Monitoring a billion kilometers of monthly ride sharing at BlaBlaCar - Zabbix...Jean Baptiste Favre
How BlaBlaCar designed and operates a Zabbix based monitoring platform, optimizing Zabbix configuration, developping & using python-protobix & jmx-zabbix for more scalability
With the widespread adoption of Git, and the rollout of Git-based development workflows, large organizations must be able to scale their source code management system with their needs. In this talk we will provide practical advice to overcome the challenges in scaling Git.
This talk explains the installation and configuration of a Linux high availability network gateway using keepalived and conntrackd. This results in an active-standby topology. Necessary scripts are implemented to keep the configuration in sync of both gateways. Keepalived is used to manage active-standby negotiation. Conntrackd is used to synchronize network states across the gateways.
Suricata: A Decade Under the Influence (of packet sniffing)Jason Williams
Having just celebrated it's 10th birthday, Suricata has learned a lot about monitoring network traffic during the past decade. Suricata today is more than IDS/IPS— it is also a metadata creating, lua scripting, multi threaded, json logging, rule alerting, network security monitoring beast. Development for Suricata is funded by the non-profit Open Information Security Foundation which, along with feedback and support from the community, has made Suricata what it is today. In this talk we will discuss various aspects of modern Suricata, such as deployment, alerting, rule writing, compilation, protocols, lua, and more. Join us for a look into where Suricata has been, what it does today, and where it's going to go in the future.

One thing that most programmers do not take the time to understand is the servers that their application lives on. Most know a smattering of Apache configs, PHP configs, and basic information about the OS. This talk will deal with looking at tools that can help you quickly set up a server and how it can help you be a better developer. We'll look at tools like Puppet for server management, OSSEC for log management, different command line tools, and Nagios/Monit for system monitoring.
Everyone knows installing PHP on IBM i is easy. Just download the save file and run the RSTLICPGM command. But not everyone knows what that RSTLICPGM does. What is it putting on the machine? Where is it putting it? How does it all work together? In this session, we'll take a look at the IFS directories added by the Zend Server installer, to see what's in them. We'll see where PHP and PHP extensions, Apache and FastCGI configurations, log files, and more are kept. We'll also talk about how these new file objects interact with existing prerequisite software on the IBM i to present dynamic pages to the web. This session is for PHP developers and administrators interested in learning how PHP fits in with the unique operating environment of IBM i.
The presentation is the result of my investigating if there is an open source development framework that can manage complex robotic systems. If so,should it be recommended to be used in advanced high school/undergraduate levels.
Linux Server Deep Dives (DrupalCon Amsterdam)Amin Astaneh
Over the past few years the Linux kernel has gained features that allow us to learn more about what's really happening on our servers and the applications that run on them.
This talk will explore how these new features, particularly perf_events and ebpf, enable us to answer questions about what a Drupal site is doing in real time beyond what the standard logs, server performance tools, and even strace will reveal. Attendees will be provided a brief introduction to example uses of these tools to diagnose performance problems.
This talk is intended for attendees that are familiar with Linux, the command line, and have used host observability tools in the past (top, netstat, etc).

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).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige 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:

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.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
