Lightning talk presentation of Perl setup for Jenkins Continuous Integration platform. Notes and more information available at: https://logiclab.jira.com/wiki/display/OPEN/Continuous+Integration
Perl::Tidy formats Perl code to make it more readable by indenting, reformatting and applying coding standards. Perl::Critic analyzes Perl code and detects violations of best practices and coding standards to help improve code quality. Both tools can be configured using options and configuration files to customize formatting styles and select which coding standards to enforce.
This document provides an introduction to Perl Critic, which is a tool for static analysis of Perl code. It discusses what Perl Critic checks for, how it works, and how to configure it. Key points include:
- Perl Critic checks code against a set of predefined policies to find stylistic or logic issues
- It parses code as documents rather than executing it
- Policies have severity levels and can be grouped into themes
- Configuration options allow ignoring policies, changing severities, and applying themes
- Perl Critic can be run directly or integrated into testing to catch issues earlier
YAPC::NA 2007 - An Introduction To Perl Criticjoshua.mcadams
If you ever dreamed of having an instant code from some of Perl's top coders, Perl Critic may very well be the closest tool that you'll ever find. This talk will introduce you to Perl Critic, a static source code analyzer for your code. Learn about the ideas behind Perl Critic, the implementation of the system, and how to apply it and improve the quality and consistency of your code.
The document discusses using CGI::Application, Template::Toolkit, and DBIx::Class to create simple web applications in Perl. It provides an overview of MVC architecture and how these three modules separate code into the Model, View, and Controller components. It includes sample code for setting up a basic application using these modules, interacting with a database via DBIx::Class, and rendering views with Template::Toolkit.
This document provides an introduction and overview of using PHP as a scripting language for web programming applications in agricultural climatology. It covers background information on PHP and why it is suitable, basic syntax, variables and data types, control structures, functions, file input/output, and provides exercises for users to practice skills like reading weather data files and calculating cumulative growing degree units. The final section outlines a project exercise for users to build on the skills by reading a NASA weather data file and calculating thermal time between user-selected dates.
PHP extensions allow modifying and extending the PHP language. There are different types of extensions including wrapper extensions for interfacing with C libraries, speed and algorithm extensions for optimizing slow code, and Zend extensions for modifying the PHP engine. Writing extensions requires knowledge of C, the PHP internals including zvals and the PHP lifecycle, and using tools like phpize to generate the extension scaffolding. The document provides guidance on setting up a development environment, writing extension code, and testing extensions. It also outlines best practices for extension coding.
Hecl is a scripting language designed for mobile development that aims to be tiny, flexible, and simple; it is interpreted and dynamically typed, and can be embedded in Java applications to add scripting capabilities; the document discusses Hecl's features, syntax, embedding process, and how extensions can be created by writing Java classes that implement new commands.

Talk given at Agile Manchester 2016
Teams, projects and codebases can run into the ground very quickly if nobody takes care of the longer-term view. The law of entropy means that work must be done to prevent a slide into disorganisation and ultimately chaos. 'Code-rot' can set in and for apparently no reason, the team delivers less and less over time: what used to be a simple change now takes major effort.
If no account is taken of the effect of entropy on the code, its structure or even the build process itself then it becomes harder to change. Deliberate effort is required to fight entropy - to tidy code, to pull out common code, to introduce or improve structure. What was a greenfield codebase becomes a legacy before it's even launched. This slowly strangles the team, the project and ultimately the business - everyone's employer.
To business people (project managers, product owners) this might not be visible or understandable: even worse, the perception may be that the team has become lazy - where in reality they're working harder and harder just to keep the same pace. But they're trying to swim in treacle.
This session delves in to some of the common symptoms observed, described above, and fortunately some of the ways to address them. Agile practices give us the methods to do this: inspect and adapt. Learn the code by changing it; make sure you have a pyramid of tests from unit to system and make sure they're robust. Make larger structural changes by planning an evolution to get where you need to be. If code is repeating, then make it common. Remove out of date or just plain misleading comments.
But get them done or the project can quickly take a downhill spiral.
This session aims to be accessible for all, and might explain what the developer has been talking about all this time.

