SciDaVis is a free and open source application to visualize and analyze scientific data. This is kind of clone to the proprietary and commercial applications like Origin and Igor pro. This application can generate 2D and 3D plot and perform functions like curve fitting or Fourier transform. Problem The application is not available in the Ubuntu software center, so we can not directly install from Ubuntu repository. Solution: The latest version of the application is available on the GitHub, you can see it here. The easiest way to install the application is by using the prebuilt binary package. You can either download the deb file or install by adding the repo. I prefer the later because it will automatically update the application using the Ubuntu software update. The instruction can be found here. Go to the link, select Ubuntu and select Add Repository and Install Manually. Following are the command to install int in Ubuntu 20.04. sudo sh -c "echo 'd...

Installing Linux os like Ubuntu is very easy. But the problem starts when we lost all the already installed software. We install lots of software. Problem starts when we start to re-install all the required software. We can create a list of software and re-install them as stated in the previous blog post . But the problem is if we want to install third party software which need to add repo.

Then make the file exicutable by running the following command in the directory that contain the file. sudo chmod a+x i...

New version of Ubuntu comes on every 6 month with most recent version of software and with, up to some extend, new look. If we don't want to continue with the old version of software and if bored with same look we want install the new version. If you want to upgrade your system then it is ok. But if you want a clean installation then you have to install all your required software and you have to do all setting ones again. This is very tedious job. Here are some tricks to simplify the job. First you can generate the list of installed software by using this command, dpkg --get-selections > installed-software This command will create a text file name installed-software. You can edit this file and if you want remove some software by simply deleting the line containing the name of the software. Now when you are installing Ubuntu do not format the home folder. This folder actually contain all the settings of the software. And when you re install the software, in most cases, you w...
