Scripting

Because they have a use case different than yours, simply want to have rapid deployment, or don't want to have to spend hours fucking with shitty OOP implementations.

It's an interpreted programming language, by the way. Not a scripting language.

Python is a neat little language and it ties in very well with bash scripting. Also there are great libraries for bioinformatics.

Basically they need other things done than you in a faster manner. But Java is a great language, so keep going. It gets really interesting once you get into more advanced concepts such as database connections etc.

The assumptions in this statement show the special kind of retard you are. You know, you could find out why people use other languages by fucking learning them and using them a little.
I mean, by your (lack of) logic, why doesn't everyone use C, are they just too lazy to use a REAL MANS language or what?

now that we have .net core and all, can't you just fags all just move it? and if you need a dekstop application just use electron with typescript and react. its so fucking good compared to the java crap im forced to do for a living. any java advocate has to hung on some sort day of the rope.

proper object orientation has been the dominant paradigm for two decades at least. its the basis of all modern software design for good reason.

I can't even tell if you're serious at this point

>>57087993
First java is only compiled to an intermediate byte code, so it more "pseudo" compiled.
Second python is as you said good for scripts.
You will never write stuff you only need once or some prototype and so on in C/C++/Java/C#. Neither will you write programs that only have like 200 LoC.

>>57088641
Are you implying that java is in any way better than C#?
Because it is not.

>>57088771
>Python with strict typing

what is strict typing? is it some python feature or do you mean static typing?

>compile time bug checking.

java doesn't do that well enough, example: there is no Option<T> type (or anything comperable) and NullPointerExceptions aren't too uncommon as you probably know.

>Pro-tip: you can't. Now go back to your intro to computing 101 class, this thread is a conversation between actual software professionals.

dynamic languages offer you productivy and can be quite managable when you use a microserive RESTful approach (so each part of the app is actually dead simple).


>>57088841
but I want proper and working code completion but apparently its not that easy because of the build tooling fragmentation. Another things is the relative loss of productivity, in dynamic languages you have nice code generatos and CLI first approach, in java at least the libs and tools we use don't have such.

>>57088943
but with modern IDEs there is zero reason to use a scripting language.

>>57088497
I make larger applications using Python.

>>57088545
jokes on you
Python can EASILY be extended to use C or other low-level-ish coding for heavy computing

>>57088971
Writing code in scripting languages still is way faster(unless you go insane and make a big project).
And embedding interpreted scripts into your program still works better than working with compiled code.

Or gradle or ant. All are fairly complex when compared with the alternatives in the nodejs or dotnet world where you just issue a simple command like npm install and it werks.

you know modern languages have this feature called type interferance

>proper object orientation has been the dominant paradigm for two decades at least. its the basis of all modern software design for good reason.

is a class containing static constants really a class? I thought classes are blueprints. my problem is not OOP, my problem is that i have to abuse syntax. I want a namespace or a package kind of thing. I don't want to label something a class which clearly is not a one.

>I can't even tell if you're serious at this point

I might be spoiled but compared with the tuts on the Web stuff the java stuff is really bad. At least maybe in the thing I have to use currently which is JavaFX.

http://benchmarksgame.alioth.debian.org/u64q/which-programs-are-fastest.html

Handcrafted top of class C is generally ~twice as fast in special numeric benchmarks.
In real world applications the distance is probably much lower and there are some situations and benchmarks where Java is faster, like heap allocations or super synthetic benchmarks.

Ever heard of diminishing marginal returns? At a certain point, adding needless classes will have the opposite of the intended effect and make your code hard to maintain.

>>57087993
You might do it because it's easy to use for a quick and simple job. Languages like that have a place, not everything needs to be good for large scale applications.

