Spark SQL: Another 16x Faster After Tungsten: Spark Summit East talk by Brad ...Spark Summit
Apache Spark 2.1.0 boosted the performance of Apache Spark SQL due to Project Tungsten software improvements. Another 16x times faster has been achieved by using Oracle’s innovations for Apache Spark SQL. This 16x improvement is made possible by using Oracle’s Software in Silicon accelerator offload technologies.
Apache Spark SQL In-memory performance is becoming more important due to many factors. Users are now performing more advanced SQL processing on multi-terabyte workloads. In addition on-prem and cloud servers are getting larger physical memory to enable storing these huge workloads be stored in memory. In this talk we will look at using Spark SQL in feature creation, feature generation within pipelines for Spark ML.
This presentation will explore workloads at scale and with complex interactions. We also provide best practices and tuning suggestion to support these kinds of workloads on real applications in cloud deployments. In addition ideas for next generation Tungsten project will also be discussed.
Was jeder Java-Entwickler über Strings wissen sollteberndmueller
Strings sind wahrscheinlich der am meisten verwendete Datentyp in jeder
Java-Anwendung. Es ist daher nicht überraschend, dass JDK-Ingenieure
versuchen, Strings möglichst gut zu optimieren oder Bücher über
Performanz-Tuning und Testen dem Thema Strings ganze Kapitel widmen.
Jeder Entwickler sollte daher wissen, was Strings sind und wie sie
sinnvoll und effizient eingesetzt werden können.
Dieser Vortrag stellt JDK-Klassen vor, die mit und auf Strings
arbeiten, sowohl auf der API- aber auch auf der
Implementierungsebene. Wir beleuchten internte Strings und die für sie
verwendeten Speicherbereiche, sowie die noch recht unbekannte
"String-Deduplication"-Option des G1-Garbage-Collectors.
Mit Java 9 ändert sich die interne Repräsentation von Strings.
Wir skizzieren diese Änderungen, die nach außen unsichtbar
bleiben.

The future of Java is insight with Java 9 around the corner. Last year's discussions around the removal from sun.misc.Unsafe and the eventually presented compromise is history. Time to start looking forward to some details from what's coming, especially in terms of the Unsafe API replacement.
Pitfalls of migrating projects to JDK 9Pavel Bucek
Java 9 brings revolutionary changes. There is a big difference between their adoption and adoption of similarly revolutionary features of Java 8: lambdas and streams could gradually be included in a project, but Jigsaw requires some significant changes to the existing code. Jersey and Tyrus are popular open source libraries of considerable size and cherish backward compatibility. This session presents lessons learned during a migration to Java 9 and adoption of Jigsaw features. The nature of the projects and their features—such as resource injection or scanning and using user-provided (thus unknown, in standard dependency view) classes—make the migration particularly interesting and informative for future Java 9 adopters.
Technische Schulden in Architekturen erkennen und beseitigenCarola Lilienthal
Beim Entwurf der Softwarearchitektur zu Beginn eines Projekts bringen die Architekten i.d.R. all ihre Erfahrung und ihr Knowhow ein und stellen eine Architektur-Blaupause für die Entwicklung bereit. Aber während der Implementierung weichen die Entwickler ungewollt mehr und mehr von diesen Vorgaben ab: Einerseits macht der Projektdruck Abweichungen notwendig, andererseits entstehen die Abweichungen ungewollt und unbemerkt. Die Architektur des Systems erodiert und es werden Schritt für Schritt technische Schulden aufgebaut. Wartung und Erweiterung der Software werden immer teurer bis zu dem Punkt, an dem jede Änderung zu einer schmerzhaften Anstrengung wird.
In diesem Vortrag berichte ich von meinen Erfahrungen der letzten zehn Jahre mit der Analyse von Softwarearchitekturen in Java (60 Systeme), C# (10 Systeme), C++(6 Systeme): Die Zuhörer wissen nach meinem Vortrag, welche Fehler sie in ihren Softwareprojekten bei der Umsetzung der Architektur nicht machen sollten, welche Prinzipien Sie einhalten sollen, um technische Schulden nicht entstehen zu lassen, welche Tools helfen, technische Schulden aufzuspüren, und wie technische Schulden abgebaut werden können.

Ein Prozess lernt laufen – LEGO® MINDSTORMS® Steuerung mit BPMNOliver Hock
Betriebliche Abläufe gehören zum Geschäftsalltag wie LEGO zur Kindheit. Dennoch mangelt es in vielen Unternehmen an der Transparenz und Wiederverwendbarkeit dieser Abläufe. Mit der „Business Process Modeling Notation“ (BPMN) lässt sich dieses Manko beseitigen und Fachabteilungen und Technik wachsen zusammen. Zusätzlich wird die Geschäftswelt ortsübergreifend visualisiert. Als Ergebnis entstehen Diagramme, die als Dokumentation für das Business dienen und Automationsgrundlage der IT sind.
Im Gegensatz hierzu steht das praktische Lernen mit LEGO-Mindstorms. Ein kleiner Roboter wird in mannigfaltigen Ausprägungen zusammengebaut, mit einer Java-API gefüttert und über externe Software gesteuert. Seriell und parallel geschaltete Einzelschritte erwecken unseren beweglichen Freund zum Leben.
In diesem Vortrag wird der Bogen zwischen Prozessen und Robotern gespannt. Bewegungsabläufe werden mit BPMN2 definiert und mittels einer „Business Process Engine“ automatisiert. Es wird die Herangehensweise der Modellierung inklusive BPMN-Basics, Strukturierung von Prozessen sowie Motorik und Sensorik behandelt und während einer Live-Demo veranschaulicht.
Alles in allem ein Thema, welches Programmierer und Tüftler, Profis und Unerfahrene sowie Erwachsene und Kinder gleichermaßen zu begeistern vermag.

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).

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!
