Top 10 Scalability Mistakes
A very successful talk where in I discuss the top 10 failures of organizations I have personally experienced when trying to scale. More than just performance!
2013 - Dustin whittle - Escalando PHP en la vida real
This document discusses how to scale PHP applications to meet high demand. It begins by noting that large companies like Facebook and Wikipedia use PHP. It then outlines several techniques for scaling PHP, including: using opcode caches to improve performance; storing sessions in a database rather than disk; leveraging in-memory data caches like Memcached and Redis; doing blocking work in background tasks via queues; and utilizing HTTP caching with a reverse proxy cache. The document emphasizes that performance is important for user experience and business results, and that these techniques can help PHP applications handle high traffic loads.
Speed kills
Speed Kills. More accurately the lack of speed kills. It kills your visitors waiting for a page to load. It kills the search engines trying to index your site. It kills your number of page views, your rankings, your conversions, your user experience, your revenue, and the reach of your message.
This presentation is all about tips and tricks for smaller Drupal sites to speed them up like the big boys at low or no cost.
At A Small Orange we have a large number of clients who love Drupal and also love a value. We've learned a few things about site speed hosting Drupal sites on shared hosting over the years and we'd like to share that knowledge. We'll cover things like:
Out of the box cacheing
Other fun Drupal cacheing modules
3rd party services like CloudFlare
Apache stuff like Mod Deflate
WordCamp Ann Arbor 2014: Site Caching, From Nothing to Everything
The document discusses various techniques for caching websites to improve performance. It covers full page caching plugins like WP Super Cache and W3 Total Cache. It also discusses ways to optimize web servers like Apache and Nginx, speed up PHP parsing, use memcache for generic data storage, implement opcode caching, and do fragment caching. The goal of these caching techniques is to serve cached static content instead of dynamically generating pages each time to improve load times and server efficiency.

2019 StartIT - Boosting your performance with Blackfire
A workshop held in StartIT as part of Catena Media learning sessions.
We aim to dispel the notion that large PHP applications tend to be sluggish, resource-intensive and slow compared to what the likes of Python, Erlang or even Node can do. The issue is not with optimising PHP internals - it's the lack of proper introspection tools and getting them into our every day workflow that counts! In this workshop we will talk about our struggles with whipping PHP Applications into shape, as well as work together on some of the more interesting examples of CPU or IO drain.

Virtualization for Developers
My Virtualization for Developers talk utilizing Vagrant, puppet and VirtualBox to create powerful self-contained development environments.
Migrating to PHP 7
My Migrating to PHP 7 talk given most recently at the International PHP Conference 2016 in Berlin, Germany
Peek at PHP 7
PHP 7 is slated to be released in the Fall of 2015. In this talk I walk you through the highlights of what is new in the next major release.
ZF2 Modules: Events, Services, and of course, modularity
A presentation I gave at php[world], 2015 in Washington, DC on Zend Framework 2 focusing on the EventManager, ServiceManager, and how to build dependent-free modules for your applications
Virtualization for Developers
The document discusses using Vagrant and Puppet to create virtual machine environments for development. Vagrant allows defining and provisioning VMs through a Vagrantfile, while Puppet can further configure the VMs by installing software and configuring settings. Benefits include keeping development environments isolated, easy setup for new developers, and ability to deploy VMs to cloud providers like AWS. The key steps are downloading Vagrant and VirtualBox, defining the Vagrantfile, writing Puppet manifests, and running vagrant up to launch and provision the VM.
Development with Vagrant
A talk I gave at Day Camp for Developers (DC4D) on using Vagrant to create automated virtualized environments for development.
Introduction to Zend Framework 2
The document is an introduction to the Zend Framework 2 (ZF2) architecture. It discusses key ZF2 concepts like modules, the model-view-controller pattern, routes, controllers, and the service manager. Modules are a core concept, with everything including applications being modules. The service manager handles application dependencies and allows for decoupled development. Routes map URLs to controllers and actions. Controllers are executed from dispatched routes and return responses or view models.
10 things not to do at a Startup
John Coggeshall has 18 years of experience in web development and PHP. He discusses several projects that failed due to neglecting technical debt, overcomplicating projects, and ignoring expert advice. Some key lessons are to have expert skills as partners rather than employees, manage expectations, be flexible, have a development process, and keep things simple.
Virtualization for Developers
The rise of virtualization has transformed the server business, but other than that it seems like the developer world has largely been left behind. Regardless of if you are working on one project, or have 20 clients, every developer should know how to use virtualization to create seamless and easy to manage development environments. In this talk we will take a practical approach to using a combination of Puppet, Vagrant, and VirtualBox to create entire development environments in a matter of moments - and even better re-use that template for any project you have in the future in a version-controlled and easily managed manner. Bringing on a new developer for your project? We'll show you how they can get a full-fledged development environment from zero to working in under 10 minutes.
Puppet
My talk given at Confoo, 2011 in Montreal, Quebec on using the Puppet client/server deployment tool for complex web application deployments. This is an introduction talk, and introduces everything you'll need to get started.
Building PHP Powered Android Applications
This is a talk I gave at PHP Quebec 2009 on building Android applications with PHP back-ends. Posted for completeness, the majority of this talk was buried in Android/Java and PHP code.. That said, there are still some useful things in the slides themselves to share.
Ria Applications And PHP
The document discusses building rich internet applications (RIAs) using Adobe Flex and AIR with a PHP/Zend Framework backend. It describes a project to modernize a legacy DOS-based dealer management system (DMS) by creating an internet-based version that provides data sharing and analytics capabilities. Flex and AIR were chosen for the user interface to provide a desktop-like experience, while PHP/Zend Framework handles the backend functionality. Challenges included a lack of server push capabilities and no hardware support in AIR. These issues were addressed through custom data transfer code and a Java server (Merapi) that could communicate with hardware devices.
Beyond the Browser
A brief keynote I gave at PHP Quebec regarding the shift away from the browser for applications and the potential impacts it will have on our development needs as an industry
Ria Development With Flex And PHP
My slides from ZendCon 2008 on Rich Internet Application Development using Zend Framework, PHP, and Adobe Flex.
Enterprise PHP: A Case Study
These are the slides from my ZendCon 2007 talk on a project we did in Professional Services to basically rebuild from scratch InTicketing's (TicketMaster competitor) e-commerce engine using Zend technologies. It was very well received (not even standing room) and well worth a look!
Building Dynamic Web Applications on i5 with PHP
A short web cast I gave with Zend's VP of Business Development Mike Pinette targeted at introducing PHP to those who manage IBM i5 servers
PHP Security Basics
The document provides an introduction to PHP security basics. It discusses identifying principals (the targets of attackers like private data), understanding common attack vectors like SQL injection and cross-site scripting, and employing defense in depth with overlapping security tactics to protect against multiple attack vectors. The presentation emphasizes understanding what information an attacker could derive from an application in order to better protect principal data and functions.
Migrating from PHP 4 to PHP 5
A talk I gave at php|tropics on the potential risks and challenges when migrating an existing PHP version 4 application to PHP 5
Ajax and PHP
A three hour tutorial I gave at PHP Quebec on the challenges, theory, and concepts behind making asynchronous JavaScript calls for Web 2.0 Applications using PHP
John's Top PECL Picks
A presentation I gave at PHP Quebec, 2006 on some of the less known and very powerful PECL extensions available for PHP

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
