Before you're hired:
1. A binary tree?
2. Currying?
3. Higher-order function?
4. How does event loop work?
5. What is prototype?
6. What is encapsulation?
7. Can you draw an algorithm?

After you're hired:
1. Hey, can you add auth token and login to our app?

"Hey nephew, why doesn't the FB app work. It shows blank white boxes?"
- It can't connect or something? (I stopped using the FB app since 2013.)

"What is this safe mode that appeared on my phone?!"
- I don't know. I don't hack my smartphone that much. Well, I actually do have a customised ROM. But stop! I'm pecking my keyboard most of the time.

"Which of my files should I delete?"
- Am I supposed to know?

"Where did my Microsoft Word Doc1.docx go?"
- It lets you choose the location before you hit save.

"What is 1MB?"
- Search these concepts on Google. (some of us did not have access to the Internet when we learned to do basic computer operations as curious kids.)

"What should I search?"
- ...

"My computer doesn't work.. My phone has a virus. Do you think this PC they are selling me has a good spec? Is this Video Card and RAM good?"
- I'm a programmer. I write code. I think algorithmically and solve programming problems efficiently. I analyse concepts such as abstraction, algorithms, data structures, encapsulation, resource management, security, software engineering, and web development. No, I will not fix your PC.

My last special snowflakes teacher story. This happend last Friday.

Background: we had to do a "little" project in less than 2 weeks (i ranted about that) and got our degree on Friday. I did a perfectly fine meal suggester, with in my opinion one of the best codes i've ever written.

After getting my degree (which is totally fine and qualifies me as IT technician/ "staatlich geprüfte Informationstechnische Assistentin") i asked him what my grade for the project was.
Me: what was my grade for the project again?
Him: i left it at 90%
Me: why exactly? You seemed to be really excited and liked it obviously. And there was no critique from you after my presentation.
Him: yadda yadda. I can't give you more. Yadda yadda be happy i didn't lower your grade.
Me: why would you lower my grade? This doesn't make sense at all. I matched all your criteria. You wanted a program everyone loved, everyone wanted to buy. There you go. I made exactly that.
Him: i can't give you a 1 (equals an A)
Me: why not?
Him: you wrote to much. I didn't want so much (he never specified a maximum). And you used to advanced code. And there were so many lists and ref - methods. The class couldn't benefit from it.
Me: Excuse me!? The only "advanced code" i used was a sqlite library. And i explained what i did with that. What do you mean by "so many lists" and ref-menthodes. In which methodes am i using ref?
Him: I don't know, i just skimmed through the code.
Me, internal: WHAT THE FUCKING HELL!?
Me: so you are telling me, you didn't even read my code fully and think it is too advanced for the class? And because of that you give a 2 (equals a B)?
Him: yes
I just gave him a deathstare and left after that. What the hell. Yes, i used encapsulation - which is something we hadn't done much in class. But the code is still not more advanced because i use more files -.-

My friend after he watched some of the shows I recommend him(silicon valley, Mr robot, etc)
"You're like an encapsulation of all the things wrong with the characters, without the genius"

I was having dinner with two girls, one a project manager and the other some finance reviewer or something like that. We were discussing our line of work and I was talking about how bad quality code affects everybody and the finance reviewer girl goes like (and I quote) "In our company we use polymorphism, inheritance and encapsulation so it's not a big problem. So our database has a parent class and we only use the parent class". I was at a loss for words. I mean, if only more programmers just did that, right?

