Based fucking Apple

I'm in undergrad right now, and was thinking of going to grad school. An area I'm interested in is machine learning and ai stuff, but I'm open to anything. What programs should I look at?

I don't fully understand what's going on in the getMd5 class, could someone explain to me what happens?

package md5generator;

import java.math.BigInteger;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.Scanner;

public class MD5generator {

    public static String getMd5(String passwordInput) throws NoSuchAlgorithmException {
        MessageDigest md5Digest = MessageDigest.getInstance("MD5");
        md5Digest.update(passwordInput.getBytes());
        BigInteger hashInt = new BigInteger(1, md5Digest.digest());
        return String.format("%1$032X", hashInt);
    }

    public static void main(String[] args) throws NoSuchAlgorithmException {
        //Declare user input scanner
        Scanner input = new Scanner(System.in);
        String password = "StrongestPasswordInTheWorld";
        while (!password.equals("")) {

            //User enters password
            System.out.println("Enter password: ");
            password = input.nextLine();
            //Program generates MD5 hash for input password
            String hashedPassword = getMd5(password);
            //Prints out user input password and hash
            System.out.println("Password: " + password);
            System.out.println("MD5 Hash: " + hashedPassword);

        }
    }
}

MessageDigest is initialized.
The object is updated with password.
The digest is obtained and converted to BigInteger.
The BigInteger is then converted to hex represantation.

Unless made to by a workplace, I will never develop applications for iOS. I do not like the idea of having to ask Apple permission to distribute an application to their users. I'd rather just distribute the binary directly.

I am willing to make applications for Android, despite how unpleasant the experience is, because I never have to interact with Google to get the application to the target market unless I want to. If Google thinks the application is trash, or it interferes with their bottom line (maybe it allows users to use Youtube Background Play without having a Youtube Red account), I can distribute the binary directly to my customers without their go ahead.

getMd5 is not a class; it is a function that takes as input a string, and returns the MD5 hash of that string.

>>52225818

To be honest, even if I were rich, I wouldn't use iOS. Despite all of the buzz we had last year about Android and the stagefright vulnerability, iOS actually managed to have more publicly disclosed vulnerabilities last year than not just Android, but Adobe Flash as well. If I use an OS like Cyanogenmod, then I can get security updates quickly without ever compromising my ability to use my mobile devices with the same level of freedom as I would my laptop.

>>52225822

I am well aware of the good community behind iOS jailbreaking. Nonethless, as a security-minded person, it is unsettling to have to think "the reason that I am able to do this on my phone is because there is a vulnerability on it that anyone could exploit, not just me; and if I patch this by using official security updates, I will lose this freedom."

Languages I use on a regular basis:

Ruby

C++

Languages I have used in at least one personal project and/or school assignment, but do not use normally:

Java
PHP
JavaScript (and CoffeeScript)
Ada
Racket
Python
C#
x86 Assembly

Languages I've fiddled with at least once:

A couple of Lisps/Schemes (I like TinyScheme)
Powershell
Rust
F# (for like a day or two. It's meh).
Objective-C

I've written a little bit of these here and there (not all of these are considered programming languages, but some are arguably turing complete):

Bash
GNU Make
HTML
CSS
SQL
LaTeX
XML

Honorable mention:

KPL (Kernel Programming Language). A language some professor made up to make teaching operating systems easier. It compiles to an architecture he made called Blitz. Basically, it's just a system's language with some debug functions. Had to use for an operating systems class.

In JS, is there anything wrong with creating new objects within an object literal that's being used as a module?
Like,

var Foo = {
    bar: new asdf(0),

    xyz: new asdf(1)
}

Or should the creation of the objects be done outside of the module (while still being properties of it)? I normally just fuck around in global namespace because I never made a serious project, but I'm trying to go modular.

>>52226246

If you want code to be used in other projects, do not use the global namespace for shit. If this is just for one project, feel free to pollute it, so long as you do not import methods that will conflict with your own.

Guys i'm trying to make a mastermind algorithm (really simple i'm only doing this using random and intergers).

