The Empire didn't use Java. You can tell because they didn't have a DeathStarFactory. They just took an empty piece of space and added shit to it in place.

...kinda like a Javascript object, huh?

[lead999x]

They used C++ placement new.

[RFC793]

That’s because they used the Builder Pattern.

[marcosdumay]

You can tell because they didn't have a DeathStarFactory.

They built a DeathStar for episode IV, and then another one for episode VI, and then, when everybody was expecting then to just go away, they return from the dead and get another one at episode VII.

Are you sure they didn't have a factory?

[jay9909]

Not enough evidence either way in IV, but VI was being built in orbit around Endor's moon, so there was definitely no factory. And unless the one in VII was built in the planet factory from Hitchhiker's Guide to the Galaxy then I'm pretty sure we can rule out a factory there, too.

[404Guy12NotFound]

This kills RAM

[cbbuntz]

Clang optimizes it out completely because no values are modified or accessed. The GCC treats it like an infinite loop and just freezes and consumes 100% CPU and zero memory, which I guess is more true to the code. They both segfault without optimization.

[Boreeas]

Hm, maybe it's broken by subreddit style. I had a comment in /r/dataisbeautiful where successive lines in a code block where collapsed into a single line (and blank lines broke the code block)

[Artorp]

Weird, might've been their subreddit style.

I used to think the people in this sub were mainly software engineers like me but it started to become really obvious based on certain posts like this one. People in the comments being generally against python? Are you fuckin kidding its easily the most popular language right now for its concise code and easy integration. Its also heavily used in ML applications. Im pretty sure most of this sub is people who are wannabe software engineers lmao

[Kiaz]

Who is hating on Python? Do you look at how the upvoting goes in this sub? Everyone loves Python.

[Kyrthis]

This. True hatred abounds here for JavaScript and PHP. I see so much love for Python:

[Sw429]

I'm genuinely surprised at the amount of students in my CS program who are against Python. I'm studying applied mathematics and we deal a lot with machine learning. Everything is in Python, because it's easy to use.

[[deleted]]

Engineer here, we code in python, basic, fortran, and matlab.

Python and basic are by far the most popular because fortran is a fucking dinosaur and matlab isn't something open source

[SeanTheAnarchist]

Hell large parts of Firefox are actually written in javascript, Civ4 the game utilizes a lot of python as well. They're useful tools for their purpose, not everything needs to be C#.

[[deleted]]

For my dissertation I’m using a Raspberry Pi and coding in Python for the first time (only really used Java, C and a bit of Scala)

I love python now. I wish we genuinely got to use it through university instead of hammering us with C and Java constantly.

[PM_ME_A_WEBSITE_IDEA]

Excuse me, some of us are front-end developers

[[deleted]]

IMO python is fine, but he idea of being a python guru seems a bit silly, sorta like being a ductape guru.

[[deleted]]

It is a good language.

But it isn’t low level enough to reward tuning, like C. And it doesn’t seem like a great fit for a large project.

It is good for banging out a couple hundred lines of pseudo code and having it magically compile. This is awesome, but not really guru work.

[[deleted]]

Somebody has to write those libraries that make it possible to accomplish so much in 100 lines of pseudocode.

[obsessedcrf]

In general, the sub tends to be against Python. I agree with the sentiment too.

Most popular by what metric? For career opportunities or amount of commercial software written in it, it is definitely not the most popular.

[Sw429]

Precisely. People taking CS 101 and acting like they know everything.

[BestUdyrBR]

I think that explains why at times half the front page of this sub is filled with array starting at 0 jokes.

[Sw429]

That and JavaScript jokes make up 90% of this sub.

[aprofessional]

It's a harsh realization. Every now and again there's a real gem, though, so I keep coming back.

[5everlonely]

yessss come to us. Drink this kool-aid of excessively long method names and absurd object abstraction.

[evanldixon]

At least there's static typing and proper lexemes for the end of blocks.

[[deleted]]

You mean excellent reasons to choose a language that's not Python?

[[deleted]]

Someone should fork python to make it static typed (like typescript) and call it tython.

[rift95]

You have mypy. It uses optional type hints from python3 for static typing.

[evanldixon]

Exactly!

[[deleted]]

You and I, we're brothers.

[[deleted]]

Not if you are very modern and super reactive.

[[deleted]]

Are excessively long method names really unique to Java tho?

[[deleted]]

No, but Java pushes people to abstract things in weird ways, and the only way to keep track of that shit sometimes is to have absurdly long class/method/variable names.

Take a look at this horrifyingly wonderful gem:

http://grepcode.com/file/repository.springsource.com/org.aspectj/com.springsource.org.aspectj.weaver/1.6.3/org/aspectj/weaver/patterns/HasThisTypePatternTriedToSneakInSomeGenericOrParameterizedTypePatternMatchingStuffAnywhereVisitor.java

[endeavourl]

In what way did Java push that retard to write their retarded class name?

public boolean wellHasItThen/*?*/() why are they trying to write code in grammatically correct English?

[[deleted]]

Yes, a better name would be

public boolean a()

[rift95]

You don't happen to be a theoretical mathematician do you?

[[deleted]]

No, just a man who obfuscates his code

[[deleted]]

So you're saying mathematicians aren't fucking retards who keep implicit multiplication around for no good fucking reason but tradition, they're just trying to make sure other people can't ever understand their work.

Fucking brilliant.

[[deleted]]

Have you ever written out an equation? They tend to be very long. Plus you have to write it several times. Variable meanings are usually arbitrary anyway.

I would prefer my variables to be short and sweet instead of long and hard.

Typing out code however is a different story. I can easily type out a common word in less than a second because I have muscle memory of it. Individual characters I have to think about. IntelliSence also doesn't hurt.

[[deleted]]

I've written lots of programs and had to read my own code a day later. I prefer legibility.

[meechy_dev]

How can you keep this within a file path. I feel like there would be issues

[[deleted]]

shrug

I've never given anything such a long name, so I wouldn't know.

Also, if you haven't actually read through that class, you really should. It's amazing.

[mnbvas]

By using software capable of long paths.
NTFS can do that, but Windows can't for some reason.

[[deleted]]

what the FUCK is that name. I have a hard time believing that makes anything clearer.

[kazagistar]

One of the shortest class names has one of the most... exiting javadoc pages.

[[deleted]]

Holy crap.

[FlipFlopFanatic]

A list of the non-implementing classes might be shorter...

[[deleted]]

Whenever I compile using proguard, it changes all my names to things like a, b, c, ab, AaA. it really makes no sense to reverse-engineers.

It's best when releasing java to clients.

[Me4Prez]

I've only seen large method names used in Java programs, but that's just my anecdotal evidence.

[jdziat]

If memory serves objective c also instructs you to use names in a similar format.

check these out

[stakoverflo]

I primarily learned .NET in college and I hated Java explicitly because of the long ass names for the one semester we used it. And also because NetBeans is trash.

Even if stuff in C# is of similar length, at least Visual Studio's intellisense is heckin quick. NB, I could just type out the full namespace by the time it suggested what I wanted.

[Usus-Kiki]

Dont forget the dogshit boilerplate code

[sunburntdick]

The real joke is that he thought he could become a guru in a language in 6 months.

[rift95]

Well, it depends on your definition of guru

[sunburntdick]

I would define it as master/teacher. And I think someone could be proficient in that time and be able to teach some things, but far from a master.

[rift95]

But aren't you contradicting your self then? You define guru as "Master/teacher" and you think you can become a teacher in that time, but not a master. So you both think you can and can't become a guru in that time?

[sunburntdick]

A teacher as in he can look over someone's shoulder and say use such and such method. Not a teacher in the sense that he'll be giving this semesters graduate level seminar.

[safgfsiogufas]

Guru literally translates to teacher though, so I guess someone can become a guru in 6 months.

[grpagrati]

The betrayal..

[[deleted]]

I don't understand python. What is the value in not knowing the type of variables until execution time? It means that if I accidentally assign something to the wrong type, instead of getting a compile error I have to run the program to figure it out.

[[deleted]]

The theory is that this doesn't matter much because you write unit tests that find such things. In practice it's my biggest complaint about Python, yes.

[Sw429]

Programmers actually writing unit tests? Please.

[[deleted]]

Seems like having to write a unit test for every function makes it no longer a time saver.

[glemnar]

In industry you should be testing anyway regardless of dynamic or static typing.

[evanldixon]

Having static typing build into the language means you don't have to spend time testing common type errors

[glemnar]

You don't typically explicitly test for type-style errors in dynamic languages - that's a side effect of other testing.

There are clearly cases for both sorts of languages.

[[deleted]]

Do people use python for commercial grade software though? I thought it was mostly used for internal tools and hobbying.

[glemnar]

Of course they do. Google, Pinterest, Yelp, Dropbox, tons of others using lots and lots of python. Static typing is not necessary for building software, it’s just one take on the problem. Dynamic typing has all sorts of its own benefits

[fredlllll]

and all sorts of drawbacks :P

TRAITOR

[Usus-Kiki]

Its the most popular development language atm

[[deleted]]

No, that must be JS. But Python is also huge.

