The document summarizes updates to the Jenkins project since its split from the Hudson project in 2011. It discusses the interim governance board, increased development activity and contributions from the community, initiatives to improve plugin development and testing, and plans for a stable but older release line and logo contest. The project is thriving with more users, developers, and formal governance processes since the split from Hudson.

DivorceInfra issues in java.net led to the question over the control by Oracle (Nov 2010)Trademark was used as a weaponLed to discussion with Oracle offline to transfer the trademark custody to 3rd party foundationNegotiation failed.

It notes the benefits of immutable infrastructure in allowing single line of code changes to be deployed on a reliable and repeatable basis, and also discusses using disposable environments for disaster recovery. The presentation raises questions at the end about these approaches.

Jenkins - From Continuous Integration to Continuous DeliveryVirendra Bhalothia

Continuous Delivery is a process that merges Continuous Integration with automated deployment, test, and release; creating a Continuous Delivery solution. Continuous Delivery doesn't mean every change is deployed to production ASAP. It means every change is proven to be deployable at any time. We would see how we can enable CD with Jenkins.

How to improve the quality of your applicationEUR ING Ioannis Kolaxis MSc

This document provides tips for improving software quality by focusing on frequently changing code and organizational structure. It recommends (1) refactoring the most complex and frequently changing files, (2) focusing testing on these files, and (3) paying attention to minor contributors and code ownership to reduce defects. Measuring changes at the file level and organizational metrics like minor contributors and ownership can provide insight into where to focus quality efforts.

Louisville Software Engineering Meet Up: Continuous Integration Using JenkinsJames Strong

Transforming Organizations with CI/CDCprime

When DevOps talks meet DevOps tactics, companies find that Continuous Integration is the make or break point. And implementing CI is one thing, but sustainable CI takes a little bit more consideration. CI is not all about releases, it is also about knowing more about how your software delivery pipeline works, it's weak points, and how you are doing over time. Join CloudBees and cPrime as we discuss best practices for facilitating DevOps pipelines with Jenkins Workflow and reveal how the workflow engine of Jenkins CI and “Agilecentric” Devops practices together, support complex control structures, shortens the development cycle, stabilizes environments and reduces defects.

Continuous Integration, Build Pipelines and Continuous DeploymentChristopher Read

This document discusses core concepts and best practices for continuous integration (CI), build pipelines, and deployment. It recommends having a single source code repository, automating builds and testing, publishing the latest build, committing code frequently, building every commit, testing in production environments, keeping builds fast, ensuring all team members can see build status, automating deployment, and making CI and continuous deployment a collaborative effort between developers and system administrators. The goal is to improve quality, time to market, and confidence through practices that provide fast feedback on code changes.

Enterprise CI as-a-Service using JenkinsCollabNet

The document describes a case study of CollabNet implementing a CI-as-a-Service solution for a large financial services company with over 4000 users across 100 teams developing over 150 applications using multiple technologies. The solution involved provisioning Jenkins servers on demand using Lab Management, integrating tools like TeamForge, Subversion, Nexus and SonarQube on a common platform to provide standardized CI tooling and processes managed by a dedicated build engineer. This helped establish a collaborative development culture, improve productivity and reduce costs.

On sharing ideas & sharing codeKohsuke Kawaguchi

The document discusses open commit policies and pull requests for sharing ideas in code. It argues that an open commit policy allowing all contributors direct commit access may no longer be necessary with tools like GitHub, and that pull requests can be just as effective for collaborating on ideas. However, too many restrictions or processes that create friction for contributors sharing ideas through code can negatively impact an engineering organization's ability to innovate and scale. The document advocates letting people innovate freely and fail fast by getting out of their way and allowing them to share ideas directly in code.

How we made jenkins communityKohsuke Kawaguchi

- Jenkins is an open source automation server with over 53,000 installations and 600+ plugins created by 500 contributors. It uses a modular architecture and extensibility model to enable large-scale distributed development. - Jenkins succeeded by focusing on extensibility through well-defined extension points, treating extensions as first-class citizens, enabling data and code extensibility, and ensuring extensions are themselves extensible. This reduced communication needs and lowered barriers to contribution. - An update center and shared resources like IRC provided a "center of gravity" to connect contributors and ensure the long-term maintenance of plugins. This self-reinforcing community allowed Jenkins to scale development through extensibility.

Build your own NES Emulator... with KotlinArtur Skowroński

For those who have ever wanted to recreate classic games, this presentation covers my five-year journey to build a NES emulator in Kotlin. Starting from scratch in 2020 (you can probably guess why), I’ll share the challenges posed by the architecture of old hardware, performance optimization (surprise, surprise), and the difficulties of emulating sound. I’ll also highlight which Kotlin features shine (and why concurrency isn’t one of them). This high-level overview will walk through each step of the process—from reading ROM formats to where GPT can help, though it won’t write the code for us just yet. We’ll wrap up by launching Mario on the emulator (hopefully without a call from Nintendo).

Supercharge Your AI Development with Local LLMsFrancesco Corti

In today's AI development landscape, developers face significant challenges when building applications that leverage powerful large language models (LLMs) through SaaS platforms like ChatGPT, Gemini, and others. While these services offer impressive capabilities, they come with substantial costs that can quickly escalate especially during the development lifecycle. Additionally, the inherent latency of web-based APIs creates frustrating bottlenecks during the critical testing and iteration phases of development, slowing down innovation and frustrating developers. This talk will introduce the transformative approach of integrating local LLMs directly into their development environments. By bringing these models closer to where the code lives, developers can dramatically accelerate development lifecycles while maintaining complete control over model selection and configuration. This methodology effectively reduces costs to zero by eliminating dependency on pay-per-use SaaS services, while opening new possibilities for comprehensive integration testing, rapid prototyping, and specialized use cases.

10. “Stable But Older” Release LineMain release lineThe main release line continues as isEach releases goes through all our automated testsFork a maintenance branch every 3 months from a releaseOnly proven backported fixes from mainlineMonthly releaseHopefully 1.400.1 in May

11. Goal of “Stable But Older” Release LineHelp those who value stability more than new featuresSlower release cycles, more conservative changesProvide focal point for people doing their own QAOften a team in large company does this

12. Plugin compatibility testingFrederic Camblor is driving this effortRerun plugin tests against the latest version of JenkinsShould help us catch regressions earlier

13. Plugins in JRubyCharles Lowell is driving this effortJenkins used more and more in languages like Ruby, PHP, PythonThose users would like to write plugins in their languages, not in JavaHopefully attract new wave of plugin developers

14. My Focus in CoreServe plugin developers technicallyMore extension pointsBetter cross-referencing existing pluginsTechnologies to simplify their codeServe plugin developers sociallyHackathons, documentationRestore infrastructure support

15. My Focus in CoreContinue housekeeping workImproved modularityBug fixes, better error diagnostics, smoothing out rough edgesBetter native packagingPush features along development themesBut do so by writing plugins
