Create table in PowerShell

Sometimes we need to have a CSV in output of the script. The manual concatenation of string is not a beautiful solution for object-oriented PowerShell. The easiest way to create the table and export it to CSV for me :

Check the size of AD Connect MS SQL Express database

MS SQL Express has database size limit of 10 Gb, so how to know when to switch to another edition of MS SQL?

To check current database size of AD Connect you can use following commands:

You can also connect to ADSync database with Invoke-Sqlcmd cmdlet from SQLPS PowerShell module:

Python 3.5 Essentials – 1. Output

When you are trying to learn a new language it is always better if you will see a practical real life result. Let’s try to learn Python from zero and develop a chess game.

The first topic to onboard is Output, because it is the only one way for human to get a result of program execution. For our first programs we will use a text output on screen to console (terminal).

For this series of articles I am using Ubuntu 16.04 where Python 2.7.12 and Python 3.5.2 are preinstalled.  I will write an article to make an instructions for using examples on Windows.

To print some text on the screen we should use print() function in Python. You can create chess0.py text file with following code:

To run this code, open console and type following command:

Now, Python 3.5 will interpret your code and print the chessboard on the screen:

Usually any console is using monospaced fixed-width fonts, so, all characters should be well aligned.  But i=even if we can understand the figures it does not looks like a chessboard. To make it more realistic we can use escape sequences. Now you can modify your code to add right background colors for chessboard cells:

Run python3 again:

chess1

Now, it looks nicer but our code became unreadable. How to make it better with help of variables we will cover in the next article.

Congratulations with your first program on Python 3.5!

 

Arrays and objects in ARM Templates

Please, review the article about ARM templates before : Authoring Azure Resource Manager templates.

Before thinking about Nested templates that is possible to imagine a lightweight scenario based on standard ARM template capabilities. Types of variables and parameters in ARM template are not only scalars and they can represent objects and arrays.

Template parameters can take as an input object, array, and secureObject. Variables are type agnostic. Grace to JSON, syntax for those types using is mainly defined by JavaScript Objects and Arrays.

AMQP Filter for Azure Event Hubs with Apache Qpid Proton

There is no a lot of documentation and examples how to deal with AMQP filters by using qpid-proton (Proton C API).

Deffierent approaches for working with Azure Event Hub are well described by the following link: Using Amqp.Net Lite with Azure Service Bus Event Hubs.

In my practice I’m using qpid-proton 0.8. To set the filter for retriving messages from Event Hub by timestamp offsset:

You can get binaries of qpid-proton 0.8 as NuGet package which are compiled for processors with IA32 instructions set (I need it for my Intel Galileo Gen2 projects).
