Why Puppet? Why now? Can you get by without using any config management? You probably think don't have time, or that your project is too small. What can using Puppet really add? How can you justify investing time up front? Maybe you can just do it later?
Getting started with config management can often seem like a big project, especially if you only manage a few systems or have a small team. This talk will examine why you should use Puppet from the beginning. It will examine what you can do with Puppet that couldn't do otherwise, how much time it will save and why it's especially important if you think your project has even the smallest chance of scaling in the future.
Presented by David Mytton at Puppet Camp London 2015-04-13
WP-CLI is a command line interface tool that allows users to manage WordPress from the command line. It is useful for developers, theme designers, and server administrators. To use WP-CLI, one needs SSH access and a "UNIX-like" environment like Linux, OSX, or Cygwin. Installing WP-CLI involves downloading the phar file, setting permissions, and moving it to a useful location like /usr/local/bin/wp. Common commands include installing and managing plugins, interacting with the database, searching and replacing content, generating test content, and more.
The document discusses the DevOpsSec approach which aims to integrate security testing into the development process through automation. It outlines how DevOpsSec can help address issues that arise from the traditional separation of development and operations teams. The document provides examples of different types of tests that can be automated, such as unit testing, performance testing, and security testing of an application's attack surface. It promotes automating as many tests as possible and sharing test automation code to continuously monitor for vulnerabilities and issues.
Being able to rapidly iterate on, build, and test your code is key to being a productive developer.

Custom Coded Projects - When picking up a project you have many choices to make. Do you go for a premium theme and already builded plugins or will you write parts yourself. I will discuss what impacts custom building a project can have. I will focus on time, cost and speed to help you out with your decision making with future projects.
Go is a compiled language that compiles to a single binary without needing a virtual machine. It has built-in support for easy concurrency using goroutines and channels that allows for simple yet powerful communication. Writing servers in Go is also easy due to its powerful and production-ready net/http library, and the code is clean and minimal due to automatic formatting tools and standard practices around the language. The standard library is also very full-featured so most needs are met out of the box, and the language is designed to be easy to use, learn and get started with through commands like "go get", "go build", and "go test".
Conditional Logging Considered Harmful - Sean ReillyJAXLondon2014
The document discusses the issues with conditional logging frameworks and advocates for an alternative approach using enum-based logging designed specifically for operations. It proposes logging through enums where each value has a unique code and format string. The output is designed to be easy to read and parse. An open source Java library called OpsLogger is introduced that follows this pattern and is testable, generates documentation, and is optimized for log file rotation.

How effective is the combination of your main product...martellewilson
The document discusses the integration of time as a theme in a film trailer, poster, and magazine advertising package. In the trailer, every time the clock reads "11:57" the main character reacts negatively, hinting at why he is mentally unstable. Both the trailer and poster feature the time "11:57" and the tagline "lost time is never found again" to raise questions about the time's significance. The poster and trailer also portray the main character's psychological breakdown as he tries to repress memories of a woman named Lisa. The color schemes, images, and text in the advertising package work together to successfully convey the film's themes and intrigue potential audiences.
Analysis of Human to Human Tutorial Dialogues: Insights for Teaching AnalyticsIrene-Angelica Chounta
This document discusses research on analyzing human tutorial dialogues to understand how to best support learning. It aims to develop an adaptive tutorial system guided by a student model. The research questions examine what makes tutorial dialogue successful and how dialogues adapt to different student characteristics. The study analyzed 3 human tutorial dialogues on physics to build a coding scheme to operationalize "levels of support." The coding scheme was then applied and evaluated on 10 additional dialogues. Lessons learned were that providing appropriate adaptive dialogic support is complex and depends on individual students. Future work could involve experts designing dialogic support for different student types.

Trent Hornibrook gave a recent talk at the Infracoders meet-up playing a thought experiment with the audience on 'what would be your tech decisions if you were given a blank cheque at at startup'.
Trent, recently working for a start-up then shared what decisions he made, and why
- The team created a content inventory spreadsheet to audit and organize all website content. This involved building a sitemap, indexing documents, and identifying duplicates.
- They used Mercurial for version control due to its ease of use, cross-platform support, and ability to clone repositories for branching.
- A CSS style guide was created as a reference for developers, demonstrating classes and IDs without being a full framework or coding specification.
At UCR, automation is a part of everything we do.

