Github Action is the CI/CD tool made by Github. Deeply integrated with Github features, it can not only automate deployments, but also Githu.b repository management. In this sharing I will talk about how we use Github action in LikeCoin and some issues we encountered.
"Building with Gradle" by Laurynas Tretjakovas.
A short introduction to Gradle. How to start using Gradle for Java projects and how does it compare to Maven and Ant.
GitHub is a Web-based Git repository hosting service. It offers all of the distributed revision control and source code management (SCM) functionality of Git as well as adding its own features. Unlike Git, which is strictly a command-line tool, GitHub provides a Web-based graphical interface and desktop as well as mobile integration. It also provides access control and several collaboration features such as bug tracking, feature requests, task management, and wikis for every project.
Do you want to make your releases safer, faster, and less effort? Lots of us now have microservices, kubernetes, maybe even a service mesh. So why are released still banned on fridays? Why is it so hard even know what version is running in production?

Front end microservices: architectures and solutionMikhail Kuznetcov
For latest version please open: https://www.slideshare.net/michailkuznetsov/front-end-microservices-october-2019
--
Modern frontend has grown in complexity and technologies diversity dramatically last decade. Usual case are apps of >100KLOC with multiple teams shipping code daily. One of the ways to deal with support and further growth of such projects is to apply microservices approach to frontend stack.
There are several solutions in the ecosystem that can enable multiple frameworks run seamlessly within one main uber-SPA. This enables common benefits of microservices approach: freedom of technology choice, separate deployments, faster new developers on-boarding due to reduced complexity of each sub-module, etc. Also this might be a migration path for large frontend monoliths.

Presentation abstract as in QCon session catalog:
LinkedIn and Mockito are two different use cases of implementing continuous delivery at scale. Yet the challenges, benefits and impact on the engineering culture are very similar.
In 2015, LinkedIn’s flagship application adopted a continuous delivery model we called 3x3: deploy to production 3 times a day, with a 3 hour maximum time from commit to production. At LinkedIn scale - hundreds of engineers building products for 500M users - implementing 3x3 was really hard. How did 3x3 change LinkedIn engineering culture and what we have learned on the way?
Mockito is a top 3 Java library with ~2M users. Even with that large user base, since 2014, the Mockito project has taken the surprising approach of publishing a new version of the library from every single pull request. This approach is challenging and innovative in the Java community, and Mockito leverages Shipkit to ship every change to production. Why did the Mockito team adopt continuous delivery in 2014 and what we have learned to date?
Join and learn from Szczepan Faber, the maker of Mockito framework since 2007, and the tech lead of LinkedIn Development Tools since 2015.

Multiplier Effect: Case Studies in Distributions for PublishersJon Peck
Join members from both Four Kitchens and Meredith Agrimedia as they discuss the experience of migration and relaunch of the digital presence of two magazines: Successful Farming at Agriculture.com and WOOD Magazine at woodmagazine.com.
We'll start by discussing the scope of the projects, delve into the commonalities and differences, explore their common advertising and analytics implementation, and analyze the unified distribution that supports both brands. By developing the infrastructure simultaneously, brand-agnostic functionality became a priority which in turn created a more modular and flexible system that facilitated open-sourcing and cross-organizational sharing. Thanks to the codebase approach and experience, the first site took about 6 months and the second took less than 6 weeks.

Kubernetes in Modern Application Architecture - Orkhan GasimovKuberton
Talk at Kuberton, 02/03/2019
Description: Kubernetes has become a real buzzword and winner in the battle for container orchestration. However, the key point from application point of view is not the container orchestration, but the architecture. We tend to use well known and battle-tested architectural styles and patterns. But, does Kubernetes change the architectural approaches? Or, does Kubernetes enable new patterns to benefit from? Let's overview modern approaches to application architecture, and see how Kubernetes enable new patterns and empower architecture for building modern

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).

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).

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!
