Spring boot Introduction
Spring boot IntroductionJeevesh Pandey Welcome to presentation on Spring boot which is really great and relatively a new project from Spring.io. Its aim is to simplify creating new spring framework based projects and unify their configurations by applying some conventions. This convention over configuration is already successfully applied in so called modern web based frameworks like Grails, Django, Play framework, Rails etc.
Introduction to Spring Boot
Introduction to Spring BootTrey Howard Spring Boot makes it easier to create Spring-based applications and services. It removes boilerplate configuration and provides opinionated defaults to simplify setup of common Spring and related technologies. Some benefits include embedded servers reducing complexity, autoconfiguration that wires components together, and starter dependencies that add common libraries. Spring Boot helps create production-ready Spring applications with less effort.

JavaCro'14 - Scala and Java EE 7 Development Experiences – Peter Pilgrim
JavaCro'14 - Scala and Java EE 7 Development Experiences – Peter PilgrimHUJAK - Hrvatska udruga Java korisnika / Croatian Java User Association Scala is an alternative JVM language with both object-oriented and functional programming paradigms. Scala development with the Java EE 7 platform is definitely possible and can be a pleasant experience. If you have uncertainty about how Scala can fit around the Java EE 7 platform, then this session aims to illustrate the huge benefit that Scala adoption can bring to the platform. Many other developers are taking advantage and the challenge of the JVM’s capability of being a vessel for multi-language programming. You no longer have to write every single project using Java, even if you like Lambdas experiences. For the developer and engineering terms that feeling a little braver than usual, Scala is attractive as it is strongly typed and lets you set the gauge on how object oriented or how functional you want to be. You will learn how to reuse the annotations and creating Scala plain object safely and concisely. This session will highlight and contrast the experience I had developing Scala solutions with Java EE, and there will be plenty of advice about using the functional programming features against the Java object oriented API.

Sample Project & Code Review (40 minutes):
- Project configuration
- Resource
- Representations
- Views
- Health checks
- Metrics
- Tests
Dropwizard at Yammer
Dropwizard at YammerJamie Furness Yammer has been using Dropwizard since 2011 to power many of its services. It started with 3 services using Dropwizard and related libraries like Jersey and Jackson. By 2014, Yammer had over 30 services using Dropwizard running on over 170 nodes. These services store data in databases like PostgreSQL, Cassandra, and Berkeley DB, with caching done using Memcache. Yammer has built its own deployment service using Dropwizard to deploy services across at least 2 nodes for high availability and zero downtime deployments. Services are monitored using tools like Check MK, Ganglia, load balancers, and Hystrix for visibility into metrics and failures.
Production Ready Web Services with Dropwizard
Production Ready Web Services with Dropwizardsullis This document summarizes a presentation about using Dropwizard to build production-ready web services. It discusses how Dropwizard was used at Gilt Groupe to build microservices like a gift certificate service and fraud service. Dropwizard consists of common Java web service components like Jetty, Jersey, and Jackson configured together. It simplifies building RESTful web services by handling tasks like configuration, metrics, and logging out of the box.
Microservices Architecture
Microservices ArchitectureIzzet Mustafaiev - Microservices architecture breaks applications into small, independent services that focus on specific tasks and communicate over well-defined interfaces. This improves scalability, flexibility and allows for independent development and deployment of services.
- The architecture promotes separating concerns, with each small service handling a single "verb" of the application and teams owning service groups. Services are stateless and communicate asynchronously over lightweight protocols.
- Automating deployment through containerization allows for easy rollout of new versions with zero downtime and elastic scaling of services based on demand. Monitoring provides visibility into technical and business metrics of the distributed system.

DockerCon SF 2015: Enabling Microservices @OrbitzDocker, Inc. The slides from Steve Hoffman and Rick Fast's presentation at DockerCon SF 2015 -
Talk Description:
In this talk we will discuss how we enabled decomposition of one of our 250+ system components into a continously deployed microservice cluster.
This includes building a standardized Docker server composed of various local companion services along side the Docker daemon including: dynamic service discovery via Consul, a log relay to a centralized Elasticsearch cluster, and forwarding/batching of Dropwizard metrics to Graphite.
Building on this we'll cover our Jenkins driven automated pipeline for building Docker images and rolling deployments via Ansible using static placement on existing infrastructure while prototyping dynamic placement using Docker + Apache Mesos.
Patterns of resilience
Patterns of resilienceUwe Friedrichsen In this slide deck, I first describe what resilience is, what it is about, why it is important and how it is different from traditional stability approaches.
After that introductory part the main part is a "small" pattern language which is organized around isolation, the typical starting point of resilient software design. I used quotation marks for "small" as even this subset of a complete resilience pattern language still consists of around 20 patterns.
All the patterns are briefly described and for some of the patterns I added a bit of detail, but as this is a slide deck, the voice track - as usual - is missing. Also this pattern language is still sort of work in progress, i.e., it has not yet settled and some details are still missing. Yet I think (or at least hope), that the slides might contain a few useful insights for you.

