Learn the basic concepts of Doctrine ORM, implementing the Data Mapper pattern with php.
In the previous article we saw how to perform the preliminary steps to prepare our working environment, create an Ebay developer and a sandbox account and generate the keys and credentials needed to execute API calls. In this new chapter we will create our first request and perform our first call focusing on the “Finding API”
In this tutorial you will learn:
How can a program make a decision? Can a program choose between two or more options. Actually, it can. This isn’t some kind of advanced AI concept, it’s just a matter of evaluating whether or not certain conditions have been met and choosing a response.
The way that a program can evaluate a condition comes down to true and false. If something is true, do this. If it isn’t true do, that. The if statement is the structure for a program to pose these questions and evaluate whether or not they are true. if statements can check multiple conditions and provide multiple responses. They can be used to divert code down one path or another and control the overall flow of a program. They can also be used as a gating mechanism to determine whether certain blocks of code run. Have you ever gotten a message telling you that you needed to log in to continue? That was the result of if.
This is the third article of the series dedicated to Ebay APIs and their use via python. In the first article we saw how to setup our working environment, creating a developer and a sandbox “test” account, generating our API keys and installing the python SDK.
In the second article we approached the Finding API, focusing on the findItemsByKeywords call. In this article we will introduce the Trading API.
In this tutorial you will learn:
AddItem API callThis tutorial covers advanced python concepts such as Python classes, constructors, encapsulation, inheritance, polymorphism and creating Python packages and modules.
Therefore, if you do not have any prior Python knowledge we refer you to our Python Fundamentals Tutorial.
The Ebay Merchandising API is the focus of this fourth and last article of the series dedicated to python and Ebay APIs.
This API provides less calls than the ones we previously saw, but among them, one that can be very useful: getMostWatchedItems: we will focus on it.
In this tutorial you will learn:
The JSON (JavaScript Object Notation) format is widely used to represent data structures, and is frequently used to exchange data between different layers of an application, or by the use of API calls. We probably know how to interact with json-formatted data with the most used programming languages such as parsing JSON with python, but what if we need to interact with it from the command line, or in a bash script? In this article we will see how we can accomplish such a task by using the jq utility and we will learn its basic usage.

The following post is a little bit different from my other posts as it does not solve any of your Linux configuration problems. Apologies there! This post is an attempt to kill multiple birds with one stone, hence expose children to a command line, avoid web flash and ads driven multiplication practice tests online and most importantly gain some multiplication skills along the way.
My daughter reached the age where she is required to perform multiplication calculation at school. So together we have developed a below Bash script to take her 1×1 to 10×10 multiplication tables practice to the next level. She approved all the output colours with a “cool” mark, and to my surprise, she was very quickly able to correct my forgotten closing quotation marks during the development thus significantly improving development efficiency:-)
Learn to know the different type of joins and how to use them working with mysql or mariadb databases
In this series of article about Ebay APIs and their use via python and the Ebay python SDK, we see how to setup our working environment and work with the Finding, Trading and Merchandising APIs.
We all very often use bash scripts to automatize boring and repetitive tasks. Sometimes in our scripts we need to ask
the user to perform one or more choices interactively: in this tutorial we will see how to use the Bash shell select statement to perform such operation in very few lines of code.
In this tutorial you will learn:
Our objective is to make a dummy query execution run faster on PostgreSQL database using only the built in tools available
in the database.
PostgreSQL server base install up and running. Access to the command line tool psql and ownership of the example database.