Journey to Docker Production: Evolving Your Infrastructure and Processes - Br...Docker, Inc.
DevOps in the Real World is far from perfect, and we're all somewhere on the path to one day writing that "Amazing-Hacker-News-Post about your chat-bot fully-automated micro-service infrastructure." But until then, how can you *really* start using containers today, in meaningful ways that impact yours and your customers productivity? This session is designed for practitioners who are looking for ways to get started now with Docker and Swarm in production. No Docker 101 here, this is for helping you be successful on your way to Dockerizing your production systems. Attendees will get tactics, example configs, real working infrastructure designs, and see the (sometimes messy) internals of Docker in production today.
Drupal and its contributed modules provides an impressive amount of functionality without needing to write a single line of code by storing information in Drupal’s database tables. Unfortunately this poses a challenge for developers wanting to stage changes between servers. This talk starts to address these issues by describing the problem and presenting a variety of solutions as well as their pros and cons. I also discuss some possible paths to make this easier coming down the pipe.
Deploying distributed software services to the cloud without breaking a sweatSusan Potter
The document contains the output of multiple "finger" commands run on the user "susan". It shows Susan Potter is logged in from tty1 and has been on since 1997. It also lists her home directory, shell, and social media accounts. The remaining content discusses the scope of a talk and covers various DevOps and cloud computing topics at a high-level, including delivery models, characteristics, definitions, deployment pipelines, bottlenecks, and automation approaches.
Distributed software services to the cloud without breaking a sweatJosé Ferreiro
The document contains the output of multiple "finger" commands run on the user "susan". It shows Susan Potter is logged in from tty1 and has been on since 1997, with no mail and social media accounts listed. The remaining content discusses the scope of a talk, covering approaches, best practices, pitfalls and possibilities, but not specific comparison topics. It also contains sections about cloud computing models, DevOps definitions and principles, deployment pipelines, common bottlenecks, and automation approaches.
The document discusses challenges with deploying a SaaS platform on-premises for customers. It notes that automation and tools developed for internal use may not work well for external customers due to different constraints around access, networking, security policies and variability between customer environments. Deploying on-premises requires implementing customizations for each unique customer setup, reduces ability to easily fix issues, and significantly increases costs compared to hosting in one's own infrastructure. The document recommends choosing a SaaS model over on-premises if possible to avoid these challenges.
The business case for contributing codeZivtech, LLC
In the Drupal community we tend to talk about committing code to our public spaces (drupal.org, but also github) in terms of "contributing" and "contributions", and while much of it can be seen in that light, there are actually very strong business reasons for publishing your code and/or attempting to get your code changes committed to the open source project that you are working on.
We will be looking at several documents from the U.S. Military detailing their recommendations for contracting Open Source Software services, and will use those as a jumping off point to discuss the many benefits of contributing code. Some of the business reasons for public publishing we'll explore will include:
* The power of peer review. With enough eyes, all bugs are shallow, and with only a few eyes the stupidity knows no depths!
* Fork you! The costs associated with "hacking" both Drupal core and contrib modules and base themes.
* Take my code, please! Cost savings from committing patches.
* Professionals publish or perish. Using code commits as marketing towards clients or potential hires.
* It's so easy, even a child(ish person) could do it! How you can easily integrate patching into your development workflow.
This session will also include a walk through of how Zivtech handles code review, patches, and deployment processes and you will hopefully walk away convinced that all of your in-house and out-sourced developers should be publicly committing their work.

