Domain Driven Design and Hexagonal Architecture with RailsDeclan Whelan
You know that Domain Driven Design, Hexagonal Architecture, and the Single Responsibility Principle are important but it’s hard to know how to best apply them to Rails applications. Following the path of least-resistance will get you in trouble. In this session you will learn a way out of the “fat model, skinny controller” hell. You will leave with a roadmap to guide your design based on concepts from Domain Driven Design and Hexagonal Architecture.
It contains basic fundamental of class, object, method overloading, constructor, destructor, visibility, acess specifier, Methods, overloading, clonning of objects etc. are covered here.
Kindly look at it and give your comments to improve it as good as possible ways.
It contains different concepts of Object Oriented PHP like cloning of object, Inheritance, function overriding, Final function, Error Handling, Exception Handling, Custom error handling class, Uploading a file to the server with different criteria like file size, file type, file extension etc. are discussed in this presentation.

Functions being first-class citizens in JavaScript offers developers a tremendous amount power and
flexibilty. However, what good is all this power if you don't know how to harness it?
This talk will provide a thorough examination of JavaScript functions. Topics
that will be covered in this talk are:
* Functions are objects
* Execution Context and the Scope Chain
* Closures
* Modifying Context
* The Various Forms of Functions.
Attendees will leave this talk understanding the power of JavaScript functions and the knowledge to apply new
techiques that will make their JavaScript cleaner, leaner and more maintainable.
WCF Data Services (formerly known as "ADO.NET Data Services") is a component of the .NET Framework that enables you to create services that use the Open Data Protocol (OData) to expose and consume data over the Web or intranet by using the semantics of representational state transfer (REST). OData exposes data as resources that are addressable by URIs. Data is accessed and changed by using standard HTTP verbs of GET, PUT, POST, and DELETE. OData uses the entity-relationship conventions of the Entity Data Model to expose resources as sets of entities that are related by associations.
Refactoring can either completely disrupt your project or make you go faster. This presentation will help you to avoid some pitfalls.
It also demonstrates refactorings that you could apply straight away to make your code better.
JavaScript - Chapter 9 - TypeConversion and Regular Expressions WebStackAcademy
Type Conversion:
JavaScript is loosely typed language and most of the time operators automatically convert a value to the right type but there are also cases when we need to explicitly do type conversions.
While JavaScript provides numerous ways to convert data from one type to another but there are two most common data conversions :
Converting Values to String
Converting Values to Numbers
Regular Expressions:
A regular expression is an object that describes a pattern of characters.
The JavaScript RegExp class represents regular expressions, and both String and RegExp define methods that use regular expressions to perform powerful pattern-matching and search-and-replace functions on text.

One of the techniques developed inside the Knative Project is the concept of duck typing control plane resources. This enables a loose coupling not only between Knative and third party extensions, but between the Knative components themselves. Duck typing is broadly applicable to the Kubernetes ecosystem as a way to enable this loose coupling, and we are seeing interest and adoption in projects like Cluster API, Crossplane, and many others. Let's look at some examples and then deep dive to understand how this works and how you might leverage the techniques yourself.
Java9 Beyond Modularity - Java 9 más allá de la modularidadDavid Gómez García
These are the slides I used for my "Java 9 beyond modularity" at several different local meetups and conferences in Spain during 2017
Java 9 is about to reach its public release scheduled for September 2017. If we ask what are the new features that this new version will include, probably the first that comes to our head is modularity.
But java 9 brings with a lot of features beyound Jigsaw, JPMS or modularity. In this talk we will talk about at least 9 other new features that include this new version of Java that are interesting and maybe will end up being more used than the modularity itself for those who embrace the new version.
Those are changes that come to complement and improve even more the set of new tools (like Streams, Optionals, etc...) that Java 8 brought to us.
We'll take a look at small changes in language syntax (such as new ways of using try-with-resources), changes in Collections APIs and Streams, new tools like VarHandles, new APIs such as the Flow API, and As we allow the inclusion of reactive programming with Java.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
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.

