I'm learning Ruby and really enjoying the language, but I see some hate for it here..why is that ?

I understand if you prefer compiled languages or as pure preference for another scripting language such as python, but why do you think Ruby sucks ?

so far to me, it seems like a great language and I do not use it for web stuff at all.

If a language doesn't attract new users and it's popularity doesn't grow in years, if it has no established niche and it isn't being actively used for new projects, it's dead. COBOL is dead, Pascal is dead, Lisp is dead and D was a stillborn.

binary search tree in C. I'm trying to stdin string data (call it key here) into a binary search tree. I'm only sharing the part that im trying to figure out. My insert function works fine.

Code#1 ends up changing what root->key is every time. What I'm trying to accomplish simply what code#2 does where root->key never changes but of course with stdin instead of the given strings.

code #1

        line = (char*) malloc (101);                    
    if (inName == NULL) {                            
        printf("\nEnter one line at a time:\n");    
        strcpy(tmp, "");
        fflush(stdout);    
        fgets(tmp, 100, stdin);
        strcpy(line, tmp);
        root = insert(root, line, cflag);
        printf("root: %s", root->key);
        while (strcmp(line, "\n") != 0) {
            strcpy(tmp, "");
            fflush(stdout);    
            fgets(tmp, 100, stdin);
            strcpy(line, tmp);
            if (strcmpCase(line, "\n") != 0) {
                insert(root, line, cflag);
                printf("root: %s", root->key);
            }
        }    
    }

code #2

root = insert(root, "i", cflag);
insert(root, "am", cflag);
insert(root, "gay", cflag);

What's a project I can do in C++ to pretend I know C++? Something that makes use of important/popular C++ concepts and I can mention in an interview as a proof that I am good at C++. I used C and Java during my undergraduate, but I've went into data science / machine learning since then and only been using Python. Never really learned C++

A compiler needs too much domain knowledge, and I never liked compilers in undergrad, an OS is too difficult, a WM would require GUI which I'm not really interested in... a shell? machine learning algorithm implementation? a neural net? I'm not sure if these would use enough core C++ concepts to actually make me pass technical questions about the language. For instance, I have no idea what the guy in pic related is going on about

Are you in a program for the mentally challenged?

>>59248027
Your code is needlessly complicated and is doing a whole bunch of shit it shouldn't need to.
>strcpy(tmp, "");
This is pointless. It is equivalent to tmp[0] = '\0', and the fgets call later already ensures that this is true.
>fflush(stdout);
This is also pointless. Your message should be flushed immediately, because it ended with a newline. If you're concerned about this behaviour not happening, use setvbuf to make sure stdout is line buffered.
>if (strcmpCase(line, "\n") != 0) {
>while (strcmp(line, "\n") != 0) {
>fgets(tmp, 100, stdin);
>insert(root, line, cflag);
Your code has a shitload of duplicated logic. You should be able to write it in such a way that you only need to call these functions once.
>god fuck me, i hope im making sense
No, you're not really.
Are you just trying to get it so you don't have to keep reassigning 'root' like

root = insert(root, line, cflag);

Esoteric programming language interpreters.

Frustrating when the example code knocking about was either
(a) made for an existing interpreter that did not follow spec closely enough and relies on those differences to work
(b) relies on undefined behaviour (in the spec) that has been filled in using god-knows-what behaviour by some unknown existing interpreter
(b) not tested in an interpreter at all therefore buggy (who's gonna look right?)

I don't mind writing my own code in $language but I like to verify my implementation against existed documented examples...and then sometimes those examples fall over and I have to work out which of the above options has happened.

Am I a programming language?

>>59248783
Yes, but even C++ is better than you.

Let me try again

So I'm trying to figure out why my code (#1), which gets an stdin string and puts it into a binary search tree, isn't working like it does when I feed the strings myself.

        // root is a node, cflag is just an option for comparing not relevant to my question
        line = (char*) malloc (101);                
    if (inName == NULL) {
        printf("\nEnter one line at a time:\n");
        fflush(stdout);    
        fgets(line, 100, stdin);
        root = insert(root, line, cflag);
        
        while (strcmp(line, "\n") != 0) {
            fgets(line, 100, stdin);
            insert(root, line, cflag);
        }
    }

        inorder(root);
    postorder(root);

I should be getting a result like I do when I run:

root = insert(root, "i", cflag);
insert(root, "am", cflag);
insert(root,"gay", cflag);

inorder(root);
postorder(root);

But it seems like it forgets what the original root is so when I go to to inorder/postorder I get no result with my first block of code.

>In python I'd have used

That's not the same number though.
A MiB is 1024*1024, while 1e+9 is 1000*1000.
So you can either calculate 1024*1024, or you can do something much less ressource intesive, which is to take the 1 and bitshift it 20 digits to the left. It's a single operation.
Protip: 2^10, 2^20, 2^30, and so on are 1kiB, 1MiB, 1GiB, and so on.

>>59248842

yeah, that's where your kind should fuck off to.

>>59248923
I don't see why not. Programming is programming. Whether it be a native application, a web app, a server-sided application, or what-not, development is the goal, and if you can make it more accessible for your users, why wouldn't you?

I personally use C# for desktop apps, will soon be using Xamarin for android/iOS, use ASP.Net for web servers, and React + Typescript + Less for client-sided web apps.

But if I had my way, I'd be using C/C++ if I could use the React + Typescript + Less setup as the UI, and C/C++ as the under-layer.

    }
    
    // Compares Strings
    int compareResult;
    if (cflag == 1){
        // Case sensitive 
        compareResult = strcmpCase(keyStr, node->key);
    } else {
        // Case insensitive
        compareResult = strcmpNoCase(keyStr, node->key);
    }
    
    // Moves down branches of BST to insert node in correct order
    if (compareResult < 0) {
        node->left = insert(node->left, keyStr, cflag);
    } else if (compareResult > 0) {
        node->right = insert(node->right, keyStr, cflag);
    }
    
    node->count++;
    
    return node;
}

2 string compare functs, a simple inorder and postorder traversal functs, and the following node struct

/* Binary Search Tree Node Struct */
typedef struct Node {
    char *key;
    int count;
    struct Node *left;
    struct Node *right;
} Node;

root is declared as

struct Node *root = NULL;

so my thinknig was i needed to first make the root node if I want to build off it for the tree. And like i said, it works for the simple second block provided in my op with the given strings, but when i try to apply the same logic to stdin something happens that when I try to inorder/postorder traversal output it doesn't start from the original root and therefore i dont get an output.

Curly braces can be omitted for single line statements.
It doesn't make a copy of the array but rather each individual character, you can use int &x to get a reference which will not involve a copy at all.

>>59249350
For debug, keep a linked-list (key, node address) of the nodes themselves so you can dump them to the command line and see if you're really doing what you think you are. But, I am still here, just trying to figure out what could be going wrong.

>>59249253
What language are you writing it in?

Interrupts were a mistake.

>>59249347
That's because there are some unwritten rules (it's more "etiquette") newfags who don't lurk a bit before contributing tend to ignore. Proper formatting is one of them. Another one is /dpt/ not being for web development. Those who break those are usually greeted with ">>>/r/eddit" since that's where most of them come from.

>>59249254
I don't know what the good resources in English are. You'll want to write a (non ambiguous) formal grammar and define semantics for your language. Operational semantics provide the best rigor/sanity ratio in my opinion.
https://en.wikipedia.org/wiki/Operational_semantics
As for the implementation I recommend first focusing on the front-end, since you mentioned you were looking at some high level features such as type inference I figure middle-end and back-end is not what interests you the most. In that regard targetting LLVM might be a good idea.
http://llvm.org/docs/tutorial/

>>59249494
To be fair, /g/ wasn't my first choice. I am just not so sure about posting it to StackOverflow, since it's not directly a programming-related question. But, I'm still sticking around trying to help the guy with the C Binary Tree issue.

I've used a fuck ton of languages for programming, because I strongly believe that a good programmer isn't limited by language. I've used C, C++, C#, Objective-C, LUA, Python, Typescript, Javascript, Java, and PHP.

>>59249491

>>59249549
Whatever guarantees that an interrupt is never missed.
Disabling interrupts is a pretty shitty and hacky method of achieving atomicity in interrupt handlers, but it's literally the only way to achieve it.

>>59249575
Gendo pls

>>59249578
That's why you store them on stack and execute the interrupt when free.
You usually have low and high priority interrupts.

>>59249607
>That's why you store them on stack and execute the interrupt when free.
You mean put them on a workqueue? queues are not stacks. Putting interrupt jobs on a stack makes no sense.
Yeah, the problem with that, is that inserting into the queue kind of needs to be atomic for it to work reliably.
Not only does inserting have to be atomic, but where the hell are you going to get your job struct? you need to dynamically allocate it, which requires going through your allocator.
So using a workqueue involves allocating a struct (potentially long operation) followed by inserting it into the list (very short op) all while interrupts disabled.
You could certainly miss an interrupt while inside the allocator.

>inb4 just copy a static struct into a preallocated contiguous array
Will never work properly.
Not only is that inefficient to maintain, but you have to handle the situation where the array overflows, which pretty much requires a dynamic allocation.


There's no nice way to do things with interrupts, and Linux handles it by simply making "sure" the operations done while interrupts are disabled (including heap allocations) complete fast enough.
Hence they're a mistake.

>>59249727

My only experience is with pic18f452 were it had stack for 31 interrupts?
You are going to have to deal with hard limits. If linux disables them then it probably is the best way to handle them with our limited hardware/software. If you don't like you are free to make your own better kernel.

how does python's "in" work for each different structure: list, set, dict, etc?

>>59249817
No, it's not a problem with the kernel. Linux handles it properly.
The problem is with the interrupt concept. It's fundamentally flawed because it does not guarantee that an interrupt won't be missed when it shouldn't.
At least on the PC platform.

>>59249841
The concept is this:

for every key in collection
key = defined type (string/int/etc)

>>59249869
Doesn't nested interrupts solves this problem?
http://stackoverflow.com/questions/24128926/what-happens-when-an-isr-is-running-and-another-interrupt-happens

>>59249767

Depends on how far you have advanced in C++.

>>59249890

but internally, is it a linear search?

>>59249909
No.
Atomic operations within an interrupt handler requires disabling interrupts while the operation is in progress.
No interrupt can happen while they are disabled, not even nested ones.

>>59246942

Memes apart, where should I start learning to write code?
There are a lot of languages for different purposes and it's difficult to find a way.

>>59249968
Learn Lisp. Then learn whatever else.

from book, from official documentation of the language of your choice.

>>59249968
Figure out what you wanna make first. If you just want to immerse yourself in code, learn Java because it's a real cunt to get going, but forces you to be a nazi with your code.

Once that's done, go to C++

>>59250011
Learn C too. Your education is ultimately up to you, but you shouldn't cherry-pick it.

>>59250032
>this question gets asked so many times...

and anytime gets a different answer. you are suggestin me to start with C (by that K&R suggestion) other user told me about Lisp, others told me just learn python, this guy >>59250033
suggest java.
and so on. that's why this question is made a thousand times. at least with the linux distros you have some advice about beginers vs harder distros. but with coding languages it doesn't seems to happen.

>>59250080
That should be a hint there is no right answer.

>>59250080
I don't know why everyone keeps memeing K&R, it's old af. Still I think C is a good starting language.

>>59250080

you can start anywhere. it just depends on what you're trying to accomplish. k&r's book is very good, if a little outdated, and c is a staple that you'll probably want to learn at some point. that's why i recommended it. lisp isn't a bad recommendation, although if you go that route look into scheme instead. i'd avoid java just so you're not distracted by all the OOP boilerplate code.

Doing more work on my userspace NVMe driver. I'm successfully allocating buffers in userspace and passing them to a skeleton kernel module that simply page locks them and gives back the physical address.

I'm also successful in submitting the initial "Identify Controller" NVM command and getting a result back.

The next step is to add some queue processing logic and make a nice API to submit commands to the disk.

The step after that will be to implement the nvidia_p2p_get_pages() kernel magic so I can begin to host buffers on GPU memory rather than in RAM.

Haskell's goal to be as pure as practically possible is commendable but I found it to be a brake to my productivity on several occasions. In such cases I enjoy the freedom given by OCaml instead. Although I'm quite sure anything that can be done by mixing paradigms can be done purely in Haskell too. That and I find the compiler examples available in OCaml much more understandable. It's basically more about the environment than the language itself.

A language that allows you to prove that should offer semantics for accessing that element directly.

Of course, don't implement Optional<V> just for the sake of it. If you know the element will always exist, then there's no need to.

>>59250786
>How DARE you post name and photo on your github account!!!!

Do you even have a point anymore?

>>59250757
But the language already has null.

If you want to stop a value that might be null in a map then I agree you should use Optional for the value type of the map. But making it so get always returns an Optional regardless of value type? It just gets in the way when you know the key exists, and it adds very little when you don't, because you'll be checking for null at the place you try to get the value out of the map anyway.

How does it add any value at all?

V value = myMap.get(key);
if (value == null) {
    throw new MissingKeyException(key);

If you post your stupid face here don't be surprised when you get called what you are. Now go be retarded somewhere else, like on plebbit.

What language is so "un-deficient" that "patterns" don't eventually emerge and get monikers..? Even FP is full of them (most notably, pattern matching, huar huar)

It's not a pattern, and it's not "avoiding null" or whatever.
The point is, is that it is utterly stupid and retarded to have fake values baked into every type.
That completely defeats the point of custom types.

A bool can be true or false... or null.
An integer can be ... -1, 0, 1, ... or null. Is null 0?
Who knows. Maybe it depends.

Optional<Optional<T>> is not the same as Optional<T>, and that's a good thing.

Optional is isomorphic to Result () / Either (), and to a list that has at most 1 element.


If you think null is a good idea, and optional is a bad idea, then you should go back to using integers and not booleans or enums, arrays of bytes and not structs or unions.

>>59250829
I didn't post it. You looked it up yourself instead of looking at the code.

Are you seriously sperging out because I've somehow "violated" your sacred conception about what 4chan should be? Grow up.

Really now? It's literally on the page you linked to. There is no way someone can ignore it, especially when it's that ugly.
If you actually want any feedback try not posting your work github next time, retard.

Haskell does that too, with ⊥. I guess Haskell is stupid and retarded as well.

Not in Java or C#.

It's my personal github. I only have one account.

It's not.

The default integer type in Java, int, is a primitive. It cannot be null.

Not him, but why are you even on the internet if you get triggered by a profile picture? Do you think 4chan is some secret club or something?

A redditor is someone who posts on reddit.

Spacing quotes has been done on 4chan since the beginning.

Then you should make another one. I highly doubt that I'm the only one who would immediately dismiss even the slightest bit of "value" your "project" might have upon seeing your retarded face.

You're clearly triggered, m8. Take a break from 4chan, do something else, I dunno, go outside, get laid maybe.

>>59251053
We're pretty much all using Github because it's convenient and widespread. So should he make a new account when posting code because some idiot will react to his picture rather than his project? You're an actual moron. No wonder /dpt/ is mostly shit with retards like you.

not the guy you're responding to, but looking up that anon's other repos + name tells me that he is doing some pretty neat stuff, while you're just bitching on 4chan trying to act all "im edgy and anonoomose"

He doesn't have to put his photo on his GitHub profile. He's just vain and narcissistic.

>>59250865
Do you read? Or am I dense.. I was *advocating* the option/maybe/either/etc paradigm, same as you apparently.

Null is a bad idea unless represented/enforced/"problem avoided" by option types, which are a good idea.

Anyway

Correct. Or just remove the image if you can't handle someone calling you a retard.

>>59251155
Are you new to 4chan or something? The name "Anonymous" doesn't mean that there is only one poster. Look at the post timestamps, they are well within the cooldown timer.

People who actually contribute to this thread and want to share more than a fizzbuzz, which you're obviously not part of since you've been shitposting all this time.

Fine if he doesn't like his face. But this thread is about programming, you either post about programming or shut the fuck up. Calling someone names for something irrelevant is GR6 violation.

So your friends from reddit who have names here? How about you and your kind just post there instead? It'll be better for everyone.
Or are you claiming that you can somehow track my posting history?

>>59251234
And thinking that because more than two posts disagree with you they have to be made by the same poster, is something a newfag would believe.

It's not exactly hard to identify individual posters based on their writing style, vocabulary, grammar etc.

Your "le we r anonymous we r leegion" worshipping is misplaced and not welcomed on this board, please take it back to >>>/b/ where it belongs.
