This document discusses the differences between domain models and relational database models. Specifically, it notes that in a domain model, a member entity can have a member status anywhere, but in a relational database, the member status is only available if joined from another table. It recommends using inversion of control and interfaces to decouple the view, domain, and data access layers so that domain entities never return null values for member status.

Filesystem Abstraction with Flysystem
This document discusses filesystem abstraction using Flysystem. It begins by explaining how filesystem abstraction bridges the gap between different filesystem implementations so the storage engine becomes an implementation detail. It then provides an overview of common filesystem concepts and operations. Finally, it introduces Flysystem as an abstraction layer that provides a unified API for working with various filesystems like local, S3, FTP, enabling easier code reuse and testing.
Ex[1].3 php db connectivity
The document describes how to connect a PHP script to a MySQL database and perform CRUD (create, read, update, delete) operations. It explains how to connect to the database, create tables, insert, update, delete and select data. Code examples are provided to create PHP files that connect to the database and perform each operation through a web form interface. The output displays the results of running the PHP scripts to interact with the database.
TurboGears2 Pluggable Applications
This document discusses using pluggable applications with TurboGears2. It provides an overview of TurboGears2 features like object dispatch, declarative models, and XML template engines. It then demonstrates how to quickly start an application and explore options to add photo galleries, blogs, and wiki pages by plugging in additional applications and customizing templates and models.
Di and Dagger
The document discusses dependency injection (DI) and how Dagger can be used to implement DI. It begins with an example Android application that manages a lock dashboard. The code to create dependencies is complex and error-prone. Dagger addresses this by generating code to manage object creation and injection. It works by analyzing how objects relate via a directed acyclic graph (DAG) of their dependencies. Modules provide object instances to the graph, and components inject them where needed. This allows clean, testable separation of concerns and simplifies object creation.

Service discovery and configuration provisioning
Slides from our talk "Service discovery and configuration provisioning" presented by Mariusz Gil at PHP Benelux 2016
Apache Zookeeper or Consul are almost completely unknown in the PHP world, although its use solves a lot of typical problems. In a nutshell, they are a central services of provisioning configuration information, distributed synchronization and coordination of servers/processes. It simplifies the processes of application configuration management, so it is possible to change its settings and operation in real time (eg. feature flagging). During the presentation the typical cases of use of Zookeeper/Consul in PHP applications will be presented, both strictly web and workers running from the CLI.

Securing your Kubernetes cluster_ a step-by-step guide to success !
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.

Removing Uninteresting Bytes in Software Fuzzing
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.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
