Symfony 3.0 vient tout juste de sortir. Évidement, la compatibilité PHP7 est au rendez-vous. Et comme pour PHP7, tout a été fait pour que la migration vers ces toutes dernières technologies se fasse le plus simplement possible pour vous. Avec Symfony 3.0, le framework innove en continuité, sans vous obliger à réécrire toute votre application! Comment est-ce possible? Dans cette session, vous découvrirez comment la promesse rétro-compatibilité assure des migrations facilitées. Je vous présenterai également la nouvelle politique de dépréciation commencée avec Symfony 2.7. Ce sont les deux pierres angulaires qui permettent à Symfony de faire le grand écart : motoriser de nombreuses applications stables en production, sans sacrifier l'innovation au sein du framework.

Symfony Debug & VarDumper

nicolas.grekas

Il n'y a que des bugs faciles à résoudre... quand on a de quoi les cerner ! Le développeur PHP dispose de toute une panoplie d'outils pour tracker les situations les plus rocambolesques. Depuis ses débuts, Symfony n'a eu de cesse d'améliorer l'expérience du développeur en proposant des solutions d'accompagnement robustes et génériques. Les connaissez-vous suffisament ? Lors de cette présentation, je vous donnerai les clefs des mécanismes de debugging présents dans Symfony : VarDumper, Web Debug Toolbar, logs, gestionnaire d'erreur fatales et d'exceptions, etc.

The fall of the BizTalk Architect – From something abstract to something useful

BizTalk360

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: Enterprise Persistence Layer for PHP

Jonathan Wage

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.

PHPConf.Asia - The Sound of PHP

Steven Cooper

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.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs

Alex Pruden

This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Removing Uninteresting Bytes in Software Fuzzing

Aftab Hussain

Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process. In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds. - These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan Dix

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024 https://alandix.com/academic/papers/synergy2024-epistemic/ As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf

Paige Cruz

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack. While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack. I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
