This session will focus on how users can access files in Perforce via a simple CRUD API, the subsystems exposed, and their usage.
PuppetCamp SEA 1 - Version Control with PuppetWalter Heck
Choon Ming Goh, System Administrator at OnApp Malaysia, gave a presentation on how OnApp implements version control. Since they have quite a few repositories, this is all puppetised and that is quite a nice way of doing version control.
File::CleanupTask is a CPAN module that the company I work at has opensourced. This is a presentation I gave about it at the London Perl Mongers technical meeting in August 2012.
Walter Heck, founder of OlinData, presented a step-by-step guide on how to set up a proper puppet repository, complete with the brand new PuppetDB, exported resources and usage of open source modules.

Wai Keen Woon, CTO CDN Division OnApp Malaysia, gave an interesting overview of what the Puppet architecture at OnApp looks like. The CDN division at OnApp is a large provider of CDN services, and as such makes a very interesting candidate for a case study.
Czy wiesz co potrafi zrobić twój serwer reverse-proxy? Wydaje Ci się, że żeby zrobić sprytny routing / uwierzytelnianie / autoryzację (niepotrzebne skreślić) między serwisami musisz go napisać w Javie lub jako moduł w C? A co jeżeli odpalanie JVM tylko po to, żeby do każdego żądania http dokleić jeden nagłówek to armata na wróbla? Zwłaszcza, że prawie na pewno gdzieś tam po drodze mijasz nginx...

Beyond Golden Containers: Complementing Docker with Puppetlutter
Often, Docker or more generally containers and immutable infrastructure are viewed as a replacement for configuration management. This talk explains why that is not the case, and that they are in fact complementary.
Containers move the challenges that configuration management solves to different places in the application lifecycle. The talk explains where Puppet fits into this changed lifecycle, and what tools Puppet provides there.

Le low-cost est un modèle qui a re-analysé le comportement des consommateurs et a su ré-interroger leurs besoins, pour les redéfinir dans le sens d’une simplification à l’extrême. L’offre hôtelière low-cost est dans un sens mise à nu, découpée, dépouillée de ses fonctions supplémentaires jusqu’à n’en retenir que le noyau, c’est-à-dire la fonction essentielle, celle qui satisfait le besoin principal de l’hébergement.
L'offre Low Cost en hôtellerie s'est développé grâce à de multiples politiques stratégies, et pratiques, ainsi que plusieurs facteurs qui ont contribué à son émergence.

Abstract: The wide adoption of configuration management and the increasing size and complexity of the associated code, prompt for assessing, maintaining, and improving the configuration code’s quality. We can leverage traditional software engineering knowledge and best practices to develop and maintain high quality configuration code. This talk brings the smell metaphor to configuration domain. This talk introduces configuration smells, their types with various examples, tools to detect them, and suggestions to refactor them.
Puppet for Java developers - JavaZone NO 2012Carlos Sanchez

Puppet is an infrastructure-as-code tool that allows easy and automated provisioning of servers, defining the packages, configuration, services,... in code. Enabling DevOps culture, tools like Puppet help drive Agile development all the way to operations and systems administration, and along with continuous integration tools like Jenkins, it is a key piece to accomplish repeatability and continuous delivery, automating the operations side during development, QA or production, and enabling testing of systems configuration.
Traditionally a field for system administrators, Puppet can empower developers, allowing both to collaborate coding the infrastructure needed for their developments, whether it runs in hardware, virtual machines or cloud. Developers and sysadmins can define what JDK version must be installed, application server, version, configuration files, war and jar files,... and easily make changes that propagate across all nodes.
Using Vagrant, a command line automation layer for VirtualBox, they can also spin off virtual machines in their local box, easily from scratch with the same configuration as production servers, do development or testing and tear them down afterwards.
We’ll show how to install and manage Puppet nodes with JDK, multiple application server instances with installed web applications, database, configuration files and all the supporting services. Including getting up and running with Vagrant and VirtualBox for quickstart and Puppet experiments, as well as setting up automated testing of the Puppet code.

The DevOps movement aims to improve communication between developers and operations teams to solve critical issues such as fear of change and risky deployments. But the same way that Agile development would likely fail without continuous integration tools, the DevOps principles need tools to make them real, and provide the automation required to actually be implemented. Most of the so called DevOps tools focus on the operations side, and there should be more than that, the automation must cover the full process, Dev to QA to Ops and be as automated and agile as possible. Tools in each part of the workflow have evolved in their own silos, and with the support of their own target teams. But a true DevOps mentality requires a seamless process from the start of development to the end in production deployments and maintenance, and for a process to be successful there must be tools that take the burden out of humans.
Apache Maven has arguably been the most successful tool for development, project standardization and automation introduced in the last years. On the operations side we have open source tools like Puppet or Chef that are becoming increasingly popular to automate infrastructure maintenance and server provisioning.
In this presentation we will introduce an end-to-end development-to-production process that will take advantage of Maven and Puppet, each of them at their strong points, and open source tools to automate the handover between them, automating continuous build and deployment, continuous delivery, from source code to any number of application servers managed with Puppet, running either in physical hardware or the cloud, handling new continuous integration builds and releases automatically through several stages and environments such as development, QA, and production.
Presentation on how Puppet has been introduced in Seat Pagine Gialle to automate system administration tasks and easy the cooperation between Ops and Others.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

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!

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