I think you should put them in an array so you can iterate though them
that should help with checking

// pseudocode obviously
noduplicate = true
for i = 0 to 3 // iterate first term for comparison
    for j = 0 to 3 // iterate second term for comparison
        noduplicate = noduplicate && mstrmind_random[i] != mstrmind_random[j] // this will flip noduplicate to false as soon as it encounters a duplicate

it's a pretty inefficient way to check for duplicates because it's got tonnes of obvious redundant checks but you've only got 4 terms so who cares

then wrap your random generation in a while loop like this

bool noduplicate = false

while !noduplicate
    // your code goes here
    // above code goes here

>>52226694
I mean an array of integers

int[] mstrmind_random = new int[4];
mstrmind_random[0] = random.nextInt(10);
mstrmind_random[1] = random.nextInt(10);
mstrmind_random[2] = random.nextInt(10);
mstrmind_random[3] = random.nextInt(10);

or

for (int i = 0; i < mstrmind_random.length; i++) {
    mstrmind_random[i] = random.nextInt(10);
}

noduplicate is just a boolean I declared
you can write that in a different way

bool foundDuplicate = false;

for (int i = 0; i < mstrmind_random.length; i++) {
    for (int j = 0; j < mstrmind_random.length; j++) {
        if (mstrmind_random[i] == mstrmind_random[j]) {
            foundDuplicate = true;

}

>>52226814
Why can't you use arrays? Are you a student and the question doesn't involve them, or have you just never used them before?

If it's the latter, there's really only one solution to that, and they're pretty simple, and incredibly useful, when you get used to them

if you don't want to you could still write out each comparison if you really need to

if (mstrmind_random0 == mstrmind_random1 ||
    mstrmind_random0 == mstrmind_random2 ||
    mstrmind_random0 == mstrmind_random3 ||
    mstrmind_random1 == mstrmind_random2 ||
    mstrmind_random1 == mstrmind_random3 ||
    mstrmind_random2 == mstrmind_random3) {
    
    // run this code if there are duplicates
}

Now I want to get started on the graphical work. In school I was taught Swing, is this the best approach?

Also, how can I implement a path selection dialog as easy as possible? I don't really know what to look for, and all my googling is giving me the good old "JAVA_HOME Path problem" links. As the project is now, I have to manually type (or copy/paste) the path into the console, which is not ideal, lol. Any particular things I should read up on?

Any help and tips would be greatly appreciated!

Is a programmer's code quality inversely proportional to the amount of terminal rice and scripts they've crammed into their .bashrc?

>>52227012
no it's counter proportional, good devs don't care about the env, they just hack the code

>>52227012
Nothing is ever that simple. But people who are interested in ricing are mostly people who want to "get into coding because it would be cool to know coding", and thus they only learn so much that they can show it off to people without really having too much insight. So a riced up build doesn't automatically scream "THIS PERSON CAN'T CODE" in my opinion, but I think it's likely that the person is one of the people I described earlier in this post.

java compiles to bytecode which runs on a virtual machine. Oracle writes and compiles versions of the virtual machine to support other platforms
this was done so you only have to compile once and it will run on any system for which there exists a version of the virtual machine, but the added layer between the code you write and the instructions the computer executes tends to slow things down a bit
it used to be worse, but it's still getting better

other languages like C/C++ compile to architecture-specific code, which is generally faster, but you have to recompile for each different architecture you want to support

if you're just writing it to learn it'll probably be fine but be warned java can be anything from a bit slower than (well written) C/C++ code, to tonnes slower

as a general rule though, formulating a more efficient algorithm to do something, or eliminating redundant code, is going to be 100x more effective optimisation that switching to a 'faster' language
cracking MD5's, though, can't really be optimised, so switching to a faster language is kind of the only option for improving speed

Thanks dude, informative and well-constructed 5-star post.

I'm using Java because that's what I learned in school. I've been checking out C/C++/C# a tiny bit, but it seems a little overwhelming (probably because I haven't done so much with it), it's probably easier than I think right now tho. I always try to keep my programs at a minimum amount of operations to get where I want, but I agree that when the workload is simply fucktons of repetitions, there really are close to no optimizations to do. Maybe when I'm done with the Java one, I'll try to recreate it in C/C++ to learn that language.

Ask your beloved programming literate anything

>>52226962
java, the programming language, is not slow or fast but the implementations of java are usually slower than the ones for c or c++ because java

- needs a runtime (garbage collection)
- has no explicit memory management
- has implicit bounds checking on arrays.
- has more level of indirection (because of GC and virtual)
- enforces exceptions (= more checking to do)
- has no unsigned types

and probably other reasons that i can't think off.

