Joomla 3 Component programmeren met RAD - Joomladagen 2014Peter Martin
Het Rapid Application Development (RAD) framework is een nieuw feature in Joomla 3.2.
Een Joomla component is een PHP/MySQL webapplicatie die gebruik maakt van Joomla's framework. In plaats van zelf een database connectie op te hoeven bouwen, kun je Joomla's database object aanspreken. Ook de vormgeving via templates, toegangsniveaus, opbouw van formulieren (JForms) kun je via Joomla's framework laten afhandelen. Dit scheelt veel werk en ontwikkeltijd. Toch kan het nog sneller!
De meeste Joomla componenten bevatten dezelfde functionaliteit:
In de front-end worden lijsten met gegevens uit de database getoond, met een hyperlink naar een pagina met detailweergave.
In de back-end worden vaak lijsten met gegevens uit de database getoond, met een hyperlink naar een formulier waarmee je de gegevens kunt wijzigen en opslaan.
Door gebruik van het Rapid Application Development framework (dat is gebaseerd op FOF (Framework On Framework) kun je die veelvoorkomende functionaliteit met veel minder regels code programmeren.
In deze presentatie laat Peter zien hoe je met RAD een eenvoudig Joomla component kunt bouwen om locaties & categorien te beheren en aan bezoekers (in combinatie met Google Maps) te tonen.
Component beschikbaar op: https://github.com/pe7er/db8locate
Joomla bestaat dit jaar (2015) 10 jaar en is in de loop der jaren enorm verbeterd.
Deze presentatie toont de geschiedenis & vooruitgang van Joomla aan de hand van Mambo, Joomla 1.0, Joomla 1.5, Joomla 1.6/1.7/2.5 en Joomla 3.x.
8 Most Common Joomla! Hacks and How to Avoid ThemDaniel Kanchev
On 23.03.2013 I visited The Netherlands to give the keynote speak about Joomla! web security. I talked about the most common 8 ways a Joomla! website can get hacked. So you should check the presentation if you are a Joomla! hacker that knows less than 8 ways :) It will be useful for you. However, if you are a Joomla user that doesn’t know anything about how to hack a Joomla!, or even worse, how to protect your Joomla! from being hacked, you should definitely check the slides! Because there is a way to protect yourself from each of the common Joomla hacks that I revealed them in the presentation.
I went through the following scenarios and what should be done to prevent each of them:
- Hacked through outdated Joomla!/extensions/themes.
- Hacked through a vulnerable extensions/themes, that is not outdated
- Hacked with the help of stolen/weak login details
- Hacked through outdated/vulnerable server software - Apache, PHP, MySQL.
- Hacked through incorrectly configured web server
- A completely healthy site hacked through another vulnerable Joomla that is hosted on the same server
- Hacked because of incorrect Joomla permissions
- Hacked through malware on local PC which allows attackers to access a healthy site
It is extremely common that parts of pages within a Joomla! website are replicated across several views, or even across several extensions. So what does Joomla! contain that could potentially make our lives easier to manage these repeating entities?
JLayouts enters the room...
Joomla's superb JLayout structure was added to Joomla! v3 to help solve this very problem. Having the ability to use different layout's and associated data across views and extensions is such an awesome addition to Joomla!, but have you used it?
Philip will be explaining JLayouts, what it is, how it works & where you could possibly be missing a trick in your front-end development of Joomla! websites.
How to create a joomla component from scratchTim Plummer
In this presentation, Tim Plummer shows you how you can create your own Joomla component by forking Hello World, then adding some improvements to make it more like a typical third party Joomla extension. Files and code used in this presentation will be available for download.

Developing a Joomla 3.x Component using RAD FOF- Part 2: Front-end + demo - J...Peter Martin
One of the new feature since Joomla 3.2 is Rapid Application Development (RAD) framework.
A Joomla component is a PHP/MySQL web application that uses Joomla's framework. You can build your components on Joomla's framework and Joomla will take care of the database connection, the design (using templates), access levels, forms (JForms), etc. Using Joomla's framework saves you a lot of work and development time. However, it can be even faster!
Most Joomla components include the same functionality: In the front-end a list of records from the database hyperlinked to pages with details of each record individually. In the back-end the component list records from the database, with a link to a form where you can change the data and save.
Using the Rapid Application Development Framework (also known as FOF (Framework On Framework)) allows you to develop a component with common functionality with far fewer lines of code.
In this presentation, Peter shows how you can use Joomla's RAD to build a simple Joomla component to manage locations and categories and present those on the front-end to visitors on a Google Map.
Contents:
* Programming a simple front-end component using FOF
* Demo with programming, github & local web environment
A Successful Magento Project From Design to DeploymentJoshua Warren
Magento is a complex open source eCommerce platform. It’s open source nature and welcoming community means anyone can pick it up, learn it and launch it. After working on over 300 different Magento sites in the past 6 years, however, I’ve learned that many of the misconceptions about Magento - it’s slow, hard to work with, buggy or unstable come from projects that were built by first-timers who weren’t aware of Magento best practices. In this tutorial, I walk you through the entire process of creating, testing and deploying a high-performing, fast Magento-based eCommerce website.
"Paragraphs are more powerful than you can expect" from Vasily Jaremchuk for ...DrupalCamp Kyiv
Paragraphs is a next step in the evolution of content management tools. The main goal of paragraph approach to make things cleaner to content managers. End-users can now choose on-the-fly between predefined Paragraph Types. We can encapsulate any Drupal functionality into Paragraph Entity, anything you want from a simple text or image to a complex and configurable slideshow, views, contact form or any other feature that exists in Drupal separately.
The presentation will not include complex information for the developers. I’ll cover only some basic ideas in Paragraphs module architecture. After that I’ll mention the most popular and outstanding modules that extend paragraphs functionality (Bootstrap Paragraphs, Paragraphs Edit, Classy paragraphs, Geysir etc.).
There will be several demos and ideas how we can use paragraphs approach.

Techgig Webinar: Joomla Introduction and Module Development June 2012Vishwash Gaur
As you gain experience with procedural coding in PHP, you notice that there are tasks which are performed in a routine fashion and a lot of code which can be simply reused. What if you can save your time on these points using some of the existing PHP development frameworks and/or content management systems which allows MVC architecture and object oriented programming concepts to follow at ease for you?
In this beginner webinar on the topic, I would cover a quick introduction of content management system with focus on PHP based content management system “Joomla”. Joomla is considered as dynamic portal engine and content management system, and allows you to develop variety of systems from website, ecommerce store to a complex social network with the help of pre-built features i.e. caching, content management, web services, templates, and more.
The real power of Joomla lies in the scalability which can be achieved with the use of custom extensions which include templates, language files, plugins, modules and components. This webinar would further cover quick hands on workshop to download and setup Joomla on a demo server, and developing a simple module and component for Joomla version 2.5.
This webinar covers:
What is the basic database structure difference between Joomla 1.5 and Joomla 2.5 versions?
I was able to create and load modules easily in Joomla 1.5 but I can't do the same in Joomla 2.5?
Are too many modules a problem for the Joomla site?
Does the extension be compulsory an open source code?
Do I really need to switch to Joomla 2.5 from Joomla 1.5 and why?
How can I get more information on Joomla extension development?
Can I use Jquery framework in the extension development while Joomla uses MooTools JS framework?

10 tips to improve the usability of Joomla - Joomla World Conference 2014Sander Potjer
Joomla is very flexible and has many possibilities. A disadvantage is that working with Joomla can seem complex because of all the settings and navigation choices. For a Joomla specialist this is usually not an issue, but for many end users it can be a stumbling block.

Internet of Things - Linux Usergroup NijmegenPeter Martin
A network is formed by connecting some computers. Connecting networks of connected computers to other networks, in combination with an (Internet) protocol, forms the Internet.
What happens if you have other devices to link this network of networks? Peter tells something about the Internet of Things (IoT), Web services, and how a sandwich (cheese, pesto and salad) inspired him to develop a "presence indicator" for his co-work.
Over the past 10 years Joomla! CMS has improved considerably. This presentation shows the history and progress of Joomla CMS.
This year, 2015, Joomla is 10 years old. Over the past 10 years Joomla CMS has improved considerably. At Joomladay France 2015 in Nice, Peter Martin spoke about the history of Joomla and progress of the CMS on the basis of different versions: Mambo, Joomla 1.0, Joomla 1.5, Joomla 2.5 to Joomla 3.x.
De Linux command line is een zeer krachtig stuk gereedschap. De meerderheid van de webservers draait op Linux/Unix. Sommige hosting bedrijven bieden SSH toegang aan tot hun hosting omgeving. Via SSH kun je dan inloggen en de Linux Command Line gebruiken.
In deze presentatie toont Peter enkele tijdsbesparende Command Line commando's die je kunt gebruiken bij jouw Joomla websites:
Enkele SSH command line commando's;
Analyseren en ongedaan maken van een gehackte website;
Een backup maken van een website;
Ongebruikte bestanden vinden;
Het opzetten van een test omgeving.