>>57087993

Why would you chose Java over Python?
If the speed doens't matter (and it doesn't matter unless you do some heavy computation) Python is faster to type and more beautiful..

public class HelloWorld {
  public static void main (String[] args) {
    int    myCounter = 0;
    String myString = String.valueOf(myCounter);
    if (myString.equals("0")) {
      for (int i = 1; i < 10; i++) {
        System.out.println(i);
      }
    }
  }
}

vs.

myCounter = 0
myString = str(myCounter)
if myString == "0":
  for i in range(1,10):
    print i

>>57089023

Butthurt 'murricans because a lot of Java jobs in the US got outsourced because indians are cheaper.

>>57089676
purely procedural code done in an oop-language is going to look like shit in comparison forever and ever
the use of brackets is actually good if you have any experience in programming
types explicitly written out are actually good
the iteration by 1 is explicit vs implicit, how about you change it to let's say 5? what then? your pretty little idiom is not so pretty anymore
where are you printing to? maybe you want to print to .err instead of out? maybe you don't want to print a line, but something else... babbis pretty example need some mods doesn't it

Because it reduces development time, and in some cases the trade off between development time and execution time is highly worth it.

I am a firmware developer for a company where we mainly use C and Assembly, but I use Python from time to time to automate the build process, analyze data, and experiment with signal processing algorithms before implementing them in assembly, which takes a long ass time.

Not entirely sure but I think they kept a chunk of .NET proprietary. Things like coroutines and other small features were missing iirc but I gave up when I ran into a bunch of technical issues with the mono compiler which were likely my fault due to how I built the toolchain.

your project needs to be decomposed into multiple, smaller projects.

i'll send you and your company my consultation bill.

I have a project in java which is a few KLOC, to accomplish a task.

I was able to create a program in python to do the same (kind of, the scope was reduced a fair bit since it didn't need to have the same multicore and resiliency requirements as the java program since it was a demonstration for a class I was teaching) task in less than 300 lines of python, including documentation.

Basically, it's excellent for rapid prototyping, simple scripts, scientific computing, etc. but not so good for enterprise-type tasks.

>>57088605
>BI

That's too broad a definition of BI. You're thinking "real" data science, where statistical models are applied to cleaned data sources. BI is munging data and putting it into sources meant for big data reads, up until creating reports and administrating a reporting server. BI isn't at all the same as building statistical models, they just happen to share some tools (not R, python could be used for scripting ETL processes, but I'm guessing you're thinking of the statistical packages for it), and data science often relies on BI to provide a place to read data from.

For actual BI: Java (Cognos, most open source stuff), Scala (a lot of Hadoop map/reduce shit), possibly C# (Tableau) are probably what you're going for because everything is programmed in it.

Python is wonderful

>>57087993
Because you have to write thousands of LOC for even the smallest retarded thing you wanna do. And this really hinders you in large scale projects. Scala is an order of magnitude better. And Clojure is an order of magnitude better than Scala.

Because JVM. That shit is literally built to be the worst possible VM to run code in ever - and the funny part is that you can't actually change it because of retrocompatibility. For instance - JVM will never have TCO because of this.

Because OOP - the worst kind of it. What java authors had in mind is something different from what the creators of the paradigm had. The result? Awfully implemented static single-inheritance OOP-ish paradigm that sets shitloads of constraints on the way the application is engineered hindering the future design. Composition over inheritance? Cool - except it's not complete as a solution, and will only alleviate your suffering while trying to understand the architecture of the project you're working on.

And, if the customer decides to implement a feature that breaks the current object hierarchy, pray your fucking divinity whatever it is that the ticket doesn't get assigned to you, - because otherwise MONTHS of excruciating refactoring pile of shit are waiting for you to dive in. And, you're not even sure to succeed - not everyone is the fucking meganinjarockstar developer. You WILL encounter shitloads of undocumented and uncommented pajeet-tier spaghetti on your way to the ticket completion.

Learn it though: it's useful to know one of the most used prog langs in the world. But, if you really wanna have fun while programming, here is my advice - steer clear from that pile of crap. Or, if you REALLY need to use it - be sure that you're gonna work only with top-notch programmers, otherwise it'll be a tough ride.

>>57088771
