A leaky abstraction in software development refers to a design flaw where an abstraction, intended to simplify and hide the underlying complexity of a system, fails to completely do so. But the moment our program needs to represent plato, who did not have a given name, that abstraction. This is what i call a leaky abstraction
Tcp attempts to provide a complete abstraction of an underlying unreliable network, but sometimes, the network leaks through the abstraction and you feel the things that the abstraction can't quite protect you from That might work for a large number of people This is but one example of what i've dubbed the law of leaky abstractions:
A leaky abstraction refers to any implemented abstraction, intended to reduce (or hide) complexity, where the underlying details are not completely hidden or in other words for software it's when you can observe implementation details of a feature via limitations or side effects in the program.
A leaky abstraction is one that doesn't manage to fully encapsulate the details that it's meant to hide Complex ideas can rarely be fully encapsulated Your computer is an abstraction but if you want to play a game that it can't support you are immediately exposed to its limitations Leaky abstractions are not an anti pattern or a code.
C++ string class is another example of leaky abstraction On a string instance s, we can do s + bar but when we do foo + bar we have to recognize that strings are really char* underneath In conclusion, abstractions are good when writing code but we still have to learn what's underneath them. In 2002, joel spolsky introduced the world to the law of leaky abstractions
It's a principle that has resonated with software engineers …
The real art of programming is recognizing abstractions, navigating their leaks, knowing when and how to patch the gaps so don't fear the leak abstraction. Joel spolsky's law of leaky abstractions is more than a software development rule It's a fundamental principle for navigating the complexities of the modern world We explore how this law applies everywhere, from tcp/ip stacks to the legal system and beyond.
However, if you read joel spolsky's now famous blog post about leaky abstractions, you can see that it's not what the term meant at all An alternative name i would suggest for the law is the futility of perfect abstractions, because while ideal, perfect abstractions don. Leaky abstractions if an abstraction doesn't fully encapsulate what it is trying to we call that abstraction leaky. as an example, say we define a person as having a first name and a given name
