Depth-first traversals of trees come in 3 main varieties: pre, in and post orders.

Depth-first searches of graphs come in 3 main varieties: pre, post, and reverse-post order.

What order does the typical textbook recursive Depth First Graph Search process its nodes in?

  procedure DFS(G,v):
      label v as discovered
      for all edges from v to w in G.adjacentEdges(v) do
          if vertex w is not labeled as discovered then
              recursively call DFS(G,w)

Freshman here, working on a project to zoom in on the mandelbrot set.
It works pretty well until you zoom in to the order of around 2.0E-14 and lower, then pic related happens.

>>60300160
Double epsilon is 1e-16, so 1e-14 is already stretching it.
I don't exactly see the problem. Is it because it's grey? Maybe increase iteration number.

>>60299724
That'll be a lesson for you. You have to divide the responsibilities between each member and have regular (I repeat, regular) meetings om the project. It is important to keep contact with people. Do not micromanage them, but keep an eye on people who you don't exactly trust.

Every class its like "Well I work no matter what when ever you guys meet no matter the time but Ill do some rather insignificant part of the project so i get to put my name on it."

At least in one of my other classes you get to rate your teammates on the effort they put into the project

Is there a non-deepcopy version of strcpy() for C?

>>60301468
Your question makes no sense.

>>60301479
Yeah maybe I'm understanding my problem poorly. I have a string that's apart of a structure that I allocate memory for and when I try to make a copy of that string into another string then free the memory in that copy string the original string gets freed too.

So I'm trying to think if this has a name, or if it's even possible to solve.

I'm trying to model N games of telephone in parallel.

Let's say you have N people in a circle and N starting words. Is there a way pass messages so that everyone will hear each word, and no one will hear from the same person twice? Or is this some group theory provably wrong?

char *new = strdup(orig);

Just copying a char * isn't going to "duplicate" a string.

Gnat is benefiting from the tighter restrictions for identifiers in Ada. For example double underscore is not allowed. C++ doesn't have this luxury.

How do you do text manipulation like this? Either in C or Bash?

Only 36% of software engineers in India can write compilable code based on measurements by an automated tool that is used across the world, the Indian skills assessment company Aspiring Minds says in a report. The report is based on a sample of 36,800 from more than 500 colleges across India. Aspiring Minds said it used the automated tool Automata which is a 60-minute test taken in a compiler integrated environment and rates candidates on programming ability, programming practices, run-time complexity and test case coverage. It uses advanced artificial intelligence technology to automatically grade programming skills. "We find that out of the two problems given per candidate, only 14% engineers are able to write compilable codes for both and only 22% write compilable code for exactly one problem," the study said. It further found that of the test subjects only 14.67% were employable by an IT services company. When it came to writing fully functional code using the best practices for efficiency and writing, only 2.21% of the engineers studied made the grade.

The only remaining question is, why doesn't /dpt/ makes six figures?

I figured it out. I wasn't allocating for the string directly. I was allocating the pointer in the structure for it.

Instead of this:

string = malloc;
structure->str = string;

I was doing:

string = otherstring;
structure->str = malloc;
structure->str = string;

Thanks for trying though guys.

Alright, since I guess this is a better place to ask this than /sqt/, here's a dumbass programming question:

Let's say I have this C code:

#include <stdio.h>

int main(int argc, char * argv[]) {
    while (argc-- > 0) {
        printf("%s == ", *argv);
        char c;
        while (c = *(argv[0]++))
            printf("%c", c);
        printf("\n");
    }
    return 0;
}

And here is the output:

./a.out == ./a.out
-xyz == -xyz
-xvf == -xvf

How is

argv[0]

, and by extension *argv, pointing to the first item in the next array despite the fact that it is not iterated past the terminating

'\0'

?

Make a counter, then clear it when it hits a number like before you add it to the list, ex:

(list here) 
int semicnt = 0;
for (int i = 0; i < ratingsthing.length; i++) {
   if (ratingsthing[i] is a number) {
      if (semicnt > 1) list.add(null);
      list.add(number);
      semicnt = 0;
  }
}

>>60302907
How would you expect to be able to parse the 'null' ratings? How could you parse it when there are extra random semicolons? (The garbage you point to)

Are you sure it isn't just a bunch of ratings delimited by semicolons? (So it might read: 5, 4, null, null, 4...)

>>60302957
Woops also outside the first if statement make an else and do semicnt++

basically, i want it to redo at that point because it eventually fails because of the conclusion reached here, but im not sure how to force prolog to restart that. any ideas?

