Build React Native App (4) - Redux, Jest, and NativeBase

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.

ssh can't connect to remote due to REMOTE HOST IDENTIFICATION HAS CHANGED

SSH can't connect to remote: "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!"

After rebuilding the remote server, ssh can't make connection to remote server with following messages

λ ssh -o ServerAliveInterval=60 root@10.202.0.150
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
SHA256:cESEZr5cIIDf+uqksrYo+G34m5xm3gu6irysqQbLGN0.
Please contact your system administrator.
Add correct host key in /c/Users/alex.joh/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /c/Users/alex.joh/.ssh/known_hosts:13
ECDSA host key for 10.202.0.150 has changed and you have requested strict checking.
Host key verification failed.

Solution is regenerating the key with ssh-keygen

λ ssh-keygen -R 10.202.0.150
# Host 10.202.0.150 found: line 13
/c/Users/alex.joh/.ssh/known_hosts updated.
Original contents retained as /c/Users/alex.joh/.ssh/known_hosts.old

C:\Users\alex.joh
λ ssh -o ServerAliveInterval=60 root@10.202.0.150
The authenticity of host '10.202.0.150 (10.202.0.150)' can't be established.
ECDSA key fingerprint is SHA256:cESEZr5cIIDf+uqksrYo+G34m5xm3gu6irysqQbLGN0.
Are you sure you want to continue connecting (yes/no)? yes

Export folder structure to file on Windows, Mac, and Linux

Introduction Most time, I make screenshot to show folder structure, but whenever there is change, it is painful to make screen capture again and agian. This is how you can export folder structure to text file. Tree on Windows "tree.exe" is installed as default and you can run it from command prompt. d:\GitRepo\github\dockeransible>tree /? Graphically displays the folder structure of a drive or path. TREE [drive:][path] [/F] [/A] /F Display the names of the files in each folder. /A Use ASCII instead of extended characters. d:\GitRepo\github\dockeransible>tree d:\gitrepo\github\dockeransible /A /F > tree.txt d:\GitRepo\github\dockeransible>notepad tree.txt d:\GitRepo\github\dockeransible> Output from the command Folder PATH listing Volume serial number is D8A7-163B D:\GITREPO\GITHUB\DOCKERANSIBLE | README.md | tree.txt | +---2-CreateVM | CreateVM.yaml | +---4-AnsibleDebug | DisplayClonedVMInfo.yaml | +---5-Ad

Adding SOAP Header generated by JAXB(wsimport)

Adding SOAP Header generated by JAXB(wsimport) Introduction Recently, I've been working with Exact Web Service and needed to add SOAP header entry from the source files generated by wsimport tool. To access Globe database, I needed to add database server name and database name from SOAP Header. I tried to find out lots of article and this is the way to add headers into SOAP.

Sample application for Active Directory SSO with Spring Security 4 and Waffle

Image
Introduction I've developed quotation program with Mybatis, Spring MVC, and SQL Server, but I had a request of integrating this module with Spring Security and Active Directory. I've researched about possible solutions and I've spent quite bit of time with Waffle and SAML. SAML is more ideal, but I found out that the entire implementation is too complicated and I decided to use Waffle for this purpose. One of drawback of Waffle is that the Tomcat server must be runned from Windows platform. I tried to find out spring security example with Waffle, but it is hard to find out the sample from Internet. It took so many hours to create this simple example. Tools Spring STS: 3.6.4 Spring Security : 4.0.1 Spring framework: 4.x.x Waffle: 1.7.4 Implementation Creating Spring MVC Project Create New Project -> Spring Project -> Spring MVC Updating POM To make easy of managing version, added two versions under "properties"        <
