Prestructors

Making constructors pre-process the arguments before encapsulating them seems to be bad practice. However, very often it���s necessary to do exactly that: perform some manipulationswith the objects provided as arguments and only then assignthem to the attributes of the constructed object. For this purposeI suggest using prestructors, which could be methods or stand-aloneobjects.

Dataization

There are three things in EOLANG (and the ����-calculus which webased it on): data, atoms, and objects. There is a dataizationfunction, which puts all three together in order to make an EOprogram alive. Here is how it works together with Java,for example.

Greed-Based Planning

You have an objective, a budget, and a team. You area manager and you want the project to be done. You get your team togetherin a meeting roomto discuss the plan. You tell them what needs tobe done and ask them how fast they can do it. Then, you do the motivational danceand beg ask them to commit. They nod and go backto their cubicles. Of course, after a fewmonths of ���hard work��� all the milestones are missed and you get back to the planningmeeting. And, yes, you pay their salariesan...

Put a Number on Your Boss���s Emotions

You got into a company that believes in
democratic
values, doesn���t measure
performance, doesn���t judge, doesn���t
control, doesn���t force, and
doesn���t blame; however, at the end of the year they tell you that
your performance was not as high as expected. Why?
���Just work better, my friend, we count on you!���
Bad luck, you are in a teal self-managing organization. They���ve already
killed the management, but still didn���t dare to kill the managers.
They don���t know how to measure, but s...

Self-Managing vs. Manager-Free Organizations

We are in trouble. On the one hand, most managers are weak and incompetent.
Their mistakes destroy our motivation,
decrease productivity, and lead to business failures.
As a result, many of us believe that managers are evil.
On the other hand, there is a new idea that self-managing organizations are
the future. Its proponents are trying to convince us that chaos is
better than management mistakes. They want us to believe that subordination,
hierarchy, control,
and order are new bad words to be p...

Abstract Objects

How do you create objects in your object-oriented language?
Let���s take something classic, like C , Java, or C#. First you define
a class, and then you make an instance of it. The first step is known
as abstraction,
and the second one as
instantiation.
A similar pair of operations
exist in functional programming: declaring a function is
abstraction,
while calling it with specific arguments is
application.
The question is:
why does OOP need classes and objects,
while FP survives with just funct...

Objects Without Methods

What do you think an object is in OOP? No matter what language you are
programming with, you will most probably agree with Bruce Eckel,
the author of Thinking in Java, who said that ���each object has a state
and operations that you can ask it to perform,��� or
Benjamin Evans, the author of Java in a Nutshell, who claimed that it is
���a collection of data fields that hold values and methods that operate on those values.���
However, hold on��� What if I told you that an object may have no ���ope...