I think I need to avoid the library after all. On another note, not having lambdas is extremely painful and i want to gouge my eyes out

I'm relatively new to java and to programming and while I think I have a solid grasp on the basics I have a hard time figuring out which is the "correct" way to structure a project.
For example, I'm making a game to practice. It has a main class, which holds an inputlistener instance, a level instance (with tiles instances), and a ui instance. When an input event happens, the inputlistener calls the level, which calls the corresponding tile to handle the event. But the tile should then call the ui to display the correct response, which implies that each tile should hold the instance of the ui (or of the main class), which feels inefficient/wrong to me. Is there a more correct way to do it? It seems like in a sufficiently complex project in which all classes are interdependent, I end up with everything holding instances of everything else. Doesn't that defeat the purpose of OOP?

>>60304717
OOP is impossible to do purely. What I mean by that is that in the real world you get these artificial classes with names that include "manager," "factory," "system," etc. Then you'll get unnatural and weird relations between your classes like you've mentioned. Thus, as you've said, encapsulation of state (The main reason OOP was invented.) gets subverted.

>>60304787
So? The languages that became popular have {{{{{{}}}}}} instead.

Any SQL'ers here? How do I count the results from this query? I can't figure out where to put the COUNT statement.

(SQLite)

SELECT m.*
    FROM TagMap tm, MediaEntries m
        WHERE tm.TagId IN (1, 2, 3)
        AND m.Id = tm.MediaEntryId
    GROUP BY m.Id HAVING COUNT(m.Id) >= ?

I figured just using SELECT COUNT(m.*) ... would work but it doesn't. I do not want to actually return the results and count it in code, because it'll potentially be 1000's of items and I don't want to allocate memory for that.

>>60304779
So the structure as I described it is fine?

>>60304717
>which implies that each tile should hold the instance of the ui (or of the main class)
why would that imply that? just have 1 ui instance

>>60304829
>But the tile should then call the ui to display the correct response, which implies that each tile should hold the instance of the ui (or of the main class)

It has its uses (e.g. GUI programming), but overall I'd avoid it.

>>60304883
Yeah, will probably do that. The problem I see is that handling the input may require interacting with other classes depending on the state of the tile, which would imply passing an instance of each to the method preemptively. Then again, this would also happen if the tiles just hold the instances. Maybe I should pass an instance of the main class through the method and make the instances the main class holds public.

>>60299766
They should. Grades are a joke. Idiotic tests and exams prove absolutely nothing about people's ability to competently perform a task. It's a simple game you play with your professor where you figure out what he wants to hear and write out exactly that, and get a 100% grade for your effort. It's some kind of bulimic learning process where you cram a shit ton of useless factoids into your head before an exam, vomit it all out on the test and then feel good about yourself after you forget everything. Grades aren't really about smarts or competency. They're about effort and time investment. Turns out you can get really good at playing stupid ass games with people if you do it for long enough.

Who cares what actual grades you get? Nobody's ever asked me. Just get your stupid degree so you can put it on your CV and win at yet another stupid game you'll be playing with the recruiters of whatever company you want to work for. These stupid people think degrees are evidence of competence. Give them what they want, get the job and lose exactly zero sleep over that fact.

Are you enthusiastic about programming? You're already above most code monkeys who are in it for the money and don't give a fuck about anything. Don't waste that quality in a soul-sucking classroom playing stupid grade games with some clenched-ass academic who writes absolutely useless papers for tenure. Study by yourself and learn things either because you were curious or actually had to learn them in order to accomplish some actual task. Pick an annoying problem you have, no matter how small, and start a project on GitHub that solves it or automates it away. Fucking finish those projects. Find something to contribute to other people's projects that are useful to you. When people ask for proof of your own competence, show them those projects. Much better than a shitty piece of paper.

Is it trolling?

I need to auth/secure an HTTP request but I'm really shit at it. Asked this in /wdg/ but got no answer. I came up with a 'basic scheme' which works, but I have no idea about how secure it is.
Assuming Alice and Bob share a secret, symmetric key (which Bob can find by Alice's name), my request is:

{
    "origin": "Alice",
    "iv": 123412341234,
    "payload": "AES256(iv, key, payload)"
}

And payload:

{
    "name": "Alice",
    "time": 1494408931,
    "rand": 1963473576417636,
    "data": "Attack at dawn"
}

The server finds the key by the origin name, decrypts the request and checks that
1) origin == name
2) time is at most n seconds ago (against replay attack)

Can I use this to pass around (occasionally sensitive) log data over HTTPS?
The shared AES key does not change. I looked into basic/digest auth/JWT, but the RFC's don't say much about encryption: I don't want my request bodies to end up in plaintext at another server.
I don't really care if the origin names are exposed, they will probably be domain names.
Is there any term for this that I could search for? "HTTP auth" doesn't get me really far.
Any secure, standard method that achieves the same thing?

