract first!
Download it here: http://www.kyz.uklinux.net/cabextract.php"


Actually here the error is not correct because i do have latest version of Wine but doesn't have cabextract.

You can install Wine easily from Add/Remove Applications.
If cabextract is not Installed go through the following steps:

Command 5: wget http://www.cabextract.org.uk/cabextract-1.2.tar.gz
Command 6: tar -zxvf cabextract-1.2.tar.gz
Command 7: cd cabextract-1.2
Command 8: ./configure
Command 9: make
Command 10: make install

Meld Diff Viewer

Meld is a tool which allows the user to see the changes in, and merge between, either two files, two directories, or two files with a common ancestor. I am using this tool in 'Ubuntu' as a replacement for WinMerge.



The tools is excellent and having user friendly UI. It also provides three way comparison between files and directories.

Look at some snapshots:
