Yes Answering the Call to a Writing MinistryMelanie Rigney
“This is what the Lord, the God of Israel says: ‘Write in a book all the words I have spoken to you …’” (Jeremiah 30:2, NIV) Are answering the call to write?
Confused about writing in Christian/Inspirational vs. Secular? Quick rule of thumb: If Christ’s presence in someone’s life isn’t readily apparent in a work, it’s generally secular. This doesn’t mean it’s anti-Christian. Many Christians excel in the general market. Check out the tips and techniques to get you started.
Ever wanted to create a "direct manipulation" program where you select various tools and manipulate stuff on a workspace? These sorts of applications are quite difficult to build due to the many possible combinations of behavior that is needed. Every tool must know what to do with each type of object. How do we manage this sort of complexity? Well the GOF (gang of four) author John Vlissides documented this pattern in this paper

RESTful APIs are useful when developing a modern web application since they allow for multiple possibilities for collaboration with third-party software as well as multiple types of front-ends, such as mobile apps and HTML5 web applications. The creation of RESTful API’s is facilitated using Laravel 4, a PHP 5.3 Framework that is rapidly growing in popularity. Laravel’s features such as the facade pattern allow for easy-to-read code and expressive ORM statements.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
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.
The Metaverse and AI: how can decision-makers harness the Metaverse for their...Jen Stirrup
The Metaverse is popularized in science fiction, and now it is becoming closer to being a part of our daily lives through the use of social media and shopping companies. How can businesses survive in a world where Artificial Intelligence is becoming the present as well as the future of technology, and how does the Metaverse fit into business strategy when futurist ideas are developing into reality at accelerated rates? How do we do this when our data isn't up to scratch? How can we move towards success with our data so we are set up for the Metaverse when it arrives?
How can you help your company evolve, adapt, and succeed using Artificial Intelligence and the Metaverse to stay ahead of the competition? What are the potential issues, complications, and benefits that these technologies could bring to us and our organizations? In this session, Jen Stirrup will explain how to start thinking about these technologies as an organisation.

2. What is an ORM?
An ORM is the software artefact who maps from relational data base
tables to object/class
This means: maps the tables and columns in a relational database directly
to the object instance and wraps all SQL/DDL functionality in his
methods.
Jorge A. Medina Oliva - Barcelona (http://pybcn.org)Introduction to python ORM SQLAlchemy May. 22 , 2014 2 / 18
3. SQLAlchemy it’s equivalent to...
Hiberante in java (main ideas become from here)
Doctrine in PHP
DataMapper in ruby (this is more close to Active Record pattern)
NHibernate in .Net C#
django ORM in python Web framework
Jorge A. Medina Oliva - Barcelona (http://pybcn.org)Introduction to python ORM SQLAlchemy May. 22 , 2014 3 / 18
4. differences with django orm
There are two very important differences between SQLAlchemy and
Django. SQLAlchemy is a deeply layered system, whereas Django’s ORM
is basically just one layer which is the ORM you see.
1 In SQLAlchemy you have at the very bottom the engine:
Connection pools and basic API differences between different databases
On top of that: the SQL abstraction language,
On top of SQL abstraction: the table definitions with the basic ORM
And on top of ORM you have the declarative ORM which looks very
close to the Django ORM.
2 The other more striking difference however is that SQLAlchemy
follows the “Unit of Work” pattern whereas Django’s ORM follows
something that is very close to the “Active Record” pattern.
Jorge A. Medina Oliva - Barcelona (http://pybcn.org)Introduction to python ORM SQLAlchemy May. 22 , 2014 4 / 18
5. SQLAlchemy Advantages
Great documentation at http://www.sqlalchemy.org
Independent framework
active and stable development
Strong design since beginning
Layered components like Connection pool, ORM, API, SQL,
Aggregates, etc.
We can use any independent component
Implement advanced Hibernate’s ideas.
SQLAlchemy doesn’t override all your columns when you just changed
one on update.
differed column load
Connection pooling

6. SQLAlchemy Disadvantages
Documentation overwhelming
Confuses at the beginning because exist different programming
options.
only integrates in Flask-SQLAlchemy web framework
