Paying for goods with Bitcoin is becoming more and more popular. If you run, maintain or develop an e-commerce website, ICO project, exchange, or trading system, you may be interested in a quick way of integrating with the Bitcoin blockchain.
This article will show one of many ways of installing a Bitcoin mining software and integrating a PHP application with it. I will present how to generate an address for your users and check if the transactions are confirmed.

During my journey with the cryptocurrency, I realized this is a common problem to find a highly qualified programmer who used to work with the cryptocurrency network. This is like finding a big panda in China – they are super rare. So, finally I was called a big panda and because I like to have some big panda friends, I decided to share the knowledge and my experience.
I will create a set of articles about the blockchain, the idea and general view, cryptocurrency – the Bitcoin, the Ethereum (including smart contracts), EOS (new fancy cryptocurrency that may be a trendsetter next year) and all troubles and problems that we faced.
From my personal experience, it came that the blockchain idea is both – technical and intricate. Coding without a strong knowledge about the background and idea of the blockchain brings to a lot of confusion and misunderstanding. Let’s start with the idea.
PhpUK is a conference I have wanted to attend for a long long time. I had watched all the videos on youtube really carefully for the last few years and always got this weird feeling this might be one of the best and most important conferences in Europe. So, here I am.
3 totally different paths available for attendees made the choice of my own quite difficult. Sometimes, I had to skip presentations I wanted to see, because they were happening at the same time as those I wanted to see even more. From time to time, I was bored. But, at the end, I have created my own track and I am happy with the result. If you do not have the time to watch all the presentations online, and it does not matter if in video or slides format, then I would be happy to share my totally subjective choices.
I have spent a lot of time watching presentations about automated deployment with Ansible, Capifony, Capistrano or making consistent environments with Vagrant or VirtualBox, but all of those presentations did not tought me how to build environment from scratch, to achieve complete continuous delivery system. And that’s why I decided to create a series of tutorials in which we will configure a virtual machine, join the configuration to the project, automatically deploy and connect everything together with a continuous delivery tool.
A couple of weeks ago I have discovered a new service – the livecoding.tv. It is a livestreaming platform where people code products, live. They connect people around the programming languages that they love. Streamers are a mix of professional engineers, students and hobby coders. So, I have decided to join the community and broadcast own live video or videos.
Two days ago I have published a post at X-Team blog about achieving continuous deployment process. To do so, I choose the Docker for visualization, AWS Elastic Beanstalk as a delivery environment and Codeship as continuous integration system.
The tutorial is created as a video screencasting starting from a basic Symfony application and and carried us to the fully automated environment. We start from configuring Docker on local machine, preparing the integration with Amazon Webservices and automating the deployment with Codeship.
Contributing the open source is a topic raised time and again on blogs, during conferences, meetups and barcamps.
This happens because of several reasons – many programmers want to be involved in extraordinary projects, create
useful solutions or leave their marks on a masterpiece of software.
This topic’s stayed in my mind for a while. Inspired by Joshua Thijssen’s presentation from PHP UK about (re)discovering the SPL in PHP, I decided to investigate this more carefully. I have to admit that took me some time to understand how the things work and how to not misunderstood the purposes of each iterator and because of lack of documentation it wasn’t that easy. I did a couple of mistakes and probably I will do more, but as Joshua said in his presentation:
The documentation of SPL is completely useless. What can we do? Blog about it!
The second day was a pretty funny for me. This one started when I left my friends and had gone to listen to presentations and they chose to eat breakfast instead. I think this happened just because of hunger – I decided to write to Anne Sophie and make a presentation during lighting talks. Crazy, huh? But, I’ll talk about this later, because a lot happened meanwhile.

Yesterday, me and my fellows from @XSolve arrived to Madrid at SymfonyCon Madrid 2014 conference. It’s the greatest and finest Symfony’s event in the year. A lot attendees came to listen about Symfony as a framework and as a success story.
