DevOps for Humans - Ansible for Drupal Deployment Victory!Jeff Geerling
Everyone knows it's a Good Idea™ to use a configuration management system (e.g. Puppet, Chef) to manage your Drupal infrastructure. But many people (myself included) have run into a wall of #wtfmoments when trying to learn the vagaries of traditional CM systems and their vendor-specific syntaxes.
In 2012, Ansible was released, enabling normal human beings to manage their servers with an easy, but powerful, CM system that uses YAML (just like Drupal 8!) to define configuration and Jinja2 (very much like Twig!) for templates. Not only that, but Ansible is also an incredibly simple and very flexible Drupal deployment and continuous delivery tool.
Learn how you can use Ansible to manage your infrastructure—including local development environments—and stop letting servers and deployments get in the way of development.

MacDevOpsYVR 2016 Talk on osquery, Google Santa technologies managed with Zentral TLS Server and event/filter/action Framework.
http://www.macdevops.ca/
If you are starting to ask questions about your IT infrastructure and want to know what is happening on your clients, osquery - an open source technology, developed by the Facebook engineering team - is an interesting and promising technology. It can be used for intrusion detection, infrastructure reliability or compliance checking. With osquery you gain deep insight into your endpoints. While osquery delivers a broad set of tools, ranging from collecting metrics, state checks and I/O monitoring to file system integrity checks, Google Santa is a security technology developed by the Google MacOps team, that is focused on white- and blacklisting of binaries on macOS. Together, osquery and Santa form the technological base for the Information and Event Monitoring and Notification tool called Zentral. Zentral is a TLS server for deploying the required configurations and aggregating the results. Zentral can filter the results and notify users on any changes, additions and triggered events on the clients monitored. Zentral can also automatically react on those events, and trigger external actions, like creating tickets in a ticketing system or interact with client management software.

Anybody looking at being more effective with Hadoop will also learn best practices and how to quickly get ramped up on the main data scenarios. Hue can be integrated with existing Hadoop deployments with minimal changes/disturbances. We cover details on how Hue interacts with the ecosystem and leverages the existing authentication and security model of your company.
To sum-up, attendees of this talk will learn how Hadoop can be made more accessible and why Hue is the ideal gateway for using it more efficiently or being the starting point of your own Big Data Web application.
From Dev to DevOps - Apache Barcamp Spain 2011Carlos Sanchez
UPDATE: updated slides at http://www.slideshare.net/carlossg/from-dev-to-devops-conferencia-agile-spain-2011
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.

The new Lumberjack is now stable and ready for use!
This talk is aimed at anyone involved in working with WordPress, regardless of how technical you are. The beauty of Lumberjack is that you can use as much or as little as you like, so whether you’re new to web development or a seasoned software engineer there will be something here for you.
Drupal Camp Brighton 2015: Ansible Drupal Medicine showGeorge Boobyer
In this session we are going to look at the latest craze amongst developers with some Sysadmin responsibilities - Ansible.
As with all trending technologies you can be led to believe that it is the new wonder drug (multi purpose in a jar - if you ain't ill it will fix your car). But in this case we will look at some of the key ways that automated provisioning, configuration and state management can actually cure some of the critical headaches you face securing and managing production infrastructure and Drupal sites - (as with all such wonder drugs seek the advice of your GP before radically changing your lifestyle). Also as a warning once you start delving deeper into the world of web security you'll need a pretty thick skin - denial was a comfortable place to be. We won’t be covering Ansible for use in local development with systems such as VLAD - that hopefully will be the subject of other presentations.
Critically we are going to look at Ansible in a Drupal context with a focus on security and hopefully encourage participation in the development of tighter integration with Drupal site deployment and management as well as security defence measures.
By the end of the session we hope to have been convinced that with the adoption of Ansible you will feel more secure, more efficient and more relaxed about managing your infrastructure and sites and also to show how the principles of collaboration common within the Drupal community can transpose with great effect to the Ansible community . Code examples will be provided to support the topics covered.
Streamline Hadoop DevOps with Apache AmbariJayush Luniya
Ambari talk at Hadoop Summit, Tokyo 2016
Abstract
Apache Ambari has become an indispensable tool for operating Hadoop clusters from as small as 10s of nodes to 1000s of nodes. Ambari’s deep knowledge of the Hadoop stack allows it to deploy a cluster within minutes and manage the entire lifecycle: scaling, security, upgrades, and more. This talk will cover the central features important to cluster operators and the latest innovations from the community. We will discuss automatically deploying clusters with Blueprints, adding custom services, scaling the number of hosts as the data needs grow, adding High Availability for critical services, securing with MIT kerberos, and upgrading the Hadoop stack with features like Rolling & Express Upgrade. More advanced users will also be interested in using Ambari’s powerful REST API to automate workflows. For users and data scientists, Ambari provides LDAP sync, Role-Based Access Control to handle user permissions, and a framework to host Ambari Views such as as the newly added Views for Hive, Oozie, Capacity Scheduler, Tez, Storm, and Zeppelin. Lastly, we will cover how to monitor the health of the cluster via Alerts and troubleshoot problems by using new features like LogSearch and Ambari Metrics Systems integrated with Grafana UI.
This is the Apache Spark session with examples.
It gives a brief idea about Apache Spark. Apache Spark is a fast and general engine for large-scale data processing.
By the end of this presentation you should be fairly clear about Apache Spark.

Building your macOS Baseline Requirements MacadUK 2018Henry Stamerjohann
Slides from 2018 MacAD.UK confernce
Synopsis: https://www.macad.uk/speaker/henry-stamerjohann/
When tasked with (re)building a security baseline for macOS clients, where do you start?
There’s obviously decisions to be made about what’s feasible in your organization (beyond if admin privileges should be the default). You need to weigh system stability and security with end-user productivity. Luckily for the macOS platform a rich ecosystem of tools exist to fill in the gaps and general guidance is available. The crucial part of making mindful and informed decisions is to first aggregate data from your IT environment. You can then decide what configurations to deploy and run recurring compliance checks based on an appropriate strategy. This session will cover fundamentals, highlight advanced considerations, and outline practical examples to apply when you’re conducting a (new) baseline for macOS clients.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

11. Ansible(Basic(Terminology:(
• Modules - accomplish dedicated Tasks (set values, use templates)
• Tasks - execute Module specific parameters, variables, etc.
• Variables - configuration-wide, Playbook / Roles specific vars
• Facts - gather information about the target system
• Handlers - like Tasks but usually get called by another Task
• Roles - group related Tasks, encapsulate data to accomplish Tasks
• Files - files directory contains files copied over to target
• Templates - Jinja2 format w/ placeholders to insert variables
• Vault - encrypt sensible data (i.e. files containing passwords)
• Plays - are lists of Tasks which apply to hosts / host groups
• Playbooks - YAML formatted files orchestrate steps sequentially
• Inventory - reference inside 'host' & 'ansible.cfg' files