Is it just me who sees this? JS development in a somewhat more complex setting (like vue-storefront) is just a horrible mess.
I have 10+ experience in java, c# and python, and I've never needed more than a a few hours to get into a new codebase, understanding the overall system, being able to guess where to fix a given problem.
But with JS (and also TS for that matter) I'm at my limits. Most of the files look like they don't do anything. There seems to be no structure, both from a file system point of view, nor from a code point of view.
It start with little things like 300 char long lines including various lambdas, closures and ifs with useless variables names, over overly generic and minified method/function names to inconsistent naming of files, classes and basically everything else.
I used to just set a breakpoint somewhere in my code (or in a compiled dependency) wait this it is being hit and go back and forth to learn how the system state changes.
This seems to be highly limited in JS. I didn't find the one way to just being able to debug, everything that is. There are weird things like transpilers, compiler, minifiers, bablers and what not else. There is an error? Go f... yourself ...
And what do I find as the number one tipp all across the internet? Console.log?? are you kidding me, sure just tell me, your kidding me right?
If I would have to describe the JS world in one word, I would use "inconsistency". It's all just a pain in the ass.

I remember when I switcher from VisualStudio/C# to Eclipse/Java I felt like traveling back in time for about 10 years. Everyting seemd so ... old-schoolish, buggy, weird.
When I now switch from java to JS it makes me feel the same way. It's all so highly unproductive, inconsistent, undeterministic, cobbled together.
For one inconveinience the JS communinity seems to like to build huge shitloads of stuff around it, instead of fixing the obvious. And noone seems to see that.
It's like they are all blinded somehow. Currently I'm also trying to implement a small react app based on react-admin. The simplest things to develop and debug are a nightmare. There is so much boilerplate that to write that most people in the internet just keep copying stuff, without even trying to understand what it actually does.
I've always been a guy that tries to understand what the fuck this code actuall does. And for most of the parts I just thing, that the stuff there is useless or could be done in a way more readable way. But instead, all the devs out there just seem to chose the "copy and fix somehow-ish" way.
I'm all in for component-izing stuff. I like encapsulation, I'm a OOP guy by heart. But what react and similar frameworks do is just insane. It's just not right (for some part).
Especially when you have to remember so much stuff that is just mechanics/boilerplate without having any actual "business logical function".

People always say java is so verbose. I don't think it is, there is so few syntax that it almost reads like a prose story. When I look at JS and TS instead, I'm overwhelmed by all the syntax, almost wondering every second line, what the actual fuck this could mean. The boilerplate/logic ration seems way to off ..

So it really makes me wonder, if all you JS devs out there are just so used to that stuff, that you cannot imagine how it could be done better? I still remember my C# days, but I admin that I just got used to java. So I can somehow understand that all. But JS is just another few levels less deeper.
But maybe I'm just lazy and too old ...

The new mobile app codebase i'm working with, was clearly written by someone who just read a book on generics and encapsulation.

I need to pull out 2 screens into a separate library to have it shared around. The 1 networking request used is wrapped up in a 'WebServiceFactory' and `WebServiceObjectMapper`, used by a `NetworkingManager` which exposes a generic `request` method taking in a `TopLevelResponse` type (Which has imported every model) which uses a factory method to get the real response type.

This is needed by the `Router` which takes a generic `Action` which they've subclassed for each and every use case needing server communication.

Then the networking request function is part of a chain of 4 near identical functions spread across 4 different files, each one doing a tiny bit more than the last and casting everything to a new god damn protocol, because fuck concrete types.

Its not even used in that many places, theres like 6 networking calls. Why are people so god damn fucking stupid and insist on over engineering the shit out of their apps. I'm fed the fuck up with these useless skidmarks.

> Last year wrote a unittest - I was asked to delete it
> no design patterns. Not a single one
> no encapsulation
> fucked up inheritance [I had no idea it was possible at all...]
> generics every-fucking-where
> I could go on...

this month the lead dev was not in and I had to make a new feature. Guess what I did :)

tdd [coverage >90%], a couple of builders, a factory or two, two composites, one decorator, only a few generics - only where really needed. Private fields, not a single @Autowired field [they were fucking my tdd], nicely abstracted integrations, and so on. Everything is writen according to clean code: max 10loc methods, <140col lines, reusable constants and utils, SOLID as a rock, etc.

Due date is next week. Took me 3 weeks to craft it.