>>60307347
Because serious people write books or blog posts.

I've got the instances

data Card = Card {
    _suit :: Suit,
    _value :: Value
} deriving Show

data Suit = Heart | Spade | Club | Diamond deriving Show

data Value = Two | Three | Four | Five | Six | Seven | Eight | Nine | Ten |
             Jack | Queen | King | Ace deriving Show

Is there a quick way to make a deck of cards, rather than just manually typing out all 52 cards?

Question: How does Java compare with C# for GUI's nowadays?

>>60307561
> time is at most n seconds ago (against replay attack)
How this prevents replay attack during the time window? Use unique incrementing id for each request instead. Other than that it looks good enough, but I'm not an expert.

>>60307664
Thanks, you're right there should be a request counter

>>60307641
_suit
_card
Absolutely disgusting

>>60307641
Add deriving (Bounded) and use something like

let deck = [ Card { _suit: suit, _value: value} | suit  <- [minBound :: Suit .. maxBound] | value <- [minBound :: Value .. maxBound] ]

>>60303916

fn longest_line(text: &str) -> Option<&str> {
    text.split('\n').max_by_key(|line| line.len())
}

>>60307641
I copypasted this from stack overflow.

import Text.ParserCombinators.Parsec

data Suit = Clubs | Diamonds | Hearts | Spades deriving (Eq,Ord,Enum,Show)

data Rank = Two | Three | Four | Five | Six | Seven | Eight | Nine | Ten
          | Jack | Queen | King | Ace deriving (Eq,Ord,Enum,Show)  

data Card = Card { rank :: Rank
                 , suit :: Suit } deriving (Eq,Ord,Bounded)

instance Show Card where
    show (Card rank suit) = show rank ++ " of " ++ show suit

>>60307745
Then just use [Two..] for a list of ranks, and [Clubs..] for a list of Suits.

>>60307745
What the fuck is this? Is this what programmers do nowadays? Play with toy languages and figure out how to express simple concepts in the most convoluted manner possible?

>>60307726
Oh wait, no need for an Option:

fn longest_line(text: &str) -> &str {
    text.split('\n').max_by_key(|line| line.len()).unwrap_or(text)
}

So what's up with the Go workspace?
Do I just create a folder, and pkg/src/bin folders there, set GOPATH to that folder and create my project folder in src?

>>60307762
I'm pretty sure you can generate instances of Card directly since it derives Bounded, so [Card minBound minBound ..] should give you the list of all cards.

Just make a goddamn interface containing the absolute minimum amount of functionality you need to make something work and use that as a type instead of actual concrete classes. It will let you and other people make your own classes and will make your code easy to test.

What you're describing is a break in operator precedence. I imagine that's actually happening is that you're getting "53" - 3 -> 50.

It does work with VLAs, though. If you're talking about something used with malloc, what you have is a pointer, not an array. Don't confuse the two.

There is no such thing. Again, what you have is a pointer.

Call me when exams successfully weed out pajeets and Chinese cheaters who literally memorize everything in the book without any firm grasp on what any of it means and use any cheating method possible to game the system. Last time I checked, they were at the top of my class, despite sucking at software development. They're good at the academic ritual of studying and passing exams. They memorize the general structure of a problem and also the algorithm to solve it.

I used to get 95th percentile grades on written exams but then I realized what an absolutely abysmal use of my time it was. With these exams, 20% of the work get you 80% of the results. Beyond that it's diminishing returns. So I just study a couple hours before major exams for a passing grade and enjoy my new found free time. I still ace all my practical courses and assignments though, because they're actually useful.

Want something better than grades? Get positive evaluations from people you've actually worked with. Mine are excellent.

i noticed that people who complain about javascript often barely know the language

two examples:
- they don't program (much), they see this meme making fun of javascript and start parroting it to fit in and feel superior to those imaginary programmers
- they're used to their favorite language behaving differently so they give up or don't even bother learning javascript because it's not python or c

there was someone on /wdg/ who said php is better than javascript even though they said earlier that they don't know javascript

Because that isn't an issue I or anybody I know ever had to deal with. ever. It's literally a snippet people use to shitpost about languages they don't use.

Try not mixing numbers and strings in the first place. Nobody does that.

I like to have my code neatly aligned.
I always pad "left" with an extra space so it aligns with "right" while cursing the English language for not making all directional words 5 letters.
Above, below, right are all fine 5 letter words why did you fail at left?

>>60309204
You clearly aren't aware of what VLAs are capable of.

int width = 10, height = 30;
int (*ptr)[height] = malloc(sizeof *ptr * width);

This is a true runtime-sized 2D array. There is no thread of stack overflow, because it's not stack allocated. You cannot do this without VLAs.
I can pass it into a function.

void fn(size_t w, size_t h, int array[w][h]);

I can create functions which actually say something useful about their arguments

void fn2(size_t n, int array[static n]); // array MUST point to an array of at least n members

If I can reason about the size of some argument (which one usually can a lot of the time), you can safely use VLAs in the "normal" way.

But keep saying those grapes are sour.

>>60309284
Lmao what's wrong with it

>>60306218
First of all, yes it does. Any language that supports heap allocation but doesn't have a garbage collector has this "problem."

Secondly, it's not even a problem. It's just a different way of programming.

>It teaches you the truth of immutable state and pure functions.
That's not a truth though, it's just one of many paradigms.

If anything, it's a lie. State is rarely immutable at the hardware level, even when the OS decides it's read-only. Same thing with pure functions: all functions have side effects on the execution state.

>>60309446
I need to disambiguate between javafx.event.Event and Event.Event. But intellij doesn't recognize the first Event in Event.Event as a package name but thinks i mean either of the classes, and inserts a new Event. before that, creating Event.Event.Event

but now that first Event is still one of the classes so it inserts a new event so i got Event.Event.Event.Event

If you're concerned about your wife and family, C# has a fuckton of jobs. If anything, it can help your wife and family by virtue of market value and/or employment prospects.

What would you use?
If we are describing one point in relation to another point, the point above or the point to the right makes sense.
If we are talking about moving in a direction, then I guess up/down makes more sense, but there the consistency is even worse.
In that case I use north, south, east and west and pad the 4 letter words.

You can report it. It's most likely a bot. There are ones that will just fork random large and small repositories, too. I guess mass starring repos is a little less worrisome than mass forking.

any simple way to get the timezone for a country/city/state etc from CLI? like

they probably need me to use browser headers. but then i'd have to parse it anyway

Is it possible to ship a program that doesn't require the end user to install a bunch of shit?

I'd preferably like to reference a some libraries that are just in the root directory and bundle that all up. Every language I look at seems to need dependencies installed like Python or Java.

Assuming the users have Windows 7+ installed, what are my options?

>>60309895

>>60309733
I programmed a clock once and used a timestamp feature, it's a very precise timecode for a specific region. Do you access to anything like that?

>>60309908
i guess maybe not arch and gentoo but the user installs them while setting up the os anyway ??

>>60309895
Well, if you really want to not have any dependencies at all, you could make it a bootable program

Probably more hassle than it's worth

Soliciting opinions: are '10x developers' a thing? What qualities make a programmer more productive?

>>60309908
I'm on Windows 7. No Python.

>>60309895
>Assuming the users have Windows 7+ installed, what are my options?

Windows 7 comes with at least .NET 3.5. Most Windows 7 machines have .NET 4.0 or greater by this point.

You can create a .NET application, and bundle any additional libraries you use with something like Costura.Fody.

At this point, you have a single file to distribute, with no installation: an .EXE that Just Werkz™.

Of course, this assumes you don't want log/config files laying around somewhere. Many simple installers just create a few folders and ensure there's no previous version of the application or file/folder conflicts.

why can i just add

#include <curl/curl.h>

and compile with

$ g++ name.cpp

without having to pass any flags to link the header??

>>60309895
Assuming this is all in the realm of windows based on "Assuming the users have Windows 7+ installed, what are my options?":

You can use something like Pyinstaller or cx_freeze with Python to make standalone Python "programs" I believe. What happens is that these systems bundle an entire Python install and whatever extra libraries you used in the Python script into an .exe file if you're targeting Windows.

This >>60309970 too. If you make something in C# and target .NET 3.5, there won't be a whole dog-and-pony show of installing dependencies. Honestly you might want to look at how Webm for Retards and ShareX do it if you want to go down the C# path. Former uses inno setup, latter simply distributes a .zip file.

Wangdows doesn't come with Python installed. I wish it did.

>>60310016
>not even freely available online

>>60309990
You don't link a header; you link a library. The actual executable code of the library has to live somewhere, and your program needs to know where that is.
Also, if you bother to set up a proper build system (even as simple as a plain makefile), it makes it much less annoying to do.
