Advanced debugging techniques (PHP)
Step-by-step debugging with Xdebug is no secret for you? Perfect then, because we won’t talk about it. We will rather see tools that let you know what’s really happening in your PHP code, like the recent phpdbg debugger and phptrace, process tracing tools like: strace, ltrace, the Linux inotify mechanism, tcpdump/wireshark for network analysis,…
The Power Of Refactoring (PHPNW)
Refactoring involves restructuring existing code without changing its external behavior in order to improve aspects like readability, structure, and performance. It is done through a series of small, behavior-preserving changes. Refactoring can save time by improving code quality, allowing easier prototyping and changes when specifications are unclear, and helping to establish a clear overall project structure. It is important that refactoring does not break any existing functionality and keeps a consistent application programming interface.
The Power of Refactoring
Refactoring involves restructuring existing code without changing its external behavior through small, behavior-preserving transformations. It improves code readability, maintainability, and quality over time. Refactoring is useful for prototyping with unclear specs, gaining project overview on large codebases, and improving poorly designed code. It can save significant time versus rewriting from scratch by allowing work to progress iteratively while preserving existing functionality and APIs. Examples demonstrate how refactoring authentication and database code improved structure without affecting existing features or tests.
Debugging Drupal with Xdebug
This document discusses debugging Drupal with the PHP debugger extension Xdebug. It begins by explaining what Xdebug is and how it communicates with an IDE. It then covers installing Xdebug and configuring php.ini settings. The document contrasts debugging with and without Xdebug, highlighting Xdebug's advantages like stepping through code, inspecting variables, and changing values. It concludes by promoting a live demonstration of debugging basics in PHPStorm like watches and breakpoints.
Debugging and Profiling PHP Applications
This document discusses debugging and profiling PHP applications using Xdebug. It provides instructions for installing Xdebug on different platforms and configuring it for debugging and profiling. It also describes how to trigger debug sessions from PHPStorm, Chrome extensions, and JavaScript bookmarklets. Alternative profiling tools like MCG and XHProf are mentioned as well.
PHP Mega Meetup, Sep, 2020, Anti patterns in php
PHP is one of the easiest programming languages to use ever and powers more than half of the internet.
With this ease of use, certain common patterns emerge that become harmful. This is especially true when your product or service is not expected to die soon. Some anti-patterns are coding, others are related to operating your service, especially with new docker stacks. We will go over some of the most common pitfalls with a focus on enterprise development.
Docker jako prostředí pro automatizaci testů
The document discusses using Docker for test automation. It provides examples of pulling common test images like Selenium/standalone-chrome, running them in containers, and accessing their logs. It also discusses building custom Dockerfiles to create test stacks and publishing them to public or private repositories for automated builds. Finally, it lists some common Docker commands like run, logs, ps, stop and rm and introduces the SeleniumHQ automated test images as examples of prebuilt stacks that can help run tests in containers.

3 WAYS TO TEST YOUR COLDFUSION API
Most projects in CF now involve creating some type of consumable CFC Endpoint or API Service... do you Unit test your API, do you use Integration Tests on your API? How many ways do you test your API? Not all tests are created equal.
We build our CFCs and CF API to be consumed with CF Apps, Mobile Apps, Javascript apps and devices we haven’t even thought about yet. To be smart developers we need to be able to test our CFC endpoints, and the code that uses those endpoints.
We’ll learn how to test your API serverside with Testbox and Clientside with Jasmine.
With Testbox and Jasmine both using BDD, your test code can almost be isomorphic.
Attendees should have some exposure to CFCs as endpoints, or CF API creations, and consuming with other languages/devices, in this case, JavaScript.
Attendees will learn
How to use Testbox to test your CFCs 2 different ways
Different types and ways to test JavaScript

AN EXERCISE IN CLEANER CODE - FROM LEGACY TO MAINTAINABLE
We’ve all had those projects, the salvage project, the legacy project that we picked up, and wished we never had.
Was it written 5 years ago by that young dev with lots of passion but no big picture vision.
Was it written 6 months ago by another team, by a top gun developer who knows all the design patterns, and tried to future proof the app, only succeeding in making it impossible for anyone else to understand.
Or was it you, 2 years ago, before you joined the community and learned more about best (better) practices and you almost cannot comprehend how you used to code.
Long story short, we have all been there, but the past is history, how do we proceed from here, that’s the key. We’ll look at some of the ways you can clean up your code, and walk through some examples, and walk the journey to software craftsmanship

