Quarkus - a next-generation Kubernetes Native Java frameworkSVDevOps
For years, the client-server architecture has been the de-facto standard to build applications. But a major shift happened. The one model rules them all age is over. A new range of applications and architectures has emerged and impacts how code is written and how applications are deployed and executed. HTTP microservices, reactive applications, message-driven microservices, and serverless are now central players in modern systems.
Quarkus has been designed with this new world in mind and provides first-class support for these different paradigms. Developers using the Red Hat build of Quarkus can now choose between deploying natively compiled code or JVM-based code depending on an application’s needs. Natively compiled Quarkus applications are extremely fast and memory-efficient, making Quarkus a great choice for serverless and high-density cloud deployments.

In summary, this informative session will provide you valuable insights into the benefits of using Quarkus while also getting real world performance and development time numbers from Vodafone, information which can and should influence your next decisions on what Server Side Java technology to choose!
There are quite many talks about Quarkus, explaining basic development mechanics and advertising extremely small memory footprint and slim deployment artifacts. However in all those talks audience has just to "believe", almost nobody explains, how does Quarkus achieve it, what tools and approaches work under the hood. I'm going to provide a balanced explanation, giving knowledge of how it works behind the scenes, but not going into long complex theoretical stories, which make people sleep during the talk.
Quarkus offers a great development experience. In this session, I’ll introduce you to the power of Quarkus Live Coding and tools that are useful to developers for debugging, deploying, and testing Quarkus applications.

Running Kafka as a Native Binary Using GraalVM with Ozan GünalpHostedbyConfluent
"During development and automated tests, it is common to create Kafka clusters from scratch and run workloads against those short-lived clusters. Starting a Kafka broker typically takes several seconds, and those seconds add up to precious time and resources.
How about spinning up a Kafka broker in less than 0.2 seconds with less memory overhead? In this session, we will talk about kafka-native, which leverages GraalVM native image for compiling Kafka broker to native executable using Quarkus framework. After going through some implementation details, we will focus on how it can be used in a Docker container with Testcontainers to speed up integration testing of Kafka applications. We will finally discuss some current caveats and future opportunities of a native-compiled Kafka for cloud-native production clusters."

Simple tweaks to get the most out of your jvmJamie Coleman
Many developers don’t think about the JVM level when creating applications. It is something that just simply works. Now more applications are becoming cloud-native and we have JVM’s running in every microservice container, each performance gain can have massive benefits when scaled up. Some tweaks are very easy to implement and can have huge impacts on start-up time and performance of your applications. This talk will go through all the different JVM options and give you some easy and simple advice on how to get the most out of your JVM to save not only money but also energy on the cloud.

Performance of Microservice frameworks on different JVMsMaarten Smeets
A lot is happening in world of JVMs lately. Oracle changed its support policy roadmap for the Oracle JDK. GraalVM has been open sourced. AdoptOpenJDK provides binaries and is supported by (among others) Azul Systems, IBM and Microsoft. Large software vendors provide their own supported OpenJDK distributions such as Amazon (Coretto), RedHat and SAP. Next to OpenJDK there are also different JVM implementations such as Eclipse OpenJ9, Azul Systems Zing and GraalVM (which allows creation of native images). Other variables include different versions of the JDK used and whether you are running the JDK directly on the OS or within a container. Next to that, JVMs support different garbage collection algorithms which influence your application behavior. There are many options for running your Java application and choosing the right ones matters! Performance is often an important factor to take into consideration when choosing your JVM. How do the different JVMs compare with respect to performance when running different Microservice implementations? Does a specific framework provide best performance on a specific JVM implementation? I've performed elaborate measures of (among other things) start-up times, response times, CPU usage, memory usage, garbage collection behavior for these different JVMs with several different frameworks such as Reactive Spring Boot, regular Spring Boot, MicroProfile, Quarkus, Vert.x, Akka. During this presentation I will describe the test setup used and will show you some remarkable differences between the different JVM implementations and Microservice frameworks. Also differences between running a JAR or a native image are shown and the effects of running inside a container. This will help choosing the JVM with the right characteristics for your specific use-case!
Imagine a Java application that can start up in milliseconds, without compromising on throughput, memory, development-production parity or Java language features. Sounds out of this world, right? Well, through the use of technologies like CRIU support in Eclipse OpenJ9 and Liberty’s InstantOn, we’ve taken one giant leap forwards for innovation within Java, offering exactly this! Join this session to learn more about these innovations and how you could utilise OSS technologies to deliver highly scalable and performant applications that are optimized for today’s cloud-native environments.
Java in 2019 was predicted to be business as usual by many. We have seen new Java releases coming out as planned, AdoptOpenJDK became the main trustful source of binaries and Oracle fighting for the trademark again by preventing the use of javax as namespace. Everything looks like it would be a silent year for Java. But one thing seems obvious. Java's popularity is not gaining any more traction. New language features keep it up to date but people are getting more selective when it comes to implementation choices. Especially in the age of containers and cloud infrastructures. This talk walks you through the why and how of Java in containers. We will talk about image size and development and deployment processes.
Micronaut: A new way to build microservicesLuram Archanjo
Over the years microservices architecture has been widely adopted in conjunction with Spring Boot. But recently, we are witnessing the rise of microframeworks such as Micronaut, which has innovated the way we build microservices by providing low memory consumption, fast startup, non-blocking, and other important features that I will demonstrate and conceptualize in this talk.