'Intro to Infrastructure as Code' - DevOps BelfastJohn Fitzpatrick
This document provides an introduction to infrastructure as code and Chef. It discusses how infrastructure as code treats infrastructure configuration like code that can be version controlled, tested, and managed declaratively. It then introduces Chef concepts like resources, recipes, cookbooks, and how they allow defining infrastructure in a declarative way using Ruby DSL. The document uses examples like package, file, template and service resources to illustrate how Chef models infrastructure as code.
Devconf 2011 - PHP - How Yii framework is developedAlexander Makarov
This document discusses the development of the Yii PHP framework. It was originally developed from Prado in 2004 and became Yii 1.0 in 2008. The framework uses an MVC architecture and takes inspiration from other frameworks like Rails and Symfony. It focuses on being easy to use, powerful, and flexible. The framework is developed as an open source project under the BSD license to encourage contributions from the community.
This document discusses various strategies for backing up MongoDB data to keep it safe. It recommends:
1. Using mongodump for simple backups that can restore quickly but may be inconsistent.
2. Setting up replication for high availability, but also using mongodump for backups and testing restore processes.
3. Taking snapshots of the data files for consistent backups, but this requires downtime and gaps can occur between snapshots.
4. Using the oplog for incremental, continuous backups to avoid gaps without downtime using tools like the Wordnik Admin Tools. Testing backups is strongly recommended.
Make It Cooler: Using Decentralized Version Controlindiver
A commonly used version control system in the ColdFusion community is Subversion -- a centralized system that relies on being connected to a central server. The next generation version control systems are “decentralized”, in that version control tasks do not rely on a central server.
Decentralized version control systems are more efficient and offer a more practical way of software development.
In this session, Indy takes you through the considerations in moving from Subversion to Git, a decentralized version control system. You also get to understand the pros and cons of each and hear of the practical experience of migrating projects to decentralized version control.
Version control is often used in conjunction with a testing framework and continuous integration. To complete the picture, Indy walks you through how to integrate Git with a testing framework, MXUnit, and a continuous integration server, Hudson.
This document provides an overview of DevOps concepts like DebOps and Chef. It discusses how Chef can be used to manage infrastructure as code through cookbooks, nodes, attributes, templates and other resources. Challenges with traditional infrastructure management like complexity and risk are addressed through DevOps approaches like Chef which enable stable, reliable and auditable infrastructure through self-healing automation and configuration as code. Key Chef concepts like the chef-client, nodes, attributes, templates, files, roles, environments, data bags, and Test Kitchen are defined to explain how infrastructure can be managed from code through the Chef platform.
The document discusses how content marketing is a path to reaching customers' goals, not just a company's marketing goals. It emphasizes creating high-quality, useful content that serves customers' needs over superficial or keyword-focused content. The key is developing content that provides long-term value for customers through discipline, honesty and developing one's unique voice.
This document discusses improving incident response procedures through practices such as checklists, documented procedures, realistic incident simulations and postmortems. It recommends extended use of checklists to guide responses while still allowing for experience and independent thought. Regular incident response simulations that test both general processes and specific failures can help refine procedures and build confidence. Postmortems should objectively review incidents, suggest improvements and run through scenarios again over time to prevent complacency.
The document discusses how to handle incidents, downtime, and outages. It notes that the cost of downtime for companies in Q1 2015 was $2.9 billion, $870 million, and $4.1 billion. It recommends preparing for incidents by having on-call staff and documentation, responding quickly by following an incident response checklist and notifying stakeholders, and performing a postmortem within days to analyze what failed and how to prevent future issues.
Scaling humans - Ops teams and incident managementServer Density
The document discusses the costs of downtime for companies and best practices for incident management teams to prepare for, respond to, and review incidents to minimize downtime costs. It notes that downtime costs companies billions per quarter and recommends teams prepare documentation and contact information, have on-call rotation schedules, log all responses to incidents, provide frequent status updates, gather teams to escalate incidents as needed, and conduct post-mortem reviews within days of an incident.
Containers seem to have suddenly become the hot new thing everyone is talking about, but what are they?
Why are they important?
How should you use them and what does it mean for cloud infrastructure? This talk will examine the history, technical details and strategy around containerisation from the perspective of developers and operations, consider internal container OSs like Rocket and Ubuntu Core as well as management layers like Docker and Apache Mesos and take a look at why cloud providers are launching their own services around them.

Infrastructure choices - cloud vs colo vs bare metalServer Density
This document discusses the differences between cloud, colocation, and bare metal infrastructure options. It covers key considerations for performance including CPU, memory, disk, and network latency and bandwidth. Colocation provides hardware at a specific location while maintaining internal skills, but has costs for total spend, hardware specifications, and power usage. Cloud infrastructure offers elastic workloads and support for demand spikes and unknown requirements, but bare metal is preferable for managed hardware replacement and networking needs. Overall, the best option depends on an organization's specific workload characteristics and skills.