- Legacy Perl code is code that uses outdated practices, has no tests or documentation, and is difficult to understand and modify. It often results from organic growth over many years and developers.
- Unit testing legacy code provides safety during refactoring, speeds up development by replacing debugging, and creates regression tests. However, the code's dependencies make it difficult to isolate and test.
- Techniques like dependency injection, sprouting, monkey patching, and temporary object reblessing can help break dependencies and make legacy code more testable. Instrumentation with profilers also aids understanding the code.

The document summarizes the Easter story according to the Bible. It describes how Jesus' death by crucifixion fulfilled prophecies from the Old Testament. It then discusses Jesus' resurrection three days later, which proved he was the Son of God. The summary concludes by inviting readers to accept Jesus as their savior.
The document traces the origins and development of democracy from ancient Greece to the modern United States. It begins with Athens establishing a direct democracy in the 6th century BC where citizens voted directly on political issues, though it excluded slaves and women. Rome developed a republic with representatives elected by citizens to handle governance. During the Middle Ages, absolute monarchies replaced democratic rule in Europe. New democratic ideals emerged and influenced the framers of the US Constitution, which incorporated elements of direct democracy and republicanism with expanded rights compared to previous models.
This document provides biographical information about Brendan Seto, who was born on July 7, 1995 in Maine. It lists his interests as family, running, soccer, guitar, friends, and his soccer team. The document concludes by thanking the reader for watching.
Learn the latest in print technology: RFID technology embedded in paper. As costs for RFID and NFC tags continue to decrease, and phone manufacturers incorporate NFC capabilities into their products, RFID is being embraced in marketing campaigns, products, and events across the world. RFID in marketing brings a certain level of interaction to campaigns. Whereas traditional advertising campaigns push a message onto the consumer, interactive campaigns invite the consumer to engage with the brand.
Consumers have their smartphones or tablets in hand all the time. NFC (Near Field Communications) is a technology that invites consumers to connect directly with your advertisements, signage, displays, and other printed communications. NFC shortens the distance between inquiry and action. It lets customers spend more time engaging and making purchases through an interactive experience rather than just visiting a static web page.

It provides an overview of different testing techniques in Perl including writing unit tests, ensuring code quality and test coverage, and using the prove command-line tool to run tests.
This document provides best practices for writing PHPUnit tests, including: do not write tests that do not test anything or test too much; exploit dependencies between tests; use the most specific assertion; decouple test code from test data; organize tests by class; run tests via XML configuration; disable unnecessary PHPUnit features; use code coverage whitelisting; annotate tests to make coverage more meaningful; and avoid unnecessary patterns like singletons.
This document discusses unit testing in Laravel. It defines a unit test as checking a single assumption about system behavior. Key reasons for writing unit tests include making development faster and preventing bugs. The document outlines excuses for not testing and best practices like when to implement testing. It describes the typical arrange-act-assert structure of tests and introduces PHPUnit and Laravel testing helpers. Examples show how to test classes, pages, databases, sessions and models using assertions and Laravel helpers.
Testing Cassandra Guarantees under Diverse Failure Modes with Jepsenjkni
Jepsen tests were developed to test Cassandra's guarantees under diverse failure modes. The tests use the Jepsen library to interact with Cassandra clusters in a controlled way while inducing failures like network partitions and node crashes. The tests check for violations of invariants like consistent reads, writes, and counter operations. Several issues were found through these tests, including bugs affecting counter values, decommission race conditions, and write durability. Sharing the tests and results helped improve Cassandra.
DataStax: Testing Cassandra Guarantees Under Diverse Failure Modes With JepsenDataStax Academy
The increasing prevalence of large-scale distributed systems necessitates careful testing and understanding of the invariants and guarantees at play. In particular, Kyle Kingsbury's "Call Me Maybe" series has increased awareness of this need for developers and administrators alike. In this talk, Joel will discuss these issues in the context of his efforts as an intern at DataStax to develop extensive testing coverage via Kingsbury's Jepsen library.
perl often doesn't get updated because people don't have a way to know if their current code works with the new one. The problem is that they lack unit tests. This talk describes how simple it is to generate unit tests with Perl and shell, use them to automate solving problems like missing modules, and test a complete code base.
Short introduction to the basics of Perl testing and some resources for further reading. Includes basics of Test::Simple, Test::More, using Inline for multi-language testing, testing coverage, testing tests.
A lot of people using PHPunit for testing their source code. While I was observing my team I recognized most of them are only using the standard assertions like 'assertEquals()' and are complaining about how hard it is to test the code even when the tests are written first. This talk is about all the stuff not used on a daily basis and it digs deep into uncommon features of PHPUnit.
international PHP2011_Bastian Feder_The most unknown Parts of PHPUnitsmueller_sandsmedia
PHPUnit provides many features beyond just testing code including:
- Command line options like --testdox to generate styled reports and --filter to select specific tests.
- Annotations like @covers and @group to document and organize tests.
- Various assertion methods like assertContains(), assertType(), and assertSelectRegExp() to validate test conditions.
- Test listeners that get called at different test execution stages to add functionality.
- Ways to test exceptions like @expectedException and try/catch blocks.

Testing for Ops: Going Beyond the Manifest - PuppetConf 2013Puppet
"Testing for Ops: Going Beyond the Manifest" by Christopher Webber, Infrastructure Engineer, Demand Media.
Presentation Overview: This talk aims to show the value of rspec-puppet for those who come from a more Ops-centric background. The focus will be on using tests to go beyond just rewriting manifests in rspec. Instead the focus will be on scenarios like: - Are the baseline security measures in place? - Do the differences between dev and prod get reflected? - Are the config elements that are core to the application present? In addition, tests will help to be a place to help document the oddities of our configurations and ensuring that minor changes don't result in catastrophe.
Speaker Bio: After beginning his career at UC Riverside supporting enterprise operations and bioinformatics research, Chris is now rocking being an infrastructure engineer at Demand Media in Santa Monica. He currently supports large high-traffic sites like eHow.com, LiveSTRONG.com, and Cracked.com. Chris enjoys attending local meetups, writing new Puppet modules, and creating small tools to make his team's lives a little easier. Find him on Twitter as @cwebber.
Markdownlint is a linter tool that checks Markdown files for formatting errors and inconsistencies. It helps ensure correctness, uniformity, and consistency across large documentation sets or multiple documents. There are Ruby and Node.js implementations of Markdownlint that define rules for formatting and can be integrated into text editors, command line, and continuous integration tools like Travis CI to catch basic Markdown issues before committing changes.
This document discusses building RESTful interfaces using the Mojolicious framework in Perl. It notes that implementing REST with Mojolicious is easy, but can lead to an anti-pattern of encoding media types in URLs instead of using accept headers. The recommended practice is to use accept headers to specify media types rather than encoding them in the URL. The document provides an example of using Mojolicious to respond with different media types depending on the accept header.
Stackato is a PaaS cloud platform from ActiveState that allows developers to easily deploy applications to the cloud. It supports multiple languages including Perl, Ruby, and JavaScript. The presentation demonstrated deploying simple Perl apps to Stackato using the Mojolicious framework. Key benefits of Stackato include minimal differences between development and production environments, one-click deployments, and allowing developers to manage infrastructure. ActiveState is very open and provides documentation, examples, and a community forum to support Stackato users.

Stackato is a cloud solution from renowned ActiveState. It is based on the Open Source CloudFoundry and offers a serious cloud solution for Perl programmers, but also supports Python, Ruby, Node.js, PHP, Clojure and Java.
Stackato is very strong in the private PaaS area, but do also support as public PaaS and deployment onto Amazon's EC2.
The presentation will cover basic use of Stackato and the reason for using a PaaS, public as private. Stackato can also be used as a micro-cloud for developers supporting vSphere, VMware Fusion, Parallels and VirtualBox.
Stackato is currently in public beta, but it is already quite impressive in both features and tools. Stackato is not Open Source, but CloudFoundry is and Stackato offers a magnificent platform for deployment of Open Source projects, sites and services.
ActiveState has committed to keeping the micro-cloud solution free so it offers an exciting capability and extension to the developers toolbox and toolchain.

AI Changes Everything – Talk at Cardiff Metropolitan University, 29th April 2...Alan Dix
Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025

Is AI just another technology, or does it fundamentally change the way we live and think?
Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater.
At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts.
At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.
