Developing a web application with Lumen and MySql

Lumen is a new Php micro-framework developed by Taylor Otwell , the same author of the famous Laravel framework. I wanted to give it a try and I am here to share my experimentations. I am not an expert of Lumen (yet), but I think one of the best characteristics of this framework is that it makes really really easy to bootstrap a new project. So to prove this, we will now build a fully functional app backed by a MySql database in less than 30 minutes. Are you ready to start? A motivational quote…

Symfony, edit the Response globally using the Kernel Response event

One of the things I like most of the Symfony framework is its Http Kernel component . Not only it does offer a very straightforward abstraction to handle requests and responses in an object-oriented way but it also allows you to interact with the whole response generation process through events . This approach is very convenient and flexible and in fact the Http Kernel component is the foundation of the Symfony framework but also of several other famous frameworks (Silex, Laravel) and CMSes (Drupal…

5 lessons learned at the Bank of Ireland Accelerator

What a hell of 3 months! During the last 3 months I haven’t got a single minute to take care of this blog. I started a new adventure and moved to Ireland to attend the Bank of Ireland Accelerator Programme in Cork with my startup Sbaam . There I spent 3 incredible months with a huge amount of lessons learned about startups and entrepreneurship . I want to share with you 5 of the best quotes I heard from the mentors and explain what I learned from them. Consider this is my first “non technical” post with…

Simple echo server written in Go, dockerized!

In this post we will see how to write a (very) simple Go server app and how to put it into a Docker container and run it. Disclaimer : I’m an absolute beginner with both Go and Docker and this is just an experiment I did to start to explore this two interesting technologies. If you’ll find something weird or wrong you are very encouraged to scream at me in the comments ( Comments ), I will be extremely thankful ;) Introduction We are going to write a simple echo server in Go and then we will pack…

Transparent pixel response with Symfony, how to track email opening

If you have ever heard about ” transparent pixel ”, ” 1x1 blank pixel ”, ” tracking pixel ” or simply ” tracking image ” you probably know what we are going to talk about and can just skip to the implementation ! Introduction Transparent pixel image is a technique often used to track some user behavior (often visits or views to a certain online content) in scenarios where you can’t use javascript. One of the most common scenarios is probably email opening tracking. Can you put Google Analytics into an…

Introducing ORM Cheatsheet

This week I received an interesting email from Martin Stradej, the developer of ORM Designer , a tool to design ORM relationships with a simple but powerful graphic user interface. Martin wrote the mail because he wanted to acknowledge me of his latest project: ORM Cheatsheet . ORM Cheatsheet, as the name suggests, is nothing more than a reference website for those who struggles with some of the most common Php ORM libraries (it currently supports Doctrine2 and Doctrine , but it seems that Propel and…

3 invitations to try Atom.io

I have finally got my invitation to try the new text editor Atom.io . Atom is built with web technologies (node.js in it’s core) by the folks at GitHub and it’s somewhat very similar to the famous SublimeText . In my opinion it seems very promising (even if it’s significantly slower than SublimeText), anyway I have to try it a lot more before shaping a serious opinion about it. The point of this topic is that Atom.io is currently in closed beta and I have received 3 invitations to share with whom is…

Reset your MySql server password

Few days ago I learned an interesting trick that allows you to reset the password on a MySql server. This trick is pretty useful in case you have lost (or you haven’t ever had) the password of your MySql root user. You just need to throw some commands at the console. Note that I am assuming you are using Ubuntu or some other Debian derivate. Otherwise the commands may change a bit (but not to much I believe). 1. Stop the mysql daemon 2. Disable the security checks The mysqld_safe command will essentially…

Write a console application using Symfony and Pimple

In this article I will show you how to set up a stand alone command line application by using the Symfony Console component and Pimple . Writing console commands for Symfony (full stack framework) is easy and enjoyable. It helps a lot when you need to handle particular collateral tasks that are needed, in a way or another, to make your website running (processing and crunching data, make async requests, create reports, etc.). Anyway I discovered that writing stand alone command line applications using…

Integrating Twig.js and BazingaJsTranslationBundle

Recently I had the need to run a twig template that uses the filter on my frontend using twig.js , a pure JavaScript port of twig written by the good Johannes Schmitt . The JavaScript version does not handle all the functionalities offered by the original PHP version (even if it goes pretty close) and in particular it does not natively handle the filter. So, at first, I got a JavaScript runtime exception on my page when trying to use the template. Luckily enough the JavaScript version of twig is…
