Keep hearing about Plack and PSGI, and not really sure what they're for, and why they're popular? Maybe you're using Plack at work, and you're still copying-and-pasting `builder` lines in to your code without really knowing what's going on? What's the relationship between Plack, PSGI, and CGI? Plack from first principles works up from how CGI works, the evolution that PSGI represents, and how Plack provides a user-friendly layer on top of that.

Most applications written in Ruby are great, but also exists evil code applying WOP techniques. There are many workarounds in several programming languages, but in Ruby, when it happens, the proportion is bigger. It's very easy to write Ruby code with collateral damage.
You will see a collection of bad Ruby codes, with a description of how these codes affected negatively their applications and the solutions to fix and avoid them. Long classes, coupling, misapplication of OO, illegible code, tangled flows, naming issues and other things you can ever imagine are examples what you'll get.
Diving into HHVM Extensions (PHPNW Conference 2015)James Titcumb
HHVM is currently gaining popularity at quite a pace, and it's a pretty exciting time for PHP runtimes. Have you ever wondered what is going on beneath this slick and super-speedy engine? I wondered that myself, so I dived into the internals of HHVM, discovering a treasure trove of awesome stuff. In this talk, I'll show you how HHVM itself works with a guided tour of the codebase, demonstrating how it all pieces together. I'll also show you a couple of ways to write your own incredible HHVM extension. You don't need to know C++ to understand this talk - just PHP language knowledge is enough.
Tobias Nyholm "Deep dive into Symfony 4 internals"Fwdays
Symfony is a request and response framework. But what about all that magic that happens around your code? How does security work? Why isn’t autowring slowing things down? And how is it that symfony components can be so decoupled but still play so well together?
I will show you the symfony internals
This talk will go over the architecture of Symfony. We will follow the request and the response paths throw the framework. We will do some stops at the components that are more awesome than others.
This talk is perfect for those who's worked with Symfony or Laravel before. But if you've never touched a framework before, don't worry. You will still learn a lot from this talk.

Towards the end of 2015 Rareloop launched their WordPress starter theme Lumberjack, which built on open source tools such as Bedrock and Timber. We wanted to move Lumberjack forward inline with everything we have learnt over the years of using it - which meant completely re-writing it from the ground up. The new Lumberjack is now stable and ready for use!
This talk is aimed at anyone involved in working with WordPress, regardless of how technical you are. The beauty of Lumberjack is that you can use as much or as little as you like, so whether you’re new to web development or a seasoned software engineer there will be something here for you.

Effective Java with Groovy - How Language Influences Adoption of Good PracticesNaresha K
Slides from my APACHECON@HOME 2020 talk - "Effective Java with Groovy - How Language Influences Adoption of Good Practices".
'Effective Java' presents the most effective ways of using language. However, the adoption of these practices among Java developers is less than satisfactory. In my observation, the effort required to implement them can be a barrier to the adoption of these practices. Since Groovy runs on JVM, most of the suggestions from Effective Java are equally relevant for Groovy developers. Groovy provides out of the box constructs for many of the recommended practices which can boost developer productivity. In this talk, I walk you through code examples that follow these good practices, highlighting the Groovy way of implementing the 'Effective Java' suggestions. As a participant, you walk away, appreciating the simplicity with which Groovy empowers the developers. The talk also provides food for thought - how a language can influence its users to adopt good practices. Java users learn the techniques a language can use to reduce the friction to adoption of good practices, instead of coming up with a prescription on how to implement good practices. Developers familiar with Groovy understand the reason behind the design of their favourite language features.
The $path to knowledge: What little it take to unit-test Perl.Workhorse Computing
Metadata-driven lazyness, Perl, and Jenkins provide a nice mix for automated testing. With Perl the only thing required to start testing is a files path, from there the possibilities are endless. Using Symbol's qualify_to_ref makes it easy to validate @EXPORT & @EXPORT_OK, knowing the path makes it easy to use "perl -wc" to get diagnostics.
The beautiful thing is all of it can be lazy... er, "automated". And repeatable. And simple.

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.
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.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

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!
