I will share a study based on incoming traffic to our darknet which is just monitoring and discarding packets. So basically there is no user traffic, but still we are observing many incoming traffic. Mostly those are scanning but also we found many interesting activities.
The same might be happing to every Internet facing host, and it's important to understand the current situation of the Internet.

200, 404, 302. Is it a lock combination? A phone number? No, they're HTTP status codes! As we develop Web applications, we encounter these status codes and others, and often we make decisions about which ones to return without giving much thought to their meaning or context. It's time to take a deeper look at HTTP. Knowing the methods, headers, and status codes, what they mean, and how to use them can help you develop richer Internet applications. Join Ben Ramsey as he takes you on a journey through RFC 2616 to discover some of the gems of HTTP.
Speedy App: Frontend Performance ConsiderationsPierre Spring
Execution time in the backend is not all there is to the speed of a web application. In this talk, we'll look at the basic enhancements we can make to get an applications that truly feels snappy!
Presentation given at the International PHP conference in Mainz, October 2012, dealing with a bit of history about the HTTP protocol, SPDY and the future (HTTP/2.0).
In this presentation, I show the audience how to implement HTTP caching best practices in a non-intrusive way in PHP Symfony 4 code base.
This presentation focuses on topics like:
- Caching using cache-control headers
- Cache variations using the Vary header
- Conditional requests using headers like ETag & If-None-Match
- ESI discovery & parsing using headers like Surrogate-Capability & Surrogate-Control
- Caching stateful content using JSON Web Token Validation in Varnish

HTTP/2 (or “H2” as the cool kids call it) has been ratified for months, and browsers already support or have committed to supporting the protocol. Everything we hear tells us that the new version of HTTP will provide significant performance benefits while requiring little to no change to our applications—all the problems with HTTP/1.x have seemingly been addressed; we no longer need the “hacks” that enabled us to circumvent them; and the Internet is about to be a happy place at last.
But maybe we should put the pom-poms down for a minute. Deploying HTTP/2 may not be as easy as it seems since the protocol brings with it new complications and issues. Likewise, the new features the spec introduces may not work as seamlessly as we hope. Hooman Beheshti examines HTTP/2’s core features and how they relate to real-world conditions, discussing the positives, negatives, new caveats, and practical considerations for deploying HTTP/2.
Topics include:
The single-connection model and the impact of degraded network conditions on HTTP/2 versus HTTP/1
How server push interacts (or doesn’t) with modern browser caches
What HTTP/2’s flow control mechanism means for server-to-client communication
New considerations for deploying HPACK compression
Difficulties in troubleshooting HTTP/2 communications, new tools, and new ways to use old tools
Why is Performance important?
Applications in general
Web applicaitons
What can we as devs do?
Tips: How to optimize
Web applications, Silverlight, Backend, …
Regression
How to maintain performance over time
How to get faster over time
Discussion: What tips do you have in your toolbox?
HTTP 2.0 is supposed to be the next big thing for the web, after the overwhelming success of HTTP 1.1.
A dive into the HTTP 2.0 protocol, what is the status of its specification, what features does it offer over HTTP 1.1, and how websites can benefit (in speed and money) from it.
An exploration of what does it take to write HTTP 2.0 applications in the Java platform, what plans there are to support it in JDK 9 and which Servlet Containers are already offering HTTP 2.0 support.
This presentation is based on the original one from the author of the book ( 'Steve Souders' ), it's about his book titled 'High Performance Websites''

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.

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!

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan 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.

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:
