Playing with Numbers and Variables in Python

By -
We will try to learn how to do declare number types (integer, floating points) arithmetic expressions in python.

Lets start:
First we will try doing simple arithmetic expressions on numbers :

For Addition, use '+'
For Subtraction, use '-'
For Multiplication, use '*'
For Floating point division, use '/'
For Integer division, use '//'
For a raise to b, use a ** b.

Lets demonstrate :


if you want to find the speed of a train, the formula is :
speed = distance / time

Instead of repeatedly using values, you can use variables, lets try it out :

And yes, you can use '#' to write comments
whatever you write after '#' will not be processed!!! :)

Writing your own ejabberd Module

By -
Coming soon: What is ejabberd? What is erlang? Installation details. I will start with writing the ejabberd module first. Once you have done all the installations: sudo make sudo make install sudo ejabberdctl start sudo ejabberdctl stop You can check the status using: sudo ejabberdctl status You can locate logs at: (With default installation) /var/log/ejabberd All config related changes will be mainly done at: /etc/ejabberd/ejabberd.yml You will need a basic understanding of erlang. You can take a short crash course at: http://www.erlang.org/course/course.html This is a good reference. Go to your ejabberd-15.07/src directory. This is where you will write the hook for your ejabberd server. Create a file, say mod_changeBody.erl. Your module name and file name should be same. Add the following basic contents into your erl file: -module(mod_changeBody). -behavior(gen_mod). -include("ejabberd.hrl"). -include("logger.hrl"). -expo

Conditional Flow - Spring Batch Part 6

By -
Jump to Conditional Flow using Custom Status There can be muliple scenario where you want your jobs to proceed depending on the outcome of your steps. For example, in case of our Corporate gifts shop, in case the automatic packaging of the gifts fails, we want some manual intervention to be done i.e. somebody should manually package the item.  IF-ELSE IF loop for packaging:     if packageStep fails                              then manualPackageStep                         else if packageStep executes successfully                              then sendOutForDelivery Entire code available at git repo:   https://github.com/ricsr/spring-batch-demo/tree/exercise_06 Using SpringBatch you can achieve it as follows: Create you manualPackageStep, which is very similar to your packageStep, except that it does the packaging manually. @Bean public Step manualPackageStep () { return this . stepBuilderFactory .get( "manualPackageStep" ).tasklet( new Tasklet() { @Override pu
