Hello from organizers

Our experience from an attempt to develop a startup in 24 hours. The development advantages and disadvantages of this approach.

HHVM is a new implementation of PHP backed by a powerful interpreter and a JIT compiler. Hack is a new programming language targeting HHVM which augments PHP with a type system, proper closures, async capabilities, and many more. The talk will give a high-level overview of the features of both, outline the benefits of the alternative execution model brought by HHVM, and possible day-to-day benefits introduced by Hack.

Is your domain full of events that are happening as users are doing stuff? Why not have them in your system? You'll be describing the real world of your domain better and easier. And you can get surprising benefits. Come and see how.

A short introduction into the world of tutoring and general writing for the greater good of the PHP community and, of course, profit. Learn some interesting insights about the community at large and find out about the educational side of PHP, passive income, and monetization of knowledge. As a bonus, find out some gender, age, location and other stats of the readership of one of the most popular online PHP magazines and play with the raw data yourself.

Forget about classic website where UX is not so important. We are living in time where usability is one of the important thing if you are building some business client oriented web service. How to connect Symfony2 as backend and AngularJS as frontend solution? What are best practices? What are disadvantageous? How to take best from both worlds? These are topics I will cover in my talk with real examples.

Everyone starts with a simple one-machine setup, running PHP(or whatever else you fancy), MySQL/PostgreSql and Apache/Nginx. Sooner or later that will not be enough, and you will be faced with some important architecture decisions. This talk will show you how you can optimize and increase the performance of your application by distributing tasks in an simple and affordable way.

For web sites with frequent content changes, like news portals, an optimal cache strategy is crucial for serving millions of page views. To just cache every page statically is usually not an option as editors want to see the changes immediately. With the new version of eZ Publish CMS, which is based on Symfony PHP framework, content caching is based on HTTP Cache. This enables much tighter integration with reverse proxies like Varnish and better control of cached pages. Also, Symfony provides ESI capabilities for controlling reverse proxy cache even on block level so invalidating a whole page is not expensive.

What is an etag, exactly? What's all that stuff in the Accept header? And what the heck does a Vary header do anyways?! Web developers use HTTP everyday but most of us don't know how to get the most out of it. This talk goes past memorizing status codes (although we'll see those too) and teaches how to get the most out of every request and response.
