Getting time google.com

Some time setting up time using ntp server does not work in Ubuntu, especially when you are inside some kind of proxy. And setting up time manually may not be accurate and obviously you need to know time properly. But there is way in which you can set time using time stamp from google. Just open the terminal and run the following command. date -s "$(curl -sD - google.com | grep ^Date: | cut -d' ' -f3-6)Z" Hope this will help. Cheers A. Paul

Syntax highlighting for code in blogger

Introduction: There is no straight forward or simple way to do syntax highlighting to share any code through blogger. But we can easily do that by using some third party service. One such service is highligtjs.org . Use the following steps for code highlighting. Solution: We have to work in html view rather than compose view of blogger. For syntax highlighting we have to first add JS script for importing CSS in the header of the html. To do that add the following line at the starting in the html view. <head> <link rel="stylesheet" href="//cdn.jsdelivr.net/gh/highlightjs/cdn-release@10.2.0/build/styles/androidstudio.min.css"> <script src="//cdn.jsdelivr.net/gh/highlightjs/cdn-release@10.2.0/build/highlight.min.js"></script> <script>hljs.initHighlightingOnLoad();</script> </head> Then start writing inside the body html tag, as...

LyX not showing math font properly

Problem: I faced this problem after reinstalling Linux Mint on my computer. I simply installed the LyX, TeXLive and other LaTeX-related software. But when I started using LyX, it was not showing the math fonts properly. It was showing ‘a’ instead of ‘alpha’ or ‘b’ instead of ‘beta’, even though its corresponding latex code was correct, and the pdf output was correct. See the following figure for more clarity. Reason: One of the required packages of LyX is fonts-lyx, which is needed to visually display the math symbol in LyX. It was not automatically installed in when I installed LyX, and hence the math symbols were not visible properly. Solution: The solution is simple. Just install the fonts-lyx package from the package manager or from the command line. To install it from the command line, use the following command. sudo apt install -y fonts-lyx That’s all, this should solve the problem. Cheers A.Paul

Installing SciDaVis on Ubuntu 20.04

Image
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...
