Where do I start. OOP is not a discipline, it's a paradigm, a mode of thinking about how programming ought to be.

OOP is not primarily about data structures. Not at all. An object is mostly an abstract interface. It might have some data, or it might not. Many OOP practices encourage creating objects that only hold references to other objects and no concrete data at all.

The problem with programming is that computers can only ever move data around and perform some arithmetic operations on them. That's really all they do. Everything else is built on top of that.

Display, audio, and networking at just I/O operations, and I/O to the CPU just looks like reading/writing to and from memory.

There are levels of abstractions, and often times it's beneficial to isolate lower level concerns from higher level concerns.

You can do that just fine with good old procedures.

Sometimes, it's beneficial to have "abstract" objects that could potentially have many different implementations. A file system is the thing that comes to mind most of the time. I can read/write to files without worrying about the underlying file system. That's a good thing.

Not everything is a file system though! Not everything needs to be abstracted and hidden.

The criticism against OOP is usually around the level of granularity.

Within your own code base, you want to know how everything works. You don't want to _hide_ things from yourself.

It might be useful to limit the scope of visibility for some fields, but it's always on an "it depends" basis.

OOP wants you to make strong boundary modules on very small scales, and it comes with absolute rules to help enforce that, like always making everything private by default, and always dealing with abstract objects instead of concrete data and procedures.

When the QT below says that OO is a discipline, they mean that following the OO heuristics is always the right thing to do and it's better to just always do it and get used to doing it, and you don't get to argue about it, just like you always fasten your seat belt, always take a daily shower, always brush your teeth before bed, always go to the gym on schedule, always follow the correct diet. Don't second guess yourself every other step. Just do the right things and you will get the good results.

The problem of course is that you do not get the good results from following the OO rules because they are wrong when applied as such.

Some things can be useful all the time and you should do them even if they bother you a little bit, like fastening your seat belt.

Some things are useful some of the time but not other times, like taking the highway vs the regular road, riding the train vs calling a taxi.

The answer is always "it depends".

This is not to say that there are no heuristics.

There are, but not everyone agrees on them.

Different groups of programmers have different heuristics. Some of them overlap, some of them don't.

Some of my heuristics that I found to be immensely helpful in making programs easier to understand and reason about:

- Prefer regular data and procedures
- Prefer languages where structs have value semantics (as opposed to reference semantics)
- Zero value initialization by default

Everything else is "it depends".

How big should the file be? It depends.

How long should a function be? It depends.

How big should a module be? It depends.

Le sommelier du roi marchait calmement au milieu des bouteilles en cherchant le cru adapté aux grandes occasions. La cosmoculture était un art délicat, et en ce jour de nouveau commencement, il fallait déboucher un monde digne de la cour fantasque des méta-dieux.

La navigation téléastrale avait marqué le début de l'ère interstellaire. Porté par le courant des prières astropathiques des dévots restés sur Terre, le vaisseau avançait vers la ceinture d'Orion. Son capitaine, quant à lui, priait pour que leur foi jamais ne tarisse.

Saviez-vous qu'un jour, un pays a réellement mis fin au capitalisme ?
Un lieu sans argent, sans propriété, sans inégalités, basé sur une saine agriculture vivrière… où le collectif subvenait au besoins de la communauté.
Plongée au coeur des seventies, au Cambodge.

Voilà le pire. Pas seulement les mesures concrètes que prendrait Bardella à Matignon : si d'aventure ils l'emportaient, nous les combattrons à l'Assemblée. Mais les forces obscures, violentes, racistes que cela va libérer dans le pays, les haineux qui se sentiront autorisés. Soutien à la victime dans l'épreuve.

Land doesn't vote, people do! French edition. 🗳️

Each municipality was transformed into a dot, with the area of the dot proportional to the number of voters 👉 a more accurate representation of voting patterns.
Nonetheless, right-wing support 🟤 remains concerning.

Trans girl uses the boy’s restroom. Like “shes’s supposed to” and her jaw gets broken.

This is the world transphobes want trans people to live in.

This is so funny. Gotta love the replies. Confused bigots struggling with their own inconsistencies is such a mesmerizing sight.
