Fuck yourself

I'm learning Scala and I'm trying to find a more funcional way to program these if statements,where I store auxiliar vars to make a final division, is there a better way?

     var sum: Double = matrix(col)(row)
     var div: Double = 1
     if (matrix.isDefinedAt(col-1)) {
        sum = sum + matrix(col-1)(row)
        div = div + 1
      }
      if (matrix(col).isDefinedAt(row-1)) {
        sum = sum + data(col)(row-1)
        div = div + 1
      }      
      round(sum/div)
    } 

Rust has the potential to be a C++ killer in many domains where C++ is currently king, but whether it will achieve this is not yet certain

It needs a syntax re-write.

>>60905387
Syntax is fine once you actually get used to it

>>60905395
>Syntax is fine

let ch = text.chars().nth(0).unwrap();

in rust if you pass a reference to an assignable object through a pipe to another thread and then try to use this reference yourself the program won't compile. how do rustfags defend this?

>>60905489
A Rust program's memory consists of a static set of items and a heap. Immutable portions of the heap may be safely shared between threads, mutable portions may not be safely shared, but several mechanisms for effectively-safe sharing of mutable values, built on unsafe code but enforcing a safe locking discipline, exist in the standard library.

Allocations in the stack consist of variables, and allocations in the heap consist of boxes.
The items of a program are those functions, modules and types that have their value calculated at compile-time and stored uniquely in the memory image of the rust process. Items are neither dynamically allocated nor freed.

The heap is a general term that describes boxes. The lifetime of an allocation in the heap depends on the lifetime of the box values pointing to it. Since box values may themselves be passed in and out of frames, or stored in the heap, heap allocations may outlive the frame they are allocated within. An allocation in the heap is guaranteed to reside at a single location in the heap for the whole lifetime of the allocation - it will never be relocated as a result of moving a box value.When a stack frame is exited, its local allocations are all released, and its references to boxes are dropped.A variable is a component of a stack frame, either a named function parameter, an anonymous temporary, or a named local variable.

A local variable (or stack-local allocation) holds a value directly, allocated within the stack's memory. The value is a part of the stack frame.

It's not that format strings are a bad optional feature it's that they mix code and data in an unfortunate way.
Solves trivial problems usually.
All that's required for them to be good is for there to be a string unpack method (hopefully at compile time where possible) which extracts the different arguments to their correct place.
But that's a messy system in realistic situations frankly.

I don't like features that help the easy problems. Clutters the languages a lot. Addressing the hard problems in a language is much more important. It could be done in string processing but I haven't come up with a good solution. Because hard problems are hard. Things like adjusting for internationalization is usually done through full string replacement. Which sets additional requirements on your font rendering and size adjustments. It works. But I wouldn't describe it as ideal.

According to wikipedia, it was 2005.

Ben Bitdiddle has invented a test to determine whether the interpreter he is faced with is using applicative-order evaluation or normal-order evaluation. He defines the following two procedures:

(define (p) (p))
(define (test x y)
  (if (= x 0)
      0
      y))

Then he evaluates the expression

(test 0 (p))

What behavior will Ben observe with an interpreter that uses applicative-order evaluation?
What behavior will he observe with an interpreter that uses normal-order evaluation?

In applicative order, this stalls because the arguments (including the loop (p)) are evaluated before applying the function. In normal order, the expressions are only evaluated when they need to be immediately reduced, which never happens to (p) because of the branch.

How is that changing state? Mathematically, there is no difference between a constant and a constant function - and any constant function can be expressed as a function of zero arguments.

>>60906979
The point is that in a proper programming language both (define (p) ...) and (define p ....) should be the same thing.

>>60906954
Thanks papa.

>>60906979
That's true in a pure language, but in an impure language (guess what -- impure languages matter!!) you can think of every function as carrying an implicit argument and returning an implicit result, that being the global state which can change after every invocation.

