From Layers to Microunits

The evolution of “Code Cohesion” and “Separation of Concerns”

The software industry has recognized the values of “Separation of Concerns” and “Code Cohesion” for more than two decades. Many articles, books and software-thinkers have contributed methodologies to implement these important values.

In this short article I’d like to compare the conservative “Layers” solution with a new approach, which I call “Microunits”, that can open new ways of solving software design challenges.

GetHashCode Hands-On Session

The following is a hands-on post meant to demonstrate how GetHashCode() and Equals() methods are used by .NET Framework under the hood. For the sake of simplicity I will refer to the popular hashed-base Dictionary type, although any other hash based structure will follow a similar behavior, if not the same one. After understanding this post you should be able to spot potential problematic behaviors and resolve them, prevent creation of unreachable items in dictionaries and improve CRUD actions performance on hash based structures. The Theory GetHashCode() is used to create a unique integer identifier for objects/structs. The hashcode can be used for two purposes: Programmatically, by developers, to distinguish objects/structs form each other (NOTE: Not recommended when the default .NET implementation is used, as it's not guaranteed to preserve the same hash between .NET versions and platforms) Internally, by .NET Framework, when using the object/struct as a key in a has

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 suppo

Design API for Multiple Different Clients

Today I want to talk about common design challenges related to architecture of robust APIs, designed to be consumed by multiple clients with different needs. Our use case is the following: We need to build a N-Tier Web REST/SOAP API that is supposed to read/write data from a DB, perform some processing on that data and expose those methods to our API consumers. In addition we have multiple different API clients each with different needs, meaning we can't just expose a rigid set of functions with a defined group of DTOs (Data Transfer Objects). DTO vs POCO Before start diving I want to explain shortly the difference between these two controversial concepts. DTO Objects that are designed to transfer data between edges (i.e. between processes, functions, server & clients etc'). Typically DTOs will contain only simple properties with no behavior. POCO Objects that are designed to reflect the internal business data model. For example if you have an eCommerce platform
