Over the years, software teams have questioned if PHP is a good choice for building web services. In this talk, I will share how we use PHP on the backend for Glu Mobile’s flagship mobile game Design Home, enabling it to regularly rank amongst the top free mobile games - both in downloads and grossing - since its launch in the Apple App Store and the Google Play Store in Q4 2016. Design Home reaches over 1 million daily active users, serving over 100,000 requests per minute while maintaining a user base of over 30 million players. To date, over 1 billion designs have been made by players. We will deep dive into the thought processes, development, testing and deployment strategy, showcasing what we have achieved with PHP and why we love it and rely on it. My goal is to share with the community that, when done the right way, PHP can be used to build and maintain reliable, massively-scalable and high-performance backends using web services. See Less

15 years ago, plain text password storing was normal with some using MD5. We look back now and wonder what we were thinking! With GDPR and people thinking more about personal details, its about time we caught up and started storing them securely. There are many uses for personal data and is often sought after by criminals for targeting people. How can you prevent your customers data being used in these attacks ? Encrypting your database is a fantastic way! PHP is the first language to have modern encryption built in to the core, This talk will show you how to use these methods to allow your data to be secure and also not lose the speed which you can currently search for this data in your application. This talk will touch on architecture and will be focused on MySQL although the same techniques can be used for any storage engine. See Less

You say "toolbox", I say "treasure chest". We work on the web building so much more than web pages but these rich, asynchronous applications can suffer from ailments that are difficult for us to see. This session is a tour through some of the best tools around for working with HTTP to observe interaction between components and diagnose problems. By knowing the tools at your disposal and the right job for each, you will be able to quickly and painlessly identify and fix HTTP-related problems - and then get to the pub on time! I mean, get the next thing done ;) Whether you're debugging a backend API, an asynchronous client request or an unexpected timeout, these are the tools you will want to have at hand. See Less

The blockchain is a hot new topic in the technology due to the rise of various cryptocurrencies, Bitcoin being a most prominent example. How does it work? What advantages does it give? What problems do they solve? What problems can be solved that way? I want you to dive with me into the immutable world of blocks where I will explain everything, from a simple hash, through Merkle trees, up to implementing your own blockchain. See Less

Our job might be to build web applications, but we can't build apps that rely on networking if we don't know how these networks and the big network that connects them all (this thing called the Internet) actually work. I'll walk through the basics of networking, then dive a lot deeper (from TCP/UDP to IPv4/6, source/destination ports, sockets, DNS, switching, firewalling and even OSPF, VRRP and BGP). Prepare for an eye-opener when you realize how much a typical app relies on all of these (and many more) working flawlessly... and how you can prepare your app for failure in the chain. See Less

In this presentation we will look at storing complex data in a single field. Many noSQL solutions are created around this (such as Redis’ lists, sets and hashes; MongoDB’s records), and many relational database now also support storing complex data in a single field through specific data types (such as PostGreSQL’s JSONB or hstore). Each of the different database engines support different things, and handle these data types in different ways. In this session we compare the different approaches to storage, indexing and interactions with these data types in different databases. See Less

Kubernetes is a very powerful container orchestration platform that is quickly gaining traction and gives you lots of benefits in deploying, running and scaling your microservice web application. But it has also a steep learning curve. In this workshop you will deploy and scale your first application which consists of multiple Micro-Services to Kubernetes and learn how you can use Persistent Storage. If you want to not just watch, but also program along yourself, have Git, Docker and the Kubernetes CLI kubectl as well as a IDE or Text Editor of your choice installed on your system. See Less

Automated testing is an incredibly useful tool for any developer. From emerging design with unit tests to preventing regression bugs with acceptance tests, getting a computer to run tests instead of testing manually is a huge step forward and saves vast amounts of time. Where do you start with automated testing? It's an intimidating topic and can be confusing to understand what all the techy speak means, let alone how you get going. But writing automated tests shouldn't be difficult, and can and should be part of your daily workflow once you understand exactly what to test, and how to test it. In this workshop, we'll introduce WHY and HOW you can get started with unit and acceptance tests, and touch on integration testing. By the end of the workshop, you'll understand how you can leverage automated testing in new and existing projects, and be ready to save time and energy when developing. See Less

Since it's founding, Tebex has processed over 18 million payments for games servers around the world. This is a rich data source, and one that we've significantly under-used. We know there should be ways of using this data to improve our product and to make our merchant's lives easier - how and where to start, now that's a totally different question! Join Liam as he shares Tebex's initial experiences in experimenting with machine learning to use past data to prevent fraud in the future - different algorithms we've tried, (many) failed experiments, the situation today and plans for the future.

Microservices are the latest architectural trend to take the PHP community by storm. Is it a good pattern? How can you use it effectively? In this talk, we'll explore real world experience building out a large scale application based around microservices - what worked really well, what didn't work at all, and what we learned along the way. Spoiler alert - we got a lot wrong. See Less

The talk aims to highlight the importance of testing, why developers must spend more of their time testing, how testing generates more robust applications and why testing makes developers' lives easier. The talk is based around a live coding demo. The talk will: Explain the difference between tests that prove an application works and tests which aim to break the application logic - Highlight how test to break principles force developers to introduce logic to handle unexpected behaviour - Show how test to break principles result in more robust applications as developers write code that can only be used in one way - Encourage developers to apply test to break principles to all types of tests, including manual tests.