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.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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.

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.
LF Energy Webinar: Electrical Grid Modelling and Simulation Through PowSyBl -...DanBrown980551
Do you want to learn how to model and simulate an electrical network from scratch in under an hour?
Then welcome to this PowSyBl workshop, hosted by Rte, the French Transmission System Operator (TSO)!
During the webinar, you will discover the PowSyBl ecosystem as well as handle and study an electrical network through an interactive Python notebook.
PowSyBl is an open source project hosted by LF Energy, which offers a comprehensive set of features for electrical grid modelling and simulation. Among other advanced features, PowSyBl provides:
- A fully editable and extendable library for grid component modelling;
- Visualization tools to display your network;
- Grid simulation tools, such as power flows, security analyses (with or without remedial actions) and sensitivity analyses;
The framework is mostly written in Java, with a Python binding so that Python developers can access PowSyBl functionalities as well.
What you will learn during the webinar:
- For beginners: discover PowSyBl's functionalities through a quick general presentation and the notebook, without needing any expert coding skills;
- For advanced developers: master the skills to efficiently apply PowSyBl functionalities to your real-world scenarios.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Smart TV Buyer Insights Survey 2024 by 91mobiles.pdf91mobiles
91mobiles recently conducted a Smart TV Buyer Insights Survey in which we asked over 3,000 respondents about the TV they own, aspects they look at on a new TV, and their TV buying preferences.
4. Container First
Minimal footprint Java apps optimal for running in containers
Cloud Native
Embraces 12 Factor architecture in cloud environments like Kubernetes
Microservice First
Brings lightning fast startup time and code turn around Java
Why supersonic and subatomic java ?
8. DEVELOPER JOY
• Easy to start with
• Live reload with dev mode
• Java or Kotlin
• Maven or Gradle
• Runners for Junit 4 and 5
• Isolation from GraalVM CLI/API
12. TRADITIONAL APP SERVER
• JIT Compilation
• Runtime approach : hundreds of classes run only during the boot
• Later unused and occupy memory
• Ex: XML parsers, annotation lookups, management model, etc.
QUARKUS SERVER
• AoT Compilation
• Build time approach
• As much work as possible done at build time
• Build time augmentation using extensions
• Output: recorded wiring bytecode
VS
13. QUARKUS EXTENSIONS
Philosophy:
• Transform your entire app including the libraries it uses,
into an native image optimized for GraalVM
• Closed world assumption
3 Phases of Bootstrap:
• Augmentation: Produce recorded bytecode @Record(STATIC_INIT) or
@Record(RUNTIME_INIT)
• Static Init : Executed at build time in a static method on main class
• Runtime init : Executed at runtime
14. Two distinct things:
1. Graal compiler (AoT or JIT)
2. GraalVM – the polyglot VM
Supports Linux and macOS,
not windows yet
16. AoT compilation
• Static analysis
• Statically linked executable (app classes, jdk classes)
• Closed world assumption
• Dead code elimination
Enable:
• Fast process start
• Less memory
• Small size on disk
17. LIMITATIONS
« With great powers comes great cost »
• Dynamic class loading: unsupported
• JMX, JVMTI: unsupported
• Agents (jrebel, byteman, profilers): unsupported
• Java debugger: unsupported, but Native debugger (GDB) supported
• Reflection, dynamic proxies: limited
Toolkit: maven/gradle build tool, create/scaffold new project, dev mode, jar packaging, build native image
Framework: à la spring boot: web server, configuration, injections, testing, based on standards, extensions
- Augmentation: produit des @Recorded bytecode
Static init: If bytecode is recorded with @Record(STATIC_INIT) then it will be executed from a static init method on the main class.
Runtime Init: If bytecode is recorded with @Record(RUNTIME_INIT) then it is executed from the application’s main method. This code will be run on native executable boot. In general as little code as possible should be executed in this phase, and should be restricted to code that needs to open ports etc.
Custom extensions
- Universal VM for running applications written in JavaScript, Python, Ruby, R, JVM-based languages like Java, Scala, Groovy, Kotlin, Clojure, and LLVM-based languages such as C and C++.
- Removes the isolation between programming languages and enables interoperability in a shared runtime.
- run either standalone or in the context of OpenJDK, Node.js or Oracle Database.
- The resulting native binary contains the whole program in machine code form for its immediate execution.
Improve the performance of JVM-based languages to match the performance of native languages.
Reduce the startup time of JVM-based applications by compiling them AOT
Enable GraalVM integration into the Oracle Database, OpenJDK, Node.js, Android/iOS, and to support similar custom embeddings.
Allow freeform mixing of code from any programming language in a single program, billed as "polyglot applications".[7][9]
Dynamic class loading: deploying jars, wars, etc. at runtime impossible
Reflection: requires registration via native-image CLI/API or @RegisterForReflection in Quarkus