Guess who's gonna be piiiiiiiiiiiiisssedd 😁

the best part - I don't even work there, our company was hired for xx hours as helping hands 😁

that's not all. They have like 6 envs and their deployment is all-fucking-manual. Will try to learn how to dockerize that app and deploy it on docker. Gosh I wish I could see his face when he's back 😁

p.S. From ethical point of view, he's the only dev who believes his code is perfect. No other dev in the team agrees. AND he once said: 'it's gonna be my way or no way at all'. So I don't think I did wrong... Did I? :)

Been really busy with things haven’t got around to posting a book in like a week or so..

But I’ll post one today..

This book...

This book, available for free online or you can buy it, written in 1994. But so under appreciated by people for some reason most people never have seen it or know about it. But this is the ONLY book I know of that actually covers this topic.. the only book in existence that specifically goes thru how OOP can be done with C.

NOW hold up before you say just use C++ stop and think for a second.. bear with me.

First off this book is purely for informational purposes and educational use to deepen your understanding of what OOP is actually doing behind the scenes in languages like C++ where keywords exist for these things and you just blindly use them without thinking about under the hood.

This book contains a lot of code and builds you up a complexly library from scratch to make OOP in C... now I don’t take this book literally and this but I have implemented some concepts from this book in projects in the past, and it helps a lot.

Also in my honest opinion If you finish this book, you will be a better C programmer AND c++ programmer, C programming because it teaches you a lot about complex things that you never thought about doing with the language. It proves you can do polymorphism can do inheritance and encapsulation. And it’s not really bloated either.

This books is an awesome book, if you don’t understand C pointers you definitely will after this book.. if you don’t understand OOP in C++ what’s really going on.. you will after this book. After all C++ began as just a preprocessor of C.

Great book for writing reusable, extendable large scale embedded c systems.

Anyway.. rare book of which should not be rare considering it’s free.

Basic OOPS Question -

A unit of computer information that contains data as well as all the procedures or operations is called:
(1) A method.
(2) Encapsulation.
(3) An object.
(4) An OOP
(5) None of these

This question is a bit confusing to me.. what do you guys think? 🙄

Let's call my college colleague Andrew.

Andrew knows that we have a really tight deadline to complete 2 different assignments to deliver in the same weekend for evaluation.

Andrew says that we really knows about coding, although we doesn't understand the most basic principles about OOP (like encapsulation, for example).

Whenever I asked for help, Andrew said that is "going to do some research" and that what I'm asking is "really hard". He then asked every single other group if then could provide him, with some code so he could "understand" what I asked him to do.

Once they said "no" he would come and tell me he really tried but hadn't be able to do it, 2 days after needed it, delaying the whole project.

Don't be like Andrew.

How do you deal with someone like this?

I've got this dev at my workplace that is terrible to work with, he's 2 main reasons why I say this:
1. He has no clue about team work, every piece of code he writes is written as if he is the only person that has to ever touch that
2. He's overtly protective and opinionated on things that make no sense, they're non standard "rules" that he sets and enforces by replacing others code with his own (often times you see quite large PRs and after inspection you realize he rewrote parts of code to follow his style). These "rules" also take up a really long time to follow and would make any actually experienced developer question this guy's knowledge, one example of this is where he repeats the same code over multiple components for "encapsulation reasons" and God forbid you create a global helper of some sort, he'll straight up remove it the next chance he gets. Another example is that all his components or utilities live inside 1 base directory, so you have roughly 300+ components in a /components directory, all with non standard names so you can't tell which is related to which.

I hate working with this person, it's annoying and it also sucks because he's sort of a more "senior" Dev so managers take his side most of the time.

I’m done with people that derail meetings and discussions.

While I want to seek feedback for an Interface that I wrote, these attention seekers decide it’ll be the perfect opportunity to bring up the topic of “how functional programming paradigm facilitates better encapsulation”.

Everyone else follow suit. I try “time checking” and bringing the talk back on track. Never worked.

I’m concluding that meetings are shit and a COLOSSAL WASTE OF TIME.

