Introduction to Design Patterns and SingletonJonathan Simon
This is Class 1 on a 6 week course I taught on Software Design Patterns.
This course provides an introduction into Design Patterns and delves into the Singleton Pattern.
Class based on "Head First Design Patterns."
Step by step description of how to implement a class and how Objects use in a class. You
can use these Concepts in Java, .Net and Php for software or website development.
This presentation was given to the desingers team at MercadoLibre. The outline is working different between HTML4 & HTML5. Understanding the different ways of giving semantics to the content is the goal.
MercadoLibre is every day less requested with the IE7 browser. So in a few months we are going to leave giving support for that specific browser. Now, with a little previous analysis we are able to use the html5shiv tool. I used this slides to explain, share and reflect about how is and works the new HTML5 outline.
This was based on http://www.slideshare.net/hmammana/semantic-markup-creating-outline.
This presentation given for developers at Truelogic Software Solutions is about CSS and layouting. It is explained all the ways to re-position an element in the screen.

JavaScript language plays a very important role in Web 2.0 application development. JavaScript has its own characteristics different than object-oriented languages and it's not easy for developers to understand.
This presentation covers major advanced topics in JavaScript languages, including prototype chain, identifier resolving, "this" keyword, "new" operator, execution context and scope chain and closure. Besides that, it also covers best practices when using JavaScript.
Understanding Object Oriented Javascript - Coffee@DBG JuneDeepu S Nath
You all might have downloaded and edited a lot of javascript. Other than merely changing syntax have you really understood its working or how the code was organised ?
Have you ever thought of how the object oriented way of writing Javascript has been influencing the front end development?
From a language that had helped developers write small validations and similar stuff, today, the object oriented javascript and its frameworks power the world becoming one of the most prominent language of all times.
introduction, The Resolution of Property Names on Objects.
Closure
A "closure" is an expression (typically a function) that can have
free variables together with an environment that binds those
variables (that "closes" the expression)

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).

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

3. Object Oriented JavaScript
JavaScript has one of the most flexible and expressive
object systems available in any popular programming language.
All types of functions, arrays, key/value pairs, and data structures
in general are really objects.
JavaScript handles classical inheritance
with less code than most class-based languages.
Understanding how the prototype works is
an important part of learning the JavaScript language.
4.
5. table of contents
1. functions
2. constructor functions
3. this keyword
4. instances
5. prototype
6. own properties
7. prototype properties
6. functions
1. functions are objects
2. create scope
3. have in mind the most important methods of the functions objects
1. call()
2. apply()
4. the most important property of a function is the prototype property
7. constructor functions
1. it is the pattern that JavaScript uses for native constructor functions
2. the role is to create objects that share certain qualities and behaviours
3. think it as template or cookie cutter for producing pre-defined objects
4. begin with a capital letter to distinguish from regular functions
5. the benefit is they accept parameters, used when creating new objects
6. using the new operator, we want an instance of the constructor function
7. omitting the new operator may not behave as you could expect
8. this keyword
1. this keyword is an object that will be returned by the constructor
2. this object is automatically created by new keyword
3. we can leverage the object via this before the object is actually created
4. it will be an instance of the constructor’s type
5. without new, the value of this is equal to the global object
9. instances
1. the returned object from the constructor function is an instance of that
2. If there are 100 instances, there are 100 copies of the exact same thing
3. there’s no reason that each instance needs to have its own properties
4. it contains a reference to the constructor function used to create it
5. the instanceof operator
1. determine if an object is an instance of a constructor function
2. it will return true any time you ask if an object is an instance of Object
3. only works with complex objects and instances from constructor
functions
10. prototype or Flyweight Pattern
The intent of this pattern is to use sharing
to support a large number of objects
that have part of their internal state in common
where the other part of state can vary.
11. prototype
1. you should care about the prototype property for four reasons
1. it is the mechanism that JavaScript itself uses
2. user-defined constructor functions can use inheritance the same way
native objects do
3. someday you might have to edit or manage someone else’s code
4. you can create efficient object instances that all leverage the same
methods
12. prototype
1. every function has a prototype property used in creation of instances
2. makes it ideal for methods
3. all built-in objects have a prototype that you can change
4. it's important to note that the prototype is "live"
5. it allows to alter properties and methods of existing objects at any time
6. you cannot assign a value to a prototype property from an instance
7. isPrototypeOf() method is used as a prototype of another object
8. augmenting built-in objects is a very powerful technique
9. when overwrite the prototype reset the constructor property
13. prototypal inheritance
It was conceived to allow inheritance chains that mimic the inheritance
patterns found in traditional object-oriented programming languages.
Inheritance is simply one object being given access to another object’s
properties.
This is done by instantiating an instance of the object you want to inherit
from as the value for the prototype property of the function that creates the
object that is doing the inheriting.
