I almost use only the command line to make calls on APIs using cURL. It's convenient and fast, easily scriptable if needed and the history of bash saves me time. But the response provided by cURL is not always readable especially when it comes to JSON. In this article I will introduce JQ that I use to display a pretty readable JSON and more. Read the post

Writing unit or functional tests on code has almost become a standard. Having a server that automates the verification of these tests and deploys the code is the goal of many development teams. Despite this, these good practices are rarely implemented for database schema migrations. In this article, I'll show you how with a little bash and Jenkins, I test and automate my SQL migrations.

Controlling this is unfortunately not systematic, and particularly seldom automated. I'll show you in this post how to automate this control using SensioLabs' tool and Jenkins. Read the post

Sometimes the processing of a message causes an error. In this case, it is common to move this message to another queue to try to process it later.

Following the article on the manipulation of dates in SQL, I realized that, in fact, the manipulation of date in php was not so simple and known as that. There are many functions on dates in PHP and I still find a lot of code that gets confused trying to calculate dates with mktime, manipulating timestamps. While a very practical class exists: DateTime. So it is she, and her companions, that I will present. Read the post