Correct me if I'm wrong, Python is absolutely built on:
--Data encapsulation
--Dependency Hell
-- ambiguous object types
-- You BETTER hope that package has a function to turn that object into another HOPEFULLY SUPPORTED object (basically even more encapsulation)
--Oops this package doesn't support this other package, so you need to do another 20 lines of conversion
I really don't understand what makes Python so likable?? Am I just being stupid, or does exceptions like "This does not support multiclass" the worst fucking exception i've ever seen? Or "Shape (None,1) not compatible with (None,7)"? I get it that you can fix it if you've seen this issues multiple 100s of times, but for the first time, how the fuck am I supposed to debug this?

Few years ago as a junior android dev with couple years of self taught experience of working in startups I submitted a simple android app assignment for a junior android dev role. Assignment had only like 8 requirements so I followed them to the letter. That didn't end well.

App was simple just 3 screens. Login screen with username and password input fields, login button.

Had to call a login endpoint after login button was clicked, redirecting to home screen, calling items endpoint, displaying a list of items and when an item was clicked passing item data and redirect to item details screen.

Needless to say big swinging dick senior was not impressed. UI was not perfect, I forgot to display a loading animation when fetching data, didnt handle back button properly.

I agreed with some points but other comments were clearly just nitpicking: his preferred variable naming conventions, his opinions on architecture that was not up to his standard (official google arch at the time was not up to his standard).

He also was mad that app wasn't prepared for release to googleplay (another out of the ass requirement). Like I would prepare a 3 screen app for prod release that he will forget ever existed after 20min of his review.

Lots more of nitpicking, encapsulation this encapsulation that, omg now hes shocked that there are a few warnings after the project is built.

Regardless my self confidence was destroyed at that point and after few more negative experiences I dropped android dev alltogether for a couple years and switched to game dev.

After game dev ran its course I went back to android dev and found a supportive place where I could grow.

Looking back, they were actually hiring atleast a mid level for a junior position but I was grilled as a senior. The guy literally didnt wrote any single positive thing in that review about my code even tho my senior peers said my project was decent back then, its just that I didnt handle a few edge cases and that's all.

I looked up the guy in linkedin, turns out hes a uni dropout who posts all books that he red about software dev in his education section of his linkedin profile. Found a bunch of other narcissistic stuff on his profile. Guy was a fucking idiot. Even if I worked under him it would have probably sucked.

Learned some important lessons I guess. Always get a second, 3rd and 4th opinion and dont take criticism too seriously. Always check what kind of person is providing feedback.

I was just asked to correct a bug in a form, so I opened up Visual Studio, loaded the projekt, and opened up the code for the form to start debugging:

3500 lines of code in one form!

Encapsulation and classes are fresh ideas...from 30 or 40 years ago!

Just wondering, fellow devRanters...

Q: What is your favorite programming language, and why?

I'm currently studying Unity, so I'm in love with C#, it helped me understand a lot of concepts like namespaces, encapsulation, constructors, something that I was struggling to grasp with PHP, which I use every single day at work.

"What are the four pillars of OOP?"

Me:(I'm not an OOP guy, but focused on design patterns)

1. Encapsulation
2. Abstraction
3. Polymorphism
4. ??(was it inheritance or composition).

Fuck, Because of the phrase "composition over inheritance". I've been mixing both composition and inheritance at the same time.

Encapsulation

Docker's encapsulation is amazing! I don't have to know anything about networking to get a swarm running with some demo services all talking to each other and central logging and... oh I fucked something up... better read about networking so I know what I broke

My first rant in ages:
Been assigned to a new Laravel project at work and the murthafucking lead dev got no fucking clue how to architect a big laravel app. Lead dev talking trash about encapsulation and every big oop grammar he can find while asking us to come up with an architecture concept for the app.
My annoyance is, the fecking project been in planning for like 7 months and d lead dev keeps saying he is looking for ideas on how we will build the app. Fuck this shit!

When you realize your professor who programs since the 486 era names all variables as such ad "vd_gr" (Validation date grant renewal), doesn't know what encapsulation is and writes his own cryptography algs, which basically replace one letter by another

**Facepalm

**then I still I have to tolerate all the critics for why I dropped college

Shit bathed and stack smashing ass loads of fuck.

I wrote a virtual machine, and just to fuck myself harder, I make the decision of applying some fancy dumbass theories of mine. This translates to a piece of shit modular design that works exactly as intended, but constantly gives me vietnam flashbacks to the horrifying, multiple concurrent instances of my younger mind being incessantly turbo-raped by the dozen object-obsessed pedophiles that I initially studied under.

Now, were they *actual* pedophiles? No, of course not. But I have to make fun of the acronym somehow and that's what came to mind, leaking horse dung all over the walls, floor, curtains and carpets.

Anyway, I feel so smart after this traumatic experience I just have to keep doing it to relive the terror once again. Find me in the corner, laying down in the fetal position, sobbing until the tears build up and drown me in this well of despair, or rather this finely shit painted portrait of a toilet in a lonely and stinking unisex public bathroom stall.

But let me squeeze these fucking tits a little bit harder, because that's my actual day job. That's right. I get PAID for slapping around mammary glands, it's not much but it's an honest living.

So where was I? Ah, yes, absolute degeneration. I'm truly the Max Wright of programming, mostly for smoking crack and having unprotected sex with homeless people, but also for keeping alien life forms in my basement that go out at night to hunt for sweet feline delight.

But as I keep going, I decide I want a language for the machine so I don't have to punch bits by hand all fucking day like an idiot, so alright let's make a small assembler for this shit... oh, right, except it's not small, because gently suckle the bile out the lips of my fucking butthole.

I may redefine a load of shit two months down the line, so I have to make everything perfectly encapsulated and easily fucked with -- which in my licking vomit off the floor of a porn theater travesty of a case means I'm generating half the code and scrambling as hard as I can to glue everything together.

Does it work? Of course it works, I'm Max Wright bitch. I can redefine the ISA all I want, anytime I want without breaking anything because of my pristine crackhead encapsulation. And to credit the scrambled eggs I have for fucking brains, it's not even *that* complex.

The problem is I keep forgetting shit, not how it works, just that it's there. So I forget that I have a virtual machine, and I forget that I have an assembler, and so I spend an entire day trying to figure out how the fuck I'm going to handle a loop inside an unrelated interpreter.

By the time I manage to remind the drooling undead jackass that is this husk that my irredeemably demonic self inhabits, that we can easily solve this by using the tools we've already built, it's so late and we're so tired there's not much we can do. All this time, WASTED.

"Reflective" programming...

In almost every other language:
1. obj.GetType().GetProperties()
or
for k, v in pairs(obj) do something end
or
fieldnames(typeof(obj))
or
Object.entries(obj)

2. Enjoy.

In C++: 💀
1. Use the extern keyword to trick compilers into believing some fake objects of your chosen type actually exist.

2. Use the famous C++ type loophole or structured binding to extract fields from your fake objects.

3. Figure out a way to suppress those annoying compiler warnings that were generated because of your how much of a bad practice your code is.

4. Extract type and field names from strings generated by compiler magic (__PRETTY_FUNCTION__, __FUNCSIG__) or from the extremely new feature std::source_location (people hate you because their Windows XP compilers can't handle your code)

5. Realize your code still does not work for classes that have private or protected fields.

6. Decide it's time to become a language lawyer and make OOPers angry by breaking encapsulation and stealing private fields from their classes using explicit template instantiation

7. Realize your code will never work outside of MSVC, GCC or CLANG and will always be reliant on undefined behaviors.

8. Live forever in doubt and fear that new changes to the compiler magic you abused will one day break your code.

9. SUFFER IN HELL as you start getting 5000 lines worth of template errors after switching to a new compiler.

A sweaty furry sodomizing a dead dog would still be less disgusting than the codebase on which I have to work, some highlights are:
- The same class repeated 40 times with little variations instead of using some decent parametrization
- Inexistent encapsulation and separation of concerns, most changes requires to modify and recompile 2-3 indipendent Maven projects
- Abuse of inheritance which instead of being used to create "is-a" relationship as it should be it's used to reuse some methods of a class in another instead of using Spring dependency injection as we should be

