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.

Kong docker container exits with 132 error code without any message

Docker Container Exited (132)

I was building entire Devops environment with ansible automation and suddenly Kong stack didn't start properly.

 The problem was that the Dev server was old Dell Server and it doesn't support "sse4_2" feature from CPU.

What is SSE Technology?

SSE is a processor technology that enables single instruction multiple data. ... SSE is designed to replace MMX™ Technology. It expanded over the generations of Intel® Processors to include SSE2, SSE3/SSE3S, and SSE4. Each iteration has brought new instructions and increased performance.

Information from CPUInfo


 [root@dockerdv01 ~]# cat /proc/cpuinfo | grep sse4_

Old Dell Server supports only sse_4_1 and this was the issue. After moving to new server which supports sse4_2, Kong deploys properly

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

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"        <