The problem with Perl
My ramblings about how I think the Perl community should target newcomers in its marketing efforts, and how I've come to appreciate Python and Java's standard libraries and toolsets.
Re-imaginging CakePHP
The document discusses planned changes and improvements for CakePHP 2.0, including dropping PHP 4 support, switching from SimpleTest to PHPUnit for unit testing, using SPL classes instead of reimplementing functions, throwing exceptions instead of using cakeError, improving the request/response system, making sessions more flexible through a session handler interface, improving JavaScript and XML handling, and moving the project to a beta and eventual stable release.
MyCPAN (Frozen Perl 2008 Lightning Talk)
The document discusses goals for creating a custom CPAN (MyCPAN) that contains only desired modules and versions. It describes using CPAN::Mini to build a local mirror (MiniCPAN) that can be pointed to by CPAN.pm instead of the public CPAN servers. The MiniCPAN can be updated from the network or contain additional private modules using CPAN::Mini::Inject.
CPAN Training
This document provides an introduction to CPAN (Comprehensive Perl Archive Network), which is a repository for Perl modules and programs. It discusses how to install and configure a local Perl installation and leverage CPAN to easily install additional modules without modifying the system-wide Perl installation. The document also covers how to configure CPAN settings, install and update modules manually or via the CPAN shell, and find information on module quality and reviews.
How do I write Testable Javascript - Presented at dev.Objective() June 16, 2016
Everyone who wasn't writing JavaScript, probably is now. Atwood's Law: any application that can be written in JavaScript, will eventually be written in JavaScript.
That's great, but how do we test it? In ColdFusion we have CFCs, most languages have classes... but JavaScript doesn't have classes (yet).
So how do I write unit tests, what units are there, and how do I make my code look like that? JavaScript is a flexible language, and with great flexibility comes great complexity and responsibility. Take your JavaScript spaghetti and make it unit testable.
Attendees should have some exposure to JavaScript, but this is for the Professional Newbie... who always needs to learn and adapt.
Daniel Sloof: Magento on HHVM
This document discusses using HHVM as a drop-in replacement for PHP to speed up Magento webshops. HHVM is a just-in-time compiler created by Facebook that translates PHP to bytecode and machine code, resulting in performance improvements of 5-10 times over regular PHP in some cases. While HHVM is not fully compatible with Magento, over 100 fixes have been contributed to HHVM to address Magento-related bugs. Benchmarks show significant improvements in response times and higher transaction rates when using HHVM with Magento compared to PHP.

Myphp-busters: symfony framework (PHPCon.it)
The document discusses common myths about the Symfony framework and attempts to dispel them. It addresses claims that Symfony is hard to learn, extremely coupled, not really programming but just configuration, restrictive, and badly performing. For each myth, counterarguments are provided explaining why Symfony is in fact easy to learn through documentation and community support, has become decoupled over time, allows for significant programming through controllers and custom code, is flexible through configuration, and can be optimized for performance.
Madison PHP 2015 - DevOps For Small Teams
DevOps is a large part of a company of any size. In the 9+ years that I have been a professional developer I have always taken an interest in DevOps and have been the "server person" for most of the teams I have been a part of. I would like to teach others how easy it is to implement modern tools to make their everyday development and development processes better. I will cover a range of topics from "Stop using WAMP/MAMP and start using Vagrant", "version control isn't renaming files", "Automate common tasks with shell scripts / command line PHP apps" and "From Vagrant to Production".
Myphp-busters: symfony framework
The document discusses common myths about the Symfony framework. It addresses criticisms that Symfony is hard to learn, extremely coupled, focuses only on configuration rather than programming, is restrictive, performs poorly, and claims it is the ultimate tool. For each myth, the document provides counter arguments explaining why Symfony is easy to learn with documentation and community support, has become less coupled over time, involves significant programming beyond just configuration, and allows for flexibility and customization. It also notes performance depends on caching and configuration choices.