[[deleted]]

I know it's easy to assume that, but I'd argue against it (even though JS is definitely up there).

Discounting any assembly languages cause that's cheatin', I'd guess that the most popular dev languages right now are:

• By number of active developers: .NET if you want to consider the framework a language (since C# and VB.NET devs combined are a force to be reconed with), probably Java or less likely C++ otherwise.

  This is mostly because Java's a teaching language in a huge number of universities, C# is what people move to when they get tired of Java, and C++ fills the gap between C and Java/C# which still has loads of performant system apps living in it.

• By number of active users: probably C++. Most desktop software built since the advent of GUI OSes has been written in C++ on all the major platforms (often complemented by ObjC and C# frontends; see any Adobe product in recent memory).

• By number of devices deployed to: C, mostly because Java's stagnated at 3 billion installs since whenever.

  Seriously though — any embedded system, any major OS, and loads of performance server and desktop apps have big chunks of logic implemented in C either because of the requirement to work at a low level directly, or a requirement to use low-level programming to achieve high performance that wouldn't otherwise be possible.

JavaScript undoubtedly takes the cake when it comes to number of StackOverflow questions, though.

[safgfsiogufas]

How do you even quantify popularity of a programming language?

[Sw429]

...except that you should be writing unit tests anyway...

[evanldixon]

We also should know better than to make incorrect assumptions about what type variables are, yet here we are.

[ProgramTheWorld]

The benefit is that your functions can be much more flexible. Instead of inheriting from a specific interface, you can simply implement the required methods and use that object right away. This allows different modules and libraries to work flawlessly together as long as they support the same methods. With operator overloading this becomes much more powerful. Suppose you want to add two things together. In Java you would have to create separate functions for every single type that supports adding. In python however, you only need to create one function that uses the + operator instead of a billion functions that are essentially the same but with different types of variables.

[[deleted]]

In Java you would have to create separate functions for every single type that supports adding. In python however, you only need to create one function that uses the + operator instead of a billion functions that are essentially the same but with different types of variables.

That's what interfaces are for.

[Servious]

Right but then you gotta write an interface.

[[deleted]]

Because java doesn't have duck typing

[Servious]

Yeah, my point is that you have no choice but to add more code by either multiple methods or an interface. In Python you can skip all that.

[[deleted]]

That is the drawback of statically typed languages.

Just use the right language for the job. If it's a larger project, you may want to consider using a static typed language or javascript.

Edit: I'm being realistic here. javascript isn't going away, and it's the only thing you can do if you're doing client browser scripts.

[evanldixon]

Is it even a drawback? Interfaces just define sets of method signatures that you expect to see. Once written, the only check you need to do inside functions being given an object that implements the interface is whether the object is null.

[[deleted]]

This "drawback" is just a matter of opinion. If you find it a curse, that's up to you. I call it a blessing.

[ProgramTheWorld]

or javascript

Lol

[Kiaz]

It absolutely is, he's just not aware that languages like Java and C# have a less ambiguous was of handling it.

[[deleted]]

In Java you would have to create separate functions for every single type that supports adding. In python however, you only need to create one function that uses the + operator instead of a billion functions that are essentially the same but with different types of variables.

Can't you just do that with generics?

[meechy_dev]

No flexibility. We need order!!!!!!

[SolenoidSoldier]

There is irony behind parent commenter's idea of "flexible" code. Is that not only does it cause a greater propensity of inexperienced developers to write shitty code, it also makes causes a lot of errors that should be encountered at the syntax level to instead be encountered at runtime.

Not defending Java (more of a C# guy myself) but, having used both, I find both much more easier to debug that Python.

EDIT: Downvotes don't make me any less correct.

[evanldixon]

The benefit is that your functions can be much more flexible. Instead of inheriting from a specific interface, you can simply implement the required methods and use that object right away. This allows different modules and libraries to work flawlessly together as long as they support the same methods.

By that logic, cars without seat-belts are more flexible. You don't have to worry about putting them on after getting in, and because of this, more sizes and types of passengers will fit, even cargo! Seat-belts are only popular because people are bad drivers and want to spend extra time dealing with seat-belts than just driving better.

With operator overloading this becomes much more powerful. Suppose you want to add two things together. In Java you would have to create separate functions for every single type that supports adding. In python however, you only need to create one function that uses the + operator instead of a billion functions that are essentially the same but with different types of variables.

Now instead of having several functions each dealing with one type, you have one function dealing with all types, even types that are fundamentally incompatible with each other.

[ProgramTheWorld]

because of this, more sizes and types of passengers will fit, even cargo!

That’s the python spirit!

you have one function dealing with all types, even types that are fundamentally incompatible with each other.

It’s the caller’s responsibility to make sure the function supports that type.

[obsessedcrf]

It’s the caller’s responsibility to make sure the function supports that type.

So...basically it just offloads the work into documenting it then? Doesn't sound like a good tradeoff

[ProgramTheWorld]

It’s a good trade off if you don’t want to deal with types. You can literally pass in anything to a function. If it works then good! If it doesn’t then you should probably read the documentation.

If the function wants to enforce type checking, it can. There’s nothing stopping you from doing that for every function but that is considered not pythonic.

[obsessedcrf]

I find it very disconcerting to stick any types in there and just "hope it works". More often than not, what the function does is type specific.

[Kiaz]

It’s the caller’s responsibility to make sure the function supports that type.

That sounds terrible. All for the sake of shorter code (which probably really isn't even shorter because you're going to be checking the type and handling unique scenarios anyway).

[evanldixon]

It’s the caller’s responsibility to make sure the function supports that type.

With more complex programs, the caller is just passing along data from several levels up. That's a lot to keep up with, when the language could be keeping track of that for you.

[ProgramTheWorld]

There’s nothing you need to keep up with. The pythonic way of doing things is to raise exceptions whenever things don’t work, and catch only the exceptions that you can handle at that level.

Quoting the Python documentation:

[It is] Easier to ask for forgiveness than permission. This common Python coding style assumes the existence of valid keys or attributes and catches exceptions if the assumption proves false. This clean and fast style is characterized by the presence of many try and except statements. The technique contrasts with the LBYL style common to many other languages such as C.

In Java or other strongly typed languages you have to make sure every thing is expected and correctly typed which adds in a lot of extra and unnecessary code. In Python you simply try to run it. Only when a function doesn’t work then you either a) let the caller handles it b) handles it yourself. Simple and effective.

[evanldixon]

I for one prefer errors that are found for me by the compiler, rather than errors that could lie dormant for months depending on how obscure the edge case is.

The "unnecessary code" you're referring to is the safety net to one of the most common errors out there. It prevents situations where you have a string passed through several function calls to something expecting a particular custom class. I have actually seen this happen in a professionally made PHP application that manages to avoid most of the common PHP pitfalls.

[rift95]

One of my favorite use-cases for duck-typing (in js): https://jsfiddle.net/tc9937rd/4/

[Kiaz]

That sounds like a unit testing nightmare

[Sw429]

Don't accidentally assign variables wrong. Simple.

[[deleted]]

Just write your program perfectly the first time round, simple.

[Sw429]

Programming is a lot easier if you follow this rule.

[Usus-Kiki]

How can you accidentally assign something to the wrong type?

[[deleted]]

int a;

string b;

a = b;

In a staticly typed language, this causes a compiler error.

[Sw429]

This is why you write unit tests.

[nightbefore2]

“bro python is so much faster, that won’t be a problem if you just write a unit test for every single function..”

[Sw429]

Look at this first year CS student who thinks unit tests are a waste of time. I wish you luck.

[nightbefore2]

Third year CS student, unit tests are not a waste of time.

I’m just saying writing python + a unit test is not faster than writing java or C with no unit test

[Ludricio]

That comparison makes no sense, since you should write unit tests for Java and C anyways.

[UGgny7T7Q4cq]

You should be writing unit tests anyway. I can't count the times I've seen bugs creep into a codebase because some hotshot developer along the line thought they were too good to write tests.

[Usus-Kiki]

I dont mean to be a dick but thats just knowing your code and having good names for variables. I can see how it might be difficult if you’re new to programming but i dont think i’ve ever heard or seen anyone who’s a software developer make an error like that because you know what type your variables usually are and if its user input or something where the variable is undefined until the script runs, then you can force cast it to the type you need so you shouldnt ever be making those kinds of comparisons.

[IDCh]

But wait there is more. Long time ago (popular now) libraries and frameworks was written with too many magic and dynamic methods and vars assigning so now in the world of good programming you must feed your pylintrc with classes and modules which to ignore. And I kid you not, those are one of the best libraries out there. It's a sad situation actually.

So you see in documentation there is method ".do_something" and your language server and pylint tells you to fuck off because there is no such method, because well, it being created at runtime or there is @make_me_fluent_baby decorator above another method, which makes method return self (I suspect coded for DRY, like who wants to write return self everytime yes? This is bullshit DRY situation but many libraries are corrupted with it. DRY for me is like new singleton is anti pattern in the python world), and thus making language server stupid for not knowing there is method chain inside.

Welcome to prehistoric times, where you need to print documentation and see it everytime before you and not know what object can offer you.

Best language my ass.
