How to export the datastage job in individual dsx


This script will export the datastage jobs into individual dsx files as sometimes, we need individual dsx to maintain the code version or syncing it with SVN.

Manually export of each datastage job is quite hectic and boring hence this script :-)

This script requires little bit information from you and set you free for your other chores

Prerequisites for this script -

1. Job List to Export
2. DataStage Client Installation Location
3. DataStage Credential

Mathematics in Markdown


From Wiki - 
Markdown is a lightweight markup language with plain text formatting syntax designed so that it can be converted to HTML and many other formats using a tool by the same name.[8] Markdown is often used to format readme files, for writing messages in online discussion forums, and to create rich text using a plain text editor(extensions - *.markdown , *.md ). website
Best thing of markdown files is you can convert the same into html without any issue. 



I've introduced with Markdown files when I have started to put my code on GitHub (https://github.com/atulsingh0). Started with little up n downs but after I've fallen for it, Its easy to write ReadMe or Math Equations files in markdown with little help.

In this tutorial, I have focused on Mathematics part only, for writing math formulas, Markdown is using LaTeX symbols for Greek letters, Brackets, Sign operator and lots of other symbols.

I have consolidated few of them and will add more,
Hoping, you will find it useful -  Direct Link

A Newer Version of Jupyter Notebook - Jupyter Lab


We all use Jupyter Notebook (previously known as IPython Notebook) a lot when researching on something or doing stuff on stuff :-)
For those, Who dont know what it is, It is a browser based Notebook which holds the Python code as well as executed Output. You can export it to html, pdf or its native format (*.ipynb).

So coming back to topic, there is a next generation of Jupyter Notebook is available, try it once, I am sure you will fell in love with it. So let's quickly check how you can get it -
Installation:
$ pip install jupyterlab

Execution:
$ jupyter lab

Features which I like the most:
1. You will get a file browser in left side of notebook window for easy access on files
2. Provide 5 quick access button at Leftmost panel (Files, Running, Commands, CellTools & Tabs)
3. Each Notebook will open in same browser tab, means there will be one browser tab and inside that tab there will be multiple jupyter notebook tab will open


For more details, visit - https://github.com/jupyterlab/jupyterlab