>>52227072
>java compiles to bytecode which runs on a virtual machine
Compiling java code aot or java bytecode aot is a thing. some compilers actually does that (gcj, excelsior)

>>52227178
C++ gets a bit silly at times
the syntax can sometimes be absurdly difficult for humans to read (and, incidentally, for compilers to read. That's one of the reasons it takes so long to compile)

it's going to overwhelm you at first, so you either have to persevere to crack it, or just give up and use a similar language with nicer syntax - I'd suggest D but it's kind of niche so there isn't much support for it online. You'd probably have to make an account for the forums or something and ask and wait (use the old trick of registering a female username and you'll cut wait times in half)

I'd have to say C# is probably the best way to go. It's not too much faster than java honestly, but it'll help you bridge the gap to C/C++

oh yeah and another thing - learning java you've probably been using IDEs like eclipse or netbeans. A lot of people find these to be more trouble than they're worth, and that just writing files manually with an editor and compiling with the command line can be a lot simpler. Personally I recommend atom, it's pretty neat

>>52227221
Yeah I'd heard about compiling java like that but I have no idea how it performs so I don't really feel knowledgeable enough to talk about it

>>52227311
But to answer your question:
Yes, every hashing mechanism is suffering from this problem when you limit it to a string of x characters. At some point, two different files HAS to get a matching checksum. Take MD5 for example.

The MD5 checksum consists of 32 hexadecimal characters. This means that there are [Very many] combinations available. However, programs can be as long as they ever want. So when you've made [Very many] unique programs, the next program you make is guaranteed to have the same checksum as one of the previous programs (if it hasn't already happened).

It's possible, yes, but it will take an ENORMOUS amount of time.

>>52227072
The VM isn't the only issue for performance.

Java also has a number of safety features (a program written in Java will never crash because of a mistake in Java code, only because of a mistake in native code or the language implementation), and those also have a performance cost even if the bytecode is being compiled to native code.

>10 is only divisible by 5

>>52227414
The tasks are nice and you get to learn the language and how it can be used, however I think they make it too easy since you don't have to repeat what you learned earlier when you progress to a new subject, it's all pre-filled in except for the task in question. Therefore, it's easy to forget what you just learned as you progress.

But if you're able to remember stuff after doing it once or twice, it's perfectly fine.

>>52227245
that's not how gets work

>>52227414
If you want to stay a babby, yes. Take the python course and finish it in less than a week. Get on projecteuler after and do as many problems as you can with python to test and build your knowledge. When you're stuck, don't straight up look the answer up, look up bits and pieces like "efficient python sieve" or "properties of pandigital numbers"

I don't know if it will work for you, but that's how I got gud at Python.

>>52227410
It's among the biggest though

I actually cannot believe I forgot to mention that java tends to eat memory like it's saving it for the winter
every object has a 1 byte overhead IIRC, and the handling of strings can only be described as 'fucking batshit insane'
since reading from memory is proportionately hugely slower than it used to be (meaning that in some cases it's actually tonnes more efficient to recompute a number rather than to store it in memory and get it back when you need to), this tends to impact performance a lot

also since automatic garbage collection is not something you generally want to place under a lot of stress (tends to be a lot slower than manual allocation / deletion), the performance drops due to larger memory usage are massively compounded

>>52227294
> the syntax can sometimes be absurdly difficult for humans to read (and, incidentally, for compilers to read. That's one of the reasons it takes so long to compile)

Parsing isn't the issue; the time taken to parse a C++ program is a minuscule fraction of the overall time.

One of the factors which makes C++ slower is that name resolution is far more complex due to classes, namespaces, templates, and argument-dependent lookup. The existence of these features increases the time even if they aren't actually used.

Another factor is the use of templates and the extensive use of inline functions, which means that the code actually being compiled is significantly more complex than what's in the source file. While these are only a factor to the extent that they're used, the standard library uses both extensively.

Parsing is definitely one reason
I probably shouldn't have specifically said 'syntax'
I was referring to the fact that a compiler has to spend loads of time trying to resolve the meaning of anything that's put into it (arguably because of OO shit, the weird template system, and context-sensitive-grammar everywhere)

>a Java String actually consists of more than one object
>a Java char takes up two bytes, even if you're using them to store boring old ASCII values that would fit into a single byte;
>a Java String contains some extra variables that you might not have considered.