It would be understandable in a 20 years old legacy projects but in something which started 2 months ago it drives me mad, I tried to fight to change it but in the big enterprise to which I'm "body-rented" it's impossible

Allright, so now I have to extend a brand new application, released to LIVE just weeks ago by devs at out client's company. This application is advertised as very well structured, easy to work on, µservices-based masterpiece.

Well either I lack a loooot of xp to understand the "µservices", "easy to work on" and "well structured" parts in this app or I'm really underpaid to deal with all of this...

- part of business logic is implemented in controllers. Good luck reusing it w/o bringing up all the mappings...
- magic numbers every-fucking-where... I tried adding some constants to make it at least a tiny bit more configurable... I was yelled at by the lead dev of the app for this later.
- crud-only subservices (wrapped by facade-like services, but still.. CRUD (sub)services? Then what's a repository for...?). As a result devs didn't have a place where they could write business logic. So business logic is now in: controllers (also responsible for mapping), helpers (also application layer; used by controllers; using services).
- no transactions wrapping several actions, like removing item from CURRENT table first and then recreating it in HISTORY table. No rollback/recovery mechanism in service layers if things go South.
- no clean-code. One can easily find lines (streams) 400+ cols long.
- no encapsulation. Object fields are accessed directly
- Controllers, once get result from Services (i.e. Facade), must have a tree of: if (result instanceof SomeService.SomeSubservice1.Item1) {...} else if (result instanceof SomeService.SomeSubservice2.Item4) {...} etc. to build a proper DTO. IMO this is not a way to make abstraction - application should NOT know services' internals.
- µservices use different tables (hats off for this one!) but their records must have the same IDs. E.g. if I order a burger and coke - there are 2 order items in my order #442. When I make a payment I create an invoice which must have an id #442. And I'm talking about data layer, not service or application (dto)! Shouldn't µservices be loosely coupled and be able to serve independently...? What happens if I reuse InvoiceµService in some other app?

What are your thoughts?

God damn it, if you (libGDX) have default values for public methods then make those constants public. Now I am writing wrapper and I either create my constant with same value as your private one, or do some reflection black magic which will probably break after obfuscation. *sigh* Going with my copy of the constant, not happy about that...

To all self made seniors (and those who got granted this title because it was a morale boost): is it really so difficult to grasp ideas like: Single responsibility? Don't repeat yourself? Encapsulation?

Seriously? Is it difficulty level of some quantum physics or what?

I'm not a fucking genius myself either, but when I see 300-500 LoCs function, accepting 10 parameters, having half of code duplicated in different parts of solution - I really wanna start firing people ON THE SPOT.

P.s.
To all shitty developers advocates - I know that everyone makes mistakes sometimes - I'm talking here about consistent "don't give a shit about code" behaviour.

My visceral hate of Spring.Net burns with the force of a thousand suns.

Almost everything it does is done wrong or solved better by other solutions.

Specifying which classes to instantiate from .xml files? Sure why not, compile type safety (the whole reason for using a static programming language) is obviously overrated and dependency based injection is surely impossible!
And for extra bonus points, now our client code must be aware of the internals of the service classes, and all of their references as well, because, encapsulation? Who cares.

Have you made an typo? Good fucking luck finding out from which of the 100 config files we have floating around...

And, because it has baked in AOP and Transactions its woven into the fabric of the project like a tapewom.

Of course this may just be how our "special snowflake" project uses Spring.

What makes it more painful is that I love good DI tools (ninject, castlewindsor, autofac, there are so many...) and we're stuck with this turd because 7 years ago some java devs couldn't be arsed to learn a new library...

I am just student looking for job, and got this pre interview test:
Develop an Android or iOS app with login and password input field, download button, place for image we prvided.

... reading further:
What we are looking for in the code ?
internal quality:
-consistent formatting of the source code
-clean, robust code without smells
-consistent abstractions and logical overall structure
-no cyclic dependencies
-code organized in meaningful layers
-low coupling and high cohesion
-descriptive and intention-revealing names of packages, classes, methods etc.
-single small functions that do one thing
-truly object-oriented design with proper encapsulation, sticking to DRY and SOLID principles, without procedural anti-patterns
-lots of bonus points for advanced techniques like design patterns, dependency injection, design by contract and especially unit (or even functional or integration) tests

external quality:
-the app should be fully functional, with every state, user input, boundary condition etc. taken care of (although this app is indeed very small, treat it as a part of big production-ready project)
-the app should correctly handle screen orientation changes, device resources and permissions, incoming calls, network connection issues, being pushed to the background, signing deal with the devil :D and other platform intricacies and should recover from these events gracefully
-lowest API level is not defined - use what you think is reasonable in these days
-bonus points if the app interacts with the user in an informative and helpful way
-bonus points for nice looks - use a clean, simple yet effective layout and design

... I mean really ? and they give me like 2 days ?

Am I the only one that doesn't think purely data-oriented programming is a particularly good idea?

I mean we're throwing out all the principles that have been established over the last 20 years of OOP like encapsulation and implementation hiding. And you can say what you want about OOP and yes it's not perfect, but there are things that work quite well. Implementation hiding is a perfect example of something that I don't think I just want to give up.

DOP feels like going back to programming C in the 80's with fully procedural functions and completely open structs.

Am I just going mad?

Question.. architecting a large system. I’ve broken it down to microservices for the DB and rest API / gateway

I want there to be some some processes that run continuously not event driven via rest. Say analytics for example what is the best way todo that? Just another service running on on a server? And said service has its own API? That when the other rest APIs are called could then hop and call the new service?

Or say we had a PDF upload via rest should that service then do the parsing before uploading to DB .. or should the rest api that does the uploading then call another rest api to another service dedicated todo the parsing and uploading to the db?

I think the bigger way to explain the question is the encapsulation between DAL.. data access layer which I have existing.. but then there’s the BLL .. buisness logic layer which I don’t know if it should have its own APIs via own microservices running in the background.

I want to make my own Android app. I have completed Java basics. In Java basics I have completed encapsulation, abstraction, inheritance, polymorphism etc. I have basic knowledge of these all. I cannot switch myself to Android studio because I am not having a good laptop but after one month I will buy a good laptop. So in this one month of time what should I learn which will help me in my Android app development.

every (cl)ass has reference of every other class and people are talking about modularity and encapsulation.#FML

Just received code review from interview technical task. 50 percent of it was because of encapsulation (that 5-8 variables could have been private instead of public). 20 percent was about shit that was expected but missing (error validation, dependency injection). It was missing because it was not specified in app requirements and also noone said that I have to build a production level application for a simple interview here. 10 percent was nitpicking about formatting(I used default intellij formatter) and one ide error that appeared because of project importing. And only 20 percent of feedback was actually constructive and useful. Cool. Also developer said that he was shocked that I made loading animation but didnt call it in my app. However I made it, but if you have fast internet connection it doesnt show up. I mean if you run my app on a phone with gprs connection u will see that damn animation. What Im supposed to do slow down the app so u could see it? But we are building production level app here no? Shit. It feels like he applied double standards to me or something. Half of review nitpicking about useless details and another half about shit that is expected to be in the app but was not even communicated. Also I did not get developers contact so I could ask him what the fck he wanted from me.

What is the utility of using encapsulation when we can access public attributes. What is the reason behind defining private members?

Calling out to all frontend devs:
What's your opinion on CSS in JS (e.g. styled-components)?

I really like the encapsulation and the ease of use but I don't like how it makes debugging more difficult.
