From this blog, typescript feature will be added. There are couple of ways to implement static type checking like; flow from facebook, PropTypes and Typescript. Typescript is well integrated with Visual Studio Code and supports better linter, error messages, and intellisense.

Add DNS using network manager in CentOS

Adding DNS using network manager in centos

If you change DNS by yourself from /etc/resolv.conf, the configuration will be gone after rebooting the computer.

Assuming to run all commands with "root" account. Otherwise, the command should be run with "sudo" in front of each command

1. Find connection
# nmcli con
NAME    UUID                                  TYPE      DEVICE
ens160  4f1de527-4257-467d-8476-c5c6efdf1c74  ethernet  ens160

2. Update DNS entry
Format nmcli con mod ipv4.dns dns_servers
# nmcli con mod ens160 ipv4.dns "8.8.8.8 8.8.4.4"

3. Restart network
# systemctl restart network

After update DNS entry, check /etc/resolv.conf file and you will see the new updated record.
# cat /etc/resolve.conf

Replacing text in PDF file using iTextSharp

ReplacingTextUsingITextSharp title: Replacing text in PDF file using iTextSharp tags: - PDF - Replace Text - iTextSharp date: Nov 11, 2016 Overview I’ve trying to replace text in PDF file and this is most simple way to replace text in PDF files. Before approaching this, I’ve tried to replace text using command toolkit with pdftk, qpdf to decrypt, and sfk181 to replace string with new, but this approach faced couple of issues; 1. font, 2. text area size. After long investigation, this may be easy way to replace text. Put white colored rectangle on top of string and stamp text on the location like erase text using whitner and write on top of it. Tools Visual Studio 2013 C# iTextSharp Code using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using iTextSharp.text.pdf; using iTextSharp.text.pdf.parser; using iTextSharp.text; using System.IO; namespace EMTechnicalDieline { class Program ...

Using GIT(Bitbucket), Visual Studio Code

Concept of Git Git has two repositories; local and remote. Two different commands type to commit the changes; 1. commit/add: load/save changes to the local repository. 2. push/pull/clone: load/save changes from/to remote repository. How to setup remote git server , bitbucket , with Visual Studio Code To use git, I downloaded it from [git-scm](“ https://git-scm.com/downloads “) and installed with bash mode to keep the comparability for different platform. Set up remote repository * Create project from bitbucket. In this case, I created “blogmarkdown”. Remember the URL for the git repository. To find out the repository, just add “.git” at the end of the URL from bitbucket. For me, it will be “ https://alexjoh@bitbucket.org/alexjoh/blogmarkdown.git ” Link the remote with local folder * Create local folder. In my case, I created d:\gitrepo Initialize git local repo. Change the folder to the gitrepo and run git init If there are existing files from a remote git re...