I believe they're changing (or maybe have already changed, I don't know) the 3rd point there, which is good
basically the problem is the overhead, and the fact that String is bloated with other stuff which would be faster to compute on-the-fly on pretty much any modern hardware profile

> I was referring to the fact that a compiler has to spend loads of time trying to resolve the meaning of anything that's put into it (arguably because of OO shit, the weird template system, and context-sensitive-grammar everywhere)
There isn't really much context-sensitive grammar (the actual grammar given in the standard isn't itself context-sensitive, but classifying certain tokens requires a lexical tie-in).

Bear in mind that the grammar only needs to specify enough detail that correct programs are parsed correctly. It does not need to distinguish between correct and incorrect programs, nor does it need to get involved in name resolution.

This is why e.g. the most vexing parse is resolved statically as a function declaration rather than an initialisation (taking into account whether the argument is a valid expression would make the grammar context-sensitive). You parse it one way, check that the result is valid (doesn't violate any constraints), if it isn't you report an error (i.e. you don't vary the passing according to what, if anything, an identifier refers to).

The other parts (i.e. name resolution) aren't parsing, they're compilation. Any performance hit isn't because the syntax is hard for a compiler, it's because the semantics are. But those semantics are a large part of what makes C++ powerful. You can do a lot at compile time to improve run-time performance (e.g. template expansion and function inlining).

I've got to confess I never did a real degree so my knowledge of the terms is a bit iffy at times
I did say syntax was the wrong word to use, and by extension parsing wasn't really what I meant

>>52228194
Well, the tl;dr version is that compiling C++ programs is slow so that running them is fast.

The syntax is ugly because C++ adds a boatload of new features to C while trying to use essentially the same syntax. But changing the syntax wouldn't make compilation any faster.

C was designed to be compiled. The whole point of the language it to be a high performance portable language. There is not much consideration in the language for making it good for scripting. It can be used for scripting of course, but it was not designed for that.

A scripting language is when you are using a programming language for extending a specific software/program. some examples are c# for unity3d, mircscript for mirc, javascript for internet browsers, C for linux, ... You can't say that X or Y is a scripting language but that X or Y has been used as a scripting language. Being interpreted or compiled is irrelevant.

Well, rewrite it in C and let GCC do TCO. Or alternatively, rewrite it in another language that supports TCO.

>>52231704
C++

Ctards are too retarded to understand OOP or use high-level languages effectively. C is so fucking simple (= lacking in features) that if you go that route you may as well just program in assembly.

>>52231733
Okay.

What project are you working on though? Why do you need to decide on either C or C++?

>>52231704
C++ suffers from every programmer using a different subset of the language, otherwise it's more powerful unless the platform you are working on may not suffer from the slight performance loss of the provided abstractions.
C is preferred by some people because it's simpler, sometimes trading a bit of abstraction for the trait that everyone understands the features used in the code is worth it, although not always.
Overabstraction is a serious issue because around some time people started pushing the idea that less repetitive code is always better, when in reality, it's a tradeoff.

>>52231775
>it's simpler

>>52231767
I want to know which language should I learn. I started with C, because it should be simpler but I'm starting to like the OOP approach of C++, specially for someone that wants to gamedev later.

Exactly one of the reasons I started with C.

Definitely C++. (and x86 Assembly if you want to be a cool kid)

>>52231831
This is true and definetly a reason to use C++, although some of the more talented game devs have noted that they prefer to use mostly only the C subset of the language, because of said trade of clarity for everyone vs abstraction and abstraction vs performance.

Hard to believe he's worked in the industry and not realised the lack of women in the industry is a resource problem, not some sexist scheme.

The question i think should be asked is "why are so few girls taking up programming", as a lack of them in the industry is just a symptom of a much bigger issue.

Anyone saying we need more women in the tech industry without conceding this point actually means they want to commodify the existing women in the industry. Which is pretty sexist.

>>52232229
Women don't like to program.

There are more programs and groups pushing women into STEM fields than ever before, and the walls of every institution are dripping with Women-In-[IT/STEM/Eng] scholarships.

They walk by these scholarships and sign up for liberal arts disciplines.

No one is saying that.

The tendency to adept to fields in STEM is just greatly influenced by biological differences between men and women, as well as cultural differences.

Even if the cultural differences are seen as a barrier, there are so many benefits for a woman to get into STEM that a rational mind would see that it's crazy not to take advantage of them.