There are a great many reasons your application can benefit from moving to the cloud, but enough requirements for retraining, uncertainty around cost or complexity and just plain worry about what can go wrong to delay or prevent such a move. When my business moved to the cloud we learned that there are ways around many of these challenges, allowing you to move your application in a way which might not be best practice but which works and gives you a solid platform from which to advance and improve your cloud implementation. In this tutorial we'll look at key building blocks to put a LAMP application onto AWS, what might cause problems for your individual use cases and how to mitigate these. As well as basic plans to get you started we'll look at pathways to modify your application and train your team to take more advantage of cloud native features and adhere to infrastructure and security best practices in a way which allows you to keep running your team and your business.

Knowing how to do things right is half the battle. Knowing how to do the right thing is the under appreciated but essential other half. In this workshop we'll learn how to discover the language of our clients. We will gracefully evolve our understanding from nothing to something and use various modelling tools to grow our understanding of the problem. If you want to have better conversations, make more useful models, and have the optimal preparation for writing code, then this is the workshop for you. Topics include context mapping, event storming, and value mapping. See Less

After days, weeks, or months of coding many developers don’t know how to gauge the quality of their code. I’ll introduce tools to grade, benchmark, and analyze PHP code in an automated fashion allowing developers to write better quality software. Then I’ll explain key metrics to help understand what may need to be refactored, and use code smells to point out bugs before end-users discover them. Attendees will see how to use these tools, know where to find them, and be able to implement them in their own workflows. See Less

Alice and Bob have covered the basics of secure communication but cryptography can offer us more than this. After a brief refresher on the basics, we'll take a look at some of these other aspects of cryptography including hash functions, elliptic curves and quantum cryptography. Then we'll take a look at some practical applications answering questions such as: can I trust a web of trust? or should I use a block chain for this? See Less

Continuous Delivery Pipeline as code is key helping you to ensure long term maintainability. Treating your pipeline as code helps you to version it in your SCM of choice, makes changes easily traceable and lets anyone on your team make required changes. In this session I will show you how we build and maintain our Continuous Delivery pipeline using tools like GitLab CI, Docker, Nexus and Traefik. Together we will take a deep dive into the GitLab CI Build Pipelines to build and deploy docker containers to dev, stage and production environments. See Less

Learning more than one programming language is key to becoming a better developer. It is like adding a new tool to your toolbox. The more tools you have, the easier and quicker you’ll be able to tackle whatever job you need to do. You’ll also be able to use the right tool for the job, and who doesn’t like that?! I picked up Go (golang) a few years ago as it was becoming more popular among developers. Coming from a PHP background, I had no idea what channels or goroutines were or how is concurrency different from parallelism. I’ve got to say, it was a whole new world. Very different, but very cool. I was hooked! By happy coincidence, my company was looking to rewrite a legacy PHP app in Go. It was over 2000 lines of procedural and messy PHP4 with more downtime than I’m willing to admit to. I took on this project, and soon enough we had a much faster, more maintainable and much more reliable app for our customers. Go gave us options we would not have in PHP. The goal of this talk is to give you a good idea of what Go is and how it compares with PHP. We’ll look at the language itself as well as the tooling and communities around it. Even if you’re not sold on Go by the end of it, I hope you’ll leave inspired to go out there and learn whatever language you wanted to look into next. See Less

Keeping your environments in sync has been a challenge for software development for a long time. Developers tend to install their own versions of languages, databases, services etc. Doing so manually results in not only inconsistencies between dev and prod, but also from developer to developer, resulting in the always wonderful ""It works on my machine"" syndrome. Various tools have strived to solve this problem: MAMP, XAMP, VirtualBox, Vargrant, Puppet, Chef, homestead, etc. These are all steps in the right direction, but they're often heavy and require developers to learn new skills to work with them. In this talk, I'll be showing you how to Dockerize a new or existing project in such a way that the developers that use the project barely even know they are using Docker. Getting a new dev up to speed on a new project with a factory fresh machine is literally just a matter of installing Docker and check out the source code. That's it! Some of the benefits you'll see from using this approach:

• Onboard new devs in minutes.
• Have projects with unique (often incompatible) dependencies on a single machine.
• Dockerized environment that acts like natively installed tools
• Version locking of the tech stack
• Updates to dependencies automatically distributed to other developers
• Easily extended into CI/CD"

This prototype works, but it’s not pretty, and now it’s in production. That legacy application really needs some TLC. Where do we start? When creating long lived applications, it’s imperative to focus on good practices. The solution is to improve the whole development life cycle; from planning, better coding and testing, to automation, peer review and more. In this tutorial, we’ll take a deep dive into each of these areas, looking at how we can make positive, actionable change in our workflow. This workshop intends to improve your skills in planning, documenting, some aspects of development, testing and delivery of software for both legacy and greenfield projects. The workshop is made up of multiple exercises, allowing dynamic exploration into the various aspects of the software development life cycle. In each practical exercise, we'll brainstorm and investigate solutions, ensuring they are future-proofed, well tested and lead to the ultimate goal of confidence in delivering stable software.

Database joins can be expensive and you can reduce dives into the indexes/data by using JSON columns. By loading data kept in smaller 'stub' tables into main tables it is possible to minimize joins for simple data like address, phone numbers, and the like in schemaless JSON documents. Yes, third normal form or better has advantages at many levels but it is a design that is costly for many-to-many relations! It is very easy to refactor data is is often stagnant or infrequently updated to take advantage of hybrid SQL/NoSQL databases to greatly increase overall query performance plus increase code readability. This approach can completely change your ideas on data architecture and provide easy mutability for future changes. See Less
