Continuous DB Changes Delivery With LiquibaseAidas Dragūnas
The short overview of Continuous Delivery process. The overview of Liquibase technology as one of open source technologies, designed for DB changes migration. Live demonstration of how Liquibase could be used in Continuous Delivery process.
JDBC has been the de-facto standard for accessing relational databases for a long time. Times are however changing. In cloud environments the pay-per-use model is popular. If you can use resources more efficiently, you can save money! In addition, when running applications at cloud-scale, the number of concurrent requests which hit your services can skyrocket. Can JDBC handle such concurrency efficiently? Answer: No. The time has come to look beyond JDBC!
For services, reactive frameworks are becoming more popular. These frameworks can make more efficient use of resources due to their non-blocking nature, especially at high concurrency. Now with R2DBC relational databases can also be accessed using a reactive API! This means more efficient use of CPU and memory and better response times and throughput at high concurrency.
A tempting story but there are of course many questions
- Is R2DBC mature enough to implement?
- Which R2DBC drivers are available?
- Is framework support available?
- What do you need to do in order to implement R2DBC?
- Does it improve performance enough to make the switch worthwhile?
- Do I need to have a completely non-blocking stack to benefit from using R2DBC?
To answer these questions and more, I've created several implementations using R2DBC and JDBC with Spring Web MVC and Spring WebFlux and put them to the test. I looked at how to implement R2DBC and measured resource usage, throughput, and responsetimes. Interested in the results? Hint: R2DBC is pretty cool!
Database Migrations with Gradle and LiquibaseDan Stine
Database migration scripts are a notorious source of difficulty in the software delivery process. This session will discuss how we neutralized this all too common headache.
Now our deployment framework executes database migrations automatically with every application deploy, and the QA team performs self-service full stack deployments in test environments. The resulting additional bandwidth has been invested in more frequent software releases, and the opportunity to focus on higher-value tasks.

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.

Project Lambda: Functional Programming Constructs in Java - Simon Ritter (Ora...jaxLondonConference
Presented at JAX London 2013
The big language features for Java SE 8 are lambda expressions (closures) and default methods (formerly called defender methods or virtual extension methods). Adding lambda expressions to the language opens up a host of new expressive opportunities for applications and libraries. You might assume that lambda expressions are simply a more syntactically compact form of inner classes, but, in fact, the implementation of lambda expressions is substantially different and builds on the invokedynamic feature added in Java SE 7.

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.

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.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).
