This document provides steps for deploying a Node.js application without getting fired, from initial setup through scaling. It begins with installing Node.js on a VPS or virtual private server. Basic steps include initializing version control with Git, adding logging and error handling, and using Upstart to ensure the app runs at boot and respawns if it crashes. Advanced techniques include using multiple processes, a cache like Varnish, staging environments, and eventually multiple app servers with the database on separate boxes controlled by tools like node-control. The document emphasizes automating deployments and scaling gradually over time.
The why and how of moving to PHP 5.5/5.6Wim Godden
With PHP 5.6 out and many production environments still running 5.2 or 5.3, it's time to paint a clear picture on why everyone should move to 5.5 and 5.6 and how to get code ready for the latest version of PHP. In this talk, we'll look at some handy tools and techniques to ease the migration.
With PHP 5.4 out and many production environments still running 5.2 (or older), it's time to paint a clear picture on why everyone should move to 5.3 and 5.4 and how to get code ready for the latest version of PHP.

The DevOps movement aims to improve communication between developers and operations teams to solve critical issues such as fear of change and risky deployments. But the same way that Agile development would likely fail without continuous integration tools, the DevOps principles need tools to make them real, and provide the automation required to actually be implemented. Most of the so called DevOps tools focus on the operations side, and there should be more than that, the automation must cover the full process, Dev to QA to Ops and be as automated and agile as possible. Tools in each part of the workflow have evolved in their own silos, and with the support of their own target teams. But a true DevOps mentality requires a seamless process from the start of development to the end in production deployments and maintenance, and for a process to be successful there must be tools that take the burden out of humans.
Apache Maven has arguably been the most successful tool for development, project standardization and automation introduced in the last years. On the operations side we have open source tools like Puppet or Chef that are becoming increasingly popular to automate infrastructure maintenance and server provisioning.
In this presentation we will introduce an end-to-end development-to-production process that will take advantage of Maven and Puppet, each of them at their strong points, and open source tools to automate the handover between them, automating continuous build and deployment, continuous delivery, from source code to any number of application servers managed with Puppet, running either in physical hardware or the cloud, handling new continuous integration builds and releases automatically through several stages and environments such as development, QA, and production.

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.

Removing Uninteresting Bytes in Software FuzzingAftab 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.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