DevOps Incident Handling - Making friends not enemies.Server Density
David Mytton CEO of Server Density presented this talk to the DevOps Meetup in London. It takes you through how to handle DevOps incidents, outages and downtime -- and more specifically how to make friends, not enemies in the process.
Joined by Rick Nelson, Technical Solutions architect from NGINX Server Density take you though the do's and don'ts of monitoring NGINX. Critical and non critical metrics to monitor, important alerts to configure and the best monitoring tools available.
David Mytton is a MongoDB master and the founder of Server Density. In this presentation David delves deeper into what's discussed in our how to monitor MongoDB tutorial (https://blog.serverdensity.com/monitor-mongodb/), with the aim of taking you through:
Key MongoDB metrics to monitor.
Non-critical MongoDB metrics to monitor.
Alerts to set for MongoDB on production.
Tools for monitoring MongoDB.
The document discusses high performance infrastructure for Server Density which includes 150 servers that have been running since June 2009 and migrated from MySQL to MongoDB. It stores 25TB of data per month. Key aspects of performance discussed are using fast networks like 10 Gigabit Ethernet on AWS, ensuring high memory, using SSDs over spinning disks for performance, and factors like replication lag based on location. The document also compares options like using cloud, dedicated servers, or colocation and discusses monitoring, backups, dealing with outages, and other operational aspects.
The document discusses Server Density's architecture which includes 100 Ubuntu servers with 50% being virtual, using Nginx, Python, and MongoDB. It handles 25TB of data per month. Puppet is used for configuration, failover, code deploys, and system updates. The document also considers colocating servers versus using a dedicated provider and factors like hardware specs, costs, skills required, and fun.
NoSQL databases are often touted for their performance and whilst it's true that they usually offer great performance out of the box, it still really depends on how you deploy your infrastructure. Dedicated vs cloud? In memory vs on disk? Spindal vs SSD? Replication lag. Multi data centre deployment.
This talk considers all the infrastructure requirements of a successful high performance infrastructure with hints and tips that can be applied to any NoSQL technology. It includes things like OS tweaks, disk benchmarks, replication, monitoring and backups.
Remote startup - building a company from everywhere in the worldServer Density
This document discusses how Server Density grew from 2 employees in 2009 to 12 employees in 2013 while being fully remote. It outlines the company's timeline and some advantages of being fully remote such as access to worldwide talent, lower costs, and no distractions of an office. However, it also notes disadvantages like collaboration being more difficult without in-person interactions. While the company added an office in 2012, the document emphasizes that working remotely is a mindset that is difficult to adopt after initially co-locating. Effective communication and availability are important for fully distributed teams.
This document discusses MongoDB infrastructure at Server Density. It notes that Server Density uses 27 MongoDB nodes to store 20TB of data per month from their MySQL database. Some key reasons for choosing MongoDB include replication, official drivers, easy deployment, and fast performance out of the box. The document then discusses various MongoDB performance and infrastructure considerations like network throughput, replication lag, failover processes, disk types, backups, and monitoring.
StartOps: Growing an ops team from 1 founderServer Density
Bootstrapped startups don't have the luxury of a full team of ops engineers available to respond to issues 24/7, so how can you survive on your own? This talk will tell the story of how to run your infrastructure as a single founder through to growing that into a team of on call engineers. It will include some interesting war stories as well as tips and suggestions for how to run ops at a startup.
Presented at DevOpsDays London 2013 by David Mytton.
MongoDB: Optimising for Performance, Scale & AnalyticsServer Density
MongoDB is easy to download and run locally but requires some thought and further understanding when deploying to production. At scale, schema design, indexes and query patterns really matter. So does data structure on disk, sharding, replication and data centre awareness. This talk will examine these factors in the context of analytics, and more generally, to help you optimise MongoDB for any scale.
Presented at MongoDB Days London 2013 by David Mytton.
Test Polarity: Detecting Positive and Negative Tests (FSE 2024)andrehoraa
Positive tests (aka, happy path tests) cover the expected behavior of the program, while negative tests (aka, unhappy path tests) check the unexpected behavior. Ideally, test suites should have both positive and negative tests to better protect against regressions. In practice, unfortunately, we cannot easily identify whether a test is positive or negative. A better understanding of whether a test suite is more positive or negative is fundamental to assessing the overall test suite capability in testing expected and unexpected behaviors. In this paper, we propose test polarity, an automated approach to detect positive and negative tests. Our approach runs/monitors the test suite and collects runtime data about the application execution to classify the test methods as positive or negative. In a first evaluation, test polarity correctly classified 117 tests as as positive or negative. Finally, we provide a preliminary empirical study to analyze the test polarity of 2,054 test methods from 12 real-world test suites of the Python Standard Library. We find that most of the analyzed test methods are negative (88%) and a minority is positive (12%). However, there is a large variation per project: while some libraries have an equivalent number of positive and negative tests, others have mostly negative ones.
