Connect to Active Directory using DDC SDK

In this post, I will cover a new Open Source Java SDK designed to simplify communication with Active Directory for small, medium and large projects.
DDC (Domain Directory Controller) is an SDK designed to simplify AD interaction for small, medium and large projects. DDC is a portable Java library provided with a friendly API, allowing you to quickly compose simple or complicated queries against AD's endpoints without any previous LDAP knowledge.

I had the pleasure to develop this SDK along with my colleges at Imperva. Now Imperva decided to make it available publicly as an Open Source project. The article was published by officially Imperva, you can find the full article here.

Method Breakpoints are Evil

Some IDEs expose an option to set "Method Breakpoints", it turns out that "Method Breakpoints" might tremendously decrease debugger's performance. In this article, I explain what are "Method Breakpoints" and the reasons they impact performance so badly. To better understand this subject I will cover how Debuggers works under the hoods and how Breakpoints and Method Breakpoints are implemented internally. Java Platform Debugger Architecture JDPA is an architecture designed for enabling communication between debuggers and debugees. The architecture consists of three APIs: JVM Tool Interface (JVM TI) - A native interface which defines the services a VM must provide for debugging purposes Java Debug Wire Protocol (JWDP) - A textual API which defines the communication's protocol between debugee and debuggerJava Debug Interface (JDI) - Defines a high-level Java API designed to facilitate the interaction between debugge and debuggers. Internally J…

Closures in C# vs JavaScript -
Same But Different

Closure in a Nutshell Closures are a Software phenomenon which exist in several languages, in which methods declared inside other methods (nested methods), capture variables declared inside the outer methods. This behavior makes captured variables available even after the outer method's scope has vanished.

The following pseudo-code demonstrates the simplest sample:
Main() //* Program starts from here { Closures(); } AgeCalculator() { int myAge = 30; return() => { //* Returns the correct answer although AgeCalculator method Scope should have ordinarily disappear return myAge++; }; } Closures() { Func ageCalculator = AgeCalculator(); //* At this point AgeCalculator scopeid cleared, but the captured values keeps to live Log(ageCalculator()); //* Result: 30 Log(ageCalculator()); //* Result: 31 } JavaScript and C# are two languages that support…

The GoF Hot Spots - Factory Method vs Abstract Factory

As part of my "GoF Design Patterns - The Hot Spots" posts series, this post is focused on two Creational Design Patterns: Factory Method and Abstract Factory.

We will dig into the original GoF Design Patterns (aka: DP) description trying to figure out the real Hot Spots (aka: specific particular parts that differentiating them from each other) of these two DPs and the relationship between them.

In order to maximize the clarity of this article, I used two conventions:
Phrases inside [square brackets] are meant to help understanding GoF definitionsItalic sentences are GoF's book citationsFactory Method GoF Definition:" [1] Define an interface for creating an object, [2] but let subclasses decide which class to instantiate. Factory Method lets a class defer instantiation to subclasses."
GoF Description & Hot Pots: "Consider a framework for applications that can present [handle] multiple documents to the user. Two key abstractions in this framework are t…