Music Trackers - Linux Usergroup Nijmegen 2014Peter Martin
Muziek is tegenwoordig vooral beschikbaar in MP3 formaat. In de jaren '80 & '90 was dat anders: MP3 was nog niet beschikbaar en computers hadden onvoldoende geheugen, opslag en netwerk capiciteit.
In deze presentatie vertelt over oude muziek formaten en laat zien hoe hij recentelijk "oude" muziek bestanden (Commodore Amiga tracker files: MOD, IT & XM) op Linux afgespeeld kreeg.
linux-commandline-magic-Joomla-World-Conference-2014Peter Martin
The Linux command line is a powerful tool. The majority of webservers run on Linux/Unix. Some hosting companies offer SSH access to their hosting environment. Via SSH you can login and use the Linux command line.
In this presentation, Peter will show you some time-saving command line commands that you can use for certain tasks on your Joomla websites:
some basic SSH command line commands
Analyzing & recovering a hacked website
Backup a website or move it to another server

Developing a Joomla 3.x Component using RAD/FOF - Joomladay UK 2014Peter Martin
One of the new feature since Joomla 3.2 is Rapid Application Development (RAD) framework.
A Joomla component is a PHP/MySQL web application that uses Joomla's framework. You can build your components on Joomla's framework and Joomla will take care of the database connection, the design (using templates), access levels, forms (JForms), etc. Using Joomla's framework saves you a lot of work and development time. However, it can be even faster!
Most Joomla components include the same functionality: In the front-end a list of records from the database hyperlinked to pages with details of each record individually. In the back-end the component list records from the database, with a link to a form where you can change the data and save.
Using the Rapid Application Development Framework (also known as FOF (Framework On Framework)) allows you to develop a component with common functionality with far fewer lines of code.
In this presentation, Peter shows how you can use Joomla's RAD to build a simple Joomla component to manage locations and categories and present those on the front-end to visitors on a Google Map.
Joomla Bugs, Patches & Fun - Joomladagen 2014Peter Martin
Alle software bevat kleine fouten ("bugs"). Joomla ook. Om die fouten te verhelpen worden verbeteringen ("patches") gemaakt en uitgebracht. Voordat die verbeteringen in de Joomla broncode terecht komen, dienen ze getest te worden. Het in teamverband testen van bugs en patches kan erg leuk ("fun") zijn. Je hebt daarvoor geen programmeerkennis nodig!
Iedereen met een beetje Joomla ervaring kan helpen met het testen van bugs en patches!
In deze sessie verteld Peter Martin hoe hij enthousiast werd over Bugs, Patches & Fun, hoe het proces van software fouten in Joomla oplossen werkt. En hoe jij zonder programmeerkennis kunt helpen om de Joomla broncode te verbeteren.
Joomla on Raspberry Pi using Nginx - Nederlandse Linux Gebruikers Group novem...Peter Martin
De Raspberry Pi (RPi) is een zeer kleine en zuinige (3,5 watt) mini Linux-computer op basis van een ARM-processor. Oorspronkelijk werd de single board computer ontwikkeld voor educatieve doeleinden. De verwachting om in het 1e jaar 10.000 apparaten te verkopen was niet gegrond: ze verkochten 1 miljoen! Waarschijnlijk door zijn veelzijdigheid en lage prijs ($ 35) is de RPi uitgegroeid tot een enorm succes...
Aangesloten op een moderne televisie functioneert de Raspberry Pi als een mini-computer, en op een netwerk als een (web)server. En dat is waar je Joomla kunt inzetten...
In deze presentatie, gegeven op zaterdag 23 november 2013 op de landelijke bijeenkomst van de Nederlandse Linux Gebruikers Groep (NLLGG), laat Peter zien hoe je de RPi als webserver voor Joomla inzet. Hoe je de via de command-line installeert: Raspbian (Debian Linux geoptimaliseerd voor RPi), Nginx (= zeer snel alternatief voor een Apache webserver), PHP, MySQL, phpMyAdmin en, natuurlijk, Joomla.
Tenslotte toont Peter hoe je voor dergelijke websites de security & prestaties kunt verbeteren. En tenslotte hoe je Wifi & Webcam kunt aansluiten & GPIO kunt gebruiken voor aansturing van LEDs.
Configuring Joomla JCE editor from usability point of viewPeter Martin
JCE editor for Joomla is a very popular WYSIWYG editor. However most people just install + use it, and don't put any work in configuring this extension.
This presentation is about configuring Joomla JCE editor from usability point of view:
what should you change in the configuration to work easier with this editor? and what should you remove so that your clients don't mess up the layout of the site?
The Joomla community is HUGE, there are forums, JUGS (Joomla User Groups) blog sites, template clubs, freelance systems, JED (Joomla Extension Directory) and there are hundred of thousands (maybe millions) of people across the globe within this community.
This session will explain how the community works, how to get advice, where to find labour/services and how to find extensions to build up your website. And how to get involved in the Joomla! community.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