Also even in Haskell, a loop like

p :: a
p = p

will stall the interpreter, even though "it's a function with no arguments, and therefore a constant value"

I've been working on finishing my >java studies

as I finished, I'm trying to switch to Intellij Idea as my main IDE, but I'm having trouble adapting to the way it's GUI system works

it's rather similar on some aspects, but somehow I still can't get it to perform actions (they're called Listeners on it I believe) and to launch the GUI on screen when running the program

I did a quick attempt at letting it create an object with some information, as shown here:

public class La {

    private JButton button1;
    private JTextField txtAccName;
    private JTextField txtName;
    private JTextField txtLName;
    private JTextField txtPhone;

    public La() {
        button1.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent mouseEvent) {
                super.mouseClicked(mouseEvent);
                Account c1 = new Account(Integer.parseInt(txtAccName.getText()), txtName.getText(), txtLName.getText(),Integer.parseInt(txtPhone.getText()));
                JOptionPane.showMessageDialog(null, "Created successfully");
            }
        });
    }
}

this differs greatly from what Netbeans shows and does, so I'm not sure if I'm doing something wrong or what the fuck's going on here

I'd really appreciate a hand

What python module should I use to do something when I press a shortcut key combo?

Everything I've programmed starts from the top and works its way to the bottom? Can it do more than one thing at a time?

http://lua-users.org/wiki/PatternsTutorial
>Limitations of Lua patterns
>Especially if you're used to other languages with regular expressions, you might expect to be able to do stuff like this:
>'(foo)+' -- match the string "foo" repeated one or more times
>'(foo|bar)' -- match either the string "foo" or the string "bar"
>Unfortunately Lua patterns do not support this, only single characters can be repeated or chosen between, not sub-patterns or strings.
>only single characters can be chosen between.

But I don't see how. I'm looking to sanitize some input where ! and / are forbidden at the start of the string (but I aim to just strip them, not throw away the string).
So I could do that by matching "/-!-%a" in lua (- meaning zero or more if possible, %a meaning letter). But that doesn't catch alternating ! and / like (\!|\/)+\w would in regex.
I've looked at various documentation but I can't find a trace of it. Does anyone have any ideas about why this is?
The hacky solution would be to just do repeated /-!-/-!-/-!-/-!-/-!- for a while so I catch some number of them, that'd work but it's very ugly.
Performance isn't really a concern luckily.

>>60907585
traps aren't gay


python is

>>60907585
No.
Think of the hierarchy of all possible logical propositions as like the shittiest road system ever: namely, a network of one way streets. A one way street from P to Q exists if and only if P implies Q in all possible worlds.
Traps are gay, so there's a one way street from traps to gay.
Traps are programming, so there's a one way street from traps to programming.
The logic error you're making here is that you're seeing a path between programming and gay, and thinking to yourself, oh, that looks like a path I can mentally traverse. The reason this is erroneous is because one of the streets in that path is facing the wrong way. You're trying to get from programming to traps and then from traps to gay, but you can't get from programming to traps, because it's a one way street and it goes the other way: from traps to programming.

Alright friends, pretty much 'learnt how to program' through Python recently. Understand all the data types, control structures, object orientation; majority of the basics.

What I'm most interested in is predictive learning and all that shit. For a little fun I sort of want to analyse penny stocks (on the ASX because I'm in Australia). Is there any places that you guys know of for accessing this data for free, or for little cost at least; even if it's like 20 mins delayed or something. I guess even archived, but recent, data would even work for what I'm planning on doing.

Surely some companies might just have some realtime code that you can import in and just call for a certain amount of data you want? Or am I thinking that this is all a lot more open than it actually is? That'd have to be the way 'real time' data works right, seeing as you can't just read in a .csv file if it's constantly being updated?

tl;dr

Any easy way to access penny stock data (ASX specifically), for free (or for not too much)? And any useful ways for dealing with this constant flow of information within Python?

New Python user here. What is the most common way to run Python when sharing scripts/programs? Are those not its intentions? Like with JS you can embed your game/code in a web page and send someone the link, in java you can send someone an executable jar file. Does Python not have this? I love Python for just opening up and starting work right away unlike most other languages though.

