The document discusses refactoring methods to simplify method calls. It describes techniques such as renaming methods for clarity, adjusting parameter numbers, hiding unnecessary information, replacing constructors with factory methods, and improving exception handling in methods. Specific refactoring techniques covered include renaming methods, adding/removing parameters, separating queries from modifiers, and parameterizing methods. The overall goal of these refactoring methods is to make code more readable, reusable and maintainable.

Unit, functional, and integration tests are great first steps towards improving the quality of your python project. Ever wonder if there’s even more you can do? Maybe you've heard of property-based testing, fuzzing, and mutation testing but you're unsure exactly how they can help you. In this talk we’ll cover additional types of tests that can help improve the quality and robustness of your python projects: property-based testing, fuzz testing, stress testing, long term reliability testing, and mutation testing.
We’ll also go beyond just covering what these tests are. For each of the test types above, I’ll give you real world examples from open source software that I maintain that shows you the types of bugs each test type can find. I’ll also show you how you can integrate these tests into your Travis CI and/or Jenkins environment.
A lot of people using PHPunit for testing their source code. While I was observing my team
I recognized most of them are only using the standard ssertions like 'assertEquals()' or
'assertTrue()' and are complaining about how hard it is to test the code even when the tests are written first. This talk is about all the stuff not used on a daily basis. It shows you some nice features of PHPUnit and how to use them for your benefit.

WP_Query, pre_get_posts, and eliminating query_posts()Erick Hitter
At the heart of WordPress is the WP_Query class, used to retrieve practically all content from the database and prepare it for display. In this presentation, I’ll discuss the myriad arguments available with WP_Query, the various properties and methods that are automatically populated, and the advanced queries made possible through filters within the class. I’ll also review the pre_get_posts action, detail how it can be used to modify standard WordPress queries and completely eliminate query_posts(), and explain why you’d want to do so in the first place.
With Extbase - a new framework for extension development introduced in TYPO3 4.3 - you are able to develop with the paradigms of FLOW3 today. During this talk, you get in touch with the features of the framework to understand how it supports your development process to develop clean code cost efficient in less time. Extbase is one cornerstone for a smooth transition to TYPO3 v5, another is reusable business domain knowledge in form of Generic Domain Models available in 4.x and 5.x. The Generic Domain Models will enable you to add a Semantic Web topping.
Actors are one of the most popular concurrency models in nowadays software systems. In this talk, we will present zio-actors – a small strongly typed actor library backed by ZIO. He will explain library design, demonstrate its usage, and point out the differences and similarities with Akka.

1. Include the two above files in the root of your OrderDetailsMaintenance project.
2. Make sure to mark them as "Content" and "Copy Always" or "Copy if newer" in the properties window of those two files.
3. Run the Scaffold-DbContext command to create a context class as well as a class to encapsulate the Orders objects from the associated table in the mdf file. Make sure to include the parameters for -Tables Customers (only worry about the attributes associated with the text boxes, you don't need to worry about any other rows from the table)
4. Once you have ran the command, include an app.config file and add a connection string element. Make sure to copy the connection string from your Context class to your app.config. Then edit your context to grab the connection string from the app.config (ConfigurationManager.ConnectionString["Northwind"].ConnectionString)
5. Code the Find button to Find the customer id and populate the details in the below text boxes.
1. If no order is found, display a message box.
6. Code the exit button
7. Code the Save button to update its attributes and call Update and SaveChanges() on that particular entity.
1. Note: If you close the program, reopen it, and search for the entity you recently updated. You may not see the changes depending on how you setup the mdf file in your project (because it copies a new version to the bin directory each time you run the program). So, if you don't see your changes, don't be alarmed.

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.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

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.

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:
