I just had a bad semester. My GPA went from 3.2 to 2.7.

I was doing really well until the start of last semester. I was getting lots of A's, and I got a high exam mark in a course I was struggling in.

The problem is that university is basically my whole world right now because I am doing it online. I flunked out of SENG in physical university and got banned for 3 years, and my only alternative was to do CS online. One of my friends immediately unfriended me on Facebook when he found out I wasn't coming back the next year. That was a huge blow, because i really liked him and we had similar personalities. The one who stuck with me is a bit of a Chad.

I have pretty much been hold up in my room for a year now, studying and gaming. I know what you are thinking, "He must be gaming all the time, so he's failing," but honestly, from like January to July I didn't touch any games. It wasn't some kind of nofap asceticism, I had just lost interest. Then, August came, and I had booked my first exams, but at the last minute, I backed out of them because I knew I was going to fail. I thought if I put in an extra month of study time it would make a difference, but it didn't. I started gaming again (multiplayer Minecraft autism), probably because of the dread of *knowing* I was going to fail two courses out of three. I also got drunk once, for the first time in like 2 years. I binged on beer after every exam to take the edge off.

I'm doing work experience, but instead of a sexy internship at one of the big 4, I am just doing work for some guy who put up an ad on the internet. He needs a mobile app built, and I'm making it. I've been clueless from day 1, and it's in a language I never used in uni. I am self teaching everything instead of learning from people who know what they are doing. It is nerve wracking, and I hate it.

My advice for /g/ is to not do online CS, ever. Figure out a way to go to a physical school, even if you have the discipline for online.

The worst part is the asynchronous sleep. It has been bothering me for months. There are rarely two days in a row when I wake up at the same time, and sometimes I get reversals so I wake up when the sun is setting and go to sleep in the morning.

class Node
{
    Node next;
    int data; 
    
    public Node(int d)
    {
        data = d; 
    }

class Node
{
    Node next;
    int data; 
    
    public Node(int data)
    {
        this.data = d; 
    }

Are these the same thing? I see the latter more but I want to understand the use and styling behind it.

Build some impressive projects and understand that internships are about 10x more impactful than GPA. INTERNSHIPS ARE EVERYTHING. People only give a fuck about GPA if you have 0 experience.

I've went way below 2.7 anon, it's really not relevant.
Just make sure you improve your skills and don't fail out.

>>57298534
one advantage of "this" is that you don't have to invent some dumb new name for the parameter to the constructor. this.data = data.

>>57298534
They are the same thing.
The syntactic rule is that if X is not in the local variable scope of the method, but X is a member of the class, then the expression 'X' becomes syntactic sugar for 'this.X'
The rule exists because people are too lazy to write 'this.' each time, but accidentally "shadowing" your members is pretty nasty, so it's a good idea to use 'this.'
A lot of times it is logical for contructor arguments to have the same name as the member variables, so you are required to use 'this.', for instance.

class Point {
  float x, y;
  public Point (float x, float y) {
    this.x = x;
    this.y = y;
  }
}

The alternative is to rename your constructor arguments

class Point {
  float x, y;
  public Point (float initX, float initY) {
    x = initX;
    y = initY;
  }
}

Best to just consult the project's style guide to see what is supposed to be used.

>>57298577
good for you

>>57298590
that's what I thought.

so literally 0 difference in the memory aside from storing a different name for the variable?

meant

this.data = data 

for the second block line, just a typo. you are forgiving anon

/this/ refers to internal variable defined in the class definition. Not sure if the first example compiles without warnings or errors. Think what would happen if in the first example you had data = data, it would do nothing. Also, in the second example it should read this.data = data.

Why would anyone want an IDE that's not VSCODE?

Doing a free trial of Mathematica 11 to see if it's worth the price but so far the answer is no. The neural network features are fun but don't really seem extensible enough to do anything new with, you can't even define new activation functions as far as I can tell. Also they're shipping with an outdated version of CUDA that can't handle the 1080's compute version and it doesn't seem like there's a way to change it so I'm CPU bound.

Sucks because as usual they've developed a really nice syntax around nets that makes for really fast prototyping and testing. Maybe 11.1 will be worth another look.

This bullshit took me way too long and is pretty poor in efficiency.

Just a calculator where you input formula through a String and it follows order of operations (just has + and - operators) and obeys parenthesis.

I made a thing.
http://pastebin.com/GVdL30B1
From the pro/g/ramming challenges, the one where you change numbers to text.
Took me some four days to do it. I spent more than a day figuring out how to add the appropriate number of spaces.

>>57299125
Ooh, what language and how are you going about this?
I've never tried making one of those.
The way I'd do the parentheses is look, from left to right, for a closing parenthesis and then do the arithmetic between that closing parenthesis and the opening parenthesis before before plugging it back in and going to step one... which it looks like you did.
Also, with Java at the very least, because String is immutable, you can use StringBuffer or StringBuilder as mutable versions of String (which cuts down on runtime).
Or something. I helped my sister with her Java homework. That's the only reason I'm aware of that.

>>57299399
Yep that logic is exactly how I did it.
I figure I should be able to apply all of the innermost scoped parenthesis at the same time.

I'm actually using java, and should really get in the habbit of stringbuilder.

>>57299399
Next time use arrays of strings instead of horrible switch cases. Didn't bother to read further, wouldn't hire.

>>57299291
https://en.wikipedia.org/wiki/Shunting-yard_algorithm

>>57299467
If you care for efficiency and getting better, you should look a bit into theory.

In this case into grammars. The whole Term is representable as a tree, with _Term operator Term_ as nodes, where a Term can be either _Term operator Term_ again or just a value, with brackets here and there. A program that transfers the string into such a tree via a grammar is called a parser.
From there you have several options, inline transformation, where you delete a value operator value substring and replace it by its result, or some others, like making a real tree in memory and reduce value operator value pairs to values in a depth first search. Inline transformation is a bit faster.

Also it's normal that you don't really like your first programs, you're not alone there.

Huh? Differential Equations is calculus. It's literally described in calculus. What country are you in?

They are also very applicable in machine learning. My DFQ course also had eigenvalues, PDEs. I thought that was pretty standard. All useful in machine learning, it's a field wide in scope.

Statistics are important for ANYTHING computers, and yeah of course linear algebra too.
I could see your arguments but I still think differential equations is essential to do anything significant.

I'm writing a textboard in Python, and for the last day I've been replacing all manual SQL queries with SQLAlchemy (ORM library). It's condensed the code a bit, but other than that it's looking a lot more "wordier" and generally more difficult to understand (in my opinion) than plain SQL queries. When should I use one over the other?

Okay let me back up and explain the situation.
The app is a UWP mobile app that relies on data from a cloud-hosted database.

In WPF, you could always just write code using SqlDataConnection to connect to a server and query its database. UWP doesnt let you do that, it makes you connect to an external service.

Tried to figure out how to do that, failed.

My workaround was: I can write a python script in like a minute that will just query the Azure and insert into a local sqlite that I DO know how to interface with in UWP.

What I want to know is, what sort of unforeseen bullshit will this workaround land me in? In a sense I like the idea of the local DB because it's not crucial for the data to be 100% up to date to the second, and the app could still function if the internet connection goes out (which I predict it will).

I'm from nz, but I think our uni courses are structures pretty similar to US colleges?

DEs are *described* with calculus but don't seem to be used much in machine learning themselves..

The main parts of calculus I think are relevant to ML are partial derivatives/gradient operator and the multivariate chain rule, (since you have to apply those for backpropagation), which are typically taught in Calc 2/3 not DE.

I mean, eigenvalues are used for PCA, but that's linear algebra, not DEs. When do you have to solve a PDE to implement/understand a ML algorithm?

The main way I think my PDE course helped me in ML was giving me decent intuition about dynamical systems like RNNs. I'm sure it pops up sometimes, but calling it essential seems like a stretch. Is there something I'm missing?

I currently have a little thinking problem in C++:

I have a datatype that consists of several values and a pointer to a field of doubles, that I have to allocate on the heap for certain functionalities.

This datatype itself is held in a std::vector. Assuming I use push_back() on this datatype a lot: Is it enough to overload the assigmnet-operator with one that allocates a new field with a new pointer and copies the values into it, or do I have to do something else? using push_back on the datatype as is would just copy the adress, that would all point to the same field on the heap.

I came from a static field as part of the datastructure to a dynamic field, because the static field was not expandable in runtime.

would you hire someone who's resume includes a research internship with deep learning and developing a couple apps for a junior developer position? i feel like this professor kind of fucked me over. he told me this position would be such a great experience and i'd get so much out of it and i already put it down as my senior honors project and now i'm learning it's zero coding required.

You guys over-think internship pressure so much. I've had four, you can skew anything easily for future jobs. Don't think what you actually do at the internship matters much.

Just learn on your own, don't ever expect people to hold your hand. Go watch some MIT courses for fuck sake. You have all of humanity's knowledge at your fingertips, no excuses.

As a regular linux user I'm trying out windows on my new laptop, and I kind of wish there was a good answer to this question

Most of the time I have like 4 or 5 different terminals open:
* WSL works some of the time, and when I can I just use it + mintty.
* One terminal is dedicated to bash shell that is bundled with git. it works, but _only_ for git.
* One terminal is the visual studio cmd.exe shortcut. Same deal with git, it gets a dedicated terminal.
* and then I have a powershell instance that just does "the tools that don't work in WSL". I haven't bothered learning powershell at all, it just seems like it doesn't give a fuck about anything that isn't written as a C# cmdlet.

Guys, quick I need a RegEx.
What the hell matches any number of repeating lines with any comments?

I need it for a filter.

Say... if there are 1, 2, 3, or even 4 LINES
that all contain similar text repeated several times?
e.g.
>YOU = FAGGOT
>>YOU = FAGGOT
>YOU = FAGGOT
>>YOU = FAGGOT

Basically, how to filter that kind of shitposting?
I was trying this:
/(^.*^>.*$){4,}/i
because my thought was
Any line that begins with some characters, has at least 1 greater than sign, and then has some more characters before the line ends, repeated at least 4 times.
basically, the condition should be

globally match:
any LINE BEGINNING with ">" OR ">>"
repeated multiple times, say at least 4?

physical intuition would suggest just reversing the ray and clamping to each surfaces normal
so for example say your ray is (-1, -2), then the two candidates would be (0, 1) and (1, 0), which would round closest to (0, 1)

>>57305745
I'm not the person who said they were doing the project, those are conclusions I've come to by myself by doing similar stuff myself.

>>57306013

Baby programmer here.
I've gotten too and past (?) pointers in the book I'm following, and it's obvious that they're the whole point of C, along with mixing them with arrays and functions and indirectly fucking with variables and stuff.

But can you explain or can someone direct me to an explanation of ... why? Why are they important, what do they allow you to actually accomplish problem solving wise that you can't do without them? I've heard the quote about being able to solve things with another layer of indirection but...?

I'm just having trouble grasping what its used for? The most I can come up with is that it allows you to change which variable is called in a function, but that does little more for my brain than describe what indirection is in the first place.

>>57306227
As far as I know It's useful for working with raw hardware memory. Which is handy in the context of firmware.

For example, let's say you want to find out how much RAM is unused on your computer. Not by calling some library, of course, but counting each byte yourself.

>logic gates abstract physical wires and electricty
it started off good


>binary abstracts logic gates
>machine code abstracts binary
>C abstracts machine code
but neither of these are true

>>57306292
There are way, way too many reasons, but I'll give you a couple of basic ones. Abstraction is a broad term btw, by writing in C you are using it, by writing in any programming language you are using it.

I'll give an example to references and pointers. Say we wanted to change the first 4 characters of a string to "x". We write a function that takes a character array, iterate over the 4 characters and then pass that array as an argument and done. Well, we then have to return that string to the caller, and then the programmer has to set the string to the return value, because the function copies it.

s = fourx(s);

This is inefficient, in some use cases completely stupid, like in OO languages where objects that aren't strings could be absolutely massive and you don't want to copy them. Better idea.

Take a memory address of the object or variable instead. Then simply deference the pointer (memory address) and modify it directly. In this case

fourx(s);

Simple. OO languages like Java generally don't have pointers as that is all done implicitly and behind the scenes.

>>57306335

I want to point out that while everyone else here is bitching about C versus Java, which is what all these threads break down to, you are doing well with your project and I want to see more out of this.

Don't take the fact that your post isn't asking open ended questions and thus attracting controversy as you being ignored. Good on you for accomplishing things.

>>57306335
I didn't read everything, but the four variable declarations at the top are not unique to each instance of the class.

What you have there are four "class variables", and are shared among all instances of the class. You want "instance variables" which are unique to each instance of the `Sphere` class.

When you declare the variables in `__init__()`, you are making instance variables there. So you actually have two `ID` variables, two `center_point` variables, etc.

Get ride of the class variables up top.

>>57306367

So, it's useful because C doesn't know how to change thing byte by byte in any simpler manner (not literally byte by byte, but 4 bytes by 4 bytes for integers etc.) without giving up the ability for it to be changed in the original program as opposed to a function?

Word barg I know, but I'm still trying to wrap my head around this. Now I understand why people suggest having an irl sempai for C/C++.

>>57306307
Neat bro. It might be a little forward thinking at this point but you probably won't be able to render terribly interesting scenes with just colored spheres. If you are working on a parser you should keep in mind you will probably want to extend it for material properties depending on your illumination model.

>>57306401
What? I think you totally misunderstood, or I did. It's useful because when you pass arguments to a function without using a reference, a pointer/the concept of indirection at all, you COPY the object. Even Java does it, you just don't need to use a pointer on objects because it knows you don't want to copy it.

When you say, in Java
String s = new String("Hello world!");
s points at a string object instance. That is, it basically is a pointer. You just don't have to use the pointer type because it's an OO language and it wraps around these things itself.

The attributes you declare in the Sphere class are "static" so there's no need for that, only initialize the members in the __init__ function.

>>57306401
Hmm, okay I'm going to give this another go, simpler this time.

Let's say you wanted a function that checked if a given integer contained some mathematical property. So the programmer could say if (containsMagic(num));

Now, our function needs to subtract, divide, add, and do all sorts of shit to this number to get a result and find its property. But in doing this, we don't want to fuck up the integer itself. So we'd make a COPY of that integer and do our stuff.

int containsMagic(int thisisacopy) {
  //do math and return true or false
}

int main(void) {

  int i = 2;
  if (containsMagic(i))
    return 1; 
}

That function makes a COPY. This is a reason NOT to use pointers. However, should we have a function that directly that needs to directly modify a variable, we can just make a function that accepts a pointer to it, deference, modify it, and exit without ever needing to copy the whole object like we did above.

Then you start to make a general class and a specific class because you might want to reuse the code some day and suddenly you have twice as many classes as you need, some classes only function is to wrap code together and one class is just a weird way to write a function.
Every class needs operator overloads so you can easily print them in the log, they all need error handling and they all need adapters for the communication as you use different methods for internal and external communication.
Then you get to the point where you spend more time fixing the cmake than you spend on the actual code because all of these problems you are having can be solved by adding this shiny new library.

Is it considered bad practice to use exit in C?

Let's say I have a function that parses command line arguments, if there's anything wrong (e.g. argument that should've been number isn't a number or is missing) the function prints an error message and exits the program. Would I be better off getting the state back to main in form of a flag or something and having main end the program instead?

It feels way cleaner and easier to just use exit for situations like this since I don't have to pass extra shit around, but is it correct?

>>57307567
Who's going to pay the postage for your bandwidth?

>>57307598
I would personally use asserts.

Otherwise it sounds fine to use either, although I'm a C++ user.

Why calling c++ from C is so fucking annoying?

>>57307612
Donations, basically including unused coins in the letters when you feel like it.

>>57307639
because backward compatibility is not forward compatibility.

>>57307598
In the example you gave I would use exit, but most functions shouldn't kill the program if they fail. Errors should propagate back through the call stack until they come to main or another early function.

>>57307615

Isn't that less efficient than a heap? https://en.wikipedia.org/wiki/Search_data_structure

I have some tasks and need to complete them lowest processing time to highest processing time. More tasks will be added to the data structure while tasks are being processed. I don't think I need to have a fully sorted list at all times, and I think insertion/findmin in a heap is more efficient than in a linked list? But I'm not super clear on heapify maintenance costs

Doesn't a heap suit this best? I'm a little shaky on this but I think it has the best runtime for insertion and findmin which is most important to me but I'm a little iffy on the heapfiy maintenance stuff