Intro to Debugging PHP with Xdebug
How to install Xdebug and an overview of its basic features, including how to configure Xdebug in php.ini to work with NetBeans IDE.
Debugging PHP With Xdebug
Debugging in PHP can be tedious and prone to error when using var_dump and echo statements. Learn how to debug more effectively and get better insight into an application by using Xdebug. See how to setup PHPStorm, Xdebug, and the browser to enable debugging that will let you step into code and see variable values live. Extend those debugging capabilities into REST and SOAP clients to increase the code that can be debugged with ease.
PHP data structures (and the impact of php 7 on them), phpDay Verona 2015, Italy
We all have certainly learned data structures at school: arrays, lists, sets, stacks, queues (LIFO/FIFO), heaps, associative arrays, trees, ... and what do we mostly use in PHP? The "array"! In most cases, we do everything and anything with it but we stumble upon it when profiling code. During this session, we'll learn again to use the structures appropriately, leaning closer on the way to employ arrays, the SPL and other structures from PHP extensions as well.The impact that PHP 7 should have on data structures will be introduced as well.
Debugging Effectively - PHP UK 2017
Software bugs are inevitable; some are especially difficult to track down, causing you to waste countless hours before throwing your hands up in defeat. It doesn't have to be this way! The mental fatigue and wasted time can be avoided by using strategies like identifying the most-appropriate tool, taking a logical & objective approach, challenging assumptions, listening to variables, isolating the code path, and reinforcing code with automated tests. Attendees will learn how to combine these techniques with the right mindset and attitude in order to debug their code quickly and effectively.
Driving Design through Examples
Modelling by Example is a set of practices that combine BDD (Behaviour Driven Development) and DDD (Domain Driven Design) techniques to create a workflow that directly drives code from a starting point of user requirements. We will see how a simple feature can be defined via conversation with stakeholders, captured as automatable requirements, and expressed directly in the object model using tools such as Behat and PhpSpec.

The document argues that PHP remains widely used for websites and has a strong community and ecosystem backing it.
Start using PHP 7
Are you still on PHP 5.6-which will be EOL'd at the end of this year?! PHP 7 was released at the very end of 2015 and brought with it long awaited features to the PHP programming language while striving to keep backwards-compatibility. In this talk, I'll cover the new features including Static Type Hints, new operators, array de-referencing that you can use in your own Drupal modules to make your life easier. I'll also introduce a tool to assess how ready an existing PHP 5 codebase is to migrate to PHP 7.
Debugging WordPress with xDebug
You wouldn’t try and work out what’s wrong with your car engine by looking at the front bonnet.. so why debug your application from the outside when you can “pop the hood”?
The xDebug extension for PHP offers some amazing tools for developers to both understand and debug problems in their applications, but is frequently passed over as its benefits, setup, and configuration are poorly understood.
This talk aims to bring xDebug to the masses, discussing the setup of xDebug for a couple of local environments ( currently Local by FlyWheel, Laravel’s Homestead and Laravel’s Valet, though open to including more ‘WordPress’ environments like chassis ) and the configuration of your IDE ( VS Code / PHPStorm). Along with some demonstrations of how this method of working can help everyone take their development to the next level.

Kafka Summit talk (Bangalore, India, May 2, 2024, https://events.bizzabo.com/573863/agenda/session/1300469 )
Many Apache Kafka use cases take advantage of Kafka’s ability to integrate multiple heterogeneous systems for stream processing and real-time machine learning scenarios. But Kafka also exists in a rich ecosystem of related but complementary stream processing technologies and tools, particularly from the open-source community. In this talk, we’ll take you on a tour of a selection of complementary tools that can make Kafka even more powerful. We’ll focus on tools for stream processing and querying, streaming machine learning, stream visibility and observation, stream meta-data, stream visualisation, stream development including testing and the use of Generative AI and LLMs, and stream performance and scalability. By the end you will have a good idea of the types of Kafka “superhero” tools that exist, which are my favourites (and what superpowers they have), and how they combine to save your Kafka applications development universe from swamploads of data stagnation monsters!

Safelyio Toolbox Talk Softwate & App (How To Digitize Safety Meetings)
Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/

Speaker:
- Jianjian Xie (Staff Software Engineer, Alluxio)
As Trino users increasingly rely on cloud object storage for retrieving data, speed and cloud cost have become major challenges. The separation of compute and storage creates latency challenges when querying datasets; scanning data between storage and compute tiers becomes I/O bound. On the other hand, cloud API costs related to GET/LIST operations and cross-region data transfer add up quickly.
The newly introduced Trino file system cache by Alluxio aims to overcome the above challenges. In this session, Jianjian will dive into Trino data caching strategies, the latest test results, and discuss the multi-level caching architecture. This architecture makes Trino 10x faster for data lakes of any scale, from GB to EB.
What you will learn:
- Challenges relating to the speed and costs of running Trino in the cloud
- The new Trino file system cache feature overview, including the latest development status and test results
- A multi-level cache framework for maximized speed, including Trino file system cache and Alluxio distributed cache
- Real-world cases, including a large online payment firm and a top ridesharing company
- The future roadmap of Trino file system cache and Trino-Alluxio integration
