2 gefällt mir•3,921 views

La performance d'une application. Tout le monde en parle. Mais êtes-vous outillés pour suivre son évolution entre chacune de vos itérations de développements ? Ou même avant chaque mise en prod. ? Lors de cette conférence, je vous propose de découvrir Blackfire (ex-SensioLabsProfiler), un nouvel outil qui simplifie drastiquement la collecte et la compréhension de profils de performance PHP. Après avoir fait l'état de l'art sur le sujet (xhprof, xDebug), nous ferons un tour d'horizon des principales innovations de l'outil : expérience utilisateur simplifié, agrégation, visualisation de graphes, mise en avant des bottlenecks, comparaison de profils, etc. Voilà le moyen de mettre des nombres réels en face de vos intuitions, avec pour mot d'ordre : « getting and staying performant ».

For new and veteran PHP programmers alike, it’s often difficult to find the right place to ask questions and find the best answers and solutions to programming challenges. This month, Ben Ramsey takes us on a journey through the PHP Community to discover the websites the experts use to get PHP news and information and the places they go to ask for help (because even experts need help). He’ll wrap up the talk with a brief who’s who in the PHP Community, introducing you to some of the core developers and familiar faces around the community.

The Sodium crypto library (libsodium) is a modern, easy-to-use software library for encryption, decryption, signatures, password hashing and more. Sodium has been added to PHP 7.2 as core extension. In this talk we will show how to use Sodium in PHP projects to solve common problems, like how to store the users’ password, how to encrypt/decrypt sensitive information, how to authenticate user’s data, etc. We’ll also present some of the advanced features of libsodium like authenticated encryption, anonymous public-key encryption, and elliptic curve cryptography.

Vous avez beau avoir modernisé vos applications, les avoir rendu stateless, 12factor-compliant, etc., si vous n'avez pas l'infrastructure pour les déployer proprement et les gérer, votre bénéfice final sera fortement amoindri. Cette conférence a pour but de vous faire ressortir avec une définition et une vision claires des principaux concepts qui caractérisent une infrastructure moderne. Nous y parlerons Configuration Management, infrastructure immuable, infra-as-Code, orchestration, self-healing, systèmes distribués, applications Cloud Native, Serverless ... et ce n'est qu'un avant goût !

BizTalk Architects have always taken themselves a bit too seriously and have been able to dictate rules for integration based on things that is important to no one but them. Only the BizTalk architect really care about port names and making the BizTalk environment look pretty. We are at a time in history were “integration is hard” is becoming less and less of an excuse for such behavior. Both technology and people have become smarter and integration has shifted to a more function based focus. Make it work is more important than make is pretty and reusable. I will be presenting a solution to all these problems.

Doctrine 2 is an object relational mapper (ORM) for PHP 5.3+ that sits on top of a powerful database abstraction layer (DBAL). One of its key features is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL), inspired by Hibernates HQL. This provides developers with a powerful alternative to SQL that maintains flexibility without requiring unnecessary code duplication.

PHP has been around for many years and has been used any number of ways and in projects large and small, one of its little known and seldom used functions is in that of raw audio generation and output. In a show of its extreme versatility for the awesomeness that is PHP, we are going to hear what php code can sound like helping push one of the little known and often rarely used functions to create music from elegant symphonies to some of the latest tunes. We will also hear what code from some of the more well known platforms sounds like.

With more memory available, system performance of three Dell devices increased, which can translate to a better user experience Conclusion When your system has plenty of RAM to meet your needs, you can efficiently access the applications and data you need to finish projects and to-do lists without sacrificing time and focus. Our test results show that with more memory available, three Dell PCs delivered better performance and took less time to complete the Procyon Office Productivity benchmark. These advantages translate to users being able to complete workflows more quickly and multitask more easily. Whether you need the mobility of the Latitude 5440, the creative capabilities of the Precision 3470, or the high performance of the OptiPlex Tower Plus 7010, configuring your system with more RAM can help keep processes running smoothly, enabling you to do more without compromising performance.
