Create simple TODO app AngularJS with bootstrap and Spring MVC
In this postwe will show how to create simple TODO application which consists of two main parts.
1. AngularJS GUI client
2. Spring MVC war file as backend for this applicationFirstly, we will consider GUI client build on AndroidJS framework.
In Front-end we consider two views and two controllers. First view and controller is for manipulating with login logic and second for showing and retrieving data from server (our backend).
We will use bootstrap framework as our base style, because we want to create responsive design with idea „mobile-first“. Keep in mind that we are not focusing on great design. -
Colors in shell console
Great examples of colors in console or terminal is described in ASCII-TABLE.COM.
For me, the most usefull were these informations:Esc[Value;...;Valuem Set Graphics Mode: Calls the graphics functions specified by the following values. These specified functions remain active until the next occurrence of this escape sequence. Graphics mode changes the colors and attributes of text (such as bold and underline) displayed on the screen. Text attributes 0 All attributes off 1 Bold on 4 Underscore (on monochrome display adapter only) 5 Blink on 7 Reverse video on 8 Concealed on Foreground colors 30 Black 31 Red 32 Green 33 Yellow 34 Blue 35 Magenta 36 Cyan 37 White Background colors 40 Black 41 Red 42 Green 43 Yellow 44 Blue 45 Magenta 46 Cyan 47 White

update .properties file with sed
in previous post we have mentioned how tu use sed link
in this short tutorial we will show how to edit .properties files using sed
lets consider this short properties file
java.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactory java.naming.provider.url=http-remoting://localhost:8080 jboss.naming.client.ejb.context=TRUE
yes it is jndi.properties BTW
now we will use this sed script to update file
sed.exe -ri "s/java.naming.provider.url.*/java.naming.provider.url=http-remoting:\/\/127.0.0.1:8080/" jndi.properties
command i is for insert to the same file and r is for using special expresions like “^”
remember to escape special charactersafter this script was executed content of jndi.properties is showed below

recursion in postgresql with working example
recursion in postgresql is defined with key words “WITH RECURSIVE”.

WITH RECURSIVE t(n,m) AS ( -- this is CTE SELECT 5 AS n,5 AS m -- something like n=5 UNION ALL -- this is needed for "join" iterations SELECT n-1, (n-1)*m FROM t WHERE (n-1)>0 -- for every iteration do value-- and make multiplication ) SELECT MAX(n) AS NUMBER,MAX(m) AS factorial FROM t; -- finally show result