>>60908958
d looks interesting.
does the module/import system work well?
how long are the compile times?
how annoying is the gc/the libraries that use it?

>>60909044
I haven't used python in a professional setting but I just use https://anthony-tuininga.github.io/cx_Freeze/
>you can just send someone a jar file
Not really. That relies on the JVM being installed. You can create java executables that contain the JVM and run an instance of that for your program. That's the common way you'd ship java without requiring too much of the environment. cx_freeze is similar i believe (haven't looked into details).

>>60909044
For simple scripts, you would most commonly require that the someone you are sharing the script with has a compatible version of python installed.

This is not that different from jar binaries--those require that the JRE is installed.

There are ways to compile python programs to binaries (such as .exe) though. Usually the compilation will output multiple files, and so for larger projects you might consider using an installer.

>GC
>annoying
Anon GC isn't annoying unless you're a very specialized individual. And if you are that kind of individual then it's pretty awful right now. You can't use very large parts of the standard stuff. But you cna still catch all of that easily by marking @nogc (or i believe there's a compiler flag) so it's not really annoying besides what you're lacking.
Most of the GC utilizing features are harmless to programs though. It's if you rely on the GC for your allocations that you'd really begin to care.
>modules
Feels great
>compile times
Way better than C++ but I find compile times for virtually every language underwhelming. It's objectively good though.

>>60907845
>still haven't found a solution

string.rep("/-!-", 30)..

That's not too bad though.

>>60909065
Why of course. Although it doesn't have a state-of-the art build system like Rust's cargo and module system

use std{stdio, algorithm, range}; would be really nice. But it's better than writing header files

On linux though you can run Python without being installed or am I being dense? You still have to have the library?

It's installed by default on a lot of distributions. Just like gcc
>being able to run his programs from the command line
Probably this:
https://en.wikipedia.org/wiki/Shebang_(Unix)
But there's also other ways to do it.
You just put

#!/usr/bin/env python

at the top of your script.

I haven't thought about it much but maybe you can set up file extensions associations for terminals so they run without you needing the shebang.

Enjoy doing unnecessary computations at runtime.

What are some efficient sorting functions that don't guarantee perfect sorting? The goal is to achieve an ordering that's coarsely correct and improves over time. Ideally I'd have a max delta. I don't want the order completely wrong at any point. But if maybe 50 elements or so are scambled but they're sorted with regards to external elements that'd be great. I'm only on multi-core machines so no need to constrain to non-parallel bigO.

Also how do people find algorithms based on their requirements?

>Enjoy doing unnecessary computations at runtime.
Are you serious man? Have you even used templates? Templates are one of the biggest compile time hogs in existance. You could run an entire metaprogramming preprocessor on the language (which many do actually) and still save time compared to C++ templates. They're extremely bad at that.

Because if you didn't that'd imply you're a clueless spoonfed baby.
Great anon.

maybe i do, maybe i don't

I don't particularly care because you've established you're not particularly friendly. And I think that implies a lack of correctness, had it affirmed many times.

(p) is defined as a recursive procedure with no arguments/.when evaluated, it will fall in an infinite self-evaluating loop.(test) procedure is defined as a procedure with two arguments.because the interpreter uses applicative order evaluation, when test is called, first it 'looks at'(evaluates) the two arguments ( x y) and when y (p) is evaluated, (p) is called and the program falls in an infinite loop.given an interpreter using applicative order of evaluation, the body of the (test) procedure will never get the chance to be executed.with a normal order evaluation interpreter, the interpreter doesn't look at the arguments, unless it is needed, so the test should be executed and (test) should return 0. (if) conditional is a special form, because it also evaluates an expression only if needed.(if #f (p) 13) returns 13.

What should I code. I can never think of anything useful to code and improve

Its was just one actually, and it was my biggest project to date.
When executed it copies itself to the system folders and set it to launch on startup.
Then I can connect to it whenever I want and perform a set of commands like file/folder manipulation, download/upload files, take screenshot, etc
Its been ages that I don't mess with it though