Java Insecurity: How to Deal with the Constant Vulnerabilities
Java Insecurity: How to Deal with the Constant VulnerabilitiesLumension Just over a decade ago, the outcry over Microsoft’s security problems reached such a deafening level that it finally got the attention of Bill Gates, who wrote the famous Trustworthy Computing memo. Today, many would say that Microsoft leads the industry in security and vulnerability handling.
Now, it’s Java that’s causing the uproar. But has Oracle learned anything from Microsoft in handling these seemingly ceaseless problems? I’ll start by reviewing the wide-ranging Java security changes Oracle is promising to make. They sound so much like the improvements Microsoft made back with Trustworthy Computing that I’m amazed it hasn’t been done before! We’ll move on to discuss what you can do now to address Java security in your environment.
One of the banes of security with Java is the presence of multiple versions of Java, often on the same computer. Sometimes you really need multiple versions of Java to support applications with version dependencies (crazy, I know). But other times, multiple copies of Java are there “just because.” In this webinar, we’ll talk about the current Java mess and how you can get out of it, including:
Assessment. We’ll discuss ways and tools for cataloging what versions of Java are actually out there on your endpoints.
Identification. We’ll look at methods for identifying which versions are actually required by your users; for instance, I’ll show you how you might use Process Tracking and File Access events in the Windows Security Log to see which Java files are being accessed, by whom, and by which programs.
Disabling. Can you just disable Java? Maybe not for everyone, but what if you could disable it for certain roles within your company that make up 25% – or even 75% – of your workforce? That would be worth it. We’ll explore how you might go about such a measure.
Hardening. We’ll dive into the technical details of hardening Java and reducing your Java attack surface, where possible.
Filtering. Another way to reduce your Java risk is by filtering Java content at your gateway. Again not full coverage control – but what is?
Patching. Then, we’ll delve into the Java patching nightmare. Depending on self-updaters on each endpoint, is could be a recipe for disaster, and I’ll explain why. Basically the only way out of the Java mess is a 3rd party solution that can perform centralized patch management and remediation and that’s where our sponsor, Lumension, will come in.
Server Monitoring (Scaling while bootstrapped)
Server Monitoring (Scaling while bootstrapped)Ajibola Aiyedogbon This document discusses server monitoring strategies for scaling applications. It recommends:
1) Using a load balancer and multiple scalable web and database servers to handle increased traffic loads from hundreds of thousands of users on multi-platform apps.
2) Monitoring key server metrics like CPU usage, bandwidth usage, and application errors to improve stability and catch issues.
3) Tracking logs, client errors, and infrastructure bottlenecks to debug problems and prevent outages like those that led some companies to be "acquired" due to technical failures.

Application Security Workshop 
Application Security Workshop Priyanka Aash The document discusses the science behind runtime application self-protection (RASP) and interactive application security testing (IAST). It describes how RASP works by instrumenting application code to perform dynamic taint analysis, tracking tainted data from inputs and checking for policy violations at sinks like database queries. IAST similarly instruments code but also correlates runtime behavior with attacks to confirm vulnerabilities. The document outlines challenges with taint analysis like under-tainting causing false negatives or over-tainting causing false positives. Both RASP and IAST add overhead, and IAST also has limitations of traditional dynamic application security testing.
JavaSecure
JavaSecureSangbeomKim The document discusses several security issues found in the Java Development Kit (JDK) code through auditing, including integer overflows that could allow denial of service attacks or privilege escalation. It presents an "integer overflow" antipattern found in classes like java.util.zip that failed to properly validate array indices, allowing a crash. The issue was later refactored to add proper validation checks to prevent overflow. The document advocates auditing one's own and third-party Java code to detect similar patterns that could enable vulnerabilities.

DevOpsDays SLC - Platform Engineers are Product Managers.pptxJustin Reock Platform Engineers are Product Managers: 10x Your Developer Experience
Discover how adopting this mindset can transform your platform engineering efforts into a high-impact, developer-centric initiative that empowers your teams and drives organizational success.
Platform engineering has emerged as a critical function that serves as the backbone for engineering teams, providing the tools and capabilities necessary to accelerate delivery. But to truly maximize their impact, platform engineers should embrace a product management mindset. When thinking like product managers, platform engineers better understand their internal customers' needs, prioritize features, and deliver a seamless developer experience that can 10x an engineering team’s productivity.
In this session, Justin Reock, Deputy CTO at DX (getdx.com), will demonstrate that platform engineers are, in fact, product managers for their internal developer customers. By treating the platform as an internally delivered product, and holding it to the same standard and rollout as any product, teams significantly accelerate the successful adoption of developer experience and platform engineering initiatives.
AI-proof your career by Olivier Vroom and David WIlliamson
AI-proof your career by Olivier Vroom and David WIlliamsonUXPA Boston This talk explores the evolving role of AI in UX design and the ongoing debate about whether AI might replace UX professionals. The discussion will explore how AI is shaping workflows, where human skills remain essential, and how designers can adapt. Attendees will gain insights into the ways AI can enhance creativity, streamline processes, and create new challenges for UX professionals.
AI’s influence on UX is growing, from automating research analysis to generating design prototypes. While some believe AI could make most workers (including designers) obsolete, AI can also be seen as an enhancement rather than a replacement. This session, featuring two speakers, will examine both perspectives and provide practical ideas for integrating AI into design workflows, developing AI literacy, and staying adaptable as the field continues to change.
The session will include a relatively long guided Q&A and discussion section, encouraging attendees to philosophize, share reflections, and explore open-ended questions about AI’s long-term impact on the UX profession.

Could Virtual Threads cast away the usage of Kotlin Coroutines - DevoxxUK2025João Esperancinha This is an updated version of the original presentation I did at the LJC in 2024 at the Couchbase offices. This version, tailored for DevoxxUK 2025, explores all of what the original one did, with some extras. How do Virtual Threads can potentially affect the development of resilient services? If you are implementing services in the JVM, odds are that you are using the Spring Framework. As the development of possibilities for the JVM continues, Spring is constantly evolving with it. This presentation was created to spark that discussion and makes us reflect about out available options so that we can do our best to make the best decisions going forward. As an extra, this presentation talks about connecting to databases with JPA or JDBC, what exactly plays in when working with Java Virtual Threads and where they are still limited, what happens with reactive services when using WebFlux alone or in combination with Java Virtual Threads and finally a quick run through Thread Pinning and why it might be irrelevant for the JDK24.