3. Introduction
Web applications are really easy to distribute.Web Applications need to adapt
and behave differently under different situations
For a request from Spain the application might want to display messages in
spanish and in english when request is made from New York
The adaptations made by the application may involve more complexity than
simply displaying different versions of text. An application may need to impose
different business rules based on the origin of a particular request.
4. Let’s see what Grails has in
its arsenal for this problem?
5. Localizing Messages
One way of providing this capability is to have a separate version of the
application for each language you want to target. That approach has lots of
problems.
Maintaining all those different versions and trying to keep them all in sync
would be an awful lot of work. A much better idea is to have a single version of
the application that is flexible enough to display messages in various
languages using localized messages.
6. Localizing messages Continued ..
To support localized messages in your Grails application, you should be defining all
user messages in a properties file.
User messages should not be hard-coded in GSP pages, GSP templates, or
anywhere else.
Having messages in a properties file allows you to maintain all of them all in a single
place.
It also lets you take advantage of the localization capabilities provided by Grails.
8. I18n Directory Structure Continued ..
When a Grails app is created, the project includes a number of localized property
files in the grails-app/i18n/ directory
The messages.properties file in the grails-app/i18n/ directory contains default
validation messages in English. These messages are used when validation fails in a
domain class or command object.
In addition to the default messages.properties file, this directory has several other
properties files that contain the same messages in other languages. For example,
“es” is the language code for Spanish, so messages_es.properties contains
validation messages in Spanish.
9. I18n Directory Structure Continued ..
Example of a properties file - application.properties
app.grails.version=2.4.4
app.name=smartly
app.servlet.version=3.0
app.version=0.1
Property files are plain text files, which contain name-value pairs.
11. Retrieving Messages - message Tag
<body>
...
<g:message code="app.smartly.welcome"/>
... </body>
The code attribute tells the message tag which property value should be retrieved.
By default, Grails will decide which version of the property file to use based on the
locale of the current web request.
A simple way to test your Grails application’s localization is to include a request
parameter named lang and assign it a valid language code, such as “es” for
Spanish
12. Using URLMapping
A URL Mapping for Localization
class UrlMappings {
static mappings = {
"/store/$lang"(controller:'store')
// ...
}
}
This mapping will map all requests to a URL such as http://localhost:
8080/smartly/en/ or http://localhost:8080/smartly/es/, where “en” and “es” could be
any valid language code.
14. Using Parameterized Messages
Often a user message may consist of more than simple static text.
The message may need to include some data that is not known until runtime.
Defining a Parameterized Message
# messages.properties
gtunes.purchased.songs=You have purchased ({0}) songs.
15. Continued
java.text.MessageFormat class uses a zero-based index
{0} in the message is a placeholder for the value of the first parameter.
If the message had multiple parameters, they would be represented in the
value of the message with placeholders like {0}, {1}, {2}, and so on.
The message tag supports an optional parameter named args, and if that
parameter is assigned a value, its value will be treated as a list of
parameters that need to be applied to the message.
18. Using messageSource
Grails provides a bean named messageSource that can be injected into any
Grails artefact, including controllers, taglibs, other beans, and so on.
The messageSource bean is an instance of the org.springframework.context.
MessageSource interface
This interface defines three overloaded versions of the getMessage method for
retrieving messages from the source.
19. Using messageSource Continued ..
String getMessage(String code, Object[] args, Locale locale)
String getMessage(String code, Object[] args, String defaultMessage, Locale locale)
String getMessage(MessageSourceResolvable resolvable, Locale locale)
Since the messageSource bean participates in Grails’s dependency autowiring
process, all you need to do to get a reference to the bean is declare a property named
messageSource in your Grails artefact.
20. Using messageSource Continued ..
package com.gtunes
class StoreService {
def messageSource
def someServiceMethod() {
def msg = messageSource.getMessage('gtunes.my.music', null, null)
// ...
}
...
}
Note that the second and third arguments are null. The second argument is an Object
[], which would be used to pass parameters to a parameterized message. The third
argument is a java.util.Locale, which may be specified to retrieve a message for any
Locale other than the default Locale for this request.
21. Using messageSource Continued ..
Example -
class StoreService {
def messageSource
def someServiceMethod() {
def msg = messageSource.getMessage('gtunes.my.music',null,Locale.ITALIAN)
// …
}
...
}
22. Using g.message
From within a Controller or TagLib artefact, a simpler way to retrieve messages
is to invoke the
message GSP tag as a method on the special g namespace variable available
in those artefacts
def index() {
def msg = g.message(code:'gtunes.my.music')
} //All tag libraries are accessible using the very same technique.
24. Summary
Retrieving messages from a property file is a snap in a Grails application. The
message tag is very easy to access and use from GSP pages and GSP
templates. The messageSource bean is easily accessible from wherever the
application may need it. All of these enhancements are built on top of proven
and well-understood Java-platform tools, including java.text. MessageFormat
and org.springframework.context.MessageSource.
