Spring Day | Spring and Scala | Eberhard WolffJAX London
2011-10-31 | 09:45 AM - 10:30 AM
Spring is widely used in the Java world - but does it make any sense to combine it with Scala? This talk gives an answer and shows how and why Spring is useful in the Scala world. All areas of Spring such as Dependency Injection, Aspect-Oriented Programming and the Portable Service Abstraction as well as Spring MVC are covered.
The document provides a biography and background information on Daniel N. Egan, including his roles as a Microsoft Regional Director, Microsoft MVP for ASP.Net, author, and speaker. It then outlines the topics to be covered in the presentation, including object relational mappers, language enhancements in C# and VB.Net, LINQ goals, fundamentals and usage.
Default methods and static methods allow interfaces to define new methods without breaking existing implementations. The lambda expressions feature introduces functional programming to Java through functional interfaces like Consumer and Function. The streams API provides a functional-style way to process and analyze collections through parallelization, optional return values, and collectors.
Functional Programming With Lambdas and Streams in JDK8IndicThreads
The significant new language feature in Java SE 8 is the introduction of Lambda expressions, a way of defining and using anonymous functions. On its own this provides a great way to simplify situations where we would typically use an inner class today. However, Java SE 8 also introduces a range of new classes in the standard libraries that are designed specifically to take advantage of Lambdas. These are primarily included in two new packages: java.util.stream and java.util.function.
After a brief discussion of the syntax and use of Lambda expressions this session will focus on how to use Streams to greatly simplify the way bulk and aggregate operations are handled in Java. We will look at examples of how a more functional approach can be taken in Java using sources, intermediate operations and terminators. We will also discuss how this can lead to improvements in performance for many operations through the lazy evaluation of Streams and how code can easily be made parallel by changing the way the Stream is created.

Using Stratego/XT for generation of software connectors.Michal Malohlava
This document discusses using Stratego/XT to generate software connectors. It proposes designing a domain specific language called ElLang-J, which is a mixture of ElLang and Java, to define templates for connector element implementations. The templates would be evaluated using Stratego/XT to generate Java source code for the connectors. The solution involves a Java part to prepare low-level connector configuration and a Stratego part to generate code from the templates and configuration. Evaluation finds advantages in the extensible templates but also disadvantages in Stratego/XT being C-based while the rest of the generator is Java.

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:
Why You Should Replace Windows 11 with Nitrux Linux 3.5.0 for enhanced perfor...SOFTTECHHUB
The choice of an operating system plays a pivotal role in shaping our computing experience. For decades, Microsoft's Windows has dominated the market, offering a familiar and widely adopted platform for personal and professional use. However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.
Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
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.

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.
