The document discusses Zend Framework forms, subforms, display groups, and decorators. It explains that Zend Framework provides object-oriented interfaces for building forms, validating input, and grouping form elements. Decorators handle the markup of forms and implement the decorator design pattern. The document demonstrates how developers can create form elements and add validators, while web integrators can style forms by adding decorators to control rendering.
ZF2 Modules: Events, Services, and of course, modularityJohn Coggeshall
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
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.

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.
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.
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.
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.
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.
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.
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
The document provides tips on common scalability mistakes made when designing web applications and strategies to avoid them. It discusses the importance of considering scalability from the beginning, avoiding blocking calls, caching frequently accessed data, optimizing database and file system usage, and using tools like profilers to identify bottlenecks. The key is designing applications that can scale both up and down based on current needs through a proactive, process-oriented approach.
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!
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.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.
